The audio sucks, I know! I’m very sorry about this. As a one man show I always do my best to check focus, lighting, white balance, audio, etc, but sometimes things slip through. In this case my lapel microphone failed to record audio, and I did not find out until editing the footage weeks later. From a time perspective, reshooting really wasn’t an option to maintain my schedule. It’s quite reasonable for audiences to expect a certain level of quality from established channels, and for that I do apologize as this was never my intention. I will do my best to ensure this doesn’t happen again in the future, but I’m sure I’m far from being done with making mistakes. I hope you all can enjoy the cool technology that Volvo packs into this engine, and thank you all so much for your continual support of this channel! I hope you’re having a wonderful day!
Engineering Explained after a long time jason explains about his life problems but not giving supplementary content about engineering in the comments😂😂
My family just bought a Volvo XC60 T8 and the only thing that made us hesitant about buying it was the complexity of the drivetrain, but so far it really is an amazing car to drive.
@@AJNpa80 we just sold it last month for the long range polestar xc60t8 they gave me $52k for my trade and I paid msrp for the new one. I literally felt like they were giving me a gift plus I get a state and and federal tax credit = $10k bringing it up so I only really payed $12k to trade in my old xc60t8 it did only have 18k miles on it
Wow, can't beat that with a stick. Know a dude that just sold his GTI for more than he paid for it 2 years ago, guess there are silver linings. My work van went up this year and I could not wait, as long as I tried, got raked, wait lists were unknown, hoping there will be a glut after the correction.
@@AJNpa80 With the federal reserve raising interest rates we will have a surplus of cars in another 3 to 6 months because people won't be able to finance them cheaply. Silver lining of of higher interest rates 😂 hopefully you can snag a deal out of it
Insane how much Volvo has changed their "brand" over the years. Coming from the owner of a 72 144s with a 2 litre OHV engine (and a prior owner of a 89 244), Volvo used to make some of the simplest and most durable cars you could buy. Awesome to see the technology at play here from an engineering perspective, but I could never imagine working on a system like this in my backyard in ten years when it breaks.
Ryan Tyniec Had a nice Volvo SUV in the family for years (Aunt wanted a very safe vehicle for her 3 children) and it's been amazing. Very reliable and good power (Think it's a turbo charged I5)
In Sweden Denmark Poland an other European countries the old Volvos are there mk2s / Ae86s chosen by lads for for tuning, drifts,and track cars ,bullet proof and can be boosted without havin to change internals ,most standard volvo engines can handle double digit Psi from turbo and and be virtually Un kill able out racing ,👍,tip buy any old volve rwd box type the oversize bumper model 80/ 90s, there becoming collectable and pricey ,u can thank me in 2-4 years ,
especially with volvos powerpulse. a diy mechanic pulling a pipe with 12bar of pressure off without the special tool to release the air first will lose their hand
Hi Jason.👋 Amazing Volvo engine technology, awesome whiteboard illustrations, and overall great video. With all that said, the part I found the coolest (for some odd reason😕) was your two frame visual of what just under .08 seconds looks like. Haha. Well done. I love your style of teaching... keep up the great work.👏
People are saying that this engines to complicated, to much to go wrong, service costs etc, tell me what in that engine is so complicated and high service costs? There’s allot of tech in there but it’s all actually pretty simple. There’s virtually no service for the SC and turbo side. The engines not running high boost as the CR ratio is fairly high so the engine should be solid . The amount of sensors etc are almost identical to most conventional turbo cars. The only thing would be the integration of the electric power, however this tech has been out for a decade now and it’s super reliable. I don’t get the issue? have they proven to be unreliable since they launched that engine?
Agreed. Yeah, I’m not here to say it’s reliable or not, I don’t have the data, but so many folks making a conclusion after 5 minutes about an engine that a team of engineers developed for years. If you don’t have data to the contrary, no point in making wild claims about it.
the point is, not engine itself, as the engine can be bulletproof, but in the case it is engineered tolerance of 0.5 on calculations and 1 of things fail can be catastrophic for the engine (obviously they won't explode as in Hollywood films), or if in future will be mounted in mote family or sporty cars (like let say s40 or c30) and you will be like, I want 100hp more so I will slam bigger turbo, and the engine will be like: STOP, or I will fly like a rainbow so high. Sadly they don't over-engineering them anymore.
The issue as I see it is the sheer number of interdependent systems working together. The more systems you have, the greater the chance that one of them will fail within a given period of operation. While the odds of having a large repair bill earlier on in the use of this vehicle are probably not very much higher than for a less complicated model, the difference is likely still significant. The other side of the coin is that this entire design focuses strongly on overcoming turbo-lag while maintaining very high fuel efficiency. It's elegant, but in the end I have to question how much of an advantage that's going to be. Would it perhaps be more worthwhile to drop the supercharger, fit the vehicle with an ultracapacitor, and beef-up the capability of the electric power components? Electric engines give much better torque at low rpm to begin with, and enhancing the hybrid character of this model could well provide equal performance gains.
Volvo continues to amaze me with their powertrain development since the Geely era began. It is great to know that despite the Chinese ownership which many cried would be the end of Volvo, actually allowed the Swedes to remain independent on R&D as well as pump out high quality products that does not feel cheap or low-grade at all.
I've always found this setup interesting, but I've always wanted to hear a mechanics perspective on it since they'll be the ones that fix it when it goes wrong and costing me money.
- emissions control - consumes oil like heck - all that pressure... we'll see with some more time all that I really know of it, well see if with time but seems like the introduction of electric vehicles will soon phase all this out.
Emissions stuff will be an issue, but the turbo and supercharger are both in fairly easy to replace areas. Some of the T5’s before 2019 consumed oil, but all the T6’s and new T5’s have no known issues
It's 2 years later im watching this and wow was that so perfectly informative thank you so much! Any thoughts on how these twin charged engines hold up over time? Still as reliable as we've come to see from volvo?
You would think so, but not really. The only thing in the system that would fail within the 200,000mile range would be the bypass valve - the symptom being a loss of power either down low or up high... or possibly dual torque peaks because it's partially stuck open. The supercharger clutch could prove an issue as well, but it may very not. So long as oil changes are kept up, I see no problems with these new Volvo engines lasting as well as the ones they replaced... but costing less to own. Spark plugs will probably need a faster replacement, but that's about it. Eaton oiled superchargers are very reliable - and this one only operates under acceleration from about 1800RPM to 3500RPM, sitting idle the rest of the time. The turbo is designed to only spool up high, so the wastegate is decently far open, so it isn't seeing much of any action, either. This is how the fuel economy on these things is so good - it's just a simple, high quality, 2.0L naturally aspirated four banger until you hit the gas. The T8 model, with all of its electrics, doesn't add anything complex - every part in that system should last 500,000 miles easily (battery notwithstanding).
We'll have to see how they're looking in 3-5 years before we can decide whether this is a genuinely good engine or not (Good engines don't cost a fortune to keep outside their warranty). The supercharger clutch would be the part I'd worry about - if it's going from stopped to 20,000+ rpm in 0.8 seconds as implied by the video, I can see this part shitting it's guts right out in no time. I have heard that Volvo are doing very well on consumer reliability surveys though, but the D2 and D3 engines are almost all people buy here, and I suspect in a lot of Europe, so the good reliability reports are probably not based on the T6 and T8 level engines.
I agree that we really need a few more years to know how the reliability will truly be for the T6 drive-e engines. So far, they are looking to be as reliable as the engines they have replaced (I6 twin-turbo engines). These engines have been around for a little more than four years, though, so we are not without data. The T6 engines had some initial issues with detonation due to oil getting by the low friction piston rings or some such, but that was quickly resolved. As with any boosted engine - anything that causes detonation or uncontrolled knock can potentially destroy it beyond the point of repair. The clutch itself is going from idle to crank speed from as low as zero to 1,500 RPM~3,500 RPM, the supercharger is geared and will spin from either zero or some idle speed to 20,000 RPM - just like any turbo, but with a bit more force. I suspect the clutch mechanism is basically a torque converter with a lock-up and bypass for higher engine RPMs - very similar to how Volvo does their VVT. That would allow the supercharger to be brought up to speed more gently and would be very reliable, requiring only one solenoid, oil pressure, and a belt drive... but would also mean the supercharger input shaft is likely always moving when the engine is running.
More than a valve, the problem of heat is baked into this kind of solution when you try to do more with less. I just don't see how it could wear less severely than a more standard solution.
The wear is reduced by careful design. Floating bearings for the camshafts, direct injection, wideband sensors, inter-cooler, careful packaging, cold spark plugs, dynamic VVT tuning, tuned exhaust flow, layers of heat shields, aggressive fan response with PWM control... all stuff Volvo, Mercedes, and a few others have been doing for over a decade to great effect. An engine that can handle putting out 450HP+ with just a tune but is only putting out 316HP from the factory is an engine with healthy safety margins.
Leased an XC60 T8 in 2017: got the first one delivered in Texas. Only problem so far is that the engine/drive train is so quiet & powerful (400HP; 0-60 in 4.9s) & the ride so smooth, that it's very easy to exceed the speed limit significantly, if you're not paying attention. With work-at-home & everything else within electric range, the car has complained twice that the gas was getting old: 2 fill-ups in c. 11 months. Lease ended September, 2020. Residual owed: c. $32k; Blue-Book value: $45k. Yes, I bought it.
Great video, very informative. I own a V90 with a T6 engine. It’s very powerful, reliable, and fun to drive. Drives great on the German Autobahn doing 200 kph. I’m very happy with it.
@@frok7744 No issues. I've owned it for 3 years and have 31K miles. The Start/Stop battery went dead a couple of months ago but no big deal (don't use that feature anyway).
I appreciated this video. I am about to purchase a Volvo XC60 T8 which will bring a new way of driving for me. This video helped me understand how the power train works. Thanks.
@@Frejborg About six months ago. I'm using it basically in the city and the the car has only 3.500 km. I live in Brazil and there's only a package which is almost complete. Engine is T8 and S90 has amazing well made interior (B&W with 19 speakers, high quality leather etc) and all the security stuff. It doesn't have temperature control to the back seats (nonsense). And the worse thing is the country where I live wich takes about 40% in taxes. Insane...
It's not reliable. If it's a volvo petrol engine it's just as reliable as any other european car, which means not very reliable. They used to make pretty good diesel engines but they discontinued them.
Corey The FAM I'll disagree, Corey. Every big rig out there is turbocharged, and they last hundreds of thousands of miles, abeit they are built for a different application.
They are a quarter dime here comparison with USA in the mid east arabia. $500- 750 cleaned & maintained out of the donated vehicle. Volvo is too pricey like avocados for maintenance costs here. Lol !
Corey The FAM Idk, they're good engines, but imo, the most impressive ice powertrains put right now are ecoboost engines. They're powerful, reliable, and relatively fuel efficient if you stay out of boost. Plus they're very tuner friendly.
When it comes to Volvo's, you never buy new. You get a slightly used one for half price and trade it in as soon as something goes wrong. Thats how you get the value out of a volvo
BlindAF verɪfɪed exaclty why I love my 2.4 sonata. Naturally aspirated engine will last a while and I get 39 on the highway. No sense in getting a hybrid or smaller car since maintenance and repairs in those turbo 1.5s and electric motors will surpass that of the sonatas 2.4
Lancia delta s4 too supercharged and turbo charged ,,, that set up is actually called twin charging . Supercharger helps to reduce the lag during initial range
Excellent video, Jason! Being somewhat old school, I can’t imagine owning something this complicated, at least not until they had been on the roads for 100,000 miles. Of course, the target market here doesn’t give a rat’s ass about durability, as you pointed out in a previous video. Oh, the audio? I didn’t notice it until I read another’s comment. Maybe he doesn’t understand that not everybody who does TH-cam can afford a small fortune in audio/video equipment, much less studios!🙄
It's cool to see Volvo thinking forward with this system, still I'm wondering if an electric supercharger would have made more sense, but this is definitely a system I'd like to drive... combines a lot of good ideas...
Happy owner of T8 S60, amazing straight line performance, leaves everything in its wake, heavy car so one needs to be careful on twisty roads, but still fun to drive through the bends. Great informative video Jason
I've been dreaming/ trying to imagine a rotating cylinder engine for a long time. The piston is magnetically fixed and gates closing inside the donut shaped cylinder providing back force to combustion. I did a mockup of it in Onshape. I know it's not close to workable, but I wonder if you would be willing to look at it and tell me if you think it's worth perusing?
Well to be perfectly honest, in my humble opinion, of course without offending anyone who thinks differently from my point of view, but also by looking into this matter in a different perspective and without being condemning of one's view's and by trying to make it objectified, and by considering each and every one's valid opinion, I honestly believe that I completely forgot what I was going to say.
Instead of adding all this complexity why not add a variable geometry turbo on a I4? Honda currently makes the K20C1 that produces similar HP and torque figures and it's VERY reliable. It's not even a variable geometry turbo, so that engine has a lot much potential. Furthermore, with the K20C1, it can be tuned to produce numbers that decimate Volvo's twin charged engine. I'm not understanding why add all this complexity that give mediocre metrics (horsepower and torque) when it comes to performance. I'm in no way saying this engine is rubbish or that Volvo is rubbish. However, to a novice, a lot of red flags would be raised.
Well, long term update. I got a 2017 xc90 with this engine, I did get the polestar tune from volvo which added another 25hp? Can't remember. But 87k miles and the supercharger failed, not happy. No lights, warning or errors. Just a dead pedal below 3k rpms. Not acceptable.
Ty, I was currently looking at v60 t8. All this technology seems amazing and I'm not ready to go full EV yet. But asking for all this power from a 2 l engine most certainly has to come with some downfalls. I don't lease I buy and keep for a long time so I will keep away thank you again
@@ryukiddin I also had fuel injector issues, and it killed 2 catalytic converters. No clue why. I run 91 octane and followed all recommended service. The cats were covered under warranty and they cut me a great deal on the labor for the fuel injectors, but these issues are piling up and it makes me nervous since this is my wife's daily driver. I want to dump it, but after just dropping 4k on it, feel I need to keep it at least another year.
I work on vehicles with engine covers as depicted. MFGs need to immediately remove all engine covers from vehicles (and if you own a vehicle with one, take it off and put it in the attic or basement). Engine covers allow the wiring that's under them to get heat soaked beyond tolerances, especially the the wire loom material. EVERY vehicle I've encountered that's 7 yrs old or older with engine covers sees the wire loom and other protective covers and wraps on wiring assemblies being destroyed. You should look into this and post a video about it.
Hell no, an engine this compact with this many moving parts that are all timed together using endless sensors and computer data being exposed to the elements, the rugged bumpy roads, unpredictable throttle control, etc, you're just asking for a big repair bill. This is a new engine, anything new that hasn't been tested in the field by thousands of people will show its true colors when it is. Neat idea, but I doubt this is an engine that'll last you 300,000 kilometers without any big issues. But hey if it does, wow great engineering! I'll just stick to the tried and true engines that have been used by thousands of people and shown to be reliable and great.
If an engine has no supper-charger and not turbocharger the engine will last longer. I have non turbo engines to die at 100k miles about 160k kilometres. But have know engines that have no boost that have lasted 350-400k miles around 1.6x that.
While you use engines that have been tested by thousands, I’ll use engines tested by hundreds of millions!!! (Tongue-in-cheek) Next car is going to be a classic Pontiac. I miss having a big, old car. A 7.6L with room to sit in the engine bay and work on it if I chose to. Easily accessible parts for general maintenance. Simplicity and reliability. I’ve had many cars over my life, and engine bays get more crowded, less accessible, and more electronics to go wrong. Current car, I have to pull the front bumper to change low/high beams, blinkers, and fog lights. Remove a tire and wheel well shrouds to change spark plugs, and the coolant reservoir has a special side tube with a float that measures level, that it can get stuck and throw a dash light even when it’s above the full level to name a few complications. It’s just not worth it. It is more than nostalgia, it was just more owner friendly.
The car itself is apparently 5,100 pounds per the video. I'd bet that the 2.0 engine + turbo + supercharger + electric motor + lithium battery outweighs a 3.0 V6.
I would never ever think of Volvo as a luxury brand or as something worth buying. They will always be an old people brand or heavy machinery to me. Plus now they’re owned by China so just like jaguar and Land Rover, their prices and luxury went up but their actual quality and longevity has gone down. You can’t pour gravel into the cylinders and drive with it like that anymore, unlike some historically tough older models. If you want good low end torque, fuel efficiency and reliability, you just need some basic designs. Like small turbos, narrow cylinders and some strong components. You’ll get an engine with plenty of low end torque, a flat power band and if you don’t have a ton of displacement and weight you’ll get good mileage.
And Incase anyone is confused by my comment, Land Rover and Jaguar aren’t owned by China, they’re owned by TATA motors which is Indian. Which isn’t any better
You made a lot of claims without any fact to back it up. This new Volvo's quality is much better than those old ones produced by Ford. I just don't get why anyone is so obsessed with reliability, I bought a 2018 XC90 T6 Inscription, fully loaded at 73K MSRP, and bought an extended warranty that covers 8 years/100K for 2700 bucks. So even the car worth 0 at the end of 8 year, I'm out less than 10K a year for this car. There are many people like me so there is a big market for luxury vehicles. Also those reliable old models are just not as safe as new vehicles, I value safety, handling, quality and power over reliability.
The T8 engine design is really sophisticated. Hopefully. The 4 cylinder motor can handle all these performance enhancements added to it. Would be nice to see the long-term reliability of the T8 engine
Eaton M90 with a 2.8 inch pulley that made 13 lbs on its own in my old 98 Pontiac Grand Prix GTP pace car... Lol was a ton of fun with around 400 HP to the front wheels only haha
Thank you very much for your description. I have a new Volvo XC60 with T8 and find your explanation very helpful and understandable for something I find very complex.
With an partly eletric car, you can eliminate the need for a turbocharer air compressor (that was used to aid the supercharger early on by letting the Turbo swool up early, effectivly using both at the same time). But with a Hybrid car, the throttle respone is instantaeous. This combined with an intant power boost from the supercharger and boom, you've gotten rid of the need for the air compressor. Sure you could keep it in if you wanted, but thats just one more complicated system that will require maintanence down the road.
So?? Where does he say that you cant have turbos and electric motors? He said that you don't need an air compressor.. Which the V60 hybrid doesn't have.
I know this is an old video, but the T6’s have proved to have very few issues since it’s introduction. Some T5’s had oil consumption issues for a few years, but the T6’s are still functioning perfectly well. Proper maintenance is obviously key, but I have yet to hear from any other T6 owner that they’ve had a turbo or supercharger go bad. Even if they do, they’re both in very easy to reach spots. Not nearly as complex as you’d expect. As with any euro car, I’m expecting to do some sort of major maintenance when plastics eventually go bad, but 100k miles and 6 years have gone by and mine is still running like a top
Martin van Weperen Of course a 240 and 740 is reliable, but without knowing for sure i can assume newer volvos wont last long without expensive maintainance, volvo is boring and out of character these days if you ask me...
ErwinSchrodinger64 My 2005 V70 D5 has never let me down, had it 5 years now, the only issue in all that time has been a dodgy abs ecu module, rebuilt for £195 plus £150 fitting, don't be brainwashed by all the fake reliability reports on here !! spread by Audi/BMW fanboys !!!!!!!!!
This is an engine meant for wowing new car buyers. This engine will not last without having copious amounts of money thrown at it, be it from the warranty or from the unlucky SOB that bought it without a warranty.
It's a Volvo engine. It will have no difficulty lasting as it's far more overbuilt than you think... you can probably push the engine to >500HP without changing internals or even reducing service life. It will need quality oil and more frequent spark plug changes, but that's it. Direct injection eliminates most risk of predetonation and knock killing the engine (as you don't have an air-fuel charge, only air, then the fuel injects when it's time to ignite). The supercharger is oiled by the engine (most likely - I haven't checked - but Volvo is pretty aggressive with their lubrication) and will usually be clutched to the off state - only coming on under heavier acceleration. The wastegate is left bleeding exhaust so that the turbo only begins a good spool around 3,200 RPM - very late by Volvo's standards, but very good for fuel economy and reliability - so not even the turbo works hard. Superchargers last according to their lubrication and design. The one here is always getting fresh oil and is usually going to not be doing any work at all. On an engine with 200,000 miles, even with someone with a lead foot, the supercharger will likely only be engaged for 1/10th of that time - likely even less, since it is disengaged for cruise, coasting, light throttle, or high RPM... The clutch and the bypass valve are the only things that might prove to be issues, but these types of parts already exist and have a strong track record of reliability.
People only remember the old box volvos from decades ago which did last a long time, its telling that you don't see many newer gen "old" volvos still on the road.
Based on the way a lot of Model S's seem to be suffering from drivetrain failures even with barely any drivetrain, I'll stay with a proven reliable designs over theoretically reliable designs.
D Jay T I disagree. This isn’t really over engineered in my opinion, as the individual components are still rather simple, their interactions are complex, but not overly so as far as I’m concerned.
*It's supercharged, turbocharged, electric, and will explode in 5 years.* Good luck finding a mechanic that wants to work on this 8 years down the line.
More like the wrecking yard at that point, that's the reality when labor hours total a car. You can line up, but no ones paying, because its a disposable car once off lease and princess returns her car.
When you mentioned that Volvo didn't stop with just super & turbo charging the first thing that came to mind was nitrous. A volvo with a bottle in the trunk. Now that would get them some awards.
very Cool Video! i began Wrenching as a Teenager on 1970s Volvos and have always wondered how they changed over the years not suprisingly they are still Engineered Awesome Mechanically as they were in the Automotive engines and their Marine Division years ago i’m a big fan of Turbocharging and Supercharging and from what you explained and what i’ve read it sounds like the XC 90 is something i may be interested in purchasing i recall that a few years ago they did not meet my Towing Capacity Requirements and i had to Pony Up on buying A American made Adually DeiselTurbo Charged Truck that other than the high price Tag and lower FuelEconomy than Advertised i’ve been quite happy with for many years of good service overall
BrabusBandit Is there proof that its unreliable or are you saying that due to the complexity of the engine. I’m genuinely asking because people in the comments say anything based on any given common, unmediated grounds such as simple = unreliable.
How do you know it isn't reliable? People make claims but never back it up with any sources/data. I like talking about cool technology, and will continue to!
Dolton Collins Been watching Matt Farah's podcast on 'thesmokingtyre', he's a huge car reviewer. And his press car had a tonne of issues including engine related. His friends have had issues with the engine and even his mum who has and XC90 with a super and turbo charged engine. So no guess work here!
Engineering Explained I understand that, and the technologies are cool! But I reckon they're only cool if they work. As described above a number of people have had issues which is a shame. I also understand there is a lot of key-board worriers who'll just say its rubbish because of brand preference without any data, but as mentioned.. People are having reliability issues!
I'm sure if you were to ask Matt Farah he too would agree that three anecdotes do not make a trend. I'm not saying the engine is or is not reliable, but a small pool of anecdotes is not a great thing to base your decision on.
Dear all that is unholy, it must break. It will break. It will drain your wallet. Feel sorry for the suckers who attempt to tune this engine for more horsepower.
Polestar makes one with 415 hp and 500ft-lb of torque.. ..The people that would buy this car are most likely baby boomers and soccer moms. Not exactly tuner types. I'm sure the engine will be just as reliable as its past counterparts, its the transmission I'm worried about.
An engineering marvel, yes it is. But is it necessary or will it be reliable? It's overly complex & I'm surprised you skipped that aspect in your review.
Having sat through the Volvo UK launch of the new engine architecture (they launched the D4 here as the first one), the diesel and petrol engines also share a lot of the basic structural design. Obviously different heads and slightly beefier block for the derv but they were keen to stress this was a ‘single engine architecture’.
tootingbskaevolo those old engines where one of the best especially the v6 and v8. These new ones are too complicated with abysmal real world efficiency.
Great explanation: how does the supercharger switch on or off? What causes the clutch to engage or disengage? Is the supercharger engagement/disengagement point adjustable and how?
Got a T8 and it is quick, but there is alot of power going through the front wheels. I just feel that a more rear wheel drive emphasis would make for a better drive.
i love the way they joined the super charger, turbo charger and the electric motor all in one, It's down right amazing ! volvo, really pulled out all the stops and thought about everything. but the real question that comes to mind is fuel economy? how much fuel will this engine take? fuel prices go up and down like there no tomorrow. So, how would that take roll in all this ?
Thanks Jason for another excellent presentation. This Volvo's engine, however, is ridiculously complicated and I'm not sure why the award... the weight of the car was too much for a 2 litre, 4 cylinder engine so they started adding up all that? Quite silly in my view... there are other options out there to move that huge SUV more efficient than this adding up engine. Definitely not the car of the future and for the common folk. Thanks again for your excellent work and for sharing your hard worked knowledge with us!
BMW has a similar setup in their 225xe except they use a small variable pitch turbo instead of the supercharger, it spools up from 1200 rpm, then a bigger fixed turbo and an 80kw motor on the rear axle. 225hp from a 1.5lt 3 cylinder engine!
Another great video. Thanks again. No worries for the sound, but thanks for being honest. And what have Volvo done is save on money and space, so that they can fit this in more vehicles, like big SUV's and small family cars like the V40 with it's T3 engine, which is the same as the T4, but less software tuning. And the T4 is the same as the T5, without the some more tuning. This saves on engineering, testing and others. And this is for the newest engine codes, as the old ones were different. The T3 was 1,6l, T4 was 1,6l 4 cyl, the T5 was 2l but 5 cyl. the T4 got 2.0l 4 cyl, and the T3 too. So a bit confusing over a 10 year period. Mainly, the difference is in refinement, as a 4cyl engine producing horsepower of a 6 cyl engine. It feels different. The 6cyl 3.0l engines of the germans are more quiet and refined, they feel smoother. But hey, Kudos for Volvo, for applying tech to achieve this.
I will say although the engine is complex and many worry about cost to repair, Volvo has a lifetime warranty on any part the customer pays to replace... So if your super charger goes out and you pay to replace it your covered for life....
Hey, Jason ! So what if the sound wasn't 100% , if there was "too much this" or "too little that" !! I enjoyed it A LOT ! BTW, I always enjoy when you go into your "white board mode",. It's very instructive and you have the gift of making things very simple and interesting. Keep up the good work !! :)
You should do a video comparing running an old V8 car Vs. changing your car every few years for a newer model. Would be good to see (on average mileage) what would be best cost wise, most hassle, most damaging to the environment etc.

It’s quite reasonable for audiences to expect a certain level of quality from established channels, and for that I do apologize as this was never my intention. I will do my best to ensure this doesn’t happen again in the future, but I’m sure I’m far from being done with making mistakes. I hope you all can enjoy the cool technology that Volvo packs into this engine, and thank you all so much for your continual support of this channel! I hope you’re having a wonderful day!
Engineering Explained after a long time jason explains about his life problems but not giving supplementary content about engineering in the comments😂😂

Engineering Explained, can you use Microsoft Paint or something instead of the small whiteboard? Your handwriting is not the best.
Great video brother despite the audio
you are the best man
Now Volvo just needs to make an engine that's Turbocharged, Supercharged, Electric, and Nitrous Injected!
Top 10 Don't go giving them any big ideas . It sounds like they just might do it on a track version.
Then add a rocket engine in the back of the car!
Add a steam engine as well
methanol injected
With port and starboard attachments =)
My family just bought a Volvo XC60 T8 and the only thing that made us hesitant about buying it was the complexity of the drivetrain, but so far it really is an amazing car to drive.
The complexity itself is big no for the long run, rather have a gas guzzling v8 n/a anyday
That's a second owner kind of problem 😉
@@AJNpa80 we just sold it last month for the long range polestar xc60t8 they gave me $52k for my trade and I paid msrp for the new one. I literally felt like they were giving me a gift plus I get a state and and federal tax credit = $10k bringing it up so I only really payed $12k to trade in my old xc60t8 it did only have 18k miles on it
Wow, can't beat that with a stick. Know a dude that just sold his GTI for more than he paid for it 2 years ago, guess there are silver linings. My work van went up this year and I could not wait, as long as I tried, got raked, wait lists were unknown, hoping there will be a glut after the correction.
@@AJNpa80 With the federal reserve raising interest rates we will have a surplus of cars in another 3 to 6 months because people won't be able to finance them cheaply. Silver lining of of higher interest rates 😂 hopefully you can snag a deal out of it
has supercharger, has turbocharger combined with electric motor...
but no vtec
0/10
and no stickers on the car, like psshhh where did that money on R&D go?
At the beggining of the video it showed that the double overhead camshafts can rotate to change their profile?
Isnt that variable valve timing ?
Hartsock Thomson not true vtec!
Why not?It has to kick in so your ass feels it eh?
Go get your mommy buy you skateboard.
Insane how much Volvo has changed their "brand" over the years. Coming from the owner of a 72 144s with a 2 litre OHV engine (and a prior owner of a 89 244), Volvo used to make some of the simplest and most durable cars you could buy.
Awesome to see the technology at play here from an engineering perspective, but I could never imagine working on a system like this in my backyard in ten years when it breaks.
Ryan Tyniec Finally a volvo guy who agrees with me
Ryan Tyniec Had a nice Volvo SUV in the family for years (Aunt wanted a very safe vehicle for her 3 children) and it's been amazing. Very reliable and good power (Think it's a turbo charged I5)
volvo is an amazing brand that gets little if any love and its a damn shame
You could say that most cars on the road today are extremely boring and dry, that doesn't make them bad cars.
In Sweden Denmark Poland an other European countries the old Volvos are there mk2s / Ae86s chosen by lads for for tuning, drifts,and track cars ,bullet proof and can be boosted without havin to change internals ,most standard volvo engines can handle double digit Psi from turbo and and be virtually Un kill able out racing ,👍,tip buy any old volve rwd box type the oversize bumper model 80/ 90s, there becoming collectable and pricey ,u can thank me in 2-4 years ,
RIP DIY mechanics
ForTehNguyen we're a slow dying breed
Well vw made tvinturbo engine 2007 like engine code BMY. Easy to maintane for diy mechanics
especially with volvos powerpulse. a diy mechanic pulling a pipe with 12bar of pressure off without the special tool to release the air first will lose their hand

Hi Jason.👋 Amazing Volvo engine technology, awesome whiteboard illustrations, and overall great video. With all that said, the part I found the coolest (for some odd reason😕) was your two frame visual of what just under .08 seconds looks like. Haha. Well done. I love your style of teaching... keep up the great work.👏
People are saying that this engines to complicated, to much to go wrong, service costs etc, tell me what in that engine is so complicated and high service costs? There’s allot of tech in there but it’s all actually pretty simple. There’s virtually no service for the SC and turbo side. The engines not running high boost as the CR ratio is fairly high so the engine should be solid . The amount of sensors etc are almost identical to most conventional turbo cars. The only thing would be the integration of the electric power, however this tech has been out for a decade now and it’s super reliable. I don’t get the issue? have they proven to be unreliable since they launched that engine?
Agreed. Yeah, I’m not here to say it’s reliable or not, I don’t have the data, but so many folks making a conclusion after 5 minutes about an engine that a team of engineers developed for years. If you don’t have data to the contrary, no point in making wild claims about it.
The Chinese bought a lot of tech for a very cheap price when they picked up Volvo from Ford. Probably one of the best bargains ever.
Engineering Explained totally agree mate
the point is, not engine itself, as the engine can be bulletproof, but in the case it is engineered tolerance of 0.5 on calculations and 1 of things fail can be catastrophic for the engine (obviously they won't explode as in Hollywood films), or if in future will be mounted in mote family or sporty cars (like let say s40 or c30) and you will be like, I want 100hp more so I will slam bigger turbo, and the engine will be like: STOP, or I will fly like a rainbow so high. Sadly they don't over-engineering them anymore.
The issue as I see it is the sheer number of interdependent systems working together. The more systems you have, the greater the chance that one of them will fail within a given period of operation. While the odds of having a large repair bill earlier on in the use of this vehicle are probably not very much higher than for a less complicated model, the difference is likely still significant.
The other side of the coin is that this entire design focuses strongly on overcoming turbo-lag while maintaining very high fuel efficiency. It's elegant, but in the end I have to question how much of an advantage that's going to be.
Would it perhaps be more worthwhile to drop the supercharger, fit the vehicle with an ultracapacitor, and beef-up the capability of the electric power components? Electric engines give much better torque at low rpm to begin with, and enhancing the hybrid character of this model could well provide equal performance gains.
Sounds like a EE video from the early days. good for the nostalgia.
Hahaha, unfortunately yes!
Nope - the drawings are too good :-D...
Volvo continues to amaze me with their powertrain development since the Geely era began. It is great to know that despite the Chinese ownership which many cried would be the end of Volvo, actually allowed the Swedes to remain independent on R&D as well as pump out high quality products that does not feel cheap or low-grade at all.
Its literally an engineering masterpiece 👌
I've always found this setup interesting, but I've always wanted to hear a mechanics perspective on it since they'll be the ones that fix it when it goes wrong and costing me money.
- emissions control
- consumes oil like heck
- all that pressure... we'll see with some more time
all that I really know of it, well see if with time but seems like the introduction of electric vehicles will soon phase all this out.
It's totalled without crashing.
Emissions stuff will be an issue, but the turbo and supercharger are both in fairly easy to replace areas. Some of the T5’s before 2019 consumed oil, but all the T6’s and new T5’s have no known issues
It's 2 years later im watching this and wow was that so perfectly informative thank you so much! Any thoughts on how these twin charged engines hold up over time? Still as reliable as we've come to see from volvo?
Alternative headline: “New Volvo engine has highest cost of lifetime maintenance ever produced.”
You would think so, but not really. The only thing in the system that would fail within the 200,000mile range would be the bypass valve - the symptom being a loss of power either down low or up high... or possibly dual torque peaks because it's partially stuck open. The supercharger clutch could prove an issue as well, but it may very not. So long as oil changes are kept up, I see no problems with these new Volvo engines lasting as well as the ones they replaced... but costing less to own. Spark plugs will probably need a faster replacement, but that's about it.
Eaton oiled superchargers are very reliable - and this one only operates under acceleration from about 1800RPM to 3500RPM, sitting idle the rest of the time. The turbo is designed to only spool up high, so the wastegate is decently far open, so it isn't seeing much of any action, either. This is how the fuel economy on these things is so good - it's just a simple, high quality, 2.0L naturally aspirated four banger until you hit the gas.
The T8 model, with all of its electrics, doesn't add anything complex - every part in that system should last 500,000 miles easily (battery notwithstanding).
We'll have to see how they're looking in 3-5 years before we can decide whether this is a genuinely good engine or not (Good engines don't cost a fortune to keep outside their warranty). The supercharger clutch would be the part I'd worry about - if it's going from stopped to 20,000+ rpm in 0.8 seconds as implied by the video, I can see this part shitting it's guts right out in no time. I have heard that Volvo are doing very well on consumer reliability surveys though, but the D2 and D3 engines are almost all people buy here, and I suspect in a lot of Europe, so the good reliability reports are probably not based on the T6 and T8 level engines.
I agree that we really need a few more years to know how the reliability will truly be for the T6 drive-e engines. So far, they are looking to be as reliable as the engines they have replaced (I6 twin-turbo engines). These engines have been around for a little more than four years, though, so we are not without data. The T6 engines had some initial issues with detonation due to oil getting by the low friction piston rings or some such, but that was quickly resolved. As with any boosted engine - anything that causes detonation or uncontrolled knock can potentially destroy it beyond the point of repair.
The clutch itself is going from idle to crank speed from as low as zero to 1,500 RPM~3,500 RPM, the supercharger is geared and will spin from either zero or some idle speed to 20,000 RPM - just like any turbo, but with a bit more force.
I suspect the clutch mechanism is basically a torque converter with a lock-up and bypass for higher engine RPMs - very similar to how Volvo does their VVT. That would allow the supercharger to be brought up to speed more gently and would be very reliable, requiring only one solenoid, oil pressure, and a belt drive... but would also mean the supercharger input shaft is likely always moving when the engine is running.
More than a valve, the problem of heat is baked into this kind of solution when you try to do more with less. I just don't see how it could wear less severely than a more standard solution.
The wear is reduced by careful design. Floating bearings for the camshafts, direct injection, wideband sensors, inter-cooler, careful packaging, cold spark plugs, dynamic VVT tuning, tuned exhaust flow, layers of heat shields, aggressive fan response with PWM control... all stuff Volvo, Mercedes, and a few others have been doing for over a decade to great effect.
An engine that can handle putting out 450HP+ with just a tune but is only putting out 316HP from the factory is an engine with healthy safety margins.
Leased an XC60 T8 in 2017: got the first one delivered in Texas. Only problem so far is that the engine/drive train is so quiet & powerful (400HP; 0-60 in 4.9s) & the ride so smooth, that it's very easy to exceed the speed limit significantly, if you're not paying attention. With work-at-home & everything else within electric range, the car has complained twice that the gas was getting old: 2 fill-ups in c. 11 months. Lease ended September, 2020. Residual owed: c. $32k; Blue-Book value: $45k. Yes, I bought it.
gonna buy a Xc90 T8. wondering what would happen if gas get old?
Great video, very informative. I own a V90 with a T6 engine. It’s very powerful, reliable, and fun to drive. Drives great on the German Autobahn doing 200 kph. I’m very happy with it.
@@frok7744 No issues. I've owned it for 3 years and have 31K miles. The Start/Stop battery went dead a couple of months ago but no big deal (don't use that feature anyway).
In other words, this is a vehicle you'd want to lease, not buy.
So every year change the displacement of the engine by a 10th of a liter in order to win that award every year
Don't forget to keep the power, that is the tricky part.
Lol
Yup.....lol
I appreciated this video. I am about to purchase a Volvo XC60 T8 which will bring a new way of driving for me. This video helped me understand how the power train works. Thanks.
Did you get that Volvo you mentioned? Tell us about it!
It's...
*HYPERCHARGED!!!*
Now imagine if this was a five cylinder.. I get why they stopped making them but I will forever miss the real T5.. Best engine sound ever!
Agreed, I owned one too.
Perfect. Thanks. I've got a S90 and it's impressive. Hope this high complex engine is reliable. Congratulations for this amazing channel.
How long and how many kms on your s90? Which trim level?
@@Frejborg About six months ago. I'm using it basically in the city and the the car has only 3.500 km. I live in Brazil and there's only a package which is almost complete. Engine is T8 and S90 has amazing well made interior (B&W with 19 speakers, high quality leather etc) and all the security stuff. It doesn't have temperature control to the back seats (nonsense). And the worse thing is the country where I live wich takes about 40% in taxes. Insane...
It's not reliable. If it's a volvo petrol engine it's just as reliable as any other european car, which means not very reliable. They used to make pretty good diesel engines but they discontinued them.
That frame by frame example... man you are a great educator! 👌👌
Thanks!
Old school Vortec 5.7 and the 5.3 should be award winning of their reliability and low maintenance motor 👍
Corey The FAM I'll disagree, Corey. Every big rig out there is turbocharged, and they last hundreds of thousands of miles, abeit they are built for a different application.
They are a quarter dime here comparison with USA in the mid east arabia. $500- 750 cleaned & maintained out of the donated vehicle. Volvo is too pricey like avocados for maintenance costs here. Lol !
Corey The FAM Idk, they're good engines, but imo, the most impressive ice powertrains put right now are ecoboost engines. They're powerful, reliable, and relatively fuel efficient if you stay out of boost. Plus they're very tuner friendly.
Corey The FAM. You obviously don't know what you are talking about, look up the b230....
Corey The FAM btw a AMC/Chrysler 4.2 and 4.0 put your engine to shame in reliability along with the Volvo B platform 😂
Efficiency means nothing if the purchase price, maintenance, and repairs cost you thousands more than something more simple.
BlindAF verɪfɪed exactly, people don't understand the benefits do not outweigh the downsides
When it comes to Volvo's, you never buy new. You get a slightly used one for half price and trade it in as soon as something goes wrong. Thats how you get the value out of a volvo
Which is why the aim of engineering such engines is to have all this functionality without sacrificing on significant maintenance costs...
BlindAF verɪfɪed exaclty why I love my 2.4 sonata. Naturally aspirated engine will last a while and I get 39 on the highway. No sense in getting a hybrid or smaller car since maintenance and repairs in those turbo 1.5s and electric motors will surpass that of the sonatas 2.4
BlindAF verɪfɪed volvo the company that over charges there customers and removes your right to repair.
Volvo is underrated.
They make lovely construction machinery alright :-P...
Yes and make even better cars !!
Gandalf721 someone has to pay for the R&D for the safest vehicles
volvos after 2009 are trash.
Damn right, they are.
Lancia delta s4 too supercharged and turbo charged ,,, that set up is actually called twin charging .
Supercharger helps to reduce the lag during initial range
so is the Lancia 037 and the Nissan Micra Superturbo
037 is only supercharged
keesie75 you are right... messed it up. i thought both the s4 and the 037 were twin charged.... my bad
Mate 2012 and 13 VW Polo is super and turbo charged. Well the repair cost is massive on these engines.
Excellent video, Jason! Being somewhat old school, I can’t imagine owning something this complicated, at least not until they had been on the roads for 100,000 miles. Of course, the target market here doesn’t give a rat’s ass about durability, as you pointed out in a previous video.
Oh, the audio? I didn’t notice it until I read another’s comment. Maybe he doesn’t understand that not everybody who does TH-cam can afford a small fortune in audio/video equipment, much less studios!🙄
It's cool to see Volvo thinking forward with this system, still I'm wondering if an electric supercharger would have made more sense, but this is definitely a system I'd like to drive... combines a lot of good ideas...
Your dream came true I guess, only 3-4 years later 😀
Repair nightmare award 🥇
My last car was a VW SCIROCCO 1.4T DSG with a twincharger engine...turbo + supercharger...90.000km trouble free 👍
I love this idea of throwing every technology available into a car's engine!
Happy owner of T8 S60, amazing straight line performance, leaves everything in its wake, heavy car so one needs to be careful on twisty roads, but still fun to drive through the bends.
Great informative video Jason
I've been dreaming/ trying to imagine a rotating cylinder engine for a long time. The piston is magnetically fixed and gates closing inside the donut shaped cylinder providing back force to combustion. I did a mockup of it in Onshape. I know it's not close to workable, but I wonder if you would be willing to look at it and tell me if you think it's worth perusing?
This was beautifully expained, making the automotive world as we know it even more fabulous
Well to be perfectly honest, in my humble opinion, of course without offending anyone who thinks differently from my point of view, but also by looking into this matter in a different perspective and without being condemning of one's view's and by trying to make it objectified, and by considering each and every one's valid opinion, I honestly believe that I completely forgot what I was going to say.
Eye Dupppz good ☝!
You should be the PC police.
Lol
Pardon me sir, but I think you lost something.
You were going to say... Don't buy any car with this engine that doesn't have a lifetime warranty.
I have a T8. Love it. But man it's a lot to go wrong when it's time to get emissions done.
Instead of adding all this complexity why not add a variable geometry turbo on a I4? Honda currently makes the K20C1 that produces similar HP and torque figures and it's VERY reliable. It's not even a variable geometry turbo, so that engine has a lot much potential. Furthermore, with the K20C1, it can be tuned to produce numbers that decimate Volvo's twin charged engine. I'm not understanding why add all this complexity that give mediocre metrics (horsepower and torque) when it comes to performance. I'm in no way saying this engine is rubbish or that Volvo is rubbish. However, to a novice, a lot of red flags would be raised.
overly complex.
This engine is insane! I have never had as much fun as I did in the XC90...for a SUV. Check out my review of the XC90...I had a blast!
Great video! This engine seems incredible. Keep up the awesome work, Jason!
Well, long term update. I got a 2017 xc90 with this engine, I did get the polestar tune from volvo which added another 25hp? Can't remember. But 87k miles and the supercharger failed, not happy. No lights, warning or errors. Just a dead pedal below 3k rpms. Not acceptable.
Ty, I was currently looking at v60 t8. All this technology seems amazing and I'm not ready to go full EV yet. But asking for all this power from a 2 l engine most certainly has to come with some downfalls. I don't lease I buy and keep for a long time so I will keep away thank you again
@@ryukiddin I also had fuel injector issues, and it killed 2 catalytic converters. No clue why. I run 91 octane and followed all recommended service. The cats were covered under warranty and they cut me a great deal on the labor for the fuel injectors, but these issues are piling up and it makes me nervous since this is my wife's daily driver. I want to dump it, but after just dropping 4k on it, feel I need to keep it at least another year.
Hell, they might as well add warp drive too.
I work on vehicles with engine covers as depicted. MFGs need to immediately remove all engine covers from vehicles (and if you own a vehicle with one, take it off and put it in the attic or basement). Engine covers allow the wiring that's under them to get heat soaked beyond tolerances, especially the the wire loom material. EVERY vehicle I've encountered that's 7 yrs old or older with engine covers sees the wire loom and other protective covers and wraps on wiring assemblies being destroyed. You should look into this and post a video about it.
Hell no, an engine this compact with this many moving parts that are all timed together using endless sensors and computer data being exposed to the elements, the rugged bumpy roads, unpredictable throttle control, etc, you're just asking for a big repair bill.
This is a new engine, anything new that hasn't been tested in the field by thousands of people will show its true colors when it is.
Neat idea, but I doubt this is an engine that'll last you 300,000 kilometers without any big issues. But hey if it does, wow great engineering!
I'll just stick to the tried and true engines that have been used by thousands of people and shown to be reliable and great.
If an engine has no supper-charger and not turbocharger the engine will last longer.
I have non turbo engines to die at 100k miles about 160k kilometres.
But have know engines that have no boost that have lasted 350-400k miles around 1.6x that.
That's exactly what I was thinking sacr3 - so much to go wrong on this thing and I would never want to own one out of warranty.
I would just buy a tesla.
The easiest thing ever to troubleshoot as everything has a sensor probably even your seats to weigh you.
While you use engines that have been tested by thousands, I’ll use engines tested by hundreds of millions!!! (Tongue-in-cheek)
Next car is going to be a classic Pontiac. I miss having a big, old car. A 7.6L with room to sit in the engine bay and work on it if I chose to. Easily accessible parts for general maintenance. Simplicity and reliability.
I’ve had many cars over my life, and engine bays get more crowded, less accessible, and more electronics to go wrong. Current car, I have to pull the front bumper to change low/high beams, blinkers, and fog lights. Remove a tire and wheel well shrouds to change spark plugs, and the coolant reservoir has a special side tube with a float that measures level, that it can get stuck and throw a dash light even when it’s above the full level to name a few complications.
It’s just not worth it. It is more than nostalgia, it was just more owner friendly.
Kuro Murasaki, I heard those old pontiacs had a fold out couch in those engine bays. lol gotta love the classics.
Volvo truly made this s90 as complicated as possible. Maintenance and repair costs will be an absolute nightmare for the average person.
So we are using today 80's group b rally technology, great!
Reinaldo Gonzalez yeah Lancia fan spoted 😍😍
Could also say: So we're using the same four strokes that are well over a hundred years old!? Wonderful!
i'm very glad to see this kind of technology on streets, i hope to see soon things like koenigsegg's freevalve or who knows maybe triflux.
Incredible piece of engineering
I'm afraid to hear the WEIGHT of that configuration
not heavier than a 3.0 v6
The car itself is apparently 5,100 pounds per the video. I'd bet that the 2.0 engine + turbo + supercharger + electric motor + lithium battery outweighs a 3.0 V6.
Justin i found the exact car on the volvo website and it weighs 4135 pounds not 5100
With or without the electric plug-in option?
He said the XC90 , not S90 i think there's a confusion there guys
Fascinating but complex. A single electric motor would be simpler. Great video as always.
I would never ever think of Volvo as a luxury brand or as something worth buying. They will always be an old people brand or heavy machinery to me. Plus now they’re owned by China so just like jaguar and Land Rover, their prices and luxury went up but their actual quality and longevity has gone down. You can’t pour gravel into the cylinders and drive with it like that anymore, unlike some historically tough older models.
If you want good low end torque, fuel efficiency and reliability, you just need some basic designs. Like small turbos, narrow cylinders and some strong components. You’ll get an engine with plenty of low end torque, a flat power band and if you don’t have a ton of displacement and weight you’ll get good mileage.
Ben G - You've just described everything a Diesel is . . . and why they're safer in an accident.
But you can’t pour gravel into their diesels anymore now can you?
And Incase anyone is confused by my comment, Land Rover and Jaguar aren’t owned by China, they’re owned by TATA motors which is Indian. Which isn’t any better
You made a lot of claims without any fact to back it up. This new Volvo's quality is much better than those old ones produced by Ford. I just don't get why anyone is so obsessed with reliability, I bought a 2018 XC90 T6 Inscription, fully loaded at 73K MSRP, and bought an extended warranty that covers 8 years/100K for 2700 bucks. So even the car worth 0 at the end of 8 year, I'm out less than 10K a year for this car. There are many people like me so there is a big market for luxury vehicles. Also those reliable old models are just not as safe as new vehicles, I value safety, handling, quality and power over reliability.
Shuo Wang Define quality
The geek side of me was all ears. The tech going into engines these days is exquisite
The T8 engine design is really sophisticated. Hopefully. The 4 cylinder motor can handle all these performance enhancements added to it. Would be nice to see the long-term reliability of the T8 engine
How did it hold up?
130k km on mine and it’s running like new
I was excited to hear you mention Wards - I work there.
Talking about frame can you please make it 60FPS
Smaller supercharger pulley(maybe bigger supercharger), bigger turbo, aftermarket boost control, better/bigger intake manifold, injectors and fuel rails. It would be insane
Eaton M90 with a 2.8 inch pulley that made 13 lbs on its own in my old 98 Pontiac Grand Prix GTP pace car... Lol was a ton of fun with around 400 HP to the front wheels only haha
MEH i miss the *GOOD OLD N/A ENGINES WITH HIGH REVS AND STICK SHIFT*
ِ ِ and not only You.
Yeah, but get with the times. The future is now 😜 I’m impressed with these applications.
I am with you - and they'd last a lifetime (literally!).
The future is now, old man.
Draviator no they wouldn't, you all were just less informed.
Thank you very much for your description. I have a new Volvo XC60 with T8 and find your explanation very helpful and understandable for something I find very complex.
What happened to the air tank boost system?
error079 you mean PowerPulse? Thats only on the diesel versions.
With an partly eletric car, you can eliminate the need for a turbocharer air compressor (that was used to aid the supercharger early on by letting the Turbo swool up early, effectivly using both at the same time). But with a Hybrid car, the throttle respone is instantaeous. This combined with an intant power boost from the supercharger and boom, you've gotten rid of the need for the air compressor. Sure you could keep it in if you wanted, but thats just one more complicated system that will require maintanence down the road.
Clayton Spencer explain the v60 hybrid? It has double turbos and electric motor
So?? Where does he say that you cant have turbos and electric motors? He said that you don't need an air compressor.. Which the V60 hybrid doesn't have.
Its absolutely powerful..
I drove it it has soo much power
What about the fuel efficiency? What sort of MPG do these engines get?
The T5 gets 24 mpg city, 34 mpg highway. The T6 gets 22 city, 31 highway
electric motors poison the earth. Have you seen where they harvest the materials?
I know this is an old video, but the T6’s have proved to have very few issues since it’s introduction. Some T5’s had oil consumption issues for a few years, but the T6’s are still functioning perfectly well.
Proper maintenance is obviously key, but I have yet to hear from any other T6 owner that they’ve had a turbo or supercharger go bad. Even if they do, they’re both in very easy to reach spots. Not nearly as complex as you’d expect. As with any euro car, I’m expecting to do some sort of major maintenance when plastics eventually go bad, but 100k miles and 6 years have gone by and mine is still running like a top
Volvo is love, Volvo is life.
And......................... then it breaks!
ErwinSchrodinger64 Volvo's are pretty reliable, especially the 240's and 740's with their redblock engines.
Martin van Weperen Of course a 240 and 740 is reliable, but without knowing for sure i can assume newer volvos wont last long without expensive maintainance, volvo is boring and out of character these days if you ask me...
ErwinSchrodinger64
My 2005 V70 D5 has never let me down, had it 5 years now, the only issue in all that time has been a dodgy abs ecu module, rebuilt for £195 plus £150 fitting, don't be brainwashed by all the fake reliability reports on here !! spread by Audi/BMW fanboys !!!!!!!!!
Great example for the reaction time! I was aware that thats quick but now I have a conatation. Thanks
This is an engine meant for wowing new car buyers. This engine will not last without having copious amounts of money thrown at it, be it from the warranty or from the unlucky SOB that bought it without a warranty.
It's a Volvo engine. It will have no difficulty lasting as it's far more overbuilt than you think... you can probably push the engine to >500HP without changing internals or even reducing service life.
It will need quality oil and more frequent spark plug changes, but that's it. Direct injection eliminates most risk of predetonation and knock killing the engine (as you don't have an air-fuel charge, only air, then the fuel injects when it's time to ignite).
The supercharger is oiled by the engine (most likely - I haven't checked - but Volvo is pretty aggressive with their lubrication) and will usually be clutched to the off state - only coming on under heavier acceleration. The wastegate is left bleeding exhaust so that the turbo only begins a good spool around 3,200 RPM - very late by Volvo's standards, but very good for fuel economy and reliability - so not even the turbo works hard.
Superchargers last according to their lubrication and design. The one here is always getting fresh oil and is usually going to not be doing any work at all. On an engine with 200,000 miles, even with someone with a lead foot, the supercharger will likely only be engaged for 1/10th of that time - likely even less, since it is disengaged for cruise, coasting, light throttle, or high RPM... The clutch and the bypass valve are the only things that might prove to be issues, but these types of parts already exist and have a strong track record of reliability.
You dont really know what volvo is
Citation needed
Volvo isn't an American car. It's better than that.
People only remember the old box volvos from decades ago which did last a long time, its telling that you don't see many newer gen "old" volvos still on the road.
Very good video. I would surely ditch all this complexity and drive a RWD 240.
Car manufacturers: What if we can add more and more stuff which can fail in any moment and customers have to pay for it?
Karol klocolus On new Cars if you buy, there is a 5 year guarantee. So what?
This is why all cars will be electric soon. Electric motors are a mature, 200 year old technology. We've worked the kinks out at this point.
Josh Bobst you have your dellusions
Georgios Vallianatos what about after the 5 years is up?
Based on the way a lot of Model S's seem to be suffering from drivetrain failures even with barely any drivetrain, I'll stay with a proven reliable designs over theoretically reliable designs.
That is truly a marvel of engineering
Jesus Christ... Overengeneering much?
Shockwave Shockwave every new engine is "over engineered" than the previous one. Thats how you make progress
D Jay T I disagree. This isn’t really over engineered in my opinion, as the individual components are still rather simple, their interactions are complex, but not overly so as far as I’m concerned.
Shockwave, 8 cylinders, holey carb on top and 3 speed auto, that would be a thing, wouldnt it ;)
I've got old 940 Ti manual, 1L:7km, and I am happy with it.......
*It's supercharged, turbocharged, electric, and will explode in 5 years.* Good luck finding a mechanic that wants to work on this 8 years down the line.
sdlausen I’d imagine if that’s bad, the mechanics will be lining up to work on it since they can charge by the hour.
More like the wrecking yard at that point, that's the reality when labor hours total a car. You can line up, but no ones paying, because its a disposable car once off lease and princess returns her car.
Well manufacturer will definitely wants the car to last the max 5 years.. so u will have to buy a new model then or they'll be out of business.
When you mentioned that Volvo didn't stop with just super & turbo charging the first thing that came to mind was nitrous.
A volvo with a bottle in the trunk.
Now that would get them some awards.
Love your videos!!!😊💐💕💕❤️
From India!!!😊😎😎😎
very Cool Video! i began Wrenching as a Teenager on 1970s Volvos and have always wondered how they changed over the years not suprisingly they are still Engineered Awesome Mechanically as they were in the Automotive engines and their Marine Division years ago i’m a big fan of Turbocharging and Supercharging and from what you explained and what i’ve read it sounds like the XC 90 is something i may be interested in purchasing i recall that a few years ago they did not meet my Towing Capacity Requirements and i had to Pony Up on buying A American made Adually DeiselTurbo Charged Truck that other than the high price Tag and lower FuelEconomy than Advertised i’ve been quite happy with for many years of good service overall
Funny thing is it isn't that fuel efficient and not all that powerful either neither is it all that light. Simple is almost always better.
This is amazing... until warranty runs out...
But 15 years later this will be a beast on the track.
*.. AND ALSO BREAKS ALL THE TIME*
You must stop calling unreliable engines 'The best engines' just because *in theory* they are!
BrabusBandit Is there proof that its unreliable or are you saying that due to the complexity of the engine. I’m genuinely asking because people in the comments say anything based on any given common, unmediated grounds such as simple = unreliable.
How do you know it isn't reliable? People make claims but never back it up with any sources/data. I like talking about cool technology, and will continue to!
Dolton Collins Been watching Matt Farah's podcast on 'thesmokingtyre', he's a huge car reviewer. And his press car had a tonne of issues including engine related. His friends have had issues with the engine and even his mum who has and XC90 with a super and turbo charged engine. So no guess work here!
Engineering Explained I understand that, and the technologies are cool! But I reckon they're only cool if they work. As described above a number of people have had issues which is a shame. I also understand there is a lot of key-board worriers who'll just say its rubbish because of brand preference without any data, but as mentioned.. People are having reliability issues!
I'm sure if you were to ask Matt Farah he too would agree that three anecdotes do not make a trend. I'm not saying the engine is or is not reliable, but a small pool of anecdotes is not a great thing to base your decision on.
Love this series man keep it going! Do the technical differences between the n55 and b58 from bmw.
Dear all that is unholy, it must break. It will break. It will drain your wallet. Feel sorry for the suckers who attempt to tune this engine for more horsepower.
Do you think there’s a big tuning community amongst S90 owners? I highly doubt that.
Absolutely not! That's my point. The cost to tune such an engine would be extraordinary expensive. Then there's an issue with reliability long term.
Polestar makes one with 415 hp and 500ft-lb of torque..
..The people that would buy this car are most likely baby boomers and soccer moms. Not exactly tuner types.
I'm sure the engine will be just as reliable as its past counterparts, its the transmission I'm worried about.
Why tune a turbo engine in the first place? That is just overboosting the factory specced pressure on which the engine is made for.
An engineering marvel, yes it is. But is it necessary or will it be reliable? It's overly complex & I'm surprised you skipped that aspect in your review.
Having sat through the Volvo UK launch of the new engine architecture (they launched the D4 here as the first one), the diesel and petrol engines also share a lot of the basic structural design. Obviously different heads and slightly beefier block for the derv but they were keen to stress this was a ‘single engine architecture’.
Volvo make the best engines. I have Volvo. t8 xc90 is best car,
tootingbskaevolo those old engines where one of the best especially the v6 and v8. These new ones are too complicated with abysmal real world efficiency.
Great explanation: how does the supercharger switch on or off? What causes the clutch to engage or disengage? Is the supercharger engagement/disengagement point adjustable and how?
No manua,l no care.
Questchaun 1. You're going to have a hard time buying new cars then
2. Do a little research, a manual is coming...
Got a T8 and it is quick, but there is alot of power going through the front wheels. I just feel that a more rear wheel drive emphasis would make for a better drive.
this whole 3 engine system seems sooo reliable
i love the way they joined the super charger, turbo charger and the electric motor all in one, It's down right amazing ! volvo, really pulled out all the stops and thought about everything. but the real question that comes to mind is fuel economy? how much fuel will this engine take? fuel prices go up and down like there no tomorrow. So, how would that take roll in all this ?
Thanks Jason for another excellent presentation. This Volvo's engine, however, is ridiculously complicated and I'm not sure why the award... the weight of the car was too much for a 2 litre, 4 cylinder engine so they started adding up all that? Quite silly in my view... there are other options out there to move that huge SUV more efficient than this adding up engine. Definitely not the car of the future and for the common folk. Thanks again for your excellent work and for sharing your hard worked knowledge with us!
BMW has a similar setup in their 225xe except they use a small variable pitch turbo instead of the supercharger, it spools up from 1200 rpm, then a bigger fixed turbo and an 80kw motor on the rear axle. 225hp from a 1.5lt 3 cylinder engine!
I suggest looking at the award winning N54 and N55. Honestly they're some of the best overall engines I've experienced.
Awesome explanation. Complicated engine... amazing results.
Great video, I enjoy that the engine choices for these videos are newer engines, how many 2jz and rb engine videos can you watch right?
you make me love my Volvo more, thanks for detailed explanation
Volvo t6 stock is fun and enough to satisfy most
With the polestar upgrade !!!
Ooh la la!
Another great video. Thanks again. No worries for the sound, but thanks for being honest.
And what have Volvo done is save on money and space, so that they can fit this in more vehicles, like big SUV's and small family cars like the V40 with it's T3 engine, which is the same as the T4, but less software tuning. And the T4 is the same as the T5, without the some more tuning. This saves on engineering, testing and others. And this is for the newest engine codes, as the old ones were different. The T3 was 1,6l, T4 was 1,6l 4 cyl, the T5 was 2l but 5 cyl. the T4 got 2.0l 4 cyl, and the T3 too. So a bit confusing over a 10 year period. Mainly, the difference is in refinement, as a 4cyl engine producing horsepower of a 6 cyl engine. It feels different. The 6cyl 3.0l engines of the germans are more quiet and refined, they feel smoother. But hey, Kudos for Volvo, for applying tech to achieve this.
this guy just shoots the facts no mindless jibber jabber.
Can you please make a video about Fandt "Vario " drivetrain - i mean vario transmission but also 4wd from fendt. Its quite interresting how it works.
I will say although the engine is complex and many worry about cost to repair, Volvo has a lifetime warranty on any part the customer pays to replace... So if your super charger goes out and you pay to replace it your covered for life....
Hey, Jason ! So what if the sound wasn't 100% , if there was "too much this" or "too little that" !! I enjoyed it A LOT ! BTW, I always enjoy when you go into your "white board mode",. It's very instructive and you have the gift of making things very simple and interesting. Keep up the good work !! :)
That's like being on ,a powerlifter a sprinter, and a good husband. Simply amazing.
You should do a video comparing running an old V8 car Vs. changing your car every few years for a newer model. Would be good to see (on average mileage) what would be best cost wise, most hassle, most damaging to the environment etc.
