this! with inline 6 you are forced into a rwd platform. and since those are dying out, most use v6. and if you use it mainly in fwd applications you can go VR like VW/Audi to save even more space.

@Tehsheeeep because they use the V8 factory for manufacturing engine blocks they just cut 2 of the cylinders it's cheap because for inline you should build a whole new factory, second reason is v6 is more compact and lightweight which are the only pros that V6 has
Yeah the best way to show off an engine in a video is to play the engine and exhaust noise. Music usually ruins car videos, only works well in narrative presentation situations
You don't actually touch on the REAL reason. Other makers are trying to maximize practicality, needing a smaller engine bay and better packaging, or, trying to maximize raw performance... which comes in part by saving weight, which you can do by saving space, and again having better packaging. BMW is nearly alone (well, along with Gordon Murray?) in making cars where the raw performance numbers aren't as important as the feel of the car. And straight-6's are great for feel. Drivers don't CARE if the 330 has a bit less cabin space than the equivalent Toyota, the extra smoothness wins the BMW buyer over. Same story, drivers don't CARE if the E46 M3 had a longer quarter-mile time than the equivalent Mercedes, again, the driving feel was more important. I've been a lucky guy: MkIV Supra TT, E39 BMW, the first edition of the R35, and an F430. So straight-6, cross-crank V-8 (like American V-8s, great rumble), high-tech V-6, and a flat-plane V-8 screamer. I'd rank the engine feel and sound richness probably: best feel straight-6, best sound cross-crank V-8, and the V-6 and flat-plane V-8 last. Note the Ferrari sounds great due to the high redline and loud, sonorous exhaust, but the basic engine note isn't that beautiful. And theV-6 R-35 always sounds like it's playing two notes at once, an octave and a half apart. The BMW V-8 growled like a grizzly, while the Supra hums like a turbine. I still drive the other two but when I sold the R35 I never missed it, really, and after selling the Supra, I miss it hugely.
V6 engines are the ideal configuration if a car manufacturer wants to install a 6 cylinder engine in a front wheel drive car. In a rear wheel drive car and front engine, a straight 6 is the best configuration. Considering both Ferrari and McLaren have a V6 mid engine car, then that must be the ideal engine for that configuration. There is no such thing as the perfect vehicle. Every vehicle is subject to some compromise and for the majority of brands, cost is the biggest factor in determining its characteristics.
Have you tried Busso V6 or Maserati V8? How do you like these engines compared to these you mentioned? For example for me Busso is not so smooth like BMW's I6, but is more alive, beautifully screaming in the end and I prefer this to be honest 😎
@@catalinxnecula I wouldn't know, I haven't listened to any MB V8's since like 2000, when my M5 blew them away. I've been driving the same sedan since 2000 so I'm not likely to change soon.
Between 1986 and 1992ish, my dad had a '86 320I LE with a 2.0L straight six. He still talks glory about that engine, and he still kicks himself for selling it, 32 years later!
@@DabDabGoose that's exactly why BMW pushes their engines so deep in the engine bay with most of the weight behind the front axles. BMWs have perfect 50/50 weight distribution. The front engine anchor design you're talking about is Audi
I absolutely love my Volvo S60 Polestar with a transverse mounted 3.0ltr turbo inline 6 that pumps out 258kw (350hp) & 500Nm of torque and is absolutely buttery smooth.
60 degree V6s are perfectly balanced, as are 60 degree V12s. GM had a 2.8L 60 degree V6 that was expanded to 3.1L, very smooth engines. There were specially made aluminum race versions of those engines.
@@3ducsthere is NO V6 configuration that is “perfectly balanced”, as they have inherent primary and secondary imbalances. The manufacturers include balance shafts (adding weight and complexity) to stop the motor from shaking itself apart. In-line 6’s do not need balance shafts.
@@clonetrooper576they struggle from cheap plastic timing chain guides as every bmw sadly. M50 and m30 is way more reliable then anything bmw has made the last 25 years
you should look at the Ford Barra i6 - was based on a block of a pushrod engine first built in the 60's and evolved into a Twin cam 4L variable timing beast by the 2000's with turbo versions creating circa 300kw out of the factory in performance configurations. After market guy are getting 800hp with stock internals!
Thanks for the nice comments - and yes, I was very surprised to hear that BMW looks at V6s. The explanation given was "we can't NOT look to see if there's a better alternative." Maybe that's how the company threw away so much of the DNA that made it the "Ultimate Driving Machine?" Sounded to me, then and now, more like an identity crisis than engineering curiosity. But I digress...
I would love to see BMW make a compact 3.3 liter V12 based on their 1.6 liter inline 6 cylinder motorcycle engine, then put it in something small and agile like an M1 or a Mini Cooper. I bet that would sound amazing going through a tunnel.
McLaren, BMW and Ricardo have a Engine Development Partnership since 2017. So not really surprise to hear that they worked together on it, when there is a Partnership for that in place for more than 7 years now. 😀
You touched on most of the points and a lot of the comments have addressed some additional ones as well. One thing I haven't seen touched on is modern engines are commonly turbocharged. The plumbing on an inline-6 engine is far far simpler than compared to a V engine. Again reducing complexity.
Inline 6 ain't all Sunshine and rainbows. There's this thing called torsional rigidity and as engines get bigger, it gets worse. Specially long vibey cranks and skinny long blocks. GM Atlas 4.2L and Ford Barra 4.0L come to mind.
Somebody knows more little things. Yes, torsional rigidity is a problem (micron level), and having 7 crankshaft support doesn’t help. On the i6, there is also the last one cilinder hotter than the 1st one who receives a fresher water from the water cooler. The V6 has a more rigid crankshaft because is shorter, the heat (joules) is divided by 2 heads as well and despite not being a natural balanced as the i6 has, one bank counterweights the other one. At last, the i6 is more cheap to manufacture than the V6
@@joseteixeira5900 Cylinder temperature is fixable by correct design of water passages. The i6 crank needs to be more substantial than the V6 crank to reduce torsional oscillation, but against that is the weight reduction due to the total length of the i6 being less than the total length of the two V6 rows. Then there's the reduction in cooling problems due to having more room for the exhaust (and turbo if fitted). The reasons for going V6 are basically to make for a shorter front end and a bigger crumple zone.
Don't forget for the McLaren, they made the v 120 degrees, which sits much flatter more likely resembles a flat 6 than it does a V It's prone to fewer vibrations than the V6s we see on the road. I think BMW would say that McLaren's v6 would measure up to their standards performance and balance, but it would just very impractical to make borderline boxer 6 for a front engine vehicle.
I love my BMW I6's, but plugs isn’t the best example anymore. Took me at least 4 hours on my S55 to take out airboxes, cross braces, covers, intake pipes etc etc etc to get to them. And then re-assemble.
Replacing a cylinder head cover on a modern BMW 6 is a PITA because it hits the firewall. Replacing a clutch is almost always an engine out job because the engine is so far back you can't get to the bolts to disconnect it from the gearbox. Most V6s are easier to work on.
In 2024, most engines can make massive power from many different manufacturers. Plus the B58 can reach around 600-700 hp before it needs some pretty decent mods to go further.. that's in line with most other modern engines, not really the exception
@zachdebuhr6347 most v6 engines stop at 500-600 because they can't handle as much torque like a inline 6 can. I own R35 GTR and compared to my newly bought manual b58 supra, supra can hold more torque but GTR will put down power to the ground like nobody's business even in the rain
@RichardHarrold1991 More cylinders always means more friction, same for higher revs for their more economically minded cars, I3 and I4 are actually a better choice. Especially if you want a torquey car.
@@zibingotaeam3716 the friction is more a product of the cumulative cylinder circumference, so for the K1600 that's 1357.1682mm, versus 1030.44239 for the B48B16. BUT turbocharged versus naturally-aspirated - hotter, higher combustion pressures, friction goes up exponentially with that. And with a daily driver, throttle response is more important than peak torque, and those turbo units are horribly laggy.
The E34 M5 has to be one of the best looking cars BMW have ever produced. As for the I6 - it's an emotional thing, there's nothing quite like driving an I6 on song, everything just feels perfect.
The end of production Evora, I think it's the GT400s or something like that, the one with the carbon fibre engine lid, it just sounds incredible. And it's a Camry engine. That noise with Toyota reliability and servicing must be the best deal in the car world. If I had the choice, I'd swap my S54 for that engine.
Toyota powered. Same engine that’s in the family minivan. It’s a silky smooth v6, every time I drive it I think about how nice it must be in an Evora lol
I clicked this video because in my current collection of random vehicles I found too interesting to not purchase on the spot, I have the following power plants: a single cylinder, a v-twin, a v8, and two v6 engines. And funny enough the V6's I own are the ones that get the most use of any vehicle I've ever owned. Yet they are total opposites of the spectrum, one is a massive displacement high torque but low horse power that runs at low rpms ( makes all its power from 2000 - 3000 rpms. ) this engine runs about as smoothly as a washing machine on spin cycle down a flight of stairs, BUT has about 720,000km on the clock and still runs great. The second engine, is a smaller displacement high horse power, low torque engine that makes all of its power between 6800 - 7500 rpms. And this engine runs so smooth, that with noise in the background I've actually mistaken the car as being shut off on more than one occasion and attempted to start it when it was already running lol (oops) Anyway, they are unique thats for sure. One sounds like a farm tractor, the other sounds like a Lamborghini Gallardo straight piped. All I know, is the miles don't lie.. I drive them a lot.
I've not really thought about it before until watching this but both my vehicles have inline sixes, a 1fz-fe 4.5 litre twin cam and a 7mgte 3.0 litre turbo twin cam, both very very smooth and torquey Toyota engines, this is a very interesting subject for a video, many thanks 😊
Funnily enough, dodge’s replacement for their V8 hemi engine lineup will be comprised of their newly-developed in-line 6 engines. Mercedes started using in-line 6 engines about 8 years ago, and Mazda started using them last year when they released the CX-90 platform. The in-line 6 is genuinely making a comeback.
Couldn't help but notice that wrist band. Proudly KE Back to engines, I guess the inlines have better balance and easier to work on (maintenance) as well as heat dissipation
Probably the only major difference between i6 and V6 which has to do anything with torque is the length of the crankshaft. Are you really suggesting that for this reason only, i6 equipped cars have noticeably higher torque by feel? Well that stinks...
Oh yeah, that Nissan GTR engine was clearly lacking in torque wasn't it? One of the greatest engines ever made? The greatest tuner car ever made to? And its a V6? Who woulda thought it?
You know nothing if you think an inline 6 makes more torque than a V6 just because of the cylinder layout. Gm and Ford V6 engines make much more torque NA vs NA, its easier to make a higher displacement V6 and still be compact than an inline.
I think I’m one of the few petrolheads who will argue that the S38 3.8 straight six is a better engine than the S54. More power and torque. The original block found in the M1 was capable of 800bhp with a turbo.
I have always loved BMW in-line 6 engines. Owned a few of them over the years and they are smooooooth ! I now have a 370Z Nismo and its V6 is very different. Ticks over with a V8 sounding burble and revs to 7500 with an angry growl. Both configurations have their place IMHO.
A tech was doing something on a 19-20 4 series that had had like stage 2 upgrades. I was in the back seat listening for a noise. That car was SCARY fast. That B58 is no joke. I was always partial to the N55.
So nice to see the E34 getting some screen time. I've had my 1996 E34 Touring for 3 years now and adore it and it's M50TU engine. Silky smooth, sounds amazing and actually has surprising performance being a 2L. For me its the best era of BMW
I like to imagine that after those findings, they thought it'd be better to artificially downgrade the I-6 to V-6 standards, and when the market is susceptible to that strat, have the customer pay a subscription to bump it up to the actual standards' realization.
My dad bought a 66’ E type new. I grew up infected with the sound he created on the back roads with that wonderful car. I’ve ever since been a lover of good cars with character. I could never afford to buy an E type, if I could manage it, it’s too far too valuable to wring out as my dad did. I bought an E46 M3 and loved it. At the time, 2013ish, it was affordable performance that I don’t regret buying and so enjoying that straight 6 scream when she’s pushed hard. Yet compliantly graceful around suburbia.
Drivetribe: It is therefore, imperative for you to go to BMW and ask to see those engines stored away. I want to see it, the world wants to see it. Thumbs up if you agree
One of the I6s not mentioned is the one in the k1600 and if bmw didn't go for a v or flat 6 for their comfy 2 wheeler it just shows they're wedded to their "iconic" format
I had never driven a car with an inline 6 until about a year ago when I bought an M240i with the B58. Definitely the smoothest, most powerful engine I've ever experienced.
Tho a rumor is a rumor as soon as you mentioned it I've went to do some digging and there isn't a single piece of media that hints at bmw having anything to do with the artura engine and the onlythings that kinda nullifies that rumor is that the capacities doesn't make sense (1499cc x 2 sandwiched together does not = 2993cc the displacement of the artura but that wouldn't really be a rock solid analogy cuz you never know many manufacturing processes of makin an engine can end up in slight changes of displacement) and every article I've read says that the v6 of the artura is built in house by mclaren themselves in their carbon fiber factory in sheffield, England.
BMW, McLaren and Ricardo developing engines together since their Partnership in 2017. The casting experts came from BMW when they started. It is not really a secret. There are a lot of press releases and so articles available about that. So when all companies officially announced that 7 years ago, why should that be a secret or surprise today? 😀
the McLaren v8 block is essentially a cast off Nissan, maybe look east for an answer. although if you apoxy 2 x 3litre m3 motors of the day together, u get the mac f1 6.05litre v12 engine, so there is some history of bmv consulting to mclaren
@@marcnobel3938 intresting point but my thing is even if the engine is done bmw.. Why would they try to hide it i mean if car companies make cars with engines borrowed or engineered for a specific application on a already existing platform it is most of the time revealed to the public and public information why not this time. Perhaps if that engine is done by bmw in one way or another it has to do with how much significance they had in the engineering and the design itself and if that's the case it wouldn't really make sense since this rumor says that two already existing complete bmw platforms gorilla glued together will still be a project with extreme significance of the companies involvement in the project
@@craig3916 i mean true but the thing is that it was known since day one that mclaren took help from bmw for their engine in the f1 In this case there are little to no hints that bmw had to do anything with the project Also intresting point about nissan Im kinda not tuned in about that how much significance nissan had in development of the mclaren v8s? And if they are actually designed from already existing platforms by anychance?
as a former owner of 14 BMW´s both E34 and E36, the straight 6 from BMW are rock solid and so much smoother than any V6 engine i have ever owned, only the Frankenstein V6 from Alfa Romeo in the 159 comes close to the straight 6 from BMW. 2:30 i never had a issue with a straight 6 engine from BMW in my cars, never. As long oil service was done it was happy. only thing that liked to break was the thermostat. but that was less than 90:- SEK to buy from BMW, about 7-8 USD. Was usually the reason why i could but them cheap, people thought the head was warped. but it was only a bad thermostat. every time. that´s why i could buy 14 of them.
@ the only A8s I’ve worked on are V8 gas and I think not positive V8? Diesel. Not a fan of Audi engineering. But that’s coming from a technicians point of view. Very compact and difficult to work on. Plus they tend to break down more than other European cars.
@@Angl0sax0nknight I mean the W12 engine that put in the A8L (I think) which is why I'm confused when you talked about compactness. Unless it was a one off thing but Audi.

I like how Mike is able to turn his enthusiasm for engines into klicks for the channel. Win win :)
Mercedes has also produced i6s for a very long time too. They had a spell from the mid-1990s when they replaced the i6 with a V6 (so that their new modular V6s and V8s could share components and a production line) before reverting back to i6s.
One of the reasons I have stuck with BMW for so long. Was thinking of getting into the somewhat newer mercedeses a while ago but I didn't really like the engine options. I've had two 3 series and two 7 series and it just so happened that all were inline sixes!
Great Video❤, Can you Please make video on recent inline 6s from bmw especially S58 and B57 Diesel, And recent shift in industry where major automaker like mercedes, hyundai, mazda, GM, stellantis shifted towards Inline 6s
I owned a 2006 M54 powered E46 330ci M-sport convertible for around 10 years and absolutely loved it - that engine is superb (oil leaks aside)! That being said I can't fault my 2012 stage 1 Audi S5 supercharged V6 - it's an absolute beast - sound aside, better than the n/a V8.
N series engines aside with their painful waterpump placement, etc, anything either side of that has to be some of the easiest stuff to come through the workshop. I've had to deal with much worse stuff on Toyotas than the average job on BMWs.
Had an E34 525 as my introduction to BMW straight 6 and I loved that car. Then got an E36 328 which was a flyer. Both engines were phenomenal. Now have a V6 Merc Diesel and if I could only drop a BMW I6 into it……..
I have always loved straight sixes for their bullet proof reliability. The 80's/90's Jeep Cherokees were the bombs. They were in other Jeeps as well. I have a 2005 Lexus IS300 and at 127,000 miles, it still purrs like a kitten.
I have owned and still do several Honda Accords with V6 engines. The Honda engine is great, the 3.0 and the 3.5 litre J motors are very smooth and powerful over the entire rev range. They all have Vtech which comes on strong up top. They also have excellent durability as I have had over 200,000 miles on every one that I have owned. The 60 degree V6 is compact and lighter than any inline 6 and fits in places that the long inline engine cannot. That's why the are great in front wheel drive cars and the can be turned back straight for use in a pickup truck with rear wheel drive. The 60 degree V6 is also well balanced and does not need a balance shaft. It's true that 4 cylinder turbo engines can make more power but they also are short lived and not as smooth as the 60 degree V6's. I think it's a real shame that they are becoming rare in cars because they make any sedan much more quality feeling than any type of 4 cylinder engine. I have owned a BMW 325 e a long time ago and it's 2.7 litre engine was smooth but no smoother than a Honda V6 and the Honda makes way more power.
Simple tradition. V6 engines are more compact and rev higher and are lighter, but they cost a little more to build. They also have a small amount of vibration that inline 6 engines do not have, but the real reason is simple tradition. That's fine, but I still consider BMW cars to be the "Ultimate Leasing Machine", you don't want to own one past the warranty period-
I had an e34 535, the SOHC designed by a Baron. Loved it with a manual box. My favourite engine arrangement by far. Had everything else, flat 4. Straight 4, V6 and V8. Might never bother with V12’s
If my memory serves me correctly back in the 60s someone asked BMW why they didn’t have a v8. The answer given was along the line of a 6 is better balanced, less complicated and if well designed cc per cc as powerful.
BMW sure changed their stance on that when developing the E90 M3. That 4L V8 weighs about 30lbs less than the 3.2L I6 it replaced and, despite having a similar hp per L (less than a 0.4hp/L difference), the geater displacement provided an increase of 84hp.
All engine layouts have their strengths and weaknesses. I've owned BMWs with straight 6s, and they were fantastic. The B58 is a true gem of an engine. The inline 6 has some inherent advantages for sure. There are some phenomenal V6 though. Right now I have a 2024 Nissan Z with the VR30, and it's very impressive. It's far smoother than older Nissan V6s, makes great power, and has reasonable fuel economy. I'm getting roughly the same fuel economy with this car that I did with my 2017 m240i.
The diesel engines were never BMWs strong point, but gasoline i6 are quite reliable, which reliability issues do you mean on which engines? The periphery is something else, like sh.ty water pumps made out of plastic or radiators with plastic parts that end up leaking.
They’re the “ultimate driving experience” and part of that is the feeling you get from a car. And the smooth great sounding I6 beats the trombone V6 anyday.
Thanks for this, does make you wonder certainly. I can vouch for the straight six as I have as a daily a 325 of 1994 with over 173K on clock and still runs like a sewing machine. I have heard of others with over 300k still doing very well!
It’s also to do with the mounting in a longitudinal mounted car. A V6 has more over hang, more likely to understeer. An inline 6 can be pushed further back, increasing chassis balance.
I owned an E90 330i, a 3.0L staight six natural aspirated beauty. Way too much power for my needs but it was a smooth and assertive engine without being the dramatic Alfa Romeo V6 that I knew fairly well with a GTV. I say BMW is wise in keeping their inline 6s instead of V6s, they know how to make them really well.
They can be oil leak nightmares after 150,000 km (if you are lucky) and, from what I have heard, in some of the more recent ones there's too much low rent plastics in the periphery.
Never had a problem with oil leaks, but their sh.tty plastic water pump are a pain in the you know where, I must have had 3 replacements with my N55 engine done in the first 200'000km.
@@doejohn8674 I have the bmw M235 with N55 engine 135000km, the plastic coolant retour hose wil brake over time. Best replace every 100000km or so. Agree they use to much plastic for less weight but there are metal aftermarkt parts for valve cover, charge pipe ,oil filter and so on.
I've had two M54 engines - both leaked oil over the exhaust manifold when the plastic valve cover warped and cracked. It's a known problem. Finally sorted the issue on my current 530i by fitting a Chinese-built Mitzone aluminium cover. £200 and 2000 miles down the road it seems to be working just fine.

@Tehsheeeep because they use the V8 factory for manufacturing engine blocks they just cut 2 of the cylinders it's cheap because for inline you should build a whole new factory, second reason is v6 is more compact and lightweight which are the only pros that V6 has
I love how you put up a compilation of V6's and put an obnoxiously loud music over it, so we cant hear the engines
Yeah the best way to show off an engine in a video is to play the engine and exhaust noise. Music usually ruins car videos, only works well in narrative presentation situations
It's probably for the best of everyone listening
@@mrjohnnyk I think you totally missed locke's inferrence that V6 sound like a two-flush cornlog....and they do.
Unless you are clinically deaf, idk how you can't differentiate the music from the engine. I can hear both just fine.
@@Olabruh So if you were trying to listen to something you wouldn't mind it if someone was blasting loud music in your ears?
You don't actually touch on the REAL reason. Other makers are trying to maximize practicality, needing a smaller engine bay and better packaging, or, trying to maximize raw performance... which comes in part by saving weight, which you can do by saving space, and again having better packaging. BMW is nearly alone (well, along with Gordon Murray?) in making cars where the raw performance numbers aren't as important as the feel of the car. And straight-6's are great for feel. Drivers don't CARE if the 330 has a bit less cabin space than the equivalent Toyota, the extra smoothness wins the BMW buyer over. Same story, drivers don't CARE if the E46 M3 had a longer quarter-mile time than the equivalent Mercedes, again, the driving feel was more important.
I've been a lucky guy: MkIV Supra TT, E39 BMW, the first edition of the R35, and an F430. So straight-6, cross-crank V-8 (like American V-8s, great rumble), high-tech V-6, and a flat-plane V-8 screamer. I'd rank the engine feel and sound richness probably: best feel straight-6, best sound cross-crank V-8, and the V-6 and flat-plane V-8 last. Note the Ferrari sounds great due to the high redline and loud, sonorous exhaust, but the basic engine note isn't that beautiful. And theV-6 R-35 always sounds like it's playing two notes at once, an octave and a half apart. The BMW V-8 growled like a grizzly, while the Supra hums like a turbine. I still drive the other two but when I sold the R35 I never missed it, really, and after selling the Supra, I miss it hugely.
V6 engines are the ideal configuration if a car manufacturer wants to install a 6 cylinder engine in a front wheel drive car. In a rear wheel drive car and front engine, a straight 6 is the best configuration. Considering both Ferrari and McLaren have a V6 mid engine car, then that must be the ideal engine for that configuration.
There is no such thing as the perfect vehicle. Every vehicle is subject to some compromise and for the majority of brands, cost is the biggest factor in determining its characteristics.
Have you tried Busso V6 or Maserati V8? How do you like these engines compared to these you mentioned? For example for me Busso is not so smooth like BMW's I6, but is more alive, beautifully screaming in the end and I prefer this to be honest 😎
and yet an na v8 from mercedes sounds better than everything you mentioned..

The BMW inline 6 is a work of art. We have an e46 330d Msport - even at 20+ years old and with 200k KM on it, the M57n engine is sublime.
Never owned one but family members and friends have had them, M57s are probably the best diesel engine ever built IMO
M57 will outlive us all
The V6 is a packaging thing,it's its only upside.
Not the only upside, in rear wheel driven cars V6's also make for better mass centralization.
and to be fair, its a huge upside. since you can use it in shorter cars and in a transverse layout for fwd platforms.
which is weird considering the effort BMW does to make their cars balanced in weight distribution only to go with a front anchor engine design.
Also weight.
@@DabDabGoose that's exactly why BMW pushes their engines so deep in the engine bay with most of the weight behind the front axles. BMWs have perfect 50/50 weight distribution. The front engine anchor design you're talking about is Audi
I absolutely love my Volvo S60 Polestar with a transverse mounted 3.0ltr turbo inline 6 that pumps out 258kw (350hp) & 500Nm of torque and is absolutely buttery smooth.
See if you love it after 60k miles when it starts dumping fluids into your parking spot.

I have 2 Volvos with over 240,000kms and not a drip.
I have the slightly less powerful s60 t6 with the same 3.0 inline 6 love the way it sounds and pulls.
Inline 6 is naturally balanced. V6s are not.
For now Alfa romeo is a dead brand
60 degree V6s are perfectly balanced, as are 60 degree V12s. GM had a 2.8L 60 degree V6 that was expanded to 3.1L, very smooth engines. There were specially made aluminum race versions of those engines.
@@3ducsthere is NO V6 configuration that is “perfectly balanced”, as they have inherent primary and secondary imbalances. The manufacturers include balance shafts (adding weight and complexity) to stop the motor from shaking itself apart. In-line 6’s do not need balance shafts.
V6s are better for packaging and easier to make a better weight balance for the car.
Yeah cause you can only find them working half the time.

you should look at the Ford Barra i6 - was based on a block of a pushrod engine first built in the 60's and evolved into a Twin cam 4L variable timing beast by the 2000's with turbo versions creating circa 300kw out of the factory in performance configurations. After market guy are getting 800hp with stock internals!
And stock Barra blocks and heads have made 2,000+rwhp (I believe the record is 2,208rwhp), albeit with non-standard rotating assemblies.
Thanks for the nice comments - and yes, I was very surprised to hear that BMW looks at V6s. The explanation given was "we can't NOT look to see if there's a better alternative." Maybe that's how the company threw away so much of the DNA that made it the "Ultimate Driving Machine?" Sounded to me, then and now, more like an identity crisis than engineering curiosity. But I digress...
The dig they had at Mercedes in your article is begging for an 'I told you so' moment down the line...
@@DrivetribeNice video here as usual, how about a video about the comeback of I6 engines (JLR, Mazda, Mercedes, Stellantis) that would be awesome!
@@MrAl2742 and GM took the Opel 2.0 diesel I4 and developed it into the 3.0 Duramax...
I would love to see BMW make a compact 3.3 liter V12 based on their 1.6 liter inline 6 cylinder motorcycle engine, then put it in something small and agile like an M1 or a Mini Cooper. I bet that would sound amazing going through a tunnel.
McLaren, BMW and Ricardo have a Engine Development Partnership since 2017. So not really surprise to hear that they worked together on it, when there is a Partnership for that in place for more than 7 years now. 😀
You touched on most of the points and a lot of the comments have addressed some additional ones as well.
One thing I haven't seen touched on is modern engines are commonly turbocharged. The plumbing on an inline-6 engine is far far simpler than compared to a V engine. Again reducing complexity.
any video with an E34 M5 is a great video in my book.
UNDER RATED COMMENT! I’m all for this!
Inline 6 ain't all Sunshine and rainbows.
There's this thing called torsional rigidity and as engines get bigger, it gets worse. Specially long vibey cranks and skinny long blocks.
GM Atlas 4.2L and Ford Barra 4.0L come to mind.
Somebody knows more little things. Yes, torsional rigidity is a problem (micron level), and having 7 crankshaft support doesn’t help. On the i6, there is also the last one cilinder hotter than the 1st one who receives a fresher water from the water cooler. The V6 has a more rigid crankshaft because is shorter, the heat (joules) is divided by 2 heads as well and despite not being a natural balanced as the i6 has, one bank counterweights the other one. At last, the i6 is more cheap to manufacture than the V6
What about trucks with +12 liter I6 engines?
Considering how much power can be made by a Barra engine, I don't think torsional rigidity is a problem for it.
@@tomnewham1269yep I agree. It's also unbelievably reliable!!
@@joseteixeira5900 Cylinder temperature is fixable by correct design of water passages.
The i6 crank needs to be more substantial than the V6 crank to reduce torsional oscillation, but against that is the weight reduction due to the total length of the i6 being less than the total length of the two V6 rows. Then there's the reduction in cooling problems due to having more room for the exhaust (and turbo if fitted). The reasons for going V6 are basically to make for a shorter front end and a bigger crumple zone.
Don't forget for the McLaren, they made the v 120 degrees, which sits much flatter more likely resembles a flat 6 than it does a V
It's prone to fewer vibrations than the V6s we see on the road. I think BMW would say that McLaren's v6 would measure up to their standards performance and balance, but it would just very impractical to make borderline boxer 6 for a front engine vehicle.
I love my BMW I6's, but plugs isn’t the best example anymore.
Took me at least 4 hours on my S55 to take out airboxes, cross braces, covers, intake pipes etc etc etc to get to them. And then re-assemble.
Replacing a cylinder head cover on a modern BMW 6 is a PITA because it hits the firewall. Replacing a clutch is almost always an engine out job because the engine is so far back you can't get to the bolts to disconnect it from the gearbox.
Most V6s are easier to work on.
Nice video! I love my E89 with the 3.0l straight six. It's amazing how smooth and effortless it runs
Second that, from a fellow E89 N52B30 owner.
The BMW B58 i6 has become the world N1.
A 3.0L i6 capable of 1000 hp.
In 2024, most engines can make massive power from many different manufacturers. Plus the B58 can reach around 600-700 hp before it needs some pretty decent mods to go further.. that's in line with most other modern engines, not really the exception
b58 one of the most tuned and blown engines thesedays

@@Lemingtona-x5g overdo anything and it ll blow.
Most tuners are amateurs.
@zachdebuhr6347 most v6 engines stop at 500-600 because they can't handle as much torque like a inline 6 can. I own R35 GTR and compared to my newly bought manual b58 supra, supra can hold more torque but GTR will put down power to the ground like nobody's business even in the rain

Now if only someone at BMW were to put two of their K1600 I6s together, we could get one last hurrah for the ultimate engine configuration.
That 1650cc I6 could also replace the I3s and I4s in transverse applications.
@RichardHarrold1991 More cylinders always means more friction, same for higher revs
for their more economically minded cars, I3 and I4 are actually a better choice. Especially if you want a torquey car.
@@zibingotaeam3716 the friction is more a product of the cumulative cylinder circumference, so for the K1600 that's 1357.1682mm, versus 1030.44239 for the B48B16. BUT turbocharged versus naturally-aspirated - hotter, higher combustion pressures, friction goes up exponentially with that. And with a daily driver, throttle response is more important than peak torque, and those turbo units are horribly laggy.
@@RichardHarrold1991 yeah, thats what i meant - more cylinders with similar displacement means more swept surface
The E34 M5 has to be one of the best looking cars BMW have ever produced. As for the I6 - it's an emotional thing, there's nothing quite like driving an I6 on song, everything just feels perfect.
One of the greatest sounding V6s is the 2GR-FE in the Lotus Evora, particularly the Evora 400 series from 2015 to 2021, and the Exige series 3.
The end of production Evora, I think it's the GT400s or something like that, the one with the carbon fibre engine lid, it just sounds incredible. And it's a Camry engine. That noise with Toyota reliability and servicing must be the best deal in the car world. If I had the choice, I'd swap my S54 for that engine.

V6 Rav4 brother. Lovely
I clicked this video because in my current collection of random vehicles I found too interesting to not purchase on the spot, I have the following power plants: a single cylinder, a v-twin, a v8, and two v6 engines.
And funny enough the V6's I own are the ones that get the most use of any vehicle I've ever owned.
Yet they are total opposites of the spectrum,
one is a massive displacement high torque but low horse power that runs at low rpms ( makes all its power from 2000 - 3000 rpms. ) this engine runs about as smoothly as a washing machine on spin cycle down a flight of stairs, BUT has about 720,000km on the clock and still runs great.
The second engine, is a smaller displacement high horse power, low torque engine that makes all of its power between 6800 - 7500 rpms. And this engine runs so smooth, that with noise in the background I've actually mistaken the car as being shut off on more than one occasion and attempted to start it when it was already running lol (oops)
Anyway, they are unique thats for sure. One sounds like a farm tractor, the other sounds like a Lamborghini Gallardo straight piped. All I know, is the miles don't lie.. I drive them a lot.
makes taking the intake manifold on an bmw straight six sound so easy lol.
I've not really thought about it before until watching this but both my vehicles have inline sixes, a 1fz-fe 4.5 litre twin cam and a 7mgte 3.0 litre turbo twin cam, both very very smooth and torquey Toyota engines, this is a very interesting subject for a video, many thanks 😊
Not only has BMW not used V sixes, but pretty much nobody else uses inlne sizes, certainly not for mainstream performance cars.
Funnily enough, dodge’s replacement for their V8 hemi engine lineup will be comprised of their newly-developed in-line 6 engines. Mercedes started using in-line 6 engines about 8 years ago, and Mazda started using them last year when they released the CX-90 platform. The in-line 6 is genuinely making a comeback.

The Germans understand Torque. Plain and simple
Edit: GTR fanboys have 0 reading comprehension skills
True
Probably the only major difference between i6 and V6 which has to do anything with torque is the length of the crankshaft. Are you really suggesting that for this reason only, i6 equipped cars have noticeably higher torque by feel? Well that stinks...
Oh yeah, that Nissan GTR engine was clearly lacking in torque wasn't it? One of the greatest engines ever made? The greatest tuner car ever made to? And its a V6? Who woulda thought it?
@@davekennedy6315in the 80's BMW got 1400hp from a 1.5 turbo four in F1. With a completely stock roadcar block.
You know nothing if you think an inline 6 makes more torque than a V6 just because of the cylinder layout. Gm and Ford V6 engines make much more torque NA vs NA, its easier to make a higher displacement V6 and still be compact than an inline.
I think I’m one of the few petrolheads who will argue that the S38 3.8 straight six is a better engine than the S54. More power and torque. The original block found in the M1 was capable of 800bhp with a turbo.

My dad bought a 66’ E type new. I grew up infected with the sound he created on the back roads with that wonderful car. I’ve ever since been a lover of good cars with character.

Tho a rumor is a rumor as soon as you mentioned it I've went to do some digging and there isn't a single piece of media that hints at bmw having anything to do with the artura engine and the onlythings that kinda nullifies that rumor is that the capacities doesn't make sense (1499cc x 2 sandwiched together does not = 2993cc the displacement of the artura but that wouldn't really be a rock solid analogy cuz you never know many manufacturing processes of makin an engine can end up in slight changes of displacement) and every article I've read says that the v6 of the artura is built in house by mclaren themselves in their carbon fiber factory in sheffield, England.
BMW, McLaren and Ricardo developing engines together since their Partnership in 2017. The casting experts came from BMW when they started. It is not really a secret. There are a lot of press releases and so articles available about that. So when all companies officially announced that 7 years ago, why should that be a secret or surprise today? 😀

Mercedes has also produced i6s for a very long time too. They had a spell from the mid-1990s when they replaced the i6 with a V6 (so that their new modular V6s and V8s could share components and a production line) before reverting back to i6s.

I have always loved straight sixes for their bullet proof reliability. The 80's/90's Jeep Cherokees were the bombs. They were in other Jeeps as well. I have a 2005 Lexus IS300 and at 127,000 miles, it still purrs like a kitten.
did you seriously say bmw famously makes their cars easy to work on with a straight face?
I know, right?
I have owned and still do several Honda Accords with V6 engines. The Honda engine is great, the 3.0 and the 3.5 litre J motors are very smooth and powerful over the entire rev range. They all have Vtech which comes on strong up top. They also have excellent durability as I have had over 200,000 miles on every one that I have owned. The 60 degree V6 is compact and lighter than any inline 6 and fits in places that the long inline engine cannot. That's why the are great in front wheel drive cars and the can be turned back straight for use in a pickup truck with rear wheel drive. The 60 degree V6 is also well balanced and does not need a balance shaft. It's true that 4 cylinder turbo engines can make more power but they also are short lived and not as smooth as the 60 degree V6's. I think it's a real shame that they are becoming rare in cars because they make any sedan much more quality feeling than any type of 4 cylinder engine. I have owned a BMW 325 e a long time ago and it's 2.7 litre engine was smooth but no smoother than a Honda V6 and the Honda makes way more power.
Agreed, but changing the Honda/Acura J's rear spark plugs is a very painful exercise. Also, the rubber timing belt is silly on an interference engine.
Inline 6 is more smoother, simpler better for rear wheel drive, provides more torque at lower RPM and they live longer. That’s why
Why would an inline six have more power at low rpm?

Simple tradition. V6 engines are more compact and rev higher and are lighter, but they cost a little more to build. They also have a small amount of vibration that inline 6 engines do not have, but the real reason is simple tradition.
That's fine, but I still consider BMW cars to be the "Ultimate Leasing Machine", you don't want to own one past the warranty period-

What exactly is a proper car? In my opinion it’s something cheap and reliable.
If my memory serves me correctly back in the 60s someone asked BMW why they didn’t have a v8. The answer given was along the line of a 6 is better balanced, less complicated and if well designed cc per cc as powerful.
that's possibly still true!
BMW sure changed their stance on that when developing the E90 M3. That 4L V8 weighs about 30lbs less than the 3.2L I6 it replaced and, despite having a similar hp per L (less than a 0.4hp/L difference), the geater displacement provided an increase of 84hp.
@@lb9gta307 nice, thanks!
Bmw do not make it easy to work on there cars. Coming from someone who works on them every day
I had an E46 with the 2.2i straight 6, and it's true, it was super smooth.
Easy to work on.......,..........if the engine is on the floor.
All engine layouts have their strengths and weaknesses. I've owned BMWs with straight 6s, and they were fantastic. The B58 is a true gem of an engine. The inline 6 has some inherent advantages for sure. There are some phenomenal V6 though. Right now I have a 2024 Nissan Z with the VR30, and it's very impressive. It's far smoother than older Nissan V6s, makes great power, and has reasonable fuel economy. I'm getting roughly the same fuel economy with this car that I did with my 2017 m240i.
If only those BMW engineers would have spent their time making their cars reliable instead of developing engines no one will ever see.
One thing I recently learned is that Ford briefly offered a BMW diesel option in some of the Lincoln models in the early 80’s.
BMW has been building inline 6 engines for decades and STILL can't make a reliable one despite their simplicity. HAHAHA!
Have you owned a bmw inline six engine?
Are you saying the b58 isn’t reliable ? Seriously?
The diesel engines were never BMWs strong point, but gasoline i6 are quite reliable, which reliability issues do you mean on which engines? The periphery is something else, like sh.ty water pumps made out of plastic or radiators with plastic parts that end up leaking.
I just traded my N54 with 208,000 miles in. It put up well with the punishment I gave it for 14 years. It was tuned for 150,000 of those miles.
You have no idea what you’re talking about 😂
They’re the “ultimate driving experience” and part of that is the feeling you get from a car. And the smooth great sounding I6 beats the trombone V6 anyday.
Thanks for this, does make you wonder certainly. I can vouch for the straight six as I have as a daily a 325 of 1994 with over 173K on clock and still runs like a sewing machine.
I have heard of others with over 300k still doing very well!
It’s also to do with the mounting in a longitudinal mounted car. A V6 has more over hang, more likely to understeer. An inline 6 can be pushed further back, increasing chassis balance.
I owned an E90 330i, a 3.0L staight six natural aspirated beauty. Way too much power for my needs but it was a smooth and assertive engine without being the dramatic Alfa Romeo V6 that I knew fairly well with a GTV. I say BMW is wise in keeping their inline 6s instead of V6s, they know how to make them really well.
It’s a real shame that they never drove the black CSL that was sitting there in Everything M3s lot. Or least featured it starting up.
I have a better question.
Why do you hate the idea of finishing off that V10 MX5?
They can be oil leak nightmares after 150,000 km (if you are lucky) and, from what I have heard, in some of the more recent ones there's too much low rent plastics in the periphery.
Never had a problem with oil leaks, but their sh.tty plastic water pump are a pain in the you know where, I must have had 3 replacements with my N55 engine done in the first 200'000km.
@@doejohn8674 I have the bmw M235 with N55 engine 135000km, the plastic coolant retour hose wil brake over time.
Best replace every 100000km or so.
Agree they use to much plastic for less weight but there are metal aftermarkt parts for valve cover, charge pipe ,oil filter and so on.
I've had two M54 engines - both leaked oil over the exhaust manifold when the plastic valve cover warped and cracked. It's a known problem. Finally sorted the issue on my current 530i by fitting a Chinese-built Mitzone aluminium cover. £200 and 2000 miles down the road it seems to be working just fine.
