I disagree on air to air intercooler being more efficient. As a former AC specialist, liquid or water to air is nearly 20 times more efficient heat transfer methods. Air to air coils are mostly used because they are cheaper to produce.
I was caught off guard when he said air to air is the most efficient… air to water has been known as the most efficient for the last 20+ years where is this guy getting his information? Charge air cooling gets better when you add refrigerant cooling to the mix
Not thermal efficiency, but power and complexity efficiency. An air to air cooler has no moving parts and thus little wear and little risk of malfunction, but the thermal efficiency means an air to air cooler would need a significantly larger radiator to provide the same cooling. He mentions the water to air cooler being a lower temp design, which I think is his acknowledgement of water being more thermally efficient.
Also, vapor chamber designs are far more efficient than water transfer designs, as phase change is incredibly thermally efficient, but it is very expensive and prone to damage thus limiting it’s implementation primarily to small electronics.
I agree, water to air is way more consistent across different climates because it's regulated by a thermostat and more efficient compared to air to air which doesn't work as well in hot weather. Water to air is slightly more complex in design while air to air is more common in HD diesel engines like Cummins which is why he probably thinks it's better.
True but I think it comes down to being able to produce one engine that can fit in a larger number of platforms even under 3 liters a straight 6 eats a lot of space under the hood
I just bought a 2024 Rebel with the 5.7. I replaced my Bighorn with the 4.7 I had for 16 years. I don’t plan on towing more than 4500 pounds. I’m happy to get the 5.7 before they are gone.
As a FCA tech, I went through the training for this engine. The engineering was really thought through. Full supported cylinder walls, lots of reinforcement in the block, high pressure pumps located toward the front for better access. Basically an American 2JZ. It's going to be interesting when the tuners get involved and just see how much power the base engine can take before upgrades are required.
@@jhall_79the haters are already in tears as bias TFL just proved it outdid Ford up the toaster. The engine code it threw at idle after the course shows the system works correctly. 100 bucks says it had the same 0w20 for the past 4600 miles the truck has. Oil breaks down.
Only a little over 1,000 miles on my Ram with the SO Hurricane, but so far it is much more responsive than my ‘21 Ram with the Hemi and gets significantly better highway mileage.
I almost purchased a 2021 RAM with the HEMI in it, but decided to wait. I’m on the fence about ordering the 2025 with the Hurricane, but this is good to hear.
@@roman9762 Good to hear! Did you notice that the Hurricane motor becomes more responsive after the first 500-1000 miles? There was another post where someone had mentioned they noticed this.
@@precisionsoundworksstudio It's an extra vehicle and does not get driven daily, only has about 1000 miles on it since this summer. I can't say I have noticed anything like that, but again probably because it's not a daily and hard to pay attention to that.
This is the best and pretty much the only video that explains how this engine was designed. I have a '25 Ram 1500 quad cab tradesman used for towing with this engine. I have had five hemi powered trucks with the same basic configuration. This engine is outstanding, low rpm torque is fantastic and I am looking forward to towing my 29' travel trailer south this winter with this truck. It also has about 100lbs more payload than the '23 hemi truck with 1,843 pounds payload. On a state highway trip with 65 mph speed limit, this engine gave me 26 mpg with a 4x4 truck, better than minivans of 20 years ago.
Inline sixes have been my favorite for more than 40 years, ever since my days as a tech at a BMW dealer. By extension, a V12 is great and silky smooth but who can afford anything they come in?
Did really like my 2015 Ram 5.7L. That engine never gave me an issue. Driving an F-150 2.7L Ecoboost now and really like it as well. I do love a straight 6 though and this looks like a great future option.
I finally got to drive one of these Hurricane engines in a MY25 Ram 1500 SST the other day while I was at the dealer, and I was blown away with how quiet, powerful, and smooth the motor was! My Wife and I have eyeballing the Wagoneers since they came out and while I was at the dealer, I noticed the Grand Wagoneer one we liked and had our eye on was heavily discounted, so we went to go look at it the next day on our day off. We both did like her MY22 Navigator with the high output Ecoboost V6, but this Grand Wagoneer and that high output Hurricane motor are just amazing. Love this video review, as well. I started watching this when it first came out and I knew there was little to nothing that I did not like about it.
Another great video. I like how you’ve explained how you are splitting into good, bad of the SO and a dedicated HO vid. Good job mentioning at the end about emissions driven reasons for the big direction change going with this SST vs more mods to Hemi, especially when S6 has minor improvements to efficiency. I think you nailed it. Cummins and BMW have been using S6 for many years and it works well especially for torque delivery. But it does limit cab and vehicle design for fitting in a long engine. Manufacturers tend to prefer working with V’s as they are more flexible to fit in more platforms. TBH, surprised it fit into Wagoneer. Wonder if other jeeps will get the SST. Long term, this will likely be the Ram 1500 engine platform. But they gotta make it sound better, worst engine noise of all the trucks on the market IMO. And right now it’s a bleeding edge motor… risky… I hope it works well, Stellantis really needs this to be a success. Now to find out what the 2500’s will get for a power plant.
I never thought I would love my new Laramie that much, but man, what a ride!!! Super truck to have. Very powerful, amazing ride, very….very comfortable and I must say, puts GMC and Ford anddddd Tundra in the pocket.
It is cool to see the straight six come back into style. Mercedes, Land Rover/Jaguar, and Mazda all developed new inline six engines in the last 7 years. GM brought over the 3.0l diesel straight six from Europe, and BMW never left the straight six party.
@@Viperman200221 Yeah, it would have been cool if Toyota developed a new inline 6 instead of the new V6 in the tundra and sequoia, but I guess they needed to put it in several different cars and suv's so it couldn't be a long inline 6. I haven't looked recently, but it seemed like the BMW supra engines have been some what reliable, by BMW standards and they can make great power.
@@erikschutzman2402 Yeah. If they did make a new 2J it would only be in the Supra and I know they would lose money. This isn't the first time automakers have used another company's engine. The McLaren F1 comes to mind with the BMW V12!
After working on a 70s full size Jeep Cherokee with an I6, I came to the conclusion that I only want trucks to have I6 motors. So easy to get to everything!!
Excellent video, I am glad to hear the pros of this engine. I currently own a 2025 Ram Laramie with a Hurricane SO. Everything is great, the smoothness and power it delivers. Not so much on its sound, but can be taken care of later with exhaust upgrades. Though mechanically its all great, but what about electronically and software issues. I got a check engine light on at 990 miles, and the techs scanned to show multiple cylinder misfires. I am still waiting for a more thorough inspection soon. Misfires seems to be a thing with this new engine, known from many other Hurricane owners. It seems Stellantis needs to upgrade/update certain software to remedy this misfire issue. That's what I've been hearing from all other Hurricane owners (Ram truck not Jeep). In my case, the misfire hasn't caused any drivability issues, yet. Can you do some research and gather some information regarding this misfire issues that a lot of us Ram Hurricane owners are dealing with. Thank you.
Informative video. Thank you. Looking forward to the other two installments, especially your take on the durability and functionality of the transmission that FCA pairs with this new engine.
I had two hemis and not the and now this Hurricane SO. The Hemi's were good smooth engines but I've had the SO for about 3 months and 3,500 miles now and it has been great, super smooth and great power. MPG is similiar in the City but on the highway I got 24 mpg on a recent road trip which is about 3 mpg better then the hemi did.
It will be interesting to see how carbon/coaking on the intake valves goes without a port injection system. Saw the interview with the Stelantis engineer in the video Getty referenced, but I was not convinced their design is going to be free from this problem as on DI gassers, anyone without port injection system as well gets carbon/gunking on the intake valves. Time will tell I suppose.
A lot of the designs have a built in oil\air separator to eliminate the carbon build up these days. Need to compare a stock hurricane with one that someone installs a oil catch can to see if build up on the valves is different between the two after 50k miles.
@@Cloud30000 If memory serves me correctly, I believe in the interview with the Stelanttis engineer they tried to adjust the cold fresh air intake into the crankcase, I think it was to minimize wet vapor being expelled via the PCV and back into the intake and it may have had a separator under the valve cover already. But again, lab testing & field testing helps, but it's really when you have a few million out on the road with the public and can see what they are looking like when they come in for service at the 50k or 80k mileage point that designs can be validated or need to be improved upon. The motor looks like it has the potential to be a great motor, but time will tell.
As the owner of a 2012 Ram 1500 5.7 hemi it's a little sad to see that engine end production. But at least it looks like the Ram engineers were smart to hold off replacing it until they could assess the experiences of their competition. Starting with a inline six configuration means simplicity and fewer camshafts, gaskets, cam phasers, timing belts, etc. to go wrong. Water intercooling also extends turbo life. And the narrower configuration should make service access easier. I just hope they properly flush metallic debris before installation to avoid a Toyota-sized debacle.
Been driving the standard SST for two months. Extremely quiet, smooth and powerful. I don’t get all the hate. If a 98 Supra inline six can be tuned to push 800 to 1000hp, Ram’s should have no problems pushing 420 and 540hp.
You are not making equal comparison though. The 2jz was overbuilt for it's application and had a very strong block. Even compared to the rb25, the 2jz is way stronger. This is likely within 20% of it's peak power ability before having concerns. Not all inline 6s are the same.
It’s good for 1000 on stock internals actually. I’m this engine exists but stellantis should’ve followed gm and ford with flat plane crank v8 for higher trim models. Europe is finding out the hard way that no one wants a an expensive sports cars with no v8s in it.
No one has enough time on this engine to know what it can do; anyone saying otherwise is full of BS. RAM could not keep offering the Hemi until its cafe numbers come down. Ford had to dump a ton of R&D into the Coyote to bring it inline, in addition to having the 2.7 to balance it out. I don’t know how GM is doing it, but I suspect they are eating the fines until they have a way to replace their V8’s. RAM does not have GM money, and can’t eat those fines.
@@Cloud30000 GM puts 4 cylinders in pretty much every model they make which offsets the V8's. The base engine in the Silverado and Sierra is the 2.7 4 cylinder "Turbomax" which comes in probably half the 1500's they build now. The 5.3 is in a lot of trucks but far less than just a few years ago and the 6.2 is only in the highest trims. Also 2.7 is the only option in Colorado and Canyon.
Back when Toyota designed the 2JZ 20% of Toyota’s profits went directly back into the engineering department of the company. That’s an insane amount of money that engineers had to develop and perfect the 2JZ and other platforms. The only other company in the automotive industry that has that % of engineering cash is Honda. Engineers get blamed on every poor design and lack of quality coming out of Detroit when in many cases they did what they could with the time and money they had to work with. Used to be there were two philosophies in the automotive manufacturing business. One was to keep engineering costs down and fix the issues once the vehicle was sold to the customer and the other was to spend more money on engineering and design and offer shorter warranty on the vehicle. Nowadays I think all manufacturers are pretty much just pushing poor quality vehicles into the market and hoping most will make it until the warranty is over. Even Toyota and Honda are manufacturing vehicles that are an embarrassment to the vehicles that they used to make.
I have a new Grand Wagoner L 4x4 that comes with the 3L HO Hurricane motor and I must say I am very pleased! The motor is extremely thirsty at idle, but in city and highway driving I have gotten close to the rated MPG. We also have a double trailer with WaveRunners, and they are not even noticeable while towing. The MPG while towing weren't affected at all. We previously had a 23 Grand Cherokee L 4x4 with the 3.6 v6, and it did fine, but was very noticeable towing the WaveRunners.
I have always loved the in line 6 cylinder motors...probably because I drive a Peterbuilt. The HO motor will probably stomp the Ford 3.5 motor in towing.
There will be teething pains, as with any new engine. Ford had plenty with the Ecoboost. This will become a worthy standard-bearer engine. Still a shame to lose the V-8 totally.
Ford still has plenty with the Ecoboom engine line. By the time Ford gets one issue fixed they replace it with a new issue. A technician could literally open a shop specializing in Ecoboost equipped Fords and stay busy with them. I’ve worked on my share of them and they are money pits for customers who keep their vehicles long term.
My wife and I are looking into a new rig for her and test drove a grand wagoneer with the 6.4. Holy crap is that thing fun. Stomp on it and the ass end squats down and the thing is fairly quick. The punch of the v8 is awesome. It sold me on a 6.4. It's basically a detuned srt 6.4 from what I gather. 471 hp and 455 torque and a lot of fun. And the sound alone makes me discount the straight 6.
The 5.7 liter is a legendary engine literally see them daily in many Chrysler vehicles but especially Ram trucks a Ram truck isn’t a Ram truck without a fuckin 5.7 liter hemi V8 under the hood. Yeah it’s got garbage exhaust manifolds, and can get lifter ticks, misfiring (it has 16 fricken spark plugs make sure the ignition system is functioning properly!) They are good engines because of the power and torque and they can LAST. It’s one of my favorite engines definitely. Some people shit on the engine because of lifter issues, or the manifold issues but you keep it maintained and don’t be a asshole to it it’ll last you and maybe it wouldn’t get lifter ticks if your lucky I’ve seen over 150k miles 5.7 hemis that sound fantastic no internal noises. I also enjoy working on them they are pretty straight forward It’s the only engine I’d buy in a modern Ram I got 2 with the 5.7 a 5.7 hemi magnum original, and a 2017 with a 5.7 hemi. If I’d buy older than 2003 it be a 5.9 360 obviously
I keep hearing about the power versus the hemi but as someone who tows a 32’ camper that maxes out the payload and towing capacity of my 1500 I can tell you that power is not an issue. The issue that WILL be a problem with these turbo engines is engine breaking. I don’t see it being as good as a v8 engine and when you’re towing stopping and overheating breaks is a bigger deal than a slight bump in power that I didn’t need.
thanks for the video! I went from 6.2 HEMI in Grand Wagoneer to the 3.0 HO in GW and have about 9k miles on it. so far it feels faster to accelerate and so far reliable but like you said basically no more efficient on 93. Its always in boost so no lag that I've noticed, stop start still annoying and gets off the line a little jerky when the engine goes from off to pulling away from a green light. miss that v8 sound though, the 3.0 HO is a deeper note than the 3.0 SO that is in Wagoneer - this engine almost sounds like a tuned import sound
Planning on driving my 2020 Grand Cherokee into the ground. Hopefully by the time i need to replace it, this new Hurricane inline 6 will be sorted out. Still not a fan of direct injection only. Combination DI/ port would have been a smarter choice.
Some minor bolt on mods that engine could sound amazing! They put baffles on intakes to quiet them down. Exhausts have massive mufflers and resonators. Take those out and I bet this engine will sounds sexy!
You want to use a water to air intercooler for shortening the distance between the turbos and the intake manifold, if your goal is avoiding turbo lag on a daily driven vehicle, that's the way to go. For a race car doesn't make sense because you always will have the rpms high and for weight savings, but for the street application is the way to go, especially with a separate coolant system, now the ability to transfer heat to the atmosphere depends on the system quality
You hit a lot of points that are certainly pluses for this new engine. One thing I wish they would have considered was a single turbocharger. It just would have simplified things above and beyond what you highlighted. Maybe the power production couldn't match up to twins.
I have a 2020 f150 with the 2.7 and it has the plastic oil pan. Not sure why ford decided to do that but mine hasn’t leaked so I dunno 🤷🏼♂️. Hopefully it’s good
Great video. I have test driven these in the standard output wagoneer and they are very fast. Much faster than the old 6.4 Hemi in the Grand Wagoneer. I hope Stellantis didn't mess it up and this is a good reliable engine.
I think this engine is very promising, I’ve been waiting for manufacturers to go back to inline 6’s and I think this one has the potential to rival the old 4.0 in terms of longevity and legacy. Even though it’s much more complicated, compared to most other motors this one seems really serviceable and the ability to run on 87 octane opens it up to more remote or fleet operations. Here’s to hoping it holds up well 🤞
My son who recently traded his 2016 Mustang GT for a 2023 BMW X5 plug in hybrid which he really likes flew from CA to help his Mom and sisters family after Helene who live close to Asheville rented a 2025 Ram Rebel with the Hurricane engine. He loves it so much that he's now planning to trade his BMW for a new Ram Rebel.
I’ll stick with my 2020 Ram 1500 Classic Hemi as long as possible. Does everything I need it to without being overly complicated to work on or costly to maintain, and was $32k brand new. Couldn’t even afford to look at a new Ram even if I was interested in the Hurricane I6.
I know no one will believe me but I got my 2019 ram 1500 quad cab v6 for $20,500 out the door right before car prices skyrocketed. I owe $643 on it, will be paid off tomorrow!
It might be a real interesting point to see if Stelantis is still going to be a thing here in the US much longer. They are embroiled with much litigation and investigations her in the US for their business practices.
Their European owners definitely don't seem too interested in the US brands since they are trying to force them to design their vehicles as if they are selling to a European customer.
I probably would have put the intercooler below and in front of the bottom of the radiator. And for you people that say that's stupid, it's done on ALL semi trucks. They are about the same size as the radiator.
Was on the fence over a new 2024 1500 with a 5.7 Hemi or a 2025 with the 3.0L TT. After comparing the two, I ended up purchasing a 2025 1500 Bighorn. It was the obvious choice for a more capable pickup. I'm going to miss the unique sound the 5.7 makes. That and the 6.4 are some of the best sounding engines I've ever heard and had the pleasure of owning. Engineers really did think things through while designing the Hurricane, I trust they made the right decision to move foward as the standard. Stellantis/FCA has been setting the bar for high perfomance engines in North America for over a decade. I doubt they'd slack on the 3.0L straight six and it shows. Or maybe I'm just biased from the 4.0L days. The new truck is a dream to tow with. You don't have to rev out the engine to stay in peak power and is smooth as butter during acceleration. Torque is immediate with out lag. It still feels like I'm dring a V8, minus the sound.
There is anecdotal evidence suggesting higher oil consumption with plasma coated engines from Ford, but I am shocked they did not use forged pistons with this engine running 0ver 20 pounds of boost.
Cann you do a technical comparison between the Hurricane and B58? Everyone always mentions the B58 when talking about the Hurricane, but I've never seen a real comparison.
The H.O is more similar to the S58 while the S.O is closer to the B58.The B58 would strike better because it comes with forged internals and crank from factory unlike the S.O hurricane,while at the same time,the S.O has the advantage of having twins and having more power out of the box unlike the B58(other than the new TU3 B58 that comes as dual PI and DI from factory)top of them both having close compression ratios and etc. The H.O is similar/a bit better than the S58 only because it comes with forged internals unlike the S58 that comes with the same internals as the S63(may have gotten this V8s name wrong)V8 that are known for bending over 700whp(of course people have tested it and have gone over 800+whp with them but that's still risky regardless)along with the H.O also being plasma sprayed similarly to the VR38 and coyote. Main thing is that both are twin turbo but the hurricane has more power out of the box(well, highest hp model atm has 550hp)but the S58 has a lower compression ratio than the H.O while still being not too far off the S58s compression ratio even then.
But, does it sound as good as my 5.7l on cold start? No. 😊 a few things... 1) with the shake up at the top, it sounds like a v8 may be coming back. 2) I don't understand the push from the EPA to go to these turbo 6's that require 91 octane and get the same or worse real world mpg as my 5.7l hemi. All that does is cost me more money at the pump! 3) 100% agree with the inline 6. 4.0l, anyone? Bulletproof. Hopefully they took some notes! Great video as always, thanks for all the great detail.
I have a GDI engine with 90k miles. I installed a catch can at like 15k, but so far there has been no issues that I can attribute to carbon build up on the valves. I really think even without the CC, that most people will not have any significant issues if they perform regular oil changes over a similar period.
It sounds really busy, a little more than I like. The rattle would make me go crazy. I have a Bighorn 1500 eTorque that is very quiet running and has zero vibration.
Ive had 3 reports from people that own them. 1 is happy 2 isn't. The 2 that isn't had issues out the gate. One blew oil all over underneath the truck. Other told me the engine failed on them at 15k. Shop that towed it in said alot of cheap part and shortcuts were taken, especially the 2 turbo. This is why I wait 3 or so years to get a new style engine.
They put the exhaust on the wrong side for a home run. They should have the exhaust on the opposite side so there isn't a crossover of both the exhaust and the fuel. Or have the fuel on the right side for easier fueling at Costco, but the DT rams already have them on the left so...
It's using an open deck, that's gonna add up to big problems before 30k miles. Also the HO model is the engine that comes with a forged crank and connecting rods. The standard has a regular crank and connecting rods
I would absolutely love to hear your thoughts on the 3.0L duramax as well. I'm currently looking for a truck to town a jeep on a trailer, and ive been devouring your towing test videos. Great stuff. Your 5.3l and 6.2l tow tests were great! and the 2.7l turbomax really helped me decide to steer away from that engine for my needs. The 3.0 SST from RAM is on my list of possibilities, as is the 3.0 duramax in a silverado or sierra. Got any diesel mechanic opinions about the 3.0 duramax? Thanks for all the content!
Thank God the manufacturers around the world are going back to inline 6 (BMW never changed-that tells you something), could never get my head around why you would deliberately introduce complexity, plus and more importantly balance, as well as space, modular design (inline 3,4,5,6 cylinder) etc etc. I still love my diesels though. Effortless torque, however I REALLY like THIS engine, which is most unusual for me (very old fart-stick in the mud)!
I just bought a 2025 ram with the hurricane SO, I couldn’t be happier with this new engine, I’m coming from a 2021 Hemi. I’m so sick and tired of the naysayers, both of my trucks were bought with the 3.92 gears, I’m getting 3mpg better truck alone or towing. And this thing will spank a Hemi, from a standing start or rolling.
On the surface it looks good, sounds weird though. Time will tell!! I drove the hurricane for 2 weeks and the thing that bothered me was only 21 psi oil pressure at 70 mph, my 5.7 runs 52 psi at 70 mph
The i6 does have less parts, but those parts are doing twice as much. Does that mean less to fail, or that what remains is now twice as likely to fail?
I bought a new Ram 1500 Big Horn with the hurricane. It'll get up and run but I absolutely hate it for just cruising around and keeping a steady speed. It doesn't get any better gas mileage than my Hemi did. I regret getting rid of my Hemi. I've been a big mopar guy all of my life but if they don't have another v8 out come time I get another truck in 2-3 years I'll be going to a different brand.
I've been getting 19-21 combined MPG consistently with my 5.7L etorque RAM 1500. I've noticed Shell gives me better mileage than most other stations near me. Make sure to use mid grade if you aren't already. Regular brings the mpg way down.
@@BeRyan8923I always told family members & friends that shell’s formula gives better gas mileage especially on the highways. I recently got 24mpg on shell mid grade gas, 2hrs drive with cruise control set @70mph and gears manually selected to +8 to force all V8 cylinders working (hate eco mode).
IF Stellantis had applied the same technologies to the 5.7 it would out perform the I6... twin turbos, Forged Components, Fixing the tick, better oil pump for better flow.... etc... It would be closer in balance than the V6... I could go on and on. It have a better sound as well. They also could have increase batteries and added roof solar chargers and increased fuel tank to be largest of all 1/2 tons and increased towing cap... on and on... would be great to see some after market designers and engineers go after besting the Hurricanes in power and fuel economy for less than Stellantis spent on the Hurricane.
Enjoyed your video, I too had watched the second video you had referred to. I bought a 2025 Ram 1500 with new motor and so far so good. Several comments on a owners forum commenting on a misfire which triggers a "check Engine" light. Had heard an "on line update" is in the works-any info on that ???
I do worry about direct injection, plus where's my dipstick . Plus truck prices, I think I'll keep my 2015 Hemi for a while. Looking forwards to the next videos.
Very good points, they are also major to me. Besides these major points, I am looking forward to the I6 in general, because as he mentioned, the engine design (independent from Dodge) has many advantages, but yes: It's lacking the "balls" from a V8, but therefor it's just smooth.
The fact that the cylinder liner are treated with a specialized process only an OEM has access to, tells me that the engine blocks are throw away because no machine shop will be able to re-bore and hone these. Good job Stelantis.
Well, a gasoline engine with SCR and GPF (gasoline particles filter) will be as complex as a diesel. In that case, I prefer diesel. No knocking problem, no VVT or variable lift, no spark plugs, etc... and during partial and full load, they are more efficient. We have a lot of diesel in my country (Isuzu Dmax, Nissan Frontier, Toyota Hilux, Land Cruiser, Fortuner, Mitsubishi L200, Hyundais, etc...) and they get amazing fuel consumption for their weight. I had a 2007 Hyundai Accent CRDI, and that thing had a fuel consumption, in long trips, of 4.3l/100km in hilly terrain and a 3.7 l/100km as best, with the enjoyable torque that it had (173 lb-ft from a 1.5 liter engine), in city its fuel consumption was 5.8-6 l/100km. A friend has a Toyota Fortuner (3.0 turbo diesel, 1KD-FTV), it gives him 12 l/100km, his son-in-law has a 2011 CRV, the CRV gives 16 l/100km (Nothing wrong with it). So, a heavier 4x4 car vs a crossover, and with better fuel consumption, recipe: diesel . Greetings
I myself can't wait for folks to start tuning these. I'm curious how much boost the spray in liners will hold. I6 engines have always held a spot in my heart.
I still do not understand how all these vehicle giants did not know about the strength and balance of an inline 6. Someone got bought out obviously , because I was 13 when I seen the 2J build and understood the wonder. I am 37 now making 500hp off a rotary that would fit on your 3yr old's table. 6 years later, same engine, same everything. We need to embrace Japan's quality.
But I can’t even check my own oil level. Should I really trust sensors to tell me oil level? Little scary to me. I’m an oil nerd… so this is gonna take a while to get used to an engine with no oil dipstick where I can physically see my oil
A non-issue in my mind. Maybe paying a little extra attention when you do your own oil changes to see if everything matches to what the vehicle says, but after that I bet you’ll forget to worry.
@@ALMX5DP ... until the warning light fails and you don't know you're low on oil until it's too late and wipe out an expensive engine that Ram won't warranty > > > all because some idiot engineer/ bean counter saved a few pennies by removing a dipstick.
@@hmdwn you sound so certain of a failure at the most inopportune time, I presume you also believe if/when that occurs (sensor “failing”) there will be no indication made to the driver? Any foundation for this colorful opinion of yours?
I have owned BMWs with oil sensors. There are several advantages with the upgrade! 1. 99% of drivers do not check their oil ever. 2. If the sensor fails, you will have an error message. 3. Driver will be alerted if oil is low! 4. Sensor works while driving and saves many engines from blowing up due to a rock to the oil pan or an oil cooler system leak. 5. Saves the OEM big time on warranty claims. They can tell if you ran without enough oil. Costs us less not paying for others mistakes. 6. Easier to catch fuel dilution caused by improper fuel injection. What’s not to like? You can still smell the oil fill tube if you possess mad skills and you can determine if there are issues with the oil.
I am curios to know, why the I6 (with Turbos) is less efficient in the city compared to the V8. Surprises me. Is there a logical explanation, or is this probably caused by enforced emission requirements which are choking down the efficiency?
H.O -More hp(510-550hp from factory but is model dependent with hp) -H.O can only take premium(S.O can take reg gas) -Is a I6 -comes DI only unlike the ecoboost coming DI and PI recently -has a closed deck block unlike the ecoboosts open deck block. -comes with forged internals and crank(S.O doesn't have this unfortunately).
Air to water is a large improvement over air to air. Air to air is used more often because it is a simpler system with les moving parts. But air to water is more efficient at cooling the air charge down. Just look at all drag racers makong big power most of them use air to water
What's the compression ratio for the Hurricane? You mentioned Knock, but a NA engine would ideally run at higher a higher compression ratio meaning knock is more important to manage
Let’s hope they do succeed with this new engine . They have failed in the 3.0 Turbo diesel engine with a total nightmare! The 2.4 turbo 4 cylinder also problematic engine. Now water cooling the turbos!! Well will see how long these turbos will last
Hey guys, sorry about the lighting being a little over exposed. My skill set is not working the camera, clearly 😅.
I had to put my sunglasses on to watch this one...😮😅
I have got to see you with the RAM SO version on your towing loop.
Your audience cares about the facts and your opinion. It’s all good
I disagree on air to air intercooler being more efficient. As a former AC specialist, liquid or water to air is nearly 20 times more efficient heat transfer methods. Air to air coils are mostly used because they are cheaper to produce.
I was caught off guard when he said air to air is the most efficient… air to water has been known as the most efficient for the last 20+ years where is this guy getting his information? Charge air cooling gets better when you add refrigerant cooling to the mix
If it was more efficient Merc and BMW would have been air to air too. Air to air is only on lower end brands - full stop.
Not thermal efficiency, but power and complexity efficiency. An air to air cooler has no moving parts and thus little wear and little risk of malfunction, but the thermal efficiency means an air to air cooler would need a significantly larger radiator to provide the same cooling.
He mentions the water to air cooler being a lower temp design, which I think is his acknowledgement of water being more thermally efficient.
Also, vapor chamber designs are far more efficient than water transfer designs, as phase change is incredibly thermally efficient, but it is very expensive and prone to damage thus limiting it’s implementation primarily to small electronics.
I agree, water to air is way more consistent across different climates because it's regulated by a thermostat and more efficient compared to air to air which doesn't work as well in hot weather. Water to air is slightly more complex in design while air to air is more common in HD diesel engines like Cummins which is why he probably thinks it's better.
Sad how Toyota who built some of the most legendary inline-6 engines now seems to be allergic to them.
True but I think it comes down to being able to produce one engine that can fit in a larger number of platforms even under 3 liters a straight 6 eats a lot of space under the hood
@thejosh0100 also inline 6 tends to be a taller engine, toyota likes to design front ends with low hoods.
@@herculesinwyoming cries in Tacoma and tundra
@@herculesinwyomingNo, the new Tacoma and tundra hoods are tall
Same with ford with that 300 straight 6 they had. You couldn’t kill that thing
Phenomenal explanation of this engine. Quickly becoming one of my favorite channels for truck overviews
I just bought a 2024 Rebel with the 5.7. I replaced my Bighorn with the 4.7 I had for 16 years. I don’t plan on towing more than 4500 pounds. I’m happy to get the 5.7 before they are gone.
@@shayjohnson5830yep I have a 2020 5.7 and will get one more before they are gone
Wise choice. I change the oil every 6k-7k kms in my 5.7 and keep the idling time as little as possible, she runs like a charm after 112k.
Stay on top of those oil changes
Great engine, though overkill for the towing application.
Add some biotech lubegard each oil change to keep engine tick away.
Got my Rebel in late March just before they started pumping out the 25’s. Glad I got the 5.7! G/T package has a nice stock exhaust note.
As a FCA tech, I went through the training for this engine.
The engineering was really thought through. Full supported cylinder walls, lots of reinforcement in the block, high pressure pumps located toward the front for better access. Basically an American 2JZ.
It's going to be interesting when the tuners get involved and just see how much power the base engine can take before upgrades are required.
I’m hoping this engine is a solid one, time to silence the haters
@@jhall_79the haters are already in tears as bias TFL just proved it outdid Ford up the toaster. The engine code it threw at idle after the course shows the system works correctly. 100 bucks says it had the same 0w20 for the past 4600 miles the truck has. Oil breaks down.
How much is this vehicle?
@fullbloodedchristian9206 time will tell.
It needed “reinforcement” since it started out as a 122 HP Alpha Romeo 2.2 liter 4 cylinder.
Only a little over 1,000 miles on my Ram with the SO Hurricane, but so far it is much more responsive than my ‘21 Ram with the Hemi and gets significantly better highway mileage.
I almost purchased a 2021 RAM with the HEMI in it, but decided to wait. I’m on the fence about ordering the 2025 with the Hurricane, but this is good to hear.
Same, replaced my 2020 Rebel with Hemi for a 2025 Rebel with I6. So far better in every way.
@@roman9762 Good to hear! Did you notice that the Hurricane motor becomes more responsive after the first 500-1000 miles? There was another post where someone had mentioned they noticed this.
@@precisionsoundworksstudio It's an extra vehicle and does not get driven daily, only has about 1000 miles on it since this summer. I can't say I have noticed anything like that, but again probably because it's not a daily and hard to pay attention to that.
@@roman9762 Great to hear you like it better than the HEMI, though.
This is the best and pretty much the only video that explains how this engine was designed. I have a '25 Ram 1500 quad cab tradesman used for towing with this engine. I have had five hemi powered trucks with the same basic configuration. This engine is outstanding, low rpm torque is fantastic and I am looking forward to towing my 29' travel trailer south this winter with this truck. It also has about 100lbs more payload than the '23 hemi truck with 1,843 pounds payload. On a state highway trip with 65 mph speed limit, this engine gave me 26 mpg with a 4x4 truck, better than minivans of 20 years ago.
Inline sixes have been my favorite for more than 40 years, ever since my days as a tech at a BMW dealer. By extension, a V12 is great and silky smooth but who can afford anything they come in?
Did really like my 2015 Ram 5.7L. That engine never gave me an issue. Driving an F-150 2.7L Ecoboost now and really like it as well. I do love a straight 6 though and this looks like a great future option.
I finally got to drive one of these Hurricane engines in a MY25 Ram 1500 SST the other day while I was at the dealer, and I was blown away with how quiet, powerful, and smooth the motor was! My Wife and I have eyeballing the Wagoneers since they came out and while I was at the dealer, I noticed the Grand Wagoneer one we liked and had our eye on was heavily discounted, so we went to go look at it the next day on our day off. We both did like her MY22 Navigator with the high output Ecoboost V6, but this Grand Wagoneer and that high output Hurricane motor are just amazing. Love this video review, as well. I started watching this when it first came out and I knew there was little to nothing that I did not like about it.
Another great video. I like how you’ve explained how you are splitting into good, bad of the SO and a dedicated HO vid. Good job mentioning at the end about emissions driven reasons for the big direction change going with this SST vs more mods to Hemi, especially when S6 has minor improvements to efficiency. I think you nailed it. Cummins and BMW have been using S6 for many years and it works well especially for torque delivery. But it does limit cab and vehicle design for fitting in a long engine. Manufacturers tend to prefer working with V’s as they are more flexible to fit in more platforms. TBH, surprised it fit into Wagoneer. Wonder if other jeeps will get the SST.
Long term, this will likely be the Ram 1500 engine platform. But they gotta make it sound better, worst engine noise of all the trucks on the market IMO. And right now it’s a bleeding edge motor… risky… I hope it works well, Stellantis really needs this to be a success. Now to find out what the 2500’s will get for a power plant.
Too many people focus on MPG but do not realize that emissions are not the same as MPG; if they were, a Prius would not need a catalytic converter.
I never thought I would love my new Laramie that much, but man, what a ride!!! Super truck to have. Very powerful, amazing ride, very….very comfortable and I must say, puts GMC and Ford anddddd Tundra in the pocket.
It is cool to see the straight six come back into style. Mercedes, Land Rover/Jaguar, and Mazda all developed new inline six engines in the last 7 years. GM brought over the 3.0l diesel straight six from Europe, and BMW never left the straight six party.
It's sad to see Toyota cheaping out and using a BMW straight 6 in the new Supra. It would of been nice if they designed a new age 2J!
@@Viperman200221 Yeah, it would have been cool if Toyota developed a new inline 6 instead of the new V6 in the tundra and sequoia, but I guess they needed to put it in several different cars and suv's so it couldn't be a long inline 6.
I haven't looked recently, but it seemed like the BMW supra engines have been some what reliable, by BMW standards and they can make great power.
@@erikschutzman2402 Yeah. If they did make a new 2J it would only be in the Supra and I know they would lose money. This isn't the first time automakers have used another company's engine. The McLaren F1 comes to mind with the BMW V12!
Sad! That I6 sounds absolutely terrible.
After working on a 70s full size Jeep Cherokee with an I6, I came to the conclusion that I only want trucks to have I6 motors. So easy to get to everything!!
Yeah it ain’t an old straight six from the 70s, much more complicated with alot more sensors and plumbing.
Excellent video, I am glad to hear the pros of this engine. I currently own a 2025 Ram Laramie with a Hurricane SO. Everything is great, the smoothness and power it delivers. Not so much on its sound, but can be taken care of later with exhaust upgrades. Though mechanically its all great, but what about electronically and software issues. I got a check engine light on at 990 miles, and the techs scanned to show multiple cylinder misfires. I am still waiting for a more thorough inspection soon. Misfires seems to be a thing with this new engine, known from many other Hurricane owners. It seems Stellantis needs to upgrade/update certain software to remedy this misfire issue. That's what I've been hearing from all other Hurricane owners (Ram truck not Jeep). In my case, the misfire hasn't caused any drivability issues, yet.
Can you do some research and gather some information regarding this misfire issues that a lot of us Ram Hurricane owners are dealing with. Thank you.
Informative video. Thank you. Looking forward to the other two installments, especially your take on the durability and functionality of the transmission that FCA pairs with this new engine.
I just bought a 2025 1500 longhorn. Still sad I have no hemi but I love Ram. Atleast I still have my 5.7L Durango
Great video! You do a great job in digging deep into the details.
I really enjoy your reviews. Great editing and easy to follow
I had two hemis and not the and now this Hurricane SO. The Hemi's were good smooth engines but I've had the SO for about 3 months and 3,500 miles now and it has been great, super smooth and great power. MPG is similiar in the City but on the highway I got 24 mpg on a recent road trip which is about 3 mpg better then the hemi did.
It will be interesting to see how carbon/coaking on the intake valves goes without a port injection system. Saw the interview with the Stelantis engineer in the video Getty referenced, but I was not convinced their design is going to be free from this problem as on DI gassers, anyone without port injection system as well gets carbon/gunking on the intake valves. Time will tell I suppose.
I have a well tuned 3.5 TT. Lots of bolt ons. I have a special 93 octane tune.
That carbon was what worried me too. Only time will tell!!
And, good luck getting the intake off to walnut blast the valves.
A lot of the designs have a built in oil\air separator to eliminate the carbon build up these days. Need to compare a stock hurricane with one that someone installs a oil catch can to see if build up on the valves is different between the two after 50k miles.
@@Cloud30000 If memory serves me correctly, I believe in the interview with the Stelanttis engineer they tried to adjust the cold fresh air intake into the crankcase, I think it was to minimize wet vapor being expelled via the PCV and back into the intake and it may have had a separator under the valve cover already. But again, lab testing & field testing helps, but it's really when you have a few million out on the road with the public and can see what they are looking like when they come in for service at the 50k or 80k mileage point that designs can be validated or need to be improved upon. The motor looks like it has the potential to be a great motor, but time will tell.
@@jameszeiger8533 this is partly why I'd like it if it where dual Port and direct so it'd be less of a thing to worry about.
In history there have been some great I-6. GM 292 I-6, Ford 300 I-6, Jeep 4.0 I-6.
Great review, I may get a 2025 Rebel with this engine tomorrow, so far most reviews are very positive but your is a more in depth review.
As the owner of a 2012 Ram 1500 5.7 hemi it's a little sad to see that engine end production. But at least it looks like the Ram engineers were smart to hold off replacing it until they could assess the experiences of their competition. Starting with a inline six configuration means simplicity and fewer camshafts, gaskets, cam phasers, timing belts, etc. to go wrong. Water intercooling also extends turbo life. And the narrower configuration should make service access easier. I just hope they properly flush metallic debris before installation to avoid a Toyota-sized debacle.
Wow, the even more complicated than an ecoboost? I don't know man!
Inlines have issues of their own....
@@davidortiz173 Quite the opposite. In-line 6 is the simplest engine architecture.
@@doctordetroit4339Name them please.
Motorcycle engines have used sprayed on liner aluminum cylinders since the 1980's and they work just fine.
Been driving the standard SST for two months. Extremely quiet, smooth and powerful. I don’t get all the hate. If a 98 Supra inline six can be tuned to push 800 to 1000hp, Ram’s should have no problems pushing 420 and 540hp.
You are not making equal comparison though. The 2jz was overbuilt for it's application and had a very strong block. Even compared to the rb25, the 2jz is way stronger. This is likely within 20% of it's peak power ability before having concerns. Not all inline 6s are the same.
It’s good for 1000 on stock internals actually. I’m this engine exists but stellantis should’ve followed gm and ford with flat plane crank v8 for higher trim models. Europe is finding out the hard way that no one wants a an expensive sports cars with no v8s in it.
No one has enough time on this engine to know what it can do; anyone saying otherwise is full of BS.
RAM could not keep offering the Hemi until its cafe numbers come down. Ford had to dump a ton of R&D into the Coyote to bring it inline, in addition to having the 2.7 to balance it out. I don’t know how GM is doing it, but I suspect they are eating the fines until they have a way to replace their V8’s. RAM does not have GM money, and can’t eat those fines.
@@Cloud30000 GM puts 4 cylinders in pretty much every model they make which offsets the V8's. The base engine in the Silverado and Sierra is the 2.7 4 cylinder "Turbomax" which comes in probably half the 1500's they build now. The 5.3 is in a lot of trucks but far less than just a few years ago and the 6.2 is only in the highest trims. Also 2.7 is the only option in Colorado and Canyon.
Back when Toyota designed the 2JZ 20% of Toyota’s profits went directly back into the engineering department of the company. That’s an insane amount of money that engineers had to develop and perfect the 2JZ and other platforms. The only other company in the automotive industry that has that % of engineering cash is Honda.
Engineers get blamed on every poor design and lack of quality coming out of Detroit when in many cases they did what they could with the time and money they had to work with. Used to be there were two philosophies in the automotive manufacturing business. One was to keep engineering costs down and fix the issues once the vehicle was sold to the customer and the other was to spend more money on engineering and design and offer shorter warranty on the vehicle. Nowadays I think all manufacturers are pretty much just pushing poor quality vehicles into the market and hoping most will make it until the warranty is over. Even Toyota and Honda are manufacturing vehicles that are an embarrassment to the vehicles that they used to make.
I have a new Grand Wagoner L 4x4 that comes with the 3L HO Hurricane motor and I must say I am very pleased! The motor is extremely thirsty at idle, but in city and highway driving I have gotten close to the rated MPG. We also have a double trailer with WaveRunners, and they are not even noticeable while towing. The MPG while towing weren't affected at all. We previously had a 23 Grand Cherokee L 4x4 with the 3.6 v6, and it did fine, but was very noticeable towing the WaveRunners.
I hope this engine does really well. I’m a Hemi guy right now and hate to see it go but I’m excited about this new engine.
I have always loved the in line 6 cylinder motors...probably because I drive a Peterbuilt. The HO motor will probably stomp the Ford 3.5 motor in towing.
We will see how well they designed the head and block clamping to prevent blown head gaskets.
Yes design is one thing. real world performance is another! hopefully it holds up.
There will be teething pains, as with any new engine. Ford had plenty with the Ecoboost. This will become a worthy standard-bearer engine. Still a shame to lose the V-8 totally.
Mad max comes to life
Ford still has plenty with the Ecoboom engine line. By the time Ford gets one issue fixed they replace it with a new issue. A technician could literally open a shop specializing in Ecoboost equipped Fords and stay busy with them. I’ve worked on my share of them and they are money pits for customers who keep their vehicles long term.
My wife and I are looking into a new rig for her and test drove a grand wagoneer with the 6.4. Holy crap is that thing fun. Stomp on it and the ass end squats down and the thing is fairly quick. The punch of the v8 is awesome. It sold me on a 6.4. It's basically a detuned srt 6.4 from what I gather. 471 hp and 455 torque and a lot of fun. And the sound alone makes me discount the straight 6.
I am grunting like Tim Allen in Home Improvement reading this. Long live the Hemi.
Grand Wagoneer is great, but I don’t know anyone cross-shopping a 1/2 ton pickup and a Grand Wagoneer.
I build and race hemi motors, bought a 2025 with the Hurricane 6 and it has been very impressive so far
Really nice explanations for those of us that are not mechanics.
The 5.7 liter is a legendary engine literally see them daily in many Chrysler vehicles but especially Ram trucks a Ram truck isn’t a Ram truck without a fuckin 5.7 liter hemi V8 under the hood.
Yeah it’s got garbage exhaust manifolds, and can get lifter ticks, misfiring (it has 16 fricken spark plugs make sure the ignition system is functioning properly!)
They are good engines because of the power and torque and they can LAST. It’s one of my favorite engines definitely. Some people shit on the engine because of lifter issues, or the manifold issues but you keep it maintained and don’t be a asshole to it it’ll last you and maybe it wouldn’t get lifter ticks if your lucky I’ve seen over 150k miles 5.7 hemis that sound fantastic no internal noises.
I also enjoy working on them they are pretty straight forward
It’s the only engine I’d buy in a modern Ram I got 2 with the 5.7 a 5.7 hemi magnum original, and a 2017 with a 5.7 hemi.
If I’d buy older than 2003 it be a 5.9 360 obviously
This straight 6 will be legendary after the first generation. Watch the hp and torque climb in a year or 2. I see 500+hp easy and smooth as silk.
I keep hearing about the power versus the hemi but as someone who tows a 32’ camper that maxes out the payload and towing capacity of my 1500 I can tell you that power is not an issue. The issue that WILL be a problem with these turbo engines is engine breaking. I don’t see it being as good as a v8 engine and when you’re towing stopping and overheating breaks is a bigger deal than a slight bump in power that I didn’t need.
thanks for the video! I went from 6.2 HEMI in Grand Wagoneer to the 3.0 HO in GW and have about 9k miles on it. so far it feels faster to accelerate and so far reliable but like you said basically no more efficient on 93.
Its always in boost so no lag that I've noticed, stop start still annoying and gets off the line a little jerky when the engine goes from off to pulling away from a green light.
miss that v8 sound though, the 3.0 HO is a deeper note than the 3.0 SO that is in Wagoneer - this engine almost sounds like a tuned import sound
Adding port injection and a dipstick would alleviate a lot of concerns.
Planning on driving my 2020 Grand Cherokee into the ground. Hopefully by the time i need to replace it, this new Hurricane inline 6 will be sorted out. Still not a fan of direct injection only. Combination DI/ port would have been a smarter choice.
Love the change of scenery! Another great video
Some minor bolt on mods that engine could sound amazing! They put baffles on intakes to quiet them down. Exhausts have massive mufflers and resonators. Take those out and I bet this engine will sounds sexy!
You want to use a water to air intercooler for shortening the distance between the turbos and the intake manifold, if your goal is avoiding turbo lag on a daily driven vehicle, that's the way to go. For a race car doesn't make sense because you always will have the rpms high and for weight savings, but for the street application is the way to go, especially with a separate coolant system, now the ability to transfer heat to the atmosphere depends on the system quality
Good review!!
Should be a beast in a Wrangler...
You hit a lot of points that are certainly pluses for this new engine. One thing I wish they would have considered was a single turbocharger. It just would have simplified things above and beyond what you highlighted. Maybe the power production couldn't match up to twins.
My 2020 F150 3.5L ecoboost had an aluminum oil pan from factory. So, I don’t think it’s an issue anymore
I have a 2020 f150 with the 2.7 and it has the plastic oil pan. Not sure why ford decided to do that but mine hasn’t leaked so I dunno 🤷🏼♂️. Hopefully it’s good
Great video. I have test driven these in the standard output wagoneer and they are very fast. Much faster than the old 6.4 Hemi in the Grand Wagoneer. I hope Stellantis didn't mess it up and this is a good reliable engine.
I think this engine is very promising, I’ve been waiting for manufacturers to go back to inline 6’s and I think this one has the potential to rival the old 4.0 in terms of longevity and legacy. Even though it’s much more complicated, compared to most other motors this one seems really serviceable and the ability to run on 87 octane opens it up to more remote or fleet operations. Here’s to hoping it holds up well 🤞
My son who recently traded his 2016 Mustang GT for a 2023 BMW X5 plug in hybrid which he really likes flew from CA to help his Mom and sisters family after Helene who live close to Asheville rented a 2025 Ram Rebel with the Hurricane engine. He loves it so much that he's now planning to trade his BMW for a new Ram Rebel.
Great review, but what’s missing is what are the mechanical, fuel injection details and ECU alterations between the SO and HO engine variants?
Great content Getty Adventures, I'd love a video talking about the SO vs HO hurricane engine. 👍
I’ll stick with my 2020 Ram 1500 Classic Hemi as long as possible. Does everything I need it to without being overly complicated to work on or costly to maintain, and was $32k brand new. Couldn’t even afford to look at a new Ram even if I was interested in the Hurricane I6.
I bet a new Hurricane engine would around 30k alone lol
@@GettysGarage Price for a new crate hurricane is around 8k U.S. They just released the pricing on them.
I know no one will believe me but I got my 2019 ram 1500 quad cab v6 for $20,500 out the door right before car prices skyrocketed. I owe $643 on it, will be paid off tomorrow!
Same truck from the same dealer right now, $42k!
It might be a real interesting point to see if Stelantis is still going to be a thing here in the US much longer. They are embroiled with much litigation and investigations her in the US for their business practices.
Their European owners definitely don't seem too interested in the US brands since they are trying to force them to design their vehicles as if they are selling to a European customer.
I probably would have put the intercooler below and in front of the bottom of the radiator. And for you people that say that's stupid, it's done on ALL semi trucks. They are about the same size as the radiator.
It's an air to water intercooler. I'm not sure all that extra plumbing would be useful
That's the way my 6.2 Chevy Silverado Edelbrock supercharger kit has it placed.
That area is the first to be hit if you misjudge your ground clearance; not sure Ram wants to fight all the warrantee claims that would result.
It has an air to water cooler so you don't need to put it somewhere to get air flow.
Another point i should say is Ram trucks use 0W-20 oil, which gets thin faster under heat. I urge owners to change to 5W-30 fully synthetic ASAP.
I think, it’s nice to have opinions from experts like you.
Was on the fence over a new 2024 1500 with a 5.7 Hemi or a 2025 with the 3.0L TT. After comparing the two, I ended up purchasing a 2025 1500 Bighorn. It was the obvious choice for a more capable pickup. I'm going to miss the unique sound the 5.7 makes. That and the 6.4 are some of the best sounding engines I've ever heard and had the pleasure of owning. Engineers really did think things through while designing the Hurricane, I trust they made the right decision to move foward as the standard. Stellantis/FCA has been setting the bar for high perfomance engines in North America for over a decade. I doubt they'd slack on the 3.0L straight six and it shows. Or maybe I'm just biased from the 4.0L days. The new truck is a dream to tow with. You don't have to rev out the engine to stay in peak power and is smooth as butter during acceleration. Torque is immediate with out lag. It still feels like I'm dring a V8, minus the sound.
There is anecdotal evidence suggesting higher oil consumption with plasma coated engines from Ford, but I am shocked they did not use forged pistons with this engine running 0ver 20 pounds of boost.
the HO uses forged pistons. but yes the SO uses cast.
Nicely done! Very informative.
Cann you do a technical comparison between the Hurricane and B58? Everyone always mentions the B58 when talking about the Hurricane, but I've never seen a real comparison.
The H.O is more similar to the S58 while the S.O is closer to the B58.The B58 would strike better because it comes with forged internals and crank from factory unlike the S.O hurricane,while at the same time,the S.O has the advantage of having twins and having more power out of the box unlike the B58(other than the new TU3 B58 that comes as dual PI and DI from factory)top of them both having close compression ratios and etc. The H.O is similar/a bit better than the S58 only because it comes with forged internals unlike the S58 that comes with the same internals as the S63(may have gotten this V8s name wrong)V8 that are known for bending over 700whp(of course people have tested it and have gone over 800+whp with them but that's still risky regardless)along with the H.O also being plasma sprayed similarly to the VR38 and coyote. Main thing is that both are twin turbo but the hurricane has more power out of the box(well, highest hp model atm has 550hp)but the S58 has a lower compression ratio than the H.O while still being not too far off the S58s compression ratio even then.
But, does it sound as good as my 5.7l on cold start? No. 😊 a few things... 1) with the shake up at the top, it sounds like a v8 may be coming back. 2) I don't understand the push from the EPA to go to these turbo 6's that require 91 octane and get the same or worse real world mpg as my 5.7l hemi. All that does is cost me more money at the pump! 3) 100% agree with the inline 6. 4.0l, anyone? Bulletproof. Hopefully they took some notes! Great video as always, thanks for all the great detail.
So no dipstick, if the sensor tells you low oil, how do you know how much to add?
if it is gdi only the intake valves will get crudded up...that servicing offsets some of the fuel saving when it comes to lifetime cost calculation...
I have a GDI engine with 90k miles. I installed a catch can at like 15k, but so far there has been no issues that I can attribute to carbon build up on the valves. I really think even without the CC, that most people will not have any significant issues if they perform regular oil changes over a similar period.
Just took a gamble on a Ram 1500 with the high output..
Have not taken delivery yet..
It sounds really busy, a little more than I like. The rattle would make me go crazy. I have a Bighorn 1500 eTorque that is very quiet running and has zero vibration.
It’s the loud direct injectors… My Honda sounds the same with direct injections.
While driving, this is by far the most quiet running and smooth engine compared to the big 3 and toyota because it's a inline 6 configuration.
Ive had 3 reports from people that own them. 1 is happy 2 isn't. The 2 that isn't had issues out the gate. One blew oil all over underneath the truck. Other told me the engine failed on them at 15k. Shop that towed it in said alot of cheap part and shortcuts were taken, especially the 2 turbo. This is why I wait 3 or so years to get a new style engine.
High pressure direct injectors are noisy as hell. I hate that they kinda ruin the better noises that engines make.
They put the exhaust on the wrong side for a home run. They should have the exhaust on the opposite side so there isn't a crossover of both the exhaust and the fuel. Or have the fuel on the right side for easier fueling at Costco, but the DT rams already have them on the left so...
Cant wait for this engine in a Wrangler…
Seriously it will bring back the 4.0 nostalgia
It would be very interesting and entertaining to watch the engine data log’s along side the towing loop videos that you do with these trucks.
It's using an open deck, that's gonna add up to big problems before 30k miles. Also the HO model is the engine that comes with a forged crank and connecting rods. The standard has a regular crank and connecting rods
standard has forged crank and rods. HO has forged pistons rather then cast.
The Hurricane is a closed deck block. It's little brother, the 2.0L I4, came out in the 2017 Giulia, 2019 JL Wrangler and all the 4xe's.
I would absolutely love to hear your thoughts on the 3.0L duramax as well. I'm currently looking for a truck to town a jeep on a trailer, and ive been devouring your towing test videos. Great stuff. Your 5.3l and 6.2l tow tests were great! and the 2.7l turbomax really helped me decide to steer away from that engine for my needs. The 3.0 SST from RAM is on my list of possibilities, as is the 3.0 duramax in a silverado or sierra. Got any diesel mechanic opinions about the 3.0 duramax? Thanks for all the content!
I was told the water after cooler results in shorter distance from turbo to intake resulting in quicker boost
Correct, much quicker response time and air to water is more efficient (despite what he said).
My 22 F150 3.5 doesn’t have a plastic oil pan🤷🏻♂️. My previous 18 F150 with the 5.0 did though.
The architectural basis of this engine is the Alpha Romeo 2.2 liter 4 cylinder that started life with 122 HP
Thank God the manufacturers around the world are going back to inline 6 (BMW never changed-that tells you something), could never get my head around why you would deliberately introduce complexity, plus and more importantly balance, as well as space, modular design (inline 3,4,5,6 cylinder) etc etc.
I still love my diesels though. Effortless torque, however I REALLY like THIS engine, which is most unusual for me (very old fart-stick in the mud)!
I just bought a 2025 ram with the hurricane SO, I couldn’t be happier with this new engine, I’m coming from a 2021 Hemi. I’m so sick and tired of the naysayers, both of my trucks were bought with the 3.92 gears, I’m getting 3mpg better truck alone or towing. And this thing will spank a Hemi, from a standing start or rolling.
On the surface it looks good, sounds weird though. Time will tell!! I drove the hurricane for 2 weeks and the thing that bothered me was only 21 psi oil pressure at 70 mph, my 5.7 runs 52 psi at 70 mph
2 stage oil pump on newer engines, less pumping loss. Above 3k rpm it switches to higher stage.
The i6 does have less parts, but those parts are doing twice as much. Does that mean less to fail, or that what remains is now twice as likely to fail?
Million mile Inline truck engines easily squash your logic.
I bought a new Ram 1500 Big Horn with the hurricane. It'll get up and run but I absolutely hate it for just cruising around and keeping a steady speed. It doesn't get any better gas mileage than my Hemi did. I regret getting rid of my Hemi. I've been a big mopar guy all of my life but if they don't have another v8 out come time I get another truck in 2-3 years I'll be going to a different brand.
I have been driving Hemi's for many years and I never drove one that got above 17 mpgs.
You’re doing it wrong
I sometimes get 18 with a tail wing going downhill...in eco lol
@@joseeduardo4327 Driving the speed limit is now somehow wrong?
I've been getting 19-21 combined MPG consistently with my 5.7L etorque RAM 1500. I've noticed Shell gives me better mileage than most other stations near me. Make sure to use mid grade if you aren't already. Regular brings the mpg way down.
@@BeRyan8923I always told family members & friends that shell’s formula gives better gas mileage especially on the highways. I recently got 24mpg on shell mid grade gas, 2hrs drive with cruise control set @70mph and gears manually selected to +8 to force all V8 cylinders working (hate eco mode).
IF Stellantis had applied the same technologies to the 5.7 it would out perform the I6... twin turbos, Forged Components, Fixing the tick, better oil pump for better flow.... etc... It would be closer in balance than the V6... I could go on and on. It have a better sound as well. They also could have increase batteries and added roof solar chargers and increased fuel tank to be largest of all 1/2 tons and increased towing cap... on and on... would be great to see some after market designers and engineers go after besting the Hurricanes in power and fuel economy for less than Stellantis spent on the Hurricane.
Enjoyed your video, I too had watched the second video you had referred to. I bought a 2025 Ram 1500 with new motor and so far so good. Several comments on a owners forum commenting on a misfire which triggers a "check Engine" light. Had heard an "on line update" is in the works-any info on that ???
I do worry about direct injection, plus where's my dipstick
. Plus truck prices, I think I'll keep my 2015 Hemi for a while. Looking forwards to the next videos.
Very good points, they are also major to me. Besides these major points, I am looking forward to the I6 in general, because as he mentioned, the engine design (independent from Dodge) has many advantages, but yes: It's lacking the "balls" from a V8, but therefor it's just smooth.
Love your engine videos
The fact that the cylinder liner are treated with a specialized process only an OEM has access to, tells me that the engine blocks are throw away because no machine shop will be able to re-bore and hone these. Good job Stelantis.
You can install press-in cast iron liners in engines with proprietary cylinder liner coatings. Kind of expensive but doable
NO need to rebore what's your point....pray tell.
Price on your fuel economy comparison the hemi was on more expensive mid grade fuel and the I6 was on regular grade. That will add up.
At 2:27 he said my name, so sub earned.
Well, a gasoline engine with SCR and GPF (gasoline particles filter) will be as complex as a diesel. In that case, I prefer diesel. No knocking problem, no VVT or variable lift, no spark plugs, etc... and during partial and full load, they are more efficient. We have a lot of diesel in my country (Isuzu Dmax, Nissan Frontier, Toyota Hilux, Land Cruiser, Fortuner, Mitsubishi L200, Hyundais, etc...) and they get amazing fuel consumption for their weight. I had a 2007 Hyundai Accent CRDI, and that thing had a fuel consumption, in long trips, of 4.3l/100km in hilly terrain and a 3.7 l/100km as best, with the enjoyable torque that it had (173 lb-ft from a 1.5 liter engine), in city its fuel consumption was 5.8-6 l/100km. A friend has a Toyota Fortuner (3.0 turbo diesel, 1KD-FTV), it gives him 12 l/100km, his son-in-law has a 2011 CRV, the CRV gives 16 l/100km (Nothing wrong with it). So, a heavier 4x4 car vs a crossover, and with better fuel consumption, recipe: diesel . Greetings
I myself can't wait for folks to start tuning these. I'm curious how much boost the spray in liners will hold. I6 engines have always held a spot in my heart.
I still do not understand how all these vehicle giants did not know about the strength and balance of an inline 6. Someone got bought out obviously , because I was 13 when I seen the 2J build and understood the wonder. I am 37 now making 500hp off a rotary that would fit on your 3yr old's table. 6 years later, same engine, same everything. We need to embrace Japan's quality.
It’s all about packaging since it requires a longer taller hood line than a v configuration.
Sellantis has a reputation for putting out junk. Hopefully this is an exception. As you said. It is what it is.
But I can’t even check my own oil level. Should I really trust sensors to tell me oil level? Little scary to me. I’m an oil nerd… so this is gonna take a while to get used to an engine with no oil dipstick where I can physically see my oil
A non-issue in my mind. Maybe paying a little extra attention when you do your own oil changes to see if everything matches to what the vehicle says, but after that I bet you’ll forget to worry.
@@ALMX5DP ... until the warning light fails and you don't know you're low on oil until it's too late and wipe out an expensive engine that Ram won't warranty > > > all because some idiot engineer/ bean counter saved a few pennies by removing a dipstick.
@@hmdwn you sound so certain of a failure at the most inopportune time, I presume you also believe if/when that occurs (sensor “failing”) there will be no indication made to the driver? Any foundation for this colorful opinion of yours?
the no Dip stick is a mistake in my opinion.
I have owned BMWs with oil sensors. There are several advantages with the upgrade!
1. 99% of drivers do not check their oil ever.
2. If the sensor fails, you will have an error message.
3. Driver will be alerted if oil is low!
4. Sensor works while driving and saves many engines from blowing up due to a rock to the oil pan or an oil cooler system leak.
5. Saves the OEM big time on warranty claims. They can tell if you ran without enough oil. Costs us less not paying for others mistakes.
6. Easier to catch fuel dilution caused by improper fuel injection.
What’s not to like? You can still smell the oil fill tube if you possess mad skills and you can determine if there are issues with the oil.
I am curios to know, why the I6 (with Turbos) is less efficient in the city compared to the V8. Surprises me. Is there a logical explanation, or is this probably caused by enforced emission requirements which are choking down the efficiency?
isnt the hurricane engine just the jeep 2.0L with two more cylinders?
Basically,just with a closed deck block,forged internals and crank(H.O version has this but not the S.O),and another turbo.
Yes they are related, same deck height and bore spacing. The 2.0L has been pretty good so far.
What’s the difference physically between the High output ecoboost and the standard 3.5 ecoboost
H.O
-More hp(510-550hp from factory but is model dependent with hp)
-H.O can only take premium(S.O can take reg gas)
-Is a I6
-comes DI only unlike the ecoboost coming DI and PI recently
-has a closed deck block unlike the ecoboosts open deck block.
-comes with forged internals and crank(S.O doesn't have this unfortunately).
@@carboydorifutoparty3976 what was the statement, bullet point under the one about fuel, I didn’t understand it
Please redo the deep dive on the tundras TT v6. I would love to see a more in depth review on that one.
But does it have an oil dipstick?
Air to water is a large improvement over air to air. Air to air is used more often because it is a simpler system with les moving parts. But air to water is more efficient at cooling the air charge down. Just look at all drag racers makong big power most of them use air to water
What's the compression ratio for the Hurricane? You mentioned Knock, but a NA engine would ideally run at higher a higher compression ratio meaning knock is more important to manage
Let’s hope they do succeed with this new engine . They have failed in the 3.0 Turbo diesel engine with a total nightmare! The 2.4 turbo 4 cylinder also problematic engine. Now water cooling the turbos!! Well will see how long these turbos will last
