Default FCA New Turbo Inline Six Beat 5.7 Hemi Ratings

Quote:
brand new FCA inline six-cylinder engine turbocharged to meet or beat 5.7L Hemi power ratings while having a smoother torque curve is on the way, according to patent drawings discovered by AllPar.com.

The first vehicle to get it might be the Jeep Wagoneer or the next-gen Grand Cherokee, but it’s also bound for the Dodge Charger and Challenger and may replace the Pentastar as the base engine on the Ram pickups.

To keep space requirements low, FCA is going to have to pull out all the stops, so it’s not likely to be a GME four-cylinder with two more holes tacked on. The engine will have relatively small bores, closely spaced, to reduce its length; Lancia and Volkswagen have some old tricks that may come into play. Since every millimeter counts, Chrysler’s traditional steel cylinder liners may be rejected in favor of aluminum hardening. Reportedly, the goal is to stay within three inches of the current 2.4-liter four-cylinder.

ALSO SEE: 2020 Jeep Gladiator is the Wrangler Pickup You’ve Always Wanted

The expected displacement is just under 3.0 liters, coming under a displacement-tax threshold, with power boosted either by twin turbos or by a twin-scroll turbo. The code name might be Tornado, or perhaps that’s wishful thinking. In any case, the engine coded Hurricane is known as the “2.0-liter four-cylinder,” so it seems likely the GME-T6, even if nicknamed “Tornado,” will just be called the “3.0-liter six-cylinder” in official statements.



Forced induction would likely be through twin-scroll turbochargers for the Chrysler versions, and perhaps dual turbochargers for Alfa Romeo and Maserati, if they share it. Any Italian versions would most likely have Ferrari-designed heads and different blocks.

Straight sixes are inherently smoother than V6s, and have a bit of snob appeal, given their use by BMW (mainly) and by Mercedes.

The return of the straight 6 to Chrysler.... wow. Used to be the staple of engines back in the 60s and 70s. With modern fuel controls, DI, etc... these can be really fun. Will not be sad to see the V6 die off.

The old inline 6 were damn stout engines. I wouldn't be surprised if these end up making more power than the Ford ecoboost while being same level of reliability. I am interested to see how they perform fuel economy wise. Maybe I was under the wrong impression but I thought typically inline 6 gets worse than v6 mpg's.

Inline 6 used to get slightly less than V6, yes. However, that shouldn't be an issue with DI these days.

The big switch from I6 to V6 was for packaging (both vertical and length, along with FWD transfer cases) and crash testing. With better safety structures these days, and higher hoodlines are a thing (no more sloping to bumper), and a move to more RWD cars again... you have a little more room to play with. This could be good news... sad thing is, not many new drivers even remember how stout and reliable I6s were compared to the V6s.

We had a Volare in the fam with the straight 6... 200+k miles "just add oil". I also had an '84 Maxima, brother had an '82. The 84 was the last year of the RWD I6 Maxima (the last real 4DSC). For '85 they went V6 FWD.

Sounds like a peach of an engine. Those old slant 6 motors were stout indeed. My parents bought a '71 Valiant new and put about 115k miles on it. They sold it to my baby sitter who put another 150k on that engine before it finally threw a rod in 1985. She took that car through every single one of the lower 48 states as well as Mexico and Canada. Never needed anything but tune ups, tires and a few clutches. You did have to hold the shifter on the steering column in place when driving in second gear for about the last 7 years of that cars life, though.

Please let this make it's way to the Wrangler! ****, I'll even put my "manual or else" ego to the side. This in the Wrangler pickup would be the ****.

Inline 6 cylinder is also a balanced engine from a vibration perspective. Engine mounts can be simple and cheap.

Especially that one. The engine exhaust note completely ruins the car. Even more than the angry bird pig rear end.

Exactly, though I request that the crank not be flat.

The 5.7 gets as good mileage as most 6 cyl so go for the 5.7 for now till they work bugs out.
I had a REM 1500 5.7 and it had way more power and better mileage than the 6 cyl Chevy Colorado I drive now for work.

Production started November 22, 2021 at the Saltillo Mexico engine facility. It was publicized last week on Stellantis' media site. When word started getting out, Stellantis edited the page and took the info. out. It appears like we should start seeing it in the next model year. Not sure why the ninja edit on Stellanits' part....

Rumors are a base engine HP of 360 and a HO version topping out around 525HP with a version also somewhere in the middle.

Default Jeep and RAM ready for life without HEMI V8

Quote:

Jeep and RAM ready for life without HEMI V8

Long-running 5.7-litre HEMI V8 to finally bow out to more sophisticated inline six-cylinder
Stellantis is primed to finally pension off its third-generation HEMI family of V8s after 18 years in production following reports of an all-new turbocharged 'Tornado' inline six-cylinder surfaced on the car-making group's official website.
Initially posted on the Stellantis' powertrain blog Stellpower but now deleted, referenced the all-new '3.0-litre GME T6' inline-six cylinder and confirmed it would be assembled at Stellantis' Saltillo plant in Mexico.

No further details or specification were released but it's thought its arrival is imminent and it is expected to replace the 5.7-litre HEMI V8 as well as the much mightier 6.2-litre Hellcat and Demon versions, plus the latest 6.4-litre '392' derivative used in the latest V8-powered Jeep Wrangler.

Instead of dropping the V8 altogether, it's thought the new inline six-cylinder will be introduced gradually – except in Europe, and possibly Australia, where Euro fleet average CO2 emissions will force the adoption of the new family of sixes far faster in right-hand drive models.

Confirmed to come with a 3.0-litre engine displacement, to meet ever-stricter emissions it's almost certain Jeep models will need to embrace electrification.



Plug-in hybrid versions are also expected to be offered with the new inline-sixes.
The first car Down Under likely to benefit from the all-new powertrain is expected to be the new fifth-gen Jeep Grand Cherokee, with the inline-six set to also replace the ageing 3.6-litre V6 Pentastar petrol engine – It's already been confirmed Australians' will miss out on the V8 offered elsewhere.

Tracing its history back to the early 1950s, the HEMI V8 takes its name from a hemispherical cylinder head that was invented to provide an enhanced surface-to-volume area for a more efficient burn.

The most powerful supercharged 6.2-litre HEMI V8 produced up to an incredible 603kW and 972Nm of torque under the bonnet of the fearsome Dodge Challenger SRT Demon – channelling all that might to its rear wheels.

Pentstar V6 always straining to keep up. Just does not have power or torque to feel comfortable drive in Grand Cherokee and way too anemic for the Ram 1500.

You know I have the pentastar in my Grand Cherokee Trailhawk. I have always felt it was a very adequate and decent engine. Sure it is not a Hemi, but it moves the GC down the road quite well. Gets decent mileage, and is really smooth and relatively quiet. It is not a superstar engine, but I would not say it feels strained. I am at sea level though, so maybe my opinion is a bit location limited.

I've rented a Durango GT a couple times for 6-8 hour road trips with equipment for work. I agree, adequate is the perfect word. Goes when you want to, quiet when cruising, and overall, unobtrusive.

Also, the Pentastar is mostly reliable.
