Jeep: give us a new power plant!

[dcmdon]

It didn’t

I figured that out 2 posts later.

In fact the I6 in that Jeep made 98 hp!!

Re CAFE - its no coincidence that the volume engine upgrade for the Wrangler is the 4xE hybrid with 375 hp.

I'd be curious to know how much longer than the current engines this motor is. If its too long, it may have to wait until the next model Wrangler is released.

There's obviously little solid info out there. But it is said that it won't simply be the 2.0 with 2 more cylinders.

There are supposed to be a number of changes to make it more compact, including tighter cylinder spacing and forgoing steel cylinder liners (perhaps using the plasma lining process instead).

The net effect of all the changes is that the engine is supposed to be no more than 3" longer than the 2.4l Tigershark 4 banger.

But again, a lot of this info is unconfirmed and from unnamed sources. And most articles are simply repeating what the source publication said.

I agree that there needs to be better engine options. I hated the 3.6 in my 2018 JKU, it was the main reason I traded it in for my diesel JT. There was no power or torque below 3k rpm and was horrible on fuel (stock tire and gearing), almost as bad as my 77 F250 on 37's.

Cummins inline 4, baby!

The lack of reasonably priced engine options is one of the main factors holding me back on buying a Gladiator.

I've decided that a 4xE will work for me. Forget that its a hybrid. Just think of it as a powerful engine with decent fuel economy. If you don't bother to charge it ever and just drive it like a normal hybrid, it will be a 20 mpg Jeep with 375 hp and 470 ft-lbs of torque. And a 10 year 100k mile warranty on the electric powertrain including the motors and battery.

Let that sink in. 375 hp. 470 ft-lbs of torque, as much torque as the 392 AND 20 mpg.

And as long as the Federal incentive of $7500 is in place, no appreciable cost increase.
I priced out a Wrangler with the Pentastar and with 4xe AND my state's incentives and the 4xe actually costs less.

A lot of us wish we could have the 5.7L, and they'd sell like hotcakes. @tjZ06 mentioned it would probably make it hard to sell both leftover Pentastars as well as new ones, but even with that going on the problem is not with Jeep, the problem is CAFE and MPG standards from DC Sky Daddy

Exactly.

We are going to see more and more high powered hybrid systems taking the place of the next step up engine as time goes on.

Like I said above. I could not care less that the 4xe drivetrain is a hybrid. I just care that it makes 375 hp and 475 ft-lbs of torque with decent mileage.

It pretty much does what a 5.7 will do, though with much more complexity and weight. But its essentially free at this point in time.

I agree with some of your post. The 2020 - 1978 spread is excellent. Thank you for that!

But respectfully, I think Ford's small displacement turbos fall into the 'throw away' vehicle class.
These aluminum block and aluminum head engines with incredible boost through a turbo have a shorter lifespan. Check the EcoBoost websites.

If you lease a EcoBoom; Who cares how long it lasts. Auto manufacturers love you.

If you buy and plan to keep it 15 or 20 years, a small displacement aluminum based turbo is not what you want.

As it was said in a older movie: "A light that burns twice as bright, burns half as long".

Go N/A.

Not only are there the longevity issues, but in my experience these modern turbo engines don't get close to the window sticker MPG. Additionally, MPG takes a nosedive when towing and hauling. Those turbos aren't gonna be spinning unless a lot of air and therefore fuel is moving through the engine. Then, the more air the turbo packs in, the more fuel has to be brought in to complement.

 

[dcmdon]

I agree that they don't last as long. But its pretty well established what you need to do to make an eco boost last. Specifically 5k mile oil changes.

All engines whether turbo or not use extra fuel and air to make more power. That's just how it is.

I think the thing about the 2.7L turbo is its really in the "just right" range. Most don't want to pay big bucks for a 470 hp 392. And even if it was only a $5000 option, many wouldn't want the 13 mpg fuel economy.

A medium displacement turbo V6 makes plenty of HP and loads of torque. They are very common because they work so well in so many vehicles.

To quote Roman from TFL: "You can have 'Eco' or 'Boost' but not both." LOL

That being said, a straight-6 TT + Hybrid would make me salivate.

To bad almost no one makes 5cylinder engines anymore

Wierd is these v6 have v8 power from 12-15 years ago. However- I don’t get why there isn’t some updates which result in some enhanced power over all these years. Going on 9 years…
even the 1999 4.8-5.3 gmv8 received as much as 20 more horses and now makes almost 70 more hp in the 5.3.
I just don’t get why they haven’t invested more in this platform since it’s the sliced bread- everything level equipment they use in most FCA vehicles…. I mean really……

Yeah I try to tell myself that my old 5.9 really isn't all that powerful compared to the 3.6, but then again it does have 330 lb-ft of torque. All the diesel-complaining in these hot temps lately has me reconsidering the pentastar this week for sure.

I can really see where even a 15 jp increase and some torque would be possible

I believe this is where displacement comes in. It still takes X amount of power to do Y amount of work. The V6 is adequate but not much reserve when fully loaded.
