Report: Pentastar V6 may be replaced by inline turbo 6 cylinder engine

[Suffolklou]

That would be pretty dang cool! The last great Jeep engine in many people eyes was the 4.0 HO I6 in the TJs, LJs and Cherokees.

Dont forget the YJ

When the Pentastar was designed it was designed with a turbo in mind. I don't know why they didn't ever offer it. Reduce the CR use some solid rotating assemblies and throw a good turbo on it with DI and it should be a beast.

This article from November claims:

"The development of an entirely new six-cylinder application was said to have been kicked off after direct-injection tests on the Pentastar V6 proved disappointing. Chrysler engineers decided an entirely new six-cylinder engine would need to be developed."

Very interesting. I missed that when I read the article before. I guess that they have axed all of the original plans that they had for the Pentastar other than the Maserati version that they only produce in limited quantities. Seems a shame as I could see the potential that the engineers developed into it. We were supposed to get a turbo version around 3.4L and there were even rumors of a V8 and later a twin turbo version of that 3.4L and a turbo version of the V8. Woulda, coulda, shoulda...

Why does everyone hate on the YJ?

This is why.

It was designed when AMC was going under and it was truly a parts bin special. Some things were an improvement over the CJ, but it is generally considered by most to be not as good as the CJ. I still remember rebuilding that POS Peugeot transmission on the barracks room floor after my roommate lost reverse and second in his Jeep.

My '93 YJ was my first Jeep, I loved that jeep. I will never forget the YJ, although the Renegade was bad...

The turbo I6 prototype is a stretched GME 2.0L which makes sense as they've invested a lot into that engine, and modern plants to produce it.

This is why.

That trim was hideous, but the YJ also gave us this:

Any new updates on this? I’d be very happy with an I-6 with forced air or a factory offered Pentastar with forced air.
