I would assume most manufacturers area always working on new engines. I would also expect it to be a multiyear process. I also wouldn't expect a new engine for the JL until a midlife update.

There is also the rumor that there will be a new mid size truck running on the Jeep line. I'll assume it's a RAM version of the Scrambler.

If it comes to the Jeep line, I hope it's much better than the 4L was. I did not realize how bad that one was until I drove my first 3.6L. I'll take this bent 6 anyday over the 4L.

100 more horsepower does that to an opinion. Consider the 4.0 was developed in the 80s on an architecture that went back to the 60s/70s... It worked pretty well, but yes a newer engine that came out almost a decade after the 4.0 was discontinued should be better than the 4.0.

I had the opposite reaction. I drove a 4L again a couple of years ago after driving a 3.6 and it made me miss the low end torque.

I owned 2, 03 TJs with autos that I absolutely hated - one with 3.73s and one with 4.10s. The transmission was just wrong for that engine. I've owned 3 Manual TJs and they were not nearly as bad as the auto......so maybe my issue might be with the transmission rather than the engine.

However, given the choice of either engine in the same vehicle, I would always take the 3.6 over the 4L. It just seems to fit my driving better. And personal driving impressions are usually what sways us. The 4L was a great motor in it's day, but I really like the 3.6.

disclaimer - I did not read the articles.

How would an inline 6 cylinder be different than a V6? what's the benefit? it's still 6 cylinders amirite? :giggle:

Inline 6s have all 6 cylinders in a row, while V6s are in a V shape with 3 cylinders in each bank.

Inline engines are USUALLY built with a longer stroke and a smaller bore. They are usually lower rpm torque motors by design. They produce increased amounts of torque at low rpm for increased power down low.

V engines are USUALLY shorter stroke and larger bore and produce power at higher RPM. They are usually higher rpm motors that rely on rpm for power rather than torque.

There are of course exceptions to this but the above decent generalizations about the 2 different designs.

I should have made another disclamer: I know nothing about engines. Not too long ago I learned how to change the oil myself though! :rock:

Thanks for the explanation.

I do agree with the automatic transmission. Just terrible. But I did like the ax15 with 3.73 gears.

Absolutely perfect description...that's how my dad explained it long ago lol. :)
I had the same question about why his inline 6 cummins diesel engine (5.9L) wasn't a V6...since he used it to tow...your description about "increased amounts of torque at low rpm" makes all the sense in the world.

Heres a video explaining pros and cons.
