Chrysler has another 3 liter Diesel, but its a 4 banger

Wonder if this might end up being the JK option, though I actually hope not. Its the same displacement as the V6 in the Grand Cherokee, but its a turbo inline 4 instead of a V6.

Its going to be a $4K option in the new Ram Promaster full sized vans. I'm actually hoping this doesn't wind up being the choice , but since its being offered at about a grand less than the V6's, they might think it makes sense for the less costly JK.

This is *not* the 4 cylinder Diesel in the European JK's.

It is my understanding that inline engines will usually have more torque than their V configured cousins. All else being equal.

If that is true, I would prefer an I-4 over a V4 or even V6 with same displacement.

I have no interest in a high revving diesel v6 but a little torque I4 would be something I would be excited about :)

A high revving V6 Diesel for truck or SUV use is a bit of an oxymoron. With the small size of the JK engine compartment and the GVWR, an inline 4 cylinder Diesel is the perfect engine choice for torque.

Perfect statement.. Except should have said 4 cylinder TURBO diesel. ;)

I don't see a problem with a 4 pot diesel, they're naturally torquey which takes care of the off road performance and the the turbo can be tuned to provide sufficient horsepower to improve on road performance.

Selfish, I guess. I want more than just enough power. Still want it to feel lively with 35's and 500 pounds of bolt ons! :)

I am with you. There is no replacement for displacement.

Um but the OP says the 4 cyl has the same displacement as the 6?

This is true. I get what Rubi is saying though.
The 4 cylinder makes 174 horsepower and 294 lb ft of torque.
The 6 makes 240 horse and 420 lb ft.

Someone mentioned the Grand Cherokee Diesel needing to be revved, and I'm not sure where that notion comes from as it makes peak torque at 2000 RPM.

i82much 09-05-2013 01:32 PM

Good grief, those numbers for the 4 cyl are awful. That thing will be slower than a 3.8.

Oops didn't catch that.

Just give me the 5.7L diesel from the 3500!!! and 850ft/lb of torque

Ha. There IS a replacement for displacement - compression/efficiency. When you start squeezing more than 800 hp from a naturally aspirated 5.9L V-8 with a carburetor, we can debate that. On that note, I'd be super psyched to see a "high tech" retro engine make it to the JK just from a novelty standpoint.

Otherwise, an I-4 or I-6 is THE right answer to the JK engine question...the rest is just details (gas, diesel, turbo, whatever).

Hokieneer 09-06-2013 09:35 PM

If I recall correctly that engine only meets emissions because it is in the promaster and falls under commercial vehicle standards, It's possible they could modify it for the wrangler but I hope they are smart and stick with one engine the V6 with 420 ft lbs:jawdrop:

I am getting right at 600 h.p. & a little over 1000 ft. lbs of torque with my 5.9 liter cummins. I would love to see them do that with an I4.:)

I think you meant 5.9 or 6.7

I have a buddie with a 6.7 he was on the dyno at 779hp and 1695 ft/lb. He also uses it as one of his DD :). One time in our industrial park where we tune an owner of another company came by with a 08 Z06 and they lined up.....Coolest thing I've seen in a while. He smoked it literately :) Just odd to see a big ass truck move to fast lol

The difference is where the torque is. If it is at redline its useless. If its at 2000 rpm you use that all day long. My old VW 1.9 tdi would blow the doors off most with double the displacement.

It's amazing the power you can get out of a diesel.

Diesel engines in the wrangler? Eek, hello 1985.

Tomdata 09-07-2013 06:42 PM

Diesel fuel has more potential energy per gallon than gasoline.. With proper engine design and fuel/spark control its not a fair fight. Add a turbo and its game over. There's a reason semi trucks, boats, military transports and commercial generators all run on diesel fuel.
2015 dodge ram 1500 - v6 turbo diesel
2015 Nissan Titan - i4 turbo diesel
All over the world diesels are used in various cars, Tacoma, sequoia, Acura tsx/tl, jeeps, subarus, bmw's, Mercedes just to name a few

Solid axles? Body on frame? Zip out windows? Hello 1941.
The Pentastar still feels at least 50 hp short of a full barn.

DJL2 09-07-2013 07:07 PM

Diesel Engines? Man, that's so "Won the 24 Heures du Mans just like the last turbo diesel Audi made."

Heh...improper cylinder configuration aside, the R18 speaks well for the merits of diesel in high performance applications.

I read the Nissan Titan will use the 5.0 v8 cummins. That should be sweet
