I test drove all three. This is only my opinion but I favor the hemi for various reasons. I really liked the diesel though, it's very energetic. The gas V6 is fine. Not bad but I would chose the diesel because I really liked the torque.

All that noise just makes it feel faster

Mine ran 0-60 in 7.3s stock and 6.8s after the Bluespark. If you powerbrake and spool the turbo up, the initial launch is awesome! Perhaps the car rags don't know how to launch a turbo? In the real world, we are typically rolling when we need to giddyup...like when passing or merging.

As far as physics go, sure both powerplants experience the same loads but its how they react that is important. As has been outlined and documented numerous times , the gas engine suffers a higher loss in efficiency under any additional load. Even towing a jet ski or having 4 200 lb men and some luggage in the vehicle has a more drastic affect in city and hilly driving. Higher speed cruising kills gas efficiency as well. This is a fact. Anyone failing to recognize these strengths in the real world operation of a Sport Utility Vehicle needs to do more research!

I can not understand the anti-diesel attitude in passenger cars and light trucks/SUVs. Why it is so important to resist any improvement because its not the same technology a person already uses? A very higher percentage of diesel vehicle owners stay with the technology after switching. The rest are unfortunately influenced by die hard "experts" with little experience.

Re: USA Today - Test Drive: New diesel Cherokee not quite Grand

Reminds me of the arguments back in the late 70's and early 80's about VW Rabbit diesels. I would let diesel fanatics drive my 2dr 78 Rabbit with the Oettinger 16v conversion, 5 spd, 4 wheel discs etc and their diesels began to lose their appeal when they smoked Vettes, 911s and Trans Ams at traffic lights.

Also remember in the EU and UK tax policy favors diesel engines. Its not a fair and balanced playing field over there.

Buy what you need or like. I dont tow so no need for a diesel or the so called hemi. I have a Pentastar and am happy with its performance. Its still a free country.

Diesels fill a niche market so lets hope the coming CAFE standards and our Green friends dont have eliminate choice from the marketplace and mandate
diesels with tax policy or other BS. There are times when nothing beats a high strung small displacement engine that can rev to 9 grand+.

Reminds me of the guys arguing in the 2 stroke vs 4 stroke dirt bike war. Care to guess who won? Who would have ever thought a heavier, less powerful bike would eventually turn faster lap times, even in the same displacement? (250F's now are faster than 250 2 strokes on closed tracks….but not yet as desirable in enduro mostly due to maintenance costs) Its all about "driveability". Its not a direct comparison but is equitable. The point is that technology changes.

Its great that we have 3 equally impressive options for powering the WK2. The merits of each are worthy of consideration. The market will ultimately decide...The RAM 1500 EcoDiesel will be interesting to watch. Anyone hell bent on trashing anything they don't own or understand can keep their "2 strokes" if they like 'em! ☺ Peace!

Re: USA Today - Test Drive: New diesel Cherokee not quite Grand

3 good engine choices, enough to make just about anyone happy. Get the one you like best, then drive and enjoy.

I test drove the diesel. From a stop, acceleration felt just normal and unexceptional... for about a second. Then the turbo kicked in, and I thought I'd mounted a Corvette. It startled me so much, I found myself pulling back on the gas pedal foot because it was too much acceleration.

I tow trailers all the time (literally 85%+ of my miles), and I figure that the diesel could save me between $500-$900 per year vs. the hemi.

Unfortunately, they won't sell a lifetime max care on the diesel JGC. I want to keep this thing for 15 years, and I am pretty sure that I will save more with lifetime coverage than I could save with the diesel fuel economy. So I am now leaning toward the hemi.

Oh, if only I could have both.....

Just a note on the acceleration, it smoothes out once the engine warms up. When it's cold, you get that sudden pull but it is warm, smooth as butter.

I so badly wanted a diesel when I was looking back in the summer. Waited and waited but they didn't come. So I bought a 3.6 because I had done the math and decided I'd never recover the cost difference with the diesel anyway, despite commuting 65 miles a day.

So I kinda settled and got practical for a bit.

So ever since the diesels started showing up, I've been curious. Today after having my Pentastar serviced, my salesman said they had a diesel demo they'd like to get me in.

I drove it. Yes, I like it. A lot. But I was also surprised that the torque didn't overwhelm me. Like a previous poster, it felt about the same as my gasoline 6. In fact, I thought the six felt a little faster.

But then I merged on the Interstate and felt a little kick there. Again, not as much as I would have thought, so maybe I'm just not driving it right. I like it but I'm not sure I'll be willing to pay the difference, even if they offer me a good deal.

Also, I noticed the average MPG was only about 19. 19! I'm getting 18.1 with my gasoline model.

Thoughts?

Probably the average mpg of a bunch start/stop "let's see how it runs" test drives. The torque is there but its a turbo so the driving style and throttle feel are different. Gas engines with an automatic give you a more immediate lunge then lits of revs and shifting. The diesel pulls stronger after the turbo spools up. Also, Eco mode causes early shifts. Did you try non-eco or sport mode?

If your 65 mile commute is mostly steady speed, you would see 28 to 30 mpg. I drove 160 miles today on hilly 4 lane 65 mph and my trip avg was 31.7 mpg.

Route 66 is a splendid one to behold
Since I live in Denver and drive into the higher elevations, I like having the turbo in the diesel since it looses less power in the mountains. Because I tow a trailer at altitude, the turbo diesel seems the obvious choice. If I still lived in Indiana and had no trailer, I'd probably get the V-6. I think the Grand Cherokee is a great vehicle no matter which version or engine is chosen. It's great that we have a choice and aren't locked into only one choice.

My wife is driving the V6 gas as I write this. After 80 miles at 65mph with hills we are getting 28.2 mpg. With fuel that easily cost 20% less.

That's very close to what epa DIFFERENCE is.

Oh plus $4500 extra in the bank.

If you go by $/mile V6 gas wins, easily.

Re: USA Today - Test Drive: New diesel Cherokee not quite Grand

It looks like you're getting extraordinarily higher gas mileage than most with your V6, while Execursion's are pretty average for the diesel.

Spend some time sorting through the data on fuelly if you want more typical trending of what most people are getting with their respective engines.
