My reasoning is simple on this. I bought a expensive SUV with all the bells and whistles. I wanted it to have ample power which is part of the comfort formula. The Overland is heavier. 45K and up on a Overland and you're worried about MPG? You bought the wrong truck I think!

Anyway....V6 or V8, the Overland has few peers.

Enjoy!

I got 21.5 mpg with my Hemi running 70 mph on the Highway. Why would I ever want a V6? Again if you want adequate...which seems to be the norm, get the V6. I don't want adequate. I have always opted for the engine upgrade on any vehicle I have bought.

Well said. Had I wanted "adequate" I would have bought a Laredo and the V6 or maybe a Highlander or another Outlander.

Nope! We were cross-shopping the LR4 and the Audi Q7 and I found the Overland with V8 superior to both. If my buddies V6 Overland was getting 27 MPG I could see the point. But when we drove side-by-side back from PA recently I got 22 MPG and he got 25. That's just not worth it to ME. For some it is.

Then you better run scared away from the starting line. My Aunt Ruthie's 2009 Toyota Rav 4 smokes my brothers Jeep WK2 Hemi all the time!! He hates it! And to be honest, with the Hemi, the 0-60 and quarter mile times are the same as the V6 numbers for the Toyota Highlander, and their minivan, the Sienna. So, if you think those are fast, then I can understand your love for the Hemi.

Re: Who has driven both V6 & V8 WK2's

I hit 26.5mpg (hand calculated) many times this summer during a 200+ mile trip at an avg 70-72mph. In the city I am always around 17-18mpg...with the hemi, I was lucky to get more then 14mpg in town.

If the v6 is only adequate, the hemi is just above adequate (and is below adequate for a V8). If the difference between the two was like going to the SRT then I'd agree with the HEMI posts, but it's not.

I know why, because you could have got 25mpg if you had the V6 ;-) Im only giving you a hard time.
Lets face it, most people DONT always drive strictly highway so when everyone says hey OMG I got 22mpg in my Hemi, well ok whatever that was just on the highway. Again, the bigger difference is around town and thats what swayed me to the V6.
For me the grass is always greener on the other side. Sure now that I have the V6 sometimes im wishing I had the V8 for the nicer rumble and get up and go, but then I know if I had the V8 I would be like damn I wish I could be getting those extra MPG using regular grade fuel. I have said this before and I will say again, neither Grand Cherokee is fast by any means! Even the SRT8 isnt really that fast when you look at whats available these days. Isnt it basically still a 13 second truck? maybe high 12's? I know even if I had an SRT8 I would get used to the power very quickly. The only car I have ever owned that blew my mind every single time I hit the throttle was my C6 Z06 vette. Downright scary! 505hp at 3,000lb's Now if I could only afford a ZR1

Re: Who has driven both V6 & V8 WK2's

The biggest reason you couldn't pay me to buy a v6 right now is the head issue. Personally I think the pentastars are all ticking time bombs. The lucky ones are the ones that are having the issue early (under warranty). The unlucky ones are the ones who are going to have the issue at 40,000+ miles.

Even those having it fixed under warranty should still worry. Chrysler has never said the found the root cause. So they are throwing a new head on and there's probably a pretty good chance you'll have the same issue again.

Another concern is the fact that people are having to wait 3-4 weeks to get the heads. Besides being a huge inconvenience it shows just how common this problem is. It's obviously much more common than Chrysler is letting on if they are replacing so many heads that production can't keep up.

Sounds to me like your brother should get some driving lessons from your Aunt Ruthie!

Re: Who has driven both V6 & V8 WK2's

Based on my limited research, the Grand Cherokee is not really a top performer with the V6 or V8.

FWIW

In Edmunds testing, a 4WD Overland V6 accelerated from zero to 60 mph in 9 seconds about a second or two slower than some rival V6 SUVs.

The optional 5.7-liter V8 produces 360 hp and 390 lb-ft of torque and comes matched to a six-speed automatic transmission. With 4WD it is rated 13/20/15 mpg. In our testing a 4WD Overland V8 did the 0-60 drill in 8.2 seconds.

My other car is a 2007 C6 Z06 with 550 hp. Had a little work done to it to squeeze out the extra 45-50 hp Car is scary fast.

Once there is a tune available for this hemi, I will do it. The transmission will shift crisper and quicker not to mention the additional 30-40 hp you'll pick up. I tuned my 2005 WK hemi and what a difference. Returned it to stock when I traded it in.

Why is this? It falls under the 100k mile warranty. I know it's a problem, but it's not nearly as big as it appears.

I'm afraid that is not accurate and may have been the early test car. Recent tests from both engines show much better numbers. Zeroto60times uses various sources to get their numbers and has the following.

V6 Limited = 8.0 seconds 1/4 = 16.2
V8 Overland = 6.9 seconds 1/4 = 15.3

My cousin's Audi Q7 S-line is slightly slower to 60 MPH than my Hemi. We've tried it! Let's try another...

Lexus GS 460 SUV = 6.8 seconds 1/4 = 15.2

So as you see the Overland Hemi is pretty darn quick for a 5300 lb SUV. In fact I'd say that it's power is on the mark for it's suspension geometry. Any faster and it might be dangerous! ;-)

I rented a v6 while my hemi was in the shop getting repaired after some idiot hit me. The v6 Laredo's engine felt like it was going to blow when I floored it. Maybe that particular jeep had been mistreated and wasn't running like it should. Either way, the Overland Hemi that I own and that Laredo v6 that I rented were light years apart. I could never go back to a v6 after having driven the Hemi. I honestly can't believe what I'm reading on here from v6 owners comparing to a Hemi. To me the Hemi explodes off the line and growls deeply doing it when compared to the lawnmower like noise that the v6 produces.
