I just rolled 1500 miles in mine and have not reset the MPG. 19.4 is what it says right now. Mix of city/highway.

Re: V6 Grand Cherokee...The good and the bad?.

I think the gas V-6 with the 8 spd is the perfect drive train for this Jeep. It's my first SUV, but I've driven mini vans in the past and my other car is BMW 335 with sport suspension and a twin turbo 6 making over 300 hp. I think the gas V-6 allows you all the acceleration you need to safely drive it at high speed, including passing, and merging. Its won't accelerate like my BMW, but it doesn't handle like one either. It still accelerates without a lot strain and noise when I want to go from 60 to 80 to get around a truck or another slower car on the highway. I can safely go from a stop through an on ramp to get into a opening on a highway. I have to plan a little and make sure I know what is coming up behind me, but I have never felt like I couldn't get the Jeep safely onto the highway. I have driven it twice from N/VA to Florida and once from N/VA along the Pennsylvania turnpike to Pittsburgh and Dayton Ohio. To me, its the perfect highway cruiser. I wouldn't try to drive it on the Tail of the Dragon, but but for 95% of the way my wife and I use it, it's perfect. I sometimes see someone in a JGC driving aggressively in a V-8, cutting people off and forcing themselves into space on the highway, tailgating and driving like a nut case in a sports car. That will work until they have to hit the brakes in an aggressive turn and find out what trailing throttle oversteer means, when they start going sideways until the tires regrip and they roll it or get launched into a guardrail.

Re: V6 Grand Cherokee...The good and the bad?.

I went from a 2014 Hemi to a 2015 Pentastar V6. My mileage is obviously better, but nothing to write home about. Only a small difference.

The V6 is plenty adequate. Power delivery is smooth and more than enough in any situation. I'm a very aggressive driver. And I find it to be very decent. It's not 'fast' but it doesn't ever give me the impression that this thing is slow. Which is really what matters to me.

My verdict is: Get the Hemi if the price isn't that big of a deal. It's something like a $3,500 upgrade. The thing is, my 2014 with the Hemi had such a better transmission. The Hemi is known to be far more reliable, and mine was. I don't regret getting the V6, but I'm already wanting to trade it in on a High Altitude EcoDiesel.

Re: V6 Grand Cherokee...The good and the bad?.

why not go to a dealer and drive one for a day, any dealer worth their salt will throw you the keys and take a nice test drive.

Re: V6 Grand Cherokee...The good and the bad?.

The V6 is an awesome engine. Sure, if gas was free, I'd have an SRT Hell Cat.
If they made a V6 SRT I'd buy it in a heart beat. All the trimmings of an SRT with the V6 motor. I like the V6 as much as I did the 4.0 Straight 6 of earlier years (also a great motor).


V6 has PLENTY of power. It is said the specs for V6 8 Speed, match the Spec's of a Hemi with the 6 Speed.


It has a very nice purr when you step on it. Test drive one.


I average 20-24mpg and get as high at 28mpg on the highway (Summer).
It really depends on how much of a lead foot you have.
If you only get 11mpg now, you may end up at 18mpg with the V6.


Early V6 transmissions had issues. Which are now long resolved.


Get an Overland with Adv Tech (do your homework, it is well worth it according to many THAT HAVE IT, very few regret having it). And maybe the H/K radio too.
If you can swing that. They are all pretty good deals at each trim level for what you get per dollar.


I might trade mine for a 2016 Summit next year if I can get a good deal on trade.


Passing, getting on highway etc. with V6 I don't even understand why people ask.
Now if you asking how fast can I pass or get on the highway with 5000lb load, then sure ask away. But with the Jeep only it's ridiculous. How fast do you to go that the V6 isn't enough? I just don't get it.


A better question might be, that is rarely asked, is how fast can you STOP !!
This Jeep is heavy. And it can take a little bit of time to stop.

Re: V6 Grand Cherokee...The good and the bad?.

I chose the v8. I drive in stop n go city traffic (Chicago) so only getting about 11-12mpg typically. Recently did a highway trip (about 100 miles one way) and averaged just over 22, so not too bad.

When I test drove the v6, it felt a little under powered imho. Not dramatically and I am sure it is fine for most folks. I'm of the mindset that I rather have the power and not need it than need it and not have it.

I was also a little nervous getting the v6 given some of the reliability issues I read about. I didn't feel the slight MPG gain of the v6 was worth giving up the excitement of the v8, nor worrying about the reliability.

Re: V6 Grand Cherokee...The good and the bad?.

What is this "gas mileage" thing you guys are talking about? I don't think my SRT came with that option.

My main concern was the get up. Since you're in the area, you must understand what I mean. Trying to merge onto the Deegan when cars are flying by in the right lane. I don't want to put her into something dangerous. I'm impressed with V6, 8 speed combo in our 300, but I figure it weighs close to 1000 lbs less than the GC. I plan on nice long road test.

Thanks again for your reply.
If you are worried about NYC area merging speeds, get the Hemi... or an SRT. I used to hate merges even with a solid lifter'd 427 in that area.

Weekends if highway should be near 20.
Mixed 0-40-50 mph commute, a bit of 70-80 mph freeway and a lot of 20-45 mph steep mountain roads the 8-speed in the Hemi can yield just a tad over 18mph once broken in.
For bad merges, quick kick to sport mode helps, as it gives you more throttle control over speed, where you may need to back off and get back on gas, than normal mode does.

Downside is that midgrade is recommended for the Hemi vs regular for the V6.

Some folks have complained about the transmission in the V6 compared to the one in the V8... I don't recall anything from a couple V6 rental instances, YMMV.

The ELSD for the V8 is better, but either model is a great snow vehicle with proper tires.

The nice thing about the V8 is that it is a very well-tamed engine. You can loaf along with the texting commuters, slow trucks, etc. and it just relaxes and trundles along.
It doesn't load up, start misfiring, blow chunks, at all... If you have one of those nasty short merges into traffic it can do that, then go right back to relaxing and enjoying the drive.

The V6 is no slouch, but it is also no hemi. You don't ever have to really stand on it for pretty much any traffic situation--although if you do, the 8 speed may surprise you with mileage higher than the older hemi's could.

Re: V6 Grand Cherokee...The good and the bad?.

Thanks everyone for the very helpful replies. Basically sounds like we can't go wrong with either. So I'll let her test drive each to see which she feels more comfortable in. We might run into a problem as we didn't see too many Hemis the last time we searched Jeep(com), and she has her heart set on a Overland with the Indigo/brown interior.
