Hemi or Pentastar in 2014

Hi, looking at getting a new 2014 GC Limited. I have a 2008 Overland now with the hemi. The MPG was not impressive on my 08. Have they improved the Hemi much since 2008? I also see the 8spd/3.09 Ratio as the package, wondering how that does for mpg and overall performance.

Anyone have some real world mpg on the Pentastar vs Hemi in the 2014's with the 8spds? Or overall thoughts on which way to go. Thanks!

First its not a hemi. Hemi is still a cast iron block with dual plugs. Chryslers V8 is very old school technology compared to Chevy's previous generation V8 and Ford's previous gen V8. Ford's Coyote V8 and Chevy newest small block and light years ahead of the so called hemi in the technology and output.

Do you tow? Only reason for the V8 in a GC is for towing. Real world in my 2012 V6 I am getting 20-22. If I had a 2014 I figure I would getting 22-25mpg. This is everyday mpg with commuting and trips to grocery store.

I have the Hemi and I average 19 mpg about 50/50 mixed city/highway. I went on a road trip down to Oregon and back, and I averaged 23 mpg on the freeway with the A/C on. I'm very happy with that mileage.

The Hemi has a ton of torque and the Jeep moves effortlessly with it. I initially wanted the V6 for the gas mileage. But when I drove it, I felt the V6 struggled just to keep the Jeep moving.

If you can live with 2 mpg less real world economy, and like the idea of having plenty of power in reserve when you need or want it, I'd get the Hemi.

In my short experience, I am very happy with my decision to go with the hemi. So far 18-19 in town, 22-23 highway. Having the extra power/torque is a bonus. With my 2013, having a $1500 rebate on the hemi made it an easy choice.

First off do not listen to Dave, he says that in every thread he can fit that in.

My wife has a 2014 with a v6 and it is just fine, especially in sport mode, I wish she had the hemi just for the fun factor but love the fuel mileage, everyday driving she is getting 21 or so mostly city with some highway. She has about 4500 miles on it and hasn't had a tank yet with a average below 20. I just got a 2013 Ram with the 8 speed and hemi though and I am averaging 15.5 though 1200 miles, and that is mostly highway driving. I towed my dad's boat last weekend with it and you didn't even notice it on the truck, I did the same with her jeep and you could definitely tell it was back there, it didn't seem to struggle, but you knew it was back there, I got about 13 average with my truck pulling it, her jeep was about 14. The boat is only a 17' Lund, but it does weigh a decent amount.

Have had a 07 Hemi, 09 Hemi, 11 Hemi and now for the last 9 days a V6 Overland. My prior Overlands with the Hemi's averaged 15.5 mpg combined with about 20 on the road included in that. My 14 Overland with the V6 and a little over 700 miles is at 21 mpg and burning regular. My towing is limited to a few trips with the boat per year to put in a mooring an bring home again, but if I were doing a lot of heavy towing it would be the Hemi, my Hemi's excelled at towing. I expect better mileage on the V6 after adequate break in miles and I am thrilled with this 14 Overland and the V6 with the 8 speed transmission. Same roads. same driver and I am getting over 5 more miles per gallon and regular not premium gas required. My opinion is the V6 has ample power but if I were towing I would get the Hemi and pay the extra gas cost.

Mild thunder- Did your 08 have eco mode where it went down to 4 cylinders. As long as you don't have a heavy foot, it's in eco mode most of the time running on 4 cylinders, not 8. 5000 lbs is a lot of vehicle to move around with 290 horse. I opted for the hemi and am happy I went that way.

If you do a forum search, there is a big thread on this which I looked at before actually buying my GC.

Our 08 does have the ECO mode. I've never seen better than 20mpg hwy unless we were doing 55mph in the right lane with a 25mph tail wind. usually its around 17-18 best.

My V6 hasn't let me down once in the almost 4 months I've been driving it. The 8 spd. works great. I'm getting about 8 mpg more than I got with my V6 Buick Enclave, so that is all good. Nothing against the hemi, but I don't do any heavy towing, so the Pentastar suits me just fine. I find absolutely no problem with power in any driving situation, and I haven't had it out of eco mode for quite some time. It's not a race car, but that's not why I bought it. It's a fine piece of modern engineering, and I'd buy it again in a heartbeat.

X2... Only I experienced as high as 28 MPG on the highway and got 25+ fully loaded going 80 down the interstate in Utah. I'd never go V6 after driving the Hemi..there's no upside.

My wife has a 2012 with the hemi, she has just over 62,000 on it. When I drive on the expressway I average low 20's but she is a much smoother driver, and keeps it in the ECO mode, she averages 24/25. She loves it and wouldn't trade it.

My MY12 with the Hemi averages about 16 in general rural driving and typically 20-21 on the highway, although I got 24 last week on a 1000 mile round trip to Parkersburg WV at a steady 65 mph. That said, for many folks, the V6 is a very good choice. Towing and "performance oriented driving" will benefit from the Hemi, however. I do tow on occasion and that's why I opted for the larger engine. The diesel option should be available for order this Friday, too...giving a third option to consider. (upper trim levels only, however)

I still call bs, almost everyone else posts that they are getting in the lower 20's,upper teens with theirs, and you are getting 25+? Or even 28? If I can just barely hit 20 in my ram that is rated higher for mpg's, how could you manage 28? Running 55 my wife's jeep can just barely get that, at 70 you are down to 24, maybe 25 mpg's.

Of course it's BS. but hey, I experienced 99.9mpg when i left off the gas and let it roll going down a hill. Beat that Prius!

i have the V6 and it has more than enough power (45-65mph to merge on highway is slow, though) so unless you're towing heavy things, i see no reason to get a bigger engine.
