Re: V-6 or V-8, regrets?

The great thing about this thread is that with Jeep you get to chose between 2 really good engines, both of which offer great driving experiences.

V-6 has plenty of power, gets the job done, and is pretty frugle with gas for a 4,000+ vehicle.

V-8 has tons of HP and Torque, and with displacement on demand gets pretty good fuel economy when loafing along, with lots of reserve torque for towing or hot footing around.

Hard to go wrong with either on them, however the debate runs down to pay for play.

Re: V-6 or V-8, regrets?

^^^agree. I was torn between the two for the longest time, but what it came down to is my daily routine. I either drive 4miles (in town driving) to work each day or 125+ miles when going to out of office stuff and the Hemi did not make much sense for either situation. I tow just a handful times a year and was pleasantly surprised with the v6 when test driving.
It's been 8days of city driving thus far and I'm right at 17mpg which is great, IMO, especially with it being new as well as the winter gas we have here in MI now.

Re: V-6 or V-8, regrets?

I love my HEMI.

I traded in a 2005 V8 4x4 Limited Toyota 4Runner for my 2012 V8 4x4 Overland JGC. One reason I didn't even think about getting a 5th Generation 2011/12 4Runner was the lack of a V8 engine option.

I just couldn't see going backwards in respect to engine power.

And the Hemi gets okay gas mileage if you keep your foot out of it. But then there is still the option to really punch it and feel the thrill.

And I don't tow anything; but I do haul...

haul a$$!

Of course, for folks with families, Grandmothers & Grandfathers, or those that drive like Ms. Daisy, there is no need for the higher performance the V8 offers.

Re: V-6 or V-8, regrets?

unless you're referring to the SRT, I'll jump in a real sports car if I feel the need to haul a$$

Re: V-6 or V-8, regrets?

So far the V6 has served us perfectly in many types of driving, including long trips. Haven't hit the mountains yet, though.

Re: V-6 or V-8, regrets?

what's the factory performance figures of the 6 and 8?

0-60 mph, 1/4 times?

Re: V-6 or V-8, regrets?

Call it weird but specific to this topic was that a gas attendant asked me this question today. I have the Hemi engine and while stopping for gas there was a like model across from mine but with the V6 (Penstar). The attendant (to be honest, I believe the owner) said that his wife was looking at a MY11 Ltd w/ Hemi but was concerned about the fuel economy. I told him that I range between 15-17.5 mpg. The V6 owner was 19-21 mpg. Over a 500 mile range the difference would 5 gallons or $18 @ 3.65. Significant, yes. Do I wish the Hemi was more fuel efficient or had the throttle response to correspond with the low economy, yes. Do I regret getting the Hemi, no. Would I do it again, yes.

The Hemi just felt and sounded better. For me, I would've been unhappy with the Penstar. However, being fair, I can see the appeal of that powertrain. I also felt more comfortable with a powertrain that had history (i.e. Hemi).

As always, Hemi vs. Penstar, there will be strong opinions for each side, it is best to test drive both, look at the economics and form your own opinion.

Re: V-6 or V-8, regrets?

yes, I think with certain driving conditions the extra fuel with the Hemi is not a big issue, but i had a Hemi model for two days a few weeks ago and I got around 11mpg(winter gas) with all in town driving and once I got my V6, driving the same streets for a few days got 16.8mpg which I find significant. neither engine was broken-in, but I found it interesting that the V6 had hat much more of an increase. Also did the same thing driving to and from the dealer (1hr trip) and the difference was 19.1vs 22.8...same highway, same speeds. Again, not huge but thought it was worth noting.

I definitely like the grunt of the V8, but i also like the lighter nimble feel of the 3.6. IMO, it's a much tougher choice with the WK2 then the previous models as the penstar does pretty good when needed where as the old 4.0 and 3.7 were very sluggish. I had to go with the V8 in my previous jeeps, but did not feel like it was necessary this time around. However, I was ready to go with either if it had all other options i was looking for.


I thing times are all over depending on the review, but i recall these numbers when reading one write-up:

5.7L 7.0sec 15.3
3.6L 8.1sec 16.2

I think motortrend reviews stated the 0-60 at 7.5 and 8.5, respectively.

Re: V-6 or V-8, regrets?

Hmmm I was expecting to get much lower readings in my hemi but maybe because I still haven't broken in the engine yet and I've been light on the throttle I've been able to achieve these numbers.

I mainly do city driving with stop n go traffic, most of Kuwaiti streets are either stop n go or pretty much empty. Granted you'll notice our winter is great, we get early twenties late teens during the afternoon and in the evening it's around the early teens (12degrees on average). This all of course does not account wind chill but regardless, I am not going to complain after coming here from Canadian winters (I like being able to feel my body thank you very much...though I would have loved the chance to take this Hemi through some snow for sure...)

Anyways.

I think that's quite impressive for the Hemi.

wouldn't that be Kilometers and not miles? so it's on par.

Re: V-6 or V-8, regrets?

12mpg...that's what you'd probably see over here during the winter months, maybe less with majority city driving.
