The jeep's V6 is rated at 295HP and 260 lb/ft of torque as opposed to the 365HP and 350 lb/ft torque on the Ford Explorer V6. That is close to the performance of the V8 (a little more HP, but less torque), although the Ford is also slightly lighter. It is hard to compare exact 0-60 times, but it generally appears the Ford's V6 is over a second faster to 60 than Jeep's. That definitely surprised me. I do wish they had an 8-speed and am disappointed that it only has six, so that is a valid point - but it sure doesn't seem to affect the pick-up.

My mistake. Most Explorers come with a 3.5 V6 (no turbos). The Acadia, Traverse, Enclave have a 3.6

The Explorer Sport (and Platinum) have the EcoBoost you're referring to. It's geared a lot different, lower ratios. The GC has always had tall gearing and a tall ratio unfortunately.

Re: First impressions of 2016 3.6L Pentastar

At the risk of being flamed and jumped on , I test drove a 2015 V6 Summit, and found that I had to get on the pedal to wake up the engine, as there was a brief lag and hesitation as the V6 surged RPMs and the tranny correspondingly downshifted in response to throttle inputs. Overall, I found the V6 to be rather uninspiring for a true SUV with a curb weight of nearly 5000 pounds. (Add in kids, mother-in-law, dog, and luggage...)

I went with the 5.7L Hemi V8. I commute about 530 miles/week (plus city driving) and with Eco-Mode on highways I am averaging 21+ MPG, which is actually better than what I was getting with a V6 AWD Acadia Denali and a V6 AWD Acura MDX. At any rate, I am very happy with my decision to go with the V8 engine.

Among those who are happy with the V6, please understand that I am in no way trying to pee on your parade. That said, if you have the opportunity to test drive both the V6 and the V8, I would urge you to do so and then decide for yourself.

First impressions of 2016 3.6L Pentastar

The beauty here is that the GC has an engine that caters to just about anyone. The Pentastar in latest generation is quite refined and descent fuel economy for it's size.

The GC is one of the few cars left that offers a v6, v8, Diesel and SRT btw.
Something for everyone.
I've driven all and owned the Diesel and v6, the latest v6 is not a powerhouse but MORE than adequate for this SUV

The v8, Diesel and the SRT Are not inspiring (to me) enough to really make a difference that blows my mind, but quite a range of choice!!

That's true kitty cat there's not a drastic difference in power or mileage between the v6 or v8 but whats also nice is the cost between them to upgrade is cheap. I know it may have gone up a little but when I bought my 2014 GC to move from the v6 to v8 was only $2599 and that included the added ELSD which is a a several hundred dollars option on its own. I remember thinking at the time how few SUVs even offered a v8 anymore let alone it only being 2k to upgrade to it on a 55k vehicle. Of course no one pays anywhere near invoice so the true cost was even less than that. Wasn't much of a thought there to me but it's good they have an engine for everyone and I hope the GC never turns into one of those SUVs that offers one engine take it or leave it and looks like a minivan

I always love hearing these high average numbers "on the highway" Have you calculated your actual MPG from tank to tank? Not using the car's calculation but gallons pumped and miles traveled for a few tankfuls?

I have and routinely get 20-22 mpg on highway driving with the Hemi. My EVIC is actually pretty accurate over time. That said, my next vehicle will not have a big V8 because at that point, my need (towing) will no longer exist.

Very tall gearing in 8th on the highway and MDS makes for some impressive highway mileage no matter how you calculate it. My EVIC is about 1-2 MPG's higher than calculating the only true method - consistent fill ups dividing miles by gallons consumed.

Re: First impressions of 2016 3.6L Pentastar

Want to add my $0.02 here.

I've now driven the 3.6L V6 second generation three times, twice in Grand Cherokees (one base Laredo, one Limited w/ Lux II) and once in a Durango. Perks in being a National Emerald Executive member.

I thought the motor worked well in the WK2s, but in the Durango I thought it seemed to struggle. The 845RFE doesn't have the same 1-2 shift lag that my 8HP70 does. The shifts were crisp and precise, and when I kicked it down at highway speed it happily dropped from 8th to 5th or 6th. I thought it kept the engine well in its sweet spot to provide good acceleration when necessary. Even had the AC running at 68F and it didn't seem to miss a beat.
At 70mph its turning about 1800RPM. Not bad, I think.

However, the auto stop-start is something I started to find annoying. The time between vehicle stop and engine shutdown needs to be lengthened. I would pull into a parking space and keep my foot on the brake. The engine would turn off within two seconds before I even shifted into Park. I'd shift into Park and the engine would restart, and then I would turn it off. A waste of a start cycle, IMHO. Five seconds would be more ideal. Stop and go traffic it was just maddening and I ended up turning the system off.

I also noticed a restart shudder transmitted throughout the cabin when the engine restarted.

The new hybrid power steering system I really like. It does make me feel connected to the road. I test drove a 14 V6 and hated the steering.

For most people, the second generation V6 is probably a good choice. For me, I'll stick with the V8. The sound the V8 makes in the cabin is just addicting..

agree getting 21 mpg averages highway cruising out of the hemi is not some lofty number, hell the 2016 4x4 5.7 GC is rated at 22 mpg highway. even getting 24 mpg out of it is not black magic set your ACC at 65-70 and go. and the evic on this vehicle is actually highly accurate. there is a thread on here where a guy suggested doing hand calculation on mileage over the span of 5-6 tanks not one, I tried what he said and came up with a .3 difference which was slightly more than the .1 or .2 he was getting. regardless you don't get much better than that with any evic. I think many people just discount the effect the MDS in 4 cylinder mode has on a highway cruise at average speeds. here is a trip from a few months ago there really is no magic to it with the 5.7 and I use 87 octane.

Re: First impressions of 2016 3.6L Pentastar

silver', I think that regardless of how one calculates the highway fuel economy...EVIC or manually...it has to be over a period of time and miles, not per tank. There are too many "little things" that prevent any kind of accuracy otherwise. The EVIC has a "mileage window" so you have to drive enough miles to clear out any "local" travel and get to where you're at entirely highway miles. My best mileage performance is either long vacation runs or when I take a business trip to visit a customer in Parkersburg WV a few times a year...a nice thousand mile round trip. By the end of that run, I'm pushing 22mpg and yes, if I manually calculate it, assuming I want to buy expensive PA gas at the end of the trip (I prefer NJ prices ) that number isn't much different than the EVIC. By the same token, multiple tanks are required to get an accurate reading for manual calculation because it's pretty much impossible to fill up to exactly the same point each time...it can vary by more than one might think due to variances in the way the pump shuts off, etc.

Jim,

If the NJ politicians have their way the NJ gas prices will be higher than PA with the proposed .23 gas tax increase. Not something I'm looking forward to as a NJ resident.

Re: First impressions of 2016 3.6L Pentastar

I didn't know there was a power, or torque difference between the '15 and '16 Pentastar V6 in the Grand Cherokees. My wife test drove a '15 last week. Although it had noticeably more power than her '09 Grand Cherokee with a 3.7 V6, it didn't seem to be anything to write home about. We thought about looking for a GC with a 5.7 V8, but decided to get her the SRT Grand Cherokee instead. The dealer made me an offer I couldn't refuse! He should, I just bought a Challenger Hellcat from him two months ago!
