I can say a few things about this traded my wife's 07 GC SRT for 14 limited v6. You can't compare them in any way but I will say the v6 8spd shocked me how it feels around town and hwy. I don't find myself wanting more power unless mustang,camaro, vette, goes by then I want to kick myself... SRT ran 12.6-12.8 depending on weather. I will go run the 14 down the track in a few weeks when it gets cooler here. I would be surprised if it runs under 15.9

I keep seeing all the V-6 guys over the years try to justify not getting the Hemi by bragging about what appears to be in real world driving a few, 1-3 MPGs advantage for the most part. With the way I drive, it would probably be less.

There hasn't been a lot of Hemi testing but Car and Driver compared the 2011 Hemi vs the LR4. The Hemi did 7.3/15.4@90. They did passing from 45-65@4.0 sec. That is better than your 8speed,6 cyl, 7.5/15.7@90. The 6cyl 8 speed passing from 50-70@5.2 sec. Not apples to apples, but again, your not looking in you rear view mirror at me.

For me, I would never buy a 4x2 Jeep. Defeats the purpose of a Jeep IMO. I also would never buy a 6cyl over a V8 in general, if they are close in price and didn't need a 6cyl for some special reason/purpose. Too each his own my Jeep brother.
The car and driver I read was against a pathfinder, KIA Borrego and something else. The Hemi overland needed 15.8 for the 1/4 and 5.3 50-70 mph. That's apples to apples. Both times slower. I'm not saying the V6/8spd combo will smoke it. But it is better all around. Sorry.

Re: 2014 V6 versus 2013 V8

Not apples for apples. The test comparison you reference shows the vehicles in possibly 114 degree heat or up in the mountains. If true, absolutely effects performance times (I hope you don't try to argue that point). The test sheet doesn't say what elevation or temp that I could see. Maybe you can find it. None the less, ultimately head to head at the same time settles it and all of this is becoming silly. We are talking about a few tenths here in some average performing vehicles.

The Trucktrend test that was referenced in this thread had the 8speed, 6cyl at 7.7 0-60. Still slower than the 7.5 of the old Hemi test you mention.

Ultimately, I wouldn't trade my Hemi power plant for a 6 cylinder just because it has a 8 speed. Trucktrend sums it up:

As impressed as we were with the V-6, the V-8 was even better. The combination of 360 hp and a much torquier 390 lb-ft -- which peaks at 4250 rpm -- took care of all of our minor gripes about the V-6. Those who want a little more fire under the hood should be very happy with the 5.7-liter, even if it means fuel economy goes down to 14 mpg city/20 highway. We admit that's a big jump, but having to choose between more power and more efficiency is why Jeep offers multiple engine options. Steering feel was excellent in both SUVs.

I think it is safe to say we both prefer our current vehicles over each others which is good. Cheers.

For the OP. Yes the new V6/8spd is just as quick as the old Hemi/5spd. Just think about it in terms of riding a bike with 5 speeds vs. something with 18 plus. Just think about how easy it is to pedal away quickly in one of those lower gears. On the same note, the new Hemi/8spd is quicker as well. Finally makes it what a V8 should be. So every '14 Hemi will blow the doors off the V6.
Um...obviously a 2014 V8 will be faster than the 2014 V6. But my comment was the 2013 V8. From what I've read, the 2014 V6 is quicker, not just as fast. I'm not looking to drag race because, quite honestly, they are both slow. I'm just surprised that the 8-speed makes THAT much of a difference to put the 2014 V6 ahead of the 2013 V8.

I remember back in high school my buddy had an old Chevelle from the early 70s. It sounded fast and it even felt fast. Then he took it to drag strip and couldn't get it into the 15s. LOL. So much for feeling fast. I think it was the sound more than anything. What a great-sounding engine that car had. Sounded like a million bucks, but made the car go about as fast as an old Ford Escort.

Re: 2014 V6 versus 2013 V8

Are you all that much in a hurry?

It's a UTILITY TRUCK !!! A good off road one at that.

Not the best thing to be speeding around with, with any engine.

Re: 2014 V6 versus 2013 V8

Its not about "going fast" its about the engine and the vehicle overall not feeling lethargic or underpowered at times. My 2011 V6 does at times, the 8 speed really has helped that engine be all it can be.

The feeling of "effortless power" really transforms the day to day driving experience of a vehicle.

Re: 2014 V6 versus 2013 V8

Shut eco off or use sport mode.

My understanding on the v8's it's similar because it still tries to maximize mpg.

Neither will feel like what it could do in eco mode.

You don't have an 8spd. though. The articles comments don't apply to your Hemi. The quote for your year was this
" the Jeep’s fuel-inhaling V-8 returned near-V-6 acceleration times."
It comes down to the fact that a V6 8spd will run side by side with your Hemi. It will probably beat you in a roll because of the superior gearing and much better transmission programing as well. It won't be drastic, but it does make your Hemi with its 19 mpg highway irrelevant. If you want to go trade up for a '14, then that is a different story. You were the one who brought up that your Hemi would still smoke the new V6 from a roll. I'm just pointing out that its not true. I've yet to find myself in an all out drag race, and I've yet to find that I didn't have enough power to do what I needed. It seems that ever since the instrument tests of the new V6 came out, every '13 and earlier Hemi guy have been knocking it. I don't get the insecurities. I tested the Hemi as well. It was fun. Did I need it? No. I'm happy that I have gotten 25mpg or better on some highway trips. All on regular gas as well.

JohnC,
Having owned a 2011 Overland V8 (Retired) and Now a 2014 Summit V8. I agree with you about the bad gearing on the 11 HEMI but once the 2011 got into its sweet spot the 2014 V6 couldn't get close. I test drove the 2014 V6 multiple times and the last time I test drove the V6 I had a hard time trying to pass a Van. I also noticed that the V6 took some effort to get up hills. I do believe that the 2014 V6 is way better than the 2011 V6 but I don't agree that it’s faster than the 11-13 HEMI especially in sport mode. The V6 power is all up top and about time you hit that power curve who ever you were trying to pass is either gone or your tired of the V6 whining in your ear. I did notice that they gave the V6 a little bit more power off the line but performance everywhere else is lacking power until you get high the RPM range. I think the V6 gets the job done as a daily commuter and I’m glad that jeep offers the option to entertain various buyers.

I'd bet money it was in eco mode.

Remember that on the 2014 you have to TURN OFF eco mode. I drove the 2014 V6 and power is pretty effortless in all situations. Your description reminds me of how the vehicle drove in eco mode.

I find it drives more crazy in those situations with ECO mode on.

Problem going up a hill or Passing. No way.

The problem is in Eco mode if you drive it "Gently" it Lags. But if you stomp on it. It WILL GO. Search for "Whiplash Mode" == "Eco Mode".

It will drive much smoother with Eco Mode off.

But either mode will pass or climb a hill just fine.

It's just that Non Eco Mode will be less "Eventful" in doing so.
