I don't have a 2011 V8, mine's a 6. All I can tell you my neighbor had a 2011 V6...he traded it on a 2012 V8 because the 2011 was too lethargic. He just traded the 2012 V8 in on a 2014 V6 with the 8 speed. When I asked him if he missed the V8 he said the 2014 6 felt better around town than his 2012 V8, and that this Jeep was finally the Jeep he wanted. Remember...this guy got killed trading the 2011 6 in because of the motor.
I am glad to hear your neighbor is happy with his jeep. They are meant to be enjoyed and the 8speed is the tranny the v6 always needed no doubt.

2014 v6 0-60: 8.3

They aren't the same publication but I couldn't quickly find a 2011-2013 v8 from Motorweek and I couldn't find a 2014 v6 for Motor Trend. Motor Trend seems to be more interested in the diesel for the 2014. Although, I think you can assume the times will be similar between the Motor Trend and Motorweek.

That laughing smiley generally indicates sarcasm btw. The times posted by AOL are silly.
2 completely different magazines. Motortrend and Car and Driver use similar equipment. The tests range from 7.3-7.8 for the pre 8spd V8. The tines for the 8spd V6 were 7.5-7.7 I would call that a dead heat. Where it really shines is that the passing times for the V6 have been quicker. Every magazine called the old V6 slow. They also all called the Hemi a disappointment. They said it could only match the times of competitors V6. It was all do to the crappy transmission. Now the new V6 has the best transmission on the market. It makes it equal to its competitors, which makes it equal to the old Hemi. Just go trade in for an 8spd. Then you can boast about your Hemi.

How are the gear ratios the same? You don't understand anything about cars and trucks. If you did, you would see over the years where this affected many vehicles. Bad gearing equals bad acceleration.

Herr is a good real world example for those who don't get the difference gearing and multiple speeds can do. My first car that I got in 1987 was a '69 Firebird with a 350 2bbl and a 2spd powerglide. It had 2.56:1 rear end gears. The first time I ran it down the 1/4 it needed over 17 seconds. I changed the transmission to a 3spd TH400 and a 3.55 rear. It then ran the 1/4 in 15.8. 1-1/2 seconds just because of gearing and the trans.

Yes, I am dammit, but thank you for asking.

It is also a near luxury, or a luxury SUV when equipped as such, and a great cross country hauler that on wide open western roads drives very much like an older Jag sedan.

Umm, why not? Good brakes, great handling. With halfway decent tires will keep up with any minivan, and when the weather gets bad with appropriate tires, can keep right on trucking.

The feeling of "effortless power" really transforms the day to day driving experience of a vehicle.
I tried the 2014 V8/8 Speed, but it badly failed the high altitude steep mountain driving test.

It feels pretty zippy around flat areas, cruises nicely, and quietly.

But, when there is a short passing lane and a sleeping Volvo uphill at western highway speeds, it just didn't have the passing ability at western speed limits.

Out of ECO mode, the 8 speed does hold lower gear a bit longer, which is quite handy for passing on two lane mountain uphills.

Other than that, i honestly consider the non-ECO a bit of a pain in the tookus for ordinary driving, mountains, flat, city, etc. It does drop to aero height and change torque front/rear to more rear, but unless I'm over 55 mph or really having fun around tight mountain curves [now, unfortunately mostly washed away] the ECO mode works very nicely. And does allow for an overall mpg of about 18 since original delivery.

Sometimes yes. But that still doesn't mean the '14 V6 is as fast as the older V8.

Its more the case that bad torque/horsepower curve combined with poor gearing for that engine's curves hurts performance--which would affect the older V6 model much moreso than a fairly high performance V8 even if the V8 were limited by gearing.

Now, for your benefit, since you are ignoring Carroll Shelby's cubic inches rule, why not remove that 350 and put in a 421?

More gears helps an engine with a very narrow torque curve and peaky horsepower far more than it does a larger engine with a fatter torque curve and broad power band.

My old 66 SS 427 [taken to 466 for grins] with a 4 speed and 3.07 rear end would have eaten that Firebird for lunch, even if launched in 2nd gear--but it was never stupid enough to take on a Keith Black Mopar 426 with 4.56 locker rear.

This is just beating a dead, slow, V6 horse, even if it is wearing 8 horseshoes.

Please enlighten us on the differences between Motor Trends and Motorweeks testing equipment and (THIS IS THE BIG ONE)how the differences would generate a substantial discrepancy between times. Specifics would be best. This is the internet after all.
Also, 7.3 (v8) < 7.5 (v6) is not a dead heat.

You are aware the 11-13 v8 had a 3.45:1 rear end? The '14 v6 has a 3.45:1 rear end. 3.45:1=3.45:1

Are you sure a comparison of going from a 2 speed to a 3 speed with large increase in rear end ratio is a good example to use in this circumstance?

I'm driving the V8 as a daily driver now so I'm not sure what you mean the V8 is a dog, are you comparing it to a corvette?

The diesel may actually be a better option for you especially in the mountains.
