Quite a few people on this forum have claimed 6.9 seconds for the 11-13 hemi, some with utube footage and a OBD2 interface. I have no idea what the "real" number is or "should" be, but as per my previous post, there are a lot of variables that could alter the times, to the point that each individual set of numbers are fairly meaningless on their own - and I do also include times from so called "real reviews" in the same category.

Don't know how credible autorooster is and where they got those numbers but they sound about right. We know the older 5.7's didn't do 0-60 in under 7 like they claim on this site. It was more like mid to high 7's.
My 2005 5.7 used to do 6.8.

Unfortunately my 2013 5.7L would not even get close to 6.9, it would be in the mid to high 8's.

I agree, too many variables come into play when doing these tests. But at least from what i've
read the ones that are seeing high 6's are 2011's with custom tunes from hemifevertuning. Most owners just seem to complain about the acceleration on the 11-13's. They should be high 6 second trucks from the factory, but the gearing and the transmission are to blame.

There was a guy on this forum that said he raced his 14' 5.7 against his friends 12' or 13' 5.7 and beat him off the line everytime by several car lengths. He said there was a huge difference in acceleration between the two.

I'm sure it did. I'm only comparing the 11-13's

Quick question: Are these 0-60 times done with brake revving, or just tromping on the pedal?

I think it is a combination of gas pedal --> ECU --> engine delay as well as the traction control, especially when going from off throttle/braking to full throttle; when going from light throttle to full hammer down the response is much more instantaneous on my truck anyway.

Cautiously optimistic there might be a module update to help a little, I have the lifetime warranty so going the aftermarket tune option is not really viable.
You can get reasonably close by using the paddle shifter to select 2 and then 1 when coming to a stop and make sure you are at 1 when stopped. Then as the light changes, use the paddles to do the upshifts until you are up to speed and just hold the + for a second or so to get back to either normal sport or eco mode.

The ECO mode also results in an unfortunate delay if you are trying to get around a truck on a [legal pass area] steep uphill 2 lane. Dropping into sport mode is a definite good idea, or just use the paddles for long enough to keep from meeting that downhill bus.

Sounds like you had a real salesman, one that would prefer you be happy with a vehicle in the $50K range as opposed to sticking you on a seat and cashing your check.

My salesman urged me to run his Overland Hemi demo in sport mode after toodling around a bit.

Some sources just plunk their heinie in the seat and push on the gas.
Others may ask the Jeep engineers standing by what the optimal method is without abusing the vehicle.

Several of the former justify their modes by saying they test it as if they owned it--as if they never owned a performance vehicle before in their lives.

I haven't discovered a big benefit using brakes to run it up a bit.
It sure seems to pretty much hit the same timing.
Suspect the good traction and possibly some nannies are conspiring.
I haven't been able to make the tires chirp on dry pavement either, except around corners where they can be coaxed to play a brief tune.

Not quite willing to see if it can be dropped from neutral into drive at higher rpm.

Hahaha! As a kid, I had a friend who would take his mother's big block 1960 Chrysler 300 out. He'd rev it up in neutral to maybe 2500 rpm, push the "D" button on the dash and floor it.....he would burn thick rubber off that left tire for a full block! Thing was a BEAST! I'd like to have it now!

Re: 2014 V8 is weak?

Here is my take on it test drive both what does it matter which one gets from 0 - 60 faster, if you want speed SRT8 or BMW X5 which has 550 horses is what you want, the V8 is a better engine hands down, it is also more expensive to maintain, I have the V6 model in the 2013s and the reason was in those models the Hemi is not good on gas, in the 2014 models the Hemi gets the same gas milleage in the city as the 2013 V6 I would go when I am ready to trade in my model after all the bugs are worked out of those models after what I have read in this forum the Hemi is the way to go, the price is high in Canada that would run you 51k for base model overland or limited

Re: 2014 V8 is weak?

0-60 in 6.8 seconds isn't slow for an SUV that has the weight the JGC has, go with the Hemi, it even has a higher resale value
