How to achieve the factory 0-60 with Auto

I've tried off and on over the last month or two to do more 0-60 runs using track apps on my '13 GT, but I'm not seeing better than 5.1 seconds. I've tried drive, sport mode, and sport mode with manual shifting and various throttle response from just full gas pedal to holding the brake and revving a bit in drive and then letting off the brake. The car is pretty much as stock as can be, is this typical or am I doing something wrong here?

Just kind of disappointed I can't get the factory numbers, 5.1 is quite a bit off from 4.5 and I sometimes wonder if there's something up with mine. I'm assuming I have the 3.15 gears, so is that plus the factory tune really causing the less than impressive times?

Well, it's not that far off... You're talking about .6 seconds and a lot comes into play. Tires, surface, ambient temperature, elevation, driver weight, and a host of other things. Unless you are competing, I wouldn't worry about .6 seconds. Sounds like you car is fine...

I do not believe those timers are accurate at all. I remember only getting 13.0 and rarely 12.9's. Went to track (VMP tune only) and ran 12.45,12.47,12.51 all back to back. So that was the end of using the performance timer. I'm auto 3.15's too.

too many variables with track timer in the car - Altho I can say when I used it just for fun before I modded the car --with a good launch on street tires(i.e. no spin) I was right around 4.5 - this is a manual 3.73 gears

First of all, turn off the TC/Advance track completely. Rev the engine to 2K, roll in the gas and release the brake simultaniously.
Applying the gaspedal is not as easy as it sounds. Too fast and you just make smoke, not fast enough...****** time.
I didn't got mine below 4.6 sec. It just takes some practice.

Also, the testing is usually done with 1/4 tank of gas or less. One driver that weighs about 120 lbs. and ideal temperature and surface.

Well I sure haven't tried the low gas tank thing (I never really thought that made much difference, but I'll give it a go). It seemed to me like the manuals more easily get close to the factory numbers, assuming the driver shifts well and doesn't get too much wheelspin. I wonder if the 4.5 second time was with a manual or auto? I usually did leave the traction and assists off, don't usually get too much wheelspin. I'm using the factory Pirelli tires and usually tried the runs after driving the car for awhile so the tires were warmed up. I thought because of torque converter lockup it's better not to load the engine by giving it some gas with your foot on the brake and to just take off from idle? I can't remember all the RPMs I've tried that at, it's been a while since I tried another run due to weather conditions. I'll try to record it with my camera instead of using the track apps the next few times.

I feel like personally I'd get better numbers from driving the manual, but that's just a feeling. And I thought the automatics were supposed to be as simple as stomp the pedal and go

A MT will give better 0-60 times and 1/4 mile times, up to a certain performance level.


Many magazines got 4.4/4.5 0-60s out of Brembo/Track Pack 6SP MT/3.73 gear cars. Owning one, I'm very certain that those times are not hard to do at all, especially once you tune your car and are proficient with a manual transmission.


I highly doubt an automatic car will do much better that 5.0 second 0-60s, until serious power mods are in place.

+1 on a lot of variables. First time I did it with a few mods and stock tires, 4.9. Second time doing it, with boss im, different cai and cat deletes, 3.15's and stock tires, 4.4. My 0-30mph was a 2.1.

Hmm, so I guess I need a tune to do better than 5 sec? I thought automatic cars these days (particularly performance car autos) had pretty much hit parity with the manual versions, so I really didn't think too much about the performance capability being any different on the auto vs the manual in stock form. Is it more down to the gear ratio, or just the flat out ability of how quickly the auto can shift? I have a friend who still insists that automatics are all just as fast as the manual version of the same car, but all I keep seeing now that I look is evidence showing the manuals besting the autos unless they miss a gear. My other car (Maxima) in auto form squeaks out a miserable 7 something second 0-60, with the manual it drops down to 5.9 seconds, but I thought most autos from 10+ years ago were pretty poor performance wise explaining the big difference.

The 6r80 is way better than past transmissions. Usually the auto is quicker and more reliable when it comes to shifts. Though two identical mustangs, the manual could slowly walk it. The drivetrain loss is still a little more than a manual. Better than what it use to be though. Also there is a weight difference. The 6r80 dry probably weights 100lbs more than the 82. Add 12 quarts of fluid, extra wiring, converter and flex plate, extra lines that run to the radiator and now it weights a lot more than the 82 manual trans even with its flywheel and clutch setup.

The 4.4 that I got, I feel I wasn't super aggressive due to the tires would spin. But you still have to find that balance at launching so it's aggressive but not too much.

Pa and temp will play a factor.
