need... more... traction... Frustrated with the cold weather and work, I decided I'm gonna take the seven out today, and for the first time, see what she can do from 0-60 in an unofficial test.
So I drove around until I found a spot on the highway, pulled over and let traffic pass, turned on data acquisition and took off when there was an opening.
I started the run directly from the shoulder, in 2nd gear. Tires had 5 minutes of normal driving on them, at 40 degree weather.
0-60 was pretty disappointing at 3.8 seconds
My data capture is below... Note % throttle
looking at the data, it confirms the way the car feels... if you go down the speed column, the change in speed every .2 seconds gets better as I pick up speed (except at 8 MPH, where it started to spin and I had to back off). It feels like it pulls just as hard from 60-100 as it does from 20-60.
Now this isn't an accurate test, b/c the wheels could be spinning at 60, but I looked at the data after I lifted off, and speed didn't drop.

tires I agree with above posts. I took my camaro out for a run last night and my 315's didnt have a prayer on the 1 to 2 shift, lol. 3.8 is pretty good considering the situation with the tires.
