I used all my free time to work on this video in the last three months, I hope you'll enjoy it. :)
First to reach 11% WINS the Drag Race! This is a improvised Drag Race, I do it on the SPRINT number 29 from the Quick Race menu. I use my video editing software to skip frame by frame, that's how I see which one reach that 11% first.
Even if sometimes they might look equal in the video, most of the time, they are not, you should be able to notice it with the video speed set on 0.25x.
I did my best to follow the same route with every car.
The results are very accurate, in about 20 minutes of attempts I'll get the final result or a very close one, like +0.01s, at least two times. I tried to use different routes, it will not affect the final result by more than +0.05 seconds.

Gear change is set on "Automatic". Latest Body Kit installed for all the cars that are not CUSTOM.

Tuner Class most responsive handling and greatest amount of grip at the expense of top speed.
Exotic Class highest performing vehicles but are the most difficult to master.
Muscle Class fastest accelerating vehicles at the expense of top speed and handling.
