FRS should easily beat an Audi TT at an autocross event on a good concrete or asphalt surface given equal drivers. Autocross is about nimbleness and quickness in changing directions along with reading the course and knowing where to place the vehicle. An Audi TT is really at a serious disadvantage here. Width is a major thing in autocross...and the Audi TT is over 2.5" wider than the FR-S. Wider is not really better when it comes to threading a slolam, the key to the slolam (and chicane) is moving as little as possible. So the wider the car, the more you have to displace it from side to side. The straighter you can keep the car, the faster you can push.
Then again the driver does make a difference; like a good driver in a stock height 2.4L 4-cylinder Tacoma Extended cab beating about half the drivers at a 150+ driver events including those with Corvettes, Miatas, WRX's, S2000's, and BMW 3 series....
Weeeeee....
