Test Driver Ratings & Comments

Acceleration commentsWhile it's not what I'd call torque steer per se, this car has enough power to produce pronounced nibble, wheelspin and general "squirreliness" with anything more than 3/4 throttle. That said, the traction control system can be caught completely on its heels and can only chop the throttle in reaction to the explosive boost only to release its grip right as the turbo is making crazy boost again, at which point it chops throttle, and so on.
Braking commentsPerhaps the most "OEM-feeling" part of the SEMA concept car. There's little idle stroke and intuitive progression that tends to feel more like a pressure- (rather than travel) regulated setup. I like it.
Handling commentsJarring, too stiff, needs attention in a big way. Sure the car looks right sitting lower than stock, but the springs feel too stiff, and the rebound too harsh. It needs to breathe better before it can handle better. I suspect it'd make decent numbers at our test facility with the one exception of the dip/hop at cone No. 3 on our slalom course. Also, detected some tire rub from the front.
