Test Driver Ratings & Comments
Acceleration commentsAbsolutely hates pedal overlap, but there's plenty of power at launch for wheelspin. Traction control is very effective, and I was not able to improve on its ability with it shut off. There's no difference between Normal and Sport at wide-open throttle, but manual shift works in Sport. Bright engine with power all the way to redline upshifts.
Braking commentsConsistent stopping distances from 60 mph; however, noticeable brake pad odor after four stops and softening pedal feedback.
Handling commentsSlalom: Good crisp steering response; however, the body roll delays a change in direction. Stability system is rather lenient and only intervenes when steering doesn't match direction of travel. Confident and competent, but not outstanding. Skid pad: Very gentle, almost imperceptible throttle closure as the car approaches the limit of the front tires' ability to grip. Good steering weight and decent feedback.
