Test Driver Ratings & Comments

Acceleration commentsReally stumbles off the line due to major intervention from traction control. Disengagement still leaves safety net. It'll allow about 2 seconds of wheelspin, then puts an end to it. Best run made in Manual mode (which shifts automatically at redline), with virtually no wheelspin. Ultra-smooth upshifts and a somewhat mellow engine note. Quicker than a Camaro SS to 60 mph!!
Braking ratingVery Good
Braking commentsMedium-to-firm pedal effort with virtually no hum or vibration from ABS. Car stays very level -- no dive, especially in Sport mode. Very good fade resistance.
Handling ratingGood
Handling commentsSkid pad: Very well balanced on the skid pad with only minor throttle adjustments needed to alter course when the stability control is disengaged. Once stability control active, the throttle closes a little earlier but not enough to change results. Slalom: Very frustrating car because it understeers past a cone, and then when you try to catch up by dialing in more steering, the rear lets go. Classic pushy-loose handling syndrome. With this car, it's generally a good idea that the stability control is never fully disengaged even when it's switched off.
