Test Driver Ratings & Comments

Acceleration commentsRev-limited to 3,800 with ESC on; no limit (below redline) when it's off. Seems relatively indifferent to launch technique -- only a few hundredths of a second separate clutch dump from careful modulation by 60 mph. Shifter is less likable when rushed in this environment. Engine is done at 6,500.
Braking commentsConfident pedal every stop, but fade (+6 feet) present. Not the best braking in the segment.
Handling commentsSkid pad: Heavy steering with quite good communication at the limit. More body roll than expected makes sensing grip limits more difficult. Still, good balance. Adjustable, but slower to respond than I'd prefer. Slalom: Ample body roll makes quick transitions feel awkward. Even so, limits are reasonably well defined. Excellent ESC produces quickest slalom time by 0.01 second.
