Test Driver Ratings & Comments

Acceleration commentsRequires higher launch rpm than base Corvette due to super-wide rear tires. Still, finding the right launch isn't impossible and it's fairly easy to pedal it to find traction, and a happy medium is fairly intuitive. There's still something satisfying about slamming a Corvette that sounds like this one does through the gears. We tried the built-in electronic launch control that was dead consistent, but ultimately slower (about 0.3) than our own organic traction control.
Braking ratingExcellent
Braking commentsConsistent, but not inspiring, pedal feel. Some awkwardness at full ABS -- a bit wooden, actually. Obviously powerful brakes.
Handling ratingVery Good
Handling commentsSkid pad: Massive grip, but not intuitive balance. Dumping the throttle does produce the desired effect; however, it's not as naturally adept at doing so as other sports cars that cost as much as this one does. We found an ever so slight advantage (0.01g) to running the skid pad in Competition mode. Slalom: Again, unnatural steering feel in quick transitions. Not completely numb, but also not talkative. Doesn't make me want to attack the slalom like other cars do.
