| Test Driver Ratings & Comments |
|---|
| Acceleration comments | Launch control is fairly worthless on our low-grip test surface. Its 5,000-rpm base is too high and its closed-loop throttle manipulation (using front wheel speed) is both too slow and not effective enough. Basically, launch control resulted in a big burnout. I chose a 3,000-3,500 launch rpm and had the best luck with a little clutch slip rather than a dump. Shifter is awesome -- much better than before. Never missed a gear. |
| Braking comments | Solid pedal feel and good response. Consistent performance, but these (optional) P Zero Corsas are clearly less sticky than the optional Michelin Pilot Sport Cup rubber on the Z06 and ZR1. |
| Handling comments | "Skid pad: Heavy understeer attitude, but massive grip. More throttle equals more understeer. Won't respond to lift-throttle, which is probably good in a car with limits this high. Steering is direct and immediate. Ran all handling tests in "Street" damping, as "Race" was too stiff and made the car nervous. Feels like this level of damping is really only appropriate at high speed. |
