Test Driver Ratings & Comments

Acceleration commentsPDK transmission makes launching effectively relatively mindless -- even compared to other cars with launch control. It also doesn't feel abusive -- as if it was designed for this, which it was.
Braking ratingExcellent
Braking commentsUneventful. Solid pedal stop after stop after stop. Excellent confidence and no softening of pedal.
Handling ratingVery Good
Handling commentsGobs of grip raise the 911's limits far beyond what most Cabriolet drivers will ever use. Balance leans toward understeer and the 911 refuses to step out even when coaxed. Amazing.
