Test Driver Ratings & Comments

Acceleration commentsThis 4.8 is a nice engine, but it's not enough of a performance gain over the 3.0 turbo. Best launch from 3,000 rpm with quick clutch engagement and minimal wheelspin. Excellent shift action.
Braking ratingVery Good
Braking commentsWow, these brakes feel great but with such erratic stopping distances, it's hard to feel good about their performance.
Handling ratingVery Good
Handling commentsActive anti-roll bars work well on skid pad increasing roll stiffness and improving grip and control. In the slalom, the active anti-roll bars are disheartening in fast transitions on this surface. It feels like the chassis is always one step behind, trying to correct for my last input. Not ideal here.
