Test Driver Ratings & Comments

Acceleration commentsBest launch from 4,750 with clutch drop. Won't tolerate any clutch slip from this rpm. Perfect shifter -- direct, precise, able to tolerate speed.
Braking commentsSolid, consistent pedal. Stops straight with little lateral wander and almost no pitch.
Handling commentsSkid pad: Rewards small throttle and steering adjustments on limit with ESC off. Small lift = small rotation. Doesn't want to oversteer. ESC on: Retains excellent manners with lower limits. Still very capable, though. Slalom: Remarkably easy car to slalom. Communicates its intentions clearly as limits approach. ESC on: Intervention is minimal and helpful. Doesn't feel like it punishes. ESC off: Superb balance that's completely accessible. Even pushing hard, it remains fully composed. Comfortable oversteer at exit, which is rare in midengine cars. No issues with electric steering when it comes to driving hard. Feels a little synthetic (like 991 911) if I focus on it during normal driving, but if I drive hard it doesn't matter.
