Test Driver Ratings & Comments

Acceleration commentsAll runs in "Drive" because there are no other options. Fastest run was made with no brake torquing. Manual shifting not any faster. Transmission upshifts itself between 400 and 0 rpm before redline.
Braking ratingExcellent
Braking commentsSoft pedal. Long travel. Lots of suspension settling after car actually comes to a stop. Quiet ABS.
Handling ratingExcellent
Handling commentsSkid pad: Dynamic control invasive if the car begins to oversteer. And the system cannot be disabled. Flat cornering. In the slalom the active suspension is obvious and functional. Amazing precision considering the car's size and weight. Stability control reels in antics.
