Test Driver Ratings & Comments

Acceleration commentsRan a 4.66 with all systems on; only improved to a 4.61 with stability control "off." Went quickest by going straight from brake to throttle, not power braking. With all-wheel drive, no traction issues. Transmission shifts relatively quickly, always utterly smooth. No heat soak. Ran car in softer suspension setting. Manual shifting via steering wheel paddles; does not hold gears to limiter.
Braking commentsVery solid pedal feel and dead straight and confidence-inspiring stops. No fade, good, short stopping distances considering the car weighs nearly 4,700 pounds. Credit to the big brakes and grippy tires. Ran car in Sport suspension setting for braking.
Handling comments"Skid pad: Chassis was very willing to alter its attitude with drop-throttle, surprising for such a big and heavy coupe. No problem putting the power down with AWD. But it was easy to overshoot the arc when getting back on the gas because the throttle is so sensitive. ESC hardly cut in here at all, whether ""On"" or ""Off.""
