Test Driver Ratings & Comments

Acceleration commentsWith the open differential, there's nothing to be gained by turning the traction control off. It just does a one-legger and falls behind. Rear end is quite loud, too, like every taxi cab I've ever been in. Tall gearing doesn't help the times much; it crossed the quarter-mile in 2nd gear.
Braking commentsLike pushing your foot into a bucket of tofu, but reasonably fade-resistant tofu. Lots of dive, but no side-to-side wandering.
Handling commentsSkid pad: Big car, big lean, squealing tires, understeer and a bench seat make it quite the handful on the skid pad. Checked the door lock twice to make sure I wasn't going to fall out onto the pavement. Slalom: It starts out feeling like a traditional rear-wheel-drive car but quickly devolves into something more akin to a carnival ride. Best run was achieved by going slow in and then timing the inevitable slide out of the last gate.
