Acceleration comments Turning off stability/traction control also removes launch rev limiter. However, electronics still protect drivetrain once the clutch comes out through throttle manipulation and clutch damping. Very respectable numbers with stability control on or off. Incredibly responsive engine. Good shifter.
Braking comments Solid pedal has more mechanical feel than some competitors. Loud ABS. Consistent, fade-free stops.
Handling comments All handling tests with Drive Select in Dynamic mode. Somewhat erratic front grip (perhaps due to varying torque split?) makes driving around the skid pad more difficult and less predictable than some RWD competitors. With stability control on , however, it works awesomely on skid pad. Requires neutral throttle or acceleration with stability control off through slalom. Otherwise, it will go backward -- probably a useful trick on the track or back roads.
