Test Driver Ratings & Comments

Acceleration commentsAs per usual, getting the right launch means finding the optimal spin-to-bog tipping point. Very noticeable VTEC cam phasing. Shifter is brilliant, quick and well defined. Too bad about the 2nd-gear ratio hitting the rev limiter just shy of 60 mph and necessitating a shift to 3rd. Love the sound of this engine!
Braking ratingGood
Braking commentsUltra-consistent distances and fade-free stops, though we did smell brakes after both decel and accel runs. Adequate pedal feel and easy to modulate in everyday driving, too.
Handling ratingExcellent
Handling commentsStability control merely closes throttle (no brake application), but it still grips rather well. With stability off, the Si responds only slightly to throttle input/output. Holds a line very well with mild understeer. Overall, very good balance. Steering feels spring-loaded, offers some feel but not much. In the slalom, stability is pretty crude and abrupt with brake application. Shutting it off releases the chassis' full potential, which is astonishly good. Lightning reflexes from steering and weight transfer is immediate. This car does exactly what it is told to do. Very little roll and limited-slip differential makes the exit easy-peasy at wide-open throttle.
