Test Driver Ratings & Comments

Acceleration commentsNot enough torque to give the traction control a workout, just a little bark. Trans shifted a little shy of redline. Found some gains by shifting manually at 7,500 rpm (500 over redline). Could use another gear to keep the engine on the boil.
Braking ratingPoor
Braking commentsWhile the distances from 60 mph were erratic, ranging from 134, 133, 138, 135, 134, we witnessed dramatic fading only after three successive quarter-mile runs. Still, a best stop on par with a moderately sized crossover is a poor performance for a sport-luxury sedan. Summer tires would likely help.
Handling ratingAverage
Handling commentsSlalom: Lacking speed here compared to manual TSX, likely due to the automatic's wide gear spacing, which hurts acceleration at end of slalom. Skid pad: Very little feedback through steering makes limits hard to sense.
