Test Driver Ratings & Comments

Acceleration commentsThe TSX is hard to launch effectively due to lots of weight transfer and low-grip rubber. The engine performs well, but isn't on par for this segment.
Braking ratingPoor
Braking commentsThis is not acceptable braking performance for a car in this class at this price point, and the TSX's 127-foot 60-mph-to-0 stopping distance (achieved on the first run) doesn't tell the whole story. There was considerable fade by the second braking run, and by the third run, the brakes were smoking. We also noticed massive fade when slowing after acceleration runs, which indicates this brake system's lack of thermal capacity. We suspect the brakes on this TSX test car had never been heat-cycled (given that the car had only 850 miles on its odometer), but even so, we expected much better performance in this test.
Handling ratingAverage
Handling commentsSlalom: Light damping doesn't offer the control needed to blast through the slalom's surface irregularities. There's lots of body roll and no information through the steering. Skid pad: The TSX has decent balance and lift-throttle response before the front tires overheat. The lack of steering feel at the limit hurts confidence.
