Test Driver Ratings & Comments

Acceleration commentsThe traction control system works very well to quell (invisibly) the RDX's runaway wheelspin with VDC off. It took several attempts to beat the system, so it'd be easier to leave it on. Some torque-induced nibble (but not torque steer). Power wanes only slightly near redline. Upshifts could be smoother, but there's no denying the RDX is quick.
Braking ratingAcceptable
Braking commentsGravelly-sounding tires seemed to hunt for traction and stops were not arrow-straight - some veered right, some wiggled and some stumbled (nearly locked up) from 25-0 mph. Still, inconsistent as it was, stopping distance and fade were acceptable.
Handling ratingGood
Handling commentsSkid pad: Will easily lift and spin inside front tire with VDC off and that's the limiting factor. With VDC on, the throttle closes before this happens and there you are. Steering feel is rather good with appropriate info and effort. Slalom: Pretty darned entertaining with stiff springs and the quick transitions they provide. Steering is light and precise, but as in the skid pad, the limit is determined by the spinning, unweighted front tire. Good rotation without threatening to spin. Speed with VDC on is remarkably close to that achieved with VDC off, so calibration is quite good.
