On real-world roads, the Acura MDX’s active suspension was impressive, offering a clear difference between the default Sport setting and the available Comfort setting. Steering effort levels seemed a tad bit stiff at lower speeds and it lightened up significantly when cresting a hill, but at higher speeds was perfect. The brakes were responsive, almost touchy, and quite effective at arresting velocity. The wide tires gripped well in the dry and the wet, but tugged and hunted a bit on rumpled pavement.
