Acura makes few options available on the RL, but one, Collision Mitigation Braking System, uses this grille-mounted radar to detect imminent crashes. The system can cinch up seat belts, unlock doors, and hit the brakes.
We complained about the five-speed transmission in previous RLs, but Acura seems to have remapped the shift points on this new one for performance. Cruising at near 100 mpg, we found the fifth-gear powerband wide enough to keep engine speed down to 3,000 rpms.
Acura's navigation system has some nice features, and was the first to incorporate traffic reporting, but it is still DVD-based, making its performance and map storage capacity inferior to hard drive-based units.
