The Acura MDX hits 2017 with a new standard 9-speed automatic transmission with push-button gear selection. Acura claims the ZF unit is 66 pounds lighter than the 6-speed it replaces. Acura has revised the Super Handling All-Wheel Drive system (SH-AWD) as well, with a twin-clutch rear differential. A multi-view rear camera is new, as is AcuraWatch Plus, a suite of active safety features that includes collision mitigation braking, road departure mitigation, lane keeping assist, adaptive cruise control, forward collision warning, and lane departure warning. While AcuraWatch was previously available as part of the Advance Package, the new group is available on all MDX trims.
