Acura Super Handling All-Wheel Drive

Seen on: Acura TL SH-AWD, Acura MDX

How it works: Acura's full-time all-wheel-drive system uses an electromagnetic clutch to vary the torque split, sending up to 70 percent of available power to either the front or real axle. However, the SH-AWD system's torque vectoring on its rear axle is what transformed the large TL and the downright massive MDX into handling gems. Up to 100 percent of available rear axle power can be sent to either rear wheel via a second electromagnetic clutch-actuated rear differential. During cornering, the TL can send about 160 pound-feet of torque (estimated with drivetrain loss) to the outside rear wheel to help rotate the vehicle around its center, reducing understeer and improving handling significantly.
