Acceleration during cornering
Torque to the rear wheels is continuously varied to supply up to 100% to the outside wheel and 0% to the inside wheel. This creates an inward yaw moment, significantly improving vehicle handling.

World’s first direct electromagnetic clutch
An electromagnetic coil (electromagnet) attracts a magnetic body which, in turn, presses on the multi-plate clutch to facilitate torque transmission. A compact clutch unit, equipped with a planetary gear step-up mechanism to increase torque, permits transmission of substantial amounts of torque. A built-in search coil monitors the gap between the electromagnetic coil and the magnetic body. Current flow in the electromagnetic clutch is then adjusted to achieve highly precise torque regulation.

Sensors, ECU
The input of steering angle, lateral g, yaw rate, wheel speed and other sensors monitor driver input, vehicle demeanor, and driving conditions such that the SH-AWD ECU can calculate ideal torque distribution.
