S-AWC (Super All Wheel Control) is the brand name of an advanced full-time four-wheel drive system developed by Mitsubishi Motors. The technology, specifically developed for the new 2007 Lancer Evolution, is an advanced version of Mitsubishi's AWC system. Mitsubishi first exhibited S-AWC integration control technology in the Concept-X model at the 39th Tokyo Motor Show in 2005. According to Mitsubishi, "the ultimate embodiment of the company's AWC philosophy is the S-AWC system, a 4WD-based integrated vehicle dynamics control system".
It integrates management of its Active Center Differential (ACD), Active Yaw Control (AYC), Active Stability Control (ASC), and Sports ABS components, while adding Braking force control to Mitsubishi Motors' own AYC system, allowing regulation of torque and braking force at each Wheel. S-AWC employs Yaw rate feedback control, a direct yaw moment control technology that affects left-right torque vectoring (this technology forms the core of S-AWC system) and controls cornering maneuvers as desired during acceleration, steady state driving, and deceleration. Mitsubishi claims the result is elevated drive power, cornering performance, and vehicle stability regardless of driving conditions.
