S-AWC (Super All Wheel Control) is the name of a driving dynamics control system from Mitsubishi that has been installed in the car brand's four-wheel drive vehicles since 2007. The system controls how much torque is sent to each wheel, improving the vehicle's dynamics, handling, safety and off-road capability.
Like this the S-AWC system works
The all-wheel drive on vehicles with the S-AWC system can be permanent or selectable. An electronically controlled multi-plate clutch or center differential that splits torque symmetrically is used to distribute torque to the axles. In the hybrid versions there is no mechanical coupling between the axles. The rear axle is driven by an electric motor.
The S-AWC system optimizes the operation of the following systems:
AYC (Active Yaw Control): It controls the wheel differentials and power steering. The system distributes torque to all four wheels depending on road conditions.
- ASC (Active Stability Control): It helps maintain the desired direction of travel by slowing a slipping axle and reducing engine torque .
- Sports ABS: This system improves braking when cornering and prevents skidding.
Technical properties of the S-AWC-Systems
Type of drive | Torque distribution | Modes | Mitsubishi models equipped with this type of drive | |
between the axles | between the wheels | |||
Automatic four-wheel drive | The multi-plate clutch engages in the rear axle when it detects that the front axle is slipping. | The AYC controls the power steering, active front differential, power steering, active front differential and brakes. | Eco: to save fuel. Snow: on slippery surfaces. Normal: for dry roads. Lock: for off-road surfaces. | Outlander |
Automatic four-wheel drive | The twin-motor four-wheel drive controls the two electric motors, each their own drive its own axle. | AYC uses braking mechanisms to slow spinning wheels. | Normal: for driving on good surfaces. 4WD Lock: for off-road conditions. | Outlander PHEV |
Permanent all-wheel drive | The center differential distributes the engine torque in a 50:50 ratio. | The AYC controls the brakes and the active differential. | Asphalt: for dry surfaces. Gravel: for wet and dusty surfaces. Snow: on slippery surfaces. | Lancer Evolution |
