| SYMMETRICAL ALL-WHEEL DRIVE |
| |
WRX and
wrx premium |
WRX STI |
|
|
|
|
| CONTINUOUS ALL-WHEEL DRIVE |
WRX models utilize a viscous-type locking center differential with torque distribution normally configured at a 50/50-split front-to-rear. If wheel speed differs between front and rear axles, the system helps distribute power to the wheels with the most traction. |
| DRIVER CONTROLLED CENTER DIFFERENTIAL (DCCD) ALL-WHEEL DRIVE |
Exclusive to the WRX STI, Driver Controlled Center Differential (DCCD) All-Wheel Drive uses an electronically managed multi-plate transfer clutch and a mechanical limited-slip differential in conjunction with a planetary-gear-type center differential to control power distribution between the front and rear wheels. Featuring manual and three automatic modes, DCCD splits power 41% front and 59% rear. Sensors monitor parameters such as wheel slippage, steering angle, throttle position and braking to help determine torque distribution and direct it to the wheels with optimum traction. DCCD also features a limited-slip helical front and Torsen rear differential. |
| Stability and Traction |
| |
WRX and
wrx premium |
WRX STI |
|
|
|
|
| Vehicle Dynamics Control (VDC) |
VDC electronic stability control utilizes sensors which constantly monitor wheel speed, steering angle, brake pressure, vehicle yaw rate and
lateral g-forces. If VDC detects a difference between the driver’s intended path and the one the vehicle is actually taking, VDC applies braking
power and/or reduces engine torque to help correct vehicle path. Exclusive to the WRX STI, VDC features standard, Off and performance -oriented Traction modes. |
| Traction Control System (TCS) |
VDC also incorporates an all-wheel, all-speed traction control system which senses a loss of traction and applies braking force to the slipping
wheel or wheels as necessary to maintain vehicle motion. |
