"Thankfully, the 2015 STI comes with two more mechanical differentials as well; a helical-type limited-slip up front and a Torsen in the rear."
a o torque vectoring napisali tak:
"For the first time on an STI, active torque vectoring will be included, but sadly relies on brake applications to the inside front wheel to improve cornering ability."

"The 2015 WRX STI is exclusively equipped with the Multi-Mode Driver Controlled Center Differential (DCCD) version of Subaru Symmetrical All-Wheel Drive. This sophisticated system uses planetary-type center differential gears with a nominal 41:59 torque split. A mechanical limited-slip type center differential augments an electronically controlled center differential to enhance torque transfer performance.
Sensor inputs that include steering angle, throttle position, RPM, lateral-g, yaw, brake, ABS and wheel speed govern torque transfer response. A helical-type limited-slip front differential and a TORSEN® torque-sensing limited-slip rear differential optimize side-to-side torque distribution."
Active Torque Vectoring, an enhancement of the M"ulti-Mode Vehicle Dynamics Control (VDC) stability and traction control system, can apply brake pressure to the inside front wheel to facilitate more neutral cornering. The VDC system offers yet more driver choices, with three settings: “VDC Normal,” “Traction” and “Off.” Each provides respectively lesser degrees of system engagement, allowing the driver to tailor response for the driving situation. Active Torque Vectoring remains engaged for “Normal” and “Traction” modes."

Driver Controlled Center Differential (DCCD) All-Wheel DriveExclusive to WRX STI, 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.
