"Unlike Volvos and Saabs, which use front-drive layouts that are least
able to manage extra turbo oomph, the WRX comes only with a seamless
full-time four-wheel-drive system. On manual-transmission models, the
torque split between the two axles is 50/50, and a viscous limited-slip
unit on the center differential can redistribute torque if one axle slips.
On cars with automatic transmissions, the torque split is 45/55, and an
electronically controlled clutch pack acts on a planetary center diff to
redistribute engine torque."
