The locking diff on the 928 is way cool. The locking is pneumatically activated. Porsche calls it PSD. It uses speed, speed of each wheel, acceleration, direction of travel, accelerator, brakes, and steering wheel input, all to determine how much to lock the rear diff and or which tire to apply what percentage of the power to.
