Perfect traction was Porsche’s goal when they designed the 959. The PSK 4-wheel drive system was the technological highlight of the 959. PSK, which did add weight to the car, could vary the ratio of torque to the front & rear wheels. The default setting for the system was 40% front and 60% rear. Under acceleration the PSK adjusts to ratio to 80% torque to the rear wheels. During slippery conditions the ratio was 50 : 50.
The main difference between the Sport and normal version of the 959 was the weight. Porsche lightened the 959 by 100 kilos. To do this they removed the adjustable ride height system, adjustable dampening system, rear seats, power windows, air-conditioning, central lock, passenger side mirror.
