1994 Porsche 911 Carrera 4

For the new 993 platform, Porsche heavily revised their four-wheel drive system to include a viscous coupling system that distributed power to the front and rear wheels. This made the model much smoother than the C4 it replaced.

Along with the new viscous coupler from Viscodrive, Porsche fitted a rear limited-slip differential and and automatic brake differential which applied braking force to a slipping rear wheel.

The system was vastly better than the 964’s computer controlled unit in that it added only 110 pounds to the weight of the car and had 50% less friction loss.

Outward, the Carrera 4 was distinguished by it’s titanium-finished brake calipers, clear front turn signals and rear rear turn signals.
