So if I understand correctly:

Traction control works by applying brakes to the wheel that is about to spin, thus reducing performance, while the PSD or LSD does the same job without using brakes?

Funny how many modern cars are now just switching to electronically controlled differentials when Porsche has been doing it for more than 20 years.

Also, this is an unfair demonstration, it's actually more useful for sharp curves at high speeds, than dirt.

The PSD diff was quite revolutionary, in fact, the 928 had more in common technologically with the amazing 959. The PSD in the GTS (MY 90 and up) was actually 959 derived.

It's crazy how the Germans had that in their car a long time ago.

This is a very informative video. What is really cool is the various comments attached to it. Besides being informative, they are about as funny as it gets, making me laugh out loud, if you will? -- zioo
