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.
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
Differential is ok. But if you realise that you are too fast to pass the bend when you are just at the beginning of a bend, then if you brake, how will be the reaction of your car? Could it pass the bend or will it have the danger of an overthrown. I mean the brakes must also have a similar differentiation.
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?
The PSD lets you put all the power down, instead of limiting your throttle. If you put all your power down on ice, you're still not going to get traction with PSD. With traction control, the ECU will cut your throttle to reduce wheel spin. ESP (electronic stability program) will then brake individual wheels if you're still getting out of control.
Yah, it does seem like the active differential which was used in the 959. I guess since Porsche were the only once using it in 1989 when 959 was phased out they may have publicized it as PSD in 928
I agree. Just slap on a mechanical LSD, and walk away. Porsches are way too refined for my taste. Who wants a computer making driving decisions for you?
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.

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

So if I understand correctly:

its also short for limited slip differential

wouldnt an LSD be easier with less potential failure?
