Electronic LSD is fully variable in lock while mechanical is 22%/27% in lock.

Just one thing-Ferrari is a long time e-diff user.


Is it a proper electronically controlled limited-slip differential or a brake-applied system as on cheaper cars?

 Hah, I was going to ask the same question.  I understand that the Jaguar XKR-S has electronically controlled mechanical diff (if that made sense!) so it is able to vary the lock from 0 to 100 percent.  That would be pretty impressive if we have that in the 991!  On the other hand, I have the brake-applied system on our new city car the Polo GTI, and it doesn't act like a real LSD at all.

Strange question since it is after all a 911.
 

Electronically controlled LSD of course! I have extended file about it in German. It is so called networked system where PDK, PTV and all other systems work together. Lock is fully variable depending on PDK programm, road speed etc. Sharpest one is with PSM off.
