Fuchwheeler:

any new development for the Porsche 991 ?

You can figure out what Porsche is doing for their upcoming models just by reading their recent patents Smiley

A hybrid turbo system where an extra turbine is used to charge the battery at high RPMs and reduce turbo lag at low RPMs.

Steel coil springs with dynamically adjustable spring rates (much like an air suspension).

Dynamic camber adjustment in conjunction with PDCC.

A convertible with a folding hard top. 

A hybrid drive train that works with PDK.

A panoramic roof for the Panamera.

For the roof, if you look carefully at the video posted by Boxter GTS, at 0:33 you can clearly see that a similar system is going into the new 911.  As for the other ones, only Porsche knows. Smiley
