Look at the vanes!
Like an earlier poster mentioned, it looks like the engine cover vanes are made of separate parts, all being able to move... would be interesting!


I bet the front radiator ducts also have aero slats wich can close as VW owns that patent since 1971.

Porsche Active Aero Package is coming! and it will not be free! haha Smiley

We will find out if it actually does improve high speed stability or if its just another money $$$$ making option.

Of course you will be able to get a 991 without it, but your Porsche will make you feel guilty everytime you look at your engine lid slats knowing that they  could have been moveable. Smiley

You can be sure Porsche will also offer Porsche Active Aero Package Plus and Porsche Active Aero Package 2. Smiley
