The rear is impressive as well. The active aero air- curtains to help rezolve the wake off the rear 145/70r17's w/active aero wheel covers.

Control?
Any theories on how they have mechanized the louvers in the wheel?

Some sort of a power generation mechanism harnessing centrifugal force, if it's electrical.
My mind went towards a purely mechanical mechanism. Simply using a bi-metal spring,(like a clutch fan or thermostatic stovepipe control mechanism used on carburetors) calibrate it on a safe operating temperature of the brake hardware. As demand for cooling increases the bi-metal gets hotter and opens further.

Another note from reading the article.
All their active Aero activates at 70 kph.(43mph) implying a simple lack of advantage below
