The Koenigsegg One:1 has the world's first top mounted, active rear wing ever placed as a standard feature on a production car. How does it work? Christian Von Koenigsegg is glad you asked.

This week on /INSIDE KOENIGSEGG 2, Christian talks about the One:1's active aero bits, in particular that rear wing: Why it's top-mounted, the difference between this system and that of a Le Mans car, its weight benefits and, of course, what effect it has on the car at speeds of up to 280 mph.

It's a mini active-aero lesson, given by the world's most aerodynamic supercar builder.
