I recommend putting on a condom before watching this....

Holy shit I think I just got my iPad pregnant. :biggrin:

notice the rx7 reverse lights?

LOL... it probably would do 180 if it didn't have those. :biggrin:

I would think the wing moves upward (less angle of attack) to reduce drag and cut excessive downforce when you get to high speeds. Think of it as DRS from F1.

The F1 DRS opens up a gap. Not angle it up towards the sky.

maybe, but this angle looks like it would act as an airbrake.

It almost looks as if it is breaking from the force. It doesn't look like a controlled mechanical movement.

Found this info on the Dynamic Rear Wing on the Koneiggseeggeessgggggeeegg website:
http://www.koenigsegg.com/models/agera-r/

Dynamic rear wing
Hypercars of today generate massive amounts of downforce at low to medium speed and less down force at very high speed. This is so as to avoid overloading the tires and creating too much drag. Most hypercars therefore have heavy, hydraulically operated wings and flaps to cater for this need.

Koenigsegg however, following the “less is more” philosophy, has designed a dynamic system to that take care of these needs.

The most visual and obvious part of this system is the new dynamic rear wing. The wing changes its angle of attack, not with the help of hydraulics, but with the pressure of the wind. It is therefore dynamically controlled by the vehicle speed, or wind resistance, at any given moment in time and thus actually compensates for headwind or tailwind at the same given speed. This is an intelligent way of dealing with adaptive aerodynamics as the system becomes lighter, less complex and more intuitive compared to heavy and complex hydraulics systems. Koenigsegg had to work heavily with CFD in order to create the dynamically controlled adaptive aerodynamics of the Agera R.

An interesting additional feature of the adaptive wing is that the pylons for the wing also act as air extrusion channels. The air channels go from the engine bay to the back of the pylons, thereby creating an air passage. This causes a venturi effect from the air rushing past the pylon, evacuating hot engine bay gases, reducing pressure in the engine bay and increasing the flow of cooling air through the side radiators. This also means that the pressure under the car is reduced, giving more low drag down force.

The F1 DRS opens up a gap. Not angle it up towards the sky.

I mean functionally. Reduces downforce in order to reduce drag and as Hapa88 quoted, reduce the load on the suspension and tires.

The reason it angles up is the angle of the airflow down the back window is going down. A zero angle of attack wing would actually be pointing slightly up. The stock wings on our NSXs actually angle up very slightly and that's still a positive angle of attack because the air is going down.

I rather enjoyed that!
