Active rear wing
Here's the Top Gear story on it

Here's the company web page.

I worked on one that was brake controlled and he has added steering inputs.
I think I've found the next big thing I can use my iPhone for. It has accelerometers!

Crap, I didn't even notice that on Sias' car on Sunday (at least it looks like his SM M3).
I saw a similar thing on UTA's '04 FSAE car, theirs was all done mechanically based on the suspension movement, so it wasn't perfect (ie it provided downforce under braking and low drag under acceleration but this leads the loaded side to get more downforce during cornering when the unloaded side should get it).

I hate it when people don't know history. The very first wings on race cars worked like this, but they didn't need any fancy computerized servos.
Chapparal was doing this back on their cars in the 60s. They had the wing set up spring-loaded. When they were on the straights, the driver placed his left foot on a lever that held the wing in a no-lift position. When he went to brake for a corner, he used his left foot for braking and so the wing snapped out into high lift/drag. Once back on the straight after the corner, he just covered the wing pedal again, and the wing came back into the low drag position. (The cars were automatics, so no clutch was involved.) It worked so well it got banned.
The also had the wings directly connected to the rear suspension instead of forcing the load to go through the springs. Likewise banned. Expect to see that soon as another great "innovation"....
