The wing is flat at speeds over 220 kph to create less drag, which means higher top speed. Under 220 kph it's tilted to provide downforce. This way you get both cornering capability and high top speed.

It has nothing to do with braking (it does not function as an air brake, like in MP4-12C or Veyron).
