Mercedes Benz CLRFollowing the practice backflip on the Thursday before the race, the Mercedes Benz CLR folklore talks of a panicked phone call to Williams F1's Adrian Newey in order to cobble together a fix for the car.  The solution, which amounted to a twin set of diveplanes and a wheel well leading edge gurney lip, supposedly increased front downforce by a whopping 25%.  But considering the power of diveplanes, 25% is a massive amount, and simply speaks to a complete and fundamental lack of downforce exerted by the CLR.  
Certainly not the best image, but we take them how ever we can.  Note that the nose diffuser is relatively conventional, not as agressive as the raised nose Toyota GT-One.  The diffuser appears to be planar, transistioning from the flat splitter to the flat diffuser kick across an edge.
