I saw the original Ken Block Gymkhana video a few years ago, and he outdoes himself on this one. However, I think I still prefer Gymkhana 3 - Ultimate Playground, as it has much more of an "open road" type feel, and the audio (and sound-editing) is superb. You really get a feel for what a beast this car is, and there's more footage shot from the car. Knott to mention that the outrageous ending is pretty hard to top!

Shot just south of Paris, France in Linas at l'Autodrome de Linas --Montlhéry, this 1.58 mile oval track, built in 1924, features banks as steep as 51 degrees, which is more than double the standard incline of most NASCAR ovals. Chosen by Ken for this specific reason, the ramp-like banking proved to be a unique and exciting challenge. The driving physics for the stunts performed were totally unknown until Ken attempted the maneuvers during filming
Here's the link. I'm knott embedding it because there's no way to go full screen, and that would be a crime.
Again, go at least 720p, full screen, and crank up the volume!
