Red Bull got a couple drifters and sent them up all 99 corners of Tianmenshan Mountain in China. The road includes a giant hole in the rock called "The Doors to Heaven." Neato!
Apparently it was a drift battle between James Tang, from Hong Kong, and Federico Sceriffo, from Italy, but you don't really get that until the end when they're holding up trophies for some reason.
There's a second video to be released some time in the future.
