We're not sure exactly how real this footage is (being as we live in such a cynical CGI age), but if it is real, then this spot of drifting around the edge of 1000ft-high helipad is a darned impressive piece of driving.
It's all intended to demonstrate the BMW 1-series M Coupe's credentials as a pukka M car and, presumably, the large cojones of the stunt driver. It's been shot on the US Bank Tower in LA which is, apparently, the tallest building in California.
Quite a feat, really, but for spectacular precision driving we must say that the prevailing PH office opinion is that 'MPowered Performance Part 1' (the bottom-most video) is somewhat better, though perhaps a little less death-defying...
