The 'Ring Video
The Nuerburgring in Germany is probably the most famous race track in the world, particularily the old Nordschleife. BMW has used the old track as a test bed for decades now, going so far as having a permanent test facility bordering the track. Following the jump is a video produced in part by BMW (and played originally on TiVo sets) that explains some of the mythos of the track known by old time racers as the "green hell" for its treacherous corners and hills. Enjoy.
