This clip of five-time Le Mans-winning Derek Bell piloting a Porsche Group-C 956 around the Nurburgring Nordschleife is of undetermined origin and vintage, but its definitely worth a spin round ones desktop if only to catch a 6:41 lap of the worlds most difficult circuit. Better still, the entire clip is calmly and informatively narrated by Bell himself (presumably done after the fact), so if youre planning a trip to the Ring (or just want to improve your Gran Turismo III scores), consider this a free in-car clinic.
