The Nürburgring has been hallowed racing ground and home to professional racing events, once including the German Grand Prix, since 1927. Fearless, white-knuckled drivers of lore, like Jackie Stewart, Sir Stirling Moss and Phil Hill called the circuit "Green Hell" for its torturous curves, elevation changes and its propensity in spots to send cars airborne. These days, the track's accessibility, both virtually and in real life has made the Nürburgring Nordschleife an institution for car nuts. It's a must-master for Grand Turismo and Project Gotham gamers, but anyone can take a lap in real life for €21 ($32.60) or €70 ($108.66) for four laps. 'Ring fans from around the world refresh the track's webcam hundreds of thousands of times daily, scanning for the top-secret test prototypes carmakers routinely bring for performance testing. Those photos also feed the websites hungry for hints at what's next from carmakers.
