The Nürburgring Nordschleife, undoubtedly the most feared and revered racing circuit anywhere in the world. Its vast and ancient 12.9 mile length demands near constant resurfacing in one area or another, meaning changing levels of grip from one season to the next.
Its position in the Eiffel Mountains also makes it possible to embark on a dry lap on slick tyres before entering a sudden deluge at high speed. Not for nothing have Formula 1 drivers attempted to boycott the Nordschleife on more than one occasion, with only sports car racing still a regular feature today.
Jacky Ickx won the 1983 World Endurance Championship here in a Porsche 956, but it was teammate Stephen Bellof who would steal the limelight that year after lapping the circuit in an astonishing, and still unrivalled, 6.11.13 minutes.
