The German Grand Prix circuit that was used for a Formula 1 race for the last time in 1976, when Niki Lauda was almost killed, was the Nürburgring Nordschleife. Considered one of the most challenging and dangerous tracks in motorsport history, the 22.8-kilometer circuit featured tight corners, elevation changes, and long straights, with little room for error. Lauda suffered severe burns in a fiery crash during the race, which led to significant safety improvements in Formula 1, including mandatory fire-resistant suits and improved barriers and fences around the tracks. The Nürburgring continued to host other motorsport events and was eventually revamped into the modern Grand Prix circuit that is still used today.
