Auto races in germany
Sport Auto is a German automobile magazine, established in 1969, published monthly by Motor Presse Stuttgart, based in Stuttgart. The magazine publishes its "Supertest" of cars, featuring the laptime (usually driven by editor-in-chief Horst von Saurma) at the Nordschleife. The magazine also runs a challenge for the fastest lap time driven with a car that is road legal (TÜV) and registered in Germany. The road legality rule also applies for the tires.
