In 1986, the first six quattro years came to an end. Mouton, Mikkola, Stig Blomqvist and Walter Röhrl had won 23 world championship rallies and taken four titles home to Ingolstadt. With a near-standard Group-A model, Audi even won the gruelling Safari Rally in the transitional year of 1987. This era was a model example for the realisation of real technical advances through motorsport: quattro as a winning idea. After Audi had turned rallying upside down and conquered Pikes Peak (USA) three times in a row in record time with the Sport quattro, the brand then made quattro drive suitable for circuit racing: first with the Audi 200 quattro in 1988 in the Trans-Am Series and the Audi 90 quattro IMSA-GTO in the USA in 1989, then in 1990 and 1991 with two championship titles for the Audi V8 quattro in the German Touring Car Championship (DTM) – and also with the A4 quattro in the Super Touring Cars competition for production-based cars. In 1996, the Audi A4 quattro won the title in seven countries. Between 2012 and 2016, four-wheel drive returned to the racetrack as e-tron quattro in the LMP1 Audi R18 race car.
