In 1988 Audi took part for a year in the American TransAm race series. The engine installed in the Audi 200 quattro was the turbocharged five-cylinder unit that previously powered the world rally championship cars, in the meantime developing 375 kW (510 bhp), enough to secure the title for the American driver Hurley Haywood. Audi in fact took the chequered flag eight times, a total which secured the manufacturers’ title as well.
