1990: Stuck wins for Audi
Champion: Hans-Joachim Stuck
Ford withdrew from the championship in 1990. Instead, Audi joined the series as a newcomer, and the title went to Ingolstadt in the brand’s first year. Hans-Joachim “Strietzel” Stuck, the public’s darling, triumphed in the four-wheel-drive Audi V8 quattro. Audi prevailed against their strong rivals not only thanks to the four-wheel-drive advantage: The Audi’s V8 engine also had more power than the four-cylinder units.
