Walter Röhrl
First shown at Frankfurt in September 1979, the Ascona 400 was a homologation special sold only to make it eligible for rallying's Group 4 category. The Ascona 400s were built at General Motors' plant in Antwerp. The 1980 world champion Walter Röhrl took the rally car to victory and won the World Rally Championship drivers' title in the 1982 season.
