Ford Sierra RS500 Cosworth BTCC

Ford Sierra RS500 Cosworth BTCC (Class A) 1989

In August 1987 the Sierra RS500 Cosworth was homologated. Ford took pole position in all the remaining six 1987 World Touring Car Championship events and was first over the finish line in four of them. The works Eggenberger Motorsport team won the entrants' World Championship, although the team's cars were disqualified from the 1987 Bathurst 1000 in Australia for wheel arch panel irregularities. These had been deemed legal in every other race that year however this deprived Klaus Ludwig and Klaus Niedzwiedz of the drivers' title. Eggenberger won the 1989 Spa 24 Hours.

Robb Gravett won the 1990 British Touring Car Championship in a RS500. The BTCC points system was such that divisions below the Sierra (3500cc & under, 2000cc & under) would gain more points for a class win therefore although the Sierra finished first in 9/12 rounds of the 1987 season and first in every race from 1988 to 1990 it only took the drivers title once in 1990.
