Australian Dick Johnson purchased two Mustangs built by the German Zakspeed team in mid-1984 for use through 1985 and 1986 Australian Touring Car seasons as Ford Australia did not homologate either the Australian built Ford XE Falcon or its replacement, the XF Falcon, for racing. Johnson had a race win in the Group A support race for the 1985 Australian Grand Prix, as well as several placings in the 1985 and 1986 Australian Touring Car Championships. The Mustang's competitive life in Group A came to an end at the end of 1986 and was replaced in 1987 by the European designed turbocharged Ford Sierra RS Cosworth.
