1991 was the low point for Group A touring car racing in Australia as grid numbers plunged in a harsh economic climate.
Just eleven cars entered the Wanneroo round of the ATCC and just fifteen started the once prestigious Sandown 500.
On track the Touring Car Championship was dominated by the Gibson Motorsport prepared Nissan Skyline GT-Rs of Jim Richards and Mark Skaife.
Tony Longhursts new 2.5 litre evolution spec BMW M3 was the only car to interrupt the clean sweep.
A final round DNF for Richards was not enough to take the title away, despite Skaife scoring more points over the course of the season.
