Season review
The opening three rounds of the championship continued the story of the previous two seasons with the Ford Sierra RS500's of Dick Johnson Racing teammates Dick Johnson and John Bowe dominating podiums with only the tight nature of the Amaroo Park layout giving another driver a look-in, namely the Nissan Skyline of Jim Richards who held off Bowe in a race long duel to win the season's opening round. Another tight track at Winton Motor Raceway gave Richards his second victory of the year with team-mates Tony Longhurst and Alan Jones putting their Benson & Hedges Sierras ahead of the DJR pair onto the podium. Lakeside Raceway saw a complete upset with veteran Colin Bond winning his first ATCC race since 1978 from former teammate Peter Brock in his Mobil 1 Sierra and Holden Racing Team driver Win Percy in what would prove be Holden's only podium finish of the season. Englishman Percy, a former three time British Touring Car Champion, had taken over the role of team manager and lead driver of the HRT in 1990 and was contesting his first ATCC.Colin Bond made it two in a row at Mallala after Mark Skaife's spectacular debut of Nissan's new, 4WD, twin turbo Skyline R32 GT-R, which was nicknamed "Godzilla", ended with a broken hub after storming to the lead in the early laps. As at Lakeside, Bond's steady, though unspectacular race pace paid off and as others fell away, his Caltex Sierra emerged in front. Peter Brock broke through for his first victory of the year at Wanneroo despite driving with falling turbo boost pressure for the last half of the race which actually helped minimise his tyre wear, while a broken axle to Johnson at Wanneroo saw his points lead surrendered to Richards who finished fourth in his first race of the new GT-R.
Ahead of the Oran Park Raceway Grand Finale, Richards held a three-point lead over two-time defending champion Johnson, with Bond and Brock still a chance being eleven and twelve points behind respectively. Bowe, winless despite his form, was too far behind even if he won and all other contenders retired. Richards, again in the GT-R, dominated Oran Park, making the points calculations irrelevant. Second place allowed Brock to slip past Johnson and Bond into the series runner's up position. After a poor start by Brock, who proved to be the only Sierra driver capable of matching Richards in the Nissan, Richards drove away from the field. Behind Bowe, Longhurst was sixth after an inconsistent season ahead of Glenn Seton's improving Sierra. Percy was the best of the Holdens in eighth ahead of Alan Jones and Gregg Hansford who only had a partial season in Allan Moffat's Eggenberger Motorsport built Sierra.
For the first time since the ATCC changed from a single race to a series of races in 1969, the ATCC did not appear in Melbourne with neither Sandown or Calder hosting a round. The Phillip Island circuit, revived in 1989 for the Australian motorcycle Grand Prix which was a round of the 1989 Grand Prix motorcycle World Championship, held its first ATCC race since 1977.
