Australian Touring Car racing changed to International Group A rules in 1985, and Goss scored his second and last ourtight Bathurst win that year with West German co-driver Armin Hahne in one of a three-car assault on the Great Race by Tom Walkinshaw's TWR team using the 1984 ETCC-winning V12 Jaguar XJS' (Walkinshaw had been stung by the bad showing in 1984 and was determined to bring his own team back to conquer the race). Goss, installed by Walkinshaw as lead driver of the team's third car (#10), actually qualified fastest going into Hardies Heroes, giving lie to those who believed he was past his best as a driver and that Walkinshaw had made an error by having him drive. He ended up 6th in the Top Ten run-off after mistakes on both laps (1985 was the last year that cars were given two laps in Hardies Heroes).
