Input: Question: What model car were they using at the Castrol 500? Passage:The second year of Group A in Australia saw the domination of the JPS Team BMW team fade with several other teams pushing forwards. Most spectacularly was the return of Nissan Motorsport Australia (now under the leadership of former Bathurst winner Fred Gibson) with the newly homologated Nissan Skyline DR30 RS turbo. Led by long time Nissan lead driver George Fury they were the main rival for another new team, the John Sheppard run Volvo Dealer Team, a factory supported team which succeeded the Mark Petch Motorsport Volvo team of 1985. The Touring Car Championship became a two horse race between Volvo's Robbie Francevic and Fury. Fury was never able to haul in Francevic's early points lead and Francevic was crowned champion. Francevic was fired from the Volvo Dealer Team by Sheppard the day after the Castrol 500 at Sandown after refusing to drive what he believed would be an un-competitive car which had only been completed at the meeting started. He then returned to the Mark Petch team as they began development of a Ford Sierra turbo. Although Francevic won the ATCC in the car, 1986 was the last time the Volvo 240T was seen in Australian touring car racing.
