The "Fuel Quality Standards Act 2000" relating to E85 states that the fuel may only be used in vehicles that have been specifically designed or modified to use E85. These include flexible-fuel vehicles (FFV) and V8 racing supercars. The first FFV available in Australia was the Saab BioPower 9.3 and 9.5 which coincided with United Petroleum launching and selling E85 at two of their service stations in Sydney and Melbourne in 2007. Caltex followed in 2010, launching their E85 product "Bio E-Flex" made specifically for flexible-fuel vehicles. Holden announced at the same time that Caltex E85 would be suitable for vehicles within the Holden Commodore VE Series II range. The Australian V8 Super Cars motor racing series have used E85 since the beginning of the 2009 season.
