TheAustralian National Formula (often abbreviated to ANF) was an Australian motor racing category which was introduced by theConfederation of Australian Motor Sport in 1964 and remained current until the end of 1969. It had replacedFormula Libre as the Australian premier racing formula.[1]
The Australian National Formula specified single seat racing cars fitted with unsupercharged engines of no greater than 2.5 litres capacity running on commercially available fuel.[2] This encouraged the use of engines such as theCoventry Climax FPF unit which had been prominent in the 2.5 litreFIAFormula One category prior to the downsizing of that formula for 1961. The Australian National Formula was renamed for 1970, officially becomingAustralian Formula 1 (AF1).[3]
TheAustralian Drivers' Championship (for the CAMS Gold Star award) and theAustralian Grand Prix were both open to drivers of Australian National Formula cars throughout the life of the formula, i.e. from 1964[4] to 1969.[5] The formula was also utilised for theTasman Cup series during these years.[6][7]
