1972 Australian Manufacturers' Championship

The 1972 Australian Manufacturers' Championship was a CAMS sanctioned national motor racing title for car manufacturers. It was contested over a five-round series.

All rounds were open only to Group E Series Production Touring Cars. Entries were divided into four classes, split via "CP Units", where the engine capacity of the vehicle (in litres) was multiplied by the retail price of the vehicle (in dollars) to give a CP (Capacity Price) Units value for each model. For each round other than Bathurst, championship points were awarded 9,8,7,6,5,4,3,2,1 in each class with bonus points awarded for outright placings on a 4,3,2,1 basis. For the Bathurst round, points were awarded 18,16,14,12,10,8,6,4,2 in each class with bonus points awarded for outright placings on a 4,3,2,1 basis.
 * Class A : Up to 3,000 CP Units

 * Class C : 9,001 to 18,000 CP Units
