Group D Production Sports Cars

Group D Production Sports Cars was a CAMS motor racing category current in Australia from 1972 to 1981.

The Group D category catered for series-production type automobiles, other than those eligible to compete as Touring Cars, which were:

Recognised by the FIA as Group 3 or Group 4 cars, or
Of a type of which at least 50 examples existed in Australia, or
Of a type which CAMS deemed to be eligible

Bodywork could be of an open or closed type and was required to provide adequate accommodation for a minimum of two persons. The original design of the cylinder-block, cylinder-head, transmission and suspension had to be retained and forced induction was permitted only if fitted as standard by the manufacturer. Minor changes to bodywork, mudguards and interior trim were permitted. A 5000cc engine capacity limit which was applied at the time of the introduction of the category was later raised to 6000cc.

Cars from the Group D Production Sports Cars category were eligible to compete in Australian Sports Car Championship races alongside those from the Group A Sports Cars category from 1972 to 1975 and in May 1975, Production Sports Cars contested the revived Australian Tourist Trophy held at Calder Raceway. In 1976, Group D became the sole category to contest the Australian Sports Car Championship, a situation which applied through to 1981. The category was discontinued at the end of that year and the Group D designation was applied to a new category for GT Cars from 1982.
