The LDS racing cars were built by Louis Douglas Serrurier, a South African racing driver and engineer, for the South African Formula One Championship. Serrurier built a total of 10 LDS cars from 1962 to 1965. The first two models, Mark 1 and Mark 2, were based on Cooper designs and were powered by Alfa Romeo 1.5-liter straight-4 engines. The Mark 3 was based on the Brabham BT11 and used a Climax 2.7-liter straight-4 engine.
The LDS cars competed in the South African Formula One Championship as well as in international races, including five World Championship Grands Prix. However, they did not score any World Championship points. The LDS cars were known for their distinctive white and blue livery, which featured the South African flag.
After the 1965 season, Serrurier stopped building cars and sold the remaining LDS cars to other South African teams. The legacy of the LDS cars lives on in the history of South African motorsport.
