LDS (automobile)
LDS is the name given to various single seater racing specials built for the South African Formula One Championship. The "specials" were built by Louis Douglas Serrurier, hence the name. The Mark 1 and Mark 2 models were based on Cooper designs, whilst the Mark 3 was based on the Brabham BT11. Mark 1 and Mark 2 models used Alfa Romeo 1.5-litre straight-4 engines.
A total of eight LDS cars participated in five World Championship Grands Prix. They did not score any World Championship points.
