HISTORY OF THE CAR
This car is an original 1969 Nerus Silhouette Formula F100 Sports Prototype.
This example is an original works racing car and was in fact designed by Cedric Selzer, Jim Clark’s race engineer in 1963/64. The car has a conventional space frame chassis clad with aluminium panels. Only two Silhouettes were ever made, with a third being made up from spare parts.
The F100 class was announced in UK in 1969 and was conceived along similar lines to Formula Ford with lightly modified production engines and was intended to replace the ill-supported sports racing and GT events at club meetings.
This example is believed to that displayed at the 1970 Racing Car Show. It is the first car built by the factory and is believed to have been raced by Nick Cole, achieving the remarkable statistics of always finishing in first or second place in 10 of the eleven rounds in the 1970 series.
