The aerodynamic C.S.C. sports car never really passed the prototype state but was well thought out. Its tubular chassis had all-independent suspension by wishbones and transverse leaf springs. The engine fitted to the prototype was a 647cc B.S.A. vertical twin motorcycle unit, driving through a B.S.A. 4-speed gearbox to the rear wheels via chain. Production cars were to have 750cc Royal Enfield engines with Albion 3-speed transmissions and the top speed was quoted at 75mph. By 1955 C.S.C. had developed a chassis for Austin A30 components, fitted with a Rochdale fibreglass body.
