Cooper MkI T4

After they had produced their first 500cc racing car Charles and John Cooper toyed with the idea of producing a small sports car based on a similar chassis and in 1947 built one car using a twin-cylinder Triumph motor cycle engine. The project was never pursued, partly because the Triumph engine lacked the power required, but also because of the need to devote more time to developing the race cars. This 1947 Cooper MkI T4 was part of the display of 500cc cars at the Coys International Historic Festival meeting at Silverstone in July 1998.
