William Stout developed the first car with an FRP body in 1945. Although the Stout-Scarab never went into commercial production, the vehicle was a breakthrough in thinking that others followed. In 1953, General Motors and the Kaiser-Willys Company both launched production cars with FRP bodies - the Chevrolet Corvette and the Kaiser-Darrin. Corvette is one of the longest-running nameplates in Chevrolet history and GM currently builds as many as 35,000 units a year. The total since 1953 surpassed 1.5 million during the 2007 model year. Composite parts on cars and trucks today range from engine valve covers and rear deck spoilers of sports cars to the cabs and trailers of 18-wheelers.
