CTG was an engineering company founded by Cyril Malem and based in Wimborne in Dorset. They began constructing racing cars in 1971 and from 1972-78 were subcontractors for Chevron as well as building many cars for other people including the monocoque for the 1974 F1 Fittipaldi FD04 and in later years 2 F1 BRM chassis as well as work for Ralt. In 1977 CTG began constructing their own cars for FF 2000 where they won several races with a variety of drivers. In 1976 in conjunction with freelance designer Len Terry and Viking team owner Tore John Helle (who laid out the design parameters) they built 5 Viking F3 cars (see Viking entry) for the Swedish team to compete in European and Swedish F3 races.

The story of the CTG F3 is a little convoluted. By the middle of 1976 the Viking team were in financial trouble and Len Terry and CTG unsuccessfully sought the backing to run 1 or 2 cars at the end of the season. The Viking design was rebuilt in 1977 as a Technic (see Technic entry) with only one qualifying attempt to its name. CTG announced a new F3 car for 1978, the CTG 378, and at the end of 1977 a car was tested that was called a CTG which appears to be the Technic renamed. The 378 did not materialise and CTG disappeared from F3 racing.
