Triumph Spifire GT4. In 1963 Michelotti was commissioned to design a GT version of the Spitfire. The GT4 was too heavy and the project halted. But fibreglass versions of the GT4 bodywork were used for the works racing team, achieving a class win in the 1965 Le Mans 24hour race. Further development led to the 2-litre GT6 in 1966.
