The GT6 is a 6-cylinder sports coupé which was built by Standard-Triumph and based on their popular Triumph Spitfire convertible. Production ran from 1966 to 1973.
In early 1963 Giovanni Michelotti was commissioned by Standard-Triumph to design a GT version of their recently introduced Spitfire 4 (also designed by Michelotti). An unmodified Spitfire 4 was transported to Michelotti's design studios in Italy and late in 1963 the prototype Spitfire GT4 was returned to England for evaluation. The styling of the vehicle was a success but unfortunately the extra weight of the GT bodyshell resulted in extremely poor performance, with the 1,147 cc (70 cu in) Spitfire power unit, and plans for producing the Spitfire GT4 were shelved. However, Michelotti's fastback design for the Spitfire GT4 prototype was (for the 1964 season) adopted by the Triumph racing-programme as it was deemed to provide an aerodynamic benefit over the standard Spitfire body-shape. Fibreglass copies of the Spitfire GT4's fastback were grafted on to the race-modified Spitfires destined for competition. The Spitfire racing programme was successful and, in 1965, resulted in 13th overall and a 1st in class at the prestigi
