The GT6 owes its heritage to the four 1964 Le Mans Spitfires. These Spitfires were very successful competition cars aimed at winning their class and giving a bit of stick to MG! Producing 102 BHP at 7,000 RPM, these remarkable cars conquered the 24 hour race reaching top speeds of 134 MPH. David Hobbs and Rob Slotemaker bought in ADU2B in 21st Place overall and 3rd in class averaging 94.7MPH for the whole 24 hours. Unfortunately ADU1B and ADU3B retired after being involved in accidents and not because of mechanical problems and after having been leading their class. ADU 4B didn’t race but was kept as a spare.
