The Triumph TR 6 was the continuation of the TR2 to TR5 series. At the end of the 1960s, Triumph was incorporated in the British Leyland concern. As the Austin Healey was no longer manufactured and as the sales of the TR5s declined, the need of a new roadster was felt.
The TR 5’s bodywork was given to Karmann in Osnabruck for improvement. They made alterations to the wings and to the front and rear ends of the car, which was originally designed by Michelotti.
