Although Team Surtees is better known for its Formula 1 cars, it started life with a Formula 5000 design and quickly found itself in race car production. The sophisticated and successful Len Terry TS5 was slightly, almost imperceptibly, upgraded in 1970 as the TS5A and then followed by the Formula 1 TS7 design that summer. The Formula 5000 design was a great success, though Team Surtees may have made a mistake by not taking a more significant step forward with their 1970 car. For 1971, a F5000 adaptation of the neat little TS7 was sold as the TS8. Sales declined noticably but the old TS5s and TS5As still made Surtees one of the most numerous on US grids.
In 1972, Team Surtees again built a F5000 car based on the previous season's F1 car, this being the TS11 based on the side-radiator TS9B. Although successful on the track, the TS11 attacted few buyers and Surtees' attention turned to his highly successful F2 TS10 and the later TS15s.
Rumours swirled of a TS17 F5000 car for 1974 but it was never seen and almost certainly never built.
