Terry started his karting career in the 1960’s after a family tragedy persuaded him not to take up motorcycle racing. His talent was immediately obvious and in his debut season the young Londoner won the 1966 British Junior Championship. He went on to win the title in the following two seasons, creating history as he did so. In the 1970’s Fullerton turned his attentions to international competition. In 1973 he was crowned RAC British, CIK. FIA European and World Champion. Victory after victory followed, with Terry winning races across the globe.
In 1978 he was in his prime and became the official factory driver for the British chassis manufacturer Zip Kart and for Italian engine manufacturer DAP. In this year a precociously talented young Brazilian joined him and then the famous rivalry between Senna & Fullerton began, which was to last for the next 3 years.
After retiring in 1984, Terry became a team owner and leading kart manufacturer, thus starting to develop the talent of drivers, competing under his name. Name like Allan McNish, Ralph Firman, Daniel Wheldon and Anthony Davidson reached the pinnacles of single-seater racing, reinforcing Terry’s reputation for helping talented teenage karters to achieve their maximum potential was sealed.
