Driving from the age of eight, Smith raced at the age of 14 in grass track events, building his own cars. In 1972, aged 17, he passed his test and took up motorsports in racing, rallying and rallycross. In 1976, he progressed to Formula Ford 2000 with the
Patrick Head-designed Sark. Smith was also a motorsport commentator, mainly at
Brands Hatch where he also, age 21, ran the marketing operation. It was during this time he became interested in broadcasting. While still broadcasting, Smith raced in several
British Touring Car Championship races, driving a newly
homologated Sierra Cosworth in 1987, and then alongside
Frank Sytner in 1988 in a
BMW M3. He also won the
Willhire 24 Hour at
Snetterton in 1986, co-driving a
Ford Escort RS Turbo with
Robb Gravett. In 1989, Smith established a
BTCC team known as Trakstar with Gravett and Malcolm Swetnam. They ran two Sierra Cosworths, which had been imported from the Australian Touring Car stable of
Dick Johnson. Gravett went on to become runner up in Group A, but Smith struggled with his recovery from the helicopter crash. However, loss of a major sponsor in 1990 meant that only one car could be run, which was raced by Gravett who became champion. Smith never raced competitively again. ==Racing record==
