Tony Southgate (born 25 May 1940, Coventry, England) is a British engineer and former racing car designer. He designed many successful cars, including Jaguar's Le Mans-winning XJR-9, and cars for almost every type of circuit racing. He was responsible for the chassis design of Ford's RS200 Group B rally car. Southgate was employed as chief designer or technical director for many Formula One teams for over twenty years. These teams included BRM, Shadow and Arrows. Southgate retired after producing the Audi R8C, which was a major influence in the Bentley Speed 8, which won Le Mans in 2003. He continues to be a regular visitor to current and historic race meetings.
Tony Southgate became interested in motorsport during his engineering apprenticeship and, like many aspiring racing designers in the late 1950s, was a member of the 750 Motor Club. The 750MC was a training ground for motorsport luminaries such as Colin Chapman, Eric Broadley and Brian Hart. In 1962 Broadley gave Southgate his first job, as a draughtsman for Lola Cars. Southgate gained a broad grounding in many areas of motorsport design while at Lola. He was involved in projects as wide-ranging as the lithe, 1.5 litre Lola Mk4A Formula One car and the 5.0 litre Lola T70 sports car. He also assisted with designs for IndyCar chassis, one of which evolved into the Honda RA300 Hondola Formula One race-winner.
