Peter Eric Warr (18 June 1938, Kermanshah – 4 October 2010, Sainte-Foy-la-Grande, France) was an English businessman, racing driver and a manager for several Formula One teams, including Walter Wolf Racing, Fittipaldi Automotive, and Team Lotus.
Warr served a period of National Service as an officer in the Guards Division of the British Army, after training at the Royal Military Academy Sandhurst. Following demobilisation he moved into business. Warr joined Lotus Cars in 1958 as a salesman, soon switching to sister company Lotus Components where he handled sales of the company's customer racing cars, quickly rising to become Managing Director. During this period he also enjoyed a career as a racing driver, driving the same Lotus 18 Formula Junior cars that he sold during his day job. As a driver he did not reach Formula One, but he won a Formula Junior race in a Lotus 20 on the 4.8-mile south circuit at the Nurburgring on 28 April 1962, and is famous as the first winner of the Japanese Grand Prix in 1963, driving one of his employer's Lotus 23 sportscars.
Warr was selected by Colin Chapman in late 1969 to be Team Lotus' Competitions Manager in Formula One, and helped mastermind Jochen Rindt and Emerson Fittipaldi's World Championships in 1970 and 1972, respectively. At the end of 1976 Warr moved to the new team set up by Canadian oil magnate Walter Wolf, and oversaw a very successful first year in which Jody Scheckter won three races and challenged for the World Championship. Wolf's fortunes flagged and at the end of 1979 was merged with the Copersucar Fittipaldi team. By mid 1981 Chapman had enticed Warr back to Lotus, where he would remain until 1989.
