His motorsport career started as a racing car driver, before he switched roles to become head of International Formula 3000 team Arden International Motorsport in 1999.
Horner was born into a family involved in the car industry: his grandfather worked as purchasing manager at the Standard Motor Company in Coventry, before establishing an agency with Horner's father to supply components to motor manufacturers in the English Midlands. Horner was privately educated at Arnold Lodge School in Leamington Spa and then Warwick School. He has two brothers, Jamie and Guy.
Having started his racing career in karts, Horner's career in car racing started after he won a Formula Renault scholarship in 1991. He competed in the 1992 British Formula Renault Championship with Manor Motorsport, finishing that season as a race winner and the highest placed rookie. He then moved up to British Formula Three for 1993, finishing second in the Class B Championship for P1 Motorsport and winning five races before moving to the Fortec and ADR teams in 1994 and 1995, and then to the TOM'S team in 1996. In 1996 he also raced in British Formula Two.
