Jaime Alguersuari began karting at the age of eight in his native Spain and it wouldn't be long before he became the youngest-ever driver to make a Formula 1 race appearance and the first Spanish driver to follow in the footsteps of Fernando Alonso. After success in the Formula Junior series and Formula Renault, the Spaniard moved into British Formula Three in 2008, once again making records by becoming the youngest-ever driver to take the championship during his debut year, securing five wins along the way and earning him a Formula 1 test with Red Bull. The following year he competed in Formula Renault 3.5 Series but was called up to replace Sebastien Bourdais at the Toro Rosso Formula 1 team from the Hungarian Grand Prix onwards. A competent F1 debut saw him retain the drive for 2010, which produced some strong performances including two top-10 finishes. He remained with the team for 2011 before switching to become the test driver for F1 tyre manufacturer Pirelli.
