Jenson Alexander Lyons Button (born 19 January 1980) is a British racing driver and former Formula One (F1) racer who won the 2009 F1 World Championship driving for Brawn GP. After his Formula One career, he became a champion of the Super GT Series in 2018, driving a Honda car for Team Kunimitsu.
Button began karting at the age of eight and achieved early success, before progressing to car racing in the British Formula Ford Championship and the British Formula 3 Championship. He first drove in F1 with Williams for 2000. The following year he switched to Benetton, which in 2002 became Renault, and then for 2003 he moved to BAR. In 2004 he finished third in the World Drivers' Championship, falling to ninth in 2005. BAR was subsequently renamed Honda for 2006, during which Button won his first Grand Prix in Hungary, after 113 races.
Following the withdrawal of Honda from the sport in December 2008, Button was left without a team for the 2009 season. In February 2009, Ross Brawn led a management buyout of Honda, creating Brawn GP and recruiting Button as a driver. Button went on to win a record-equalling six of the first seven races of the 2009 season, securing the World Drivers' Championship at the Brazilian Grand Prix, having led on points all season; his success also helped Brawn GP to secure the World Constructors' Championship.
For 2010, he moved to McLaren, partnering fellow British racer and former World Champion Lewis Hamilton. After finishing fifth for the team in 2010, Button ended the 2011 season as runner-up, before falling to fifth in 2012. A further four seasons with McLaren resulted in no further victories and his final F1 race was the 2017 Monaco Grand Prix. From the 306 races that Button started he won 15, and took 50 podium finishes.
