The Brawn BGP 001 (originally known as the Honda RA109K) is a Formula One world championship winning racing car, the design of which was started by Honda Racing, and completed and then built by the team after it was renamed to Brawn GP. It was the first and only Formula One car constructed by the Brawn GP team, and was used to contest the 2009 Formula One season. The car won eight out of the seventeen Grands Prix it competed in. It was notable for its unusual double diffuser, and its legality was disputed, though it was ultimately deemed legal by the FIA. This is the first Brackley-based F1 car to utilise Mercedes-Benz engines, which is used by its successor factory team. The BGP 001 was the last Mercedes customer team to win the Constructors' Championship until the McLaren MCL38 in 2024, which was then followed by the McLaren MCL39 in 2025.
The BGP 001 made its competitive debut at the 2009 Australian Grand Prix, where Jenson Button took pole position in qualifying and finished first in the race while his teammate Rubens Barrichello took second place in both qualifying and race. During the first half of the season alone, Button took seven further podiums, including six wins, which, due to a mid-season drop in performance from the team which meant he did not score any further victories, gave him enough momentum to secure his first Drivers' Championship. Barrichello took six podiums, including two wins, though he dropped to third behind Red Bull's Sebastian Vettel.
