The Brawn BGP 001 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.
