Brawn GP — the one‑season Formula One champions of 2009

Origins and formation

At the end of 2008 Honda announced its withdrawal from Formula One. Ross Brawn, who had previously worked with teams such as Ferrari and Benetton, negotiated the purchase of the Honda team and chassis factory in early March 2009. The Fédération Internationale de l'Automobile (FIA) recognised the rebranded operation as a new entrant, allowing it to race in 2009 without the usual entry fee. The existing drivers, management and factory infrastructure remained largely intact, but the team secured new engine supply and sponsorship partnerships to support its campaign.

Key personnel, car and partners

Brawn GP's driver lineup featured Jenson Button and Rubens Barrichello, both retained from the Honda era. The squad ran Mercedes‑branded engines and attracted a mix of technical and commercial partners. Early sponsorship agreements included companies such as Virgin plus other financial and technical backers. The team's 2009 challenger became well known for a distinctive aerodynamic solution that contributed to its early competitiveness.

2009 season and achievements

Brawn GP debuted at the opening round of the 2009 championship and immediately challenged for victories. The team converted strong qualifying performances into race wins and consistent podium finishes, particularly in the opening races. Jenson Button secured the Drivers' World Championship late in the season at the Brazilian Grand Prix, while combined points from both drivers gave Brawn GP the Constructors' title — a rare achievement for a brand‑new entrant.

Technical notes and controversies

• The Brawn BGP 001 featured aerodynamic elements that exploited regulation interpretations and gave the car a performance advantage early in the season.
• Opposing teams raised questions about the design, but it was cleared to race, and rival teams subsequently developed similar solutions.
• Use of Mercedes power units and an experienced technical staff helped the small team maximise the competitiveness of its package.

Legacy and transition

Although Brawn GP existed only for the 2009 season, its impact was enduring. The outfit remains notable for winning both World Championships in its only season of competition. Within months of the title double, the team was acquired by automotive interests associated with Mercedes and re‑entered the sport as a works Mercedes‑branded team for 2010. The drivers — including Jenson Button and Rubens Barrichello — and many staff members moved on, and the Brawn name lives on in histories of remarkable sporting turnarounds.
