It was designed by Loïc Bigois, in similar respects to all the other cars on the grid with a moulded carbon fibre and honeycomb composite monocoque and a front and rear wishbone and pushrod activated suspension system.

The BGP 001 had a different central channel to its diffuser with the shape of the structure being used to create advanced type of double-decker design.

[7] At the first race of the season in Australia an official complaint was launched by Renault, Red Bull and Ferrari against the diffusers of the Williams FW31, Toyota TF109 and the BGP 001 saying that they were illegal.

On Wednesday 14th the ICA concluded that the diffusers' designs were legal and complied with the 2009 regulations, rejecting the teams' appeal.

[19] Given the limited budget and development time, only three chassis were ever made (larger teams, such as McLaren built as many as eight): one for each driver and a spare.

Chassis 02 was painted silver after 2009 for the 2010 launch of Mercedes GP and used as a demonstration car for two years before being returned to its previous Brawn livery.

[citation needed] This was followed by Button topping the timesheets on the third day by over a second clear of Felipe Massa's Ferrari, completing 130 laps.

[24] On the final day of the test, Barrichello replicated the feat of his teammate; topping the time sheets by over eight-tenths of a second from Nico Rosberg's Williams, completing 110 laps.

[25] With the testing moving to Circuito de Jerez, Brawn continued to set the pace, six-tenths clear of Renault's Fernando Alonso, completing 107 laps.

[citation needed] Alonso topped the timesheets on day two, edging Barrichello into second leaving Button third, as the drivers completed 74 laps between them.

[citation needed] On the final day, Button topped once again, two-tenths clear of Rosberg with Nelson Piquet Jr. and Lewis Hamilton further behind.

[28] The car achieved podium finishes in all of the first 8 races of the season with Button winning 6 times, at the Australian, Malaysian, Bahrain, Spanish, Monaco and Turkish Grands Prix.

At the first race of the season in Australia, an official complaint was launched by Renault, Red Bull and Ferrari against the diffusers of the Williams FW31, Toyota TF109 and the BGP 001 saying that they were illegal.

[9] There was an appeal launched on the 'diffuser cars' but was rejected by the FIA on Wednesday 14 April 2009 leaving the diffuser on the BGP 001 clear to race.

Another notable incident occurred at the Hungarian GP, a suspension spring came off Barrichello's car during the third qualifying period and struck Felipe Massa's helmet that left the Ferrari driver briefly unconscious as he crashed head-on into a tyre barrier, sustaining a serious head injury.

[35] At the 2009 Spanish Grand Prix, the car sported imagery and the logo of the film Terminator Salvation on its rear wing for the entirety of the race weekend.

[38] For the 2009 Brazilian Grand Prix Brawn GP closed a deal with Petrópolis brewery to stamp their colours and beer brand Itaipava on both cars.
