For the 2008 season, the Honda F1 team named Ross Brawn as team principal and also announced a new deputy technical director in the form of former BMW Sauber chief designer Jörg Zander. The team retained their drivers from the previous two seasons, Jenson Button and Rubens Barrichello and also recruited Alexander Wurz from Williams.
The RA108 had been a constant mid to rear end car in 2008 testing with Jenson Button saying the car lacked "driveability" as the drivers and team adapted the RA108 to new rules. For the 2008 season, the FIA implemented rules that required all teams to use one gearbox for four races and a standard McLaren Electronic Systems ECU that prevents the use of driving aids such as traction control and engine braking. Ross Brawn had already said the team had a better chance for the 2009 Formula One season as the regulations for 2009 would be totally new.
Button commented on how positively the team developed the RA108. At their final week of testing at the Jerez Circuit in Spain, the team added new aerodynamics, with most of the wings being revised. Head of Race and Test Engineering, Steve Clark, believed the car was a clear step forward.
