At the car's launch, Ross Brawn stated that the F2005 was an evolution of previous cars and design ideas simply adapted to the new regulations for the season. Minor changes had been made over the previous car to improve airflow and conserve the tyres as much as possible. Originally intended to debut in Spain, the F2005 was pressed into service earlier in Bahrain, once it became clear that Renault and McLaren had superior cars and better pace.
