The 2003 Williams FW25 was a reasonably successful BMW-engined car that took four poles and four wins from the 16 races that year. It was a completely new design for Williams that suffered with understeer until tire supplier Michelin provided a widening front tire to produce more grip. The advantage was removed after a complaint by Ferrari and the car struggled in the final two races of the season as it had before the updated tires.
