The design of the Williams FW25 was a marked departure over its predecessor, and was a completely new design compared to the Williams FW24, something that had not done between and . New to the 2003 design team was ex-Ferrari aerodynamicist, Antonia Terzi, who worked with existing designer Gavin Fisher after the departure of ex-chief aerodynamicist, Geoff Willis.
== Season summary ==
Although the car could have easily won its first Grand Prix during the but for a costly spin by Colombian driver Juan Pablo Montoya, the car did not establish itself amongst the frontrunners on the grid until the where Montoya led before retiring with engine failure. Until that race, both drivers complained about understeer due to flaws in the car's design. Montoya cited the FW25 as a favourite of his, praising the balance and the driveability with the powerful BMW engine which suited his aggressive driving style.
A new, wider front tyre introduced by Michelin at the unlocked the potential of the FW25, which would win that race, score a double-podium at the , then go on to score dominant 1-2 victories at the at the Nürburgring, and the next race, the at Magny-Cours.
A change to the front tyre width (resulting from a protest lodged by Michelin's rivals Bridgestone, through the Ferrari team, after the ) caused controversy through the paddock, with Williams tipped to lose their competitive edge after that race due to a slimmer tyre design being raced at then at Monza being seemingly at odds with the wider tyre that Williams brought with great effect to the Monaco Grand Prix. Despite Montoya's second place at Monza, being able to stay with eventual World Champion Michael Schumacher's throughout the whole race, the FW25 would not win a race in the final three races of the season, the , and took place after the tyre redesign. In fact, after Montoya's second place at the Italian Grand Prix at Monza, the FW25 would not earn another podium in the 2003 season, although Montoya led the final race at Suzuka before retiring with a hydraulics problem.
