Williams became the final team to launch their 2013 car today in Barcelona, unveiling the FW35 in the early hours ahead of the first day of testing at the Circuit de Catalunya. The car is an evolution of the previous racer, but Williams claim it has 80% new parts, including gearbox, suspension and exhaust. The launch car has the modesty panel to cover the stepped nose, which leads to an unusual design where the front wing uprights are more prominent than you might expect.

Along with a new car, the team confirmed an extension of their partnership with recruitment firm Randstad, as well as a brand new deal with financial information group Experian.

Team Principal, Frank Williams said: “We will have to wait until Australia to truly see what we have, but we believe it is step forward from last year’s car which was also a very competitive vehicle. Pastor is a delightful character who is a massively determined racer, whilst Valtteri is quieter but still waters run deep and he is a highly gifted driver.”
