Williams F1 launched its 2013 race car the FW35, at the Circuit de Catalunya in Spain on 19th February 2013 after completing the first test of the winter with a modified FW34. A different nose cone and the new gearbox were both run with this car, displaying excellent reliability before getting the FW35 on track.

“Given the rule stability over the winter,” says Williams Technical Director Mike Coughlan, “I’m pleased with the gains that we’ve been able to make with this car. It’s a better, more refined Formula One car than the FW34 and I think everyone involved in the project can feel proud of the work they’ve done.”

Despite being an evolution of 2012’s car, more than 80 per cent of the FW35 is new. It has a new gearbox, new rear suspension, new radiators, a new floor, new exhausts, new bodywork, a new nose and a significant amount of weight has been saved as well.

Still, despite being launched later than other cars, the Williams FW35 underwent radical changes during winter testing. First, an exhaust channel bridge had to be removed after the first test as the FIA found it illegal, and on the penultimate day of testing, the team overhauled the sidepods to introduce an exhaust ramp, following Red Bull Racing and Lotus F1.
