After missing out the first pre-season test at Jerez, the Williams F1 Team finally unveil their 2013 challenger, the FW35, ahead of the second test at the Circuit de Catalunya.
Williams ran a modified version of last year’s car at the opening test having decided to continue with the development work on the FW35. The Jerez test still provided useful knowledge especially the new Pirelli tyres.
The FW35 retains the Renault engine for this season and features aggressive undercuts on its sidepods.
“Given the rule stability over the winter,” said 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 1 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 on last year’s car, the FW35 is 80 per cent new, with a new gearbox, rear suspension, radiators, floor, exhausts, bodywork and nose.
Williams returned to the top step of the podium after seven win-less seasons when Pastor Maldonado won last year’s Spanish Grand Prix.
But inconsistent form meant this breakthrough was not reflected in the championship standings, with Williams only eighth in the constructors’ come the end of the 2012 season.
Maldonado stays on for 2013, with the highly-rated rookie Valtteri Bottas promoted from the reserve driver role as a replacement over Bruno Senna.
