Williams F1 became the latest team to show-off their 2012 offering, by releasing the FW34 at the Jerez circuit in Spain this morning.
The new car is a complete overhaul of last year's machine, with the FW34 carrying 'fewer than five per cent of the parts from last year's FW33'.
The car, which was unveiled ahead of the week's testing schedule, features the popular 'step-nose' design, which complies with the regulatory drop in nose height for the 2012 season.
For the up-coming season, Williams have reunited with Renault as engine partner, whom they won four Drivers' and five Constructors' titles with during their previous nine-year partnership between 1989 and 1997.
Williams endured a difficult season last year, scoring just five points and finishing the campaign ninth in the constructors' standings.
For the 2012 season, Bruno Senna will be joining Pastor Maldonado on the paddock, with Senna eagerly awaiting his first ever pre-season schedule.
In a statement on the Williams F1 website, he commented: “This is my ever first pre-season testing programme since I started in Formula One two years ago.
“I’m really motivated and looking forward to working hard and with everyone in the team. I hope we have a successful month testing and developing the car so we arrive in Melbourne as well prepared as possible.”
