Williams has become the latest team to launch its 2012 F1 car as the first day of pre-season testing gets underway at Jerez.

The FW34 is the first car to be designed under the new technical team headed by chief operations engineer Mark Gillan and technical director Mike Coughlan after a series of changes were made last year.

Another car to feature a stepped nose design, the new FW34 also has a revised rear end for the new exhaust regulations with the team revealing that fewer than five per cent of parts from the FW33 have been carried over to the new car.

The FW34 is also the car that sees a return of the iconic Williams Renault partnership after the Grove-based team switched engine suppliers over the winter.

Pastor Maldonado returns for a second season behind the wheel, with Bruno Senna replacing countryman Rubens Barrichello in the second seat.
