Williams has launched its 2011 livery at its factory in Didcot.
New sponsor PDVSA, the state-owned Venezuelan oil company, features prominently and the livery as a whole is a nod towards the Rothmans-sponsored Williams of the mid-1990s. However, the team has mainly stuck to its corporate colours of blue and white.
The car itself was launched at the Valencia test three weeks ago and has already clocked up 3,800 kilometres of testing in its interim livery.
Race drivers Pastor Maldonado and Rubens Barrichello will continue the development of the FW33 at the final pre-season test in Barcelona next month.
