F1: Williams to run first test session with 2012 car

By ,

The Williams F1 Team will present its 2013 car, the FW35, on Tuesday February 19 in Barcelona, after the first winter test session.

The new Renault-powered car will be unwrapped by team drivers Pastor Maldonado and Valtteri Bottas in the paddock of the Circuit Catalunya.

For the earlier Jerez test starting on February 5, the team will run one of last year's FW34-Renault in order to test a number of key development parts in preparation for the launch of the new FW35.

However, the FW34 will display 2013 sponsors' livery.
