The team released a rendering of the FW37 last week, and will run the car for the first time in public in Jerez, with the first test of 2015 starting on Sunday. Williams has opted to give both of its drivers consecutive days in the car rather than alternating them, with Bottas opening the test on the first two days before team-mate Felipe Massa takes over for days three and four.

Susie Wolff has been promoted to test driver and will spend time in the car at the second test in Barcelona, while the team is currently without a reserve driver after Felipe Nasr was handed a race seat at Sauber.
