Williams has become the first F1 team to reveal its 2017 design via a YouTube video published by Autosport.
The FW40 broke cover on Friday morning in a video published by the magazine that showed a rendering of the new car from several different angles. The car features restyled front and rear wings that are in conformity with this year's regulations aimed at increasing downforce and reducing lap times by several seconds.
It also features swept back sidepods, larger barge boards and a wider track. However, the concept of the nose appears to be largely unchanged from its predecessor the FW38, with a small tip still protruding from the front of the car in order to comply with regulations regarding the height of the nose.
The FW40 will be raced by Felipe Massa and Lance Stroll this year and will complete its first day of official testing on February 27 at the Circuit de Catalunya. It is named in recognition of Williams 40th year in F1 after the team elected to skip the FW39 name and go straight to the FW40 this year.
