2025 Williams FW47 F1 car conducts shakedown at Silverstone

• Williams has revealed the FW47 as its contender for the 2025 Formula 1 season
• The FW47 will be piloted by Carlos Sainz and Alex Albon in the new season
• Williams also has a new title sponsor, Atlassian

Williams provided a sneak peek of its 2025 Formula 1 car, the FW47, on Friday following an initial shakedown test at the Silverstone Circuit in the U.K.

The car still wears temporary livery, as the final design won’t be revealed until the special F1 75 Live event on Feb. 18 at London’s The O2 entertainment precinct, celebrating this year’s 75th anniversary of F1. Prominently displayed on the livery is the logo of new title sponsor Atlassian, the Australian software company.

McLaren has also given an early look at its new contender, the MCL39.

Once a dominant force in F1, with seven Drivers’ Championships and nine Constructors’ Championships to its name, Williams has struggled in recent years, finishing near the bottom of the standings. In 2024, the team placed second to last, ahead of only Sauber.

However, there’s renewed optimism with Carlos Sainz joining the squad this season from Ferrari, where he was replaced by Lewis Hamilton. Sainz, who finished fifth in the standings last year, takes the seat previously held by rookie Franco Colapinto, who joined Williams midway through last season after Logan Sargeant was dropped. Sainz will race alongside Alex Albon, who finished 16th in 2024.

The 2025 F1 cars retain most of the same design regulations as last year’s models, with power unit rules remaining unchanged ahead of the new regulations set for 2026. Williams continues to source its power unit from Mercedes-Benz AMG, featuring a turbocharged 1.6-liter V-6 paired with two motor-generators—one on the driveline and another integrated with the turbo—delivering a peak output of approximately 1,000 hp.

The FW47 is set to hit the track alongside the rest of the 2025 grid at the Bahrain International Circuit on Feb. 26 for pre-season testing. The season kicks off with the Australian Grand Prix on March 16. A total of 24 races are scheduled this year, including three U.S. stops in Miami, Austin, and Las Vegas.
