The Williams FW41 is a Formula One racing car designed by Paddy Lowe and Dirk de Beer for the Williams team, to compete in the 2018 FIA Formula One World Championship. The car made its competitive debut at the Australian Grand Prix, and was driven by Lance Stroll in his second season with the team; and Sergey Sirotkin, making his competitive debut in Formula One. The FW41, albeit reliable, lacked the necessary pace to challenge the other cars over the course of the season.
