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. ^[2] The car made its competitive debut at the Australian Grand Prix, and was driven by Lance Stroll in his second season with the team; ^[6] and Sergey Sirotkin, making his competitive debut in Formula One. ^[7] The FW41, albeit reliable, lacked the necessary pace to challenge the other cars over the course of the season.

Design and development

In signing Sergey Sirotkin, Williams formed an alliance with Russian racing outfit SMP Racing, which came with financial investment in the team. While discussing the investment, SMP Racing revealed that under the terms of the agreement their investment would specifically be spent on technical development of the FW41 instead of being used to cover the costs of day-to-day operations. ^[8]

Testing and development work was carried out by Robert Kubica. The role was Kubica's first with a Formula One team since his 2011 rallying accident that almost resulted in the traumatic amputation of his arm. ^[9]

The Mercedes-powered Williams FW41 features the mandatory Halo cockpit protection device, painted white so it is incorporated into the team’s livery design, which sports blacker on the front wing, bargeboards and around the sidepods for 2018.

The car had problems with its development mainly being cooling, packaging and the aerodynamics which resulted in its uncompetitiveness.

Competition history

Stroll and Sirotkin in action during the Italian Grand Prix which would turn out to be the only double-points finish for the team that season

Williams had finished fifth in the Constructors Championship in both 2016 and 2017, but saw their performance decline severely in 2018. Although the car had good reliability like Mercedes and Force India, its pace was poor, and the team ended up at the back of the field mostly fighting the Toro Rossos. Their first points came in Azerbaijan when Stroll finished 8th. The team would not score points again until Italy, when Stroll and Sirotkin finished 9th and 10th respectively. They finished 10th and last in the Constructors' Championship, their lowest ever position. However, the seven points they scored exceeded the five points scored in both 2011 and 2013.

Sponsorship and livery

This was the fifth and final Williams car featuring a Martini livery as the team decided to not renew the sponsorship deal. Alcohol laws meant Williams could not use their red Martini stripes in France and Abu Dhabi, instead using a blue livery.
