The Williams FW41 is the Formula 1 - racing cars of Williams for the Formula 1 2018 World Cup . It was presented in London on February 15, 2018 .

The name of the car consists of the initials of the team founder Frank Williams and a consecutive number.

Technology and development

Like all Formula 1 vehicles of 2018, the FW41 is a rear-wheel drive monoposto with a monocoque made of carbon fiber reinforced plastic (CFRP) . In addition to the monocoque, many other parts of the vehicle, including the body parts and the steering wheel, are made of CFRP. The brake discs are also made from a heat-resistant carbon fiber reinforced composite material.

The FW41 is the successor to the FW40 . Since the technical regulations for the 2018 season remained largely stable, the vehicle is largely a further development of the previous model.

The FW41 is driven by a in the center of the vehicle -mounted 1.6 liter V-6 engine of Mercedes with a turbocharger and a 120  kW strong electric motor , so it is a hybrid electric vehicle . The car's sequential gearbox has eight gears. The gear change is triggered by paddles on the steering wheel. The vehicle has only two pedals, an accelerator pedal (right) and a brake pedal (left). Just like many other functions, the clutch , which is only used when starting from a standstill, is operated via a lever on the steering wheel.

The total width of the vehicle is 2000 mm, the width between the front and rear axles 1600 mm, the height 950 mm. The front wing has a width of 1800 mm, the rear wing of 950 mm and a height of 800 mm. The diffuser has a total height of 175 mm and a width of 1050 mm. The car is equipped with 305 mm wide front tires and 405 mm wide rear tires from the standard supplier Pirelli , which are mounted on 13-inch wheels.

Like all Formula 1 vehicles since 2011 , the FW41 has a Drag Reduction System (DRS), which reduces the drag of the vehicle on the straights by flattening part of the rear wing , if it is allowed to be used. The DRS is also activated with a switch on the steering wheel of the car.

Unlike its predecessor, the FW41 is equipped with the Halo system , which provides additional protection for the driver's head. This system increases the weight of the vehicle to 733 kg. The eye-catching fin on the engine cover that the previous model had is much smaller due to a change in the technical regulations. The rear wing is now attached to two struts, the FW40 only had one central bracket.

Painting and sponsorship

Like its predecessor, the FW41 is predominantly painted in white, with stripes based on the logo of the main sponsor Martini in various shades of blue with a slightly wider red central stripe that run from the front wing attachment to the engine cover. The Martini logo is also attached to the rear wing, otherwise the front and rear wings are painted black.

The Unilever Group advertises its Rexona brand on the side pods and front suspension, and the vehicle also features sponsor stickers from Acronis , Joseph Cyril Bamford , Oris , Pirelli, SMP Racing and Symantec .


Williams competes again with Lance Stroll in the 2018 season . His new team-mate is Sergei Sirotkin , who was a test driver at Renault last year and is making his debut as a regular driver in the Formula 1 World Championship. He succeeds Felipe Massa , who ended his career in the Formula 1 World Championship.
