Presentations of new cars: Williams FW43February 17, 2020
Williams team spent the season 2019 extremely unsuccessfully – and in 2020 hopes to at least partially rehabilitate, although there is little hope for it – the engineering and financial resources of the team have recently become seriously depleted.
Many sponsors left, but ROKit, the title partner of the team, remained, the contract with Sofina Foods was expanded, the founder and head of which is Michael Latifi, father of the new team racer Nicholas Latifi, a contract was signed with Lavazza and Crew Clothing Company.
On the morning of February 17, Williams introduced a new car, posting on the website her photos and comments of the leadership. On the same day the first break-in in Barcelona took place – George Russell got behind the wheel. FW43 was the development of last year’s FW42, but the team tried to fix its weaknesses.
Claire Williams, Team Leader: “This year is a new start for us. We tried to eliminate weaknesses in the team, provided the necessary specialists, procedures and resources for the production of competitive racing cars.
Our goal is to rebuild the team, returning Williams to the fight, making progress in the 2020 season. “The fighting spirit is still alive, we will continue the struggle to return to the positions we deserve.”
Doug Makkirnan, chief designer: “The entire team at the base worked seriously with the 2020 machine. We paid special attention to understanding the problem areas of last year’s FW42 and choosing those nodes and components that will provide the greatest performance taking into account the resources available to the team.
At the heart of the FW43 concept is the continued development of the FW42 without fundamental changes to the layout of the machine. An important indicator of the fidelity of our chosen path has become a good correlation between the tools that we use to create the machine and the data on the real track.
Work in the wind tunnel continues. We have made progress in improving the efficiency of cooling systems. The team analyzed the mechanical problems that prevented us in 2019, including the operation of the brakes and the large total weight of the car. We have made progress in these areas and will pay attention to them during the season. ”
Adam Carter, chief engineer: “The initiatives that we have implemented have improved the efficiency of all the technical divisions of the team and helped in the design and development of FW43. It’s nice to see when hard work bears fruit.
The decision to preserve the basic architecture of the FW42 saved resources on the development of new concepts, giving designers a chance to focus on optimizing the layout of the machine and individual components. Preservation of some key parameters allowed the continuation of the aerodynamics efficiency program.
In winter tests and throughout the season, the most important assessment will be the progress of the machine relative to our main rivals, while maintaining our record reliability.
Later this week we will evaluate the speed of the car in one fast lap and at a long distance, we will receive racers’ comments that will help us to understand where we are in comparison with our rivals, and what needs to be done next. The team’s employees on the highway and at the base in Grove will appreciate the pace of the car in tests to maximize its capabilities for the first race of the season in Australia. ”
