Williams Racing F1 - FW43
Williams Racing FW43

Williams Racing has officially revealed its 2020 Formula One challenger, the Williams Mercedes FW43. The FW43 is an evolution of the FW42, with much of the development work carried out throughout 2019 feeding in to the design of this year’s car. Speaking ahead of the 2020 season, Claire Williams, Deputy Team Principal, said: “This year marks a fresh start for the team. We have spent time addressing our areas of weakness and have ensured that we have the right people, structures, procedures and resource in place to deliver competitive race cars. We are all committed to re-building Williams and returning the team to competitiveness. As such, our 2020 campaign is about making progress. The fighting spirit is still very much alive, and this year, everyone will continue that fight until we get back to where we want to be.”

Design Director, Doug McKiernan, commented: “The team at the factory have been working incredibly hard on the development of the car for the 2020 season. We have paid significant attention to understanding the problem areas of the FW42 and we have carefully chosen parts of the car to develop, those that would give us the most performance for the resources we have. The main concept behind the FW43 is that it is a continuous development of the FW42, with no fundamental concept changes to the layout. The most important indicator that we are on the right path will be the level of correlation we have between the tool kit we use to design the car and what the track data is telling us. There has been a healthy development rate in the wind tunnel, and we have found reasonable improvements in the cooling efficiency. The team has addressed the mechanical issues that affected it in 2019, these include the brakes and the overall weight of the car. We have made some good progress across these areas and will continue to focus on them during the season.”

Chief Engineer, Adam Carter, added: “The initiatives that we put in place to drive performance across all disciplines within the engineering department are evident in the design and development of the FW43. It’s been great to see the hard work starting to pay off. The decision to retain some of the core architecture of the FW42 means there has been less resource invested in developing new concepts, which in turn has rewarded the design team with greater bandwidth to optimise their work, evident in both packaging and component detail. By preserving some key parameters, it has allowed for an uninterrupted development programme within Aerodynamics in order to maximise the efficiency of the resources. As we head towards the pre-season tests and then onto the race season, the most important measure will be the progress relative to our peers, along with our intention of continuing our recent record of reliability. Later this week, we will be looking at our single timed lap pace, our long run pace and the feedback from the drivers to understand where we are and what we do next. We have teams, both at the track and back at Grove, that will be delving into all aspects that define that lap time during the pre-season tests to ensure we are in the best possible place ahead of the first race in Australia.”

This approach tallies well with both the team’s situation and the upcoming regulation changes in 2020. After a challenging year, there may be the temptation to try for a radically different approach, but this risks compounding errors when the team found its previous car didn’t meet expectations. If you were to look at the 2019 FW42 without the livery, there were features that were at the same level if not more advanced than many of their rivals. Its not that the car lacked ambition, just that it didn’t work to the level the designers had predicted. This required a back to basics approach to understand what differed in the correlation between design and reality.
