Its red, white and blue livery represents a major departure from the colour scheme as seen on the FW42.
Williams is coming off the back of a disappointing 2019 season where it finished last in the constructors’ championship with just a single point scored by Robert Kubica in the German Grand Prix.
The outfit endured a particularly difficult start to the year when its new car was late for pre-season testing, and it parted company with then technical chief Paddy Lowe soon after.
Its problems prompted the team to change its processes and conduct a reshuffling of staff, and it is all set to make the start of testing now, with the car having already run in a Barcelona shakedown.
“This year marks a fresh start for the team,“ said deputy team principal Claire Williams.
“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.”
Hopefully the new FW43 will turn around the disappointing and frustrating past year with a solid performance in 2020. Best of luck Williams.
