Williams has broken cover with the FW44 at Silverstone after revealing its new livery earlier on Tuesday on an F1 2022 show car.
The first on-track images of the FW44 have been shared by Williams with Nicholas Latifi completing a shakedown test in the wet conditions at Silverstone.
Asked in a media session including GPFans why the team hadn't revealed its actual car at the launch, Williams team principal and CEO, Jost Capito, explained: "We worked on the livery and we wanted to have that perfect and that is why we could only do it on the show car because it took a while to do."
Confirming the team's development was going to plan and the absence of the true FW44 at the launch was not a result of delays or the car being unfinished, Capito added: "It is all on plan.
"It should have run a bit earlier today but we had an issue on the electronics that had to be solved and it took a bit longer so we will start at two instead of at one and that is it.
"I accept this one hour delay!"
