Williams will sport a Gulf livery selected by fans at three Formula 1 grands prix later in 2023.
Gulf became a Williams partner this year but so far its presence has only featured minimally on the FW45.
Williams and Gulf have now designed four liveries – entitled Bolder Than Bold, Visionary, Contemporary and Heritage – that can be voted on by fans.
The livery that receives the most votes will be used at grands prix later this year in Singapore, Japan and Qatar.
There will be three rounds of voting, with the first round opening today (Friday), and the winning livery will be announced on July 12 at the Goodwood Festival of Speed.
“I’m excited to announce the livery vote as part of our partnership between Gulf and Williams Racing,” said Williams Team Principal James Vowles.
“The winning livery will showcase two iconic motorsport brands coming together.
“Our fans have the opportunity to create motorsport history with their livery decision, bringing this partnership to life.
“I can’t wait to see the winning design and watch the Williams Racing fans cheering the team on.”
Gulf was previously involved in a special livery when it partnered McLaren at the Monaco Grand Prix two years ago.
“Gulf’s iconic colours have created stunning liveries throughout motorsport history, and this year is set to be no different,” said Gulf Oil CEO Mike Jones.
“We are incredibly proud to announce that a Gulf livery will be running on the Williams Racing cars at the Singapore, Japanese and Qatar Grands Prix in 2023.
“This project is all about giving fans control and placing them at the centre of our partnership with Williams Racing.
“We feel strongly that each theme and livery will go down extremely well and look forward to seeing which one the fans choose.
“We hope that Gulf and Williams Racing fans alike love this vote and get excited about their role in choosing the latest Gulf livery.”
