The team previously had an eleven season partnership with Petrobas between 1998 and 2008. The firm will supply Williams with a “new specialist motorsport fuel” for the 2015 season, although its logo will feature on this year’s Mercedes-powered FW36 and its team kit.
The deal ties in with Felipe Massa’s move to the Grove-based outfit for the 2014 season. The 32-year-old is the only Brazilian driver in Formula One.
“We are very happy to be going back to the biggest motorsport competition in the world,” said Petrobras president Maria das Graças Silva Foster. “During the 11 years that Williams was by our side we made significant advances in product development, such as Podium gasoline.
“Participating in this competition is a huge challenge, since it requires us to always be ready to meet the highest standards for quality and efficiency demanded by the category. We are very excited to start this new challenge.”
Sir Frank Williams, founder and team principal of the Williams F1 Team, said: “Petrobras and Williams have had a successful partnership before and we are both looking forward to reuniting for 2014.
“Technologically they are very strong and that will be important for the team as the new regulations have made fuel efficiency increasingly important. They are also a very ambitious global company and we are looking forward to working together to further their marketing goals.”
