Williams has announced it has entered into a multi-year agreement with Brazilian energy giant Petrobras ahead of the 2014 Formula 1 season.
The latest name to be added to Williams's growing sponsorship roster ahead of the new season, the deal with Petrobras marks the revival of a successful relationship for the pair having previously been engaged in a technical alliance for 11 seasons between 1998 and 2008.
Petrobras' involvement comes at a particularly fitting time for the company, with Brazilian driver Felipe Massa having joined Valtteri Bottas in the British-based team over the winter.
A return to the sport for Petrobras as a whole, the agreement is likely to see the firm's branding appear on the Williams Mercedes FW36 at this week's Bahrain F1 test, as well as the team environment and apparel. In addition to the visible backing, Petrobras will work with Williams to develop a new specialist motorsport fuel for use by the 2015 season, as per new regulations coming into effect.
"Petrobras and Williams have had a successful partnership before and we are both looking forward to reuniting for 2014” said team owner Frank Williams. “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."
The announcement that Petrobras has entered into a deal with Williams in 2014 comes in anticipation of confirmation that Williams will receive significant backing from Martini Racing this year
, with the Italian drinks' brand set to lend its iconic livery to the cars.
