February 18th, 2014 (GMM).- Williams on Tuesday finally confirmed long speculation the Brazilian oil company Petrobras will return as a sponsor in 2014.
It has been rumoured for some time that Petrobras, having backed the Grove outfit between 1998 and 2008, would be wooed back to Williams by the signing of Brazilian Felipe Massa.
The team announced the deal on Tuesday.
"Petrobras and Williams have had a successful partnership before and we are both looking forward to reuniting for 2014," said Sir Frank Williams.
A media statement said Williams' Mercedes-powered FW36 will feature Petrobras logos, while a new fuel will be developed for use in F1 in 2015.
"Technologically they are very strong and that will be important for the team as the new regulations have made fuel efficiency increasingly important," team founder and boss Williams added.
In a different note, it is expected that Williams will launch its new Martini livery in Bahrain.
Earlier, with the iconic Italian drinks brand set to return to formula one in 2014, it was believed the once-great British team would only officially unveil its new title sponsor and much-anticipated Martini livery ahead of the season opener in Australia.
But, actually, Williams - having tested its new Mercedes-powered FW36 in all-blue colours so far - said only that it would launch its race livery in time "for" Australia, not necessarily "in" Australia.
Indeed, Germany's Auto Motor und Sport reports that the official wraps will come off the new partnership "during the second week of testing in Bahrain", set to take place in the island Kingdom late next week.
The end of pre-season running in Bahrain will then start a mere two-week countdown before the red lights go out on the Melbourne grid.
Correspondent Tobias Gruner said the 'Williams Martini Racing' 2014 livery will include the iconic white, blue and red Martini stripe, made famous by the brand's involvement over decades in F1, Le Mans and rally.
