More good news for Williams:
Williams have announced a "new multi-year partnership agreement" with Brazilian oil company Petrobras.
The deal, which covers a technological collaboration as well as sponsorship, reunites the pair following an 11-year partnership that started back in 1998. It also comes in the wake of Felipe Massa's arrival at Williams - the Brazilian currently his country's only driver on the F1 grid.
The team's new FW36 was noticeably shy of sponsor logos when it debuted at Jerez three weeks ago; Williams are, however, refusing to comment on speculation that a major deal with Martini will also see the Italian drinks company's iconic striped livery feature on the car this season.
