London: The controversy over Mercedes' in-season testing has been settled and Formula One's focus this weekend shifts to the British Grand Prix and Sebastian Vettel strong bid to win a fourth-straight title.
Coming off a comfortable win at the Canadian Grand Prix, Vettel has shaken off some early season headaches with tyres and his Red Bull team seems ready to dominate. Already the youngest world champion, the 25-year-old German has a chance to match the exploits of F1 greats Juan Manuel Fangio and Michael Schumacher by winning four drivers' championship titles in a row.
But it won't be easy. Silverstone has not been kind to Vettel in recent years. He has only won there once, in 2009, on what is essentially the team's home track - it's located 30 kilometers (19 miles) from Red Bull's factory in Milton Keynes - and had to watch his teammate Mark Webber claim victory two of the past three years.
