Watch German Grand Prix Live Online, Formula 1 Streaming Video

Fans can watch the German Grand Prix live online and see if Nico Rosberg can take advantage of his homecoming to widen the lead in the world championship race.

Rosberg saw his lead over Mercedes teammate Lewis Hamilton drop to just four points following his loss in Great Britain at the British Grand Prix. Rosberg will now get a chance to add more space between his teammate when the race kicks off Sunday at 2 pm local time (12 pm GMT).

Rosberg has already had a big week, signing a new multi-year contract extension with Mercedes early in the week and then marrying girlfriend Vivian Sibold later. Notching his first Formula 1 on home soil would be a fitting end.

"As a German, the heritage of Mercedes-Benz is very special for me," Rosberg said. "It has been a difficult road to get to where we are now – but everybody kept believing and, thanks to the fantastic support from Mercedes-Benz, we are now leading the way in Formula One."

But Rosberg does not just want to give a good showing for his fans at home --- he wants to win the German Grand Prix.

"Hockenheim is a crucial race for all of us. It's the home Grand Prix for Mercedes-Benz and a second home race for me after Monaco, so I'm really focused on getting a top result this weekend," he said.

But fans who watch the German Grand Prix online will likely see Hamilton put up a good showing. He comes into the race after taking care of business on his own home soil, winning the British Grand Prix at Silverstone.

Hamilton said:

Winning at Silverstone was just an incredible feeling–for myself, the team and the fans, I couldn't have asked for more. I feel like I've been on the back foot all year, only briefly leading the championship despite taking the wins I've had, so to have got myself just about level was exactly what I needed - it's almost a fresh start heading into the second half of the season.

I've won twice before in Germany, but not at Hockenheim since way back in 2008. The aim is to change that this weekend.
