F1 German Grand Prix: Felipe Massa flips his Williams on the first corner after colliding with Kevin Magnussen

Williams driver Felipe Massa is out of the German Grand Prix after flipping on the first corner of the race.

Massa collided with the McLaren of Kevin Magnussen and flipped over, skidding along the side of the track upside down for a couple of seconds.

Fortunately, the Brazilian was able to walk out of the car and appeared unhurt.

It is the third race this season that Massa has had to retire from. He suffered an unlucky start in Australia, where he was hit by Kamui Kobayashi, and his bad luck continued in Malaysia due to botched team orders.

He was also involved in a collision with Sergio Perez in Canada, though he managed to continue, then at Silverstone last week he was not at fault when Kimi Raikonnen's Ferrari swerved into him.

The stewards reported that the accident was a "racing incident" and no further action will be taken against Magnussen.

Nico Rosberg extended his lead at the top of the Drivers' Championships with a win on home soil, while Mercedes team-mate Lewis Hamilton climbed from 20th to take third.

Massa's Williams team-mate Valterri Bottas finished in second.
