( CNN ) -- Nico Rosberg capped a memorable week by winning the German Grand Prix at Hockenheim but Sunday 's race will also be remembered for a frightening opening lap incident involving the unfortunate Felipe Massa . The veteran Brazilian was clipped from behind by McLaren 's Kevin Magnussen and his Williams performed a spectacular somersault before ending in the safety gravel at Hockenheim . There were immediate fears for his safety but soon allayed by the Twitter account of his team . `` Big crash for Felipe but he is out the car and heading back to the garage , '' it said . It was the second race in a row in which the 33-year-old Massa has been the victim of a first lap incident , his hopes at the British Grand Prix ended when Kimi Raikkonen of Ferrari careered off . Earlier in the season , Massa was also involved in a 300 kph collision at the Canadian Grand Prix , accusing rival driver Sergio Perez of being `` dangerous '' as they battled for fourth and both ended in the barriers . The safety car was immediately deployed but on the resumption Rosberg , who had been on pole , took command and drove untroubled to take the checkered flag for his seventh career F1 victory . Since retiring while in the lead at Silverstone , Rosberg has married his long-time girlfriend Vivian Sibold , signed a contract extension at Mercedes and seen his beloved German football team win the World Cup . The victory extended his title lead over teammate Lewis Hamilton to 14 points . `` It 's fantastic , '' he said in the post race interviews . `` It 's an amazing feeling to win at home . It 's a very special day . '' Britain 's Hamilton had the rub of the green in his home grand prix , but his luck deserted him this weekend , crashing out in qualifying with a brake problem . It led to a change of brake disc and a five-place grid penalty so starting from 20th . He cut a swathe through the field and initially looked to be on a two-stop strategy which may have given him the opportunity to challenge Rosberg . His second stop came on lap 32 of 67 , but he pitted for a third time just seven laps later after Adrian Sutil spun his Sauber and was left stranded in the middle of the track . Race stewards decided not to put the safety car out out for the second time and at this point Hamilton 's engineers pulled him in for a third stop . He still looked set to overtake Massa 's teammate Valtteri Bottas for second , but the Finn drove superbly to hold him off in the closing stages . Reigning four-time champion Sebastian Vettel got the better of great rival Fernando Alonso of Ferrari for fourth place . Vettel 's Red Bull teammate Daniel Ricciardo of Australia took sixth .
