Abu Dhabi - Nico Rosberg ended his 2015 season in triumph on Sunday when he completed a hat-trick of victories in the Abu Dhabi Grand Prix ahead of his Mercedes team-mate and world champion Lewis Hamilton.
The 30-year-old German, who has produced remarkable dominant form since seeing Hamilton secure his third drivers' title at last month's United States Grand Prix, made a perfect start from his sixth successive pole position and, pit-stops apart, was in control all the way.
Rosberg was celebrating his sixth win of the year and the 14th of his career. It was his first success at the Yas Marina circuit where Hamilton beat him in 2014 to take his second title.
Hamilton won 10 races this year, but on Sunday was unable to rediscover the form that carried him to the championship despite pushing hard through the middle and latter stages of the race.
Finn Kimi Raikkonen finished third ahead of his Ferrari team-mate, four-time former champion Sebastian Vettel and Sergio Perez of Force India.
Daniel Ricciardo was sixth for Red Bull ahead of Nico Hulkenberg in the second Force India, Felipe Massa of Williams, Romain Grosjean who marked his last race for Lotus with a surge to ninth and Daniil Kvyat in the second Red Bull.
