ABU DHABI (Reuters) - Britain's Lewis Hamilton became Formula One world champion for the second time after winning the season-ending Abu Dhabi Grand Prix for Mercedes on Sunday.

It was the 11th win in 19 races for the 29-year-old, who took his first title with McLaren in 2008 and becomes Britain's first multiple champion since Jackie Stewart in 1971.

Team-mate and sole title rival Nico Rosberg finished 14th after starting on pole position but losing out to Hamilton at the start and suffering a loss of engine power from the 25th of 55 laps.

Brazilian Felipe Massa finished second for Williams in the race, with Finnish team mate Valtteri Bottas third.
