Baku, October 26, AZERTAC
Mercedes' Lewis Hamilton won his third Formula 1 World Championship to become only the second British driver after Sir Jackie Stewart to achieve the feat.
Hamilton, 30, won a thrilling United States Grand Prix to seal the drivers' title with his 10th victory of 2015.
He pressured team-mate Nico Rosberg into a mistake during a frantic last 10 laps after a safety car and swept by.
It was an exciting climax to a race of fluctuating fortunes, lead changes and superb racing in changing conditions.
Ferrari's Sebastian Vettel could have kept the race open until Mexico next weekend had he finished second, but could manage only third place behind Rosberg.
