It's been inevitable for much of the season but Mercedes finally sealed the constructors' championship at the Japanese Grand Prix following Nico Rosberg's Suzuka win. The team needed just eight points to put them out of reach of second placed Red Bull, and Rosberg's victory coupled with Lewis Hamilton's third placed ensured the Silver Arrows comfortably retained the title. It's the third straight year that Mercedes have won the championship with the successes in 2014 and 2015 just as dominant as their latest triumph.
