Red Bull Racing returned to have a great season in 2010, thanks to their hiring of designer Adrian Newey in 2007. They won the Constructors' Championship in the penultimate round in Brazil, and Red Bull driver Sebastian Vettel won the championship in the final round of the 2010 season at Abu Dhabi. Mercedes GP (formerly Brawn GP) had a much less successful and winless season than 2009 with their two new drivers – seven-time World Champion Michael Schumacher had returned to Formula One, but was regularly beaten by fellow German, Nico Rosberg. McLaren and Ferrari had better seasons in 2010, finishing respectively second and third among the constructors. The Drivers' Championship was very closely fought, with six drivers leading the championship at various points, in the joint longest ever (nineteen-race) season. For most of the season, the title looked like it could have gone to either Red Bull's Sebastian Vettel or Mark Webber, or either McLaren's Lewis Hamilton or reigning World Champion Jenson Button (also at McLaren). But, the Ferrari of Fernando Alonso clawed back 47 points after the British Grand Prix, to be leading the Drivers' Championship with two races left. A record four drivers were still in contention for the title going into the final round in Abu Dhabi. They were Alonso, Webber, Vettel and Hamilton (placing in that order in number of points before the race). They did not finish that way though, with Vettel winning the race and the title when the others finished too far down the field. Vettel became the youngest ever World Champion in the history of the sport.
