Mercedes wins unofficial 2011 Formula One engine constructors' championship

Sebastian Vettel and Red Bull set nearly all the records and took most of the titles in 2011 but were denied one particular title: For the third successive year (2009-2011), Mercedes secured the most championship points of all the engine manufacturers last season with its three teams (Mercedes GP, McLaren-Mercedes, Force India).

In addition, the six Mercedes cars posted the most race laps and covered the greatest number of race kilometres in the 2011 season (92% of total race kilometres possible). There were only two failures in 330 races for Mercedes engines between 2009 and 2011: Adrian Sutil, Australia 2010, and Michael Schumacher, Monaco 2011.
