The 2011 FIM Sidecarcross World Championship, the 32nd edition of the competition, started on 3 April and finished after thirteen race weekends on 11 September 2011.

The defending champions were eight time winners Daniël Willemsen from the Netherlands and his passenger Gertie Eggink. In 2011, Willemsen raced with 43-year-old Sven Verbrugge as his passenger, after an injury to first-choice passenger Roman Vasyliaka. Willemsen and Verbrugge were a team for a fifth time in the history of the competition, with the combination winning the 2005 and 2006 titles together.Seitenwagen: Willemsen mit Verbrugge Speedweek, published: 24 March 2011, accessed: 3 April 2011 Willemsen temporarily switched to Ondrej Cermak as his passenger for the first of two German GP's because of an injury to Verbrugge.

Parallel to the riders competition, a manufacturers championship was also held. Like in 2010, the competition was a close contest between 2010 champions WSP and eventual winners VMC.

The Sidecarcross World Championship, first held in 1980 and organised by the Fédération Internationale de Motocyclisme, is an annual competition. All races, manufacturers and the vast majority of riders in the competition being in and from Europe. Sidecarcross is similar to motocross except that the teams consist of two riders, a driver and a passenger. Races are held on the same tracks as solo motocross but the handling of the machines differs as sidecars don't lean. The majority of physical work in the sport is carried out by the passenger, who speeds up the sidecarcross in corners by leaning out. The coordination between the driver and the passenger are therefore of highest importance.The World Championship - Other: What is Sidecarcross.com, accessed: 27 July 2011

Format

Every Grand Prix weekend is split into two races, both held on the same day. This means, the 2011 season with its thirteen Grand Prix has 26 races. Each race lasts for 30 minutes plus two laps. The two races on a weekend actually get combined to determine an overall winner. In case of a tie, the results of the second race as used to determined the winner. While this overall winners receives no extra WC points, they usually are awarded a special trophy. Race start times are set at 13:30 and 16:00.

Events typically consist of a qualifying competition, held in multiple stages on Saturdays of a race weekend while the two race events are typically held on Sundays. One exception to this rule is Easter weekends, when the races are held on Easter Monday. Race weekends can consist of additional motocross or quart support races as well, but the FIM stipulates that the World Championship races have priority. Riders have to be provided with at least one 30 minute free practice season, which will be timed. A race can consist of up to 30 starters and the qualifying modus is dependent on the number of entries. Up to 32 entries, it will be held in one group split into two sessions of 30 minutes each. Above 32 entries, the starter field will be sub-divided into two groups through ballot and the current standings. Each qualifying group can consist of up to 30 racers. Should there be more than 60 entries, a pre-qualifying has to be held. Of the riders in the two groups, the top-twelve directly qualify for the races. The remaining teams then go to a second-chance qualifying, in which the best six advance. The riders placed seventh and eighth remain in reserve should one of the qualified teams not be able to participate.FIM SIDECAR MOTOCROSS WORLD CHAMPIONSHIP APPENDIX FIM website, accessed: 27 July 2011
