Speedway Grand Prix are a series of stand-alone speedway events over the course of a season used to determine the Speedway World Champion. As of 2008, all of the events take place in Europe. New Zealand hes been added to the calendar for the 2012 season.
The format for a Speedway Grand Prix changed for the 2007 season onwards. Sixteen riders take part in each Grand Prix and over the course of twenty heats each rider will race against every other rider once. The top eight scorers advance to a semi-final and from each semi-final the 1st and 2nd placed riders will advance to the GP final.
All rides now count towards Grand Prix points totals, including the semi-final and final, which counts double (6-4-2-0) and therefore the maximum points for a single GP is 24 (5x heat wins, semi final win and final win). This scoring revision was introduced as a result of comments made during 2006 that the 4 finalists received too many points compared to the losing semi-finalists who in turn received little benefit compared to, say, the 9th placed non-qualifier. Also, this format means that the winner of each Grand Prix may not be the rider who scores most GP points from each race.
