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 count towards Grand Prix points totals, including the semi-final and final, the maximum points for a single GP is 21 (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.
The 15 permanent Grand Prix riders have been decided by various methods over the history of the series. For the 2015 season, the top 8 riders from the 2014 World Championship automatically qualified. They were joined by 3 riders who qualified via the Grand Prix Qualifiers, and 4 riders who were nominated by the series promoters, IMG.
The Speedway Grand Prix series and the Speedway World Cup were originally promoted by Benfield Sports International, which later was renamed to BSI Speedway. On 11 April 2007 it was announced that BSI Speedway had been acquired by IMG and the existing team shall take up roles within IMG.
