There were 10 championship race weekend with one round each, plus a non-championship round at the streets of Shanghai. Originally each track hosted one race each with the exception of Hockenheimring (two races, premier and finale), but when Avignon lost their race EuroSpeedway also hosted two events. Each track hosted one race, with the exception of Hockenheim, which hosted two. As in 2003 each weekend compromised one race of circa one hour and with two compulsory pit stops for each contender.
