SuperGP race meeting, was cancelled five days before practice was due to begin. With cars and series infrastructure still tied up in London and no comment forthcoming from A1GP, organisers in Australia were forced to announce the series would not appear at what had been a high-profile addition to the A1 Grand Prix calendar. The event was underwritten by the Queensland state government, who mentioned the possibility of taking legal recourse against A1 Grand Prix. The series was thrown into further doubt as more races were cancelled, with an announcement made on 5 November 2009 stating that the races in China and Malaysia would not be taking place. The last race that was to be held in the season, the Dutch round, was switched for Superleague Formula. This put an end to the hopes the season would start and also put the future of the series in doubt. Champions Teams Each A1 Grand Prix team represented a nation. Drivers must have the same nationality as the team they drove for. The team car should also represent the country. The team owner, principal and crew, however, did not need to have the same nationality as the team. Twenty-nine nations started one race in A1GP – as in the table below: Drivers Race weekend A1 Grands Prix of Nations took place over a three-day period, from Friday to Sunday. The teams were given five sets of dry weather slick tires, and two sets of wet weather treaded tires per weekend. However, if the weather was extreme, the team could be given more wet weather tires at the expense of the slick tires. The race weekend started with two one-hour practice sessions held on the Friday, and then another on the Saturday morning. A two-hour qualifying session took place on Saturday afternoon, and two races took place on Sunday. Primarily, the three practice sessions were for car setup and track familiarisation before the official competition began with Saturday qualifying. Three different drivers could participate in the three practice sessions; the driver elected for qualifying or for one of the races was required to have taken part in at least one such practice session. Qualifying A1 Grand Prix used a unique qualifying format, which began at 14:00 local time on the Saturday of the race weekend, to determine the grid lineup for Sunday's races, the Sprint Race and the Main Race.
