The Fédération Internationale de l'Automobile (FIA) had planned to introduce a budget cap, in order to safeguard the sport and reduce the costs. The proposal had an optional budget cap of €30 million ($45 million, £27 million), with greater technical and design freedoms allowed to teams who nominated to use it. The teams objected to what they believed would be a two-tier championship and five of the teams within the Formula One Teams Association (FOTA), Ferrari, BMW Sauber, Renault, Red Bull Racing and Toro Rosso announced their intentions to withdraw from the 2010 championship. BMW Sauber later announced on their withdrawal from Formula One at the end of the 2009 season.
