FIA President Max Mosley announced dramatic rule changes for the 2009 season in a bid to improve the spectacle of the sport, with the cars undergoing major changes in an effort to increase overtaking. The design changes significantly altered the design of the cars, incorporating wider and lower front wings, taller and narrower rear wings, and a reduction on aerodynamic bodywork. Also introduced were slick tyres and Kinetic Energy Recovery Systems, as well as implementing cost-cutting measures in a response to the rising costs of competing.
