Sauber
Several upgrades were scheduled for Turkey, including an improved energy recovery braking system (KERS) and a new air diffuser to improve downforce and traction. While the new diffuser was installed, the KERS would not fit the new car and both drivers raced without the device. BMW had been one of the strongest supports of KERS. After the British Grand Prix, the team announced they would stop development KERS. They set their focus on improving the car's aerodynamics (how well the car moves through the air). This left Ferrari and McLaren as the only remaining users of the KERS system. In the European Grand Prix at Valencia Robert Kubica scored the team's first points since the race in Turkey.
