BMW Sauber F1.09 unveiled in Valencia
BMW Motorsport Director Mario Theissen reinforces the point: "We have set ourselves the task of further improving our performance relative to the rest of the field. The 1-2 in Canada and a total of eleven podium finishes in 2008 set an exacting standard. In 2009 we are looking to maintain our first-class reliability record while at the same time enhancing our performance levels so that we can be at the front of the pack on a consistent basis. We are aware that we are aiming extremely high. This is the final step in our development, and that's generally the hardest one to take."
2009 also marks the return of treadless tires (slicks) to Formula One. These will deliver increased front-end grip, which makes moving more weight to the nose of the car an attractive proposition. Counteracting this, however, is another new development which the teams have the option of introducing in the upcoming season: KERS (Kinetic Energy Recovery System). The component parts of this technology add extra weight at the rear of the car. Alongside aerodynamics and the optimum use of the slick tires, the integration of KERS represents another key challenge for the engineers. To this end, the front axle has been modified and the rear axle is a new design.
While the chassis is the work of the Hinwil team, the KERS technology has been developed in Munich. There, Markus Duesmann (Head of Powertrain) and his team also have the job of preparing the BMW V8 engine for the extra mileage stipulated in the regulations. Each driver is allocated eight engines for the total of 17 races in 2009.
BMW Sauber F1 Team
The team's race drivers both demonstrated impressive reliability in 2008. Kubica racked up the most points for the team. The Pole added his name to the list of Formula One race winners in Canada, brought home the team's first pole position in Bahrain and also notched up three second places and three third-place finishes during the course of the season. For 2009 he is hoping "that we are as strong at the start of the season as in 2008 and that we can maintain this level of performance up to the final race."
