The BMW Sauber F1 Team raised the curtain on its 2009 season in Formula One in Valencia this morning. Robert Kubica (24) and Nick Heidfeld (31) unveiled the BMW Sauber F1.09 shortly. Kubica then took the car for its first lap of the southern Spanish circuit.
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. In 2009 we are looking to maintain our reliability record while at the same time enhancing our performance so that we can be at the front of the pack on a consistent basis. This is the final step in our development, and that’s generally the hardest one to take.â€Â
The concept phase for the BMW Sauber F1.09 began back in February 2008. The 2009 car cuts a different figure from all of its predecessors. Its nose is higher and much wider than before. The huge front wing consists of three elements and stretches across the full width of the car. The rear wing, on the other hand, is considerably slimmer – in line with the new regulations – and stands unusually high against the onrushing air. Intricate aerodynamic add-ons, such as air deflectors and cooling air exits, have been reduced to a minimum. Another feature are the sidepods, which are now higher at the front.Â
2009 also marks the return of treadless tyres (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 tyres, 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. The BMW Sauber F1 Team has done early testing with KERS and new aero elements.
