Building the new car represented a massive challenge. Fundamental changes to the regulations have, in many cases, consigned the fruits of experience to the dustbin. Development work on what is a radically different race car got underway even earlier than usual. Indeed, the concept phase for the BMW Sauber F1.09 began back in February 2008. The 2009 car cuts a very 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 eye-catching feature are the sidepods, which are now higher at the front.
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.
Willy Rampf is responsible for the F1.09 concept and will oversee operations at the race track in his capacity as Technical Coordinator. Managing Director of BMW Sauber AG Walter Riedl will lead the technical department at Hinwil in Switzerland and has responsibility for the development of the car.
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.
It may be all-change in terms of the engineering behind the car, but the men behind the wheel will be the same as in 2008. The BMW Sauber F1 Team will once again line up on the grid with the Pole Robert Kubica and German Nick Heidfeld as its driver pairing. And 26-year-old Austrian Christian Klien also stays with the team as test and reserve driver.
