BMW Sauber F1.09

The BMW Sauber F1.09 was the Formula One car with which the BMW Sauber team competed in the 2009 Formula One World Championship, launched on 20 January 2009 at the Circuit de Valencia in Spain. It was driven by Poland's Robert Kubica and Germany's Nick Heidfeld, both retained from 2008, and the chassis was designed by Willy Rampf, Walter Riedl, Christoph Zimmermann and Willem Toet, with the powertrain designed by Markus Duesmann. As of 2025 it was the last Formula One car powered by a BMW engine and the last Sauber car to use Petronas fuels, and the last Hinwil-based Formula One car to use other than Ferrari engines until the Audi R26 in the 2026 season. After the team's impressive performance in 2008, which brought its first race win and third place in the championship, much was expected, and BMW made a promising start, with Kubica running second at Melbourne.
