After the team's impressive performance in 2008, winning their first race and coming third in the championship, much was expected of them. BMW made a promising start to the season, with Kubica running second at Melbourne and lapping faster than the leader before retiring in a collision, and Heidfeld finishing second at the chaotic Malaysian GP. However, the F1.09 ultimately proved to be disappointing. At times, the drivers could barely scrape through to Q2, let alone challenge for pole. Both drivers expressed discontent with the slow developments to the car. Towards the end of the season things began to look up, with the cars managing fourth and fifth at Spa-Francorchamps and Kubica finishing second at Brazil. However, the damage had been done, and BMW announced that 2009 would be their last season in Formula One. The team eventually finished sixth in the Constructors' Championship.
