The F1.08 was launched on January 14, 2008 in Munich. The car was taken out for the first time at the Valencia circuit a day after the launch, where Nick Heidfeld took the car for a brief spin at BMW Welt, the BMW delivery center in Munich. The first track outing of the F1.08 was given to Robert Kubica.

This was the first BMW Sauber to not be designed by Jörg Zander who left the team to go to Honda F1 in January 2008.

For the 2008 season, BMW Sauber kept the white and navy livery used on its cars in 2006 and 2007. However, O2 was replaced by T-Systems, and Cadence Design Systems also became an official equipment supplier. The team continued to be sponsored and supported by Petronas, Intel, Certina, Dell and Credit Suisse.

The FIA implemented a set of rules for the 2008 season that saw all teams use one gearbox for four races and a standard McLaren Electronic Systems ECU that prevents the use of driving aids such as traction control and engine braking.

The sidepod areas underwent massive changes for 2008, along with a cleaning up of the area in front of the rear wing. This made the airflow cleaner and smoother over the car to the rear wing, increasing downforce. The F1.08 also introduced a new front wing that is suspended above the nose. It is similar to the wing introduced on the McLaren MP4-22 in 2007, but it instead has a triple profile. The team also tested 'antlers'; vertical fins on the nosecone of the F1.08 in testing.
