The BMW Sauber were unable to complete their programme during the first day of testing at the Valencia circuit due to poor weather conditions at the Spanish track.
The German squad decided to save testing mileage and instead had Nick Heidfeld and Robert Kubica carrying out system checks, collecting data on wet and extreme wet weather tyres. The team also practiced pitstops.
Kubica covered a total of six laps, with Heidfeld covering 22. No times were issued.
BMW continue testing alone at Valencia tomorrow.
