As usual on a Friday, the BMW Sauber F1 Team used both free practice sessions for race preparation. For the first time the kinetic energy recovery system was not only used on Nick Heidfeld's car, but also on the F1.09 of Robert Kubica. Both 90 minute sessions went without any technical failures. Robert Kubica:
BMW Sauber F1.09-05 / BMW P86/9 (KERS)"We completed our standard Friday programme and tried to learn more about the nature of the track and to understand the tyre compounds. While the option tyres are quite fragile, it is difficult to make the prime tyre work. Additionally, this was the first time I was running KERS at a Grand Prix weekend. There were a lot of tests to do. Now we have to check and evaluate the data."
1. Training: 18th, 1:38.463 min / 2. Training: 17th, 1:37.491 min
BMW Sauber F1.09-04 / BMW P86/9 (KERS)"As is normal for us on Fridays we focused on tyre evaluation for the race. They do not really work as we would like them to. We now have to try to improve the balance of the car."
1. Training: 16th, 1:38.456 min / 2. Training: 18th, 1:37.544 min
