Brawn GP began the team's on-track preparations for round nine of the 2009 championship, the German Grand Prix, at the Nürburgring circuit located in Germany's Eifel Mountains today. With air temperatures dropping as low as just 10 degrees and a strengthening wind in the afternoon, it was an unseasonably chilly first day of practice.

Light rain just after the start of the morning practice session kept most of the cars in their garages for the first forty minutes. Once out on track, Jenson and Rubens began their initial set-up evaluations, using only the harder of the two tyre compounds provided by Bridgestone for the German Grand Prix weekend, completing 18 laps and 17 laps respectively.

The afternoon session proved equally overcast with a short rain shower ensuring a quiet opening half hour before the team's programme got fully underway. Both drivers focused on an evaluation of the super soft option and the medium prime tyre, in addition to developing the set-up of the car and combating the lack of front end grip suffered in the first session. Jenson completed 32 laps, finishing the day in third position on the timesheets, with Rubens completing 26 laps and in seventh place.

"We made some useful progress today using our experience at previous events where the cold and damp conditions have proved more difficult for us,” said Ross Brawn. “We do still have several areas of the car's performance to develop overnight to ensure that we have the best package for the rest of the weekend. The weather forecast suggests that conditions may be a little more favourable tomorrow, which combined with some work on the set-up overnight, should put us in a good position for qualifying."
