Mark Webber and Nick Heidfeld have successfully concluded the BMW WilliamsF1 Team's four-day test programme at Jerez. With conditions being once again ideal (20°C), the two drivers were able to complete an impressive total of 244 laps.

Nick focussed on tyre evaluations with Michelin, the BMW WilliamsF1 Team's tyre partner. The fastest of his 131 laps was clocked at 1:17.875 minutes. Mark was busy running a race simulation. In addition, the Australian worked on the set-up of his Williams BMW FW27. He did 113 laps, setting a personal best time of 1:17.350 minutes. Jenson Button (B•A•R Honda) was the fastest driver of the session, posting a 1:15.662.

Tim Newton (Test Team Manager, WilliamsF1): "We’ve been in Jerez again this week with both Mark and Nick running in the FW27s. Throughout the week, the drivers concentrated on set-up evaluations as well as tyre testing with our partner, Michelin. The car has proved particularly reliable over the four days, allowing both drivers to clock up an impressive total of 3,259kms. This has provided us with invaluable data to work with in the weeks leading up to Melbourne."

Mario Theissen (BMW Motorsport Director): "We had a successful test in Jerez this week having covered over 3,000kms and completed a full schedule, including a race simulation. On the engine side, we worked on perfecting starts and traction control. The main focus of the test, however, was on car set-up and tyre testing. We will be selecting the engine specification for Melbourne from the information we gathered this week."
