After the disaster of the Brazilian Grand Prix the BMW WilliamsF1 team was back to work testing at the Jerez circuit preparing for the final rounds of the 2005 Formula One season, the Japanese and Chinese Grands Prix.

Present for the days testing was Mark Webber, test driver Nico Rosberg and 2004 Formula BMW ADAC Champion Sebastian Vettel. The test was conducted in sunny conditions. The test will run for two days and will be the last for the 2005 season.

The only team present at the circuit was the BMW WilliamsF1 team. The three drivers would work through various programmes. For Mark these would focus on tyre evaluations and set-up work. Nico would work on testing of the brakes, including the testing of various braking materials. He was also involved in tyre testing. For Sebastian his time in the car was spent simply getting used to the demands and complexities of a F1 car.

Mark completed 125 laps, with a best lap 1m:17.917. Nico covered 37 laps with a best of 1m:19.265. Sebastian Vettel completed 25 laps, with a best time of 1:21.364 minutes.

Vettel spoke of his experience in a F1 car. He said: "It was an unbelievable experience! The brakes, the g-forces and the power of the engine are beyond description. Thanks to BMW and WilliamsF1 for giving me this chance to test. The test team looked after me brilliantly and I learnt plenty."

BMW Motorsport Director Mario Theissen added: "Sebastian made a successful switch from around 220 bhp in Formula 3 to almost four times that in a Formula One car. The whole team was pleased with him. He now has a first-hand idea of the extreme dynamics involved and the physical demands on the driver. That experience will stand him in good stead in the future."

WilliamsF1 Test Team Manager Tim Newton commented on the days testing. He said: "On our first day at Jerez, the drivers managed to complete a substantial amount of mileage, in particular Mark, who recorded over 500kms while tyre testing for Michelin. Nico was also on duty and covered 37 laps of tyre work before his half day session was ended prematurely by a technical problem. Nico is now on his way to Bahrain for the final round of the GP2 Championship. With a three point lead in the Drivers’ rankings, the team would like to wish him
all the best for a successful weekend."
