Williams Jerez test notes day four

Rubens Barrichello completed the team's fourth day of testing at Jerez today. Despite rain upon arrival at the track this morning, the 4.428km circuit soon dried out and made way for some valuable dry running in the afternoon. The team continued their 2010 season preparations with further set-up work on the FW32.

Rubens set the third fastest time of the day with a 1:20.341 behind Hamilton's McLaren and Sutil's Force India, and completed 90 laps of the Spanish track before a gearbox issue forced him into the garage at approximately 4pm this afternoon.

The team will now stay out in Jerez to prepare for next week's four day test which commences on Wednesday when Rubens will once again take to the cockpit.

After a damp start to the day, we went through some set-up work with Rubens during the afternoon run and made good progress understanding the car. We also worked on systems in the background. Unfortunately, we had to stop earlier than planned due to an issue with the gearbox. The parts were quite high mileage, so we are understanding where those limits are now. Overall, the test has been quite useful for putting mileage on the car, sorting out reliability issues and making progress on set-up.

Rubens Barrichello
We concentrated on set-ups today and completed 90 laps before we had the problem which the team are investigating now. The car has performed well these past two days and we've discovered some interesting things which will help us move it forward. I was hoping to go for a performance run at the end of the day because the car felt good, but unfortunately my session was cut short. There's work to do in terms of improving performance, but I'm happy with the results that are coming out.
