Kazuki Nakajima joined the AT&T Williams team in Jerez, southern Spain, today for day four of this week's five day test. Overcast conditions dominated the weather today, and were met by some fairly strong winds this afternoon.

Despite the less than ideal conditions, Kazuki enjoyed a productive first day out on track. Taking over where Nico left off, Nakajima continued preparing the car for Australia, working through set-up options and mechanical and aero component checks.

Kazuki set a time of 1:21.948 and registered 83 laps of the Spanish track, a total of 367kms.

Sam Michael, Technical Director, Williams F1:

"We spent all day working on set-up, combined with aero and mechanical part testing. In addition, we also carried out some starts testing. Overall, it was a productive day during which we gathered a lot of data. Kazuki was driving today and will finish the week off for us tomorrow."
