Both Antonio and Nick focused on evaluating setups for the wet conditions. Nick would complete ninety six laps, with a best time of 1m:22.490 to be second fastest on the day.  Antonio would complete forty nine laps, with a best time of 1m:23.365.

Over the three days of testing Webber, Pizzonia and Heidfeld would complete a total of 506 laps of the Jerez circuit, a distance of 2,241 kilometers.

WilliamsF1 Test Team Manager Tim Newton commented on the test session: "After a rather troublesome test in Barcelona last week, we’ve made good progress this week in Jerez. Mark, Antonio and Nick all did a good job with the interim cars and, despite some rather inclement weather, all three recorded impressive mileage.

On his fist outing with the team, Nick settled in well and gave us some productive feedback. Credit must be given to everyone, both at the factory and at the track, who have worked hard over the past week to rectify the teething problems encountered in Barcelona. As a result, we’ve had a relatively trouble-free, and therefore productive, test.”

For Nick Heidfeld the two days of testing he had was not carried out under the best of conditions but he did come away happy with the time he had in the car.

He said: “I’m really happy with the two days I’ve had in the car. It’s a very nice car to drive, and I was getting more familiar with it lap by lap. I think I would have benefited from some more time, and better weather to get a proper feel of how the car handles in the dry. Overall though, it’s been a very productive and satisfying test.”

As for his chances of securing a full time drive with the team Heidfeld had these comments to the German RTL television network: "I have a good feeling and think I have a good chance. I've done all I can and I hope it's enough. I must now wait and see what happens."

The team will be back in action at Jerez from Wednesday 8th December, in the teams last test for the year.
