With the wet and slippery conditions the team would take the opportunity to test some of Michelin's wet weather tyres, including a shallow grooved wet tyre. Once the conditions improved the team would test four different dry weather tyres types.

Ralf would complete eighty two laps and set the fastest time, a lap of 1m:20.393. For Marc he would complete forty one laps, his fastest lap been a time of 1m:20.941.

The only problem of the day was when Marc was to crash his car against the tyre barriers causing damage to the front of his car, which his mechanics were able to repair to allow Marc to return to testing. The team will continue testing on Thursday

Tim Newton, WilliamsF1 Test Team Manager, had the following comments regarding the days test: "Ralf and Marc undertook testing responsibilities at Jerez circuit today with both drivers concentrating on set up work of the FW25 and tyre testing for the final race of the season at Suzuka.

With heavy downpours continuing until lunchtime, we managed to carry out some useful wet weather running this morning as well as getting some dry laps in this afternoon.

Ralf completed a comprehensive 63 laps and recorded the fastest time with a 1:21.230m, while Marc ran for 13 laps and ended the session with a best time of 1:23.350m.“
