With rain falling throughout the day, the team chose to limit the running with the MP4-22's.
Fernando Alonso had already completed a large amount of kilometres on the Bridgestone Potenza extreme and full wet tyres last week in Valencia, and as a result the team chose to run him only 9 laps in the morning.
Pedro de la Rosa completed a limited programme, working on further understanding the set-up of the car for wet conditions.
Martin Whitmarsh, CEO Team McLaren Mercedes:
"The test this week in Jerez has provided us some valuable data for the team to work on, with two very productive days, which saw the driver's complete significant mileage on the two MP4-22's."
"Unfortunately the last day was hit by rain, which meant that we had to adapt our programme for the conditions. Nevertheless we have a much better understanding of where we are, and more importantly on what work needs to be done between now and Australia to ensure that we arrive in Melbourne in the best possible position."
"Although the timesheets seem to be favouring us we are fully aware of where we need to improve the cars' performance during the forthcoming tests in Barcelona and Bahrain."
Next Test: Barcelona, Monday 12th - Wednesday 14th February
