Lewis took over from Jenson today, continuing the development work his team-mate began yesterday: refining set-up and evaluating tyres.
The morning was spent conducting shorter runs, attempting more experimental set-ups -- changes that Lewis found beneficial to the car's balance.
The different set-up changes caused several lengthy turnarounds in the morning before Lewis could concentrate on a single long-distance run in the afternoon -- which was punctuated by several late red-flag periods.
Jenson is back in the car tomorrow, conducting further fine-tuning of MP4-25.
Driver for day three - Jenson Button
Duration of test - Four days (February 25-28)
