Renault and Spyker MF1 were in action at Silverstone, the second, and final, day of a two day test.

Due to adverse weather conditions, the French team opted to sit out yesterday's session, Nelson Piquet completing a number of laps but not bothering to set a time.

Today, running on the South Circuit, the Brazilian completed over 160 laps in cool, sunny conditions. Piquet worked on engine development, systems and software checks as well as conducting development work for 2007. The French team didn't issue any times.

Meanwhile, the Spyker MF1 Team ran test driver Markus Winkelhock and race driver Christijan Albers as the team completed its two-day test.

"Markus began testing this morning completing 85 laps of the South Circuit," said Dominic Harlow, "and despite initially damp conditions helped the team complete a control systems test and tyre programme before handing the car over to Christijan Albers for the afternoon.

"Christijan covered a similar mileage looking at tyres for the forthcoming season ending Brazilian GP and some development items for 2007. The team were very satisfied with a productive day in good weather conditions and look forward to taking what we have learned to Brazil in the hope of a competitive race."

"Today went quite well," said Winkelhock, "although during the first couple of hours the track was a little damp which changed the test programme. It was good experience as I haven't driven an F1 car in slippery conditions before. There were no problems and we covered a lot of laps, overall I am very satisfied."

"I am really happy with how things went today," added Albers, "it was good to be sitting in the car again and the boys did an excellent job testing tyre compounds for Brazil. I always enjoy visiting the factory when I am at Silverstone as it gives me a chance to discuss our progress with other members of the team."
