Michael Schumacher continued to set the pace at Barcelona today, as initial preparations for the 2008 season continued.

On his second, and final, day of testing, Schumacher was joined by 2006 teammate Felipe Massa, who posted the fourth best time of the day, albeit 0.555s off the seven-time champion's pace. As on Tuesday, both drivers worked on the development of new components and electronics.

Pedro de la Rosa was second quickest as McLaren continued its programme. The Woking team, which also had Gary Paffett on duty, specifically focussed on running its cars without driver aids.

Heikki Kovalainen continued for Renault, the Finn spending most of the morning doing set-up work in order to evaluate his car's reactions to the various solutions tested. He subsequently worked on brake testing and the new procedures that the team has had to put in place when using the new ECU.

According to the French outfit, it made a lot of headway with its programme despite a minor electrical glitch in the afternoon.

"The day went pretty well," said Kovalainen. "We lost a little bit of track time early afternoon, but it was nothing serious and I reckon we've made good progress. The car ran well and we're going in the right direction. That's what really counts."

"We've made a good step forward today," added Christian Silk. "The mechanics did a really good job to allow us to cover the maximum number of laps. Heikki made good progress. He's found his marks and he feels comfortable in the car, which has proved reliable over the last two days. Tomorrow, we're hoping to take full advantage of our last day here to complete our programme."

Nico Rosberg and Kazuki Nakajima continued to make good progress for Williams. Today, the German out-pacing his Japanese teammate as the duo worked through systems checks and evaluations of the new electronic control units.

David Coulthard and Karun Chandhok worked on similar programmes to yesterday, the main difference being that both men managed to complete significantly more laps, on a track where conditions were not ideal at the start and end of the day, when temperatures were very low.

The Indian driver continued to work on the 2008 electrical systems, while the Scot evaluated various mechanical and aero components aimed at next season. Tomorrow, Coulthard continues testing while Chandhok's cockpit will be taken over by Robert Doornbos, fresh from his Champ Car finale at Mexico City.

Nick Heidfeld and Robert Kubica continued for BMW as the German team once again focused on testing the new standard ECU for 2008. Furthermore, several mechanical parts and other components for 2008 were tested, while the team also evaluated some aero parts. Due to technical problems with some of the new parts the Pole was unable to do as many laps as he wished, however, the team is working hard to rectify the situation for tomorrow.

Sebastian Vettel out-paced Sebastian Bourdais with "German Seb" at the wheel of a car with the 2008 common ECU and "French Seb" driving a car with 2007 electronics, but with traction control and engine braking switched off. However, in the middle of the morning the two men swapped cockpits, primarily so that Bourdais could try the new suspension fitted to Vettel's car.
