Massa leads the way at Jerez

The Brazilian driver, who yesterday was forced to miss the session after feeling unwell, returned to the cockpit of the Ferrari F2007 and emerged on top of the times with a best lap of 1:19.746.

Massa beat teammate Kimi Raikkonen by three tenths of a second after the Finn lost a big part of his day due to a mechanical problem and then poor weather, with rain hitting the track in the afternoon.

McLaren's Lewis Hamilton was second quickest, with teammate Fernando Alonso, who joined the test today, finishing as fourth fastest behind the BMW Sauber of Robert Kubica.

World champion Alonso did not enjoy a trouble-free day, going off track in the morning with an apparent mechanical problem and then stopping at the end of the straight in the afternoon.

Raikkonen, Red Bull's Mark Webber and Ralf Schumacher in the Toyota caused the remaining red flags of the day, all of them when their cars stopped on track.

The Renault team had their two test drivers again in action at Jerez. Nelsinho Piquet was the faster of the two, outpacing teammate Ricardo Zonta by seven tenths of a second. Zonta got his first taste of the new R27 car yesterday.

Williams drivers Alex Wurz and Nico Rosberg completed their second day of work with the new FW29 unveiled last week. The duo had another productive session, also setting promising times in the Toyota-powered car.

Honda's Jenson Button was joined by IRL driver Marco Andretti, who got his second taste of F1 machinery, testing the new RA106. The American driver managed 74 laps and finished at the bottom of the times.
