Felipe Massa set the pace again today for Ferrari as the first F1 test of the season continued at Valencia in Spain.
Massa completed 124 tours in total, the most of anyone runner, spending the day concentrating on development work with the new Ferrari F10 and on analysing tyre behaviour. His best lap was a 1 minute 11.722 seconds and that left him around three tenths up on his closest rival.
Kamui Kobayashi was second and 'best of the rest' on his debut at the wheel of the Ferrari-powered Sauber C29: "It was definitely a good day," Kobayashi reflected. "We had no problems with the car and covered a lot of mileage.
"The car felt good. I enjoyed driving a lot and also working with the team. It was a difficult winter for everyone but they seem to have done a good job; I want to thank them for that. Now it is important to keep working hard for the remaining test opportunities."
Lewis Hamilton meanwhile got his first taste of the new McLaren-Mercedes MP4-25 and according to the team enjoyed a 'very busy and productive day' of running ending proceedings in third.
He continued with the programme started by test and reserve driver Gary Paffett on Monday, working on car set-up and understanding the difference in balance caused by the heavier fuel-loads and narrower 2010-spec front tyres. Hamilton declared himself happy with the car's performance and reliability and will hand the machine over to reigning world champion Jenson Button for day three.
"It's a different feeling compared to the first lap of the first test day of 2009," Hamilton told BBC Sport
. "It's a positive feeling. I've kept a close eye on the development of this car. I've seen it evolve and had input into it which is very exciting. I got out smiling. The problems I had [last year] I don't have in this car."
Robert Kubica was next up in fourth for Renault and a lot closer to the pace having propped up the times on Monday. He did 119 laps in total and was happier with the R30, despite bringing out the red flags at the close of the session when he stopped on the start-finish straight.
"After checking the systems on the car yesterday, we spent today trying to understand the car a bit more, especially to see how the balance reacted to some set-up changes," Kubica explained. "It's quite different to what I have been used to, so it was important to get a good feel for how the car behaves. We did one very long run, which went pretty well, and there have been no problems, which is a good sign for our reliability."
"Another good day. We did a lot of laps: 119 in total, so we're pleased with our reliability," added Renault's chief race engineer, Alan Permane. "The changes we made overnight have cured some of the understeer and Robert seems much happier and is feeling more comfortable with the car now. The track conditions were reasonably good and the Bridgestone tyres are particularly well suited to the circuit and are easy to test with."
