Clear skies and calm winds gave Formula One teams testing at Bahrain International Circuit fine conditions Monday, and BMW Sauber, Ferrari and Toyota responded with lots of laps in preparing for a season six weeks away. Teams needed to make up for two days of last week's test lost to sandstorms. Air temperatures Monday ranged to 80 degrees Fahrenheit and track temps to above 90 in the Arabian Gulf sun.

Jarno Trulli put 141 laps on the Toyota TF109. Christian Klien piled 131 laps on the BMW Sauber F1.09. Kimi Raikkonen drove the Ferrari F60 to 116 laps.

Klien claimed fast-lap honors with a tour of 1 minute, 32.544 seconds on the 3.3-mile course. Raikkonen followed with a 1:32.804, and Trulli timed a 1:33.064.

Klein worked on mechanical and aerodynamical setups, compared tire compounds, and simulated starts. "Today was a very productive day," Klien said. "We collected a lot of data, and I even did a long run at the end of the session. Again, we didn't have a single technical problem, which is very encouraging."

Raikkonen also worked on setup assessment and tire comparisons. He made long runs in pursuit of reliability and worked on practice starts.

Also working on setup evaluations and tire comparisons, Trulli ran enough laps to complete two race distances. "I think this is my personal best for mileage at a test day," he said. "This has been a good start to our second week here."

Raikkonen and Trulli return to their respective cockpits Tuesday, while Klien hands off the BMW Sauber to Nick Heidfeld.
