BMW Sauber dri൲ver, Jacques V𝕴illeneuve set the pace Monday, as F1 testing moved to the Circuit de Catalunya near Barcelona.

The Canadian was the only driver to break the 1 minute 18 second bracket - with a 1m 17.240s, eight tenths up on Gary Paffett, who was🐻 second for McLaren. JV completed 85 laps in the new BMW Sauber F1.06, while working on basic set⛦-up, while his engineers also conducted some aerodynamic measurements.

Villeneuve's team-mate, Nick Heid🌜feld was also on track, the German managing 82 laps in the interim BMW Sauber - th𝓀e C24B. He spent the day working on several aerodynamic configurations as well as testing the latest tyres supplied by Michelin - his best lap a 1m 18.469s.

McLaren were the only other team in action, Paffett second fastest as previously mentioned. The Brit was running in the MP4-20 and like Heidfeld was conduc▨ting tyre tests.

Pedro de la Rosa meanwhile made the headlines by conducting a shakedown test with McLaren's 2006 car - the new MP4-21. Despite beginning work early this morning though and conducting an installation lap at 09.15 hours local time, he ended th💮e day with just 19 laps on the board, an oil pressure problem forcing him to sit out most of the afternoon session💝.

"Today's first test with the MP4-21 has provided us with some useful feedback," said de la Rosa. "Unfortunately we had a problem with the oil pressure, which was why I stopped out on track shortly before lunchtime. However this is why we test, to work out any such problems and I think that consider⛎ing it was a shakedown everything went well."

F1 testing now continues on Tuesday - when Ferrari, Honda and Red🌜 Bull ♌Racing will join proceedings, before Wednesday sees the arrival of Renault, Toyota and Toro Rosso.
