F3 Euro Series man Daniel Clos meanwhile ran for Williams, notching up 75 tours, his quickest a 1m 23.224s. It was his first ever run in an F1 car.

"After successful preliminary tests of the KERS flywheel today, the team will be undertaking more component testing tomorrow, part of which will include 2009 aero parts and rear wing," said Williams technical director, Sam Michael.

Mike Conway was the only other runner on track. However, he only did 20 laps for Honda.

"We are testing in Jerez next week for four days," said Honda team principal, Ross Brawn on Sunday following the Italian GP, "but the focus there will be on projects for the 2009 car and in particular the KERS system [rather than the final long haul races]."

Testing now continues tomorrow with a further five teams due to join the fold, namely McLaren, Renault, Toyota, Red Bull Racing and Toro Rosso.
