Although four Bridgestone teams will remain at Jerez on Sunday 11th for a wet tyre test, the general week's work came to a close on December 10th. Of the 10 drivers on track, BMW Sauber's Jacques Villeneuve set the best time of the day, 1:18.752. Tyres and data acquisition on the V8 engine were his focus, including an engine change when the unit reached its mileage.
McLaren once again fielded testers Pedro de la Rosa and Alex Wurz and the pair were second and fifth fastest respectively. De la Rosa continued with the V10 engine and worked on tyres, while Wurz ran the V8 and focused on engine and set up.
"The last two days of testing for me have gone well; only today I covered 500kms with the Mercedes-Benz V8 engine," said Wurz. "We have finished our planned programme on both days and have some positive feedback concerning the overall development programme."
Test driver Ricardo Zonta, third quickest, and Jarno Trulli, fourth, concluded Toyota's programme in the new TF106 with the V8 engine. Tyres were also a focus as the team continues to familiarize itself with the Bridgestone rubber. Zonta will remain at Jerez tomorrow to take part in the wet tyre test.
"Overall, this has been a useful and constructive test," said test team manager Gerd Pfeiffer. "We have had four days of running with four different drivers and it has given us a chance to put some mileage on the TF106 and to spend some time working on set-up with our new Bridgestone tyres."
Tester Marc Gen?, who also stays on tomorrow, was sixth on the time sheet for Ferrari. He continued in the F2004M chassis, working on development of the V8 engine and also tyre development. The Spaniard had a brief on-track stop to cause the only red flag period of the day.
Positions seventh to 10th were filled by a fleet of MF1 Racing pilots as the team tried out some new faces. Fastest of the quartet was Markus Winkelhock, who raced in the Renault World Series in 2005 and previously competed in Formula Renault and F3.
In keeping with MF1 racing under the Russian flag next year, Roman Rusinov was behind the wheel and clocked eighth fastest. The Russian was 2004 Le Mans Endurance GT champion and competed in the FIA-GT series this year. Regular team driver Christijan Albers was ninth overall in the interim chassis with the V8 engine.
In 10th place was Fabrizio del Monte, who previously raced in Euro F3000 and this season lined up in the F3000 Italia series. He also contested two Champ Car races in 2005. Winkelhock, Rusinov and Del Monte all drove the EJ15 V10 car.
"Christijan Albers conducted some tyre testing and some set-up and control systems work," said MF1 chief race and test engineer Dominic Harlow. "We took the opportunity today to evaluate three new drivers in Markus Winkelhock, Fabrizio del Monte and Roman Rusinov. Each of them acquitted themselves very well and really did not put a foot wrong all day."
Ferrari, Toyota, Williams and MF1 will conduct Bridgestone's wet tyre test on Sunday.
