Sauber wound up its 2004 winter testing with Jacques Villeneuve once again at the top of the times, making it all three days of the Jerez test that the Swiss squad was fastest. Felipe Massa was top on Wednesday and Villeneuve the next two days, with his best time of Friday a 1:28.347.
"Jacques and Felipe covered altogether more than 950 kilometres and we didn't experience technical problems which speaks for reliability and consistency," said race engineer Giampaolo Dall'Ara. "Overall I'm happy with what we've done."
The Ferrari test pair of Luca Badoer and Marc Gen? were second and third fastest respectively, Badoer eight tenths down on the Sauber. They continued work on tyres and new components while Andrea Bertolini completed Ferrari's component and electronic programme at Fiorano. His best time was 1:01.633.
Ralf Schumacher was fourth fastest for Toyota at Jerez and was followed on the time sheet by Renault's Giancarlo Fisichella. Test driver Franck Montagny was also at work for the French squad and was 14th. Alex Wurz was sixth quickest and fellow McLaren tester Pedro de la Rosa was 10th.
Takuma Sato was the faster of the quartet of BARs on track, seventh, with team tester Enrique Bernoldi ninth and two youngsters completing their try-outs. James Rossiter clocked 12th fastest and Adam Carroll rounded off the times in 16th. Due to the mixed weather conditions, the team spent most of its time working on tyres.
"The ever-changing weather has caused constant disruption to our programme, however we have been able to get some useful data by running through a series of Michelin wet tyre evaluations," said test team manager Andrew Alsworth. "We are now hoping for much better conditions for next week's five-day test programme."
Christian Klien was eighth quickest for Red Bull Racing and his current driving partner Vitantonio Liuzzi was 13th. The team also had Neel Jani trying out and the Swiss driver, who has been an occasional tester for Sauber, was 15th for his first effort in the blue and silver car. Robert Doornbos was the sole Jordan on duty and was 11th fastest.
