were they a manufacturer, they would also get fewer testing miles. However, Mike Gascoyne, the technical director for Renault in 2003, said that not only did Renault save money, they also got more testing mileage out of their cars. Driver changes Fernando Alonso, the team's test driver in 2002, was promoted to a full-time drive at Renault, replacing Jenson Button. Button moved to BAR, where he took the seat vacated by the Toyota-bound Olivier Panis. Panis joined Formula One debutant, and reigning CART champion, Cristiano da Matta at the Japanese team, in an all-new lineup for 2003. Allan McNish, one of the drivers replaced at Toyota, signed with Renault as a test driver, while his teammate from 2002, Mika Salo, left Formula One altogether. Felipe Massa left his Sauber drive to assume the duties of test driver for Ferrari. His place at Sauber was taken by Heinz-Harald Frentzen, who had replaced Massa on a one-off basis for the United States Grand Prix (by which time Frentzen was already confirmed as a Sauber driver for 2003), after having driven for Arrows before the team's collapse. Takuma Sato left the Jordan team to take the place of several others (Anthony Davidson, Darren Manning, Ryo Fukuda and Patrick Lemarié) as the sole test driver for BAR, being replaced by 2002 Formula Nippon champion Ralph Firman. Jaguar replaced both Eddie Irvine and Pedro de la Rosa for 2003. Their new drivers were Mark Webber, who signed from Minardi, and debutant Antônio Pizzonia, who drove in the International Formula 3000 series in 2002 whilst also performing test driver duties for Williams. Webber's vacated seat at Minardi was filled by Justin Wilson, who had won the International Formula 3000 title in 2001. Alex Yoong's Minardi contract from 2002 was not renewed and he moved to the CART series, albeit only for a brief stint, in 2003. He was replaced at Minardi by Jos Verstappen, who had spent a season on the sidelines after losing his Arrows drive to Heinz-Harald Frentzen in 2002. Mid-season changes Minardi's Justin Wilson joined Jaguar from the German Grand Prix onwards, filling in for the under-performing Antônio Pizzonia, who was offered a test driving role at the team but turned it down. He would later resurface as a test driver at Williams. Wilson's seat at Minardi was taken by the Danish driver Nicolas Kiesa, who joined Formula One from the International Formula
