Da Matta completed his move up the racing ladder in 2003, reaching the pinnacle of motor sport with the Toyota Formula One team. He scored 10 championship points that year, four more than seasoned veteran and teammate Olivier Panis, and soon made a name for himself in Formula One when he spent much of the first half of the 2003 Brazilian Grand Prix hounding reigning World Champion Michael Schumacher in the monsoon-hit race before ultimately finishing tenth. He led the 2003 British Grand Prix for seventeen laps after the race was disrupted by a protester who invaded the track and triggered the deployment of the Safety Car. This caused most of the front-running cars to make unscheduled pit stops leaving Da Matta in the lead, ultimately finishing seventh for one of four points-scoring finishes in his debut season. His fortunes took a downturn in 2004, however. Having scored only 3 championship points, da Matta lost his race seat to Ricardo Zonta after the German Grand Prix in Hockenheim. This was not only due to performance issues, but also due to Da Matta openly making statements about how uncompetitive the Toyota was.
