The 2004 was the third Toyota Racing season in F1, and the team hoped to continue the steady progress with its third car, TF104. But the reality turned out to be far from expectations. Even replacing chief designer Gustav Brunner with Mike Gascoyne in the middle of the year did not save the season for TF104. Gascoyne reworked the car to 104B specification which was introduced at the German Grand Prix. The B version did not change much, and the team freezed any further development to concentrate on the 2005 season car. Toyota drivers at the beginning of the season were Christiano da Matta and Olivier Panis. After German GP da Matta was replaced by another Brazilian, Riccardo Zonta, who spent the 2003 and the majority of the 2004 season as Toyota test driver. Zonta drove in four Grands Prix. In Belgium, he was running in fourth place three laps from the finish when his engine failed. In Suzuka the team hired Jarno Trulli and Zonta had to sit the event out, but the team allowed him to compete in his home race, the Brazilian Grand Prix, which he finished in 13th. It was his last race in Formula 1.
