The Toyota TF104 was a car designed by Toyota Racing for the 2004 Formula One season. It was driven by Cristiano da Matta and Olivier Panis at the start of the season. Midway through the season, two other drivers, Ricardo Zonta (the team's test driver) and Jarno Trulli, drove for the team. A B-spec version of the car was introduced at the German Grand Prix. Despite the race drivers using the B-spec version of the car, the third driver of the team used the A-spec version of the car.
