Development
The TF103 was quite a conservative design, by the team's admission it was more of a 'logical evolution' from its predecessor the TF102. Lighter and with more downforce, the car was a joint effort between Gustav Brunner's design team and Keizo Takahashi, chief of Technical co-ordination.
The biggest improvement over the TF102 came with the engine, the RVX-03 had been tested for the first time in September 2002 and offered the team benefits twofold over the RVX-02; it was lighter, and provided more power. The engine was the brainchild of Italian designer Luca Marmorini.[4]
Performance
The TF103 stepped up a level in terms of performance too, with the car scoring a total of sixteen points between its drivers, da Matta outscoring Panis 10–6. Perhaps the most notable race involving the TF103 was at Silverstone for the British Grand Prix when both cars ran 1-2 for a time amidst the confusion brought about by a track invader on the 11th lap.[5]
In the constructors' standings, Toyota finished in eighth.[6]
