Panasonic Toyota Racing mounts the challenge with TF104 Panasonic. Toyota Racing has used a media open day at its Cologne headquarters as an opportunity to unveil its 2004 race car, the TF104. Designed by Chief Designer Gustav Brunner and his team, the TF104 is an evolutionary redesign of its TF103 predecessor and will play an integral role in the team's aim of closing the gap to Formula 1's leading teams in 2004. Underneath the evolutionary bodywork, the car's internal components have undergone a significant reassessment and redesign that the team is confident will reap rewards in the long term.
