3. Similar ones on the TF104, combined with new horizontal fins in front of the side pods.

4. Shorter side pods to improve aero efficiency with bodywork further away from the front axle.

5. Longer and thinner fuel tank.

6. TF104 keeps the same style exit for hot air introduced on TF103 at Silverstone 2003.

7-8 Different winglet evolution of the ones introduced on TF103B intermediary car.

9. To improve aero efficiency and rear visibility the chimneys have been moved backwards and inwards.

10. On TF103, the hot air was originally coming out on top in front of the rear tyres. On TF104, the shape at the back of the car is deeper to improve the airflow to the rear wing. All mechanical components are reduced in size and weight.

11. Due to new rules, end plates are 10cm bigger with the wing profiles at the same overhang to the rear axle (50 cm).
