Changes to the technical regulations for the 2005 season have greatly affected the design of the TF105 race car with notable alterations to the aerodynamics. These new regulations have targeted four specific areas on Formula 1 cars – front wing, rear wing, side diffusers and the rear of the car.

A side view comparison of the TF104B with the new TF105

(1) The nose cone is higher to cope with the new regulations of the new wings

(2) The front wing has been raised by 5cm under new aerodynamic regulations

(3) Although quite similar in shape to the TF104B, the TF105 chassis is higher in lower section to the floor and ground (4)

(5) A massive amount of work has been done to reduce the cross-section of the TF105 and the sidepods of the TF105 are considerably lower than those of its TF104B predecessor

(6) Chimneys play a greater aerodynamic role in 2005 and are bigger compared to the TF104B

(7-8) Although rear aerodynamic tools are similar to last year, a lot of detailed work has been undertaken to minimise the loss of downforce imposed by 2005 technical regulations

(9) Exhaust chimney at the rear of the TF105 are greatly reduced in size

(10) Due to the new regulations there is no more seal between the underbody and the tyres

(11) In accordance with new rules, the rear wing needs two top elements pushed forward. They must start from the rear axle. The overhang of the endplate remains the same.
