Toyota TF105B

The B version of the TF105 finally debuts in Japan after much testing. The most obvious change is the pick-up points for the front suspension, the lower wishbones now connected to the bottom corner of the chassis (left arrow) rather than to the single keel underneath. This alters the geometry,...

Toyota TF105 - revised front wing

Toyota have adopted very reduced wing elements for Monza because of the high top speeds on this track. Both front and rear wings feature very slim profiles, but especially the front one, with a very narrow flap that features two tiny vertical extensions at the extremities (red arrow).

Toyota TF105 - triple mid wing

In a bid to claw back downforce lost under the 2005 regulations, Toyota adopted this solution in Hungary, where it is so desperately needed. The three wing elements are placed close together to create the effect of a one larger wing on top of the engine cover. Their position in the centre of the car...

Toyota TF105 - front wing flap comparison

Toyota are trying two front wing designs in Germany, featuring flaps with different widths and top-edge shapes. The wider flap (top arrow) extends very close to the central spoon, while the top edge of the narrower one (bottom arrow) descends towards the centre of the wing. The wider version adds...

Toyota TF105 - front wing

This revised design is intended to reduce drag on the fast sections of the Indianapolis Motor Speedway. It features a narrower flap with a diagonal top profile (red arrow), reducing the cross section of the element (and hence drag) as much as possible. Single-lap performance has looked good -...

Toyota TF105 - additional front winglets

To increase downforce at Monaco, extra winglets have been mounted using tiny pillars on top of the main front wing profiles. The concept is similar to Renault's front wing at Imola, but the look is somewhat stranger, closely resembling elements normally atop sidepods. The effect is to add front-end...

Toyota TF105 - new turning vanes

A change for Barcelona right in front of the sidepods. Gone is the single horizontal fin featured since Melbourne. In its place is a double element, with the outer part inclined downwards, and the inner one sporting a deeply-curved upward profile. These elements are part of a continuous development...

Toyota TF105 - new front wing

An evolutionary design for Sepang, sporting a much deeper central spoon profile (red arrow) than its predecessor. The spoon now features a continuous curve, rather than the partially flat section seen before. The extremities of the wing are now slightly higher than the central section, improving the...

Toyota TF105 - additional winglets and profiles

Additional wing profile (1) has been placed on top-front edge of sidepod, similar to that last year on Jordan EJ14. Main purpose is to increase downforce in this area of the car, but also divides airflow coming from the front wing into two, aiding engine cooling slightly. Addition of small winglets...
