Toyota TF109 - modified brake ducts

Brakes ducts are increasingly being used as aero devices, as you can see from this outside fin (red arrow) attached to the inner section of the front duct on the TF109. This was seen at the last round in Singapore and retained for Japan.

Toyota TF109 - front wing revisions

The two Toyotas are sporting very different front wings in Italy. Jarno Trulli's TF109 features a revised wing (see main drawing). The endplate features a small vertical fin instead of the twisted fin, which has been on the car since the Monaco race, and which is still present on Timo Glock's at...

Toyota TF109 - additional rear wing profiles

In Hungary Toyota was the only car to have three little 15 cm-wide profiles in the rear wing area. One is attached to the beam wing, another under the main plane, and the third on top of it, as seen previously on the BMW Sauber and Force India.

Toyota TF109 - cockpit strakes

A new feature on the Toyota in Germany was these triangular strakes on the side of the cockpit, immediately ahead of the sidepods. Their purpose is to realign the airflow and reduce the amount of lift on the top of the leading edge of the sidepod. The team also ran a new, Nurburgring-specific, high...

Toyota TF109 - inboard rear brake callipers

As seen in Spain, Toyota are the only team to currently have their rear brake callipers mounted inboard relative to the rear axle, concentrating more weight closer to the car's centre of gravity. Most other teams have the calliper mounted on the other side of the brake disc behind the rear axle,...

Toyota TF109 - 'triple-deck' diffuser

Introduced in Malaysia and retained for China is this triple-deck design. Toyota have added another internal extraction duct (inset - uppermost blue arrows) - which appears to help the airflow to work together with the underside of the lower beam wing - and a kind of turning vane at each end of the...

Toyota TF109 - revised brake ducts

For Sepang, Toyota have introduced this quite sophisticated front brake duct, with a venturi shape to improve the airflow inside the duct and hence improve the cooling of the brakes. Brake specialists Brembo have supplied updated callipers to all six of their customers - BMW Sauber, Brawn GP,...

Toyota TF109 - rear diffuser design

Toyota's diffuser makes a very interesting interpretation of the revised 2009 rules (and one that has already prompted speculation regarding its legality). By exploiting regulations that allow extra bodywork within a 150mm zone in the centre of the car, the team appear to have cleverly shaped the...
