Toyota TF105B 08 October 2005

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, bringing the wishbones closer together (yellow line), improving the dynamic behaviour of the car's front end. The higher position of the lower wishbone also allows a cleaner path for airflow coming from under the front wing, improving the aero efficiency of the small turning vanes at front-axle level (right arrow).
