Toyota TF106 - revised turning vanes 17 March 2006

The area of the TF105 illustrated is complex and designed to improve the efficiency of the bottom of the car and hence raise downforce. That additional downforce helps to get heat into the tyres more quickly - not a big issue in Malaysian temperatures, but one that is believed to have troubled the team in pre-season testing. There are three main elements (red arrows) - a large, vertical barge board immediately behind the front suspension and then two sculpted turning vanes behind it.
