Toyota TF109 - 'triple-deck' diffuser 18 April 2009

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 diffuser (red arrow). Together, these changes should boost the efficiency of the main double-decker part of the diffuser, increasing the levels of downforce produced.
