Ferrari 248 F1 - rear diffuser 28 February 2006

The 2006 Ferrari sports a particularly complex diffuser design. The central section is divided in two: the upper part (1) deals with the air passing immediately over the diffuser and that coming from inside the sidepods, the combination of the two increasing airflow speed. The lower part (2) improves underbody air extraction, with its steep upward angle. Either side of the central section is a new, additional channel (3), while the main side channels are divided into two sub sections by means of a single vertical fence (4). Near the inner wall of the rear tyres, a series of steps (5) in the diffuser's profile help to extract the turbulent air generated by the wheels, minimising its disruption of the main airflow passing under the diffuser's side sections.
