Ferrari 248 F1 - diffuser 30 June 2006
For Indy, the diffuser's side walls have been dramatically revised. Gone is the knife-edge profile at the base of the central section and in its place is a small, upward-curving lip. The diffuser is no longer parallel with the ground over its entire length. Instead it bends upwards, reducing the impact of the airflow with the sides of the main channel. This increases air extraction from the bottom of the car, improving the stability of its rear end.
