2012 rule changes - revised exhaust exits - introduction 20 January 2012
For 2012 the FIA has effectively banned blown diffusers by placing new restrictions on the positioning of exhaust exits. These can no longer be on the floor immediately ahead of the diffuser (red cross), but must instead be further forward and higher (black arrow). Furthermore, as seen here the final section of the exhaust pipe (one each side of the car) must be straight and completely round in section, with no internal divisions.
