2012 rule changes - revised exhaust exits - side view 20 January 2012
As part of moves to outlaw blown diffusers, the FIA has imposed new restrictions on the positioning of exhaust exits for 2012. There can only be one exit on each side of the car and it must fall within the yellow dotted line shown here. In practice this is a box 700mm long (between 500mm and 1200mm from the rear axle), 350mm high (between 250mm and 600mm above the reference plane, RP) and 300mm wide (see separate article for overhead view). On top of that, the last 100mm of the pipe (red arrow) must be straight and round in section, and must be angled between 10° and 30° longitudinally.
