2012 rule changes - revised exhaust exits - overhead 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 from an overhead perspective it must fall within the yellow dotted line shown here. In practice this is a box 700mm long, 350mm high (see separate article for side view) and 300mm wide (between 200mm and 500mm from the car's centre line). On top of that, the last 100mm of the pipe (red arrow) must be completely straight and round in section, and must be angled by no more than 10° transversely, relative to the centre line.
