Ferrari F2005 - side detail 25 February 2005
Two big fins (1) curve outwards, working almost as barge boards, splitting the airflow in two, with the central portion directed to the rear wing. Fins could be substituted with chimneys at hotter races. Exhaust exits (2) are chimney-less and further forward and more central than on 2004 car so as not to disrupt airflow to the rear wing (also further forward under 2005 regulations). Stepped bottom features small diffuser-like shape in front of rear wheels (3) to release air under the car efficiently and with minimal turbulence.
