Sauber C24 - chimneys 28 May 2005
A curious chimney design for the European round. Curious because the top is closed, hence they don't have the function of hot-air venting. Also curious because they are visibly curved outwards, not just inclined as on most cars. Their main function therefore looks to be diverting airflow outwards, away from the rear wheels, to reduce turbulence and refine the airflow impacting the rear wing.
