McLaren MP4-23 - reduced radiator inlets 07 September 2008
The low ambient temperatures at Spa allow the teams to reduce the venting required for cooling, hence improving the aero efficiency of the cars. McLaren have been able to dramatically reduce their radiator inlets by applying a specially profiled bodywork addition in the lower section of the inlet. The reduction in the size of the openings helps reduce drag and turbulence immediately in front of the sidepods, aiding top-end performance on the Belgian circuit's long straights. Adequate airflow management ensures cooling efficiency is still maintained, hence avoiding any potential reliability problems.
