Renault R28 - revised sidepods

Renault R28 - revised sidepods
Most teams have stopped development work on their 2008 cars but Renault are an exception to the rule, bringing a heavily revised R28 to Fuji. The car's sidepods have been dramatically reduced in their cross section at the front, with the radiator inlets featuring a more tapered side profile (see red arrow). This change dramatically improves the aerodynamic effectiveness - and hence balance - of the car by reducing drag and improving the efficiency of the rear wing and diffuser.
