When compared with last year's car, the R28's new sidepods have been transformed. The vertical fins (larger red arrow) no longer support the rear-view mirrors, making for a cleaner design and better airflow management towards the rear of the car. In addition the bottom edge of the sidepod's air inlets are much higher than before (smaller red arrow) to provide the radiators with cleaner airflow and reduce the effect of turbulence generated by the front axle and suspension.Renault R28 - front bridge wing
In comparison to its predecessor, the new Renault's nosecone has been dramatically lowered and now features an additional bridge profile (top arrow). While the front of the chassis has been minimised, the surface area of the wing's main profile has been increased. In addition the pillars (bottom arrow), which connect the nose to this profile, have been dramatically inclined to an almost horizontal position to reduce drag and improve the quality of airflow passing over and underneath the front of the car.
