BMW Sauber F1.08 - barge board development
This solution (circled) was the first aero development the team applied to the car, even before the 'delta winglets' were added on the nose, and remains an important part of the car's basic aero package, after both wind tunnel results and CFD calculations confirmed its importance in increasing the efficiency and stability of the F1.08. The barge board development manages the airflow in the troublesome area in front of the sidepods. As well as providing the correct cooling, the solution directs the flow of air to the rear end of the car, in particular towards the main profile of the rear wing.
BMW Sauber F1.08 - nose winglets
This is, without doubt, one of the most radical solutions seen so far in 2008 and was introduced by BMW Sauber to try to optimise the F1.08's balance. The solution provides a better quality of airflow to the car's sidepod inlets and rear end, without generating a noticeable amount of downforce. The on-board camera housings (1) have been placed at a level where they redirect air towards the 'delta winglets' (2), thus improving the flow of air to the car's sidepods. This is especially important, as BMW Sauber have followed the trend to taper the car's sidepods at the bottom, with smaller inlets and radiators of a smaller cross-sectional area.
