Static wind tunnel experiments with a 1:4 scale realistic passenger car model called DrivAer were carried out under variation of yaw angle β between 0° and ± 10°. The investigation considered fastback and notchback geometries. The flow field behaviour was examined through force measurements, time resolved surface pressure measurements, and surface flow visualizations. At zero yaw angle the fastback's drag coefficient is CD=0.254 and for the notchback CD=0.258. The notchback exhibits a large and asymmetrical separated flow field whereas the fastback shows a symmetrical flow field. The separated regions shift leeward for increasing yaw angles. In general, higher pressure fluctuations are observed at the lower windward and the upper leeward base for yawed conditions.
