Abstract

A fastback for a passenger car is provided with a roof profile and a floor profile in the tail region. The roof profile initially descends from a highest profile point and the floor profile initially ascends from a lowest profile point in a rear axle region. The tail region forms an aerodynamic diffusor having a floor diffusor and roof diffusor. For this purpose, the roof profile features an S-shaped upward curvature toward an upper tail break-away edge and the floor profile features an S-shaped downward curvature toward a lower tail break-away edge. Due to the roof profile and the floor profile, the tail region of the passenger car has a shape with a fish-like profile.
