An aerodynamic vehicle has a box-like body (12) and the upper surface (13) of the body is profiled to improve the aerodynamic properties. In particular the upper surface is downwardly rearwardly inclined at the rear end (22) of said surface. To the sides of the inclined surface is formed upstanding ridges (22). When the vehicle is used with a trailer (16) with a box-like body (17) the upper surface (18) of the body is also profiled to provide inclined surfaces. At the leading end the upper surface (31) is upwardly inclined and at the rear end the surface (32) is downwardly inclined. |
