... line, almost without discontinuities. Windshield rake and marked lateral curvature are fundamental for a correct blending of the greenhouse into the body within the boundarylimit of overall surface, in order not to promote any turbulences at the increasingly wider crosssections. Also the reduction of the decreasing crosssections is suitably gradual and the tail is truncated at the minimum breakaway section compatible with the rear overhang chosen, the pressure center position and the rear end visibility requirements. The main crosssection (S) — the second factor affecting drag — was reduced by slenderizing the sides flush with the wheels, tapering the greenhouse vertically to a high degree but, especially, lowering the roof height as a consequence of the more stretched driving posture. 2. Size: one of the main aims of the design was to keep front and rear overhangs as short as possible. Front overhang length was not only dependent upon the aerodynamic requirements mentioned earlier, but also upon structural requirements which imposed the need for an additional controlledcrush section in front of the radiator, as an increased passive safety feature in case of headon collisions. Rear overhang length was reduced to the limit of the spare wheel well which was moved forward as far as possible, into contact with the rear axle crossmember; ...
