FIELD: transport.SUBSTANCE: proposed structure comprises extension element extending downward from front underfloor surface to redirect incident airflow that flows over said front underfloor surface. Said extending element is configured as the extending element with bent surface (31) located closer to vehicle front than front tires and at front underflow structure centre, right around vehicle central line. Extending element with bent surface (31) has the circle of extension in lengthwise direction of the vehicle which features maximum length at the vehicle central line position (CL) and the circle of extension in crosswise direction gradually decreasing with increase in distance from vehicle central line (CL) on both sides in direction of vehicle width.EFFECT: lower drag.5 cl, 14 dwg |
