FIELD: transportation.
SUBSTANCE: group of inventions relates to embodiments of vehicle outer panel. Vehicle outer panel comprises outer material 110 and reinforcing element 120, which is in contact along inner surface of outer material 110 of vehicle and second surface area of which in direction perpendicular to outer material, smaller than or equal to 15,000 mm4 in cross section perpendicular to longitudinal direction of reinforcing element. With such configuration, the second moment of the area in the direction perpendicular to the longitudinal direction of reinforcing element 120 is less than or equal to 15,000 mm4, and at the same time the lack of rigidity in tension can be compensated.
EFFECT: providing a configuration which compensates for lack of rigidity in tension and at the same time compensates for lack of impact properties.
