Manufacturing a hot-formed and press-hardened metal part for a motor vehicle, producing at least two regions of different hardness, comprises providing a curable sheet metal plate, heating to at least austenitizing temperature; intermediate cooling of the first region of the sheet metal plate; and thermoforming and press hardening the sheet metal plate to the metal component in a press hardening tool, where the first area in the press hardening tool is deterred from the bainitic phase transformation stage so that in the first area, a mixed structure of martensite and bainite is adjusted. Manufacturing a hot-formed and press-hardened metal part for a motor vehicle, producing at least two regions of different hardness, comprises providing a curable sheet metal plate, heating to at least austenitizing temperature; intermediate cooling of the first region of the sheet metal plate, where the cooling rate is chosen in such a manner that is higher than the lower critical cooling rate of the material of the sheet metal plate; and thermoforming and press-hardening the sheet metal plate to the metal component in a press hardening tool, where the first area in the press hardening tool is deterred from the bainitic phase transformation stage, so that in the first area, a mixed structure of martensite and bainite is adjusted.
