The invention discloses a cabin front longitudinal beam structure. The front longitudinal beam structure comprises a front longitudinal beam middle front section and a front longitudinal beam rear section which are connected by welding, and the front longitudinal beam middle front section comprises a first area, a second area, a third area and a transition subarea connected with the first area, the second area and the third area. The front longitudinal beam rear section comprises a fourth area, a fifth area, a sixth area, a seventh area, an eighth area and the transition subarea connected withthe fourth area, the fifth area, the sixth area, the seventh area and the eighth area. A material thickness of the first area is 1.3-1.5 mm; the material thickness of the second area is 1.6 to 1.8 mm; the material thickness of the third area is 1.3-1.5 mm; the material thickness of the fourth area is 1.3-1.5 mm; the material thickness of the fifth area is 1.7-1.9 mm; the material thickness of thesixth area is 2.1 to 2.3 mm; the material thickness of the seventh area is 1.7-1.9 mm; and the material thickness of the eighth area is 1.1-1.3 mm. The invention further discloses an automobile applying the front longitudinal beam structure. The middle-front section and the rear section of the front longitudinal beam are designed in a partitioned mode, differentiated material thicknesses are designed for all the areas, and an effect that different areas have different strength is achieved.
