The invention relates to the technical field of automotive upholstery, and particularly discloses a lightweight automotive carpet and a preparation method thereof. A light-weight automobile carpet comprises a surface layer, a supporting layer and a sound insulation layer from top to bottom. The supporting layer comprises a first polyethylene film layer, a polyethylene foaming material layer and a second polyethylene film layer from top to bottom; the preparation method comprises the following steps: heating the surface layer, the first polyethylene film layer, the polyethylene foam material layer, the second polyethylene film layer and the polyethylene glycol terephthalate non-woven fabric layer, and carrying out compression molding to obtain a composite layer; the composite layer and the sound insulation layer are compounded and then cut, and the light-weight automobile carpet is obtained. Due to the fact that the density of the polyethylene foaming material is low, the polyethylene foaming material, the first polyethylene film layer and the second polyethylene film layer form the supporting layer of the sandwich structure, the structure is stable, the supporting performance is high, and the light-weight automobile carpet has the advantages of being light in weight and stable in structure.
