The invention relates to a composite passenger car floor and a manufacturing method thereof. The composite passenger car floor comprises a base plate and reinforcing layers, the base plate is a rectangular plastic plate with a plurality of small through holes, the reinforcing layers are thermoplastic prepregs, and the reinforcing layers are tightly attached to the upper surface and the lower surface of the base plate, wherein the raw materials of the base plate comprise a high-density additive with the weight ratio of 20-30% and the density of 2.0-5.0 g/cm < 3 >, and the base plate is manufactured by adopting an extrusion process; the reinforcing layer is manufactured by adopting a thermoplastic prepreg manufacturing process; the fiber direction of the reinforcing layer comprises 1-3 kindsof angles of 0 degree, +/-45 degrees and 90 degrees, wherein the base plate and the reinforcing layers are compounded together through a hot pressing process to form a complete cuboid. When the baseplate and the reinforcing layers are compounded through hot pressing equipment, supports for preventing the small holes from collapsing are arranged in the small holes.
