The invention relates to the technical field of automobiles, and particularly discloses a coaxial electric drive system and a vehicle. According to the coaxial electric drive system, the motor assembly, the differential mechanism and the speed reduction mechanisms are all arranged in the shell assembly, integration of the motor, the differential mechanism and the speed reduction mechanisms is achieved, the two speed reduction mechanisms on the left side and the right side are symmetrically arranged and integrated in the shell assembly, and the axial distance can be greatly shortened; the two output ends of the coaxial electric drive system are symmetrically arranged, so that the arrangement of the whole vehicle is facilitated; and the planet carrier and the shell assembly are integrally designed, so that the types and the number of parts are effectively reduced. According to the coaxial electric drive system, through the highly integrated design, the axial occupied space is shortened, the requirement for the arrangement space is small, arrangement of other components is not affected, and the coaxial electric drive system can be suitable for various vehicle types.
