Power system and automobile

The invention relates to the technical field of automobile power, and discloses a power system and an automobile. According to the power system, an engine is in transmission connection with one end of a variable-speed shaft through a first clutch unit. The first motor and the variable-speed shaft are arranged at intervals in the radial direction of the variable-speed shaft. The first motor is in transmission connection with the variable-speed gear set. The second motor is located on the outer side of the first clutch unit, connected with the first clutch unit and in transmission connection with the variable-speed shaft. The orthographic projection of the first motor on the projection plane at least partially coincides with the orthographic projection of the variable-speed shaft on the projection plane. And the second motor is located on the outer side of the first clutch unit and connected with the first clutch unit, so that the compactness of the power system is improved, and the size of the power system is
