The invention discloses a scheme for a power system of a novel pneumatic-fuel oil multistage hybrid power vehicle. The power system comprises an engine (1), an air compressor (2), a throat pipe (5), a reducing valve (6), a high pressure gas storage tank (7), a gas mixture chamber (8), a pneumatic motor (9), a differential mechanism (11) and a planetary mechanism (12). Parts of mechanical energy output by the engine (1) is used for driving the air compressor (2), compressed gas discharged from the air compressor (2) is mixed with high pressure air discharged from the high pressure gas storage tank (7), the mixed gas is subject to depressurization by the throat pipe (5) and is further mixed with tail gas discharged by the engine in the gas mixture chamber (8) to drive the pneumatic motor (9); the rest of the mechanical energy is output to the planetary mechanism (12) by a transmission to be mixed with power output by pneumatic motor (9) and then output to the differential mechanism (11) to finally drive wheels
