An exhaust gas drive system for engine accessories includes a turbine positioned in the exhaust system of the engine of a vehicle for rotation of the turbine by the pressure of the exhaust gas. The turbine is connected through a reduction transmission to a hydraulic pump which is fluidically connected to respective hydraulic motors which drive the accessories. Communication of exhaust gas to the turbine is controlled by a waste gate. The flow of hydraulic fluid to the hydraulic motors is controlled by actuator valves which operate in an on/off manner or are adjustable for variable control of the accessories. A computer monitors engine speed and controls the position of the waste gate to thereby maintain a substantially constant speed of the turbine. Alternatively, a secondary output shaft of the reduction transmission has a drive pulley thereon for belt driving an accessory having a driven pulley on an input shaft thereof.
