An automotive step-turbine engine comprising in combination a primary power turbine assembly, one or more power boost turbine assemblies and a power output demand sensor for sequentially placing in service the one or more power boost assemblies as additional power output above that capable of being economically produced by the primary power turbine assembly is required further sequentially taking the power boost turbine assemblies out of service in reverse order when the additional power is no longer required. The primary power turbine assembly and the power boost turbine assemblies are geared together synchronously and run at the same velocity. The assemblies each have an air compressor unit geared directly to the respective assembly for pumping air into burner units, one for each of the assemblies. The power boost compressors have air intake ports having port valves therein for opening the port when each power boost turbine assembly is placed into service and closing the port when each power boost turbine assembly is taken out of service. When not in service, the power turbine assembly rotating members rotate in a near vacuum thereby substantially reducing the frictional drag on the rotating members and increasing the efficiency of the engine. Opening the air intake port valves and fuel inlet valves to permit air and fuel to flow into a burner wherein the air-fuel mixture is ignited by an electrically operated igniter places the power boost turbine assemblies in service. The rotational velocity of the turbine engine\s rotating members including each turbine wheel is maintained between lower and upper rotational velocity limits defining an economical operating range for the engine with minimal power surges occurring when each power boost assembly is placed into or taken out of service as determined by the power output demand sensor.
