This invention relates to a hybrid gas turbine (HGT) engine powerplant having electrical output power and as a system independently or in combination with electrical energy storage means, supplies electrical power to at least one electric motor for vehicular propulsion. The HGT has a minimum of two spools at least one spool, the power spool, has integrated a compressor rotor, turbine rotor and alternator rotor; a minimum second spool for staged engine air compression has integrated a compressor and turbine rotors aero-coupled to the power spool. An electronic engine unit (EECU) supplies electrical power to the fuel control valve, has preprogrammed variable power spool speeds per output power requirements, exhaust gas turbine temperature limits for fuel economy considerations and is responsive thru vehicle throttle commands of accel, decel, constant vehicle operations, start-up, shut down, battery charger and auxiliary power applications (APU).
