A system and method for controlling a hybrid vehicle having an engine, first and second electric machines coupled to a traction battery and configured to operate primarily as a motor and a generator, respectively, and a controller in communication with the engine and the first and second electric machines include increasing target engine speed from a sea level speed to deliver a demanded engine power at altitude up to an NVH engine speed limit. The system and method may reduce the demanded engine power based on an attainable engine power associated with the NVH engine speed limit. A demanded wheel power may be reduced in response to the reduced engine power.
