Airbus, Rolls-Royce and Siemens have teamed up to develop a passenger plane powered by a hybrid-electric motor.

The aim of the project — dubbed the E-Fan X — is to replace one of four gas turbine engines on a short-haul airliner with the motor for a test flight by 2020. If successful, a second gas turbine motor would then be swapped out.

"We see hybrid-electric propulsion as a compelling technology for the future of aviation," said Paul Eremenko, Airbus' chief technology officer, in a press release Tuesday.

The next big step is for German manufacturer Siemens to develop a two-megawatt motor to take power from a new Rolls-Royce generator. The wattage is comparable to about seven times the peak output from a Tesla Model S.

Airbus has previously estimated that a regional short-haul plane able to carry around 100 people would need a combined power output of about 20 megawatts.

The European aircraft manufacturer said it is building on its small two-seater hybrid-electric plane, the E-Fan Plus, which debuted in summer 2016 at the EAA AirVenture Oshkosh air show in Wisconsin.

Plans to develop that jet for commercial use have been shelved as the ambition for electric flight has now been upped to include short-haul passenger aircraft.
