At the Paris Air Show, Airbus demonstrated a modified A320 fitted with its electric green taxiing system (EGTS), which was developed by EGTS International—a joint venture of Safran and Honeywell.

One wheel on each main gear is equipped with an electric motor, reduction gearbox and clutch assembly to drive the aircraft during taxi operations, with power electronics and system controllers allowing pilots to control its speed and direction.
The EGTS is powered by the aircraft’s auxiliary power unit (APU) generator, allowing the aircraft to move around the tarmac without using its main engines.
