Wright Electric it was developing an electric 180-seater for 2027 with Wright Electric. Wright Electric built a two-seat proof-of-concept with 272kg (600lb) of batteries, and believes that batteries can be scaled up with substantially lighter new battery chemistries: a 291 nautical mile (540km) range would suffice for 20% of Easyjet passengers. Wright Electric plans to develop a 10-seater and eventually an at least 120 passengers single-aisle, short-haul airliner and targets 50% lower noise and 10% lower costs. To evaluate electric propulsion systems, two test stands were constructed: one with two 250 kW UQM motors and two Hartzell Propellers, built with Yates Electrospace,
