The ATR EVO targets a 2035 entry into service

ATR

aims to innovate and enhance sustainability with its next-generation aircraft, the ATR EVO.  The aircraft, initially planned for 2030 but now delayed until 2035, will utilize a mild hybrid propulsion system that incorporates electric motors connected to the reduction gearbox, in addition to the traditional turboprop engine.  

A Sustainability Focus

EVO will improve the sustainability of the ATR commercial turboprop product line. A key goal of the EVO propulsion system is to combine an ultra-efficient thermal engine with a battery-powered electric motor to optimize the efficiency of the propulsion system.  By utilizing electric assist for takeoff and top of climb, where more power is required, a smaller turboprop engine can be employed, thereby improving overall efficiency during other phases of flight with lower thrust requirements.
