The foundation of the LEAP engine is heavily rooted in advanced aerodynamics, environmental (noise and emissions), and materials technologies.
These technologies enable higher propulsive and thermal efficiency, resulting in better fuel efficiency. All this technology comes with CFM’s legendary reliability and low lifecycle maintenance costs.

CFM is supporting industry initiatives to approve and adopt 100% Sustainable Aviation Fuel (SAF).
LEAP engines are compatible with currently approved 50% SAF blends and have successfully flown multiple demonstration flights with 100% SAF, including an Airbus A321neo flight in which both engines were operating on 100% SAF.
