The Shared Powerplant: Unpacking the Engine Link Between Boeing s 737 MAX and the Airbus A320neo

While both the Boeing 737 MAX and the Airbus A320neo offer the CFM International LEAP engine, they do not use the exact same model. The 737 MAX is exclusively powered by the LEAP-1B variant, which is specifically designed for the aircraft. In contrast, the A320neo family uses the LEAP-1A model, which features a larger fan. This design difference is primarily due to the 737's lower ground clearance, requiring a smaller engine nacelle. Furthermore, Airbus A320neo customers have an alternative engine choice with the Pratt & Whitney PW1000G, an option not available for the 737 MAX.
