The LEAP-1B® has been selected by Boeing as the exclusive powerplant for the new 737 MAX single-aisle jetliner. It offers 737 MAX operators exceptional technical, economic and environmental performance, with a 15% reduction in fuel consumption and CO2 emissions versus current engines, a 50% cut in NOx emissions, and compliance with the most stringent noise standards (the ICAO's Chapter 14 regulations).
The selection of the LEAP-1B by Boeing in 2011 continues a long-established partnership between CFM and the aircraft manufacturer. This trust was shown to be well-founded in June 2014, when ground testing of the LEAP-1B started, three days ahead of the original schedule, at Snecma's Villaroche facility.
