Boeing 737 MAX - is the designation of a new generation of medium-range airliners in the Boeing 737 family, currently in development by the Boeing Corporation. This new generation is meant to replace the Boeing 737NG (Next Generation) series, which includes the models 737-600, -700, -800 and -900.
The latest upgrade of the Boeing-737 series includes new, more efficient LEAP-1B engines from CFM International and several modifications to the fuselage and wings. The planes will be outfitted with Boeing’s latest Sky Interior cabin design, which became an option on Boeing 737s in 2011.
The Boeing 737 MAX series will include three base models: 737 MAX 7 (meant to replace the Boeing 737-700), 737 MAX 8 (to replace the Boeing 737-800) and 737 MAX 9 (to replace the Boeing 737-900). The first of these airliners is expected to enter service in 2017.
