The 737 MAX will deliver the significant savings in fuel that airlines require for the future. The 737 MAX improves fuel efficiency and CO2 emissions by an additional 14 percent over today’s most fuel-efficient Next-Generation 737s and 20 percent more fuel efficient than the first Next-Generation 737s to enter service. Design updates, including Boeing’s Advanced Technology winglet, also will further optimize the 737 MAX performance, especially on longer-range missions.
