The 737 Max, the latest update on Boeing best-selling single-aisle jetliner, will have better fuel economy than the company had promised, Boeing said Tuesday.
The company said detailed engineering studies of the plane's final configuration show the plane's fuel consumption will be 14 percent better than the best present single-aisle airliner in its size range. Boeing had predicted a 13 percent increase in fuel efficiency.
The updated plane, which will enter commercial service in 2017, is equipped with new engines, aerodynamic modifications and updated cockpit that includes new maintenance monitoring equipment to allow pilots to check on issues that may develop in flight.
The planes will be built in Boeing's Renton plant.
"Throughout the design process we'll continue to look for opportunities to improve performance, schedule and cost for our customers," said Keith Leverkuhn, vice president and general manager of the 737 Max program. "We are on track for first delivery in the third quarter of 2017."
