Due mostly to the new engines, I presume?
- bobthepanda 6y agoFrom the Wikipedia: > In mid-2011, one design objective was matching fuel burn of the 737 MAX to that of the Airbus A320neo's 15% fuel-burn advantage. The initial 737 Max reduction was 10–12%; it was later enhanced to 14.5%. The fan was widened from 61 in (150 cm) to 69.4 in (176 cm) by raising the nose gear and placing the engine higher and forward. The split winglet added 1–1.5% fuel burn reduction, a re-lofted tail cone added an additional 1% reduction. Electronically controlling the bleed air system improved efficiency. The new engine casings included chevrons, similar to those of the Boeing 787, which also helped to reduce engine noise.[100] But yes, mostly the engines.
