Which engine is used on the Boeing 737-800 series?

• A. CFM 56-3 high-ratio bypass turbofan engine
• B. GE90 turbofan engine
• C. Rolls-Royce Trent 700
• D. Pratt & Whitney PW4000

Answer: (A)

For the Boeing 737-800, the engine choice is the CFM56 family, specifically the CFM56-7B. This is a high-bypass turbofan designed for the 737 Next Generation aircraft and tuned to deliver the right balance of thrust, fuel efficiency, and nacelle compatibility for the -800 series. The CFM56-3 is an older variant used on the earlier 737 Classic models (300/400/500) and doesn’t match the 737-800’s design and performance requirements. The other engines listed are tied to different airplanes: GE90 powers the 777, Trent 700 powers the A330, and PW4000 is used on various other platforms, not the 737-800. So the engine that truly powers the 737-800 is the CFM56-7B.
