Powering today's most efficient single-aisle aircraft
Airbus A320neo family
Seating 120 to 220 passengers in a typical 2-class layout, the A320neo family flies up to 4,700 nautical miles with the A321XLR. GTF engines deliver the highest fuel efficiency for the family. With the GTF Advantage engine, operators will benefit from 4-8% more takeoff thrust, enabling higher payload and longer range, unlocking new destinations for airlines.
Airbus A220
Seating 100 to 150 passengers in a typical 2-class layout, the A220 family flies up to 3,450 nautical miles. Powered exclusively by GTF engines, the aircraft reduces fuel consumption up to 25% per seat vs. prior-generation aircraft.
Embraer E-Jets E2
Seating 97 to 120 passengers in a typical 3-class layout, the E190-E2 and E195-E2 fly up to 2,850 nautical miles. Powered exclusively by GTF engines, the E-Jets E2 family reduces fuel consumption up to 25% per seat vs. prior-generation aircraft. Embraer and Pratt & Whitney have successfully tested the E195-E2 on 100% synthetic aviation fuel (SAF). Watch more.
The Best is getting even better
The GTF engine already delivers the most efficient power for Airbus A320neo family aircraft. Building upon mature dispatch reliability, the Pratt & Whitney GTF Advantage™ engine for the A320neo family makes the best even better, extending our leadership with even greater capability, efficiency and environmental benefits.
Architecture
A bigger, more efficient fan brings you a quieter engine and the highest bypass ratio in commercial aviation.
- Up to 81-inch fan diameter
- Up to 12:1 bypass ratio
A slow fan and a fast core mean peak performance with no compromises – each part runs at its optimum speed.
- 40% slower fan speed
- 2,000 airfoils eliminated
A fundamental shift in jet engines, seven moving parts unlock high performance through a proven geared architecture.
- 3:1 gear ratio
- Millions of hours of operation
Compressing air is hard work. That’s why the GTF engine shares the load effectively between its high and low pressure spools. Its integrally bladed rotors (IBRs) innovatively increase efficiency.
- 60% higher pressure ratio
- 3-stage low pressure compressor (LPC)
- 8-stage high pressure compressor (HPC)
- Up to 2 fewer stages than conventional turbofans
Lightweight and green. High-speed turbines coated with the latest in material technology can operate in extreme temperatures. Along with a simplified combustor, the result is optimum efficiency and cleaner skies.
- 2-stage high pressure turbine (HPT)
- 3-stage low pressure turbine (LPT)
- Up to 4 fewer turbine stages than conventional turbofans
Powered by an industry-leading geared architecture, the GTF is unlike any engine that’s come before it. With pioneering technology that enables further evolution and performance enhancements in the future, the GTF is truly in a league of its own.

Spotters guide
Has the GTF engine powered your flight?
We’re here to help you find out.
Engines manufactured by Pratt & Whitney have been soaring the skies for a century. With so many flying, it can be hard to tell just what engine is powering your aircraft. Our spotters’ guide provides key visual cues of how to tell if a GTF engine is powering your flight.
Fan Blades
Take a look at (or through) our fan blades
With such a large fan diameter, they can be hard to miss. Our fan blades bring you the highest bypass ratio in commercial aviation and are built from high strength aluminum alloy, some of the most durable and lightweight in operation today.
Rub Strips
Taking green to new heights
Housed inside the Collins Aerospace nacelle, our engine rub strips provide a key green color identifier while also playing an essential role in reducing friction and excess noise during flight.
Nose Cone
Front and center, helping lead the way
On all GTF engines, you'll see a distinct raindrop spinner painted on the nose cone. This symbol helps the grounds crew know when the motors are spinning and in operation.
Nacelle
The whole package, inside and out
Housed within a Collins Aerospace nacelle, the geared engine architecture delivers higher efficiency at a lower temperature. With a core-mounted accessory gearbox, the GTF engine achieves a slimmer, completely round nacelle for lighter weight, maximum efficiency, and improved airflow.
