The GEnx is the fastest-selling engine in GE Aviation history with more than 1,300 engines on order. Compared to GE's CF6 engine, the GEnx engine offers up to 15 percent better fuel consumption, which translates to 15 percent less CO2. The engine is a giant leap forward in propulsion technology, using the latest generation materials and design processes to reduce weight, improve performance and lower maintenance.
Key to this outstanding performance are technologies such as the high pressure compressor, the twin-annular pre-swirl (TAPS) combustor, and lightweight, durable composite materials and specialized coatings. It is the world's first commercial jet engine with both a front fan case and fan blades made of carbon fiber composite material. It is the quietest, most passenger-friendly commercial engine GE has ever produced.
