Model CF6-80C2

High Reliability, Long Life, Low Fuel Burn
The CF6-80C2 is one of the most reliable commercial jet engines in the world.

Engine Overview

The CF6-80C2 high-bypass turbofan engine combines a proven core with the latest technical innovations to offer the highest reliability, longest life, and lowest fuel burn in its thrust class.

Technologies from a variety of research and development program have been incorporated in the CF6-80C2 design, such as advanced cooling techniques to improve overall efficiency, advanced clearance control, and aerodynamic modifications of blades and vanes. CF6 technology advances such as a new low emissions combustor and advanced high pressure turbine will maximize customer value well into the 21st century.

The CF6-80C2 entered revenue service in October 1985 and has consistently demonstrated the lowest specific fuel consumption of any commercial transport engine in its thrust class.

Currently certified on 11 widebody aircraft models and with 16 ratings, the CF6-80C2 has received FAA 180-minute Extended Twin-engine Operations (ETOPS) for the A300, A310, and B767 aircraft, offering route structuring flexibility and added economic benefits.
