CF6Engine family

GE Aerospace

Setting the standard

for widebody aircraft engines
GE Aerospace’s CF6 engine family remains the longest-running jet engine program in commercial aviation, having entered service in 1971 as GE Aerospace’s first successful power plant for the commercial widebody aircraft segment. The CF6-80C2 continues in production today.

In addition to marine and industrial applications, GE Aerospace has delivered more than 8,500 CF6 engines to power 10 unique commercial and military aircraft families with 25 variants. The most popular engine model, the CF6-80C2, boasts the largest installed base of any widebody engine in history.

    Getting better and better.
    Compared to the first CF6-6, today’s fleet is:
    • More powerful with almost 70,000 lbs. of thrust on the CF6-80E (vs. 40,000 lbs. of thrust on CF6-6)
    • Up to 15% more fuel efficient
    • Operating with 3X more flights between overhauls

    A second life with cargo
    GE Aerospace's CF6 engine family powers nearly 70 percent of the world's widebody aircraft.

    The CF6 is the leading engine of choice for new and conversion widebody freighters due to its proven durability, reliability, and performance. As older passenger aircraft are converted into freighters, the CF6 engine offers significant advantages, including the highest widebody engine departure reliability rates, fewer flight disruptions, and extensive used material availability for lower maintenance costs.
