Falcon 6X vs G550
The G550 leads, topping 3 of 7 compared metrics.
Cross-shopping the Dassault Aviation Falcon 6X (introduced 2023) against the Gulfstream Aerospace G550 (introduced 2003) is a common decision, and the two sit closer on paper than the badges suggest. Both are business jets, which makes them natural cross-shopping rivals. The clearest separation between them is range, where the G550 has the advantage. undefined

Falcon 6X vs G550: the key differences
- The G550 delivers 23% more range (Falcon 6X: 5,500 nm; G550: 6,750 nm).
- The G550 delivers 2% more cruise speed (Falcon 6X: 480 kt; G550: 488 kt).
- The G550 delivers 19% more passenger capacity (Falcon 6X: 16 seats; G550: 19 seats).
- The Falcon 6X is the newer design (introduced 2023 versus 2003 for the G550), a gap of 20 years that usually shows up in avionics, cabin systems and fuel burn.
- The G550 is the larger aircraft by maximum takeoff weight (91,000 lbs versus 72,000 lbs), which typically buys more cabin and payload at the cost of higher trip economics.
Which mission suits which aircraft
The G550 is the stronger fit for nonstop ultra-long-haul routes — its 6,750 nm of range removes fuel stops on those legs. The Falcon 6X, at 5,500 nm, is better matched to long-haul and transatlantic missions, where lower trip cost counts for more than outright reach. If most of your flying sits inside the Falcon 6X's range, the G550's extra capability is range you pay to carry but rarely use.
Which should you choose?
On published specifications the G550 leads on both range and cabin capacity, so it suits operators who want maximum mission flexibility from a single airframe. The Falcon 6X can still be the smarter buy on acquisition cost, operating economics, runway performance, or current availability — the factors that rarely show up in a spec sheet. Our acquisition advisory team can model both against your actual mission profile before you commit.
