Falcon 6X vs G450
The Falcon 6X leads, topping 6 of 7 compared metrics.
Cross-shopping the Dassault Aviation Falcon 6X (introduced 2023) against the Gulfstream Aerospace G450 (introduced 2005) 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 Falcon 6X has the advantage. undefined

Falcon 6X vs G450: the key differences
- The Falcon 6X delivers 26% more range (Falcon 6X: 5,500 nm; G450: 4,350 nm).
- The Falcon 6X delivers 5% more cruise speed (Falcon 6X: 480 kt; G450: 459 kt).
- The Falcon 6X and G450 are evenly matched on passenger capacity, both at 16 seats.
- The Falcon 6X is the newer design (introduced 2023 versus 2005 for the G450), a gap of 18 years that usually shows up in avionics, cabin systems and fuel burn.
- The G450 is the larger aircraft by maximum takeoff weight (74,600 lbs versus 72,000 lbs), which typically buys more cabin and payload at the cost of higher trip economics.
Which mission suits which aircraft
Both aircraft are built for long-haul and transatlantic missions, so outright range rarely separates them — the call leans on cabin (the Falcon 6X seats more), trip economics and what is actually available on the market. Match the airframe to how you fly most weeks, not to the headline range figure.
Which should you choose?
On published specifications the Falcon 6X leads on both range and cabin capacity, so it suits operators who want maximum mission flexibility from a single airframe. The G450 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.
