Falcon 6X vs G650ER
The G650ER leads, topping 3 of 7 compared metrics.
The Dassault Aviation Falcon 6X (introduced 2023) and the Gulfstream Aerospace G650ER (introduced 2014) are two aircraft buyers regularly weigh against each other. Both are business jets, which makes them natural cross-shopping rivals. The clearest separation between them is range, where the G650ER has the advantage. We line the numbers up below, then translate them into the mission each aircraft actually wins.

Falcon 6X vs G650ER: the key differences
- The G650ER delivers 36% more range (Falcon 6X: 5,500 nm; G650ER: 7,500 nm).
- The G650ER delivers 6% more cruise speed (Falcon 6X: 480 kt; G650ER: 507 kt).
- The G650ER delivers 19% more passenger capacity (Falcon 6X: 16 seats; G650ER: 19 seats).
- The Falcon 6X is the newer design (introduced 2023 versus 2014 for the G650ER), a gap of 9 years that usually shows up in avionics, cabin systems and fuel burn.
- The G650ER is the larger aircraft by maximum takeoff weight (103,600 lbs versus 72,000 lbs), which typically buys more cabin and payload at the cost of higher trip economics.
Which mission suits which aircraft
The G650ER is the stronger fit for nonstop ultra-long-haul routes — its 7,500 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 G650ER's extra capability is range you pay to carry but rarely use.
Which should you choose?
On published specifications the G650ER 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.
