Dassault Falcon 8x vs Gulfstream G650er vs Dassault Falcon 6x

In category terms, the Gulfstream G650ER sits at the top as an ultra-long-range, large-cabin business jet. The Dassault Falcon 8X is also an ultra-long-range jet but with a slightly smaller, tri-jet cabin footprint and an emphasis on operational flexibility. The Dassault Falcon 6X is a newer large-cabin jet positioned a step below true ultra-long-range models, focusing on cabin volume and comfort rather than maximum distance. For range, the G650ER typically leads at about 7,500 nautical miles, enabling some of the longest nonstop city pairs in business aviation. The Falcon 8X follows closely at roughly 6,450 nautical miles, still firmly in ultra-long-range territory. The Falcon 6X is shorter-legged at about 5,500 nautical miles, suitable for most intercontinental missions but not as many “anywhere-to-anywhere” routes. Passenger capacity is broadly similar in practice: all are commonly configured for around 12–16 passengers. The G650ER can be arranged up to about 19, while the Falcon 8X and 6X are often quoted up to about 16–18 depending on layout.
