Dassault Falcon 6x vs Dassault Falcon 7x vs Dassault Falcon 8x vs Gulfstream G650er vs Gulfstream G800

In category, Dassault’s Falcon 6X, 7X, and 8X are large-cabin, long-range business jets, while Gulfstream’s G650ER and the newer G800 sit in the ultra-long-range, flagship class with generally larger cabins and higher cruise capability. On range, the Falcon 6X is the shortest-legged of this group at roughly 5,500 nautical miles, the Falcon 7X steps up to about 5,950 nm, and the Falcon 8X extends further to around 6,450 nm. The Gulfstream G650ER typically offers about 7,500 nm, and the G800 reaches roughly 8,000 nm, making it the longest-range option here. On passenger capacity, all can be configured for typical executive layouts around 12–16 passengers, but maximum certified seating generally trends higher on the Gulfstreams: Falcon 6X is commonly up to about 16, Falcon 7X and 8X up to about 19, the G650ER up to about 19, and the G800 up to about 19 (with typical layouts still focused on comfort rather than maximum seats). Actual range and seating vary with configuration and mission profile.
