Dassault Falcon 6x vs Dassault Falcon 7x vs Dassault Falcon 8x vs Gulfstream G650 vs Gulfstream G800

Dassault’s Falcon 6X is primarily a large-cabin, long-range business jet focused on cabin comfort and transoceanic capability, with a range of about 5,500 nautical miles and typically seating around 12–16 passengers depending on layout. The Falcon 7X is an earlier ultra-long-range trijet, generally positioned a step above the 6X in endurance, offering roughly 5,950 nautical miles of range and similar typical seating (about 12–16). The Falcon 8X is the 7X’s longer-legged evolution, still an ultra-long-range trijet but optimized for efficiency and mission flexibility, with about 6,450 nautical miles of range and a comparable cabin capacity (commonly 12–16). Gulfstream’s G800 sits in the top tier of ultra-long-range large-cabin jets, generally exceeding the Falcons on published range with about 8,000 nautical miles, and is typically configured for around 12–19 passengers. Overall, the 6X targets long-range comfort below the trijet Falcons in reach, the 7X and 8X specialize in ultra-long-range missions with the 8X leading Dassault’s range, and the G800 is aimed at the longest nonstop city pairs with higher maximum capacity potential.
