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

In category terms, Dassault’s Falcon 6X is a large-cabin, long-range business jet positioned below the ultra-long-range tier, while the Falcon 7X and Falcon 8X are flagship tri-jets in the ultra-long-range segment. Gulfstream’s G650ER is also an ultra-long-range large-cabin jet and is generally regarded as the performance benchmark in this class. On range, the Falcon 6X is designed for long intercontinental missions at roughly 5,500–5,700 nautical miles depending on conditions and configuration. The Falcon 7X typically sits around the 5,900–6,000 nautical mile class, while the Falcon 8X extends that to about 6,450 nautical miles. The G650ER leads this comparison with an advertised range around 7,500 nautical miles, enabling more nonstop city pairs at higher payloads. For passenger capacity, all can be configured for high-density seating, but typical executive layouts differ: the Falcon 6X commonly seats about 12–16, the Falcon 7X about 10–14, the Falcon 8X about 12–16, and the G650ER often about 14–18, depending on interior choices.
