Dassault Falcon 6x vs Dassault Falcon 8x vs Gulfstream G650er vs Gulfstream G700

In category, the Dassault Falcon 6X and Gulfstream G700 sit in the large-cabin, long-range class, while the Dassault Falcon 8X and Gulfstream G650ER are ultra-long-range flagships, with the G700 also often positioned as the newest ultra-long-range large-cabin entrant due to its size and performance. For range, the Falcon 6X is designed for long-range missions at about 5,500 nautical miles, the Falcon 8X extends to roughly 6,450 nautical miles, the G650ER reaches about 7,500 nautical miles, and the G700 is around 7,750 nautical miles. In passenger capacity, typical configurations for all four are commonly in the 12–16 passenger range, but maximum certified counts differ: the Falcon 6X and 8X can be configured up to about 16–19, the G650ER up to about 19, and the G700 up to about 19, with the G700 generally offering the most cabin volume and living zones, while the 8X emphasizes efficiency and short-field flexibility relative to its class.
