Dassault Falcon 7x vs Dassault Falcon 8x vs Gulfstream G500 vs Gulfstream G600

The Dassault Falcon 7X and 8X are large-cabin, ultra-long-range business jets, with the 8X positioned as the longer-range, slightly higher-capability evolution of the 7X. In typical operation, the 7X offers about 5,950 nm of range, while the 8X extends that to about 6,450 nm, making it better suited to longer nonstop city pairs. Both are commonly configured for roughly 12–16 passengers (with maximum layouts higher), emphasizing comfort over high-density seating. The Gulfstream G500 and G600 are also large-cabin, long-range business jets, with the G600 being the higher-performance, longer-range sibling. The G500 is typically around 5,300 nm, while the G600 is about 6,600 nm, giving it the longest range of the four. Passenger capacity is broadly similar across the Gulfstreams as well, commonly around 12–16 passengers depending on cabin layout, with maximum certified capacities higher. Overall, the “range ranking” is generally G600 and Falcon 8X at the top, followed by Falcon 7X, then G500.
