Dassault Falcon 8x vs Gulfstream G400 vs Gulfstream G600 vs Gulfstream G800 1

In category, the Dassault Falcon 8X is a long-range large-cabin business jet, while the Gulfstream G400 is positioned as a large-cabin, long-range jet but smaller and less capable than Gulfstream’s flagship-class offerings. The Gulfstream G600 sits in the large-cabin, ultra-long-range bracket, bridging high speed and intercontinental capability, and the Gulfstream G800 is Gulfstream’s flagship ultra-long-range large-cabin model, aimed at the longest nonstop missions. For range, the G400 is the shortest-legged of the four at roughly 4,200 nautical miles. The Falcon 8X reaches about 6,450 nautical miles, enabling many transoceanic city pairs. The G600 extends further to around 6,600 nautical miles, offering slightly more reach than the 8X. The G800 leads with about 8,000 nautical miles, targeting near-global nonstop coverage. Passenger capacity is broadly similar in typical executive layouts, but scales with cabin size: the G400 generally carries about 10–12 passengers, the Falcon 8X about 12–16, the G600 about 13–17, and the G800 about 14–19, depending on configuration.
