Dassault Falcon 8x vs Gulfstream G400 vs Gulfstream G600
The Dassault Falcon 8X, Gulfstream G400, and Gulfstream G600 all sit in the long-range business jet market, but they span different tiers. The Falcon 8X is typically considered an ultra-long-range, large-cabin trijet, optimized for very long nonstop missions and operational flexibility; it is commonly configured for roughly 12–16 passengers (with maximum layouts higher). The Gulfstream G400 is positioned as a large-cabin, long-range jet below the G500/G600 class, aimed at transcontinental-plus missions; typical seating is also around 12–16 passengers, depending on cabin layout. The Gulfstream G600 steps up as an ultra-long-range, large-cabin aircraft with greater intercontinental reach than the G400; it is commonly configured for about 13–17 passengers (again with higher maximums possible). In range terms, the Falcon 8X and G600 are closer peers, each offering true intercontinental capability, while the G400 generally delivers somewhat shorter—but still long-range—nonstop performance within a large-cabin footprint.
