Bombardier Global 5500 vs Bombardier Global 6500 vs Dassault Falcon 6x vs Dassault Falcon 8x vs Gulfstream G500 vs Gulfstream G600

All six are long-range, large-cabin business jets, but they split into two broad tiers. The Bombardier Global 5500 and Gulfstream G500 sit in the “large-cabin, long-range” category: each typically carries about 8–19 passengers depending on layout, with ranges roughly in the 5,000–6,000 nautical mile class (about 5,900 nm for Global 5500 and about 5,300 nm for G500). Stepping up, the Bombardier Global 6500, Dassault Falcon 8X, and Gulfstream G600 are “ultra-long-range” large-cabin jets, generally accommodating about 8–19 passengers, and reaching around the mid‑6,000 nm class (about 6,600 nm for Global 6500, about 6,450 nm for Falcon 8X, and about 6,600 nm for G600). The Dassault Falcon 6X is best viewed as a new-generation large-cabin, long-range jet bridging the gap: it typically seats about 8–16 (up to around 19) with range around 5,500 nm. In short, for maximum reach, Global 6500/G600/Falcon 8X lead, while Global 5500/G500 emphasize slightly shorter missions.
