Bombardier Challenger 650 vs Bombardier Global 5500 vs Dassault Falcon 2000s vs Dassault Falcon 900lx vs Gulfstream G400

By category, the Bombardier Challenger 650 and Dassault Falcon 2000S are typically considered large-cabin business jets, while the Bombardier Global 5500, Dassault Falcon 900LX, and Gulfstream G400 sit in the long-range/ultra-long-range class (with the G400 often positioned as a new long-range large-cabin entrant). On range, the Challenger 650 and Falcon 2000S are transcontinental-capable but shorter-legged than the others, generally suited to routes on the order of roughly 3,000–4,000 nautical miles depending on payload and conditions. The Global 5500 and Falcon 900LX step up to true long-range missions, commonly quoted around the 5,000–6,000+ nautical mile class. The Gulfstream G400 is also in this long-range bracket, typically cited in the mid‑4,000 to ~5,000+ nautical mile range depending on configuration and assumptions. On passenger capacity, all can be configured for high-density seating, but typical executive layouts differ: Challenger 650 and Falcon 2000S commonly seat about 8–10; Global 5500, Falcon 900LX, and G400 more often accommodate about 10–14 with greater cabin volume and amenities.
