Bombardier Challenger 650 vs Bombardier Global 5500 vs Dassault Falcon 6x vs Dassault Falcon 900lx vs Gulfstream G400

By category, the Bombardier Challenger 650 is a large-cabin business jet (often positioned as “super-midsize/large-cabin”), while the Bombardier Global 5500, Dassault Falcon 6X, Dassault Falcon 900LX, and Gulfstream G400 compete in the long-range, large-cabin segment (with the Global 5500 and 6X generally regarded as “ultra-long-range” class entrants, and the 900LX and G400 as long-range large-cabin). On range, the Challenger 650 is the shortest-legged of the group at roughly 4,000 nautical miles. The Falcon 900LX and Gulfstream G400 sit in the next band, typically around the mid‑4,000s to high‑4,000s nautical miles. The Global 5500 and Falcon 6X lead this comparison, each around the 5,500–5,700 nautical mile class depending on configuration and conditions. On passenger capacity, typical executive layouts cluster around 8–14 passengers across all five, but maximum certified capacity tends to be lower on the Challenger 650 (commonly up to about 12–16) and higher on the larger long-range jets (often up to about 16–19, depending on model and interior).
