Bombardier Challenger 650 vs Bombardier Global 6500 vs Gulfstream G400

The Bombardier Challenger 650 is a large-cabin business jet typically positioned for shorter long-range missions, offering about 4,000 nautical miles of range and usually seating around 8–12 passengers, with a practical emphasis on comfortable transcontinental flying and strong airport versatility. The Bombardier Global 6500 steps into the ultra-long-range category, stretching capability to roughly 6,600 nautical miles and commonly accommodating about 10–16 passengers, making it better suited to frequent intercontinental missions with more cabin volume and higher-end amenities. The Gulfstream G400 sits in the large-cabin, long-range class between these two: it’s designed for roughly 4,200 nautical miles of range and typically seats around 8–12 passengers, targeting transoceanic-capable missions on many city pairs while keeping operating economics and cabin size closer to the large-cabin segment than true ultra-long-range aircraft. Overall, the Challenger 650 prioritizes proven large-cabin comfort on shorter long-range routes, the Global 6500 maximizes intercontinental reach and space, and the G400 aims to split the difference with modern Gulfstream design and mid-to-upper long-range performance.
