Bombardier Challenger 650 vs Dassault Falcon 6x vs Embraer Legacy 650e vs Gulfstream G400

The Bombardier Challenger 650 and Embraer Legacy 650E sit in the large-cabin, long-range business jet category, with broadly similar missions focused on comfortable transcontinental flying rather than ultra-long-haul. In range terms, both are typically cited around the 3,900–4,000 nautical mile class, making them well suited to North America coast-to-coast or many Atlantic city pairs with favorable winds. Passenger capacity is usually configured for about 9 to 12, with maximum certified layouts higher. The Dassault Falcon 6X is a newer-generation large-cabin, long-range jet that steps up in both capability and cabin volume versus the Challenger/Legacy class. Its published range is commonly cited around 5,500 nautical miles, enabling more nonstop intercontinental routes, and it is generally configured for roughly 12 to 16 passengers. The Gulfstream G400 is positioned as a large-cabin, long-range aircraft between traditional super-midsize and flagship ultra-long-range models. Its published range is around 4,200 nautical miles, offering more reach than Challenger/Legacy while typically seating about 10 to 12 in executive layouts, with higher-density options available.
