Bombardier Challenger 650 vs Dassault Falcon 6x vs Embraer Praetor 600 vs Gulfstream G400 vs Gulfstream G500 vs Gulfstream G600

All six are large-cabin business jets, but they span “super‑midsize” to “ultra‑long‑range.” The Bombardier Challenger 650 is a large-cabin jet optimized for comfort and reliability on transcontinental missions, typically carrying about 8–12 passengers with a range around 4,000 nm. The Embraer Praetor 600 sits at the top of the super‑midsize class, usually 7–12 passengers, with roughly 4,000+ nm range, often comparable to or slightly better than the Challenger on paper but in a somewhat smaller cabin. Dassault’s Falcon 6X is a long‑range large‑cabin jet aimed at intercontinental flying, commonly 10–16 passengers, with about 5,500 nm range. Gulfstream’s G400 is a long‑range large‑cabin model positioned below the G500/G600, typically around 10–14 passengers with roughly 4,000+ nm range. The Gulfstream G500 is a long‑range large‑cabin aircraft for true intercontinental routes, often 10–15 passengers and about 5,300 nm range. The Gulfstream G600 is the longer‑legged step up, typically 10–16 passengers with about 6,600 nm range, suited to the longest nonstop city pairs in this group.
