Bombardier Challenger 650 vs Embraer Praetor 500 vs Embraer Praetor 600 vs Gulfstream G600

The Bombardier Challenger 650 and Embraer Praetor 600 sit in the large-cabin “super-midsize/large-cabin light” overlap, while the Embraer Praetor 500 is a super-midsize jet and the Gulfstream G600 is a true long-range large-cabin jet. In range terms, the Praetor 500 is typically around 3,300–3,400 nm class, the Challenger 650 about 4,000 nm, the Praetor 600 about 4,000+ nm (roughly 4,000–4,100 nm class), and the G600 substantially farther at roughly 6,000+ nm (about 6,500 nm class), enabling many more nonstop intercontinental city pairs. Passenger capacity also scales with cabin class: the Praetor 500 commonly seats about 8–9 passengers, the Challenger 650 and Praetor 600 are typically configured around 9–12 passengers, and the G600 is often arranged for about 10–14 passengers, with more space and amenities for longer missions. Overall, the Praetor 500 targets efficient transcontinental missions, the Challenger 650 and Praetor 600 compete for longer North Atlantic-capable profiles, and the G600 is aimed at high-end long-range global travel.
