Bombardier Challenger 650 vs Gulfstream G600

The Bombardier Challenger 650 and Gulfstream G600 sit in different business-jet categories: the Challenger 650 is a large-cabin jet aimed at high comfort and strong value on medium-to-long missions, while the Gulfstream G600 is an ultra-long-range, large-cabin jet positioned a tier higher in performance and intercontinental capability. In range, the Challenger 650 is typically cited around 4,000 nautical miles class (about 4,000 nm), suitable for many transcontinental and select North Atlantic routes depending on payload and winds, whereas the G600 is commonly listed around 6,600 nautical miles, enabling more nonstop intercontinental city pairs with greater margin. Passenger capacity is broadly similar in typical executive layouts, with the Challenger 650 often configured for about 9 to 12 passengers and the G600 commonly accommodating about 10 to 13, though both can be arranged differently depending on operator preferences. Overall, the G600 emphasizes longer nonstop reach and higher-end performance, while the Challenger 650 focuses on spacious cabin comfort and mission flexibility at a lower operating tier.
