Bombardier Challenger 650 vs Dassault Falcon 8x vs Dassault Falcon 900lx vs Gulfstream G650er

By category, the Bombardier Challenger 650 is typically positioned as a large-cabin business jet, while the Dassault Falcon 900LX and Falcon 8X are long-range, large-cabin/ultra-long-range business jets, and the Gulfstream G650ER is a flagship ultra-long-range, large-cabin jet. On range, the Challenger 650 is best for transcontinental missions at roughly 4,000 nautical miles, suitable for many North America and some transatlantic city pairs with favorable conditions. The Falcon 900LX extends that capability into true long-range territory at about 4,750 nm. The Falcon 8X steps up further to around 6,450 nm, enabling more nonstop intercontinental routes with added flexibility. The G650ER offers the longest reach here at roughly 7,500 nm, optimized for premier nonstop global city pairs. For passenger capacity, all can be configured variably, but typical layouts trend smaller on the Challenger 650 (often about 10–12 passengers). The Falcon 900LX commonly seats around 12–14, the Falcon 8X around 12–16, and the G650ER often around 14–16, with higher-density configurations possible across the group.
