Bombardier Challenger 3500 vs Bombardier Challenger 650 vs Gulfstream G500 vs Gulfstream G650er vs Gulfstream G700 vs Gulfstream G800 1

By category, the Bombardier Challenger 3500 is a super-midsize jet, while the Challenger 650 is a large-cabin jet. Gulfstream’s G500 sits in the large-cabin, long-range class, whereas the G650ER is an ultra-long-range large-cabin flagship. The G700 and G800 are Gulfstream’s newest ultra-long-range large-cabin models, with the G700 emphasizing maximum cabin volume and the G800 emphasizing maximum range. On range, the Challenger 3500 is best for transcontinental missions (roughly mid‑3,000 nm class), and the Challenger 650 extends that into the ~4,000 nm class. The G500 typically reaches the ~5,000 nm class, enabling many North Atlantic and deep U.S. coast-to-coast missions with more margin. The G650ER is in the ~7,500 nm class, designed for true intercontinental nonstop capability. The G700 is around the mid‑7,000 nm class, while the G800 stretches furthest, roughly ~8,000 nm class. On passenger capacity, Challengers commonly seat about 8–10 in typical executive layouts, while the Gulfstreams generally accommodate about 10–16 depending on configuration, with the G700/G800 often arranged for larger groups and multiple living zones.
