Gulfstream G500 vs Gulfstream G600

The Gulfstream G500 and G600 sit in the same family of long-range, large-cabin business jets, with the G500 generally positioned as the slightly smaller, lower-range sibling and the G600 as the higher-capability step up. In category terms, both are large-cabin, long-range jets, but the G600 is typically regarded as the “ultra-long-range” option within the pair due to its added performance margin. On range, the G600 offers a longer maximum range than the G500, making it better suited to more city-pair missions with fewer fuel stops and more flexibility in routing. The G500 still provides true long-range capability, but it is optimized for slightly shorter missions compared with the G600. For passenger capacity, both can be configured for similar headcounts depending on layout, but the G600 commonly supports higher-density configurations a bit more comfortably thanks to its larger overall capability, while typical executive layouts for both emphasize spacious seating and multiple living zones rather than maximum seats.
