Gulfstream G400 vs Gulfstream G500 vs Gulfstream G600 vs Gulfstream G700

All four are large-cabin Gulfstreams, but they step up in size, range, and typical seating from the G400 through the G700. The Gulfstream G400 is positioned as the entry point of this group, a long-range large-cabin jet aimed at transcontinental and many transoceanic missions, typically accommodating about 8–12 passengers with a range in the roughly 4,000+ nautical mile class (about 4,200 nm). The Gulfstream G500 moves into the ultra-long-range large-cabin category, commonly configured for around 10–15 passengers, and is designed for longer intercontinental legs at about 5,300 nm. The Gulfstream G600 sits above the G500 as a larger ultra-long-range large-cabin aircraft, generally seating around 12–17 passengers, with range increasing to about 6,600 nm. The Gulfstream G700 is the flagship in this set, a very large-cabin ultra-long-range jet with the highest typical capacity, often about 13–19 passengers, and the longest reach at roughly 7,500 nm, optimized for the longest nonstop city pairs and the most spacious multi-zone cabin layouts.
