Gulfstream G400 vs Gulfstream G500 vs Gulfstream G600
The Gulfstream G400, G500, and G600 are all large-cabin business jets, but they step up in size and capability as you move through the lineup. The G400 is positioned as the more compact large-cabin option, aimed at long-range missions with a slightly smaller cabin footprint and typically a lower overall passenger load. The G500 sits in the middle as a long-range large-cabin jet that balances cabin space, payload flexibility, and intercontinental reach, commonly configured for roughly 12 to 16 passengers. The G600 is the larger, higher-capability aircraft in this trio, offering the most spacious cabin and generally the greatest range, making it the best fit for longer nonstop city pairs and larger executive layouts, often around 13 to 17 passengers depending on configuration. In practical terms, choose the G400 for long-range travel with a smaller large-cabin airframe, the G500 for a versatile long-range sweet spot, and the G600 when maximum cabin room and the longest nonstop capability are the priority.
