Gulfstream G400 vs Gulfstream G600
The Gulfstream G400 and Gulfstream G600 sit in different segments of Gulfstream’s large-cabin lineup. The G400 is positioned as a long-range large-cabin business jet aimed at efficient intercontinental missions, while the G600 is a larger, higher-end long-range large-cabin jet with more capability and cabin volume. In range, the G600 offers the longer reach, capable of about 6,600 nautical miles, whereas the G400 is designed for roughly 4,200 nautical miles, making the G600 better suited to longer nonstop city pairs. Passenger capacity overlaps but trends higher on the G600: both are typically configured for around 12 to 16 passengers in executive layouts, but the G600 more comfortably supports higher-end, more spacious multi-zone arrangements and can accommodate more people depending on configuration. Overall, the G400 emphasizes a slightly smaller, more cost- and mission-efficient footprint, while the G600 prioritizes maximum range, cabin space, and premium long-haul capability.
