Gulfstream G400 vs Gulfstream G500

The Gulfstream G400 and Gulfstream G500 are both large-cabin business jets, but they sit in different parts of Gulfstream’s lineup. The G400 is positioned as a long-range large-cabin jet that bridges the gap between super-midsize offerings and Gulfstream’s higher-end large-cabin models, prioritizing efficient intercontinental capability with a slightly smaller overall footprint. The G500 is a higher-tier large-cabin jet, generally viewed as a step up in capability and cabin volume, aimed at longer nonstop missions and a more spacious premium-cabin experience. In range, the G500 typically offers greater nonstop reach than the G400, enabling more city pairs without refueling and providing more routing flexibility in adverse winds or with higher payloads. For passenger capacity, both aircraft are commonly configured for roughly a similar number of passengers in typical executive layouts, but the G500’s larger cabin and higher maximum capability can better accommodate higher-density seating or more generous zones and amenities, depending on configuration.
