Gulfstream G400 vs Gulfstream G500 vs Gulfstream G650er vs Gulfstream G800 1

In category, the Gulfstream G400 and G500 sit in the large-cabin, long-range segment, with the G400 positioned as the smaller, more range-focused step below the G500. The G650ER and G800 are ultra-long-range, flagship-class aircraft, with the G650ER representing Gulfstream’s established top-end performance and the G800 being the newer-generation successor platform. On range, the G400 is designed for transoceanic missions at about 4,200 nautical miles, while the G500 extends that capability to roughly 5,300 nautical miles. The G650ER steps up dramatically to around 7,500 nautical miles, enabling many nonstop intercontinental city pairs. The G800 leads the group, at about 8,000 nautical miles, pushing the longest nonstop missions even further. Passenger capacity is broadly similar in typical executive layouts, but scales with cabin size: the G400 and G500 commonly seat about 9 to 13 passengers, while the larger-cabin G650ER and G800 are often configured for about 12 to 16 passengers, with higher maximum-density limits available depending on certification and interior.
