Gulfstream G400 vs Gulfstream G650er
The Gulfstream G400 and Gulfstream G650ER sit in different segments of Gulfstream’s long-range lineup. The G400 is positioned as a large-cabin, long-range business jet aimed at intercontinental missions, offering a balance of cabin space, operating economics, and transoceanic capability. The G650ER is a flagship ultra-long-range large-cabin jet designed for the longest nonstop city pairs and maximum time in the air at high cruise speeds. On range, the G650ER has a clear advantage, with a published maximum range around 7,500 nautical miles, enabling more nonstop routes and greater routing flexibility with headwinds and reserves. The G400 is also long-range but shorter-legged, published around 4,200 nautical miles, which suits many transcontinental and some transatlantic missions but not the longest intercontinental sectors. Passenger capacity differs accordingly: the G400 is typically configured for roughly 9 to 12 passengers, while the G650ER commonly seats about 14 to 19, depending on layout. Overall, the G400 targets long-range capability in a slightly smaller class, while the G650ER prioritizes maximum range and higher typical occupancy.
