Gulfstream G600 vs Gulfstream G650er

The Gulfstream G600 and Gulfstream G650ER sit in adjacent segments of Gulfstream’s long-range lineup, with the G600 generally positioned as a large-cabin, long-range business jet and the G650ER as a flagship ultra-long-range aircraft. In category terms, the G600 is a newer-generation large-cabin jet optimized for a blend of range, runway performance, and operating efficiency, while the G650ER is designed primarily to maximize nonstop intercontinental reach at very high cruise speeds. On range, the G650ER leads clearly, offering about 7,500 nautical miles, enabling more city pairs nonstop. The G600 is still firmly long-range, typically around 6,600 nautical miles, covering most transoceanic missions but with less margin on the longest routes. For passenger capacity, both are commonly configured for roughly 14 to 19 passengers in typical executive layouts, but the G650ER’s larger cabin can be arranged to accommodate more in higher-density configurations, while the G600 is usually aimed at slightly fewer passengers with more space per traveler.
