Gulfstream G500 vs Gulfstream G650er

The Gulfstream G500 and Gulfstream G650ER sit in different categories within Gulfstream’s lineup. The G500 is typically considered a large-cabin business jet designed for long-range missions, balancing cabin comfort with strong performance for transcontinental and many intercontinental routes. The G650ER is an ultra-long-range flagship-class aircraft built for the longest nonstop city pairs, with higher cruise efficiency at high speeds and a larger overall mission envelope. In range, the G500 is rated for about 5,300 nautical miles, making it well suited to routes such as New York to London or Los Angeles to New York with reserves, depending on conditions. The G650ER extends that capability to roughly 7,500 nautical miles, enabling true ultra-long-haul nonstop flights such as New York to Hong Kong or Los Angeles to Sydney in favorable planning scenarios. Passenger capacity also differs. The G500 is commonly configured for around 12 to 16 passengers, while the G650ER typically seats about 14 to 19, with both models’ exact capacity and comfort depending heavily on interior layout.
