Gulfstream G500 vs Gulfstream G600 vs Gulfstream G650er

The Gulfstream G500 and G600 are both in Gulfstream’s newer long-range large-cabin family, while the G650ER is a flagship ultra-long-range large-cabin jet. In category terms, the G500 is typically positioned as a long-range large-cabin aircraft, the G600 as a larger, longer-legged large-cabin step-up, and the G650ER as an ultra-long-range heavy business jet with the biggest global reach of the three. For range, the G500 is rated around 5,300 nautical miles, the G600 around 6,600 nautical miles, and the G650ER about 7,500 nautical miles, making the G650ER best suited to the longest nonstop city pairs. Passenger capacity is broadly similar in typical executive layouts, but scales upward with cabin size: the G500 commonly carries about 12 to 16 passengers, the G600 about 13 to 17, and the G650ER often about 14 to 18 (with maximum certified seating higher depending on configuration).
