Gulfstream G500 vs Gulfstream G800

The Gulfstream G500 and Gulfstream G800 sit in different segments of Gulfstream’s large-cabin lineup. The G500 is best described as a long-range, large-cabin business jet designed for efficient intercontinental missions with a balance of speed, cabin comfort, and operating flexibility. The G800 is a flagship ultra-long-range large-cabin aircraft aimed at the longest nonstop city-pairs, prioritizing maximum range while maintaining a similarly premium cabin experience. In range, the G800 is substantially longer-legged, offering roughly 8,000 nautical miles, while the G500 is around 5,300 nautical miles (both figures commonly quoted at typical long-range cruise and standard reserves). This makes the G800 better suited to nonstop missions such as very long transoceanic routes that would typically require a fuel stop in a G500. For passenger capacity, both can be configured for similar maximum counts in the high teens (often up to about 19), but typical layouts differ: the G500 is commonly arranged for about 12 to 14 passengers, while the G800 is often configured for about 13 to 16, with more flexibility to add additional living zones for longer flights.
