Gulfstream G600 vs Gulfstream G500

Both the Gulfstream G500 and G600 are long-range, large-cabin business jets built on the same modern Gulfstream platform, with similar cockpit technology, high-speed cruise capability, and a focus on low cabin altitude and passenger comfort. In overall category, the G500 is typically positioned as the slightly smaller, long-range large-cabin option, while the G600 sits above it as the higher-capability, longer-range model in the same family. Range is the clearest separator. The G600 is designed to fly farther on typical long-range profiles, making it better suited to longer city pairs and more route flexibility with reserves. The G500 offers strong intercontinental reach as well, but it generally comes up shorter than the G600, particularly on the longest missions. Passenger capacity is broadly similar, since both are large-cabin aircraft, but the G600 commonly accommodates a few more passengers or allows more spacious layouts at comparable comfort levels. In typical corporate configurations, both are often set up for roughly a dozen to under twenty passengers, with the G600 tending toward the higher end depending on interior arrangement.
