Gulfstream G400 vs Gulfstream G500 vs Gulfstream G650er

The Gulfstream G400 is the newest and smallest of the three in overall capability, positioned as a large-cabin business jet with a focus on efficient transcontinental missions rather than ultra-long-haul flying. Its published range is about 4,200 nautical miles, and it typically seats up to around 12 passengers in a comfortable executive layout. The Gulfstream G500 sits a tier above as a long-range, large-cabin jet suited to longer intercontinental routes. It offers a published range of about 5,300 nautical miles and is commonly configured for roughly 12 to 14 passengers, balancing space, speed, and mission flexibility. The Gulfstream G650ER is the flagship ultra-long-range option in this comparison, built for the longest nonstop city pairs with a significantly larger cabin and higher long-haul capability. Its published range is about 7,500 nautical miles, and typical executive configurations seat about 14 to 18 passengers, with higher-density layouts possible.
