Dassault Falcon 6x vs Dassault Falcon 8x vs Gulfstream G650er vs Gulfstream G700

In category, the Dassault Falcon 6X and Gulfstream G700 sit in the large-cabin, ultra–long-range segment, while the Dassault Falcon 8X and Gulfstream G650ER are more squarely ultra–long-range flagships, with the G700 emphasizing maximum cabin volume and newest-generation systems. For range, the Falcon 6X is typically quoted around 5,500 nautical miles, making it a true long-range aircraft but shorter-legged than the others. The Falcon 8X extends that to about 6,450 nautical miles. Gulfstream’s G650ER reaches roughly 7,500 nautical miles, and the G700 is quoted at about 7,750 nautical miles, giving it the longest published range of the group. For passenger capacity, typical configurations across all four are commonly in the low-to-mid teens. The Falcon 6X and 8X are often arranged for about 12–16 passengers (maximums higher depending on layout), while the G650ER and G700 are similarly usually 13–17 in typical layouts, with the G700 often positioned for larger, more flexible cabin zoning at comparable loads.
