Dassault Falcon 6x vs Dassault Falcon 8x vs Gulfstream G500

The Dassault Falcon 6X, Falcon 8X, and Gulfstream G500 all sit in the long-range, large-cabin business jet category, but they emphasize slightly different missions. The Falcon 6X is best viewed as a large-cabin, long-range jet aimed at transcontinental and many intercontinental trips, with a published range of about 5,500 nautical miles and a typical passenger load around 12 to 16 (maximum generally cited near 19). The Falcon 8X is the longer-legged flagship of the pair, positioned as an ultra-long-range large-cabin jet, offering roughly 6,450 nautical miles of range and a similar typical cabin count of about 12 to 16 passengers (with comparable maximum figures around 19). The Gulfstream G500 is also a large-cabin, long-range aircraft, typically quoted around 5,300 nautical miles of range, and commonly configured for about 12 to 16 passengers (maximum usually around 19). In short, the 8X leads on range, while the 6X and G500 are closer peers, with broadly similar passenger capacity.
