Dassault Falcon 10x vs Dassault Falcon 8x vs Gulfstream G800 1"

The Dassault Falcon 10X is positioned as Dassault’s largest and longest‑range business jet, aiming at the ultra‑long‑range flagship category with an intended range of about 7,500 nautical miles and typically accommodating around 12–16 passengers depending on layout. The Dassault Falcon 8X sits in the long‑range large‑cabin class below it, offering roughly 6,450 nautical miles of range and commonly seating about 12–14 passengers in executive configurations. The Gulfstream G800 is in the ultra‑long‑range flagship segment and is generally the range leader among the three, advertised at about 8,000 nautical miles, with typical passenger capacity similar to its peers at roughly 12–19 depending on cabin arrangement. In short, the 8X is the smaller long‑range option, the 10X is Dassault’s step up into the top‑tier ultra‑long‑range bracket, and the G800 competes at the very top end with the longest published range and a comparably flexible cabin capacity.
