Airbus Acj320 Neo vs Dassault Falcon 6x vs Dassault Falcon 8x vs Gulfstream G650er

By category, the Airbus ACJ320neo is a VIP airliner based on a single‑aisle commercial jet, optimized for cabin volume and customization rather than pure business‑jet performance. The Dassault Falcon 6X and 8X and the Gulfstream G650ER are purpose‑built large/ultra‑long‑range business jets, prioritizing nonstop intercontinental reach, high cruise efficiency, and access to more business‑aviation airports. On range, the ACJ320neo is typically quoted around 6,000 nautical miles depending on configuration, placing it in long‑range territory but generally below the very longest‑range business jets. The Falcon 6X is also long‑range at roughly 5,500 nautical miles, while the Falcon 8X extends further at about 6,450 nautical miles. The G650ER sits at the top end of this group for nonstop distance at about 7,500 nautical miles. On passenger capacity, the ACJ320neo can accommodate more people in airline-style layouts but is often configured for fewer, with expansive lounges and private rooms; typical VIP layouts commonly seat roughly 20–50+. The Falcon 6X, Falcon 8X, and G650ER typically carry around 12–16 passengers in executive configurations, with maximum certified seating higher but rarely used.
