Airbus Acj Twotwenty vs Dassault Falcon 6x vs Dassault Falcon 8x vs Gulfstream G650er

By category, the Airbus ACJ TwoTwenty is a “bizliner” based on an airliner platform, optimized for spacious cabin volume and flexible interior zones, while the Dassault Falcon 6X and 8X are large-cabin long-range business jets, and the Gulfstream G650ER is an ultra-long-range flagship business jet focused on speed and range. On range, the G650ER typically leads at about 7,500 nautical miles, making it the strongest option for the longest nonstop city pairs. The Falcon 8X is close behind at roughly 6,450 nautical miles, offering very long reach with three-engine redundancy. The Falcon 6X is slightly shorter-range at about 5,500 nautical miles but still firmly intercontinental. The ACJ TwoTwenty is generally around 5,650 nautical miles, competitive with the 6X for many missions but with a different emphasis: cabin space over maximum range. On passenger capacity, the ACJ TwoTwenty carries the most in typical corporate layouts—often around 18 to 22 passengers—thanks to its wide, airliner-derived cabin. The Falcon 6X and 8X usually seat about 12 to 16, while the G650ER commonly accommodates roughly 14 to 19 depending on configuration.
