Dassault Falcon 8X for sale: More Range, Three Engines / Range: 6,450 nm / Passengers: Up to 16.
The Falcon 8X has a modest range advantage over the Global 6000 and uses three Pratt & Whitney PW307D engines. Dassault also places strong emphasis on its short-field capability. That can matter if your operation includes airports where runway performance is a bigger concern.
Gulfstream G600 for sale: The Newer Generation / Range: 6,600 nm / Cruise: Mach 0.85; high-speed cruise up to Mach 0.90.
The G600 moves the comparison into a newer generation of Gulfstream aircraft. Its published range is higher than the Global 6000, and it features the Gulfstream Symmetry Flight Deck. For a buyer who wants newer technology and is comfortable with the higher acquisition cost of a newer aircraft, the G600 deserves a direct comparison.
Bombardier Global 5000 for sale: Same Family, Shorter Range / Range: 5,200 nm / Cabin length: 40.7 ft (12.41 m).
The Global 5000 shares much of the Global 6000's basic design philosophy, including its wide cabin and two-engine layout. The main difference is range. If 5,200 nm covers the majority of your missions, the 5000 can be a sensible alternative. If 6,000 nm is important, the Global 6000 has a clear advantage.
Dassault Falcon 900LX for sale: A Different Mission Profile / Range: 4,750 nm / Passengers: Up to 14, depending on configuration.
The Falcon 900LX sits below the Global 6000 in range, but its three-engine layout and strong runway performance give it a different operating profile. It is worth considering when 4,750 nm is enough and airport access matters more than maximum range. For longer intercontinental missions, the Global 6000 has substantially more range.
