Which Should You Buy: Dassault Falcon 8X or Gulfstream G650?

Bottom line: Choose the Falcon 8X for trijet efficiency and access — three engines, fly-by-wire control and the field performance to use demanding airports, with strong economy on long legs. Choose the G650 for speed and range — a faster, longer-legged flagship that set the ultra-long-range benchmark. On safety the Falcon's third engine adds an extra margin on oceanic crossings and out of hot, high or short runways, while the G650 brings twin-engine redundancy and a class-leading record — both excellent. Trijet efficiency and field access, or speed and range.

Pick the Falcon 8X if…

  • Lower operating cost — ~$4800/hr vs $5800/hr.
  • Newer design — production from 2016 vs 2012.

Pick the G650 if…

  • More seats — 19 vs 16.
  • Longer range — 7500 nm vs 6450 nm.
  • More inventory — 18 listings vs 7.

Frequently Asked Questions

What's the difference between the Falcon 8X and G650?
The 8X is a three-engine, fly-by-wire ultra-long-range jet known for efficiency and field performance; the G650 a twin that leads on speed and range. They differ in engine count, efficiency and outright reach.
Which has the longer range and is faster?
The G650 — faster and longer-legged, the class benchmark. The 8X is also intercontinental, trading some range for trijet efficiency and field access.
Why does the Falcon have three engines?
The trijet layout adds an engine-out margin on long over-water flights and improves performance from hot, high or short runways — a Dassault signature. The G650 achieves its mission on two.
Which is better, Dassault Falcon 8X or Gulfstream G650?
It depends on your mission and budget. The Falcon 8X cruises at 488 kts with 6,450 nm range. The G650 cruises at 488 kts with 7,500 nm range. Review the specs table above to find which fits your flying profile.
How do prices compare?
Prices vary by year, hours, avionics, and condition. Always get a pre-buy inspection.
What's the difference between Dassault Falcon 8X and Gulfstream G650?
Falcon 8X engine: Pratt & Whitney PW307D. Seats: 16 vs 19. Cruise: 488 vs 488 kts. Range: 6450 vs 7500 nm.
Which is cheaper to operate per hour?
Falcon 8X: about $4800/hr variable cost. G650: about $5800/hr variable cost. Variable cost includes fuel, reserves and overhaul accruals. Annual fixed costs (hangar, insurance, annual inspection) add to the total.
Which has more seats and useful load?
Falcon 8X: 16 seats / 20,000 lb useful load. G650: 19 seats / 30,000 lb useful load. Useful load = max gross weight minus empty weight; it determines how much fuel plus payload you can carry.
How does maintenance compare — TBO and overhaul cost?
Falcon 8X: 5,000-hour TBO, overhaul ~$1,200,000. G650: 6,000-hour TBO, overhaul ~$900,000. Reaching the time-between-overhaul (TBO) triggers a mandatory engine/airframe rebuild that affects resale value.
