Which Should You Buy: Dassault Falcon 7X or Gulfstream G650?

Bottom line: Choose the Falcon 7X for trijet efficiency and flexibility — three engines, fly-by-wire control and the field performance to use hot, high and shorter runways, with strong fuel economy. Choose the G650 for speed and range — a faster, longer-legged flagship that redefined ultra-long-range travel. On safety the Falcon's third engine adds an extra margin on oceanic legs and out of demanding airports, while the G650 brings twin-engine redundancy and a class-leading record — both excellent, different approaches. Trijet efficiency and field access, or speed and range.

Pick the Falcon 7X if…

  • Lower operating cost — ~$4500/hr vs $5800/hr.
  • More inventory — 27 listings vs 18.

Pick the G650 if…

  • More seats — 19 vs 16.
  • Faster cruise — 488 kts vs 459 kts.
  • Longer range — 7500 nm vs 5950 nm.
  • Newer design — production from 2012 vs 2007.

Frequently Asked Questions

What's the difference between the Falcon 7X and G650?
The 7X is a three-engine, fly-by-wire 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, a class-defining ultra-long-range jet. The 7X 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 hot-and-high and short-field performance — a Dassault signature. The G650 achieves its mission on two.
Which is better, Dassault Falcon 7X or Gulfstream G650?
It depends on your mission and budget. The Falcon 7X cruises at 459 kts with 5,950 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 7X and Gulfstream G650?
Falcon 7X engine: Pratt & Whitney Canada PW307A. Seats: 16 vs 19. Cruise: 459 vs 488 kts. Range: 5950 vs 7500 nm.
Which is cheaper to operate per hour?
Falcon 7X: about $4500/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 7X: 16 seats / 18,000 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 7X: 6,000-hour TBO, overhaul ~$800,000. G650: 6,000-hour TBO, overhaul ~$900,000. Reaching the time-between-overhaul (TBO) triggers a mandatory engine/airframe rebuild that affects resale value.
