Which Should You Buy: Gulfstream G600 or Gulfstream G650?

Bottom line: Choose the G600 for the newest design and efficiency — a clean-sheet large-cabin Gulfstream with the Symmetry flight deck and strong, efficient range. Choose the G650 for ultra-long-range and cabin — more range and a larger cabin, the flagship that redefined the class. On safety both are two-crew large-cabin Gulfstreams with engine-out redundancy and excellent records; the difference is range and cabin size versus newest airframe, not safety. Newest clean-sheet, or ultra-long-range flagship.

Pick the G600 if…

  • Lower operating cost — ~$5200/hr vs $5800/hr.
  • Newer design — production from 2019 vs 2012.

Pick the G650 if…

  • Longer range — 7500 nm vs 6500 nm.
  • More inventory — 18 listings vs 7.

Which is cheaper to operate per hour?
G600: about $5200/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?
G600: 19 seats / 27,000 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?
G600: 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.
