Frequently Asked Questions
What's the key difference between the Citation X and Gulfstream G450?
Size and range. The Citation X (Model 750) is a large-cabin high-speed jet — Rolls-Royce AE3007C1 engines, up to nine seats, approximately 525 kt cruise, approximately 3,000 nm range. The Gulfstream G450 is a large-cabin ultra-long-range jet — Rolls-Royce TAY 611-8 engines, up to sixteen seats, approximately 500 kt cruise, approximately 4,350 nm range. The G450 is much larger and has dramatically more range; the Citation X matches its cruise speed.
Citation X or G450 — which large jet?
Buy the Citation X if ~3,000 nm range, nine seats, and the highest cruise speed in business aviation are the mission — at a significantly lower acquisition cost than the G450. Buy the G450 if transatlantic range (~4,350 nm), sixteen passengers, a much larger stand-up cabin, and Gulfstream's advanced avionics are the requirements. The G450 is a fundamentally larger aircraft for true ultra-long-range operations.
How does the range difference matter?
The G450's ~4,350 nm range covers transatlantic routes non-stop. The Citation X's ~3,000 nm covers US transcontinental and many transatlantic routes with a fuel stop. For operations that must be non-stop transatlantic, the G450 is the correct aircraft; for US domestic and shorter transatlantic, the Citation X covers the mission.
How do the cabins compare?
The G450's cabin is substantially larger — sixteen seats in a stand-up, full-walk cabin with galley and lavatory in configurations suitable for long international flights. The Citation X's cabin accommodates nine passengers comfortably for shorter missions. For truly long-range international travel in executive comfort, the G450's cabin standard is the appropriate choice.
How do specs compare?
Citation X: two Rolls-Royce AE3007C1, up to nine seats, ~525 kt, ~3,000 nm. G450: two Rolls-Royce TAY 611-8, up to sixteen seats, ~500 kt, ~4,350 nm.
Which should I buy?
Citation X for US transcontinental and regional international missions at the highest speed, with nine seats — a capable large-cabin aircraft at a fraction of the G450's acquisition cost. G450 for true transatlantic and ultra-long-range international operations with sixteen passengers in a full executive cabin. The buyer who needs the G450 knows it; the Citation X serves those whose range requirement is under 3,000 nm.
Which is better, Cessna Citation X or Gulfstream G450?
It depends on your mission and budget.
The Citation X cruises at 480 kts with 3,070 nm range.
The G450 cruises at 476 kts with 4,350 nm range.
Review the specs table above to find which fits your flying profile.
How do prices compare?
Gulfstream G450: from $9,950,000.
Prices vary by year, hours, avionics, and condition. Always get a pre-buy inspection.
What's the difference between Cessna Citation X and Gulfstream G450?
Citation X engine: ROLLS-ROYCE AE3007C.
Seats: 12 vs 16.
Cruise: 480 vs 476 kts.
Range: 3070 vs 4350 nm.
Which is cheaper to operate per hour?
Citation X: about $3800/hr variable cost.
G450: about $3600/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?
Citation X: 12 seats / 6,800 lb useful load.
G450: 16 seats / 22,000 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?
Citation X: 5,000-hour TBO, overhaul ~$600,000.
G450: 6,000-hour TBO, overhaul ~$700,000.
Reaching the time-between-overhaul (TBO) triggers a mandatory engine/airframe rebuild that affects resale value.
