Dassault Falcon 7X vs Gulfstream G550
The Matchup
Two of the best large-cabin jets ever built, now competing on the pre-owned market at increasingly attractive prices. The Falcon 7X brings tri-engine efficiency and unmatched airport access. The G550 brings more range, a longer cabin, and the deepest support network in large-cabin aviation. The acquisition market references below use dated research.
Head to Head
| Dassault Falcon 7X | Spec | Gulfstream G550 |
|---|---|---|
| 5,950 NM at Mach 0.80 | Range | ★6,750 NM at Mach 0.80 |
800 NM more range. That's the difference between needing a fuel stop and not on routes like Dubai to New York or London to Tokyo. The G550's range advantage is real and operationally significant. | ||
| Mach 0.90★ | Max Speed | Mach 0.885 |
Slightly faster, but neither aircraft is built for speed racing. The difference translates to maybe 10 minutes on a long sector. | ||
| 7 ft 8 in★ | Cabin Width | 7 ft 4 in |
Four inches wider. In a large-cabin jet, that's noticeable — especially in seat comfort and lie-flat bed width. | ||
| 39 ft 1 in | Cabin Length | ★43 ft 11 in |
Nearly 5 feet longer. The G550's cabin supports three generous zones; the 7X's three zones are tighter. For groups of 8+ passengers, this extra length matters. | ||
| 6 ft 2 in | Cabin Height | 6 ft 2 in |
| 12–16 | Passengers | ★12–18 |
More seating capacity reflects the longer cabin. | ||
| 51,000 ft | Ceiling | 51,000 ft |
| 5,710 ft★ | Takeoff Distance | 5,910 ft |
200 feet shorter takeoff. Combined with tri-engine climb performance, the 7X gets off the ground faster and steeper. | ||
| 2,260 ft★ | Landing Distance | 2,770 ft |
Over 500 feet shorter. This is where the Falcon's fly-by-wire and tri-engine design really show up. The 7X accesses London City, Lugano, Aspen, and Samedan. The G550 can't. | ||
| 3× Pratt & Whitney Canada PW307A (6,402 lbs each)★ | Engines | 2× Rolls-Royce BR710 (15,385 lbs each) |
The Falcon burns roughly 240 gal/hr vs the G550's 340 gal/hr — a 30% fuel efficiency advantage. Three engines to maintain, but significantly less fuel to buy. | ||
| $12.93M–$43.7M Vref (July 2026) | 2026 Acquisition Market Reference | $17M–$35M asking (Q3 2026) |

Falcon 7X
London City, Lugano, Samedan, Aspen, Cannes-Mandelieu — the 7X goes where the G550 can't. If your regular destinations include short or steep-approach airports, the Falcon is the clear winner.
Compare current aircraft offers
Market research reviewed October 8, 2026: Dassault Falcon 7X: $12.93M–$43.7M Vref (July 2026); Gulfstream G550: $17M–$35M asking (Q3 2026).

Aircraft age, condition and maintenance commitments can outweigh an apparent model-level price advantage.
Falcon 7X
30% less fuel burn. At 400 hours per year, that's $250K–$350K in annual fuel savings. The tri-engine configuration is genuinely more efficient.
G550
Five feet of additional cabin length makes a real difference with 10+ passengers. The G550's three zones are more generously proportioned.
G550
With 600+ aircraft built, the G550 has one of the most liquid pre-owned markets in aviation. The Falcon 7X (300+ built) is well-supported but has fewer comparable sales and a thinner market.
The Final Take
But the Falcon 7X earns its premium for operators who need airport access the G550 can't deliver. If you routinely fly into London City, Alpine airports, or other challenging fields, the 7X's short-field performance is worth every dollar. Add the fuel savings over a 10-year ownership cycle, and the Falcon's total cost of ownership can actually undercut the G550 despite higher acquisition costs. Buy the G550 for range and value. Buy the 7X for airport access and efficiency. Both are outstanding choices in the large-cabin pre-owned market. Market research reviewed October 8, 2026: Dassault Falcon 7X: $12.93M–$43.7M Vref (July 2026); Gulfstream G550: $17M–$35M asking (Q3 2026).
