Falcon 7X vs Gulfstream G650: Range, Cabin, Speed and Which to Buy
Dassault Falcon 7X vs Gulfstream G650: Performance and Market Comparison
Comparison · Ultra-long-range business jets
The Dassault Falcon 7X and the Gulfstream G650 are the two most compared ultra-long-range jets on the pre-owned market. The G650 flies farther, faster and has the larger cabin. The Falcon 7X is lighter, burns less fuel and uses three smaller engines, and it costs less to buy.
Both are out of production: Dassault built the 7X from 2005 to 2023, and Gulfstream completed the last G650 in February 2025. Every aircraft for sale today is pre-owned, so the choice comes down to missions, budget and the condition of each airframe.
Verdict
Short answer
Choose the Gulfstream G650 if
Gulfstream G650
You need 7,000 nm or more nonstop, the widest cabin of the two and the higher top speed, Mach 0.925.
Choose the Falcon 7X if
Dassault Falcon 7X
Your missions fit within 5,950 nm and you want a lower purchase price, less fuel on board and a lighter aircraft.
Specifications
Side by side
Gulfstream G650
Dassault Falcon 7X
RangeG650
The G650 flies 7,000 nm at Mach 0.85 and the G650ER 7,500 nm, against 5,950 nm for the Falcon 7X with 8 passengers. That extra 1,000 to 1,500 nm is the difference between nonstop and a fuel stop on routes such as Dubai to Los Angeles. For most city pairs under 5,900 nm, both aircraft fly nonstop.
CabinG650
The G650 cabin is 14.27 m long, 2.59 m wide and 1.96 m high, with room for up to four living areas. The Falcon 7X cabin is 11.91 m long, 2.34 m wide and 1.88 m high, typically in three areas. The G650 is about 2.4 m longer and 25 cm wider inside.
SpeedG650
The G650 has a maximum operating speed of Mach 0.925 and a high-speed cruise of Mach 0.90. The Falcon 7X tops out at Mach 0.90 and cruises long range at Mach 0.80. At long-range cruise the gap is Mach 0.85 for the G650 against Mach 0.80 for the 7X, which saves time on a ten-hour trip.
Weight, fuel and enginesFalcon 7X
The Falcon 7X weighs 31,751 kg at maximum takeoff and carries 14,488 kg of fuel; the G650 weighs 45,179 kg and carries 20,049 kg. Three PW307A engines of 6,402 lbf give the 7X less total thrust and lower fuel burn per hour. The trade-off: three engines mean three maintenance histories to check and fund.
Runway and airports
Close: 1,740 m balanced field length for the Falcon 7X and 1,786 m takeoff distance for the G650 at maximum weight, 1,920 m for the G650ER. The 7X lands in 631 m. Both reach 51,000 ft.
Flight deck and technology
The Falcon 7X was the first fully fly-by-wire business jet, with the Honeywell Primus Epic based EASy flight deck. The G650 followed as the second, with Gulfstream PlaneView II, also based on Primus Epic, four 14-inch displays and a head-up display with enhanced vision.
Market and price
Both fleets are closed: more than 280 Falcon 7Xs and more than 500 G650s. A G650 of the same year usually sells for more than a Falcon 7X. The successors are the Falcon 8X (6,450 nm) and the Gulfstream G800 (8,200 nm). ICCJET gives a current value for any aircraft on request.
