Falcon 7X vs Falcon 8X — generation comparison
The Falcon 8X entered service in late 2016 as Dassault's direct successor to the Falcon 7X. Both share the distinctive three-engine architecture and broad commonality of systems, but the 8X is a genuinely improved aircraft — not a marketing refresh.
What changed
Cabin. The 8X cabin is 42 inches longer than the 7X — Dassault stretched the fuselage between the wing and the aft pressure bulkhead, adding a full additional living zone.
Range. 8X carries 500 nm more — 6,450 nm vs 5,950 nm at Mach 0.80 with eight passengers. That brings city pairs like Beijing-New York and Sao Paulo-Moscow into reach without a technical stop.
Fuel efficiency. The PW307D engines on the 8X are roughly 7% more fuel efficient than the PW307A on the 7X. Combined with revised wing aerodynamics, real-world block fuel for equivalent mission length is 8–10% lower.
Avionics. 8X ships with EASy III; many 7X aircraft remain on EASy II (some upgraded). Difference is incremental — synthetic vision, FalconEye combined vision system, and improved CPDLC on EASy III.
What stayed the same
Three-engine PW307 architecture, fly-by-wire flight controls, certification basis, cockpit layout, and most cabin systems carry across from the 7X. A 7X-current pilot can transition to the 8X in a short differences course, not full type training.
Asking price spread (2026)
| Spec | Year band | Typical asking |
|---|---|---|
| Falcon 7X | 2007–2010 | $14M–$18M |
| Falcon 7X | 2011–2015 | $19M–$23M |
| Falcon 7X | 2016–2020 | $24M–$28M |
| Falcon 8X | 2016–2019 | $34M–$40M |
| Falcon 8X | 2020–2023 | $42M–$52M |
A late-build 7X and an early-build 8X overlap by year but sit $10–15M apart on price.
Operating cost
Indicative direct operating cost at 350 annual hours:
- Falcon 7X: ~$5,600 per hour
- Falcon 8X: ~$5,700 per hour
The 8X carries marginally higher fixed costs offset by better fuel economy. Effectively a wash hour-for-hour.
Which should you buy?
- If cabin length matters — regular four-place conferences, longer aft suite — the 8X is the right aircraft
- If the mission tops out at transatlantic and cabin volume is sufficient at 7X spec, the 7X delivers excellent value at a substantial capital discount
- If you want the newest available three-engine Falcon, the 8X is the only option — the 7X went out of production in 2020
Dassault's three-engine programme is unique in the long-range segment. Buyers prioritising engine redundancy on oceanic routes have no twin-engine equivalent.
