Cessna Citation X+: The Complete Buyer's Guide
The Short Version
The Cessna Citation X+ held the title of fastest civilian aircraft from 2014 to 2025. It cruises at Mach 0.935 and covers 3,460 NM. Production ended in 2018. Pre-owned examples trade between $5M and $12M. Nothing in this price range comes close on speed.

Operational Reach
What Makes the Citation X+ Different
1. Mach 0.935 cruise speed
Nothing in its size or price class comes close. 10–12% faster than competitors, saving 30–45 minutes on a 4-hour flight.
2. 51,000 ft ceiling
FL510 — above the weather, above the traffic, in smooth air. Most super-midsize jets are limited to FL450.
3. Acquisition value
Pre-owned X+ models start at $5M. For the fastest civilian aircraft at this price point, remarkable value.
Who Is This Aircraft For?
- ●Speed-obsessed operators minimizing flight time above all else.
- ●High-frequency domestic travelers flying 1,500–3,000 NM multiple times per week.
- ●Operators who value high-altitude cruise at FL510.
- ●Value buyers seeking unique performance at an accessible price.
When It's Not the Right Fit
- ●The cabin at 5’6” wide and 5’8” tall is the Achilles heel. Passengers can’t stand upright. The Rolls-Royce engines are thirsty at high speed — fuel burn at Mach 0.935 is ~50% higher than at Mach 0.82.

The Pre-Owned Market Right Now
Market research reviewed October 8, 2026. Figures below retain their source dates and measurement basis.
Dated market benchmark, reviewed October 8, 2026: Duncan Aviation's July 2026 guide gives Citation X+ Vref valuations of $8.06M–$11.81M across its listed vintages. This is a model-wide valuation reference, not a reported transaction range or a current seller quote; the upper end for an in-production type can include very new aircraft.
The X+ is priced above the original Citation X in Duncan's July guide. Its appeal depends on the value of time saved on the intended routes, so a purchase decision should pair the higher capital requirement with realistic annual flying hours.
What to Watch For When Buying
1. AE3007C2 Engine Health
Capable but expensive. Overhaul costs $1M–$1.5M per engine. Ensure hourly program enrollment.
2. Citation X vs. X+ Distinction
The X+ (2014+) has Garmin G5000 avionics and Mach 0.935 (vs. 0.92). Major avionics upgrade.
3. Landing Distance Limitations
3,200 ft landing distance limits access to shorter runways. Verify your regular destinations.
4. Cabin Width Reality
At 5’6”, a deal-breaker for some. Experience it in person.
5. Fuel Cost Planning
At Mach 0.935, fuel premium is ~$500/hr vs. Mach 0.82. Budget accordingly.

|---|---|---|---|---|---|---|---|
| Bombardier Challenger 350 | 3,200 NM | Mach 0.83 | 7’2” | 28’5” | 8–10 | Discontinued (historical) | ~$12M (historical) |
| Gulfstream G280 | 3,600 NM | Mach 0.84 | 7’2” | 25’10” | 8–10 | ~$24.5M (historical) | ~$10M (historical) |

Cessna Citation Longitude
vs. Bombardier Challenger 350
Dramatically wider and more comfortable. The X+ is dramatically faster and cheaper. Comfort vs. speed.
vs. Gulfstream G280
Wider, more comfortable, more range. The X+ is faster and cheaper. Speed vs. comfort.
vs. Cessna Citation Longitude
The spiritual successor — wider cabin, modern avionics, but cruises at Mach 0.84 vs. 0.935.
