Cessna Citation X (750)

The Citation X (750) was, for years, the fastest civilian aircraft in the sky short of Concorde, cruising near Mach 0.92 thanks to its Rolls-Royce AE3007C engines. That speed is the aircraft’s whole reason for being, and it comes with a real tradeoff: higher fuel burn and operating costs than a midsize jet of similar cabin size, which owners should budget for explicitly rather than comparing this type directly against a Sovereign or Excel on a per-hour basis.

The Honeywell Primus 2000 avionics are mature and well-supported, and because the type has a loyal following among speed-focused owner-pilots and operators, there’s a solid, if somewhat specialized, base of maintenance expertise. Recurrent training requirements are also worth factoring in, since the aircraft’s performance envelope calls for pilots comfortable operating at the high end of the jet’s capability.

Resale demand for the Citation X tends to come from a narrower buyer pool than more common midsize types, since speed rather than cabin volume is the primary selling point, but that same niche appeal has kept the type in steady demand among owners who specifically want the fastest available option, which supports reasonably stable financing terms.
