The Citation X+ is a high-speed super-midsize jet designed for travelers who place exceptional value on trip time. Its Mach 0.935 maximum operating capability, transcontinental range and stand-up cabin make it one of the most distinctive pre-owned business jets.

The Citation X+'s maximum range is 3,380 nautical miles — 660 nm less than the Embraer Praetor 600, the longest-legged Super Mid-Size Jet in our set.

Aircraft decision brief
Model overview
The X+ combines Rolls-Royce AE3007C2 engines, Garmin G5000 avionics and a 3,380-nautical-mile maximum-range profile. A typical eight-passenger layout sits within a 5-foot-7-inch-high cabin, and the aircraft can climb to 51,000 feet.
Production ended in 2018 after a short X+ run and more than two decades of combined Citation X-family production. The model remains compelling for speed-focused missions, but buyers should approach it as a specialized aircraft with a smaller fleet and higher operating demands than conventional midsize Citations.
Mission fit
Decision lens
Planning lens
Engine and APU coverage, inspection timing, parts planning and experienced maintenance support are especially important for the relatively small X+ fleet. Confirm the availability and cost of model-specific components before acquisition.
Runway requirements, fuel burn and operating complexity can exceed those of slower competitors. A mission analysis should determine whether time savings justify the acquisition and support profile.
Category context
The X+ is substantially faster than most super-midsize competitors, but newer aircraft such as the Citation Longitude, Challenger 350 and Gulfstream G280 offer wider or more modern cabins and different efficiency tradeoffs. The original Citation X is less expensive but lacks the X+ avionics, engine and cabin updates.
