The The Citation X will climb to 43,000 feet in just 30 minutes at its maximum takeoff weight, lifting you swiftly to transcontinental and transatlantic crossing altitudes. And the Citation X is certified to fly as high as 51,000 feet - where fuel efficiency is optimized and airline traffic is nonexistent.
At 600 mph, the Citation X will run the mile in a sizzling six seconds. It covers 3,300 nautical miles in less time than any other business jet. It streaks from LA to New York in under four hours. And it shrinks the New York-to-London flight to under six hours.

The Citation X can cross half a dozen time zones without a refueling stop. It combines cruising speeds of Mach .92 with true intercontinental and transatlantic range. The Citation X is no conventional aircraft. No other business aircraft in the world flies so far, so fast, on so little.
It doesn't feel like a midsized business jet inside. That's because it isn't. The Citation X opens up a whole new aircraft category - with the most spacious and stunningly attractive cabin ever created for a Citation.
