The Cessna Citation Model 560XL is member of the wide-ranging Citation brand of business jets, starting from the Excel and later evolving into the Citation XLS and then the Citation XLS+ models.
With the success of Cessna's Citation VII, the manufacturer saw a market for an aircraft with the Citation X's features but aimed at a more traditional market. Rather than being a direct variant of another Citation airframe, the Excel was a combination of technologies and designs.
To produce the Excel, Cessna took the X's wide, stand-up cabin fuselage, shortened it to about 21 feet (6.4 m) and mated it with an unswept wing utilizing a supercritical airfoil (based on the Citation V Ultra's wing) and the tail from the Citation V.
