The Citation XLS is a Citation Excel with increased payload, in addition to improved PW545B engines and range.
The 560XL Citation XLS combines a shortened Citation X cabin with a modified Citation V wing. Its two P&W PW 545B turbofan engines provide 330 nautical miles more range and a normal cruise speed 19 knots faster than the Citation Excel. The cabin provides comfortable seating for seven passengers.
Cessna introduced the Citation XLS+ in 2006. The XLS+ replaces the Honeywell Primus 1000 avionics suite with the Rockwell Collins Pro Line 21 Avionics Package. The engines have been improved and the XLS+ is equipped with two P&W 545C turbofan engines that now have FADEC installed.
