The next step in the line of Cessna aircraft descending originally from the Citation II was the Citation Ultra, which was announced in the early 1990s. The Citation Ultra continued to improve on the Citation V with yet more powerful engines and upgraded avionics.
The Citation Ultra’s design was more focused on improving the cabin. It contained the same size cabin and baggage hold, and the same seating arrangement as the Citation V, with standard seating for seven and an eighth place available through use of the belted lavatory seat. The Citation Ultra also featured recessed tables and a full refreshment center.
