Archived side-by-side comparison from the Freestream library
This comparison covers three out-of-production business jets that occupied distinct positions within the super-midsize and upper-midsize segment during their respective production runs. The Bombardier Challenger 300, Cessna Citation Sovereign, and Cessna Citation X each addressed different priorities: wide-cabin comfort, transcontinental range, and high cruise speed respectively.
All three aircraft have completed their production cycles and remain in active secondary-market circulation. The data presented is drawn from Conklin & de Decker (JSSI) using standardised assumptions and reflects each aircraft's published type specifications. Acquisition cost is excluded by design.
The Challenger 300 is a super-midsize twin-engine business jet produced by Bombardier from 2001 to 2014, powered by two Honeywell HTF7000 engines and equipped with the Rockwell Collins Pro Line 21 avionics suite. With a maximum cruise speed of 470 knots and a seats-full range of 3,065 nautical miles, it offered intercontinental reach within a wide-body fuselage measuring 23.7 feet in length, 7.17 feet wide, and 6.08 feet tall. A total of 457 aircraft were produced, with 446 in service at time of publication.

The Citation X was the fastest civil aircraft in production during much of its commercial life, powered by two Rolls-Royce AE 3007C1 engines and reaching a maximum cruise speed of 525 knots at a certified ceiling of 51,000 feet. Produced by Cessna from 1993 to 2012, it carried up to eight passengers over a seats-full range of 2,890 nautical miles in a cabin measuring 23.75 feet in length. Avionics were supplied by Honeywell in the Primus Elite suite.
