The Bombardier Challenger 350 and Cessna Citation Sovereign+ represent two distinct approaches to the midsize and super-midsize category. The Challenger 350 is powered by Honeywell HTF7350 engines and provides a wide-body cross-section cabin — 7.2 ft wide and 6.0 ft tall — with a range of 3,277 nautical miles. The Sovereign+ is a refined variant of the Citation Sovereign, certificated in 2013 and powered by Pratt & Whitney Canada PW306D engines with the Garmin G5000 avionics suite, delivering 2,773 nautical miles seats-full.
The Challenger 350 entered service in 2014 and production ended in 2022, succeeded by the Challenger 3500. The Sovereign+ was produced from 2012 to 2021. This archived comparison uses Conklin & de Decker data pulled 27 May 2026. Note that the Challenger 350 C&D record omits certain fields recorded for the Sovereign+; those cells are shown as available on request.
