Bombardier’s Challenger family represents two distinct approaches to business aviation excellence. The Challenger 350 (super-midsize) and the Challenger 650 (large cabin) each offer compelling advantages, catering to different mission profiles and passenger requirements. While both are renowned for their reliability, comfort, and performance, understanding their differences is essential for making an informed decision.
Overview and Historical Context
Bombardier Challenger 350: The Super-Midsize Leader
The Challenger 350 first flew in March 2013 and was unveiled at the European Business Aviation Convention & Exhibition (EBACE) shortly thereafter. It received Transport Canada and FAA certification in June 2014, followed by EASA certification in September 2014. As an upgraded variant of the successful Challenger 300, the 350 features greater engine thrust, new canted winglets, a refined interior with 20% larger windows, and advanced avionics. By May 2020, a total of 355 Challenger 350 business jets had been built.
Bombardier Challenger 650: The Large Cabin Evolution
The Challenger 650 represents the latest evolution of the CL-600 platform, which began with the Challenger 600 in 1980. The 604 was introduced in 1995 with more powerful engines and structural improvements, followed by the 605 in 2005 with avionics and structural upgrades. The Challenger 650 was first announced at NBAA in 2014, with NetJets serving as the launch customer. It entered service in 2015 and features upgraded GE CF34-3B engines, two additional executive seats (accommodating up to 12 passengers), and larger galley appliances for faster meal preparation. A total of 158 Challenger 650 aircraft have been built.
