Manufactured by Canadian aerospace firm Bombardier, the Challenger name encompasses a family of aircraft billed as “the best-selling business jet platform of the last decade.” All Challenger jets feature fuel-efficient turbofan engines, true “walk-about” cabins, and a supercritical wing design offering impressive climb and cruise performance at lower thrust settings.
Though the early Lockheed Jetstar had four, most production business jets have two jet engines, mostly rear-mounted podded engine. If mounted below their low wing, it wouldn't allow sufficient engine clearance without a too long landing gear. The HondaJet is the exception with its over the wing engine pods. Dassault Falcon still builds three-engine models derived from the Falcon 50, and the very light jet market has seen several single-engine design concepts and the introduction of the Cirrus Vision SF50 in 2016.
