The Private Jet category encompasses a wide variety of aircraft, of many different sizes and capabilities ranging from aircraft optimized for relatively short-range regional travel, to large cabin aircraft able to traverse entire continents and oceans. These aircraft are manufactured by worldwide companies including Beechcraft, Bombardier, Cessna, Dassault Aviation, Embraer, Gulfstream, Hawker, Learjet, and Pilatus. Additionally, Airbus and Boeing build exclusive, private variants of many of the same aircraft operated by commercial airlines throughout the world.
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.
