In the early 1990s, the company introduced its first full-size buses, the EMC 1st Premier conventional (EMC=Enterprises Michel Corbeil), using an International 3800 chassis (with Ford B800 as an option). In 1993, the EMC3900 was introduced; sharing its International 3900 chassis with the AmTran Genesis, the EMC3900 was a front-engine transit-style bus. For the United States bus market, Corbeil concentrated on its small bus offerings, not selling the 1st Premier or the EMC3900 outside of Canada. For 1994, Corbeil entered a joint venture with Indiana-based manufacturer Carpenter, manufacturing single rear-wheel buses marketed through its deal network (similar to a joint venture between Blue Bird and Girardin); the joint venture lasted through 1998.
