To maintain a technological edge on the highly competitive market for regional airliners during the 1990s, several modifications and improved versions of the ATR 42 were progressively introduced. The initial ATR 42-300 model remained in production until 1996, while the first upgraded (and broadly similar) model, designated as the 'ATR 42-320, was also produced until 1996. The -320 variant principally differed in that it was powered by a pair of the more-powerful PW121 engines, giving it improved performance over the 300. Another variant, the ATR 42-300QC, was a dedicated [[combi aircraft|quick-change]] (convertible) freight/passenger version of the standard -300 series.<ref name="stats41">{{cite web |url=http://www.airliners.net/aircraft-data/stats.main?id=41 |title=ATR ATR-42 |publisher= Airliners.net |access-date=26 December 2014}}</ref><ref name="milestones arch" />
