At the same time as this facelift, Mitsubishi introduced a four-door sedan variant to Japan under the names Mirage Saloon and Lancer Fiore, which is not to be confused with the unrelated regular Lancer. The Fiore was often abbreviated to Lancer or Lancer F in international markets, eschewing the "Fiore" suffix. The sedan's backseat folded in a 60/40 split, just as for the hatchback. With Mirage hatchback and sedan sales in Japan restricted to the "Car Plaza" dealerships, the Fiore was intended to duplicate the Mirage's success at the "Galant Shop" — Mitsubishi's second retail sales channel. Lancer Fiore received the same 1.2- and 1.4-liter engines, and as a Mirage-derived model line, was substantially smaller than the strict Lancer. Apart from the wider axle track dictated by the switch to front-wheel drive, the original 1973-era Lancer offered a similar dimensional footprint. Unique to the four-door saloons was Mitsubishi's new "Modulated Displacement" (MD) engine, a short-lived technology which allowed the engine to run on only two cylinders while under light loads so as to save on petrol.
