were, in effect, "underdrives"—consequently marked on the second shift lever as a "power" mode due to increased performance granted by the lower gearing. In contrast, the higher overdrive setting was noted as "economy". Mitsubishi called this a unique selling proposition. Facelift In February 1982, Mitsubishi facelifted the Mirage range. Distinguished by the installation of flusher fitting headlamps that extended into the fender panels, stylists also designed a new grille insert. The tail lights were larger, new firmer engine and transmission mounts were fitted, and a new, lighter and more rigid transmission case was developed. The dashboard was also updated, with rotating "satellite" buttons mounted within fingertip reach for light and wiper functions. Another new version for the Japanese market was the 1600SX, a well-equipped five-door automatic fitted with the 1600GT's 88-PS engine. 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. A more sporting turbocharged version of the 1.4-liter engine was made available in Japan from the time of the facelift as the 1400 GT Turbo, originally only in the three-door hatchback. To handle the additional power, the suspension was made firmer, the brake servo was upgraded, and the driveshaft was changed to an equal-length design featuring a central bearing. The small turbocharger, of Mitsubishi's own manufacture, unusually sat between the intake and the twin-barrel carburetor. The engine was equipped with a knock sensor, enabling it to run on petrols of various octane
