Mitsubishi Minica - Fourth Generation

Fourth Generation

In June 1977 the car and engine grew once again, creating the Minica Ami 55. While the side body panels remained the same, length increased yet a little more (3175 mm) and the entire car was widened by 10 mm (0.4 in). The updated 546 cc Vulcan 2G23 engine provided 31 PS (23 kW) for the A105A. Its sibling, the Minica 55 Van (A105V) was updated in March 1977 and was almost impossible to distinguish from the previous Minica 5 Van, aside from badging and a slightly less plasticky front end. The bigger engine provided some useful additional torque, but the sporting Minicas of the early seventies were now but a memory. For the time being, the traditional (and unusual amongst Kei cars) Panhard layout remained.

September 1978 brought another engine upgrade: The new "Vulcan II" G23B featured the lean burn MCA-Jet emissions control system with a hemispherical head, aluminium rocker arms and three valves per cylinder, but power outputs remained static. The model code became A106/106V.

In September 1981 the car received another redesign. An entire new rear end meant a slightly longer wheelbase (up to 2,050 mm) and a somewhat longer and taller body. The somewhat boxy rear end, still with a clamshell rear window, looked a bit incongruous paired with the original Minica F4 front wings and doors. The new Minica was renamed the Minica Ami L (A107A), but bigger news was that the Minica 55 Van, based on the 1969 A100V, was finally retired. The new A107V Minica Econo ("Econo" hinting at its primary use as a private economy car rather than as a commercial vehicle) looked very similar to the Ami L but featured a proper rear hatch and folding rear seat, allowing it to be registered as a light commercial vehicle like its competitors the Daihatsu Mira, Suzuki Alto and Subaru Rex. Cargo capacity, compared to the more workmanlike Minica 55 Van, was reduced from 300 to 200 kg (441 lb). A 2-speed, semi-automatic gearbox was also available on all models, while the standard four-speed manual received lower gearing for the Econo model. The engine was more quiet than before, featuring a milder cam profile. Power output of the G23B remained the same, although the Econo was stuck with a 29 PS (21 kW) version of the old 2G23 engine. Top speed of the Ami was 110 km/h (68 mph). In December 1981 a strict two-seater version of the Econo was added.

One year later, the Minica was sold with the new "MMC" logo rather than the old "three diamonds". In March 1983 the Minica Ami L Turbo became the first kei car to be offered with a turbocharger, offering 39 PS (29 kW) and glitzy graphics. This proved short-lived, as by January 1984 production of the A107 Minicas had ended, with Mitsubishi preparing for the release of an all new, front-wheel drive Minica.
