The Mitsubishi Tredia was a subcompact sedan built by Mitsubishi Motors from 1982 to 1990. Its name is supposedly derived from Mitsubishi's "Three Diamonds" logo. Alongside the Cordia and Starion, it was one of the first cars imported and sold to America and Panama by the company without the involvement of its then partner, the Chrysler Corporation. In Japan, it was sold at a specific retail chain called Car Plaza.


Designed to fit between the existing Galant and Lancer models to increase the overall lineup of passenger vehicles, the Cordia and Tredia used front-wheel drive, and were similar in design to the contemporary Mirage. They incorporated a MacPherson strut/independent trailing arm suspension, front disc brakes, manual or electrically controlled automatic transmission, and a choice of three engines: a 1.4 L rated at 68 hp (51 kW), a 1.6 L rated at 74 hp (55 kW) and a 114 hp (85 kW) turbocharged 1.6 L, which was the first such engine to be sold in Japan. Some smaller export markets also received a carb-fed 2.0 L rated at 110 hp (82 kW).

The cars were given a mild facelift in 1983, and four-wheel drive was offered in 1984. The engine range was overhauled in 1985 to allow the cars to run on unleaded fuel, including the introduction of a 1.8 L engine in both 100 hp (70 kW) naturally aspirated and 135 hp (101 kW) turbocharged form, before production was discontinued in 1990.

The Tredia was assembled, alongside the Cordia with which it shared many 'under the skin' parts, in New Zealand by Todd Motors, later Mitsubishi New Zealand. The cars were imported as CKD kits and were built with about 40% local content including glass, upholstery, carpet, wiring harnesses and radiators. Both normally aspirated and turbocharged versions were made. All models were initially 1.6-litre but the normally aspirated model was later changed to a 1.8-litre engine at the same time as the original 4x2 'Supershift' manual transmission was changed to a conventional five-speed gearbox. Normally-aspirated models were also offered with a conventional three-speed automatic gearbox. In 1985 Todd's added an additional automatic-only 1.8SE trim version with two-tone paint, power windows and locks and four-speaker factory-fit audio system.
