Mitsubishi Sigma: from Galant Sigma to Diamante-based saloon
Mitsubishi Sigma is the name given to various Mitsubishi models sold between 1976 and 1996. This article focuses mainly on the Sigma saloon and estate sold in Europe and Japan from 1991 to 1996, with a brief look at the earlier Galant Sigma.
Sigma in a nutshell
Up until the 1990s, the Sigma was a Galant-based version: known as the Galant Σ in Japan, Sigma (previously Chrysler Sigma) in Australia, and Galant Σ and later Sigma in North America.
From 1991 to 1996, the Sigma became an entirely different car—a larger Diamante-based saloon and estate sold in Japan and Europe. It was this model that was sold in Europe.
Generations — what’s the difference
Early Galant Sigmas (1976–1987) are classic Galant-based cars, of which there are virtually none in Lithuania.
The 1991–1996 Sigma features front-wheel drive, a V6 engine, and a comfortable interior. This car was also the basis for the Mitsubishi Magna produced in Australia.
Engines and gearboxes
The 1991–1996 Sigma most commonly has a 3.0-litre V6 petrol engine, with both 12- and 24-valve versions available. The most powerful 24-valve version produced around 200 hp.
Gearboxes come in manual or 4-speed automatic. Drive is to the front wheels.
What to check when buying a used Sigma
This is an old car, so the body condition is key: check for rust, wheel arches, door sills, and the boot floor.
In the case of a V6 engine, check if the timing belt has been changed on time, if there are no oil leaks, and if the engine runs smoothly. The automatic gearbox should shift without any jolts.
Look for used parts and mechanics in advance, as some components — body and interior — can be hard to find.
