Mitsubishi Sigma I (A120) gallery (1976–1980)
The Sigma I (A120) vehicle generation was manufactured by Mitsubishi Motors from 1976 to 1980 and offered in sedan, station wagon body configurations.
The first-generation Galant Sigma (A120 chassis) premiered in 1976 in sedan and wagon body styles. Engineering of the Sigma I (A120) (factory code A120) emphasized high structural rigidity, aerodynamic efficiency, and optimized interior spatial packaging. Built with reinforced body structures utilizing high-tensile steel alloys, the platform delivered reduced curb weight alongside improved occupant crash protection. The vehicle was distributed globally in multiple configuration packages designed to satisfy diverse market demands and regional regulatory specifications.

Powered by MCA-Jet 1.6L to 2.0L four-cylinder engines with twin Silent Shaft technology. The powertrain lineup incorporated efficient engine families paired with robust manual, automatic, or continuously variable transmissions depending on trim selection. Drivetrain engineering integrated advanced suspension tuning and traction management systems. Periodic mid-cycle cosmetic and technical updates refreshed front-end aesthetics, lighting technology, and cabin infotainment features, maintaining competitive positioning across international consumer segments throughout its production lifespan.
