Introduced in mid-1976 and named in Japan Galant Σ (Sigma) third Galant was also offered in Europe in February 1977 under the name Mitsubishi Galant , while the station wagon was sold in North America as Dodge Colt. In Australia, where the model was assembled in a Chrysler plant, it ran under the name Chrysler Sigma.

This generation existed only as a four-door sedan and five-door station wagon. As a coupe variant of Mitsubishi Sapporo introduced in the fall of 1975 , which was called in Japan Galant (lambda) and in Australia Chrysler Scorpion.

The main technical feature of this series were the MCA jet engines with "Jet Valve", an additional intake valve per cylinder, which made it possible to reduce exhaust emissions without having to thoroughly rework the cylinder head, as well as the patented balance shafts to increase smoothness.
