1973
The second-generation Galant—in sedan and GTO forms—was more widely exported and was sold in Australia as the Chrysler Valiant Galant and in Europe as the Colt Galant. This model was more curvaceous, influenced by coke-bottle styling, and featured a larger, 1850 cm³ engine, as well as a new 2·0 'Astron' unit developing 125 PS. It was also offered as the Dodge Colt in the US.
1976
The third-generation Galant, dating from 1976, was divided into two models: the Galant Sigma (for the sedan and wagon) and the Galant Lambda (the coupé). The former was sold in many markets as the Mitsubishi Galant (without the word 'Sigma') and in Australia as the Chrysler Sigma (until 1980, after which it became the Mitsubishi Sigma). Strangely, in New Zealand it was badged as 'Galant Sigma' but colloquially referred to as the 'Sigma', a name it formally adopted after 1980.
Sapporo
The coupé was sold in Europe as the Mitsubishi Sapporo, in Australia as the Chrysler (and later Mitsubishi) Sigma Scorpion, and in the United States as the Plymouth Sapporo and Dodge Challenger from 1978 to 1983.
