Dodge Challenger - Second generation (1978–1983)
The Challenger name was revived in late 1977 for the 1978 model year for a version of the early Mitsubishi Galant Lambda coupe. It was known overseas as the Mitsubishi Sapporo/Scorpion and sold through Dodge dealers as a captive import, originally as the “Dodge Colt Challenger”.[21]
It was identical except in color and minor trim to the Plymouth Sapporo with the Dodge version emphasizing sportiness, with bright colors and tape stripes, while the Plymouth emphasized luxury, with more subdued trim.
The cars were slightly restyled in 1981 with revised headlights and other minor cosmetic changes. Both cars were sold until 1983, until being replaced by the Conquest and Daytona.
