The third generation Dodge Charger was introduced for the 1971 model year. Chrysler's B platform was modified to meet new emissions and safety regulations. Available in six different packages with cosmetic changes that include: a split grill, semi fastback rear window, and a ducktail spoiler. The 1973 and 1974 Chargers were very similar to the 1971 with minor differences in the grill and headlamps. The increase in sales was mostly due to the elimination of the Dodge Coronet, which meant Dodge offered the two-door intermediate-size body style only as the Charger. Production of the third generation ended in 1974 with the introduction of the Fourth Generation Dodge Charger.
