The first year of production for the Dodge Charger was promising, with more than 30,000 orders. That would not last, however, as the Charger eventually fell out of favor by the mid-70s. Though the name lived on through, the true Charger had a life of 1966 - 1974. As one of the first mid-sized muscle cars, the 1966 Charger had more legroom than the competition, and boasted engines such as a standard 5.2-liter V8. There was also a 5.9-liter and a 6.3-liter engine that made 325-horsepower. There was also a 7.0-liter, 415-horsepower engine available. This was the HEMI, or hemispherical combustion chamber. The HEMI was discontinued in 1972.
