The Mirada replaced the Magnum for 1980 and was cousin to the redesigned Chrysler Cordoba. This new Dodge was on the J-body platform. The wheelbase was 112.7 inches and the overall length was 209.5 inches. Its curb weight was about 3450 lbs.
The standard body style was a 2-door coupe, but several variants were based on it. Optional was a power sunroof, or the buyer could get t-tops. A vinyl roof treatment known as Landau was an option. A convertible-look roof known as Cabriolet was offered too.
Three trim levels were offered the first year. They were the base Mirada, Mirada S, and the sporty Mirada CMX. An add-on group known as the Sport Handling pkg was also offered, which of course, made the car a better handling machine.
For engines, three choices were offered. Standard was a 225 CID 1bbl S6 that delivered 90hp and 160 ft/lbs of torque. First on the option chain was a 318 CID 2bbl V8 that delivered 120hp and 245 ft/lbs of torque. The top option was a 360 CID 4bbl V8 that delivered 185hp and 275 ft/lbs of torque, but only in the CMX version. The first two were shifted with a 3-speed 904 automatic, while the latter was shifted by a 3-speed 727 automatic.
In 1982, the sunroof option was dropped. In 1983, the T-tops and Landau body mods were dropped, leaving just the basic 2-door and Cabriolet body styles. It was also the final call for the Mirada nameplate. On a side note there were Miradas racing in NASCAR from the get-go.
