The Dodge Coronet is an automobile that was marketed as a full-size car in the 1950s, initially the division's highest trim line. The stock Dodge Coronet was a smooth running car, and the six-cylinder engine could power the car to 90 mph (145 km/h). A limited production model was a four-door, eight-passenger limousine, an extended version of the stock Dodge Coronet. One of the most notable features of the first generation Coronet was a three-speed, fluid-driven transmission that was operated by a foot pedal on the floor. It required no shifter. Production of the first generation Coronet lasted until 1952, when the Second Generation Dodge Coronet was introduced.
