The Panhard Dyna X was a lightweight berline designed by the engineer Jean Albert Grégoire. It was produced between 1948 and 1954, with a total of 47,049 units built. The car was offered in several body styles, including 4-door berline, 3-door estate, 2-door cabriolet, and light van. The Dyna X was powered by a front-mounted, front-wheel-drive engine, with a displacement ranging from 610 cc to 851 cc. The names Dyna 110, Dyna 120, and Dyna 130 represented the cars progressively increasing maximum speeds (in kilometers per hour), as engine power and size increased during the production run. The Dyna X berline was replaced by the larger Panhard Dyna Z in 1954.
