The DeSoto Firesweep was an American automobile produced by DeSoto, a division of Chrysler, from 1957 to 1959. Positioned as the entry-level model in the DeSoto lineup, the Firesweep featured a full-size car design but was distinguished by using the shorter Dodge chassis, resulting in different size dimensions compared to other DeSoto models. It combined stylish mid-century design cues with Chrysler's reliable V8 powertrains. Throughout its brief production, the Firesweep saw two generations with minor design updates, maintaining its appeal during the late 1950s era of automotive innovation.
