The DeSoto Firedome was a full-size automobile produced between 1952 and 1959 by DeSoto automobiles, a division of the Chrysler Corporation. Introduced as DeSoto's premium line of vehicles in 1953 and 1954, the Firedome also occupied the least expensive position in the model lineup during 1955 and 1956model years before it was reclassified as a mid-range vehicle offered by DeSoto between 1957 and 1959.
Topline series, 1952–54
The 1953 Firedome was introduced just prior to DeSoto's 25th Anniversary in 1953, and arrived as the new top series, displacing the Custom nameplate which was retired at the end of the 1952 model year. The entire De Soto model lineup was restyled and Firedome prices started at US$2,740. During the 1953 model year, approximately 64,211 examples were produced. The Firedome could seat six passengers. It was available as a 4-door sedan, 5-door station wagon, 2-door coupe and 2-door convertible. The AM radio was $85. The Firedome was powered by a HemiV8 engine producing 160 hp and had a top speed of 100 mph. The car weighed 3,700 lb and had a 0–60 mph time of 15.5 seconds. This was the first time that DeSoto offered an 8-cylinder engine in one of its models since 1931. By 1953, DeSoto's Firedome Hemi V-8 produced 170 horsepower.
In 1955, Chrysler dropped its 6-cylinderDeSoto Powermaster series and added the topline Fireflite series, pushing the Firedome down to entry level status. Still, the Firedome was not a cheap offering, retaining its V8 engine, but increasing the 276 c.i. displacement to 291 c.i. with a larger bore,a power boost to 185 horsepower, and coming with a host of features and interior upgrades that were lacking in the Powermaster series. While Powerflite 2-speed automatics were advertised as optional transmission equipment on the Firedome, officially the car was also offered with a 3-speed manual as standard equipment, although few were produced. In 1956,the Firedome V-8 got still another boost in horsepower, to 230 H.P., an increase of 45 horsepower over the previous year.
Midline series 1957–59
The series was again moved upmarket in the model offering when the 1957 DeSotos were introduced, with the new entry-level Dodge-based Firesweep. A new air-conditioner was offered. By 1958 the horsepower had increased to over 300 with the option of the 361 cubic-inch V8 engine. Zero to 60 mph now took just under eight seconds with a top speed of. However 1958 DeSoto's sales skidded by almost 60% from 1957's model year output, partially due to the economy and partially because of build issues with the 1957 models. In an attempt to attract buyers, Chrysler offered the 1959 DeSoto Firedome in 26 solid colors and 190 two-tone finishes. By the end of the 1959 model year, Chrysler was struggling to find buyers for its DeSoto automobiles. Despite the wide variety of models available, consumers shunned DeSoto automobiles as rumor circulated that Chrysler would phase out the marque. A padded dash was standard. Firedome production ended at the end of the 1959 model year. For the 1960 model year DeSoto offered two models, the Fireflite and the Adventurer. For model year 1961, a model named only "DeSoto" was sold as a two-door hardtop and four-door hardtop. The end of the DeSoto marque came on November 30, 1960, 48 days after the 1961 models were introduced, ending 32 years of production.
