The most telling feature was the headlight design, housed under heavily chromed lids typical of Dodge.

In 1957, the DeSoto Firesweep was powered by the Dodge "Poly" 325 V8 with a 2bbl Stromberg down draft carburetor.

The 325 was basically a detuned polyspherical combustion chambered version of the Dodge "Red Ram" 325 Hemi.

DeSoto offered a laundry list of options for the vehicle to include, but not limited to: clock, AM radio, rear speaker, air conditioning, carpeting, deluxe cloth seat inserts, dual rear antennae, deluxe interior lighting, stainless steel stone shields, power steering, and power brakes.

[6] The 1959 Firesweep, released in July 1959, was also assembled from CKD components,[7] and was equipped with a 361-cubic-inch V8 engine and a push-button automatic transmission.

[7] The Firesweep was replaced on the Australian market in 1960 by the locally produced Dodge Phoenix.
