1957 DeSoto Firedome III Four-Door Sedan Dimensions, Size & Specs

The 1957 DeSoto Firedome III weighs approximately 1794 kg (3954 lbs) curb weight. This weight is quite typical for large American sedans from the 1950s, reflecting the heavy steel construction and robust build quality. The relatively high weight contributes to a stable ride but also impacts fuel economy and performance.

The ground clearance of the 1957 DeSoto Firedome III is 137 mm (5.4 inches). This moderate ride height was designed to balance good handling and comfort on American roads, which often featured rough surfaces. It also helps protect the undercarriage while retaining a low, sleek profile for aerodynamics and aesthetics.

With a length of 5537 mm (about 18.16 feet), a width of 1986 mm (6.52 feet), and a height of 1448 mm (4.75 feet), the 1957 DeSoto Firedome III is relatively large compared to many modern vehicles. Standard single-car garages typically range from 2.44 to 3.05 meters (8 to 10 feet) wide and about 6 meters (20 feet) deep. The Firedome III's width at nearly 2 meters might be a tight fit but generally will fit width-wise; lengthwise it fits comfortably within a standard garage's depth. However, some tighter or narrower garages might pose challenges due to its broad width and door openings.

Compared to the previous DeSoto Firedome generation produced before 1956, the 1957 Firedome III was slightly larger in length and width. Earlier models typically measured around 5400 mm (213 inches) in length. The slight size increase contributed to improved interior space and road presence, reflecting a trend in the 1950s where manufacturers progressively increased vehicle dimensions to improve comfort and style.

The 1957 DeSoto Firedome III was designed as a full-size sedan, offering spacious interiors to comfortably accommodate up to six passengers, typical with a front bench and rear bench seating arrangement. The wide interior dimension provided generous legroom, shoulder room, and headroom, reinforced by its 1986 mm (78.2 inches) width. The car also featured upscale trim, quality materials, and options like power windows or seats in some trims, contributing to enhanced passenger comfort for its time.

When compared to contemporaries like the 1957 Chevrolet Bel Air or the 1957 Plymouth Savoy, the DeSoto Firedome III holds its own in size and stature. The Bel Air measured about 5550 mm (218.5 inches) in length and was slightly narrower, while the Plymouth Savoy was typically shorter around 5350 mm (210 inches). The DeSoto's broader width and substantial curb weight reflect its slightly more upscale positioning, offering a roomier and more solid feel compared to many competitors.

The 1957 DeSoto Firedome III is a full-size sedan, specifically offered as a four-door sedan in this generation. This body style was popular for family use and business purposes alike, combining passenger capacity, comfort, and practicality with the stylish and bold design elements of the late 1950s American automobiles.

The 1957 DeSoto Firedome III was commonly equipped with a V8 HEMI engine, part of Chrysler's renowned HEMI family. This engine delivered strong horsepower and torque for its time, providing smooth acceleration and respectable top speeds for a large sedan. The car's substantial curb weight of 1794 kg (3954 lbs) meant performance was balanced between power and comfort-oriented tuning.

The 1957 DeSoto Firedome III embodied the design ethos of the mid-1950s with its large dimensions, low roofline, and wide stance. Its size of 5537 mm length and 1986 mm width reflected the trend towards big, bold American cars boasting spacious interiors and road presence. Styling cues like prominent tailfins, chrome accents, and expansive glass areas made the Firedome III a visually striking sedan fitting well within mid-century motoring trends emphasizing luxury and style.
