1958 DeSoto Firesweep I 2-Door Sportsman (facelift 1958) Dimensions, Size & Specs

The 1958 DeSoto Firesweep I 2-Door Sportsman weighs approximately 1749 kg (3855 lbs) curb weight. This relatively hefty weight is common for large American coupes of the era, influenced by substantial steel construction and luxury features. The weight offers a stable ride on highways but may result in slower acceleration and less nimble handling compared to lighter vehicles. Nevertheless, it provides a solid and comfortable driving experience typical of the late 1950s automotive design.

With a length of 5499 mm (216.4 inches), width of 1989 mm (78.3 inches), and height of 1443 mm (56.8 inches), the 1958 DeSoto Firesweep I 2-Door Sportsman will generally fit in a standard single-car garage. Most modern single-car garages measure about 6 meters (20 feet) in length and about 3 meters (10 feet) in width, so the Firesweep’s size fits within these parameters. However, it's a tight fit width-wise, so care should be taken when parking to avoid scratches or damage.

The 1958 DeSoto Firesweep I coupe has a ground clearance of 142 mm (5.6 inches). This moderate clearance is typical for American passenger cars from the 1950s and is sufficient for normal urban and suburban roads. However, it might be less suitable for rough terrain or poorly maintained roads where higher clearance is preferable. The ride height contributes to a lower center of gravity, which helps with vehicle stability and smooth ride on paved surfaces.

At 1989 mm (78.3 inches) wide, the 1958 DeSoto Firesweep I 2-Door Sportsman is relatively wide for a coupe of its era. This width reflects the American design trend of spacious and comfortable interiors with broad road presence. Compared to contemporaries such as the 1958 Chevrolet Bel Air coupe, which is narrower (approximately 1970 mm or 77.6 inches), the Firesweep's width enhances passenger comfort and road stability but may require more care in tight parking situations.

With a length of 5499 mm (216.4 inches), the Firesweep coupe has a commanding road presence, typical of late 1950s American cars designed to maximize passenger space and styling flair. This length allows for spacious interiors and generous trunk capacity, making it practical for longer trips or family use despite being a 2-door model. The extended front and rear overhangs enhance traditional styling, contributing to the vehicle’s classic look.

The Firesweep’s height is 1443 mm (56.8 inches), which is relatively low and enhances its sleek coupe styling. The lower stature provides adequate headroom for most occupants due to clever interior packaging typical of 1950s luxury vehicles. The height helps to improve aerodynamics slightly compared to taller sedans, reducing wind resistance and contributing to better high-speed stability, although aerodynamics were generally less optimized than modern vehicles.

Compared to the previous 1957 DeSoto Firesweep generation, the 1958 facelifted Firesweep I 2-Door Sportsman maintained very similar exterior dimensions and curb weight. Any dimensional changes were subtle, mainly involving styling tweaks rather than size alterations. The 1958 model kept the impressive 5499 mm length, around 1989 mm width, and approximate curb weight near 1749 kg, preserving the large and sturdy build prestige that the Firesweep was known for in its class.

The 1958 DeSoto Firesweep I 2-Door Sportsman compares closely with other full-size American coupes of the late 1950s such as the Chrysler Windsor or Buick Special. Its length of 5499 mm (216.4 inches) and weight of approximately 1749 kg (3855 lbs) put it in the upper range of full-size coupes, offering a spacious cabin and solid build. While some competitors were slightly lighter or smaller, the Firesweep emphasizes luxury, comfort, and road presence, making it a notable choice for buyers seeking classic 1950s American style.

While specific interior dimensions for the 1958 Firesweep aren't provided, the large exterior dimensions generally translate into comfortable front and rear seating room typical of late 1950s American coupes. The Firesweep I Sportsman likely offered plush bench seats, ample legroom, and headroom for four passengers. Features of the era might include luxury trim, two-tone upholstery, and large windows for visibility. The sizable trunk space complemented passenger comfort for longer journeys, enhancing its appeal as a luxurious and practical coupe.
