1958 DeSoto Firesweep I 4-Door Sedan (facelift 1958) Dimensions, Size & Specs

The curb weight of the 1958 DeSoto Firesweep I 4-Door Sedan is approximately 1760 kg (3881 lbs). This substantial mass was common for American sedans in the late 1950s and contributes to a solid ride quality and road feel. However, the heavier weight might reduce acceleration and fuel efficiency compared to lighter vehicles. The Firesweep's weight also influences braking distances and handling characteristics, necessitating robust suspension components to maintain comfort.

The ride height or ground clearance of this Firesweep sedan is 142 mm (5.6 inches). This clearance is moderate for a sedan from this era, enough to handle urban roads and some uneven surfaces comfortably. However, it might be insufficient for off-road conditions or extremely rough terrain, as low-clearance vehicles risk scraping the undercarriage on obstacles. Overall, the clearance suits everyday driving and typical 1950s road conditions well.

At 1989 mm (78.3 inches) wide, the 1958 DeSoto Firesweep is wider than many contemporary mid-size sedans, which typically measure around 1800 to 1850 mm (70.9 to 72.8 inches) in width. This extra width enhances interior space and road presence but can make parking and maneuvering in tight urban spaces more challenging. The Firesweep's wide stance contributes to its stable ride and distinctive 1950s styling.

With a height of 1443 mm (56.8 inches), the Firesweep sedan is relatively low compared to some other vehicles of its era, which could exceed 1500 mm in height. This lower profile benefits aerodynamic efficiency slightly, though aerodynamics were not a primary focus in 1950s car design. The lower roofline might limit headroom somewhat but increases a stylish, sleek look and can improve forward visibility for the driver by reducing blind spots.

A standard modern garage typically offers dimensions approximately 3 m (10 ft) wide by 6 m (20 ft) deep and about 2.13 to 2.44 m (7 to 8 ft) in height. The 1958 DeSoto Firesweep I sedan, measuring 5499 mm (5.5 m or 18 ft) in length, 1989 mm (just under 2 m or 6.5 ft) in width, and 1443 mm (1.44 m or 4.7 ft) high, will fit comfortably within these standard dimensions. The width and length leave sufficient room for opening doors and walking around, while the height poses no challenge for garage clearance.

Compared to the previous generation DeSoto Firesweep (1956 model), the 1958 facelifted version retained very similar overall dimensions, with only minor styling and trim changes rather than a full redesign. The length and width remained close to around 5490 mm and 1980 mm respectively, maintaining the spacious full-size sedan footprint. This continuity reflects DeSoto's strategy of refining appearance and interior features without drastically altering size or chassis architecture during that transitional period.

When compared to contemporaries like the 1958 Chevrolet Bel Air or the 1958 Ford Fairlane, the DeSoto Firesweep was competitive in size. Its length of 5499 mm (216.4 in) was similar to the Bel Air's approx 5524 mm (217.5 in) and slightly longer than the Fairlane's roughly 5461 mm (215 in). Its width at 1989 mm (78.3 in) was also on par or somewhat wider than these competitors, offering ample interior space and road presence consistent with full-size American sedans of that era.

The 1958 DeSoto Firesweep I sedan, with its large exterior dimensions, provides a spacious cabin typical of American sedans of the 1950s. Seating for up to six passengers was common, with wide bench seats front and rear. The wide body allows generous shoulder and leg room, contributing to passenger comfort on longer trips. The relatively low floor and wide door openings also facilitate entry and exit. Interior appointments in the facelifted 1958 model tend to reflect the stylish trims and comfort features expected in a mid-tier full-size car of the period.

Today, the 1958 DeSoto Firesweep I 4-Door Sedan appeals mainly to classic car collectors and enthusiasts of 1950s American automotive design. Its large size and distinctive styling, highlighted by the facelift details of 1958, represent the glamour and boldness of post-war American cars. It's often used in vintage car shows, parades, and for nostalgic drives. While it may not be as practical as modern cars for daily use, its iconic design and solid construction ensure it remains a treasured classic in the automotive community.
