1956 Mercedes-Benz W180 II Cabriolet Dimensions, Size & Specs

The curb weight of the Mercedes-Benz Ponton W180 II Cabriolet ranges from approximately 1385 kg to 1400 kg (3054 to 3086 pounds). The maximum gross vehicle weight capacity is about 1790 kg (3946 pounds). This weight provides the vehicle with a sturdy build typical of mid-1950s luxury convertibles, contributing to its smooth ride and stability, while also accommodating the weight of passengers and cargo safely.

With an overall height of 1530 mm (60.2 inches), the Mercedes-Benz Ponton W180 II Cabriolet stands moderately low compared to modern SUVs but typical for mid-century luxury convertibles. This lower height enhances its aerodynamic profile and center of gravity, improving handling dynamics and stability on the road. It also makes entering and exiting the vehicle relatively easy, though parking clearance should be monitored in spaces with low overhead clearance.

Most standard residential garages have a width of roughly 2.4 to 2.7 meters (8 to 9 feet) and lengths ranging from 5 to 6 meters (16.4 to 19.7 feet). Given the Ponton W180 II Cabriolet's dimensions—1790 mm (70.5 inches or 5.9 feet) wide and 4700 mm (185 inches or 15.4 feet) long—it comfortably fits within a standard garage in terms of length and width. The vehicle’s height of 1530 mm (60.2 inches or roughly 5 feet) also easily fits typical garage height clearances. Therefore, storage in most home garages is feasible without issues.

The Ponton W180 II Cabriolet is 1790 mm (70.5 inches) wide, which is somewhat narrower than many modern convertibles, which often range from 1800 mm to over 1900 mm in width. This slightly narrower width reflects the design priorities of the 1950s, focusing on elegant, streamlined proportions without the bulkiness seen in some contemporary models. The narrower profile can be advantageous for navigating tight city streets and parking spaces.

While detailed interior dimensions are not commonly available for the W180 II Cabriolet, its length of 4700 mm (185 inches) and width of 1790 mm (70.5 inches) indicate it offers fairly generous passenger space for a two-door convertible of its era. The design focuses on driver and passenger comfort with ample legroom and shoulder room, typical of Mercedes-Benz’s luxury standards from the 1950s. The convertible top also provides an airy feeling when down, enhancing the sense of space.

Compared to the predecessor W180 I Cabriolet, produced earlier in the 1950s, the W180 II Cabriolet maintains very similar exterior dimensions, with minor refinements. Both generations share a comparable length of around 4700 mm (185 inches), width close to 1790 mm (70.5 inches), and height near 1530 mm (60 inches). However, the W180 II benefits from subtle styling updates and mechanical improvements, while retaining the classic Ponton proportions. This continuity gives owners a sense of evolution rather than a radical size change.

When compared to other luxury cabriolets of the 1950s, such as the BMW 503 or Jaguar XK120, the Mercedes-Benz Ponton W180 II Cabriolet is competitively sized. Its length of 4700 mm (185 inches) is comparable or slightly longer than many contemporaries, and its width of 1790 mm (70.5 inches) fits within the typical luxury convertible range of that era. The weight, between 1385 and 1400 kg (3054 to 3086 lbs), also matches the mid-20th century emphasis on solid build quality and materials. Overall, the Ponton offered a well-balanced size that delivered comfort, style, and performance.

The maximum gross weight (maximum weight capacity) of the Ponton W180 II Cabriolet is approximately 1790 kg (3946 pounds). This number represents the sum of the curb weight plus passengers, cargo, and any optional equipment. With a curb weight ranging from 1385 to 1400 kg (3054 to 3086 pounds), this leaves around 390 to 405 kg (860 to 893 pounds) available for occupants and luggage. This capacity is adequate for a luxury two-door convertible, supporting typically two passengers comfortably, plus light baggage or accessories.

Produced from 1956 to 1959, the Ponton W180 II Cabriolet reflects design and engineering values of the post-war era, emphasizing elegant styling combined with robust build quality. The 'Ponton' name refers to the pontoon-shaped bodywork, which was aerodynamic and modern at the time, resulting in sleek yet spacious dimensions: 4700 mm length, 1790 mm width, and 1530 mm height. During this era, convertibles were crafted to blend luxury, open-air enjoyment, and road presence without excessive size, making the Ponton a symbol of sophistication in a manageable package. Its weight and dimensions supported smooth handling for a grand touring experience typical of mid-20th century Mercedes-Benz models.
