1955 BMW Isetta Dimensions, Size & Specs

The 1955 BMW Isetta is extremely lightweight, with a curb weight of only 370 kg (816 lbs). Its maximum weight capacity is 600 kg (1323 lbs), meaning it can carry an additional 230 kg (507 lbs) including passengers and cargo. This lightweight design contributes to its nimble handling and fuel efficiency, which were key selling points for the microcar during its production period from 1955 to 1962.

Yes, the BMW Isetta, with its very compact dimensions (2355 mm long, 1380 mm wide, and 1340 mm tall), easily fits inside a standard garage. Standard garages typically measure about 2400-3000 mm in width and 4800-6000 mm in length (approximately 8-10 feet wide and 16-20 feet long). The Isetta's small footprint allows for ample clearance, making it highly convenient for urban dwellers with limited parking space.

Compared to other vehicles from the mid-1950s, the BMW Isetta was significantly smaller. While average sedans and compact cars of that era measured around 4000-4500 mm (157-177 inches) in length, the Isetta’s length was just 2355 mm (92.7 inches). Its microcar classification reflects this size difference, designed primarily for short-distance urban commutes, where smaller size equated to ease of parking and maneuverability.

Given its exterior dimensions, the BMW Isetta offers only the essentials for two occupants. The cabin is tightly compact, with seating positioned side-by-side, although the width is just 1380 mm (54.3 inches). Despite the small interior, the design prioritizes efficient use of space, including a front-opening door that maximizes ease of access. However, interior cargo space is minimal, suited mainly for small personal items.

The BMW Isetta’s height is 1340 mm (52.8 inches), quite low by modern standards but adequate for a microcar. This low profile contributes to its aerodynamic shape and compact nature. While headroom is sufficient for average-sized adults, taller passengers might find it somewhat restrictive. The height also helps the Isetta fit into low-clearance parking areas and garages, further enhancing its urban practicality.

The BMW Isetta was originally designed and produced by Iso in Italy before BMW acquired the license. The BMW version retained the microcar's tiny footprint but made improvements in build quality, reliability, and styling. Dimension-wise, the BMW Isetta remained similar to the original Iso Isetta design, maintaining the same compact size with a length of 2355 mm, width of 1380 mm, and height of 1340 mm, focusing on practicality rather than increasing physical dimensions.

When compared to contemporaries like the Messerschmitt KR200 or the Fiat 500, the BMW Isetta holds its own as one of the most compact and uniquely designed microcars. For instance, the Fiat 500 was longer at about 2970 mm (117 inches), while the Messerschmitt KR200 was similarly compact but narrower. The Isetta’s width of 1380 mm and length of 2355 mm ensure it remains one of the smallest in external size, offering exceptional maneuverability despite accommodating two passengers.

The BMW Isetta was equipped with a modest single-cylinder two-stroke engine, typically around 250 cc, designed for low power but high efficiency. Fuel economy was a standout feature, with consumption often cited at around 3-4 liters per 100 km (approximately 59-78 mpg US). The car’s lightweight construction and small engine made it ideal for economical urban travel during the 1950s and early 1960s.

While modern vehicles have significantly evolved, the BMW Isetta remains an iconic and practical microcar when considering space and maneuverability in dense urban environments. Its small size, excellent fuel efficiency, and ease of parking make it suitable for short city commutes. However, its limited speed, minimal storage space, and safety features reflect the standards of its era, meaning it’s better suited for enthusiasts and collectors rather than daily modern use.
