1972 Opel Commodore B Dimensions, Size & Specs

The Opel Commodore B has a curb weight ranging from 1200 kg to 1265 kg (2645 to 2788 lbs) and a maximum weight between 1640 kg and 1720 kg (3616 to 3794 lbs). The variation in these weights depends on factors such as specific model trims, optional equipment, and fuel load. A moderate curb weight allows for responsive handling and fuel efficiency, while maintaining structural rigidity. The maximum weight includes passengers and cargo, affecting acceleration, braking, and fuel consumption. Overall, the weight balance of the Commodore B contributes to a stable ride with good performance characteristics, typical of sedans from the early 1970s.

The luggage capacity of the Opel Commodore B is 408 liters (approximately 14.4 cubic feet), which offers a decent amount of storage space for a mid-size sedan from the 1970s. This capacity is sufficient for typical family needs such as grocery shopping, luggage for weekend trips, or sports equipment. While not as expansive as modern hatchbacks or SUVs, the Commodore B’s trunk space is well-designed to maximize utility without compromising passenger comfort. Its practical cargo volume makes it a sensible choice for families requiring balanced passenger space and luggage accommodation.

The Opel Commodore B offers a ride height or ground clearance ranging from 112 mm to 140 mm (4.4 to 5.5 inches). This moderate ground clearance is typical for sedans of its time, providing a good balance between a low center of gravity for improved handling and sufficient clearance to navigate uneven road surfaces and minor obstacles. While not designed for off-road driving, this clearance level ensures comfortable urban and highway driving. Drivers should be cautious on rough terrain or speed bumps to avoid undercarriage damage, but overall it is well-suited for normal road conditions.

With a length of 4607 mm (181.3 inches), a width of 1728 mm (68 inches), and a height just under 1415 mm (55.7 inches), the Opel Commodore B comfortably fits into a standard residential garage. Standard garages typically measure about 2400 mm (7 feet 10 inches) in width and 4800 mm (15 feet 9 inches) in length, which provides enough clearance around the vehicle for opening doors and maneuvering. Therefore, owners should have no issues parking the Commodore B indoors, offering protection from weather and security for the vehicle.

Compared to the earlier Commodore A generation, the Commodore B experienced slight dimensional changes that improved its overall presence and practicality. The Commodore B is longer at 4607 mm compared to the Commodore A's approximate length of around 4560 mm (179.5 inches), making it slightly more spacious inside. In terms of width, the Commodore B maintains a similar stance at about 1728 mm, offering consistent passenger room. Height-wise, the Commodore B's range of 1405-1415 mm is comparable to its predecessor, although subtle design tweaks enhanced aerodynamics and styling. The updated weight also reflects changes in materials and equipment, with a curb weight increase that contributes to stability and comfort. Overall, the Commodore B built on the solid foundation of the A generation, providing refinements rather than radical changes.

The Opel Commodore B's dimensions—4607 mm in length and 1728 mm in width—align well with contemporaries such as the Ford Capri, BMW 2002, and Fiat 132. While slightly longer than some competitors, the Commodore B provides a slightly more spacious cabin and trunk capacity. Its ground clearance and height support sporty handling but remain practical for everyday use. In terms of weight, it is lighter than many American mid-size cars of the same era, which contributes to nimble driving dynamics. Overall, the Commodore B strikes a balance between size, weight, and comfort, offering competitive space without the bulkiness associated with some rivals, making it a practical choice among mid-size sedans of the 1970s.

The Opel Commodore B, produced from 1972 to 1978, is a classic mid-size sedan designed to offer a blend of sporty driving dynamics and family practicality. It features a streamlined yet muscular body style typical of the 1970s, with clean lines and a relatively low profile for its size. Underneath, it is equipped with efficient inline-six engines that provide a good balance of performance and fuel economy for the period. The interior was designed to comfortably seat five passengers with adequate legroom and headroom, combined with functional controls and a straightforward dashboard layout. The car was aimed at customers needing reliable transport for daily commuting and leisure driving, providing comfort without excessive size.

The Opel Commodore B's curb weight varies between 1200 kg and 1265 kg (2645 to 2788 lbs), which is relatively light for a mid-size sedan of the 1970s. This moderate weight contributes positively to fuel efficiency and handling characteristics. Reduced weight means the engine requires less effort to accelerate the vehicle, resulting in better mileage compared to heavier counterparts. While fuel economy standards were not as stringent during its production years, the Commodore B offered decent fuel consumption figures relative to its performance segment. Additionally, the balanced weight supports responsive steering and stability, enhancing driving pleasure without sacrificing efficiency.

The Opel Commodore B is well-suited for everyday urban use thanks to its moderate size, practical ground clearance, and ample luggage capacity. Measuring 4607 mm (181.3 inches) in length and 1728 mm (68 inches) in width, it provides enough interior space for comfort while remaining maneuverable in city traffic and parking environments. Its ground clearance of 112–140 mm (4.4–5.5 inches) offers enough clearance to clear speed bumps and uneven pavements without issue, although caution is advised on very rough surfaces. The decent 408-liter (14.4 cubic feet) trunk allows for convenient grocery runs, luggage for trips, or transporting sports equipment.
