The curb weight of the Mercedes-Benz /8 Coupe (W114, facelift 1973) ranges between 1395 kg to 1455 kg (approximately 3074 to 3209 pounds). This variation depends on specific model configurations and optional equipment fitted at the time of production. The relatively moderate weight for a car of this size contributes to its balanced driving dynamics, making it agile yet stable on the road. Maximum weight (gross vehicle weight) ranges from 1915 kg to 1975 kg (4223 to 4355 pounds), reflecting the total load including passengers and cargo capacity.

The Mercedes-Benz /8 Coupe measures 1790 mm (70.5 inches) in width, which typically fits comfortably within a standard single-car garage. Standard garages generally offer widths around 2400 mm (about 94.5 inches) or more, providing enough clearance on either side of the vehicle for door opening and maneuvering. Its length of 4680 mm (184.3 inches) also fits well, as most garages exceed 5500 mm (around 216 inches) in length. Therefore, owners should have no issues parking this classic coupe in a typical residential garage.

The 1973 Mercedes-Benz /8 Coupe, facelift of the W114 generation, maintained similar core dimensions compared to its immediate predecessor, the first /8 series (1968-1972). Length and width saw minimal changes with the facelift focusing more on styling updates and mechanical improvements rather than size alterations. However, subtle refinements in weight management and exterior trim resulted in a slightly lighter curb weight in some variants. This facelift model improved aesthetics with redesigned bumpers and grille while keeping the proven dimensional footprint prized by enthusiasts and collectors.

When compared to other 1970s mid-size coupes such as the BMW E9 or the Audi 100 Coupé S, the Mercedes-Benz /8 Coupe (W114 facelift 1973) holds up with competitive dimensions that favor a spacious yet sporty profile. Measuring 4680 mm long and 1790 mm wide, it’s slightly longer than the E9 BMW 3.0 CS (about 4630 mm) but similar in width, offering more cabin and legroom. Its height at 1395 mm is typical for coupes of the era, emphasizing sleek aerodynamics. The /8 Coupe's combination of refined luxury and classic proportions makes it a well-balanced choice among its peers.

The Mercedes-Benz /8 Coupe facelift models from 1973 supported rim sizes of 6J x 14 and 5.5J x 14. The 14-inch rims offered a balance between vintage styling and ride comfort, as the taller sidewalls typical of tires for these rims absorb road imperfections well. These rim sizes contributed to a smooth driving experience, especially on older and less refined road surfaces, increasing the vehicle’s overall comfort and classic handling characteristics favored by drivers during that time period.

The height of the Mercedes-Benz /8 Coupe (W114 facelift 1973) is 1395 mm (approximately 54.9 inches). This relatively low height is characteristic of coupes, lending improved aerodynamics which help reduce drag and contribute to fuel efficiency. The low roofline enhances the sporty appearance but may slightly limit headroom and upward visibility inside the cabin compared to taller sedans. However, the design balances driver visibility with style, offering a commanding view of the road while maintaining an elegant silhouette.

Curb weight refers to the weight of the vehicle in a ready-to-drive condition including standard equipment, necessary operating consumables such as motor oil and coolant, and a full tank of fuel, but without passengers or cargo. For the Mercedes-Benz /8 Coupe facelift 1973, this ranges from 1395 to 1455 kg (3074 to 3209 lbs). Maximum weight, or gross vehicle weight rating (GVWR), includes the vehicle's curb weight plus the weight of passengers, cargo, and additional equipment. For this coupe, it spans from 1915 to 1975 kg (4223 to 4355 lbs). Adhering to these limits ensures safe handling and performance.

With a length of 4680 mm (184.3 inches), a width of 1790 mm (70.5 inches), and a moderate curb weight ranging from 1395 to 1455 kg (3074 to 3209 lbs), the Mercedes-Benz /8 Coupe from 1973 strikes a good balance between presence and maneuverability in urban settings. While not as compact as smaller sedans or hatchbacks, its design allows it to navigate city streets reasonably well, especially due to its moderate width which fits into most parking spaces and lanes comfortably. Its weight aids in providing a stable ride over uneven pavement, although drivers should be mindful of its longer length when parking or making tight turns.

The 1973 facelift of the Mercedes-Benz /8 Coupe (W114) introduced a number of aesthetic and mechanical upgrades while retaining its iconic design. Cosmetically, this included larger and more pronounced bumpers, a redesigned grille with a more prominent Mercedes-Benz star, and updated lighting elements for improved visibility. Functionally, suspension tuning was refined for better ride comfort and handling. The facelift also saw improved engine options and minor cabin refinements such as upgraded interior materials and instrumentation for enhanced driver comfort. These updates helped the /8 Coupe maintain its blend of luxury, performance, and classic style.
