1971 Mercedes-Benz W108 SEL Dimensions, Size & Specs

The curb weight of the Mercedes-Benz W108 SEL ranges between 1585 kilograms (3496 pounds) and 1705 kilograms (3758 pounds), depending on specific configurations and equipment. The maximum allowable weight (gross vehicle weight rating) spans from 2085 kilograms (4597 pounds) to 2168 kilograms (4779 pounds), which accounts for the weight of passengers, cargo, and fuel the vehicle can safely carry.

Standard residential garage sizes vary, but typically range around 2400 to 3000 millimeters (94.5 to 118 inches) wide and 4800 to 6000 millimeters (189 to 236 inches) deep. The W108 SEL measures 5000 millimeters (196.9 inches) in length and 1810 millimeters (71.3 inches) in width, meaning it fits lengthwise in most garages but may require careful positioning due to its width, especially with mirrors included. Height clearance of 1440 millimeters (56.7 inches) is generally not an issue. Overall, this model fits into a standard garage but leaves limited additional clearance for storage or easy ingress/egress.

At 1810 millimeters (71.3 inches) wide, the W108 SEL is narrower compared to many modern full-size luxury sedans, which can measure upwards of 1900 millimeters (74.8 inches) to 2000 millimeters (78.7 inches). This narrower width reflects design trends of its era focusing on sleekness and urban maneuverability while still maintaining spacious interior comfort.

The W108 SEL is equipped with rim sizes of 6J x 14, meaning 14-inch diameter wheels with a 6-inch width. These relatively modest-sized wheels contribute to a classic ride quality that emphasizes comfort over sporty handling. The tire and rim dimensions were typical for luxury sedans of the early 1970s, offering durability and a cushioned ride rather than aggressive cornering performance.

With a height of 1440 millimeters (56.7 inches), the W108 SEL balances a low profile appearance with sufficient interior headroom for driver and passengers. This moderate height helps reduce aerodynamic drag compared to taller sedans, contributing to improved highway stability and fuel efficiency, while maintaining the elegance and luxury stance typical of Mercedes-Benz flagships of the era.

Compared to its predecessor, the W111 series, the W108 SEL is larger and generally heavier. While the exact dimensions vary by specific model, the W108 SEL's length of 5000 mm (196.9 inches) often exceeded similar models in the W111 range. The weight increase to between 1585 and 1705 kilograms (3496 to 3758 pounds) reflects added luxury features, larger engines, and enhanced safety equipment, delivering a more substantial road presence and refinement.

In the early 1970s, the W108 SEL was among the larger sedans offered by luxury automakers. Its 5000 mm length (196.9 inches) positioned it competitively against contemporaries like the BMW E3 and Jaguar XJ Series 1, which were slightly shorter but similar in width and height. The W108's dimensions emphasized rear passenger comfort and space, especially in the SEL long-wheelbase version, making it a favored choice for chauffeured driving.

The W108 SEL features an extended wheelbase compared to standard W108 models, providing enhanced rear passenger legroom and overall cabin space. This increased interior length significantly improves comfort for rear-seat occupants, making it ideal for executives or those who frequently travel with chauffeurs. The spacious rear seating area is one of the defining characteristics of the SEL variant.

The W108 SEL utilized a body-on-frame construction typical of the era, contributing to its weight but also to durability and repairability. The design included classic Mercedes-Benz styling cues with clean lines and chrome accents, influencing its width and length to create a stately appearance. Additionally, its height and wheel size were optimized for a balance between road manners, comfort, and parking ease, factors important for a luxury sedan aimed at sophisticated clientele.
