1985 Mercedes-Benz S-class Coupe (C126, facelift 1985) Dimensions, Size & Specs

The curb weight of the Mercedes-Benz S-class Coupe (C126 facelift) varies between 1540 kg and 1750 kg (approximately 3395 to 3858 lbs). Its maximum permissible weight is in the range of 2120 to 2220 kg (4672 to 4893 lbs). This weight range accounts for different engine options and trim specifications. The curb weight indicates the car's weight without passengers or cargo but including all necessary operating fluids and a full tank of fuel.

A standard single-car garage usually measures about 6 meters (19.7 feet) in length and roughly 3 meters (9.8 feet) in width. The 1985–1991 Mercedes-Benz S-class Coupe (C126 facelift), at 4935 mm (4.935 meters/16.2 feet) long and 1828 mm (1.828 meters/6 feet) wide, comfortably fits within these dimensions with some clearance. However, its width should be considered with opened doors, and height clearance in garages with low ceilings should be checked as the coupe stands about 1402 to 1407 mm (55.2 to 55.4 inches) tall.

This generation of the Mercedes S-class Coupe originally came equipped with 7J x 15 rims, which were paired with tire sizes 205/65 R15 or 215/65 R15. These tire dimensions provide a balance between ride comfort and handling, typical of luxury grand tourers of that time. The tire specs indicate a tire width of 205 or 215 mm, sidewall height at 65% of the width, and a 15-inch rim diameter, offering a sturdy yet refined driving experience.

The height of the 1985 to 1991 Mercedes-Benz S-class Coupe (C126 facelift) ranges between 1402 mm and 1407 mm (55.2 to 55.4 inches), with minor variations likely due to model year changes or optional equipment influencing suspension or tire profiles. Overall, this slight difference is negligible and maintains a low and streamlined stance, which contributes to the car’s elegant coupe silhouette and aerodynamic design.

The facelifted 1985–1991 C126 S-class Coupe is an evolution of the original C126 model introduced in 1981. Dimensionally, the facelift model retained very similar exterior measurements, preserving the length at approximately 4935 mm (194.3 in) and width around 1828 mm (71.9 in). The subtle design updates focused more on styling, technology, and comfort rather than a major size revision. Thus, dimension-wise, there is minimal difference between the pre-facelift and facelift versions of the C126 coupe.

Compared to similar luxury grand tourers from the mid-1980s to early 1990s, the C126 facelift Mercedes-Benz S-class Coupe holds its own with a length of 4935 mm (16.2 feet) and width of 1828 mm (6 feet). For example, the BMW 8 Series (E31) of the same era is slightly shorter and often wider, while the Jaguar XJ-S is close in length but generally narrower. The S-class's size emphasizes a balance of grand touring comfort with a stately road presence, positioning it as a competitive option in the large luxury coupe segment.

The Mercedes-Benz S-class Coupe C126 facelift was designed with a focus on luxurious comfort for four passengers, featuring spacious seating and ergonomic design. While exact interior dimensions vary slightly with trim, the cabin offers ample headroom and legroom aided by the coupe’s fairly large dimensions (about 4.9 meters in length). Rear seat space is comfortable for a coupe, though less roomy than a sedan, making it ideal for driver and front passenger comfort with usable space for rear passengers in a grand touring context.

The 1985 facelift of the Mercedes-Benz S-class Coupe C126 primarily introduced design refinements including updated front and rear styling (different bumpers, lights, and grille) alongside upgraded interior features and mechanical improvements. Dimensional changes were minimal or non-existent, with length, width, and height essentially identical to the pre-facelift C126 coupe. The facelift focused on enhancing aesthetics, safety, and technology rather than altering the car's fundamental size.

While exact ground clearance figures for the 1985–1991 S-class Coupe C126 facelift vary slightly with suspension settings, it maintains a typical luxury coupe ride height designed for smooth cruising and good highway stability. The curb weight, ranging from 1540 kg to 1750 kg (3395 to 3858 lbs), combined with Mercedes-Benz's engineering, results in balanced weight distribution, contributing to stable handling despite its size. The weight influences a planted feel on the road, giving a confident yet comfortable driving experience typical of large grand tourers.
