The W126 S-class has a consistent width of 1820 mm (71.7 inches), providing a stable stance and substantial interior space for passengers. Its height ranges between 1430 mm and 1436 mm (56.3 to 56.5 inches), which contributes to a sleek yet formal silhouette befitting a luxury sedan. These dimensions help the W126 to command an impressive road presence while maintaining aerodynamic efficiency for its era.

The curb weight of the Mercedes-Benz S-class SE (W126) spans from 1560 kg to 1695 kg (approximately 3,439 to 3,736 pounds), depending on the model variant and the equipment fitted. A relatively heavy car for its size, this weight contributes to a smooth, planted ride and enhances the vehicle's stability and sound insulation. Heavier weight also adds to the feeling of solidity and safety, which are key attributes of the S-class.

The maximum weight for the Mercedes-Benz S-class SE (W126) ranges from 2080 kg to 2170 kg (about 4,586 to 4,784 pounds). This figure includes passengers, cargo, and the vehicle's own curb weight. The maximum weight indicates the vehicle’s ability to safely carry additional load without compromising performance or safety. It ensures that the S-class can comfortably accommodate passengers and luggage while maintaining its expected driving dynamics.

The luggage capacity of the W126 S-class is between 500 liters and 505 liters (approximately 17.7 to 17.8 cubic feet). This is a generous size for a luxury sedan of its time, providing ample space for travelers' bags, groceries, or other cargo needs. The well-designed trunk space combined with a traditional sedan layout offers practicality alongside luxury features.

The Mercedes-Benz S-class SE (W126) comes with rim sizes ranging from 6J x 14 to 6.5J x 14, paired with tire sizes including 195/70 R14, 195/75 R14, and 205/70 R14.

The W126 S-class, with its length ranging up to 5145 mm (202.6 inches) and width of 1820 mm (71.7 inches), fits within the dimensions of a standard single-car garage, though it may be a tight fit in narrower or older garages. Standard garages typically measure around 2400 mm (8 feet) wide and 5400 mm (18 feet) long, so the W126 fits comfortably lengthwise. However, extra care might be needed when parking to ensure ease of access and avoid door dings, especially in garages without ample width.

The W126 offered a length between 4995 mm and 5145 mm (196.7 to 202.6 inches), which is generally longer than the W116, which measured approximately 5060 mm (199.2 inches) at its longest in long-wheelbase versions but was often shorter in some standard variants. Width remained similar, with the W116 about 1800 mm (70.9 inches) wide compared to the W126's 1820 mm (71.7 inches). The W126's slightly larger dimensions translated into a more spacious and comfortable cabin and enhanced road presence, reflecting technological and design advancements over its predecessor.

During its era, the W126 stood among the larger full-size luxury sedans, competing with the likes of the BMW 7 Series E23 and Audi 100. In terms of length and width, the W126 was generally larger, with up to 5145 mm (202.6 inches) in length and 1820 mm (71.7 inches) in width, compared to BMW E23’s approximate length of 4970 mm (195.7 inches) and Audi 100’s 4820 mm (189.8 inches). This size advantage allowed the W126 to offer superior interior room and a more commanding road presence. Its luggage capacity, ride comfort, and weight also reflected its positioning at the top of the luxury segment.

This classic sedan body style emphasizes passenger comfort, elegance, and practicality. The sedan layout provides spacious seating for front and rear passengers while maintaining a separate luggage compartment with a capacity of around 500 liters.
