2021 Mercedes-Benz S-class (W223) Dimensions, Size & Specs

The height of the Mercedes-Benz S-class (W223) is 1503 mm (59.1 inches), which is typical for a full-size luxury sedan, providing a comfortable headroom and a stately stance on the road. The ride height, or ground clearance, is set at 130 mm (5.1 inches), which is suited to urban and highway driving conditions, ensuring that the vehicle's underbody clearance is sufficient to handle speed bumps and uneven roads while also offering a smooth, low center of gravity driving experience. This clearance contributes to both luxury ride quality and performance.

The curb weight of the Mercedes-Benz S-class (W223) ranges from 1920 kg to 2345 kg (4233 to 5170 lbs), depending on the specific model, equipment, and engine options. A heavier curb weight typically reflects solid build quality, advanced safety features, and luxurious appointments, but also influences fuel efficiency and handling characteristics. Despite this weight, the W223 is engineered with advanced suspension and chassis systems to ensure responsive handling, stability at high speeds, and a refined ride that meets the expectations of luxury sedan buyers.

The maximum permissible weight, also known as the Gross Vehicle Weight Rating (GVWR), for the Mercedes-Benz S-class (W223) ranges between 2720 kg and 3070 kg (5998 to 6769 lbs). This includes the vehicle's curb weight plus passengers, cargo, and any additional equipment. Knowing this figure is essential for understanding load capacity limits and ensuring the vehicle operates within safe mechanical and operational parameters. The range varies by variant and options, reflecting different configurations and performance capabilities.

The luggage compartment of the Mercedes-Benz S-class (W223) offers a capacity that ranges from 350 liters to 550 liters (12.4 to 19.4 cubic feet), depending on the seating configuration and optional features. This makes the W223 highly practical for luxury sedan standards, allowing ample space for suitcases, shopping, and other cargo. Some configurations may allow for rear seat folding or flexible storage solutions to increase usable capacity, catering to varying passenger and luggage needs. This flexibility enhances the W223’s appeal as a daily driver and long-distance cruiser.

The Mercedes-Benz S-class (W223) fits into a standard single-car garage, but attention should be paid to the vehicle's width with mirrors extended and its length. With a length of 5179 mm (203.7 inches) and a width of up to 2109 mm (83 inches) including mirrors, it is essential that garages provide sufficient clearance for doors to open and for comfortable ingress and egress around the vehicle. Standard garage widths vary, but many domestic garages can accommodate this vehicle if mirrors are folded in. Height of 1503 mm (59.1 inches) is generally not a concern, as it fits within typical garage door heights.

Compared to its predecessor, the W222 generation, the W223 is slightly longer and wider, with its length increased to 5179 mm from about 5262 mm in the long-wheelbase W222 version but with a more optimized design footprint in the standard wheelbase. The width with mirrors extended is larger, contributing to a more imposing road stance and increased interior space. The W223 also benefits from reduced height (1503 mm vs. 1496 mm for the W222 long-wheelbase), providing a sleeker and more aerodynamic profile. The newer generation focuses on increased interior comfort, improved technology integration, and enhanced ride quality, with size adjustments reflecting these priorities.

When compared to similar full-size luxury sedans such as the BMW 7 Series and Audi A8, the Mercedes-Benz S-class (W223) presents competitive dimensions. Its length of 5179 mm (203.7 inches) is slightly longer or on par with these rivals, while its width of up to 1954 mm (76.9 inches) is broadly similar, offering ample cabin space and presence. Payload capacity and luggage volumes are also competitive, with the W223's luggage capacity of 350-550 liters often matching or exceeding some competitors depending on flexible seat configurations. This size competitiveness emphasizes Mercedes-Benz's focus on luxury, space, and state-of-the-art features in the full-size segment.

The W223 generation offers an extensive range of rim sizes from 18 inches to 21 inches, including rim sizes such as 8J x 18, 8.5J x 19, 10J x 19, 9J x 20, and 10J x 21. Corresponding tire sizes vary from 255/50 R18 up to 285/30 R21. Larger rims and lower profile tires enhance handling precision and aesthetic appeal but can slightly affect ride comfort. Smaller wheels with higher profile tires typically improve ride softness and provide better cushioning over uneven roads. This range of choices allows customers to prioritize between sportiness and comfort according to their preferences.

The Mercedes-Benz S-class (W223), produced since 2020, introduces numerous technological and design advancements over its predecessor. It features the latest MBUX infotainment system with voice control and augmented reality navigation, advanced driver assistance systems including Level 3 semi-autonomous driving features in some markets, improved aerodynamics, and updated luxury materials creating a more refined interior atmosphere. Structurally, it benefits from weight optimization despite added technology, enhancing both efficiency and dynamic capabilities. The W223’s focus is on integrating cutting-edge safety, comfort, and connectivity innovations, maintaining the S-class's reputation as a technological flagship in the luxury sedan segment.
