2009 Mercedes-Benz S-class Long (V221, facelift 2009) Dimensions, Size & Specs

When the mirrors are opened, the width of the V221 S-class Long expands to 2120 mm (83.5 inches). This measurement is important because it affects the car’s ease of maneuvering in tight spaces, parking, and clearance in narrow roads or garages. The substantial mirror width reflects the car’s luxurious and broad stance, ensuring better rear visibility but requiring additional space compared to the car’s body width of 1871 mm (73.7 inches).

The curb weight of the S-class Long (V221 facelift 2009) ranges between 1880 kg to 2200 kg (4146 to 4850 lbs) depending on the specific model variant and equipment. A heavier curb weight contributes to stable highway cruising and a solid feel inside the cabin but can slightly reduce nimbleness and fuel efficiency. Mercedes balances the weight with advanced suspension and chassis dynamics to maintain smooth, comfortable ride quality and handling expected in a luxury sedan.

The maximum weight, also known as Gross Vehicle Weight Rating (GVWR), for the V221 S-class Long facelift varies between 2535 kg to 2715 kg (5590 to 5987 lbs) depending on configuration. This figure includes the curb weight plus passengers, cargo, and additional equipment. Staying within this limit is essential for safety, performance, and legal compliance, ensuring the vehicle can safely carry its occupants and luggage without overloading the chassis or brakes.

The luggage capacity of the S-class Long V221 facelift ranges between 550 and 560 liters (19.4 to 19.8 cubic feet). This generous trunk space is designed to comfortably hold several large suitcases or multiple smaller bags, making it suitable for long trips and daily errands. Compared to other full-size luxury sedans of the era, the S-class Long offers competitive or slightly superior cargo volume, balancing generous passenger comfort with ample storage space.

Standard residential garages typically range around 2.4 to 2.7 meters (7.9 to 8.9 feet) in width and about 5.0 to 6.0 meters (16.4 to 19.7 feet) in length. With a length of 5226 mm (5.23 m or 17.15 feet) and an opened mirror width of 2120 mm (2.12 m), the S-class Long will generally fit into most standard garages in length but may be tight width-wise, especially with mirrors open. Drivers often need to fold the mirrors or be cautious to avoid scraping, particularly in narrower garages.

Compared to its predecessor, the pre-facelift V221 (produced 2006–2009), the facelifted 2009 S-class Long maintained similar overall dimensions, with a length around 5226 mm, width about 1871 mm, and height near 1479 mm. The facelift brought mainly aesthetic and technological upgrades rather than size changes. The consistency in dimensions ensured continuity in interior space, comfort, and exterior presence while updating styling and equipment to keep the model contemporary.

The S-class Long facelift offers a variety of rim sizes: 8J x 17, 8.5J x 19, 9.5J x 19 inches, along with several tire size options like 235/55 R17, 255/35 R20, 275/35 R20, 275/40 R19, 255/40 R19, 255/45 R18, and 275/45 R18. Larger rims and lower-profile tires generally enhance handling and cornering by reducing sidewall flex but can reduce ride comfort due to stiffer tire sidewalls. Conversely, smaller rims with taller tires usually offer a smoother ride but with slightly less sharp handling. The S-class balances these for luxury and performance.

The V221 facelift S-class Long stands on the larger side among full-size luxury sedans of its era. Comparable models include the BMW 7 Series and Audi A8. For instance, the 2009 BMW 7 Series Long Wheelbase measures about 5239 mm in length, nearly identical, but can be slightly wider or narrower depending on trim. Compared to these rivals, the S-class Long offers competitive length and width, prioritizing rear passenger comfort and cargo capacity, making it a benchmark in its segment for spaciousness and elegantly balanced proportions.

The roof load capacity of the facelifted V221 S-class Long is rated at 100 kg (approximately 220 lbs). This figure sets the maximum allowable weight for roof-mounted accessories such as roof boxes, luggage racks, or roof-top carriers. Exceeding this limit can compromise vehicle stability, suspension, and safety. Given the S-class is a luxury sedan designed primarily for comfort and refinement, roof loading is typically minimal and secondary to preserving ride quality and aerodynamics.
