2020 Audi S8 (D5) Dimensions, Size & Specs

The curb weight of the Audi S8 (D5) stands at 2230 kg (4916 lbs), with a maximum permissible vehicle weight of 2835 kg (6249 lbs). Despite its relatively heavy build, the S8 is engineered with advanced suspension and powertrain technologies that ensure agile handling and impressive acceleration. The weight helps provide stability and a luxurious ride, while the quattro all-wheel-drive system compensates for mass to optimize cornering and traction.

The Audi S8 (D5) offers a luggage capacity of 505 liters (17.8 cubic feet), which is generous for a high-performance luxury sedan. This capacity allows for adequate storage for long trips or business use without compromising passenger comfort. Compared to other luxury sedans in its class, the S8 provides a competitive trunk space, balancing sportiness and practicality effectively.

A standard home garage typically measures around 2440 mm (8 feet) in width and 4880 mm (16 feet) in length. With the Audi S8 (D5) being 5179 mm (203.7 inches) long and 1945 mm (76.6 inches) wide (excluding mirrors), the S8 fits lengthwise in most standard garages, albeit with a tight clearance of about 300 mm (11.8 inches). Width-wise, the car fits comfortably, but with mirrors opened at 2130 mm (83.9 inches), you may need to fold mirrors to avoid scraping the sides. Overall, it fits in standard garages but requires some care with mirror clearance.

Compared to the predecessor Audi S8 (D4) generation, the D5 generation is slightly larger and more refined in terms of exterior dimensions. The D5 length measures 5179 mm (203.7 inches) versus roughly 5170 mm (203.5 inches) in the D4. Width and height have also slightly increased to enhance interior space and road presence. The D5 is more aerodynamic, and despite increased size, features lighter weight materials to partially offset mass gain. The increase in size results in improved passenger comfort, particularly in rear-legroom and shoulder space.

The Audi S8 (D5) comes equipped with 20-inch rims sized 9J x 20, paired with 265/40 R20 104Y XL tires. These large wheels and wide tires provide enhanced grip and stability, contributing to sharp handling and confident cornering at speed. The XL (extra load) tires support the heavy weight of the vehicle, ensuring durability and safety. Larger rims with low-profile tires generally improve steering response and road feedback but may slightly soften ride comfort on rough surfaces.

The Audi S8 (D5) has a roof load capacity of 90 kg (198 lbs). This allows for the safe fitting of roof racks, cargo boxes, or bike carriers without compromising structural integrity. However, care should be taken not to exceed this limit to avoid damage or unstable conditions. The capacity is typical for a sedan of this class and suits lifestyle accessories such as ski racks or additional luggage carriers for vacations.

In the high-performance luxury sedan segment, the Audi S8 (D5)’s dimensions and weight position it competitively. Its length of 5179 mm (203.7 inches) and width of 1945 mm (76.6 inches) are similar to rivals like the BMW M760Li and Mercedes-AMG S63. The weight of 2230 kg (4916 lbs) is on par or slightly heavier due to advanced technology and quattro all-wheel drive. The S8 emphasizes a balance between size for comfort and agility, offering a spacious cabin with dynamic driving capabilities relative to similar models.

The 2020 Audi S8 (D5) ushers in a new era with a design language emphasizing both imposing presence and aerodynamic efficiency. Compared to earlier models, the D5 features a more angular yet elegant exterior, incorporating Matrix LED headlights and a wide Singleframe grille. Under the hood, it introduces a powerful 4.0-liter twin-turbo V8 with mild-hybrid technology, improving performance and efficiency. Advanced driver-assistance systems and a digitalized cockpit with the latest MMI touch response system set it apart from former generations, enhancing both comfort and driving dynamics.

While overall exterior dimensions are a good indicator, the Audi S8 (D5) focuses heavily on interior spaciousness and comfort. Thanks to its 5179 mm (203.7 inches) length and optimized packaging, the sedan offers ample legroom and headroom for both front and rear passengers. High-quality materials, multi-zone climate control, and advanced sound insulation contribute to a luxurious cabin atmosphere. Rear passengers especially benefit from generous shoulder width and adjustable seats, making it a premier choice for chauffeured transportation or executive travel.
