2011 Audi A8 (D4, 4H) Dimensions, Size & Specs

The Audi A8 (D4, 4H) has a curb weight ranging from 1835 kg to 1995 kg (4048 to 4398 pounds), depending on the specific configuration and optional equipment installed. This weight reflects the car's solid construction, extensive luxury features, and safety equipment. The maximum permissible weight, which includes passengers, cargo, and the vehicle's own weight, is between 2520 kg and 2660 kg (5556 to 5862 pounds). This ensures that the A8 can accommodate up to five passengers comfortably along with their luggage and any additional load, without compromising safety or driving dynamics.

The Audi A8 (D4, 4H) offers a practical yet spacious luggage compartment, with a standard luggage capacity varying between 335 liters and 510 liters (11.8 to 18 cubic feet), depending on the specific model and configuration. This space is sufficient for daily luggage, shopping, or short trips. When more cargo space is needed, folding down the rear seats significantly increases the storage volume to between 906 liters and 1142 liters (32 to 40.3 cubic feet). This feature allows the Audi A8 to handle larger items and luggage for extended travel or transporting bulkier goods, making it versatile for luxury and utility.

The Audi A8 (D4, 4H) has a ride height or ground clearance of 120 mm (4.7 inches). This relatively low ground clearance is typical for luxury sedans intended for on-road use, contributing to its sporty handling, stability, and aerodynamic efficiency. While this low clearance enhances driving dynamics and ride comfort, it also means that drivers need to be cautious when navigating uneven surfaces, speed bumps, or steep inclines to avoid scrapes or damage to the underside. The low height optimizes the car's center of gravity, improving cornering performance and overall ride quality.

The Audi A8 (D4, 4H) supports a variety of rim sizes to suit different preferences for performance and styling. Rim sizes range from 17 inches to 20 inches, specifically: 8.0J x 17, 8J x 18, 8.9J x 18, 8.9J x 19, and 9J x 20. The tire sizes that fit these rims include 235/60 R17, 235/55 R18, 255/45 R19, and 265/40 R20. These options allow owners to balance between ride comfort, handling, road noise, and aesthetics. Larger rims typically enhance the car’s sporty look and handling precision, while smaller rims tend to improve ride comfort and tire longevity.

The Audi A8 (D4, 4H) measures 5137 mm in length (approximately 202.2 inches) and 2111 mm (about 83.1 inches) in width with mirrors opened. Standard residential garage sizes typically range around 2400 mm to 2700 mm (94.5 to 106 inches) in width and about 4800 mm to 6000 mm (189 to 236 inches) in length. Therefore, the A8's length might be on the longer side but it generally fits within standard or slightly larger residential garages. The width with mirrors folded will easily fit, but with mirrors opened, the width extends beyond some narrow garages. Drivers may need to fold in the side mirrors to ensure comfortable clearance. Height at 1460 mm (57.5 inches) is not an issue for most garages.

Compared to its predecessor, the Audi A8 D3 generation (produced from 2002 to 2009), the D4 (4H) generation introduced in 2010 is notably larger and more spacious. The D4 measures 5137 mm (202.2 inches) in length, which is about 177 mm (7 inches) longer than the D3, allowing greater interior comfort and added legroom especially for rear passengers. The width increased to 1949 mm (76.7 inches) from previous narrower dimensions, improving cabin space and road presence. The ride height slightly lower, contributing to a sportier stance. Overall, the D4 enhances luxury and space, reflecting Audi’s focus on combining comfort with a strong road presence. Weight also increased to accommodate more advanced technology and safety features.

In the full-size luxury sedan segment, the Audi A8 (D4, 4H) is competitively sized against rivals such as the BMW 7 Series, Mercedes-Benz S-Class, and Lexus LS. With a length of 5137 mm (202.2 inches), it is comparable to the BMW 7 Series and Mercedes S-Class, which generally range from 5100 mm to 5200 mm in length. The width of 1949 mm (76.7 inches) is also on par with these competitors, ensuring a spacious cabin environment. Notably, the Audi’s sleek and understated design allows it to maintain a somewhat lower height (1460 mm / 57.5 inches), delivering a sportier profile than some taller luxury sedans. Luggage capacity and weight are similarly competitive, making the A8 a balanced choice for buyers seeking refinement, space, and dynamic driving.

The Audi A8 (D4, 4H) has a roof load capacity of 100 kg (220 pounds), which dictates the maximum weight that can be safely placed on the roof. This capacity is adequate for common roof-mounted accessories such as roof boxes, bicycle racks, or light cargo holders, provided the weight doesn't exceed this limit. When considering installing roof racks or other equipment, it is important to factor in the total weight of the equipment plus any load. Exceeding this limit may affect the car’s handling, stability, and roof structure integrity. Always use Audi-approved roof accessories and follow manufacturer recommendations to ensure safety and maintain vehicle warranty.

The Audi A8 (D4, 4H) supports a range of tire and rim sizes, from 17 inches to 20 inches, which allows tuning for varying ride comfort and performance preferences. Factory rim sizes include 8.0J x 17, 8J x 18, 8.9J x 18, 8.9J x 19, and 9J x 20. Tire sizes that optimize safety and handling according to the original specifications are 235/60 R17, 235/55 R18, 255/45 R19, and 265/40 R20. Larger diameter rims with lower profile tires (like the 20-inch option) generally improve cornering and responsiveness but can result in a firmer ride and increased road noise. Conversely, smaller rims with higher profile tires provide a smoother ride, better absorption of bumps, and potentially longer tire life. Choosing the right combination depends on driving style, road conditions, and personal preference.
