2006 Audi S8 (D3) Dimensions, Size & Specs

The 2006-2007 Audi S8 (D3) has a curb weight of 1940 kg (4277 lbs), which is the weight of the vehicle without passengers or cargo but with all necessary fluids. Its maximum weight, also known as gross vehicle weight rating (GVWR), is 2540 kg (5600 lbs), representing the maximum allowable weight including passengers and cargo. The relatively heavy curb weight supports stability and ride comfort, while the powerful engine compensates to provide excellent performance.

The Audi S8 (D3) offers a luggage capacity of 500 liters (17.7 cubic feet). This volume is generous for a luxury sedan, allowing for ample storage space for suitcases, groceries, or sports equipment. Whether for long journeys or everyday errands, the trunk space is sufficient for most needs, enhancing the vehicle’s practicality without compromising its sporty character.

The Audi S8 (D3) is 1897 mm (74.7 inches) wide, a dimension that contributes to both its aesthetics and driving dynamics. A wider track generally improves stability and cornering grip on the road, benefiting overall control. However, the width also requires careful attention when navigating narrow streets or parking, although it remains sized compatibly with most modern urban environments.

The 2006-2007 Audi S8 (D3) comes fitted with 9J x 20 inch rims and 265/35 R20 tires. These large and wide tires deliver enhanced grip and road contact, improving handling, braking, and cornering performance. The low-profile tire size helps reduce sidewall flex for sharper steering feedback, though it may slightly reduce ride comfort on rough surfaces.

With a height of 1424 mm (56.1 inches), the Audi S8 (D3) maintains a sleek, low-slung stance typical of luxury performance sedans. This height provides a good balance between interior headroom and aerodynamic efficiency. Passengers enjoy comfortable headroom, especially important for rear-seat occupants, while the relatively low height helps reduce drag for better fuel efficiency and higher top speeds.

The Audi S8 (D3) measuring 5062 mm in length, 1897 mm in width, and 1424 mm in height is generally compatible with a standard residential garage, which typically offers around 5500 mm (18 feet) length and 2400–2700 mm (8–9 feet) width and height clearances. The S8’s width of 1897 mm (74.7 inches) means there is reasonable room on either side for maneuvering, but owners should measure their garages as space can be tight depending on door widths and other stored items.

Compared to its predecessor, the Audi S8 (D2), the D3 generation grew slightly in size, offering improved passenger space and luggage capacity. The D3 is longer (5062 mm vs. 5070 mm), wider, and a bit heavier, reflecting enhanced luxury features and structural reinforcements. Performance-wise, the D3 utilizes a more powerful V10 engine compared to the D2’s V8, providing a significant boost in horsepower and torque, with refined handling due to updated suspension and chassis dynamics.

The Audi S8 (D3) closely matches its contemporaries such as the BMW 7 Series (especially the M7 as a performance variant) and the Mercedes-Benz S63 AMG in size, with all vehicles offering lengths in the range of 5 meters and widths around 1.9 meters. While the S8 may be slightly lighter or heavier depending on trim, its dimensions ensure competitive interior comfort and road presence. Performance-wise, the S8's V10 engine and quattro all-wheel drive differentiate it by blending high power with excellent traction compared to the rear-wheel-drive-focused rivals.

The 2006-2007 Audi S8 (D3) has a roof load capacity of 100 kg (220 lbs). This capacity allows owners to mount roof racks or carriers suitable for items like bicycles, skis, or luggage boxes, providing added versatility for travel and outdoor activities. It's important to stay within this limit to avoid affecting vehicle stability and damaging the roof structure. Given the S8’s performance orientation, the roof load should be carefully considered not to compromise driving dynamics.
