2018 Audi A7 Sportback (C8) Dimensions, Size & Specs

The width of the Audi A7 Sportback (C8) is 1908 mm (about 75.1 inches) without mirrors. When adding the mirrors opened, the width extends to 2118 mm (approx. 83.4 inches). This width ensures stability on the road and also impacts garage parking considerations, especially with the mirrors extended.

The height of the Audi A7 Sportback (C8) measures between 1419 mm to 1422 mm (approximately 55.9 to 56 inches). This relatively low height accentuates its sporty hatchback silhouette and contributes to a lower center of gravity, enhancing handling and stability. The height also plays a role in aerodynamic efficiency, aiding fuel economy and driving dynamics.

The curb weight of the Audi A7 Sportback (C8) ranges from 1695 kg to 2065 kg (about 3737 to 4555 pounds), depending on engine choice, trim, and additional equipment. Lighter variants provide more agility and improved fuel efficiency, while heavier versions may include more comfort or technology features. The weight balance is optimized to maintain a smooth ride and responsive handling.

The maximum authorized or gross vehicle weight of the Audi A7 Sportback (C8) varies between 2300 kg and 2650 kg (approximately 5071 to 5842 pounds). This weight includes the vehicle itself, passengers, cargo, and any additional load, indicating the car’s capacity for safely carrying occupants and luggage within manufacturer limits.

Luggage capacity of the Audi A7 Sportback (C8) ranges from 380 to 535 liters (about 13.4 to 18.9 cubic feet) with the rear seats upright. Folding the rear seats increases the volume significantly, providing 1235 to 1390 liters (roughly 43.6 to 49 cubic feet) of space. This versatility is particularly useful for transporting larger items or luggage on longer trips, reinforcing the A7’s practicality alongside its sporty design.

In most regions, a standard garage typically measures around 2.4 to 2.7 meters (7.9 to 8.9 feet) in width and over 5 meters (16.4 feet) in depth. Given the Audi A7 Sportback (C8) dimensions—length up to 4.976 meters (16.3 feet) and width including mirrors up to 2.118 meters (6.95 feet)—it fits comfortably in standard garages. However, the opened mirrors width near 2.12 meters (83.4 inches) may require careful maneuvering in narrower garages. Height is generally not an issue. Overall, the A7 is garage-friendly, but mirror folding helps optimize space.

Compared to the previous C7 generation Audi A7, the C8 saw slight dimensional refinement. The C8 is generally similar in length, hovering close to 4.97 meters, but it is marginally wider at 1.908 meters excluding mirrors, enhancing interior space and road presence. The height of the C8 is marginally lower or comparable, contributing to an even sportier profile. Weight has increased slightly due to added technology and safety equipment, but this is offset by improved chassis dynamics. The C8's design emphasizes sharper lines, more aggressive stance, and advanced interior features, all building upon the solid foundation of the C7.

When compared to competitors like the BMW 8 Series Gran Coupe and Mercedes-Benz CLS-Class from the same production era, the Audi A7 Sportback (C8) stands out slightly in length and width. The A7's length near 4.97 meters (approx. 195.7 inches) is roughly comparable or marginally longer than its rivals, while its width with mirrors is also impressive, contributing to a strong road presence. Its hatchback design offers more practical luggage space with flexible rear seat folding compared to the traditional sedan trunks of rivals. The Audi's height remains sportier and lower than many competitors, helping handling and styling distinctiveness.

The Audi A7 Sportback (C8) offers a variety of rim sizes ranging from 18 inches up to a sizable 21 inches, with options including 8J x 18, 8.0J x 18, 8.5J x 19, 8.5J x 20, and 8.5J x 21. Tire sizes correspond to these rims and include 225/55 R18, 225/55 R18 102Y, 245/45 R19, 255/40 R20, and 255/35 R21. Lower profile tires and larger rims improve grip and handling response but might slightly reduce ride comfort due to stiffer sidewalls. Smaller rims with higher profile tires support a more cushioned ride, better for rougher roads. Audis balance these choices to cater to a wide range of driver preferences.
