2008 Audi A5 Coupe (8T3) Dimensions, Size & Specs

The standard width of the Audi A5 Coupe (8T3) is 1854 mm (73 inches) without mirrors. When mirrors are opened, the width increases significantly to between 1981 mm and 2020 mm (77.9 to 79.5 inches), depending on specific mirror designs. Drivers should account for this broader profile when maneuvering in tight spaces or narrow parking spots, as the mirror width can add two to three dozen centimeters, making the car wider than it initially appears. This is essential to avoid collisions or mirror damage.

The curb weight of the Audi A5 Coupe (8T3) ranges from 1395 kg to 1670 kg (3075 to 3683 pounds), depending on configuration and equipment. The maximum permissible weight varies between 1895 kg and 2160 kg (4179 to 4762 pounds). The relatively moderate curb weight offers a blend of performance and efficiency, lending itself to agile handling and responsive driving characteristics. Heavier options, often due to larger wheels or extra features, might slightly impact fuel consumption and handling but also add to overall vehicle stability.

The Audi A5 Coupe (8T3) offers a luggage capacity of 455 liters (approximately 16.1 cubic feet) with the rear seats in their normal upright position. This space is practical for everyday needs such as grocery shopping or weekend trips. When the rear seats are folded down, the luggage capacity expands significantly to 829 liters (around 29.3 cubic feet), allowing for the transport of larger or bulkier items. This flexibility enhances the coupe’s usability despite its sporty two-door design.

Generally, the Audi A5 Coupe (8T3) fits comfortably into a standard single-car garage. Most garages are designed with a minimum width of about 2440 mm to 2740 mm (8 to 9 feet), and since the Audi’s width with mirrors folded is 1854 mm (73 inches), there is ample clearance. Even with mirrors opened, the width of up to 2020 mm (79.5 inches or approximately 6.6 feet) typically fits within average garage widths but can be tight in garages with storage or shelving close to the walls. Its length of roughly 4630 mm (182 inches) also suits common garage lengths, making it a practical option for those with standard garages.

The roof load capacity of the Audi A5 Coupe (8T3) is specified at 75 kg (165 pounds). This relatively modest limit means that while the car can support roof racks for items like skis, snowboards, or small cargo boxes, users should avoid heavy loads to prevent damage or negative effects on handling. Given the coupe’s aerodynamic design, large or top-heavy loads may also impact fuel efficiency and stability at high speeds. It’s advisable to distribute weight evenly and ensure secure mounting to maximize safety.

The Audi A5 Coupe (8T3) offers various compatible rim sizes ranging from 7.5J x 17 inches up to 9J x 19 inches. Tire sizes vary accordingly, from 225/50 R17, 245/40 R18, 255/35 R19, to larger specifications depending on the trim and package. Smaller rims and tires typically provide a smoother ride and better comfort due to more tire sidewall cushioning, while larger rims with lower-profile tires enhance handling and aesthetic appeal but may result in a firmer ride. Choosing the right balance depends on driving preferences and road conditions.

The Audi A5 Coupe (8T3) was the inaugural generation introduced in 2007, so it does not have a direct predecessor Audi A5 generation. However, compared to models it effectively replaced, such as the Audi A4 Avant or the Audi TT in sporty coupe roles, the A5 offered a larger and more luxurious package with a longer length of approximately 4630 mm (182 inches), wider track, and a lower height (1372 mm/54 inches) emphasizing sportiness combined with practical interior space. Its design focused on blending elegance with performance, establishing a new standard within Audi’s lineup at the time.

Compared to similar luxury coupes like the BMW 3 Series Coupe (E92) and Mercedes-Benz C-Class Coupe (C204) from the same 2007-2011 timeframe, the Audi A5 Coupe (8T3) holds its own with a competitive length around 4630 mm (182 inches), and width near 1854 mm (73 inches). It offers a refined interior and distinct styling emphasizing a sleek silhouette and clean lines. Its luggage capacity of 455 liters (16.1 cubic feet) is often larger than rivals, providing better practicality. The A5's quattro all-wheel-drive system (available in many trims) offers superior traction compared to some rear-wheel-drive competitors, making it a well-rounded choice for those valuing both performance and usability.

Owners should note that while the Audi A5 Coupe (8T3) fits well in average garage spaces due to its manageable length (4625-4635 mm / 182-182.5 inches) and width (1854 mm / 73 inches), the opened mirror width can range up to 2020 mm (79.5 inches or 6.6 feet). In narrow garages or parking spots, this width requires careful attention to avoid scrapes or damage to mirrors. It is advisable to fold in the mirrors where possible and be mindful when entering tight garage entrances or parking close to walls. Additionally, owners should consider the curb weight, ensuring garage floor capacity is sufficient especially if modifications are planned.
