2005 Aston Martin DB9 Coupe Dimensions, Size & Specs

The Aston Martin DB9 Coupe measures between 1875 mm to 1979 mm in width (73.8 to 77.9 inches). This makes the DB9 relatively wide for a coupe, contributing to its stable handling characteristics and road presence. Compared to similar grand tourers like the Jaguar XK or Mercedes-Benz SL-Class, it tends toward the wider side, especially at the wheel arches due to its performance-oriented stance and wider tires. The DB9’s width helps deliver precise cornering stability while maintaining a luxurious cabin space.

The DB9 Coupe’s height is recorded at 1318 mm (51.9 inches), which is quite low and typical for luxury sports coupes. This low profile helps lower its center of gravity, contributing to improved handling and stability at high speeds. The height also enhances the car’s sleek and aerodynamic design, minimizing air resistance. While the lower roofline might reduce headroom slightly compared to larger cars, it ensures a sportier silhouette that appeals to enthusiasts seeking both style and performance.

The curb weight of the Aston Martin DB9 Coupe varies notably from 1100 kg to 1760 kg (2425 to 3880 lbs), depending on the specific model year and equipment. The lower end of this range may represent lighter prototype versions or early models with fewer optional features, while the higher weights correspond to fully equipped variants with additional luxury or performance packages. This variance is typical for luxury coupes, where customization and optional equipment can significantly affect overall weight. The use of aluminum and other lightweight materials helps keep the weight manageable for a grand tourer.

With the rear seats folded down, the Aston Martin DB9 Coupe provides a luggage capacity of approximately 175 liters. This capacity is modest compared to larger vehicles but sufficient for weekend trips or light luggage needs typical of grand touring. The folding rear seats add flexibility for occasional extra cargo, although the car’s primary focus remains on performance and luxury rather than maximum storage. For travelers planning extensive trips, it's recommended to pack minimally or consider additional storage solutions, but the space neatly balances utility with the DB9’s sleek design.

The DB9 Coupe is equipped with rims sized 9.5J x 19 inches at the rear and 8.5J x 19 inches at the front, paired with tires sized 275/35 ZR19 at the rear and 235/40 ZR19 at the front. These wide low-profile tires optimize road grip and handling, improving traction during spirited driving or cornering. The staggered setup (wider rear tires) enhances rear stability and power delivery, especially given the rear-wheel drive layout. These tire and rim sizes balance ride comfort with high-performance driving dynamics expected from a luxury grand tourer.

The Aston Martin DB9 Coupe, with its length ranging from 4687 to 4767 mm (184.5 to 187.6 inches) and width up to 1979 mm (77.9 inches), generally fits into a standard single-car garage, which typically measures around 2.4 to 2.7 meters (7.9 to 8.9 feet) in width and 4.8 to 6 meters (15.7 to 19.7 feet) in length. However, the upper width near 2 meters means tight clearances may occur in narrower spaces, especially considering door opening space. Owners should measure their garage carefully, factoring in clearance for comfortable entry and exit, especially if storage or additional equipment occupies the garage space.

Compared to the Aston Martin DB7, which the DB9 effectively replaced, the DB9 Coupe is larger in most dimensions. The DB7's length is approximately 4516 mm (177.7 inches), shorter than the DB9's 4687-4767 mm (184.5-187.6 inches). The DB9 is also wider, ranging up to 1979 mm (77.9 inches) versus the DB7’s approximate 1810 mm (71.3 inches). This increase in size improves cabin space, road presence, and stability. Additionally, the DB9’s weight is higher, reflecting more robust build quality and luxury features. Overall, the DB9’s larger footprint contributes to a more refined ride and grand touring comfort compared to the DB7.

When stacked against similar luxury grand tourers like the Jaguar XK, Mercedes-Benz SL-Class, and Porsche 911, the Aston Martin DB9 Coupe is generally longer and wider. For example, the Jaguar XK measures about 4760 mm long (187.4 inches) and 1916 mm wide (75.4 inches), slightly narrower and roughly comparable in length. The Mercedes SL-Class is shorter and narrower, typically around 4540 mm (178.7 inches) long. The Porsche 911 is more compact with a shorter length near 4500 mm (177 inches). The DB9’s generous dimensions contribute to a spacious, comfortable cabin and impressive road presence, suiting those prioritizing both performance and luxury space.

Beyond its impressive dimensions, the Aston Martin DB9 Coupe is distinguished by its blend of performance, luxury, and craftsmanship. It features a potent V12 engine delivering smooth power, paired with a sophisticated chassis for balanced handling. The interior showcases high-quality materials like leather and wood trim, combining comfort with elegance for long-distance cruising. The DB9 also includes cutting-edge technology and bespoke customization options typical of Aston Martin. Its design ethos ensures that the car performs as a capable grand tourer—one that excels in high-speed touring with refinement, style, and exclusivity.
