2020 Aston Martin DBX Dimensions, Size & Specs

The curb weight of the Aston Martin DBX ranges between 2198 kg to 2245 kg (4847 to 4950 lbs), depending on trim and equipment. The maximum permissible weight, which includes passengers, cargo, and additional equipment, is rated at 3020 kg (6656 lbs). This weight range reflects the DBX’s robust construction, luxury features, and performance components. The relatively high maximum weight also ensures the vehicle’s stability and safety under full load conditions, in line with luxury SUVs designed for both everyday usability and spirited driving.

The Aston Martin DBX offers a ground clearance of 190 mm (7.5 inches). This ride height strikes a balance between luxury on-road comfort and limited off-road capability. While the DBX is primarily designed for sporty on-road driving and luxury cruising, the 190 mm ground clearance provides enough space to handle rough urban paths, mild off-roading, or uneven terrain that a typical SUV might face. It also supports a smooth ride quality without compromising the vehicle’s dynamic handling characteristics, making it versatile for daily use and light adventurous excursions.

The Aston Martin DBX features a spacious luggage capacity ranging between 632 to 638 liters (22.3 to 22.5 cubic feet), making it one of the more generous cargo spaces in its luxury SUV class. This volume can comfortably accommodate multiple suitcases, sports equipment, or groceries, enhancing its practicality for daily activities and long road trips alike. The design cleverly integrates this cargo space without compromising passenger comfort, allowing for a versatile cabin setup. The rear seats can be folded to further increase cargo capacity as needed, catering to families or individuals with active lifestyles.

Given the Aston Martin DBX’s dimensions, it generally fits into a standard garage but with limited clearance. Standard residential garages are typically about 2438 mm (8 feet) wide and 4877 mm (16 feet) deep. With the DBX's width ranging from 1998 mm (78.7 inches) to a maximum 2220 mm (87.4 inches) including mirrors, and a length of 5039 mm (198.3 inches), it will fit in most garages lengthwise but may be a tight fit in width, especially when mirrors are open. Drivers should fold mirrors to reduce width to approximately 1998 mm (78.7 inches) for safer parking. Height at 1680 mm (66.1 inches) poses no issues for standard garage door clearance.

The Aston Martin DBX’s width varies significantly depending on the positions of its side mirrors. With mirrors folded, the width ranges from 1998 mm (78.7 inches) up to 2150 mm (84.6 inches), whereas with mirrors fully opened, it extends between 2175 mm to 2220 mm (85.6 to 87.4 inches). This variability is crucial for practical purposes such as navigating narrow streets, parking in tight spaces, and fitting into garages or parking structures. Folding the mirrors reduces the DBX’s footprint and minimizes the risk of damage. Thus, drivers should be aware of these width variations especially in urban environments or confined spaces.

The Aston Martin DBX is Aston Martin’s first SUV model, introduced in 2020, so it does not have a direct predecessor SUV from the brand for dimensional comparison. Compared to Aston Martin’s sports cars and grand tourers—which are typically lower, narrower, and shorter—the DBX is significantly larger in all dimensions to accommodate a more practical, versatile SUV design. It introduces a new segment for Aston Martin, blending the brand’s signature luxury and performance with SUV functionality. Its size aligns well with other luxury SUVs, providing a fresh and competitive option within this segment.

The Aston Martin DBX stands tall in the luxury SUV segment with a length of over 5 meters (5039 mm / 198.3 inches), width up to 2220 mm (87.4 inches) with mirrors opened, and a curb weight exceeding 2200 kg (4850 lbs). Compared to rivals like the Bentley Bentayga or Lamborghini Urus, the DBX offers similar interior space and cargo capacity, making it competitive size-wise. However, the DBX distinguishes itself through its blend of traditional Aston Martin design cues, handcrafted luxury, and sporty driving dynamics. Its ground clearance of 190 mm (7.5 inches) provides adequate capability for light off-road conditions, placing it comfortably within the segment’s expectations.

The Aston Martin DBX comes with multiple tire and rim size options to optimize performance and aesthetics. Rim sizes include 11.5J x 22, 10J x 22, 11.5J x 23, and 10J x 23 with offsets (ET) of 48 to 56. Tire sizes vary accordingly: 325/35 YR22, 285/40 YR22, 325/35 R22, 285/40 R22, 325/30 ZR23, and 285/35 ZR23. Larger rims and wider tires enhance road grip, stability, and cornering performance, while smaller setups improve ride comfort and off-road agility. These configurations allow owners to prioritize sporty handling or a smoother ride based on their driving preferences and conditions.

The roof load capacity of the Aston Martin DBX is rated at 75 kg (approximately 165 lbs). This limitation means the vehicle can safely carry roof boxes, bike racks, or other lightweight equipment, providing flexibility for outdoor activities or extended trips. It is important to adhere to this maximum to maintain driving stability and avoid damage to the roof structure. The DBX’s roof capacity is typical for luxury SUVs and balances structural integrity with versatility, making it practical enough for the needs of most SUV users who may require additional cargo space beyond the generous internal luggage compartment.
