Every Aston Martin DBX generation, measured
One row per generation. Watch the weight column — that is where most of the change happens for the Aston Martin DBX, 0 lb of it since 2020, and it is the number that decides fuel use, tyre wear and how far the car takes to stop.
| Generation | Length | Width | Height | Wheelbase | Curb weight |
|---|---|---|---|---|---|
| 2020–2026 | 198.4″ | 78.7″ | 66.1″ | 120.5″ | 4,949 lb |

Will a DBX fit
The practical question behind every dimensions search, and for a 16.5-foot Aston Martin DBX it has a straight answer. A single-car garage in the US is typically 20 feet deep and a street parking space about 18, so the DBX clears the garage by 2.5 ft. We allow a foot of clearance in both — nobody parks to the millimetre.
| Space | Typical size | This car | Verdict |
|---|---|---|---|
| Single garage | 20 ft deep | 16.5 ft | Fits, with room to open the door |
| Street parking space | 18 ft | 16.5 ft | Fits comfortably |
| Standard parking bay width | 8.5 ft wide | 6.6 ft | Room to open doors both sides |
Against cars of the same length
Compared with 767 vehicles within ten inches of the same length — a fair proxy for «cars of this size», regardless of what the marketing calls them.
| Measure | This car | Typical car of this length | Difference |
|---|---|---|---|
| Width | 78.7″ | 74″ | +4.7″ |
| Wheelbase | 120.5″ | 114.6″ | +5.9″ |
| Curb weight | 4,949 lb | 4,167 lb | 782 lb |
A longer wheelbase for the same overall length means shorter overhangs — usually more cabin space and a steadier ride. At 4,949 lb the Aston Martin DBX is 783 lb heavier than typical for its size, which generally shows up as fuel economy and stopping distance.

How we measure
Dimensions come from NHTSA vPIC and Transport Canada vehicle records — manufacturer-declared figures, held in metric and converted to inches and pounds for display, 7 measured model years for the Aston Martin DBX between 2020 and 2026.
One row per generation, not per model year: manufacturers rarely change the body between facelifts, and the Aston Martin DBX fits into 1 rows instead of 7. Where a generation offered several body styles, the figures are the base measurements for that generation of the Aston Martin DBX.
