Gizmo Score

We score the fuel economy of the 2022 Aston Martin DBX based on how well it fares when compared to other vehicles of its year. An average or standard score is 50.

Many factors are considered, such as the vehicle’s category, power, weight, and engine size (relative to other vehicles). For example, if a full-size pickup truck and a small sedan both do 25 MPG, the full-size pickup truck will typically have the higher score. This is because 25 MPG is considered excellent gas mileage for a pickup truck, but bad gas mileage for a small sedan.

All factors are not weighed equally, however. Most points go towards the fuel economy relative to all vehicles.
