According to executive vice president and chief creative officer Marek Reichman, the wheelbase of the DBX stretches as far out as possible for the wheels to be positioned at the corners of the vehicle, which, with the low roofline, creates the illusion of a smaller car, helping make the DBX appear more like a traditional Aston Martin shape.

The DBX features swan-hinged doors, while the front grille is the largest ever fitted on an Aston Martin.

The DBX uses Mercedes-AMG's M177 4.0-litre twin-turbocharged V8 engine that has a power output of 550 PS (405 kW; 542 hp) and 700 N⋅m (516 lb⋅ft) of torque.

An active centre transfer case directs torque to the front axle when it is required, and there is also an electronic limited slip rear differential.

Adaptive dampers and triple-chamber air springs are both standard, offering a significant range of height adjustment.

[21] Its M177 engine was slightly modified by Aston Martin and received new turbochargers with ball bearings, generating a maximum power output of 707 PS (520 kW; 697 hp) and 900 N⋅m (664 lb⋅ft) of torque.

The DBX Medical Car has a British Racing Green livery with neon yellow accents.
