Aston Martin DBX - SUV - Powertrain Highlights:
New evolution of the 4.0-litre, Twin-Turbo V8 found in Vantage and DB11
Outputs of 550 PS and 700 Nm provide exhilarating levels of performance
Active exhaust delivers sound and character of a sports car
9-speed automatic gearbox calibrated to the unique requirements of DBX

Adaptive triple volume air suspension has been combined with the latest 48v electric anti-roll control system (eARC) and electronic adaptive dampers to provide the new SUV with a huge breadth of ability. With its capacity to raise the ride height by 45mm or lower it by 50mm the air suspension gives any driver the confidence to tackle a wide range of terrain. While this of course provides benefits while on the move, the system can be further programmed to aid with ingress, egress and loading requirements, aiding on a practical level.

The adaptive triple chamber air springs enable variable spring stiffness, giving both luxurious comfort and dynamic prowess. Extraordinarily the eARC – capable of 1,400Nm of anti-roll force per axle – can limit DBX’s body roll for handling that is much more akin to that of a sports car than an SUV. This sophisticated system of adaptive air suspension, dampers and eARC allows for maximum ride comfort when transporting up to five occupants and their luggage, while maintaining a highly responsive and engaging dynamic capability.

Powered by a new version of the characterful 4-litre, twin-turbocharged V8 engine found in DB11 and Vantage, DBX features an impressive output of 550PS and 700NM of torque, carefully tuned to meet the specific needs of this model. With a sound character that is unquestionably Aston Martin, the active exhaust system ensures this is a luxury SUV that can sound refined one moment and exhilarating the next. The engine’s versatility isn’t restricted to its vocals either; the turbocharged V8 has cylinder deactivation to enhance fuel economy, yet it can also propel DBX from 0 to 62mph in 4.5 seconds and on to a top speed of 181mph.
