What engine does the Aston Martin DBX use?

A 4.0-litre twin-turbo V8 sourced from Mercedes-AMG (M177 series, also used in the GT 63 and S 63), producing 405kW and 700Nm. Paired with an 8-speed ZF automatic and permanent all-wheel drive.

How does the DBX compare to a Bentley Bentayga?

The DBX undercuts the Bentayga V8 by around $40,000-$60,000 with similar performance (4.5s vs 4.4s 0-100) and a more sports-car-tuned chassis. The Bentayga has a more lavishly trimmed cabin and a wider AU dealer network. Choose the DBX if you want the sharpest-driving luxury SUV; the Bentayga for cabin opulence.

Is the Aston Martin DBX ANCAP rated?

No. Aston Martin has not submitted the DBX for ANCAP crash testing. It carries a 3-year unlimited-kilometre AU warranty.
