The verdict

What's good

  • 717 hp makes it the fastest-accelerating production SUV Aston has ever built
  • Bespoke Q-division customization options are broader than any German rival offers
  • Rear cabin height and legroom rival dedicated luxury saloons in this price range
  • Aston's Sweetcroft Lane chassis tuning keeps body roll genuinely controlled for the weight

What's not

  • Aston Martin's historical electrical reliability raises long-term ownership questions
  • Sport+ drive mode stiffens the ride noticeably on British B-roads and urban potholes
  • Fuel consumption in spirited driving can exceed 15 L/100km regularly
  • Twin-turbo V8 is shared across multiple Aston models, lacking DBX S exclusivity

The engine

4.0L Twin-Turbo V8

4.0L Twin-Turbo V8

Aston's 4.0-liter twin-turbo V8 trades the old naturally-aspirated bellow for savage, hot-vee turbocharged thrust — re-tuned with bespoke intake, exhaust and software to sound and feel unmistakably Aston.

Sourced from Mercedes-AMG in Affalterbach as part of a technical partnership, then re-engineered by Aston Martin to suit the lighter, more agile character of cars like the Vantage and DB12.
