Aston Martin has built a quieter DBX. Not a slower one, though. The new DBX GT produces 727 PS from its twin-turbocharged V8, yet the engineers have spent much of their time making sure occupants hear less of the outside world.
That sounds almost contradictory for a performance SUV. Then again, how often does anyone use 727 PS on the school run?
The DBX S already covers the aggressive side of the range. With the GT, Aston Martin is chasing customers who want the same enormous reserves of power without feeling every rough patch of tarmac.
The numbers haven’t suffered. Its four-litre V8 delivers 900 Nm, reaches 60 mph in 3.1 seconds and tops out at 193 mph. Those figures are shared with the DBX S.
What’s changed is the experience between those bursts of acceleration.
Aston Martin has revised the suspension dampers to filter small, sharp road imperfections. It has also adjusted the gearbox and throttle response, aiming for smoother progress when the driver isn’t in a hurry.
The standard 22-inch wheels wear all-season tyres chosen partly for ride comfort and reduced road noise. Buyers can still specify 23-inch wheels, although I’d want to drive both before paying extra.
Inside, the changes are easier to appreciate without a test drive.
Both front and rear seats have been redesigned, with additional cushioning and a 10 mm layer of memory foam. The rear seats are shaped more individually, while retaining the option of carrying five people.
There’s acoustic laminated rear side glass, extra insulation around the wheel arches and a panoramic roof as standard. Aston Martin claims a 13 percent improvement in its measure of speech intelligibility inside the moving car.
That’s a more interesting luxury statistic than another fraction shaved from the acceleration time. A passenger should be able to hold a conversation without raising their voice.
The exterior is deliberately restrained. A new split-vane grille, metal side detailing and body-coloured lower sections replace some of the visual aggression associated with sportier versions.
None of this makes the DBX GT discreet in an ordinary car park. It’s still a large, expensive Aston Martin SUV with four exhaust outlets.
But the thinking behind it is sensible. A car this powerful doesn’t need to remind its passengers of that fact every minute.
First deliveries are scheduled for the final quarter of 2026. The real question is whether the extra refinement makes the GT a better DBX for the journeys owners actually take.
