Aston Martin adds ultra-luxury DBX GT SUV with 727PS V8 and a 13% quieter cabin

Aston Martin has introduced the DBX GT, a new interpretation of its acclaimed SUV that blends ultra-luxury craftsmanship, refined comfort and effortless performance. The GT expands the breadth of choice in the DBX range with what Aston Martin calls the highest levels of luxury, comfort and refinement without any sacrifice in performance. It is described as the most refined and understated interpretation of the high-performance SUV, delivering quiet luxury and elegance while keeping the on-demand dynamic capability for which the DBX is renowned. Like the DBX S, it carries the shared title of world's most powerful pure internal combustion SUV.

Front and rear seats have been redesigned with enhanced cushioning, redefined bolstering and engineered comfort curves, and a 10mm thick memory foam layer has been added to the cushion structure. A new individual rear seat layout provides two individually sculpted seating positions with extended headrests and bolsters while retaining five-seat capability, and a panoramic glass roof is standard. The cabin adds an anodised metal drive mode rotary controller and secondary switchgear with a jewellery quality finish, GT-specific monotone, duotone and tritone upholstery combinations with quilting, perforation and a stitching pattern unique to the DBX GT, plus semi-aniline leather and deep pile floor mats. Aston Martin says each front seat takes 691 metres of thread, 3,297 perforation holes and in excess of four and a half hours of craftsmanship. Targeted body-structure changes, cabin sealing, sound deadening in door panels, front and rear wheel arch zones and the rear load space, acoustic laminated rear side glass and deep pile carpets cut outside noise, producing a 13% improvement in the Articulation Index, the industry score of how easy it is to hold a conversation on the move.

The DBX GT uses the bespoke 4.0 litre twin-turbo V8 introduced on the DBX S, producing 727PS with turbocharger technology shared with the mid-engine Valhalla supercar and 900Nm of torque. Acceleration from 0-60mph takes just 3.1 seconds and top speed remains 193mph, while carbon ceramic brakes measure 420mm at the front and 390mm at the rear. A faster steering ratio shared with the DBX S sharpens agility and the turning circle remains 12.0 metres, while a revised damper calibration and a unique damper valve system manage oil flow during high-frequency, low-amplitude inputs such as coarse road surfaces or rumble strips, with spring rates that change with the selected drive mode. Throttle pedal feel and the 9-speed wet clutch automatic transmission have been recalibrated, and learnings from the Valhalla bring a new transmission mount bush plus two new longitudinal dampers between the body and rear subframe; 22-inch wheels with Pirelli Scorpion Zero All-Season tyres are standard, with 23-inch wheels on Pirelli P-Zero Summer or Scorpion Zero All-Season tyres optional. A dedicated exhaust tune uses double mixing of gas flow within the rear muffler for a cleaner, richer tone, staying discreet in GT mode and returning to full voice in Sport and Sport+ modes.
