Aston Martin has expanded its SUV range with the DBX GT, a version aimed in a different direction from the more aggressive DBX S. It keeps the performance of Aston's most powerful combustion-only SUV specification while adding a quieter cabin, a more restrained appearance and chassis tuning intended to make everyday driving more comfortable.
The DBX GT uses the same 4.0-litre twin-turbo V8 introduced in the DBX S. Its 727 PS output is equivalent to about 717 hp, with 900 Nm of torque. Aston Martin claims a 0-60 mph time of 3.1 seconds and a top speed of 193 mph. The engine uses turbocharger technology shared with the mid-engined Valhalla, while carbon-ceramic brakes measure 420 mm at the front and 390 mm at the rear.
The more significant work is in refinement. Aston Martin has fitted revised damper calibration and a new internal valve system designed to filter high-frequency, low-amplitude inputs such as coarse road surfaces. Standard 22-inch forged wheels wear all-season tyres chosen partly for ride compliance and reduced road noise. Throttle response, the nine-speed wet-clutch automatic transmission and the exhaust have also been recalibrated to give the GT mode a smoother, less abrupt character.
Inside, the front and rear seats are redesigned with additional cushioning, revised bolsters and a 10 mm memory-foam layer. A new rear-seat arrangement uses two individually sculpted seating positions while retaining five-seat capability. Semi-aniline leather, deep-pile carpeting and more elaborate embroidery are part of the specification.
Aston Martin says targeted sound insulation, improved sealing and acoustic laminated rear side glass have produced a 13 percent improvement in its Articulation Index measure, which evaluates how easily occupants can hold a conversation while the car is moving.
Exterior changes include a new double-vaned grille, two-piece metal side strakes, body-colour lower trim and four horizontally arranged exhaust finishers. The result is intended to be the quieter, more discreet member of the DBX family rather than another track-inspired derivative. First deliveries are scheduled for the fourth quarter of 2026.
