Aston Martin DBX GT adds a comfort-focused flagship to the SUV range with DBX S power

A comfort-focused counterpart to the DBX S

Aston Martin has introduced the DBX GT, a new variant of its SUV positioned alongside the sportier DBX S with a deliberate shift in emphasis. Rather than chasing track dynamics, the British marque has tuned this car for quiet luxury and daily refinement. Aston Martin chief executive Adrian Hallmark said in a company statement that the DBX GT is aimed at customers who prefer assured elegance over sporting aggression and demand a higher degree of luxury, delivering an ultra-luxury experience with no sacrifice in performance, as reported by WardsAuto and Automotive World. ⁴⁵

Automotive World notes the strategic logic of the variant: by offering sport and comfort versions on a common powertrain, Aston Martin widens the DBX's appeal through calibration and targeted hardware updates rather than mechanical change. Carscoops adds context, reporting that the marque's 2025 sales fell to 5,448 units from 6,030 in 2024, with DBX sales down 9 per cent to 1,717, and suggesting the GT could help lift volumes and margins. ²⁵

Unchanged performance hardware

Mechanically, the DBX GT carries over the DBX S's 4.0-litre twin-turbocharged V8, built with turbocharger technology shared with the Valhalla supercar, and a nine-speed automatic transmission driving all four wheels. Torque stands at 900Nm between 3,000 and 5,250rpm, according to Carscoops and Man of Many, with power quoted at 717hp (535kW) by those outlets. ²³

There is a discrepancy on power: Autocar India quotes the same engine at 727hp, whereas Carscoops, Man of Many and WardsAuto report 717hp. Man of Many's specification table gives 717hp at 6,250rpm. ²³⁴⁶

Acceleration and top speed figures also differ slightly between outlets. Carscoops, WardsAuto and Autocar India report a claimed 0-60mph (0-100km/h) time of 3.1 seconds, while CarExpert cites a 0-100km/h time of 3.3 seconds. All agree on a 310km/h top speed and note the GT is a roughly 2,245kg, 5.0-metre-long vehicle. ¹²⁴⁶

The carbon ceramic braking package carries over, with 420mm front discs and 390mm rears, according to CarExpert. Subtle drivability tweaks include a retuned throttle pedal and a nine-speed gearbox recalibrated for smoother low-speed shifts, per Autocar India and Man of Many. ¹³⁶

Chassis and exhaust changes for a plusher ride

Although it shares the DBX S's steering rack, the GT receives revised damper settings and Pirelli all-season tyres for a more compliant and quieter ride, CarExpert reports. Man of Many details the hardware: a unique internal damper-valve system that manages oil flow during high-frequency, low-amplitude inputs to filter vibrations from coarse surfaces, working with adaptive triple-chamber air suspension that can raise the car by up to 45mm or lower it by 30mm, plus a 48-volt electronic active anti-roll system. ¹³

Borrowing engineering solutions from the Valhalla, the GT gains a new transmission mount bush for increased stiffness and two new longitudinal dampers connecting the body to the rear subframe, Man of Many and Automotive World report. Man of Many also cites chief technology officer Ian Hoban explaining that the refinement uplift required combining small hardware upgrades with targeted chassis calibrations. ³⁵

A new GT mode alters gas flow within the rear muffler through double-mixing, reducing harsh metallic frequencies for a more discreet tone, while Sport and Sport+ modes remain for a fuller exhaust note, according to CarExpert and Man of Many. Autocar India says the dedicated exhaust tune is touted to produce a cleaner, richer tone. ¹³⁶

Practical figures remain untouched: Man of Many lists a 12.0-metre turning circle, 500mm maximum wading depth and a 2,700kg towing capacity. ³

A brighter look outside, a plusher cabin within

Visually, the GT trades the DBX's darker, more aggressive trim for brightwork. CarExpert details a dual polished and satin finish for the two-piece metal side strake, a chromed arc above the side windows, new double-vaned grille bars available in bright or dark finishes, and colour-coded lower front bumper, sills and rear diffuser. The standard 22-inch forged wheels wear a diamond-turned satin titanium finish, and the quad exhaust tips swap dark metal for bright polished outer pairs and satin-anodised inner tips. ¹

Man of Many adds that buyers can further tailor the exterior with a Satin Chrome Upper Package or Gloss Black and 2x2 Twill Carbon Fibre packs, and that Pirelli Scorpion Zero All-Season tyres are standard. An optional 23-inch wheel package, in aluminium or magnesium, dials some sportiness back in, per CarExpert and WardsAuto. ¹³⁴

Inside, redesigned front and rear seats gain more bolstering and a new 10mm-thick memory foam layer, with the outboard rear seats sculpted to hold passengers more securely, CarExpert reports. Man of Many details the craftsmanship: each front seat requires 691 metres of thread, 3,297 perforation holes and over four and a half hours of manual assembly, and GT Plus Semi-Aniline leather and Alcantara packages are offered in monotone, duotone and tritone combinations. Carscoops notes the GT uses two individual sculpted rear seats rather than the bench found elsewhere in the DBX range, while retaining a third central position and five-seat flexibility. ¹²³

A panoramic glass roof becomes standard, anodised metal appears on the drive mode dial and switchgear, and deep-pile floor mats are fitted, CarExpert reports. The technology suite includes a 10.25-inch central touchscreen, a 12.3-inch driver display, 64-colour dual-zone ambient lighting and a Bowers & Wilkins audio system, according to Man of Many. ¹³

Quieter cabin, measured in numbers

Aston Martin claims the sound-deadening work — acoustic laminated rear side glass, more precise sound deadening placement in the doors, extra material in the wheel arches and deep-pile carpets — delivers a 13 per cent improvement in the Articulation Index, the industry measure of how easily occupants can hold a conversation on the move. This claim is reported consistently by CarExpert, WardsAuto, Man of Many and Automotive World, with WardsAuto noting the index also applies to phone calls made through the Bowers & Wilkins system. ¹³⁴⁵

Pricing and availability

Aston Martin has not announced market-specific pricing for the DBX GT, and first customer deliveries are scheduled to begin in the fourth quarter of 2026, according to Carscoops. Autocar India and CarExpert likewise report global availability beginning in Q4 2026. ¹²⁶

In the United States, WardsAuto reports that no sticker price has been confirmed, but quotes a factory press spokesperson's email saying that while pricing is not confirmed, speculation at $262,000 is welcome. WardsAuto also notes the DBX S currently retails from around $276,500 in the US, with options quickly pushing beyond $300,000 — figures from that publication, not Aston Martin. ⁴

For Australia, official pricing has not been announced. Man of Many observes buyers can expect the GT to carry a premium to the existing DBX range, which that publication says starts at AUD$475,000 before on-road costs, with the final drive-away price dependent on options and configuration. ³
