Aston Martin unveils DBX S: 727PS, weight reduction and bold design

Aston Martin presents DBX S with 727PS, carbon roof, and Bowers & Wilkins audio. A lightweight, high-performance evolution of its flagship SUV.

Aston Martin has unveiled its new flagship SUV — the DBX S — and it’s more than just a model upgrade. It’s a statement of intent: a bold move by the iconic brand into the world of ultra-luxury performance SUVs, redefining the boundaries of power, design, and engineering.

At the heart of the DBX S lies a re-engineered 4.0-litre twin-turbo V8, enhanced with turbocharging componentry derived from the upcoming Valhalla supercar — including larger compressor wheels and other internal refinements. The result? A staggering 727PS and 900Nm of torque, launching the DBX S from 0–62mph in just 3.3 seconds. While the top speed remains at 193mph, the sharper throttle response at the upper rev range delivers an experience designed to thrill even the most seasoned drivers.

But this SUV isn’t just about raw numbers. Aston Martin has shaved up to 47kg off the DBX707’s weight through clever engineering choices: a carbon fibre roof (saving 18kg), optional magnesium wheels (cutting 19kg of unsprung mass), and a polycarbonate honeycomb grille. Crucially, these aren’t just weight cuts — they are smart redistributions that lower the center of gravity and enhance weight balance, resulting in noticeably sharper handling and more agile cornering.

Power is delivered through a recalibrated 9-speed ‘wet clutch’ transmission, familiar from the DBX707 but refined here for an even more responsive experience. Shift points are optimized for the extended rev range, while downshifts in Sport and Sport+ modes come with added urgency, maximizing driver engagement.

Suspension upgrades introduced in 2024 carry over, with revised air springs and electronic dampers improving transient body control and ride quality. Thanks to an active anti-roll system, the DBX S limits body roll to just 1.5 degrees — a figure that rivals purpose-built sports cars — while retaining a natural, confident cornering feel.

Aerodynamically, the DBX S takes bold steps forward. A new splitter, upturned side blades, and a reprofiled rear — complete with quad vertically stacked exhausts — contribute to both form and function. The polycarbonate grille, inspired by the DBS 770 Ultimate and intricately shaped with over 25,000 facets, reinforces the SUV’s aggressive stance and technical identity.

Inside, the DBX S remains unmistakably bespoke. Standard Alcantara upholstery is seamlessly paired with semi-aniline leather in high-wear zones, while the seats feature a striking herringbone pattern that widens toward the headrests to evoke motion. Optional red seatbelts, ‘S’ embroidery, and Aston Martin wing emblems — crafted with precision embossing and debossing — elevate the interior’s tactile and visual appeal.

For audiophiles, the optional 1,600W, 23-speaker Bowers & Wilkins sound system transforms the cabin into a concert hall, acoustically tailored to the DBX S’s interior geometry and engineered with the same technologies found in Bowers & Wilkins’ world-class loudspeakers.

Continuing the storied legacy of the ‘S’ suffix — from the Vanquish S and V12 Vantage S to the Rapide S and beyond — the DBX S also subtly nods to Aston Martin’s historic DB3S of 1953, a lighter, more powerful competition car that helped define the brand’s post-war racing heritage.

With deliveries expected in Q4 2025, the DBX S doesn’t just sit at the top of the DBX range — it aims to become a new benchmark in the high-performance luxury SUV segment.
