2026 Aston Martin DBX S: A New Apex in High-Performance Luxury SUVs

Aston Martin has long been synonymous with refined British performance, but the brand’s path into the realm of luxury SUVs has been one of both daring ambition and precise execution. In 2020, when the company launched the original DBX, it marked a turning point not just for Aston Martin, but for the ultra-luxury automotive segment as a whole. The DBX was not merely a response to shifting market demands—it was a statement. A declaration that utility, elegance, and raw performance could coexist harmoniously under one roof. It didn’t take long for the DBX to establish itself as a worthy rival to the likes of the Lamborghini Urus, Bentley Bentayga Speed, and Porsche Cayenne Turbo GT.

Over the years, the DBX evolved rapidly. In 2023, Aston Martin unveiled the DBX 707, a high-performance variant boasting 697 horsepower and a chassis that could go toe-to-toe with supercars while offering everyday practicality and long-distance comfort. But now, for 2026, Aston Martin has turned up the volume again—both literally and metaphorically. Enter the DBX S, a more potent, more focused, and lighter version of the already ferocious DBX 707. It’s a model that doesn’t merely seek to outperform its predecessor—it aims to redefine the limits of what a luxury performance SUV can be.

The Power Within: 717 Horses of Refined Fury

Under the hood, the 2026 DBX S retains Aston Martin’s tried-and-true 4.0-liter twin-turbocharged V8 engine, developed in partnership with Mercedes-AMG. However, this engine has undergone significant internal enhancements inspired by the brand’s upcoming Valhalla supercar. Among the most notable changes are the enlarged turbocharger compressor wheels and a series of undisclosed "internal improvements" aimed at maximizing airflow, combustion efficiency, and response.

These refinements have resulted in an increase of 20 horsepower, bringing the total output to a thunderous 717 horsepower. While the torque figure remains similar to the 707’s 663 lb-ft, the engine’s delivery is sharper and more responsive. According to Aston Martin, the DBX S can now accelerate from 0 to 62 mph in a mere 3.3 seconds, with a top speed holding steady at 193 mph. But acceleration is only part of the story. Aston claims the DBX S is 0.3 seconds quicker to 124 mph than the DBX 707, pointing to significant improvements in mid-range and high-speed performance.

It’s important to note that Aston Martin tends to be conservative with its performance estimates. In independent testing, the DBX 707 sprinted from 0 to 60 mph in just 3.1 seconds, and it’s highly likely that the DBX S will be even quicker under the right conditions. But it’s not just about straight-line speed—the DBX S is designed to thrill on the track, the backroads, and everywhere in between.

Sharper, Faster, Smarter: Transmission and Dynamics Reworked

Beyond the engine, Aston Martin has fine-tuned several critical systems to elevate the DBX S’s driving experience. It retains the sophisticated all-wheel-drive system of the 707, capable of sending up to 100% of the available torque to the rear wheels, or splitting it 50/50 between front and rear for maximum traction when needed. This intelligent torque distribution, combined with a rear electronic limited-slip differential, enables the DBX S to maintain composure and deliver power with grace—whether carving canyon roads or attacking a tight apex on a mountain pass.

The nine-speed automatic transmission has also been recalibrated. Downshifts in Sport and Sport+ modes are now quicker and more aggressive, delivering punchier throttle response and crisper engagement. Meanwhile, upshifts have been optimized to match the engine’s new, slightly extended rev range. This results in a more connected, intuitive driving experience that rewards spirited driving.

Further enhancing the emotional connection between driver and machine is a reworked exhaust system. While Aston Martin has always prioritized acoustic pleasure, the DBX S takes it a step further. The redesigned exhaust amplifies the distinctive roar of the V8, especially under load. At full throttle, it delivers a deeply satisfying growl that builds into a high-revving crescendo—reminding you that this SUV shares its soul with the likes of the Vantage and DB11.

Lighter, Leaner, Louder: Weight Savings and Optional Upgrades

If the DBX S is a study in refinement, it’s also one in reduction. Aston Martin engineers sought every opportunity to trim fat and enhance agility. Though the standard DBX S is already impressively balanced, those looking to shave off every last ounce can opt for a suite of weight-saving components.

Leading the charge is the new carbon-fiber roof—a single, sweeping panel that becomes the largest carbon-fiber piece ever fitted to an Aston Martin production vehicle. Not only does it lower the center of gravity, but it also saves a substantial 39.7 pounds. It’s worth noting that this upgrade also necessitates the removal of the roof rails, enhancing the DBX’s sleek, coupe-like silhouette.

Buyers can also choose forged magnesium wheels, a rare feature in the SUV world. These wheels cut 42 pounds of unsprung mass, significantly improving ride quality and handling response. When combined with the carbon roof and lightweight brake options, the DBX S can shed nearly 100 pounds compared to the standard configuration—a meaningful difference that translates directly to performance.

Subtle Yet Purposeful: Exterior and Interior Enhancements

Visually, the DBX S builds on the aggressive design language of the 707, but with subtle refinements that speak to its elevated status. The front fascia remains dominated by Aston Martin’s signature gaping grille, flanked by angular intakes and reshaped LED headlamps. However, the air intakes are reworked for improved cooling and airflow, while the lower splitter is slightly extended for added aerodynamic stability.

At the rear, the quad exhaust tips are finished in dark chrome, subtly hinting at the beast within. A revised diffuser and body-colored aero elements add visual width and reduce turbulence at speed. The overall aesthetic is one of restrained aggression—an SUV that looks fast even when standing still.

Inside, the DBX S is an exercise in bespoke craftsmanship. Rich leather, alcantara, and open-pore wood or carbon-fiber trim dominate the cabin. Aston Martin’s latest infotainment system—shared with its new generation of sports cars—offers sharper graphics and a more intuitive interface. The Sport+ seats, which come standard, offer enhanced lateral support without compromising long-distance comfort.

Buyers can customize every detail of the interior through Q by Aston Martin, the company’s in-house personalization division. Whether it’s unique color schemes, monogrammed upholstery, or hand-painted veneers, the DBX S offers virtually limitless possibilities to make the vehicle truly your own.

Where the DBX S Stands in the Market

The high-performance SUV segment has exploded in recent years, and Aston Martin is acutely aware of the competition. The Lamborghini Urus Performante, with its 657-hp V8 and track-focused tuning, is a close rival, as is the Porsche Cayenne Turbo GT, which excels in chassis balance and Nürburgring lap times. Then there’s the Ferrari Purosangue, which delivers V12 character but at a significantly higher price point.

Yet, the DBX S stands apart by offering a uniquely Aston Martin blend of elegance, power, and exclusivity. It doesn’t scream for attention like the Urus, nor does it attempt to be a sports car in SUV clothing. Instead, it confidently occupies a middle ground, delivering supercar thrills in a grand touring package, with room for five and the ability to cross continents in style.

Final Thoughts: A Super SUV Without Compromise

The 2026 Aston Martin DBX S is not just a logical evolution of the DBX lineup—it’s a bold statement of intent. It captures everything enthusiasts love about Aston Martin: a sonorous engine, captivating design, and meticulous craftsmanship—while offering genuine practicality and real-world usability. It’s a vehicle that blends raw emotion and refined engineering, thrilling the senses while cocooning its occupants in a world of luxury.

With 717 horsepower underfoot, improved dynamics, and options that make it lighter and sharper than ever, the DBX S isn’t merely competing in the luxury SUV space—it’s redefining it. And in doing so, Aston Martin has once again proven that it knows how to deliver drama, elegance, and speed in equal measure.
