Aston Martin Unveils 707 bhp DBX S With More Power And Less Weight

Aston Martin is raising the bar once again in the ultra-luxury performance SUV segment with the introduction of the 2026 DBX S. Building on the foundation laid by the DBX 707, the new flagship model receives modest but targeted upgrades to power, performance, and design. The DBX S emerges following the discontinuation of the standard DBX, which featured a 534 bhp version of the twin-turbocharged 4.0-litre V8.

At the core of the DBX S is a revised version of Mercedes-AMG’s familiar twin-turbocharged 4.0-litre V8, now tuned to deliver 707 bhp —20 more than the DBX 707. The gain comes courtesy of turbocharger upgrades derived from the Valhalla hypercar. Torque remains unchanged, and while the 0–100 kmph time is still 3.1 seconds, acceleration to 200 kmph is marginally quicker, and the top speed remains capped at 311 kmph. Despite the modest increase in output, Aston Martin says driving dynamics have improved through recalibrated shift programming and steering enhancements. The 9-speed automatic transmission now offers quicker, firmer gear changes in Sport and Sport+ modes. Steering ratio is slightly faster, promising more responsive handling.

Visually, the DBX S adopts a more aggressive stance, beginning with a revised front fascia that incorporates a deeper splitter. At the rear, a cleaner diffuser design is complemented by a new stacked quad exhaust layout—vertical dual tips on each side evoke the design language of the Lexus IS F. Interior revisions are limited primarily to new trim choices and "S" badging. Standard equipment and overall layout remain largely the same as the DBX707, with Aston Martin continuing to emphasize a blend of performance and luxury.

While the DBX S can be outfitted with a suite of lightweight components, none come as standard. A new set of 23-inch magnesium wheels, claimed to be the first of their kind fitted to an SUV, reduce unsprung mass by 18 kg compared to the aluminium counterparts. A carbon fibre roof—the largest single carbon piece Aston Martin has ever installed—further contributes to weight savings, as does a honeycomb-style front grille derived from the DBS 770 Ultimate. Additional carbon fibre parts, such as mirror caps and door sills, are also available. In total, the weight-saving package can shave just over 45 kg, reducing the curb weight of the DBX S to 2198 kg. However, these reductions come at a cost, and buyers must opt for them individually.

Aston Martin has not yet disclosed pricing for the DBX S or its available options. However, with the 2025 DBX707 already starting around $260,000 (approx. ₹2.19 crore), industry expectations place a fully equipped DBX S well north of $300,000 (approx. ₹2.53 crore). Magnesium wheels, carbon body panels, and other bespoke materials typically command significant premiums in the ultra-luxury market.
