Overview
The 2026 Aston Martin DBX S is the brand’s new flagship SUV. It follows the DBX707 but raises the stakes with added power, sharper dynamics, and extensive hardware upgrades. Built to deliver supercar-level acceleration in a luxury SUV format, the DBX S isn’t just faster—it’s engineered for more precise control, greater durability, and long-distance comfort.
Powertrain: Twin-Turbo V8 With AMG Roots
The DBX S runs a 4.0-liter twin-turbocharged V8 engine sourced and modified from Mercedes-AMG’s M177 power unit. Engineers upgraded the turbos, revised the intake system, and recalibrated the fuel mapping to push output to:
- 717 horsepower at 6,250 rpm
- 664 lb-ft of torque between 3,000–5,250 rpm
These gains translate into track-level straight-line performance:
| Performance Metric | DBX S |
|---|---|
| 0–60 mph | 3.1 seconds |
| 0–62 mph (100 km/h) | 3.3 seconds |
| Top Speed | 193 mph |
| 0–124 mph (200 km/h) | 11.4 seconds |
The SUV sends power through a 9-speed wet-clutch automatic transmission—a significant improvement over the torque-converter setup in the standard DBX. Gear changes feel tighter and quicker, improving launch consistency and mid-range acceleration.
Drivetrain and Chassis: Sharper, Smarter, Faster
Aston Martin retained the all-wheel-drive system but made it more adaptable. The system can push 100% of torque to the rear wheels, allowing more dynamic handling in Sport+ mode.
- 48-volt active anti-roll control
- Electronic limited-slip rear differential
- 4% quicker steering rack than DBX707
- Revised rear subframe for increased stiffness
The DBX S rides on an adaptive triple-chamber air suspension that adjusts dynamically to road conditions and driving modes. The setup minimizes pitch, improves ride quality, and enhances cornering stability.
Braking and Weight Reduction
The SUV uses carbon-ceramic disc brakes:
- Front: 420mm
- Rear: 390mm
These save nearly 90 lbs (41 kg) over traditional setups. Combined with 23-inch magnesium alloy wheels, the result is better stopping power and less unsprung mass.
