The Aston Martin DBX707. SUV with supercar power and everyday focus

The Aston Martin DBX707 sits high above the tarmac, its 23?inch wheels filling the arches so tightly you almost expect to hear gravel pinging the wheel wells as it rolls past a café terrace. Inside, development boss Roberto Fedeli talks about making 707 PS feel controllable, not intimidating.

Power SUV with 707 PS

The DBX707 is Aston Martin’s performance flagship of the DBX SUV line, using a 4.0?liter twin?turbo V8 rated at 707 PS (697 bhp) and 900 Nm of torque, paired with a 9?speed wet?clutch automatic gearbox. Aston Martin quotes 0 to 100 km/h in 3.3 seconds and a top speed of 310 km/h, figures that push the large SUV firmly into supercar territory. The engine is sourced from Mercedes?AMG and then re?engineered by Aston Martin with new turbos, calibration and cooling hardware for the higher output.

Despite the headline numbers, Fedeli and his team tuned the throttle mapping and gearbox behavior so that the DBX707 can crawl smoothly in city traffic before unleashing boost on an autobahn on?ramp. An active exhaust system lets drivers switch from a relatively muted note at low revs to a harder, metallic bark when the V8 is worked, which you can clearly hear in independent track tests.

Chassis, brakes and everyday use

To keep the nearly 2.2?ton SUV in check, Aston Martin fits carbon?ceramic brakes with 420 mm front discs and 410 mm rear discs as standard, clamped by six?piston calipers. The system saves around 40.5 kg of unsprung mass versus steel brakes according to the company, helping steering precision. Air suspension with triple?chamber springs and active anti?roll control adapts damping in milliseconds, juggling comfort and body control depending on the selected drive mode.

Reviewers describe the steering as relatively light but accurate, with a firm, slightly gritty feel through the rim on rough asphalt. In the cabin, there is room for five occupants, and the rear bench folds to expand the luggage area from about 638 liters to more than 1,500 liters in a long, flat space. That duality makes the DBX707 a daily?use SUV as much as a performance toy, something CEO Lawrence Stroll repeatedly mentions when justifying the model’s development budget.

Interior, tech and customization

The DBX707’s interior mixes leather, Alcantara and metal toggle switches, with a driver position that still feels more sports car than traditional SUV according to early test drives. A central infotainment screen uses an interface based on a previous?generation Mercedes MBUX system, updated by Aston Martin with its own graphics and menus. While it lacks full touch operation in some versions, rotary and touchpad controls on the console give a tactile, analogue feel.

Standard equipment includes sports seats, a 14?speaker audio system and a suite of driver assistance systems such as adaptive cruise control and lane?keeping aids. Buyers can choose extensive Q by Aston Martin personalization, from exterior carbon packs to bespoke interior color schemes, pushing the DBX707 into six?figure territory well above its already high base price in many markets.

Position in Aston Martin’s line?up

The DBX family is Aston Martin’s only SUV line and has become central to the brand’s volume strategy since its original launch around 2020, built at the St Athan plant in Wales. The 707 variant arrived later as a more focused performance version, sitting above the standard DBX in price and output. It is offered globally, with key markets including the UK, continental Europe, the US and the Middle East, where demand for powerful luxury SUVs remains strong according to dealer reports.

Analysts point out that the DBX range broadens Aston Martin’s customer base beyond traditional two?door sports cars such as the Vantage and DB12. Families who need more space but still want a hand?built British badge now have a credible option, and that can feed later upgrades into other models as brand loyalty deepens.

Context and Aston Martin Lagonda stock

The DBX707’s combination of high pricing, strong global demand for performance SUVs and shared components with Mercedes?AMG makes it a crucial margin contributor for Aston Martin Lagonda alongside its GT and sports car lines. On the London Stock Exchange, the Aston Martin Lagonda share (ISIN GB00BN7CG237) gives investors indirect exposure to the SUV’s commercial performance without tying returns to a single model cycle.
