Aston Martin DBX707 has a price tag of $428,000
CLAIMED as the “fastest, most powerful, best-handling and most engaging car of its kind”, the new range-topping Aston Martin DBX707 has been designed to “take Aston Martin to the pinnacle of SUV performance” – and it is expected to arrive Down Under late in the second or early third quarter of this year.
Aston Martin confirmed GoAuto News the newcomer will cost $428,400 (excluding ORC).
These bold claims about the DBX707 were made by Aston Martin CEO (and former Mercedes-AMG boss) Tobias Moers. The newcomer, whose nomenclature is derived from its 707PS output, may look like a limited edition model, but no, it’s the flagship of the range.
The DBX707 is clearly aiming to eclipse the Lamborghini Urus and the upcoming Ferrari Purosangue super SUVs.
For starters, Mercedes-AMG’s 4.0-litre twin-turbo V8 has been beefed up with ball-bearing turbochargers and bespoke engine tuning to produce peak outputs of 520kW and 900Nm – increases of 46 kW and 200 Nm compared to the V8 engine. DBX.
The potent engine is compared to a nine-speed wet multi-clutch automatic transmission, which is said to be able to handle much higher torque loads – and offer noticeably quicker gear changes – compared to the converter box of DBX standard torque.
Aston Martin claims the DBX707 can go from zero to 100 km/h in 3.3 seconds, compared to 4.5 seconds for its sibling.
The DBX707 also features an updated electronic limited-slip rear differential with a shorter final drive ratio of 3.27 compared to 3.07 for the DBX V8. This is said to help the DBX707’s sprint ability through lower gears and improve in-gear response.
Front-to-rear torque distribution remains fully automatic, with the ability to send up to 100% of torque to the rear axle on demand.
To aid in the absolute handling of the air-sprung Aston Martin, the Gaydon-based marque has implemented dedicated chassis tuning. The DBX707 features a new damping valving and recalibration of the dynamic spring volume switching. Additionally, the electronic power steering system has also been tweaked to improve steering feel, with “greater off-center effort buildup,” the firm says.
Combined with tighter handling of lift (vertical movement over bumps and crests or in compressions), pitch (when the car dives under braking or squats under acceleration) and body roll, the DBX707 is supposed to offer the driver “an easier ability to adjust the yaw of the car with natural pedal or steering inputs”.
The eARC (Electronic Active Roll Control) system, for its part, has revised parameters which “reinforce the feeling of agility and improve the dynamic balance of the car”.
For optimum stopping power, the newcomer is fitted as standard with carbon ceramic brakes (420 mm discs at the front and 390 mm discs at the rear), which are gripped by six-piston calipers and allow a 40.5 kg reduction in unsprung weight. Aided by improved cooling, hydraulic brake system sizing and booster tuning improve pedal feel and braking response.
From an aesthetic point of view, the execution of the front end of the DBX707 is distinguished by its enlarged satin chrome grille (with double vanes and six horizontal bars), the revised daytime running light signature, as well as new air intakes , brake- cooling ducts and front splitter profile.
Other derivative-specific adornments include new louvered hood blades, dark satin chrome window surrounds and gloss black side sills, while at the rear the DBX707 features a new spoiler, a redesigned rear bumper that features integrated quarter-panel vents, a significantly enlarged Dual Rear Diffuser as well as quad big-bore exhaust tips (finished in Satin Black).
Inside, Aston Martin’s newcomer comes standard with dark chrome-finished switchgear, piano black veneer with sports front seats that offer 16-way power adjustment. A heating function is available for the front and rear occupants.
A mix of leather and Alcantara trim is standard, but semi-aniline leather with embroidered Aston Martin wings on the headrests, contrast stripes down the center of the seats and a perforation pattern in the seat backs and cushions seats is optional.
The revised lower console contains new drive mode selector switches (in the DBX707, “Race Start” is available in GT Sport as well as Sport+ modes). These include dedicated buttons for suspension mode, ESP, manual gear selection mode and an active exhaust switch, which opens the valves of the four-outlet sports exhaust system without the need for be in Sport driving mode.
Finally, for customers who wish to personalize their DBX707, Q by Aston Martin – the brand’s bespoke service – offers a wide range of options at additional cost, ranging from unique graphics to tinted carbons and bespoke materials both inside and outside the SUV, the company says.
