Aston Martin DBX 707 2022: loads more power and extra performance for range-topping British SUV

---

Aston Martin has gone above and beyond to create a ballistic version of its relatively fresh DBX SUV, tinkering with the engine, transmission, brakes and differential to produce a battletruck worthy of taking on the most outrageous SUVs on the planet. 

With significant improvements made to all these key areas, the result is one of the fastest and most powerful SUVs ever – the Aston Martin DBX 707. 

Production for the DBX 707 is due to commence in the first quarter of 2022, with overseas deliveries scheduled for early in the second quarter of 2022. 

Australian-market DBX 707 arrivals are yet to be confirmed. 

Performance enhancements on the DBX 707

The team at Aston Martin clearly didn’t think the existing DBX’s 4.0-litre twin-turbo V8 was powerful enough, so they added new ball-bearing turbochargers and more focused engine calibration to liberate even greater outputs from the legendary AMG-sourced unit. 

A new nine-speed wet-clutch automatic transmission will debut for the first time in the SUV, which can now handle the extreme forces of 519kW (707PS, hence the name) and 900Nm produced by the engine. That’s a serious 115kW/200Nm increase from the far-from-slow standard DBX. 

The DBX 707 can now launch from 0-100km/h in a claimed 3.3 seconds, making it one of the fastest SUVs on the planet. For reference, the Jeep Grand Cherokee Trackhawk does the same sprint in 3.5 seconds. The DBX 707 is now more powerful than a Lamborghini Urus and only 3kW shy of the supercharged Trackhawk. 

The DBX 707 also features a new version of the electronic rear limited-slip differential which now has shorter final drive ratios. Aston Martin says that 100 percent of available torque can be sent to the rear axle if needed. 

Suspension and brake upgrades

As well as additional power from the twin-turbo V8, the brakes have been upgraded to carbon-ceramic units which measure 420mm at the front and 390mm at the rear. These lighter brakes have resulted in a 40.5kg reduction in unsprung weight on the DBX 707.

Air suspension remains on the DBX but a dedicated chassis tune has been developed for the 707 edition. Aston Martin says the tuned suspension now has “tighter management of heave, pitch and body roll” than before. 

Exterior and interior refinements 

The DBX 707 is not just about more performance – it’s also about refined design and practicalities.

On the outside, the DBX 707 receives a larger front grille and new DRL lighting design, the former of which now contains restyled cooling and air ducts to help feed the high-performance V8. Dark-chrome window surrounds, bonnet blades and gloss-black side sills are also new for the DBX 707.

On the rear of the car, a new lip spoiler has been added to reduce lift and increase high-speed stability, according to Aston Martin. The rear diffuser has also been redesigned to accommodate a larger-diameter quad exhaust system, which has been tuned to give “a unique sound signature”. 

Inside, sports seats are fitted as standard (with comfort seats available as a no-cost option) with 16-way electric adjustment, plus heating in the front and rear. 

Three choices of interior trim are available including the standard fit Accelerate level which features a mix of leather and Alcantara. Comfort and Inspire Sport trims both feature semi-aniline leather with embroidered Aston Martin wings on the headrest. 

Bespoke options can be created through Aston Martin’s Q department, which sounds very James Bond to us.
