A new seat of power
The DBX707 combines all of the performance you’d expect from an Aston Martin with incredible handling and a great deal of comfort.
Need to know
The DBX707 is one of the most powerful production SUVs ever made thanks to its 4.0-litre twin-turbocharged V8 engine
The 707 in the DBX707’s name refers to its output in PS, which equates to 697bhp
Aston Martin has extensively upgraded the DBX707’s chassis over the regular car, including upgrades for the suspension, brakes and transmission.
What we think
“The DBX707 is at the cutting edge of performance SUVs, bringing the kind of experience you’d expect from a supercar but in a usable and convenient layout. As a car that’ll both exhilarate and prove dependable on a daily basis, the DBX707 really delivers."
Aston Martin didn’t just look to add more power to the DBX in its evolution to 707. Far from it, this car has been comprehensively reworked to make it even sharper to drive. As well as an upgraded engine, the new Aston Martin DBX707 incorporates a nine-speed ‘wet clutch’ automatic transmission, which can better handle the increased torque levels developed by the 4.0-litre V8 under the bonnet.
This new transmission brings faster shifts while improving its launching ability to ensure an impressively quick 0-60mph time of just under 3.3 seconds. Aston Martin has also included standard-fit carbon ceramic brakes, which benefit from improved cooling and high-performance brake pads designed to operate even at very high temperatures.
The standard DBX is already a fine-looking vehicle, so how do you take its design one step further? Well, Aston Martin started by incorporating a larger front grille with new air intakes and brake cooling ducts, which help to channel more air to key components while giving the car a more aggressive appearance. That chrome grille now features double vanes and six horizontal bars which help to differentiate it from the standard DBX.
Around the back, a new lip spoiler has been added to the top of the roof to help improve high-speed stability, while the twin rear diffuser is larger to incorporate the new quad exhaust system.
The interior technology that you get in the DBX707 is much the same as you will on the regular DBX, which is a good thing indeed. Things are centred around a 10.25-inch central screen, controlled via a rotary dial to access functions such as satellite navigation and media. It also incorporates Apple CarPlay, so you can quickly and easily mirror your smartphone’s display on the car’s main screen.
This is then backed up by a 10.25-inch display sitting in the place of the conventional dials. It’s clear and easy to read and can be configured to show different layouts and information. The DBX707’s lower centre console area has been tweaked over the one in the standard DBX, giving quicker and easier access to the driver modes.
Engines & Performance
The very core of the DBX707 is its 4.0-litre twin-turbocharged V8 engine. Immensely powerful, it brings 697bhp and 900Nm of torque - hikes of 155bhp and 200Nm over the regular DBX. Though the same engine as the standard car, the DBX707’s V8 has been extensively reworked in order to free up that extra power, with ball-bearing turbochargers and a bespoke engine calibration setup included.
Electronic Active Roll Control allows the DBX707 to remain even flatter through the bends, while the new quad exhaust system has an active switch which allows it to be relatively muted for driving around town, but will enable the engine to go into full song when driving more enthusiastically.
Despite being a relatively large SUV, the DBX707 is accompanied by a set of statistics that are more in keeping with a supercar. It’ll manage the 0-60mph sprint in under 3.3 seconds and can carry on to a top speed of 193mph. This super-fast acceleration time comes through the tweaking of the DBX’s launch control, which is now even sharper and more focused in its use on the 707.
The DBX707 also includes a revised limited-slip differential that has been strengthened to handle all of that extra torque, while 100 per cent of that power can be sent to the rear wheels alone when required for a more spirited driving experience. Despite all of this performance, the Aston Martin DBX707 should still manage to return up to 19.3mpg combined.
