Yes, it's the same twin-turbo V8 as the standard-issue DBX. However, it has been dialled up to 11 to produce a whopping 697bhp and 900Nm of torque – 155bhp and 200Nm more than before!

A few days ago, Aston Martin had officially teased a new version of the DBX. And it's here! Meet the new DBX707 (gets the suffix from its 707PS power output), the fastest and the most powerful iteration of Gaydon's premiere ultra-high-performance luxury SUV. While the DBX707 was rumoured to get a V12 heart, the engineers have decided to stick with the original V8. So, here's a look at all that's new or different on the DBX707.

In the DBX707, the 4.0-litre twin-turbocharged V8 pushes out an astonishing 697bhp and 900Nm of torque – this is 155bhp and 200Nm more than the standard DBX. It has been achieved by slapping on new ball-bearing turbochargers. Combine this with a bespoke engine calibration and a new nine-speed wet-clutch automatic gearbox, and what you get is an SUV that can crack 0 – 100km/h in just 3.3 seconds. To handle the extra torque output, the DBX707 also gets a new version of the electronic limited-slip rear differential (e-diff) – it features a revised (shorter) final drive ratio of 3.27.

There are some significant updates to the chassis as well. The DBX707 comes with Carbon Ceramic brakes as standard (420mm Front/390mm Rear). These have led to a 40.5kgs reduction in the car's unsprung weight, shrouded by 22-inch/optional 23-inch wheels.

The DBX707 also retains the standard car's air suspension system. However, it does get new damper valving and recalibrated dynamic spring volume switching to improve body control and steering response. The eARC (Electronic Active Roll Control) system has also been optimised for enhanced agility and dynamic balance.

There's also a new 'Race Start' option available in the GT Sport and Sport+ drive modes, to maximise off-the-line acceleration. Speaking of drive modes, the DBX707 also houses a revised lower console with dedicated drive mode selection and function switches. A highlight among these is the new 'active exhaust' switch, which opens the valves of the all-new quad-tailpipe sports exhaust system without needing to be in the Sport drive mode.

Visually, the DBX707 differentiates itself with a refreshed front-end look, courtesy of a larger satin chrome front grille (with double vanes and six horizontal bars that are split), new-design LED DRLs, redesigned air intakes, new brake cooling ducts and new louvred bonnet blades. Likewise, the refreshed rear end showcases a reprofiled bumper, the new quad-tailpipe exhaust tips, a significantly enlarged twin rear diffuser, a new lip spoiler and a roof wing.

The production of the DBX707 is due to commence in Q1 of 2022, with the first deliveries scheduled to begin during early Q2 2022.
