It’s been long enough for us to accept the reality that luxury performance SUVs are a thriving bunch. Aston Martin was a bit late to the party with the DBX that premiered towards the end of 2019. The British moniker has taken the covers off the beefed-up version: the DBX707.

Aston seems to have taken a leaf out of Ferrari’s playbook for uninspiring model names with this one as the digits stand for the power output of the souped-up SUV: 707PS. It uses the same AMG-sourced 4.0-litre twin-turbo V8, but it’s been thoroughly tinkered with by Aston Martin’s Powertrain Engineering wizards and features ball-bearing turbochargers and bespoke engine calibration. The result is an extra 155bhp and 200Nm over the regular DBX for a revised output of 697bhp and 900Nm.

A jump in performance that big requires upgrades to other aspects of the powertrain as well. That leads us to the new 9-speed ‘wet clutch’ transmission for distributing power to all four wheels, allowing the DBX707 to launch from 0 to 100kph in just 3.3 seconds. Aston Martin engineers also had to strengthen the electronically limited rear slip differential to handle the extra torque. After all, it can still send up to 100% of torque to the rear axle on demand. The recalibrated e-diff also ensures the DBX707 has improved cornering and offers a more dynamic driving experience.

Speaking of dynamism, the company has also worked to make the most powerful luxury SUV, fun to drive. That includes stiffening up the suspension, adjusting the 48v body control system, and reconfiguring the air suspension. The electronic power steering has been adjusted as well for a more engaging driving feel.

With bigger performance comes bigger brakes, especially in something the size of the DBX. So, the 707 is fitted with carbon-ceramic brakes with 6-piston callipers, 420mm front and 390mm rear. They’re lighter too, resulting in a loss of 40.5kg from the car’s unsprung weight. It also gets the choice of new, bespoke 23-inch wheels but gets 22-inchers as standard.

There are a host of visual changes to the DBX707, giving it a brutish appeal to match the new performance numbers. The most notable change at the front is a much larger grille, bursting out of the distinctive Aston shape. Like BMW, it needs the bigger opening for more air to feed that monstrous bi-turbo V8. Its width is pronounced further by the horizontal bars. There are other new vents and intakes on the front fascia to help channel air as required. It also gets a new look for the DRL light signatures flanking the enlarged grille and an aggressive front splitter.

Further along the DBX707, you’ll see other visual changes such as the dark chrome surrounds, vents behind the front wheel arches and sportier side sills that add to the dynamic stance of the luxury SUV.

But the most dramatic visual change for the DBX is at the back. It gets a new twin-plane rear diffuser that seems unbefitting of an SUV. The design mimics the shape of the LED taillights integrated into the sculpted boot-lid spoiler. Just above the angry rear diffuser, we see the scary quad-exit exhaust setup. At the top, you’ll find a new lip spoiler in addition to the pre-existing roof wing for increased high-speed stability and rear downforce.

The sporty updates carry forward to the luxurious interior as well. It is finished in a mix of leather and Alcantara with the sporty seats as standard. Aston Martin has transferred its dark chrome aesthetic from the exterior to the interior as well by applying it to the switchgear. Buyers will get a wide variety of personalisation options including carbon fibre touches around the cabin. The coolest aspect of the central console, in my opinion, is the rotary dial flanked by four buttons on each side. Not the most unique idea for a V8 sportscar (coughAMG), but looks cool in this finish seen in the DBX707.

Given that buyers of luxury performance SUVs rarely go for the entry model, it seems like the DBX707 could become the most popular variant since it’s not a limited production. On that note, let’s quickly address Aston’s claim of making the most powerful luxury SUV. At 697bhp, it trumps the Lamborghini Urus by 56bhp, the Bentley Bentayga Speed by 71bhp, and 94bhp more than the Mercedes AMG GLS63. Yes, the Jeep Grand Cherokee Trackhawk and Tesla Model X Plaid have more power to put down, but they don’t qualify as “luxury” SUVs.
