Nope, that ain’t a typo; it’s not supposed to be 007 or 077. It really is the DBX707, and those numbers represent something obvious—which we’ll get to in a minute anyway. But the DBX707 according to Aston Martin, is “the world’s most powerful luxury SUV”. The Model X Plaid owners might disagree on that, but I’m pretty sure Aston Martin is talking only about ICE-powered SUVs.
But anyway, let’s talk a little bit about the DBX707 which is not a limited edition product in any way. Since Aston Martin tasted a bit of sales success with the DBX, the folks probably decided to offer a more powerful version. Most of the visual changes that you see serve a purpose; the front openings are now larger to feed more air into the engine bay. At the rear, the roof spoiler has carbon fibre extensions, but the significant differences you’ll find on the bumper, where you’ll see quad circular tailpipes and a gigantic, multi-level diffuser. Notice that the extended diffuser sort of mimics the upswept tailgate.
On the side, you’ll notice gigantic wheels, which measure 22-inch as standard, but you can go for 23-inch ones; the wheels are wrapped with tyres that are said to offer improved steering response and better body control. Behind the wheels you’ll notice something just as gigantic: carbon ceramic brakes measuring 420 mm at the front and 390 mm at the rear; the discs are gripped by 6-piston calipers and offer a 40.5 kg (89.3 lbs) reduction in unsprung weight. As for suspension, well, the triple chamber air suspension has been carried over, but there are some model-specific tweaks to improve body control and steering response.
Inside, the electronic power steering system has been tweaked to improve the steering feel. And of course, there are Sport seats fitted as standard, which come with 16-way electric adjustment plus heating in front and rear as standard. However, Comfort seats are also available as a no-cost option. You’ll notice some changes on the lower centre console as well, which include dedicated buttons for suspension mode, ESP, manual gear selection mode, and active exhaust.
As for materials, the standard-fit seats come with a mix of leather and Alcantara, while there are few options as you might expect. Switchgear comes with a dark chrome finish as standard, while bright chrome and carbon fibre can be found in the options list. Piano Black veneer is standard, while carbon fibre or bronze metal mesh veneer finishes can be found in the options list. And of course, Q by Aston Martin division will be on standby for those who wish to spend more.
Moving on to the juicy bits of the story then, the DBX707 still packs AMG-sourced 4.0L V8 biturbo unit, but the stock turbos are replaced with larger ball bearing turbos, and when combined with new software, the results are 520 kW (707 metric hp) and 900 Nm (664 lb-ft) of torque; up by 115 kW (156 metric hp) and 200 Nm (147 lb-ft). The engine is paired with a 9-speed wet clutch automatic gearbox. For those interested to know, the official 0-100 km/h (62 mph) sprint time is 3.3 seconds and the top speed is 310 km/h (193 mph).
Another important highlight of the DBX707 is a new version of the electronic limited slip rear differential (e-diff). Strengthened to handle the full 900 Nm of torque, it features a revised (shorter) final drive ratio of 3.27 compared with 3.07 in the regular DBX V8.
Prices are yet to be announced but Aston Martin aims to commence deliveries by early Q2 2022.
