There is a new competitor in the world of ultra-high-performance SUVs. We clarify this as very high performance because the standard edition Aston Martin DBX with 542 horsepower is no slouch at all. But we’re not talking about the standard model – it’s the DBX707 and if you’re wondering where that number is coming from, just look under the hood.
That’s where you’ll find the familiar 4.0-liter V8 engine, but massaged to produce no less than 697 horsepower (707 metric horsepower, hence the 707) and 663 pound-feet (900 Newton-meters) of torque. To make this happen, Aston Martin installed a pair of new ball bearing turbochargers along with a new engine calibration to maximize the added boost. More air going in requires better piping to get it out, so the DBX707 gets a completely new quad-exit active exhaust system that flows better while also providing passengers with great V8 sound when desired.
Having power means nothing if you can’t use it, and as for Aston Martin, a lot of work has gone into the DBX707’s drivetrain. For starters, there’s a new nine-speed wet clutch gearbox with automatic and manual modes that allow for faster gearshifts. The latest version of the rear e-diff is more powerful, and has a shorter 3:27 final drive for better acceleration. The all-wheel-drive system is still an automatic affair, sending power forward or rear wherever it’s needed most, but the e-diff calibration helps in cornering.
The chassis has additional reinforcement, and the air suspension gets revised dampers and springs to reduce body roll. That works in tandem with updates to the Electronic Active Roll Control (eARC) system to further suppress non-compliant DBX movements. An updated electronic steering system adds weight to the steering wheel, and when it’s time to stop, carbon-ceramic disc brakes measuring 16.5 inches at the front and 15.4 inches at the rear are clamped by six-piston calipers. They sit behind the standard edition’s 22-inch wheels, with an optional 23-inch.
Speaking to reporters, Aston Martin CEO Tobias Moers reckons the DBX707 is the only performance SUV that can pull off a proper high-speed launch. With the “Race Start” mode pushing the SUV forward from 4,000 RPM, 60 mph arrives in 3.1 seconds. Keep the throttle pinned and the DBX707 will hit 193 mph. That’s enough to outperform all of its luxury competitors, but the SUV still retains all its luxury touches. Sports seats with dark chrome trim are standard, but comfortable seats in a lighter traditional chrome or carbon fiber finish are optional. The bottom console is specific to the DBX707, as it features manual controls for various driving and exhaust modes.

On the outside, this muscular SUV gets an aggressive front fascia with a large grille, new air intakes, redesigned daytime running lights and a flat front splitter. The upgraded rear fascia makes room for a quad finisher exhaust at the bottom, not to mention a larger diffuser. It’s impossible to miss the aloft lip spoiler, and you’ll find plenty of dark chrome and satin trim on the outside for a monochromatic effect. And as a final reminder that the DBX707 is still a luxury machine, Aston Martin added soft-close doors.
As you’d expect, power and prestige at this level doesn’t come without a cost. Price for DBX707 Get started at $232,000 and that doesn’t include destination fees. Aston Martin said production began in the first quarter of 2022, with initial customer deliveries following in the second quarter.
