Aston Martin DBX range revised: brawny 707 engine now standard and new infotainment slides in

► Aston Martin DBX range revised for 2024
► DBX 707 spec becomes only model available
► New touchscreen tech from DB12 slides in

The Aston Martin DBX range is being overhauled for 2024 – and the key adjustments are the standardisation of the brawniest DBX 707 engine, becoming the single powerplant offered on the performance SUV, and the arrival of the latest touchscreen infotainment from the DB12 and other models.

Previously, the 707 was reserved as a top-level trim and at launch in 2022 Aston touted it as ‘the world’s most powerful luxury SUV.’ That claim was helped when Jeep’s Grand Cherokee Trackhawk and Dodge’s Durango SRT Hellcat – both more powerful than the 707 – went off sale in their home markets. Handy, that.

The new 2024 Aston Martin DBX 707 is named after its metric power output: 707hp, equivalent to a colossal 697bhp in imperial horses. The Mercedes-AMG developed 4.0-litre V8 has its torque mountain massaged to 664lb ft, which might explain the prodigious performance on offer.

Gaydon claims its high-performance SUV can sprint to 60mph in just 3.1 seconds and top speed stands at 193mph – both figures unchanged for 2024. It’s significantly faster than the original launch DBX, which made do with ‘only’ 543bhp/516lb ft.

All of that shove is sent to all four wheels by a nine-speed wet-clutch transmission, modified air suspension and a toughened electronic differential for the rear axle, where in extremis 100 per cent of the power can be sent to the back axle.

Carbon ceramic brakes are standard, too, with Aston saying they remove 40.5kg from the unsprung mass – handy for ride quality and handling. The DBX is made from bonded aluminium, like all Astons, to keep a lid on weight.

Sizeable 22-inch alloys are standard on DBX 707, but customers can upgrade to 23in rims should they wish (and many surely will).

Other than dropping the less powerful ‘regular’ V8 model, not much is changing with the engineering spec of the 2024 DBX range. Instead, most of the improvements are focused on the interior.

The latest family infotainment is installed and there’s a comprehensive interior makeover. The touchscreen tech is
