Aston Martin DBX 707: the most powerful SUV

The electric transition? Aston Martin thinks about it. But before really getting down to it, the firm is still having fun with thermals. The proof with this overpowered variant of the DBX, presented as the most muscular SUV in the world.

The technical basis remains the 4.0-liter biturbo V8 from Mercedes-AMG. But Aston modified it to incorporate ball-bearing turbochargers, then completely recalibrated “to maximize power and torque”. There are thus 707 hp, 157 hp more than the classic DBX V8. We note all the same that this power had already been achieved by the Jeep Grand Cherokee Trackhawk, which is no longer in the catalog.

The V8 is here associated with a new 9-speed automatic transmission with wet clutch. This can take more torque than a traditional torque converter auto box. The maximum torque thus increases from 700 to 900 Nm. The vehicle goes from 0 to 100 km/h in 3.3 seconds.

The DBX 707 is fitted with carbon ceramic brakes as standard, with 420 mm discs at the front and 390 mm at the rear and six-piston calipers. With a modified underbody, more air is directed to these brakes to cool them better. This DBX of course has all-wheel drive, with the possibility of sending 100% of the torque to the rear. The electronic limited-slip rear differential has been revised. The same goes for the suspension and steering, always with the aim of combining performance with agility.

This DBX benefits from a more muscular look, with for example at the front an enlarged grille, placed above a large air intake which goes up on the sides. At the rear, we notice the four tailpipes and a new diffuser. As standard, this DBX is mounted on 22-inch rims! On board, among the developments, the base of the console changes to incorporate new buttons for selecting driving modes and to avoid getting lost in the touch screen menus.

The first deliveries are scheduled for the end of the first half of 2022.
