Aston Martin DBX707 Breaks Cover; Does 0-100 kmph In 3.3 Seconds

Aston Martin has revealed the ultra high performance DBX707 and claims that it is the fastest and most powerful iteration of the SUV. Aston Martin clearly states that the DBX707 gets 'world-beating power and pace matched by exceptional precision, dynamic flair' and we don't doubt that one bit because what's under the hood is simply exceptional.



The 4-litre twin-turbocharged V8 has been used to its full potential. Led by Aston Martin's Head of Powertrain Engineering, Ralph Illenberger, the DBX707's engine now features ball bearing turbochargers and a bespoke engine calibration to liberate more power and torque. Also new to Aston Martin's flagship high performance SUV is a 9-speed 'wet clutch' automatic transmission. Capable of managing much increased torque loadings compared with a regular torque converter automatic, this high-performance transmission allows output of the 4.0-litre V8 to be lifted to an immense 697 bhp and 900Nm, which is an increase of 155 bhp and 200Nm over the DBX (V8).

The adoption of the new wet clutch transmission brings further benefits. Most noticeably much faster gear changes compared to the torque converter transmission. The feel of the shift is more immediate and direct, which gives the driver an increased sense of control and responsiveness, and a dramatic character change from the DBX (V8). Launch capability is also improved, which contributes towards the DBX707's 0-100 kmph time of 3.3 seconds.

Integral to the DBX707's suite of performance enhancements is the standard fitment of Carbon Ceramic Brakes. Measuring 420mm front and 390mm rear, these CCB discs are gripped by 6-piston calipers and result in a 40.5kg reduction in unsprung weight. Revisions to the braking system's hydraulic sizing and booster tune improve pedal feel and braking response for greater precision and driver confidence. Improved brake cooling has been achieved by taking air from both the main cooling intake and the underfloor, with high performance brake pads delivering excellent friction consistency across a wide temperature range.
