The 4.0-litre V8 has now been tuned to supply 697 bhp and 900Nm, which is a rise of 155 bhp and 200Nm over the DBX (V8).
Aston Martin has revealed the extremely excessive efficiency DBX707 and claims that it’s the quickest and strongest iteration of the SUV. Aston Martin clearly states that the DBX707 will get ‘world-beating energy and tempo matched by distinctive precision, dynamic aptitude’ and we do not doubt that one bit as a result of what’s below the hood is solely distinctive.
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 options ball bearing turbochargers and a bespoke engine calibration to liberate extra energy and torque. Also new to Aston Martin’s flagship excessive efficiency SUV is a 9-speed ‘moist clutch’ automated transmission. Capable of managing a lot elevated torque loadings in contrast with an everyday torque converter automated, this high-performance transmission permits output of the 4.0-litre V8 to be lifted to an immense 697 bhp and 900Nm, which is a rise of 155 bhp and 200Nm over the DBX (V8).
The adoption of the brand new moist clutch transmission brings additional advantages. Most noticeably a lot quicker gear adjustments in comparison with the torque converter transmission. The really feel of the shift is extra quick and direct, which supplies the driving force an elevated sense of management and responsiveness, and a dramatic character change from the DBX (V8). Launch functionality can be improved, which contributes in direction of the DBX707’s 0-100 kmph time of three.3 seconds.
Integral to the DBX707’s suite of efficiency enhancements is the usual fitment of Carbon Ceramic Brakes. Measuring 420mm entrance and 390mm rear, these CCB discs are gripped by 6-piston calipers and lead to a 40.5kg discount in unsprung weight. Revisions to the braking system’s hydraulic sizing and booster tune enhance pedal really feel and braking response for higher precision and driver confidence. Improved brake cooling has been achieved by taking air from each the primary cooling consumption and the underfloor, with excessive efficiency brake pads delivering wonderful friction consistency throughout a large temperature vary.
Wheels and tires are 22-inch as customary (in a alternative of Sport and Ribbon designs), with an non-compulsory 23-inch alloy wheels supplied in a alternative of textured black or satin black with diamond turned highlights. The adoption of a 23-inch wheels additionally brings dynamic advantages, with the bigger diameter tire providing improved steering response, higher main physique management and improved lap occasions.
DBX707 additionally includes a new model of the digital restricted slip rear differential (e-diff). Strengthened to deal with the complete 900Nm of torque, it includes a revised (shorter) remaining drive ratio of three.27 in comparison with 3.07 for the DBX V8. This aids the DBX707’s sprinting skill by the decrease gears and enhances in-gear response, whereas retaining the effectivity and cruising refinement supplied by the 9-speed transmission.
Torque distribution front-to-rear stays totally automated, with the power to ship as much as 100% of the torque to the rear axle on demand. Careful calibration of the e-diff ensures the DBX707 has the cornering agility, sporting really feel and dynamic character of a real sports activities automotive. One that integrates chassis and powertrain know-how to search out the sweetest dealing with steadiness and search to take care of the optimum mixture of traction and agility always.
Key to the DBX707’s distinctive dealing with is its air suspension system. Retaining the fundamental structure and triple quantity air chambers of the DBX V8 – already considered the best-handling SUV available in the market – DBX707 includes a devoted chassis tune optimized to its uncompromising calls for and aims.
Starting with the suspension, DBX707 options new damper valving and recalibration of dynamic spring quantity switching to enhance physique management and steering response. The digital energy steering system has additionally been adjusted to enhance steering really feel, with higher effort build-up off heart to assist the driving force construct a clearer image of accelerating cornering masses and out there grip.

Aston Martin Chief Executive Officer, Tobias Moers, stated “Right from its first introduction the DBX has represented Aston Martin’s dynamic and design values ​​in a way that proves not all SUVs compromises have to conform to the same compromises. With the DBX707 we have pushed the boundaries in every area to create a car which sets new standards of performance and desirability. The fastest, most powerful, best handling and most engaging car of its kind, it propels Aston Martin to the pinnacle of SUV performance.”
