Aston Martin DBX707

 Aston Martin DBX707:

If the first official photos of the Aston Martin DBX707, a tad obscure, maintain a certain suspense with regard to some of its aesthetic details, its power is at least no mystery. As in the case of a certain cheese brand, it is written on it. From the same V8 4.0 biturbo of AMG origin that equips the “normal” DBX, its high-performance version, particularly recognizable by its extended grille, extracts an additional 157 hp for a total of 707. The maximum torque is not in remains since it jumps 200 Nm to reach 900. While waiting for Ferrari to draw its SUV (who said as late as possible?), Aston's thus displays an unequaled cavalry in the category, at least among its European rivals. Admittedly, without V12, but without battery or electric machine either! Even Lamborghini's Urus has to bow for now. The excess of power is obviously not without consequences on the rest of the mechanics. The automatic transmission is the first to bear the brunt of this questionable one-upmanship. It must indeed give way to another transmission, still with 9 gears, but which reminds us of the Speedshift MCT from Mercedes-AMG since it is equipped with a multi-disc clutch instead of the traditional converter. Generally capable of further limiting its slippage, this solution is promised to be more robust and above all more favorable to driving sensations and performance. Its Launch Control would allow the DBX707, the first units of which should be delivered before the summer, to take off from 0 to 100 km/h in 3”3. We only ask to try to see. The shortening of the final gear ratio pleads in any case in favor of this chrono canon. But there would be even more hair-raising, if this integral, perched on its 22” rims (23” as an option) and weighing well over two tonnes, shears the asphalt as well as it claims afterwards. various changes. The piloted rear differential adopts a specific management, just like the steering assistance, in order to gain consistency around the midpoint.

This paraphernalia is completed here as standard with a braking system with carbon-ceramic discs whose diameter extends over 420 mm at the front. It certainly does not take less to stop with dignity such a behemoth which, in passing, benefits from a reduction of approximately 40 kg of its unsprung masses.
