What happens when you put the world’s most powerful SUV on a circuit known for its terrifying turns? It’s not the Aston Martin DBX707 that bursts first.
The most powerful in the world, yes. We know that this title used to go to the Jeep Grand Cherokee Trackhawk with 717 horsepower, but it no longer exists in the American manufacturer’s catalog. The new 707 Aston Martin DBX version beats all its current competitors in terms of net performance, from the Lamborghini Urus (650 hp) through the Porsche Cayenne Turbo S E-Hybrid (680 hp) to the Bentley. Bentayga Speed (635 hp). Powered by turbochargers different from the normal 550 hp DBX, this new version’s V8 develops, as its name suggests, 707 hp for 900 Nm of torque. Very impressive values for a block of four liters of displacement (AMG origin), equivalent to those of the large 5.2-liter twin-turbo V12 from Aston Martin, located under the hood of the DBS Superlegger (725 hp and 900 Nm). You wonder why the Gaydon builder bothered to make his own twelve-cylinder!
Right normal DBX (550 hp). Left DBX707
Good to know: anticipate buying and reselling.
Thanks to the Turbo car rating of your Aston Martin DBX, an alternative to the Argus rating, it is possible to know the value of your vehicle at the next sale or counter-account.
As usual with the extreme version of this type of model, the external presentation develops, although the differences really jump into the eyes only if you place the DBX707 next to the normal DBX: the radiator grille becomes gigantic, the rear diffuser grows by equipping larger exhausts and hiding shields more generous gills. The cabin doesn’t change much either. We find a dashboard with a somewhat interesting design (with a non-touch display with old-fashioned ergonomics) and an interior with a magnificent finish (in Aston Martin we can make beautiful leather). There is also this large suitcase and these rear seats, which will affect the habitability and large luxury SUVs. It feels almost like a Range Rover …
The big difference from a normal DBX is at the bottom of the center console: it’s a wheel that allows you to select piloting modes.
It’s starting badly
This presentation takes place on the German Blister Berg circuit, which is a track with magnificent relief, often nicknamed the “Little Nordschleife”, full of blind turns and other very technical turns that require courage and a lot of confidence. In short, ideal for testing a new car with very high sporting demands. For this occasion, we will have to follow the lead car, a DBS Superlegger driven by an instructor who is none other than Sebastian Vettel’s brother. Which gives us confidence to be able to really identify the capabilities of the car when we start our DBX707, then place the selector (at the bottom of the center console) in Sport + mode. The V8 rattles when started and remains present in the cab when this Sport + mode is activated. But the experience turns into a catastrophe: we find ourselves in a group of five DBX707s, and the other cars are mainly foreign journalists, whose slowness obliges the leading car to print the senatorial train. Being able to return to Comfort mode and see that this big SUV doesn’t sacrifice anything at this level. The automatic transmission, as well as the damping, then show excellent softness and the V8 can no longer be heard in the cab, while we calmly follow the other cars.
Aston Martin DBX707, in the service of omnipotence – TURBO test dated 17.04.2022
It’s not visible in the picture, but we’re going really slow right now
A colleague from the French sports press is even more angry than we are. How to seriously measure the dynamic efficiency of such a car without actually being able to attack the circuit? At the end of the ride, we ask the people from the organization to return to driving without other journalists, only with Fabian Vettel and his noble DBS Superlegger. Only the three of us are going again. Sport + mode activated, ESP disconnected, we’ll really see what this heavy beast weighs 2,245 kg empty in the stomach. This time we flew all the news about the nine-speed automatic transmission, extrapolated from that Mercedes-AMG E63S (as well as the rest of the transmission deeply redesigned by Aston Martin). In manual mode, it shows a satisfactory response. For this type of large SUV, where high torque and towing capacity prevent manufacturers from installing dual-clutch transmissions as good as real sports cars, the DBX707 cabinet seems at least as effective as the ZF Porsche Cayenne or Audi. RS Q8. The V8 booms in the cab without going as far into sonic exuberance as the old Range Rover Sport SVR. As for traction (from 0 to 100 km / h reported in 3.3 seconds), it seems at the promised level, which will undoubtedly allow you to easily follow the BMW M5 or Audi RS 6 in the left lane of German motorways (note that the DBX707 also claims the title of the fastest SUV in the world with a maximum speed of 310 km / h).
Blister Berg, an extremely technical and hilly circuit nicknamed the “Little Nordschleife”
A colleague driving in front of me, whom I have known for fifteen years, literally sticks to Vett’s DBS bumper with his SUV and forces him to increase his pace even more. And it is this moment that reveals the differences between a good pilot – this cumbersome colleague who has the same first name as Patrick Bruel and the same name as José Garcia – and me. While he still seems to be slowed down by a nice sports car in front of him, I’m starting to lose rhythm. DBX707 has nothing to do with it : despite the slightly soft pedaling of the large carbon-ceramic brake (420mm discs at the front, as in the Bugatti Chiron), the machine stops the wheel behind the wheel without incident. Flexible on its supports, it is constantly rolling, which does not prevent it from showing perfect stability on this very steep German water slide. Despite the mass and problematic center of gravity of this luxurious pachyderm, the front axle cuts decently, and when understeer finally occurs, Aston is not splitting up. In response to the lifting of the foot, the great Englishman also uses his transmission, which can send up to 100% of torque to the rear axle. It allows you to glide from corners, but only to a certain extent on our pre-production test models. In this regard, the people of Aston Martin assured us on the spot that the latest copy will allow you to take turns at the door while smoking a lot. If you can.
That’s it, the others spun in front …
Because right now, I’m out of my comfort zone and I’m trying to stay in touch with the other two cars. I miss the ropes and downshifts, I’m braking too soon, and my brain has consistently refused to let go of its throttle despite those dizzying inequalities in blind turns with a gigantic overhang. In any case, the SUV exhibits imperial traction despite numerous load breakdowns on the circuit. Fortunately, because here the slightest mistake of the pilot could have serious consequences for more advanced cars. After a few turns, the DBS and other DBX707 are out of reach. My wet back sticks to the skin of the seat, and when I finally attack the cooling tower, the smell of sweat begins to seep into the cabin. Humiliated again by this colleague, who keeps damaging my self-confidence, at least I have the satisfaction of being able to experience the price of the DBX707 on the circuit. And even despite the burlesque side of finding yourself with such a heavy SUV on the circuit, discover the good feelings of driving on one of the most difficult circuits on the planet. Is he doing better than his competitors? In my memory, the Porsche Cayenne, tighter and stronger with less light driving, seemed less amusing and nothing more efficient. Between this DBX707, the Lamborghini Urus and the Cayenne GT is an obvious match. With a price of EUR 240,504 per piece, it also costs a little more than the other, but given the shape of the machine and its degree of comfort, there is really everything to make the DBX707 a new ATM from Aston Martin. That’s good, the manufacturer really needs it now. And I’m going to take a shower after getting that scary Blister Berg.
