DBX707 S : suspension retravaillée, pneus Trofeo R et freins carbone-céramique de série, plus un habitacle S affûté par Q. Notre guide clair et précis.
The DBX707 S arrives in 2025 with a simple promise: keep the punch of the 707 PS twin-turbo V8 while hardening the fundamentals. This guide highlights three structural engineering choices that set the S version apart from the standard DBX707: the suspension and its settings, the tyre/braking duo, and a sharpened cabin — with, in the background, what Q by Aston Martin actually brings. No lyricism, just sourced facts and a touch of perspective.
Suspension and settings: what the S changes versus the standard 707
The S logic at Aston Martin does not upend the powertrain — it sharpens the chassis. True to this tradition, the 2025 iteration focuses on suspension improvements and specific settings, made official for the DBX707 S. According to information from media.astonmartin.com, the S stands out through targeted adjustments rather than a full overhaul: the aim is to increase precision without sacrificing the versatility that made the DBX a success.
In practice, the mechanical fundamentals remain identical: a 4.0-litre twin-turbo V8 with 707 PS (520 kW) and 900 Nm, paired with a 9-speed automatic gearbox, as confirmed by the official DBX707 page on Aston Martin’s site and Wikipedia’s technical summary. The S does not chase a power hike; it aims for a measured sidestep, consistent with the “S” nomenclature historically tied to sportier setups (DB11 AMR, Vantage S), without major engine changes.
This refocus on settings is also a strategic message: offer a keener variant for experienced drivers while preserving the everyday ease-of-use that defines the DBX. In this light, the gap to the standard 707 lies in nuances — damping responses, body motion control, and mode calibration — rather than raw figures.
Tyres and braking: Pirelli P Zero Trofeo R and carbon-ceramic as standard
The second pillar is unambiguous: Pirelli P Zero Trofeo R fitted as standard on the DBX707 S, as announced by media.astonmartin.com. An uncompromising choice, the Trofeo R is designed to maximise hot grip and consistency under sustained lateral load. On a SUV with over 700 PS, this translates to a clearer read of available grip and rapid warm-up — in other words, a sports car feel, not grand touring.
Complementing this, carbon-ceramic braking becomes standard on the S version. Again, the priority is consistency and resistance to fade during intensive use. The benefit is twofold: a more stable pedal under heavy loads and increased thermal endurance — key factors when regularly exploiting the DBX’s full performance. Together they create a coherent triangle: tyres focused on traction and precision, high-endurance discs, and a tightened suspension calibration.
This “tyres + brakes” pack says a lot about the intention: the S is not a DNA shift, it’s a firm nudge of the cursor towards committed driving. For the record, the baseline remains explosive — 0 to 100 km/h in 3.3 s according to Aston Martin — but the way you get there evolves: more exploitable grip and a more unflappable brake feel, hence greater confidence in spirited driving.
The S cabin: Sport Plus personalisation and what Q by Aston Martin really adds
The third choice is subtler: the S cabin is distinguished by specific presentation and options. “Sport Plus” personalisation underscores the dynamic brief: a bolder ambience, upholstery and trims aligned with the chassis mission. This isn’t a radical ergonomic leap, but an aesthetic and tactile coherence that accompanies the technical changes.
The role of Q by Aston Martin deserves precise framing. Q adds tangible value — exclusive materials, textures, colours — but no mechanical gains. It’s the tailor’s touch: a broader palette that lets the visual signature match the S’s dynamic intent. In practice, you get an even more distinctive cockpit without changing how the DBX707 S accelerates, turns or brakes.
This separation of domains — technical on one side, bespoke on the other — is true to the brand’s tradition. For customers seeking a clear takeaway, remember this: the hardware that changes the drive sits with suspension, tyres and brakes; the aesthetic software lives with Q. To place the S within the family, our comparison feature on the 5 innovations of the DBX S 2026 versus the DBX707 offers a complementary angle — while here the focus remains on 2025’s three structural decisions.

Conclusion: why the DBX707 S refines the DBX707 proposition
In short, the DBX707 S stands out through three decisive engineering choices: a retuned suspension for greater precision, Pirelli P Zero Trofeo R to maximise grip, and carbon-ceramic brakes as standard to secure repeatable performance. The engine remains the 707 PS, 900 Nm twin-turbo V8, in keeping with Aston Martin’s “S” ethos. The result: the DBX707 S doesn’t add decibels — it refines the signal.
For demanding drivers, the appeal is clear: more consistency and clarity at higher pace while preserving the daily usability that underpins the DBX. The official sources — media.astonmartin.com and the DBX707 page — confirm the brief: the 2025 S version doesn’t reinvent the spec sheet; it makes it more exploitable. A measured, effective, thoroughly British set-up.
