Why the DBX707 and DBX S Are the Most Powerful Way to Carry a Family in an Aston Martin

Why the DBX707 and DBX S Are the Most Powerful Way to Carry a Family in an Aston Martin

For Aston Martin owners who need more than two seats, the choice has always come down to one model: the DBX. Today, the DBX comes in two distinct forms — the DBX707 and the new DBX S — and both prove that family practicality and supercar-grade performance can live in the same vehicle. Each is powered by the same 4.0-litre twin-turbo V8, each seats up to five, and each delivers performance figures that would have been unthinkable from an SUV a decade ago.

This guide walks through both models trim-by-trim, compares them side-by-side, and helps Montreal buyers decide which is the right Aston Martin SUV for their family.

DBX707: The Original Supercar of SUVs

Launched in 2022 and comprehensively updated in 2024, the DBX707 is Aston Martin's single SUV powertrain — the model that established the brand's foothold in the ultra-luxury performance SUV segment. The "707" in the name refers to its 707 PS power figure, which translates to 697 hp in North American terms.

Powertrain and Performance

  • 4.0-litre Twin-Turbo V8
  • 697 hp and 664 lb-ft of torque
  • 9-speed wet-clutch automatic gearbox
  • All-wheel drive, capable of sending up to 100% of torque to the rear axle on demand
  • 0 to 100 km/h in 3.1 seconds
  • Top speed of 310 km/h

Standard Equipment Highlights

  • 22-inch wheels as standard (23-inch cast or forged available)
  • 420 mm front and 390 mm rear carbon-ceramic brakes
  • Aston Martin's next-generation in-house infotainment with 12.3-inch driver display and 10.25-inch central touchscreen
  • 800W 14-speaker Aston Martin Premium Audio system as standard
  • Optional 23-speaker, 1,600W Bowers & Wilkins surround-sound system

The DBX707 is engineered for owners who want the daily usability of a five-seat luxury SUV without giving up sports car performance. Three interior trim specifications are offered — Inspire Comfort, Inspire Sport, and Accelerate — each with its own signature embroidery and material treatments.

DBX S: The New Flagship SUV

The DBX S, announced in April 2025 with deliveries beginning in Q4 2025, sits above the DBX707 as the new SUV flagship. It uses the same fundamental architecture but adds 20 PS through turbo technology transferred from the forthcoming Valhalla supercar, plus a focused weight-reduction programme.

Powertrain and Performance

  • Same 4.0-litre Twin-Turbo V8, upgraded with Valhalla-derived turbo internals
  • 717 hp and 664 lb-ft of torque
  • Same 9-speed wet-clutch gearbox, with revised shift mapping in Sport and Sport+ modes
  • 0 to 100 km/h in 3.3 seconds
  • Top speed of 310 km/h
  • Up to 47 kg of weight savings over the DBX707 with full lightweight options

What's New on DBX S

  • Optional carbon-fibre roof — at nearly three square metres, the largest single carbon element ever fitted to an Aston Martin, saving 18 kg from the highest point of the car
  • Optional 23-inch magnesium wheels — the first time magnesium wheels have been offered on any vehicle in the ultra-luxury SUV segment, saving 19 kg of unsprung mass
  • Optional polycarbonate honeycomb grille with over 25,000 individual facets
  • New stacked quad-exhaust design, available in gloss or matte finish
  • Faster steering ratio (4% quicker) and tighter 12.0-metre turning circle
  • Signature herringbone seat design, "S" badging, and Alcantara-and-leather interior

The DBX S is the choice for buyers who want the most focused, most powerful, and most exclusive Aston Martin SUV available.

A note on the 0–100 km/h figures: the DBX707 launches marginally quicker off the line, but the DBX S's revised gearing and extended rev range deliver a faster 0 to 200 km/h time by 0.3 seconds, and the lightweight options improve handling response in ways the stopwatch doesn't fully capture.

Family Practicality, Aston Martin Style

Both DBX models seat five comfortably, with generous rear-seat space and a cargo area sized for a family weekend. The cabin architecture is shared with the DB12 and Vantage — bonded aluminium structure, in-house infotainment, physical controls retained for the most-used functions like gear selection, drive mode, and climate. Apple CarPlay and Android Auto are standard wirelessly.

For Quebec families, both DBX models offer:

  • All-wheel drive with variable torque distribution, suitable for snow and slush
  • Available 23-speaker Bowers & Wilkins surround sound
  • Wireless smartphone integration and multiple USB-C connections
  • Extensive personalisation through Q by Aston Martin

The DBX S adds the option of a panoramic carbon-fibre roof, which gives back-seat passengers a uniquely Aston Martin view of the sky on long drives north of Montreal.

Which Aston Martin SUV Is Right for You?

The DBX707 remains the benchmark in its segment and is the right choice for buyers who want the complete Aston Martin SUV experience without committing to flagship-level personalisation. Its 697 hp, 3.1-second 0–100 km/h time, and 310 km/h top speed cover every realistic performance need.

The DBX S is for buyers who want the most powerful, most exclusive, and most visually assertive DBX. The Valhalla-derived turbo internals, optional carbon roof, magnesium wheels, and bespoke "S" interior treatments combine into a vehicle that stands clearly apart from the rest of the range.

Both can be specified extensively through Q by Aston Martin, so no two examples need ever be alike.
