Limited‑Run 2026 Aston Martin DBX S — 717 hp

Aston Martin’s 2026 DBX S is a limited‑run, top‑of‑the‑line DBX variant (3,000 units worldwide, 1,000 for the U.S.) positioned above the DBX707. It raises the Mercedes‑AMG 4.0‑liter twin‑turbo V8 to 717 hp and 664 lb‑ft using larger turbochargers borrowed from the Valhalla hypercar, yielding modest stopwatch gains (similar 0–60 times but quicker at higher speeds). Significant lightweighting options — including an optional carbon‑fiber roof and forged 23‑inch magnesium wheels — can cut roughly 100 lb to improve agility, while revised drivetrain and chassis hardware (a 4% quicker steering rack, recalibrated air springs, adaptive dampers, electronic anti‑roll control and retuned nine‑speed transmission) sharpen responses. Visually it gains a new grille, reshaped bumpers, vertically stacked quad exhausts and optional carbon diffusers, and equipment highlights include massive carbon‑ceramic brakes and the new Apple CarPlay Ultra across Aston’s 2025 fleet. Early first drives praise the DBX S’s unexpectedly light‑footed handling and drama, suggesting it may be Aston Martin’s most engaging high‑performance SUV despite only modest stopwatch improvements over the 707.
