Infiniti has turned heads at the 2025 SEMA Show with the debut of the QX80 R-Spec, a 1,000-horsepower re-imagining of its flagship SUV. Under the hood lies a modified version of the GT-R’s 3.8-litre twin-turbo V6, the VR38DETT—tuned far beyond factory limits and paired with a reinforced drivetrain, carbon-ceramic brakes, and custom coil-overs to handle the immense power.

Finished in Midnight Purple and fitted with 24-inch bronze wheels, the R-Spec pays tribute to the GT-R’s legendary heritage while redefining Infiniti’s image with a performance-driven edge. Inside, the cabin blends the QX80’s luxury DNA with motorsport-inspired accents, illustrating the balance between comfort and capability.

While Infiniti describes the R-Spec as a concept, the project hints at a potential shift toward a dedicated performance line—one that could finally see Infiniti compete with the likes of AMG and M Division.
