INFINITI turns its flagship luxury SUV into an unexpectedly raw performance machine with the QX80 R-Spec build, making its public debut at the 2025 SEMA Show. It has unprecedented performance from a version of the legendary Nissan GT-R's twin-turbo engine tuned to be capable of 1,000 horsepower.

QX80 R-Spec unleashes INFINITI's luxury flagship and makes an adrenaline-pumping statement about how QX80 can excite and empower clients. Following the introduction of the 650-plus-horsepower QX80 Track Spec concept at Monterey Car Week, R-Spec is a far more extreme, no-holds barred study of powerful yet luxurious SUV variants.

The INFINITI QX80 R-Spec build features a GT-R sourced 3.8-liter twin-turbo V6 that has received extensive modifications to be capable of 1,000 horsepower, with custom turbochargers, intercoolers, exhaust manifolds and an upgraded fuel system. Selecting a GT-R engine as a donor for this build was a direct nod to the lineage of the standard twin-turbo V6 in QX80, which is directly related to and incorporates numerous engineering innovations from GT-R.

"QX80 R-Spec is extreme, aggressive and a showcase of what INFINITI can do when our engineering and design teams take off all the guardrails," said Tiago Castro, vice president, INFINITI Americas. "With the QX80 R-Spec build, we challenged ourselves to explore an even more extreme direction for QX80 as we look to a future with high-performance variants that offer a broader breadth of adrenaline-pumping capabilities for our clients. We gave our team the freedom to be creative and dream of the unexpected as we redefine the future of luxury in a way that combines visceral performance with incomparable refinement."

QX80 R-Spec harnesses this additional horsepower with Nissan GT-R carbon ceramic brakes featuring bespoke modifications to match them with QX80. A custom coilover suspension optimizes handling. R-Spec wears bronze 24-inch wheels designed to resemble those from the GT-R, with a 12-inch width accommodating 315 section-width tires for exceptional grip levels.

Matching its upgraded capabilities, QX80 R-Spec wears a custom body kit that is wider, lower and aerodynamically enhanced. All of its visual enhancements are directly inspired by the GT-R T-Spec Takumi Edition, starting with an incredible, color-shifting wrap that pays homage to the Midnight Purple colors made famous on the R34 and R35 GT-R generations. The R-Spec also has restyled exhaust finishers, diffusers, fog lights, badges and other design cues similarly drawn from the T-Spec Takumi Edition, making the connection to GT-R even clearer. This aggressive new appearance exaggerates the already powerful design of the INFINITI QX80 and clearly connotes its exhilarating level of performance.
