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.
