INFINITI QX-80 R-Spec Concept | Bob Moore INFINITI

INFINITI turned plenty of heads at the 2025 SEMA Show in Las Vegas with the INFINITI QX-80 R-Spec, a one-off take on its flagship SUV. Built around an engine from the Nissan GT-R, the luxury concept SUV shows what INFINITI’s designers and engineers can do when they set aside their usual limits. INFINITI hasn’t announced plans to build it, but the INFINITI concept vehicle gives us a fun look at what the brand can do with the QX80. In our guide below, we’ll preview the powertrain, design, and hardware behind INFINITI’s latest concept vehicle. If you’d rather drive a QX80 home today, browse our new inventory at Bob Moore INFINITI in Oklahoma City!

INFINITI QX-80 R-Spec Powertrain and Performance

Under the hood sits a modified version of the 3.8-liter twin-turbo V6 from the Nissan GT-R. INFINITI fitted custom turbochargers, intercoolers, and exhaust manifolds, along with an upgraded fuel system, and says the engine is tuned to reach up to 1,000 horsepower. That’s a target for the concept rather than an official rating at this time. Stopping power comes from GT-R carbon ceramic brakes that INFINITI adapted to fit the QX80. A custom coilover suspension replaces the production setup. As we learn more about the QX-80 R-Spec concept, we’ll keep you up to date!

Design and Styling of the QX80 R-Spec

Outside, a custom body kit makes the R-Spec wider and lower than the production QX80, with aerodynamic upgrades and styling inspired by the GT-R T-Spec Takumi Edition. Bronze 24-inch wheels measure 12 inches wide and wear 315-section tires. A Midnight Purple wrap finishes the look, another nod to that special-edition GT-R. Tiago Castro, VP of INFINITI Americas, described the R-Spec as a showcase of what INFINITI can do. For an INFINITI concept vehicle, it’s one of the boldest we’ve seen, and we’d love to see a few of its styling cues reach the showroom.

Will the QX80 R-Spec Reach Production?

INFINITI hasn’t shared plans to build or sell the R-Spec, so for now it’s a luxury concept SUV that lives on INFINITI’s concept vehicle page. If INFINITI changes course and builds a version of the R-Spec, we’ll share the details with our customers in Oklahoma City. You don’t need a concept to get serious power from the flagship, though, since INFINITI says the production QX80 has the highest standard horsepower in its class. Prefer to save on a flagship SUV? A CPO INFINITI is a great way to get into a QX80 for less, and our certified pre-owned inventory is a great place to start your search.
