Infiniti Teases High-Performance QX80 R-Spec with Nissan GT-R Engine, Set to Debut at SEMA 2025
Infiniti is teasing its “wildest concept yet” – a high-performance QX80 R-spec – set to debut at SEMA 2025, hinting that the legacy of the legendary Nissan GT-R is far from over, just taking a different shape. This radical concept is expected to be powered by the GT-R’s iconic 3.8-liter VR38DETT V6 engine, promising to “redefin[e] luxury performance from the ground up.” While details are scarce, the QX80 R-spec will likely exceed 500 horsepower, easily eclipsing the stock QX80’s 450 hp. The teaser reveals a vivid Midnight Purple finish, an R-spec badge reminiscent of the GT-R T-spec, and twin titanium exhaust outlets seemingly borrowed from the supercar. The unveiling is scheduled for SEMA on October 27, though production plans for this specific concept are not guaranteed.
The GT-R Legacy Reimagined
Infiniti is tapping into the iconic legacy of the Nissan GT-R to create an unexpected high-performance luxury SUV.
- GT-R Engine: The upcoming QX80 R-spec concept is expected to be powered by the 3.8-liter VR38DETT V6 engine that famously powered the R35 GT-R.
- “Luxury Gets a New Heartbeat”: A short press release from Infiniti confirms this direction, stating the brand’s flagship SUV is “redefining luxury performance from the ground up.”
- SEMA Debut: This “wildest concept yet” is set to debut at SEMA 2025 on October 27.
- Performance Expectations: The QX80 R-spec is expected to deliver more than 500 horsepower, easily surpassing the stock QX80’s 450-hp VR35 engine, with the outgoing GT-R’s VR38 offering a wide range of potential tunes (565 to 710 hp).
Design Cues and Unanswered Questions
The teaser provides intriguing hints about the QX80 R-spec’s visual and mechanical details.
- Midnight Purple Finish: The R-spec appears finished in a “vivid take on the GT-R’s Midnight Purple” paint.
- GT-R Inspired Details: It sports an R-spec badge reminiscent of the T-spec GT-R, and features “twin titanium exhaust outlets [that] sit within a bumper design that looks almost borrowed from the supercar.”

- Expected Upgrades: Like these previous projects, the new R-spec build might feature improved cooling, bigger injectors, and Brembo brakes.
