We didn’t know we needed a 1000-horsepower Infiniti QX80 until Nissan actually built one. The QX80 R Spec is a bold experiment that merges the luxury of Infiniti with the raw performance DNA of the legendary Nissan GTR. Built for the upcoming 2025 SEMA Show in Las Vegas, this one-off creation pushes the limits of what a full-size SUV can be.
At its core sits the renowned VR38DETT twin-turbo V6 engine, the same powerhouse that earned the GTR its Godzilla nickname. This particular motor was hand-built by Tsunemi Ooyama, one of Nissan’s elite Takumi craftsmen, and tuned to deliver an astonishing 1000 horsepower. The engine is paired to a seven-speed automatic transmission through a custom CNC-machined adapter, ensuring that the monstrous power is harnessed with precision.
To handle that kind of output, Infiniti engineered a fully reworked chassis. The QX80 R Spec rides on massive 24x12-inch bronze wheels wrapped in Yokohama 315/35R24 tires, providing immense grip and presence. Underneath, a set of MCS three-way adjustable coilovers with Eibach springs bring the SUV closer to the ground, while custom steering knuckles and a relocated steering rack improve handling and reduce bump steer.
Visually, the R Spec is as aggressive as its performance suggests. The widebody kit, inspired by the GTR T Spec Takumi edition, includes an ARP front splitter, sculpted bumpers, side sills, and a huge rear wing that juts out from the roofline. The Midnight Purple wrap pays tribute to the legendary R34 and R35 GTRs, while a custom rear diffuser and R35-inspired exhaust system complete the look.
