- The Subaru WRX NBR Challenge 2026 has been unveiled.
- Engine gains more power and an electric turbo wastegate.
- Subaru targets a top overall finish at the Nurburgring 24h.
Subaru has revealed its latest weapon for the Green Hell. The WRX NBR Challenge 2026 is set to compete at the 24 hours of Nurburgring, representing the latest evolution of the FA24-powered platform.
The model is a race-prepped version of the production WRX S4 with various modifications. The headline figure is a 6.5% increase in peak power compared to the 2025 model. This means the turbocharged 2.4-liter boxer engine now pushes out 395 hp (295 kW / 400 PS) and 590 Nm (435 lb-ft) of torque.

While it can’t match the 670 hp (500 kW / 680 PS) of the unrestricted Project Midnight, Subaru’s latest racecar is the most powerful factory-backed WRX to ever tackle the Nurburgring endurance race. Power is transmitted to all four wheels via a six-speed sequential gearbox and the symmetrical AWD system.
According to Subaru, the engineering team focused on refining controllability under extreme conditions. Beyond the power increase, the 2026 racecar features an electrified turbo wastegate to sharpen transient response.
Stability has been enhanced with a newly developed ABS unit for the brakes, a revised rear suspension roll center height, and more durable suspension ball joints.

The exterior looks similar to previous iterations with wide fenders, cannards, sharp bumper extensions, and a large rear wing stretching the vehicle’s length to 5,270 mm (207.5 inches). According to the company, aerodynamics have been slightly improved thanks to the redesigned mirrors.
Crucially, Subaru is not only aiming for the victory in the SP4T class of the WRX NBR Challenge, but also for the top overall finish, challenging rivals from the higher SP8T class.
What About Roadcars?
The reveal of the track-only beast is a sign of Subaru trying to keep the STI spirit alive through specialized road cars rather than a proper new version of the WRX STI.

A recent example is the limited-production WRX STI Sport# in Japan, which offers enthusiasts a sharper driving experience via an STI-tuned chassis, a manual transmission, and a blueprinted engine, albeit without a power bump.
Furthermore, there are a few rumors about a new STI hatchback, following the Performance-B STI Concept and a similar HiPerfX2 racecar for the Super Taikyu series.
