TOYOTA’s Gazoo Racing (GR) division has evolved into a performance brand in its own right, especially following the debut of the GR GT in late 2025. Yet the company continues to refine its lineup of high-performance models.
After transforming the GR Yaris into the track-focused GRMN Yaris, Toyota has now turned its attention to the GR Corolla. The result is the new GRMN Corolla, the most hardcore version yet of the world’s best-selling compact car.
The GRMN Corolla takes the GR Corolla’s aggression to another level.
Toyota Motor Corp. Chairman Akio Toyoda said any model carrying the GRMN badge must be capable of handling the Nürburgring. After all, GRMN stands for “Gazoo Racing Masters of Nürburgring.” To exceed those expectations, the GRMN Corolla was also developed using lessons learned from Toyota’s participation in Japan’s Super Taikyu endurance racing series.
The result is a significantly stiffer chassis, with structural adhesive coverage increased to 32.7 meters. The body has also been optimized for sustained high-speed driving. Functional air ducts have been added to the hood and fenders, while new front side spoilers and a larger rear wing help improve stability and downforce. The rear wing can also be adjusted through five different angles depending on driving conditions.
Inside, the GRMN Corolla features a predominantly black cabin accented by red trim. Suede covers much of the interior, complemented by synthetic leather and carbon-fiber accents. A Morizo logo on the dashboard further distinguishes the flagship model. Standard equipment includes a 12.3-inch digital instrument cluster and an 8-inch infotainment touchscreen with wireless Apple CarPlay and Android Auto.
In pursuit of weight reduction, Toyota removed the rear seats altogether, effectively turning the GRMN Corolla into a two-seat performance hatchback with a large cargo area.
Toyota’s Super Taikyu race car runs on hydrogen combustion technology, and the company says its ongoing development work has helped improve the production car’s 1.6-liter turbocharged three-cylinder engine.
Peak torque rises by 15 Newton-meters (Nm) to 415 Nm, while output remains unchanged at 304 horsepower (hp). The added torque is concentrated between 4,000 and 4,600 rpm, improving acceleration when exiting corners.
Power is sent to all four wheels through a six-speed manual transmission, the only gearbox available. To improve durability during extended track sessions, Toyota has fitted an intercooler spray system adapted from the GR Yaris.
The suspension has also been extensively revised. The GRMN Corolla receives new front and rear monotube dampers with rebound springs, while the bump stops have been re-tuned to better cope with the Nürburgring’s notoriously uneven surface.
Neither the steering nor the GR-Four all-wheel-drive (AWD) system escaped modification. Toyota revised the steering rack to maintain consistent assistance under high cornering loads. Meanwhile, the AWD system has been recalibrated to improve rear torque distribution during straight-line acceleration and enhance stability during high-speed turn-ins.
Unlike previous GRMN models, the GRMN Corolla will be sold in a wider range of markets, though production will remain limited. Toyota has so far confirmed availability in Japan, North America, and Australia.
