Toyota introduced the GR Corolla in 2022, and the hot hatch has continued to evolve through motorsport feedback, structural changes, cooling updates, and new transmission choices.
Now Toyota is taking the car further with the GRMN Corolla, the most focused version of the model yet. The smaller GR Yaris already received a GRMN version in 2022, while the GR Corolla had been waiting for its own harder-core version.
The new GRMN Corolla has been revealed as a limited-production model aimed primarily at Japan, North America, and Australia. Toyota has not announced final pricing or production numbers, but the message is already clear: this is not a normal trim package.
The GRMN Corolla is built around Nürburgring development, Super Taikyu racing feedback, less weight, more torque, stickier tires, sharper aerodynamics, and a two-seat cabin. Toyota did not just add badges and a wing. It made the GR Corolla more serious for drivers who plan to use the car hard.
Nürburgring Testing Shaped The Whole Package
Toyota says the GRMN Corolla was developed through Nürburgring testing, Super Taikyu racing experience, and simulator work. The goal was to make the car more stable and controllable at high speed, even over rough surfaces and heavy cornering loads.
The aerodynamic changes are functional, not decorative. The GRMN Corolla gets a carbon-fiber engine hood with a ventilation duct, carbon-fiber front fenders with ducts above the wheel arches, carbon-fiber front side spoilers, and a carbon-fiber rear wing with an angle-adjustment mechanism.
Toyota says those pieces were developed using knowledge gained from racing, including the hydrogen-engine GR Corolla that competes in Japan’s Super Taikyu Series. The focus is road holding, cooling, and stability rather than styling drama alone.
The suspension is also specific to the GRMN. Toyota fitted exclusive front and rear monotube shock absorbers with internal rebound springs, then tuned the setup through Nürburgring testing. The electric power steering and GR-Four all-wheel-drive control were also recalibrated for high-g cornering and high-speed stability.
The Cabin Is Built Around Weight Reduction
The most obvious interior change is the rear-seat delete. The GRMN Corolla becomes a two-seat performance hatch instead of a practical five-door hot hatch with extra power.
Toyota says the weight reduction totals 66 pounds compared with the base vehicle. U.S. preliminary specifications list the GRMN Corolla at 3,218.7 pounds, with seating for two.
The cabin receives GRMN semi-bucket sport seats trimmed in black and red Brin Naub suede and synthetic leather. Toyota also adds a dedicated flocked instrument panel and front pillars, carbon-fiber ornamentation on the passenger side of the instrument panel, Alumite Red accents, a GRMN-exclusive serial number plate, and Morizo’s signature on the dash pad.
Japan and Australia receive GRMN-exclusive full bucket seats, while Toyota notes that North American cars use semi-bucket seats. That difference keeps the car track-focused while recognizing that market specifications vary.
The Turbo Three-Cylinder Gets More Torque
The GRMN Corolla keeps Toyota’s G16E-GTS 1.6-liter turbocharged three-cylinder engine. Output remains 300 horsepower, but torque rises to 302 lb-ft in U.S. preliminary specifications.
Toyota focused on stronger midrange response for corner exit. The U.S. release says the engine was optimized to increase torque in the 4,000 to 4,600 rpm range, while Toyota’s global material lists the maximum torque band at 3,250 to 4,600 rpm in preliminary specifications.
The GRMN also gets an intercooler spray system to help maintain stable output during repeated full-throttle driving. That joins the cool-air duct already added to the evolved 2026 GR Corolla.
The only transmission is a six-speed intelligent manual with rev matching. Toyota also gives the GRMN a close-ratio setup to keep the engine in its strongest range during track use.
The tires matter just as much as the extra torque. Toyota fits 245/40ZR18 Michelin Pilot Sport Cup 2 tires, which are 10 mm wider than the tires on the base vehicle. Combined with the aero package, suspension tuning, and all-wheel-drive recalibration, the tire change points the whole car toward more grip and better consistency under hard use.
Toyota Is Also Developing A Morizo RR Version
The GRMN Corolla is the two-seat manual model, but Toyota is also developing a related five-seat GR Corolla Morizo RR concept model.
The Morizo RR uses the GAZOO Racing Direct Automatic Transmission instead of the GRMN’s six-speed manual. That gives Toyota another way to explore a more serious GR Corolla for drivers who want automatic shifting and more everyday practicality.
The five-seat layout makes the Morizo RR less extreme than the GRMN Corolla, but it also shows that Toyota is not done experimenting with the platform. One version pushes the car toward a two-seat track special, while the other keeps more of the normal hatchback layout.
For Japan, Toyota says sales negotiation requests for the GRMN Corolla are planned through the GR app around autumn 2026, with sales scheduled to begin in 2027. Toyota has not announced full pricing or final production volume.
The GRMN Corolla is already the most serious version of the car. With Nürburgring development, Super Taikyu feedback, a two-seat cabin, less weight, more torque, Cup 2 tires, carbon-fiber aero, and sharper suspension hardware, Toyota has turned the GR Corolla into a much more focused track-capable hatchback.
