2026 GRMN Corolla Gets Track Ready Upgrades
Toyota has taken the GR Corolla formula to a new level with the introduction of the GRMN Corolla, a machine built for drivers who want the sharpest and most focused version of the hot hatch yet. While the standard GR Corolla has already earned a reputation for delivering serious performance, the new GRMN model pushes things further with additional engineering, track inspired upgrades, and a stronger connection to Toyota’s motorsport programs.
At the heart of the GRMN Corolla is the familiar turbocharged one point six liter three cylinder engine. Power remains at three hundred horsepower, but torque climbs to three hundred two pound feet in North American specification. That increase may look small on paper, but Toyota says the improvements go beyond the headline number. Engineers focused on delivering stronger mid range performance and more responsive acceleration where drivers use it most during spirited driving.
Interestingly, some of those gains came from lessons learned while developing Toyota’s hydrogen powered GR Corolla race car. Knowledge gained from competition helped engineers improve the engine package while maintaining reliability during demanding track sessions. To support sustained performance, the GRMN also receives an intercooler spray system designed to keep temperatures under control when the car is pushed hard.
Weight reduction was another major priority. Following a philosophy similar to the Morizo Edition, Toyota removed the rear seats entirely. The change cuts approximately sixty six pounds from the vehicle while emphasizing the GRMN’s mission as a driver focused machine. It may sacrifice everyday practicality, but the result is a more dedicated performance car aimed at enthusiasts who value driving excitement above all else.
The exterior immediately separates the GRMN from the regular GR Corolla. A more aggressive aerodynamic package includes front fender vents, hood ducts, front side spoilers, and a large adjustable rear wing. The wing offers five levels of adjustment, allowing owners to fine tune the car’s aerodynamic balance for different driving conditions and track environments.
Toyota also upgraded the wheel and tire package. The standard GR Corolla’s Michelin Pilot Sport five tires give way to wider Michelin Pilot Sport Cup two rubber measuring two hundred forty five slash forty ZR eighteen. These high performance tires are mounted on lightweight forged eighteen inch wheels finished in matte bronze. The result should be improved grip, sharper turn in response, and greater confidence during aggressive cornering.
Underneath the bodywork, engineers revised the suspension with new monotube shock absorbers at both ends. Additional tuning was carried out for the all wheel drive system and electric power steering. Toyota’s goal was simple: create the most capable and rewarding GR Corolla ever offered to customers.
The interior continues the focused theme. North American models receive supportive semi bucket sport seats, while some international markets benefit from an even more aggressive full bucket driver’s seat. Carbon fiber trim on the passenger side of the dashboard and distinctive red accents throughout the cabin remind occupants that this is not an ordinary Corolla.
Although Toyota has not confirmed production numbers, the serial number plate mounted near the manual transmission shifter suggests that the GRMN Corolla will be a limited production model. That exclusivity is likely to make it one of the most desirable Gazoo Racing vehicles in recent years.
However, the story does not end with the GRMN. Toyota also revealed the GR Corolla Morizo RR, a separate project that points toward another direction for the performance hatchback. Unlike the GRMN, the Morizo RR keeps its rear seats and maintains a practical five seat layout. It also introduces something many enthusiasts have been curious about: an automatic transmission option.
The Morizo RR is being developed exclusively with Toyota’s eight speed Direct Automatic Transmission. While final specifications have not yet been released, Toyota describes it as the ultimate five seater within the GR Corolla family. Early images reveal styling heavily inspired by the GRMN, including a carbon fiber hood, rear wing, aggressive front aero components, and unique badging.
The Morizo RR may not be as extreme as the GRMN, but it demonstrates that Toyota is far from finished evolving the GR Corolla platform. More than four years after the model first appeared, engineers are still finding ways to improve performance, refine driving dynamics, and keep the hot hatch competitive in a rapidly changing automotive world.
For enthusiasts, that is excellent news. Whether buyers prefer the stripped out track focused GRMN Corolla or the more versatile Morizo RR, Toyota continues to prove that driver engagement remains a top priority at Gazoo Racing.
