- The GR Corolla has been upgraded with new brakes, revised suspension, and a full roll cage.
- Various aerodynamic appendages adorn the exterior of the hot hatch.
- Power comes from the same 1.6-liter turbocharged three-cylinder as the street-legal car.
The Toyota GR Corolla is one of the most potent hot hatches on the market and feels right at home on a racetrack. But simply having a hatch like this with track credentials wasn’t enough for Toyota and it’s gone ahead and developed a dedicated racing version of the GR Corolla to compete in the TC America Series, a popular touring car championship.

Numerous upgrades have been made to the GR Corolla to get it ready for track use. The team from the GR Garage in Mooresville, North Carolina, started out by fitting Alcon six-piston front and two-piston rear brake calipers that bite down on new discs. Bespoke MacPherson struts have also been installed alongside JRi dual-adjustable shocks.

Like any good race car, plenty of aerodynamic changes have been made. The front end has been subtly revised to include a new splitter, grille, and air intakes. The sides also rock new skirts, while found at the rear is a large rear wing affixed to the roof. A new bumper has also been crafted and includes a distinct diffuser.

Plenty of other upgrades have been made. For example, the vehicle’s drivetrain, power management, and ABS are controlled by new Bosch Motorsport electronics. There’s also an FIA-approved roll cage, an OMP fiberglass racing seat with a six-point harness, and an electronically activated fire extinguishing system.

The race car features the same 1.6-liter turbocharged three-cylinder as the road-going model and is equipped with Gazoo Racing’s new eight-speed direct automatic transmission and all-wheel drive.
“The opportunity to take the GR Corolla and make it a track-ready racecar with the team here at TGRNA was exciting project to tackle,” Toyota Gazoo Racing North America manager of Customer Racing, Mike Norem, said. “Working with our partners at SRO America as they established the updated 2025 TC America series, we knew that the GR Corolla was the ideal platform for this series and would provide the perfect opportunity for our team to continue to grow the GR sports car ladder in the United States.”
