TOYOTA has announced a suite of performance-focused upgrades for its GR Corolla hot hatch, with the refreshed model due to arrive in Australian showrooms in early 2026.
Drawing on the brand’s motorsport experience, including development work in Japan’s Super Taikyu Series, the latest updates aim to improve driveability, cooling efficiency and overall handling when the car is pushed to its limits.
A major change is a significant boost in chassis rigidity. Toyota has increased the use of structural adhesive by 74 per cent—now totalling 32.7 metres throughout the vehicle—concentrated around the underbody and rear wheel wells. The strengthened structure is designed to better manage the severe vertical and lateral G-forces encountered during hard driving, while also improving everyday responsiveness.
Engine performance has also been refined. A new cool-air duct has been added to the secondary intake, opening at high revs to draw in outside air from the front grille and help stabilise temperatures. Toyota says this allows the 1.6-litre turbocharged G16E-GTS engine to maintain consistent performance under high loads for longer bursts.
Inside, the GR Corolla receives an audio upgrade, with the existing eight-speaker JBL system expanded to nine speakers through the addition of a cargo-area subwoofer. Noise management has been improved via updated Active Noise Control, while a new Active Sound Control system enhances engine tone in three selectable patterns tied to drive modes.
The updated model retains its 221kW/400Nm turbo triple, paired with either a six-speed manual or eight-speed automatic, and continues to offer all-wheel drive with limited-slip differentials for maximum traction.
