Toyota’s Gazoo Racing division has announced a series of detailed updates for the GR Corolla, promising sharper handling, improved cooling and a more immersive driving experience when the upgraded model lands in Australian showrooms in early 2026.

Drawing on insights from Toyota’s extensive motorsport involvement, including Japan’s demanding Super Taikyu Series endurance races, engineers have fine-tuned the GR Corolla to deliver even greater performance and control for drivers who like to explore the car’s limits.

The key structural upgrade involves a 74 per cent increase in the use of structural adhesive, now totalling more than 32 metres throughout the chassis. The reinforcement is focused around the underbody and rear wheel arches to better withstand the intense vertical and lateral forces experienced during high-speed cornering and track driving.

Toyota says the enhanced rigidity improves stability and steering response while deepening the connection between driver and machine – whether on a racetrack or a daily commute.

Engineers have also addressed thermal performance with the addition of a new high-speed intake duct. Opening under heavy throttle, it channels cooler outside air from the front grille directly into the turbocharged 1.6-litre three-cylinder engine. This helps maintain stable operation during extended high-load driving, ideal for spirited or track use.

Inside the cabin, the 2026 GR Corolla gains a nine-speaker JBL® premium audio system – up from eight speakers – thanks to the inclusion of a subwoofer in the cargo area for deeper, cleaner sound reproduction.

Toyota has also refined the Active Noise Control system to reduce unwanted engine and road noise, while introducing Active Sound Control for the first time. This feature enhances the engine note according to throttle input and drive mode, offering three selectable sound profiles with adjustable volume levels.

The GR Corolla continues to pack a punch with its 221 kW / 400 Nm turbocharged engine, paired with either a six-speed manual or an eight-speed automatic transmission. Power is channelled to all four wheels through Toyota’s GR-Four system with limited-slip differentials, ensuring maximum traction and agility.

Pricing and detailed specifications for the upgraded GR Corolla will be announced closer to its Australian launch in early 2026.
