There’s an update coming for the Toyota GR Corolla, but existing owners could soon benefit from some new software and extra dollop of torque.

Toyota says it has stiffened the body and improved the air intake based on what it learnt from running the car in the Super Taikyu Series.

In order to improve body rigidity without increasing weight too much, Toyota has applied an extra 13.9 metres of structural adhesive throughout the body, bringing the total amount to 32.7 metres.

While the automaker doesn’t quantify how much body rigidity has been increased, it states the GR Corolla can now “achieve stable driving performance” on race tracks outside of Japan, which “typically generate more-intense vertical and lateral g-forces than circuits in Japan”.

A cool air duct, which draws air from the front of the grille, has been added to the secondary intake, and is opened automatically at high engine speeds in order to keep the motor output steady even under sustained hard use.

Output from the 1.6-litre turbocharged three-cylinder petrol engine is unchanged at 221kW and 400Nm. As before all of that fury is channel to all four wheels via either a six-speed manual or eight-speed automatic transmission.
