With all TOYOTA GAZOO Racing sports cars firmly rooted in motorsports, it only makes sense that the GR Corolla’s drivetrain was born from the rigors of rally racing.

At the heart of the new GR Corolla is the GR-FOUR All-Wheel-Drive system, Toyota’s first sports all-wheel-drive system in over 20 years. Developed in collaboration with the TOYOTA GAZOO Racing World Rally Team and honed by WRC drivers, it delivers exceptional levels of traction and control with engineering designed to optimize drive power to each wheel, while also being simple and lightweight.

Made for rally, the GR-FOUR system is designed for a variety of conditions. Whether the driver is looking to adjust performance for dirt, rain or snow, or just in the mood for a different feel, the GR-FOUR system offers settings to match.

With the twist of a dial, GR Corolla can adjust four-wheel drive performance to fit the driver’s needs. For every-day situations, drivers can set a front/rear torque distribution of 60:40; for a more sport setting, balance can shift to the rear, with 30:70 distribution for a fun-to-drive quality on winding roads and circuits; and for maximum stability a 50:50 setting can be used for fast, competitive track driving on circuits or special stages. In each mode, the torque balance will automatically adjust in response to the driver’s inputs, vehicle behavior and road or track conditions.

The GR Corolla Circuit Edition is also equipped with front and rear Torsen Limited-Slip Differentials (LSD), which offer enhanced cornering performance and grip with control of left and right-hand drive torque distribution on the front and rear axles. Front and rear LSD is available as part of the Performance Package on the Core grade, with 4WD open differentials standard.

The GR-Four All-Wheel-Drive (AWD) drivetrain gives drivers a choice of 60-40, 50-50 or 30-70 power distribution to the front and rear wheels. GR Corolla will be offered exclusively in a manual transmission, staying true to its hands-on rally racing roots.

I love the fact that you can select the drive distribution, I'd probably just leave it on 30:70.

I'm curious if it retains the unlocking mechanism from the GR Yaris when the handbrake is pulled while moving.

That would be awesome if they carried that over to the GR Corolla.
