The 2026 Toyota GRMN Corolla is the most extreme take yet on the hot hatchback, but the upgrades balloon the car's price to $65,655. The track-focused GR Corolla ditches the rear seat and adds more cooling vents, redesigned suspension, an adjustable rear wing, and a touch more torque. The model will officially be available later this summer, with Toyota limiting production of the GRMN Corolla to just 730 units globally.
