Overview

• Toyota adds 13.9 m of structural adhesive for a 32.7 m total, targeting greater body rigidity for high‑g overseas circuits based on Super Taikyu learnings.
• A high‑engine‑speed cool air duct feeds the secondary intake from the front grille to lower temperatures and stabilize output during sustained hard driving.
• Peak output remains unchanged at roughly 300 hp (304 PS) and 400 Nm, with six‑speed manual or eight‑speed automatic transmissions retained.
• A 2026 software program for 2023 cars will unlock about 30 Nm to match 400 Nm and revise GR‑Four settings, replacing Rear with a 50:50 Gravel mode and making Track adjustable from 60:40 to 30:70; rollout in Japan is slated for spring 2026 with pricing to follow.
• Japan orders are open now for early November deliveries with unchanged pricing; Toyota signals increased supply without the prior lottery, citing added UK capacity, and Toyota Australia says its upgraded GR Corolla arrives in early 2026.
