Toyota has introduced subtle yet impactful updates to the GR Yaris for the 2025 model year. The compact performance car continues to captivate enthusiasts with its dynamic capabilities, though it remains unavailable in certain markets like the UK. These enhancements aim to elevate the driving experience by fine-tuning existing features. Among the changes is a recalibrated automatic transmission that broadens the rev range for downshifting, addressing previous feedback from drivers who desired quicker gear changes. Additionally, improvements have been made to how the vehicle handles uphill acceleration in automatic mode.

The mechanical adjustments extend beyond the gearbox. Toyota engineers have redesigned suspension bolts with wider heads and thicker flanges, contributing to enhanced steering precision and straight-line stability. To complement these changes, the shock absorbers' damping force has been modified, striking a balance between better chassis control and improved ride comfort. Moreover, professional racing driver Kazuya Oshima contributed to refining the power steering settings, ensuring a more responsive and engaging drive. A notable addition is the optional rally-style vertical handbrake, designed to make controlled slides easier during spirited driving sessions on closed tracks.

While the exterior largely retains its original design, an optional Aero Performance Package debuts in Japan, featuring aerodynamic enhancements such as a vented aluminum hood and adjustable rear spoiler. Despite these cosmetic upgrades, the core appeal of the GR Yaris remains unchanged. As the upgraded model becomes available across Europe, anticipation grows for its potential reintroduction to the UK market. These refinements underscore Toyota's commitment to delivering high-performance vehicles that meet both driver expectations and modern safety standards, reinforcing the brand's dedication to innovation and quality.
