The GR Yaris Aero Performance Package , announced by Toyota on September 12, 2025, and scheduled for release on October 1, is a high-performance model that incorporates a generous amount of technology cultivated in the WRC (World Rally Championship). Six dedicated items proven in the field of motorsports have achieved an astonishing performance improvement , reducing lap times at Fuji Speedway by approximately one second .

Organizing names to make them easier to understand
The GR Yaris has been called an “evolution model” until now, but the name will be revised from the 2025 model:
- Type 20 : Model initially released in 2020
- Type 24 : 2024 improved model (an evolution of the previous model)
- Type 25 : Latest improved model for 2025
This name change gives the impression of being like a tank, but it is a natural progression as a “fighting car” that competes in Super Taikyu, All Japan Rally, Nürburgring 24 Hours, and WRC.

Evolution of the “Type 25” standard specifications
gr yaris aero performance package
Test drives at Sodegaura Forest Raceway revealed that the Type 25 boasts a significantly improved quality . A 700km test drive on public roads also confirmed the following improvements:
- Improved sense of unity with the vehicle
- Improved tire ground contact
- Enhanced ability to handle uneven road surfaces
- Reduce fatigue during long drives
Key points of chassis improvements
- Rear suspension member x body fastening bolt head size expansion
- Added rib shape to front lower arm x lower ball joint bolt flange
- Improved flange thickness for rear shock absorber and body fastening bolts
- Optimization of shock absorber damping force
- Pursuing a linear feel by changing the EPS program
Evolution of the GR-DAT (8-speed AT)
The Direct Automatic Transmission (GR-DAT) has been improved with the following features to provide a more refined feel:
- Increased engine speed for downshifting while driving in D range
- Reduced paddle shifting time
- Rev hit operation time extended
- Optimized shift-up timing for uphill gradients
In particular, the torque limit, which was notorious as a “punishment control,” has been significantly improved, making the use of paddle shifters more practical when driving on a circuit.
Impressions of a car equipped with the Aero Performance Package
Vehicles equipped with the Aero Performance Package, which incorporates a special EPS program, have been praised for their “high level!”
Changes in driving performance
- Solid steering response
- Significant improvement in four-wheel ground contact
- Dramatic improvement in front road feel
- A revival of the old “20-type” feel
- Rear behavior is smooth and predictable
According to the test drive report, it is strongly recommended that “If you choose the Type 25 and plan to have fun on the circuit, be sure to add the Aero Performance Package!”
Technological advances and motorsport feedback
Developed in collaboration with professional drivers
Developed in collaboration with Kazuya Oshima to solve the issues at Fuji Speedway:
- Improved braking behavior at TGR corner (first corner)
- Eliminate understeer at Green Fight 100R corner
- Improved steering response
Utilizing knowledge from the motorsports field
- Aerodynamic improvement ideas from Super Taikyu Series cars
