GR Yaris specs
The GR Yaris is the perfect demonstration of how Toyota and its performance arm TOYOTA GAZOO Racing are committed to developing ever-better cars through motorsport. From the outset, this was not going to be just another hot hatch: this was a car that in engineering and design terms directly reaped the benefits of TOYOTA GAZOO Racing’s championship winning experience in the WRC.

A new engine, a new electronic all-wheel drive system and a tailor-made chassis were all part of the plan. When the production car reached the hands of the press and customers, the response far surpassed Toyota’s expectations. Since the model’s 2020 launch, more than 20,000 cars have been sold in Europe, with a 99% customer satisfaction rating. Most of those sold have been the Circuit version, hence the decision to focus on this specification for the new model. Customers include many performance car aficionados, who consider the GR Yaris to be worthy of a place alongside significantly more powerful prestige models in their collections. The GR Yaris is thus beyond categorisation; it is in a class of its own and an instant sports car classic.

The introduction of a brand-new eight-speed GAZOO Racing Direct Automatic Transmission is one of the most significant changes in the new GR Yaris programme, offered as an option to the established six-speed manual gearbox. In designing the new unit, Toyota focused on achieving the fastest possible downshift speed. Changing to automatic operation; using an automatic also lets the driver focus more strongly on steering and use of the brake and throttle pedals.

Where conventional gear shifting relies on sensing vehicle behaviour, such as deceleration g-force and speed, the new transmission’s optimised software is also finely tuned to sense how the driver is using the brakes and accelerator. By doing so, it anticipates when gear shifting is necessary even before changes in vehicle behaviour occur, so that gear selection reflects the driver’s intentions and is similar to how professional drivers operate.

In track testing, the new system proved its value, helping secure faster lap times than the manual transmission. Handling performance is supported by the standard provision of front and rear Torsen limited-slip differentials.

To address issues including the vulnerability of automatic systems to heat damage and the need to balance high shift speed with driveability, GR engineers carried out repeated materials and software revisions. The test programme included TGR World Rally Team drivers putting it through its paces on different surfaces, including snow-covered roads in Finland. The unit was also used in the Japan Rally Championship, the TOYOTA GAZOO Racing Rally Challenge and the Super Taikyu Series.

Increasing the number of gears from six to eight allows the transmission to have closer ratios. It also benefits from a new torque control system and a compact, high-response linear solenoid. Using highly heat-resistant material in the gear-shift clutch and adjustments tuning of the control software have produced world-class shifting speeds. Shifting in the D-range is of competition standard and the predictive gear selection function aligns perfectly with the driver’s intentions. Cooling requirements are addressed with the installation of an automatic transmission fluid cooler as standard.
Ogier Edition

The Ogier Edition GR Yaris has two new AWD control modes: Morizo and Seb. The Morizo mode has been developed by Morizo (Akio Toyoda) through his rally driving experiences. It is calibrated to help deliver consistent race times under acceleration, partial acceleration and braking. The Seb mode, developed by Ogier, uses the front and rear Torsen limited slip differentials and all-wheel drive to distribute torque to the rear axle so that the back of the car can be swung out with relative ease. This gives the driver a sense of being fully connected with the car and will help them achieve quicker times with high-speed driving body control.
The Rovanperä Edition has a unique Donut Mode, created specifically for the WRC’s youngest champion who is highly skilled in drifting and performing tyre-smoking donuts. Here, the new mode allows for easy driving and “door turns” with a constant, strong torque flow to the rear wheels.
