The Toyota GR Yaris Rally1 is a Rally1 car built by Toyota Gazoo Racing WRT that has been driven in the World Rally Championship since 2022. The prototype car is based on the GR Yaris production car. The car won the Autosport Awards Rally Car of the Year in 2022.
The Toyota GR Yaris Rally1 is an advanced iteration of the high-performance rally car, developed in compliance with the FIA Rally1 technical regulations introduced in 2022. This vehicle represents the evolution of the previous World Rally Cars, which were the pinnacle of rally racing until the end of 2021. Notably, the GR Yaris Rally1 is among the first generation of Rally1 cars to incorporate hybrid technology.
Following its debut, hybrid units were phased out due to new regulations that came into effect in 2025; however, the commitment to sustainable motorsports continues with the use of 100 percent sustainable fossil-free fuel.
The chassis of the GR Yaris Rally1 employs a spaceframe design, ensuring high safety standards for both the driver and co-driver. Features that enhance the car's driving stability, such as side skirts and a large rear wing, have been retained from its predecessor. The vehicle is equipped with a four-wheel drive transmission system, incorporating mechanical differentials at both the front and rear. The fundamental construction of the car, adhering to Rally1 regulations, includes a five-speed gearbox with a mechanical shift and a short suspension travel, consistent with specifications until 2024.
The GR YARIS Rally1 features a power unit broadly consistent with the 2024 model, utilizing a 1.6-liter inline 4-cylinder direct-injection turbocharged engine. However, due to regulation changes, the diameter of the intake air restrictor decreased from 36 mm to 35 mm for the 2024 season. Additionally, the removal of the hybrid unit has led to a reduction in maximum output from over 500 PS to over 370 PS. This absence of a hybrid boost has necessitated adjustments to the engine's performance characteristics, resulting in changes to the exhaust system and camshafts for the 2025 model year.
A review of the gear ratios and other modifications have been implemented to optimize the vehicle's performance. Eliminating the hybrid unit has also contributed to a significant reduction in the vehicle's minimum weight, which is now 1180 kg, a decrease of 80 kg from its predecessor. Consequently, the GR YARIS Rally1 has evolved into a rally car with enhanced agility and driving performance.
