Toyota Motor Corporation premiered the new GR Yaris - a homologation model for the FIA World Rally Championship car. Learning from competing in the WRC, Toyota developed the GR Yaris together with Tommi Makinen Racing from the ground up. The company has already kick-started bookings for the car in Japan. Toyota Gazoo Racing, have come to know, through the WRC, various types of roads regularly used by its customers around the world. Thus, the GR Yaris was developed to be a car that responds to driver demand on all types of roads worldwide. Based on the knowledge and know-how accumulated by Toyota Gazoo Racing, the birth of the GR Yaris is the result of giving form to what has been learned from the World Racing Team and the GR Yaris is meant to be a car that allows anyone to drive as one wishes with peace of mind.
Built from learning of the WRC, the Toyota GR Yaris gets a high-rigidity body
The GR Yaris employs a sports 4WD platform based on the TNGA approach. Taking feedback from real WRC experiences, the GR Yaris has been built from scratch to achieve a high-rigidity body of highly refined balance while also optimizing front and rear suspension geometry. By combining its platform with the "GR-FOUR" sports 4WD system, efforts were made to achieve a high level of dynamic performance. Furthermore, the upper body, in addition to using aluminium for the hood, trunk lid, and door panels, features a carbon fibre-reinforced plastic roof panel formed using the sheet moulding compound method, which accommodates a high level of freedom in shape design.

Among the GR Yaris' available engine variations, the 1.6-litre in-line three-cylinder direct-injection turbo engine is a newly developed compact and light high-power unit. In addition to the high-speed combustion of a TNGA engine, by increasing engine revolutions through the use of lightweight moving parts, and by optimizing the turbocharger and other elements of the air intake and exhaust system, efforts were made to achieve the world's highest maximum output for a three-cylinder engine of 269 bhp as well as to achieve continuous provision of abundant torque over a wide range of engine speeds. Combined with a six-speed iMT (Intelligent Manual Transmission), which makes rhythmical gear changes possible, this engine provides overwhelming acceleration and allows users to experience an increase in engine revolutions that feels good.

The GR Yaris also sports the newly developed GR-FOUR sports 4WD system, which uses a front and rear variable driving force system enabled by a multi-plate clutch, transfers the power of the new engine to all four wheels with minimal loss. Freedom of driving force distribution between the front and rear wheels has been increased, making possible delicate control that matches road surface conditions. These advancements have resulted in a higher level of stand-out driving stability.
Production will be carried out on a dedicated production line at Toyota's Motomachi Plant.
