Real-Time Telemetry & Data Collection
Utilizing advanced onboard sensors and data loggers on the Rally2 platform to capture precise metrics on tire carcass temperature, pressure fluctuations, and cornering loads under extreme racing conditions.
R2R Estonia OÜ
Welcome to our website!
This company, based in Estonia, competes in rallies across Europe and manages a rally team. It is run by rally driver Hiroki Arai, the 2020 and 2024 All-Japan Rally Champion.

2027
Starting in 2027, our team is launching a comprehensive campaign in the FIA European Rally Championship (ERC). This project combines high-level motorsport competition with rigorous, real-world Research & Development (R&D) to support next-generation tire technologies. For this project, we are deploying a brand-new Toyota GR Yaris Rally2, scheduled for delivery in January 2027.
Operating as a professional technical partner for our tire manufacturing client, we will tackle the most demanding gravel and tarmac stages across Europe using this state-of-the-art competition vehicle.
Our primary business mission is to generate high-fidelity, actionable data for tire development. Through a full-season entry in the ERC with the GR Yaris Rally2, we provide the following technical solutions to our partner manufacturer:
Utilizing advanced onboard sensors and data loggers on the Rally2 platform to capture precise metrics on tire carcass temperature, pressure fluctuations, and cornering loads under extreme racing conditions.
Executing rigorous testing on a wide variety of European terrains—from the fast, smooth tarmac of Central Europe to the rough, loose gravel of Southern and Northern Europe.
Assessing the durability, grip degradation, and performance limitations of prototype compounds to accelerate the manufacturer's R&D cycle.
To ensure operational excellence and transparent business execution, our project follows a structured roadmap:
Finalizing team structure, technical engineering staff, and procurement of the Toyota GR Yaris Rally2 (invoicing phase).
Official delivery and shakedown of the GR Yaris Rally2; formalization of the R&D Service Agreement with the tire manufacturer.
Full-season entry in the FIA European Rally Championship (ERC), executing ongoing data delivery and feedback loops.
