Reconstructing from Scratch: The Hurdles of Re-Creating, Part 1
Reviving the Iconic Toyopet Racer: A Blend of Tradition and Technology
In a remarkable feat of automotive restoration, Toyota has undertaken a project to revive its first racing car, the Toyopet Racer, which dates back over 70 years. This initiative, a harmonious blend of heritage craftsmanship and modern fabrication technologies, is being spearheaded by a special project team at Toyota.
At the heart of this restoration lies the vehicle's suspension and related components, crucial for a car's safety, driving performance, and handling. The team, comprising engineers like Daichi Sugimoto from the Vehicle Electrical Architecture Development Department, and Ding Nan, the youngest member who joined in 2018, had a challenging task on their hands. They discovered that there were no blueprints for the suspension components of the Toyopet Racer, necessitating the design and construction of these parts from scratch.
The team's journey was not without its complexities. They had to determine the specifications for the brakes, a process that involved discussions among every member working on the restoration project. Takahiro Tashiro, who joined a Toyota-affiliated company in 2002 and transferred to the Vehicle Dynamics department in 2020, led the way in making strength calculations for the Toyopet Racer's suspension.
Tashiro and his fellow team members calculated the suspension strength by hand with pen and paper, considering various factors such as the material, mounting position, and spring rate. Their aim was to recreate the original vehicle's ride height, look, and feel, while ensuring the suspension system could withstand the estimated corner entry speed of around 100 km/h for the Toyopet Racer.
The task of designing and fabricating these parts fell to Ding Nan and Daichi Sugimoto. They employed a blend of traditional handcraft skills and modern digital fabrication processes to reproduce the suspension geometry and structure with precision. This careful balance allowed the restoration to honour the car's original design while incorporating modern manufacturing quality.
The Toyopet Racer, now on display at the Fuji Motorsports Museum, is a testament to the team's dedication and the power of blending tradition and technology. The project is part of Toyota’s broader effort to revive and celebrate its historic models using advanced monozukuri skills passed down through generations.
Throughout the process, the team's work has been documented in Toyota Times articles released in 2024-2025. These articles provide a fascinating insight into the collaborative effort of young engineers and veteran artisans working in Toyota’s Takumi Kobo (artisan workshop). The Toyopet Racer's precise sheet metal shapes and mechanical linkages, including suspension components, were essential to its performance and aesthetic authenticity, and were expertly revived by the team at the Takumi Kobo.
In conclusion, the Toyopet Racer project is a shining example of how tradition and technology can combine to create something truly remarkable. The focus is on a respectful, precise revival that honours the car's original design while incorporating modern manufacturing quality, a balance that is both challenging and rewarding.
