Recycled materials, sustainability and future technologies in the most challenging solar car race
Bridgestone returns as title partnerof the prestigious Bridgestone World Solar Challenge (BWSC) 2025, which will take place from 24 to 31 August in Australia. This time, the company is taking a step forward – it will deliver special tyres with ENLITEN technology, which for the first time use new recycled materials created in collaboration with leading industrial partners.
A total of 33 teams from 17 countries will benefit from the new generation of tyres, which increase the share of renewable and recycled raw materials to over 65%. This is a clear example of Bridgestone’s commitment to sustainable mobility and technological innovation.
The Solar Race as a Mobile Laboratory
The BWSC is not just a race – it is a test bed for the latest technologies. Participants must cover nearly 3,000 kilometres across the Australian outback, relying solely on solar energy. Bridgestone uses this platform to test future products and solutions in real-world conditions – from recycled materials to low rolling resistance rubber compounds.
