Bridgestone Corporation today announced that it will be supporting the 2025 Bridgestone World Solar Challenge (BWSC) with ENLITEN technology tires, which feature the first application of new recycled materials developed through co-creation with partners, increasing the ratio of recycled and renewable materials to over 65%. The company will supply these tires to 33 teams from 17 locations. 

The BWSC, which will take place August 24 through 31, is the world’s foremost solar car event. Held every two years, participants are challenged with traversing approximately 3,000 kilometers across the Australian continent using only limited solar power. Bridgestone has been the title sponsor of BWSC since 2013; this event underscores Bridgestone’s focus on accelerating innovation for next-generation mobility, including EVs and electric vehicles, as well as developing the engineers who will shape the future of mobility. 

For the 2025 BWSC, Bridgestone will supply tires with ENLITEN technology, which ensures the performance required for solar cars while further advancing sustainability. For the first time, Bridgestone has applied recovered carbon black and steel, which are recycled materials developed and produced through co-creation efforts focused on advancing recycling technology that 'renews' tires to raw materials. Furthermore, the company is evolving its sustainability initiatives throughout the value chain, such as reducing the number of tires used and introducing low-carbon tire shipment for contributing to a circular economy and carbon neutrality. 

Through the BWSC as a 'mobile laboratory,' Bridgestone will refine its technology, thereby strengthening future sustainable global motorsports activities. Additionally, by pushing the limits and challenging for excellence, alongside participating teams that share a passion to race, Bridgestone is committed to accelerating innovation for the future of mobility.
