2021 Official Regulations
The aim of the Bridgestone World Solar Challenge is to stimulate research into, and development of, sustainable road transport. The Bridgestone World Solar Challenge is primarily a design competition. The regulatory philosophy is to provide the parameters on which to base the design, rather than specify exactly how to build a solar car. Science and technology evolve and to encourage the most innovative ideas, event requirements also evolve.
Participation in the 2021 Bridgestone World Solar Challenge calls for the design and construction of a solar car within given design parameters and driving the solar car across the continent of Australia in accordance with these regulations.
Each Bridgestone World Solar Challenge is different. Revisions for the 16th Edition retain the clear distinction between Challenger and Cruiser Classes: Challenger Class cars will be efficient, and Cruiser Class cars will be both efficient and practical.
