It’s still early days, but here is a list of 47 cars (from 25 countries; 32 Challengers and 14 Cruisers) likely to attend the Bridgestone World Solar Challenge in October this year. There are some familar names as well as some newcomers (AgniRath from India, SOLO from Korea, Wakayama from Japan, aCentauri from Switzerland, Solaride from Estonia, and Ascend from Australia). Check out the new design by JU!
This list is a work in progress, and the team numbers are mostly guesswork.
