Although the World Solar Challenge and the Sasol Solar Challenge have been cancelled, the American Solar Challenge and a special iLumen European Solar Challenge are going ahead. Here, as a placeholder, is a list of 24 European teams from 11 countries (including Turkey) – 15 Challengers and 9 Cruisers. None of them have registered for ASC, but about half of them are likely to compete in iESC in September (others might participate in the Albi Eco Race in October). You may wish to follow the official iESC social media at

In recent news, PUT from Poland have revealed their Cruiser Klara, Chalmers have revealed a tadpole render, Twente have announced that they are also building a three-wheeler (called Red Horizon), and HUST have revealed a three-fairing design.
