On 4th March 2019, Sono Motors, a German electric vehicle start-up, unveiled an updated production design of the Sion, an electric car with full-surface integrated solar cells. These solar cells are embedded in hard-wearing and resilient polymer, which also contribute to the vehicle’s design aesthetic. The Sion is aimed at the European market. Sono Motors started registering pre-orders for Sion and has successfully recorded registrations for more than 9,000 units. The company declared that it would initiate the production of Sion in Sweden by mid-2020.
