Solar vehicle company unveils designs for 'Sion' electric car and 'Solar Bus Kit' for public transport, aiming to revolutionize green transportation
In a groundbreaking move, Munich-based organisation Sono Group N.V. (OTCQB: SEVCF) showcased two world premieres at their first "Celebrate the Sun" Community Event. The event marked the debut of the Sion, the world's first solar electric vehicle (SEV) for the masses, and the introduction of the Solar Bus Kit, a scalable B2B retrofit solution aimed at reducing fuel consumption and inner-city greenhouse gas emissions.
The Sion, a testament to Sono Group's pioneering mission to accelerate the revolution of mobility, is designed to turn vehicles into sustainable power plants on wheels. Its outer shell consists of 456 seamlessly integrated solar half-cells, enabling self-sufficiency on short journeys. The vehicle's battery allows for a maximum charging capacity of up to 75 kW (DC) and 11 kW (AC).
Sono Group's Solar Bus Kit is a B2B retrofit solution that can save up to 1,500 liters of diesel and up to 4 tonnes of CO2 per bus per year from the ~1.4 kW peak installation with a total size of about 8 square-meters of solar panels. This innovative kit allows subsystems like the HVAC to be partially powered by renewable energy, thereby saving fuel, CO2, and costs. The Solar Bus Kit is optimized for common 12-meter public transport bus types on the European market, including Mercedes-Benz Citaro and MAN Lion's City.
The Sion and the Solar Bus Kit are aligned with global trends toward decarbonizing transport, promoting renewable energy integration, and shifting to zero-emission mobility. The Sion enables personal transport with a significant solar charging component, reducing overall electric grid load and emissions. The Solar Bus Kit supports public and commercial transport's transition to cleaner energy, directly contributing to lowering urban air pollution and greenhouse gas emissions from high-mileage vehicles in cities.
As of 1st July 2022, Sono Group had reached over 19,000 direct customer reservations with a down-payment for the Sion. The company is partnering with 19 companies worldwide, including MAN Truck & Bus and CHEREAU, to implement its Sono Solar Technology on a variety of vehicle architectures such as buses, trailers, trucks, and electric transporters. Sono Group is also building its fleet of series-validation vehicles in Munich, ushering in the Sion's testing program.
Jona Christians, co-founder and CEO of Sono Group, stated that the Solar Bus Kit represents a milestone on their path toward a world without fossil fuels. With 19 B2B customer projects for solar integration, Sono Group is well on its way to making every vehicle solar, and its disruptive solar technology has been engineered to be seamlessly integrated into a variety of vehicle architectures.
However, as of July 2025, there are no direct search results specifically detailing the current status of the Sion solar electric vehicle or the Solar Bus Kit developed by Sono Group N.V. For authoritative and up-to-date information, consulting your organization’s latest corporate communications, sustainability reports, or press releases from Sono Group N.V. would be recommended.
