description Sono Sion Overview
The Sono Sion is a more accessible solar-powered vehicle, aiming to provide a practical and affordable option for everyday use. Integrated solar panels on the roof and hood contribute to range extension, reducing the need for frequent charging. Sono's community-driven approach and focus on practicality differentiate it from more luxury-oriented solar vehicles. While its performance may not match the Lightyear 0, the Sion's affordability and emphasis on sustainability make it a compelling choice for those seeking a greener transportation solution.
help Sono Sion FAQ
Was the Sono Sion ever put into mass production?
No. Sono Motors ended the Sion passenger-car program on February 24, 2023 after citing a lack of funding, so it is a canceled EV project rather than a car you can order new. ([Sono Motors announcement](https://ir.sonomotors.com/news-releases/news-release-details/sono-motors-commits-focus-exclusively-solar-tech-company-and-has-terminated-sion-program))
How much range were the Sion's solar panels supposed to add?
Sono's planned production design used a 54 kWh LFP battery with an estimated 305 km battery range. The company estimated about 112 km of solar range per week on average, with up to 245 km possible in favorable conditions.

Could the Sono Sion power other devices?
Yes, the planned vehicle included bidirectional charging and was designed to supply up to 3.7 kW for devices or other electrical loads. This was a planned feature of the canceled Sion, not a capability available from a production vehicle.

How was the Sono Sion different from the Lightyear 0?
Both projects used solar cells integrated into the vehicle body, but the Sion was presented as a practical, more affordable family EV. The Lightyear 0 targeted a much more premium, limited-volume market, while Sono Motors planned contract production with Valmet Automotive.
