Sono Motors is on a mission to enable a revolutionary mobility system, where every electric vehicle is solar, shared, and independent from fossil-fuels. Today, an experienced specialist team is developing a forward-looking electric car that is suitable for daily use, the Sion. Both the Sion’s integrated solar technology and innovative mobility services will enable users to access clean mobility, harness solar energy and reduce CO2 impacts. 

Sono Motors was founded in 2016 and has rapidly grown to approximately 200 employees today. The team combines a range of burgeoning global talent with industry veterans, including former employees from BMW, Nissan, Chrysler, Daimler, Audi, Mozilla, Sixt, FlixBus and mytaxi. Since its foundation, the company has raised approximately € 100M through reservations and funding. The company released its first generation Sion prototype in 2017 and has amassed 13,000 reservations with advance payments. In 2018, Sono Motors was recognized as a Solar Impulse Foundation by the Solar Impulse Foundation. In January of 2020, Sono Motors successfully closed one of the largest community crowdfunding campaigns in Europe.

Sono Motors’ Sion intends to blend disruptive technology with affordability to enable individual contribution to global sustainability. The Sono solar technology replaces traditional paint with proprietary integrated solar panels that can form to various applications. Additionally, the Sion’s solar panels can add up to 245 km or 152 mi (112 km or 70mi on average) of additional driving range per week to the car’s battery. The Sion is expected to have the lowest TCO (total cost of ownership) in its category at the start of production, which is scheduled for the first half of 2023.
