Powered by the Sun

456 half cells seamlessly integrated into the body of the car can add 112 km, on average (up to 245 km) per week, of driving range to the car's battery, through the power of the sun. This creates full self-sufficiency on short distances.

Flexible Charging

To charge the Sion to 80% takes around 35 minutes at a fast charging station. The Sion can also be recharged at any public charging station in Europe, via your regular home power socket or from another Sion! The vehicle's on-board bidirectional charger enables you to share your Sion's power to recharge other electric vehicles.

Sleek Interior

The Sion's comfortable interior and generous trunk offer plenty of room for you and your needs. At the same time, you can focus on the essentials – the clearly structured, understated interior design of the Sion impresses with its intuitive useability. The infotainment system with integrated connectivity and mobility services can be controlled centrally via the 10-inch touch display.

Power To Go

The Sion's bidirectional charging technology enables you to use it as mobile energy storage, wherever you are. Be that while camping, on the construction site, or simply at home. Via a regular household plug, the Sion can power all common electronic devices with up to 3.7 kW. It can deliver even more power when using a Type 2 plug, you will be able to power other electric cars up to 11 kW.

Simple & Professional Maintenance

  • Do it yourself. You can carry out simple repairs by yourself. Accompanying repair tutorials will be available on our website.
  • Disclosure of the reduced workshop manual enables an extensive network of independent workshops.
  • For all repairs in the high-voltage, photovoltaic and safety areas, we cooperate with Bosch Car Service. So your Sion is always in the best hands

100% Renewable Energy

Sustainability has become such a loaded buzzword. We can assure you - it hasn't for us. We care deeply about the earth, climate friendliness and the impact Sono Motors and the Sion will have on this planet. To reduce both our own and your footprint to a minimum, we will offset all unavoidable CO₂ emissions produced throughout the Sion manufacturing process. And, by the way, your Sion is going to be produced with 100% renewable energy.

Seamless Integration of Solar Cells

You think a solar car is some kind of a geek thing? That's absolultely not the case with our Sion. We have developed a technology that allows us to integrate solar cells almost invisible into the vehicle exterior. Long-lasting, scratch-resistant and efficient.

Energy Harvesting Vehicle

Why not use what’s already there. A total of 456 half cells can generate a peak power of 1.2 kilowatts. Sufficient for 112 km on average (up to 245 km) per week or an average 5,800 km per year.

Engineered for Safety

Made for maximum strength. The Sion's aluminium space frame keeps you safe. It's also lightweight, does not oxidize and is 100% recyclable.

Platform for Future Vehicles

We have developed a platform for future vehicles. Variable battery capacity and a 120 kW electric motor. Engineered for flexibility and high scalability.

Mobility and Energy Services

All-in-One App: Car Sharing, Ride Pooling, and Power Sharing.

Sono Motors App: Mobility and Energy Services

We offer a variety of services with the Sion, combining innovative mobility with sustainablity. Your smartphone enables you to share your Sion, electricity, or even a ride. The Sono Motors app is also your digital key for the Sion and the window to real-time vehicle data. The Vehicle Connectivity Module controls our vehicle's data connection, as well as the automatic emergency call service eCall.

Overview of Functionalities

  1. My Sion provides you up to date information about your Sion and enables the usage of the car without a key – all you need is a smartphone.
  2. Sharing your car may seem unusual in the beginning. But once you’ve tried Car Sharing, you’ll never go back. It’s totally up to you to decide for how long and with whom you would like to share your Sion.
  3. You don’t want to ride alone? With Ride Pooling you can offer other users a ride.
  4. Power Sharing makes sharing the energy stored in your Sion easy. You decide on how much electricity you are willing to share and at which price.

Everyone benefits from your Sion as a result – including your wallet and, most importantly, the environment.


We're developing the Sion in collaboration with well-known partners in the automotive industry.
