A spacious electric car with a range of up to 255 kilometers that charges itself through the power of the sun.

Powered by the Sun

Thanks to more than 248 solar cells seamlessly integrated into the body of our solar car. The Sion can add 112 km on average (up to 245 km) of driving range per week through solar energy to the car’s battery. Full self-sufficiency on short distances.

Flexible Charging

It usually takes 30 minutes to charge up to 80% at a fast charging station. Additionally, the Sion can be recharged at any public charging station in Europe, including your regular power socket at home – or any other Sion. Thanks to a bidirectional onboard-charger, the Sion will be able to share its power to recharge other electric vehicles.

Your Range

The Sion's liquid cooled battery has a capacity of 35 kWh, which enables you to drive 255 kilometers according to WLTP standard on a single charge – depending on the weather and your driving style. The perfect range for everyday use.

One Size Fits All

Comfort for you and your family, a tow bar for holidays and a large trunk for weekend shopping. The car for every occasion.

Sleek Interior

The Sion offers plenty of room for you and your needs with its comfortable interior and generous trunk. 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

Thanks to the bidirectional charging technology, you can use your Sion as mobile energy storage wherever you are. While camping, on the construction site, or simply at home. A regular household plug can be used to power all common electronic devices with up to 3.7 kW. The car can deliver even more power when using a Type 2 plug, powering high-voltage devices with up to 11 kW.

Low Cost Maintenance

Our clever 3-step maintenance system keeps repair costs as low as possible.

  1. DIY is back. Standard replacement parts can be changed by yourself without needing much prior knowledge.
  2. By publishing a workshop handbook, we make it possible to establish an extensive network of independent mechanics.
  3. For any repairs involving high-voltage or body parts, we cooperate with a well-known European service provider.

100% Renewable Energy

Sustainability became a buzzword. Well, for us it isn’t. We care about the earth, climate friendliness and the impact Sono Motors and the Sion will have on this planet. To reduce our 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? Not 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 248 solar cells can generate a peak power of 1.2 kilowatts. Sufficient for 112 km on average (up to 245 km) per week or on average 5,800 kilometers a year.

Engineered for Safety

Made for maximum strength. The Aluminium Space Frame of the Sion keeps you safe. It's also lightweight, does not oxidise and is 100% recyclable.

Platform for Future Vehicles

We have developed a platform for future vehicles. Variable Battery Capacity. 120 kW electric motor. Engineered to be flexible and highly scalable.

Mobility and Energy Services

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

Sono App: Mobility and Energy Services

We offer a variety of services with the Sion, combining innovative mobility with sustainablity. With your smartphone, you can share your Sion, electricity, or a ride. The Sono app is also your digital key for the Sion and the window to real-time vehicle data. The data connections of our vehicle as well as the automatic emergency call service eCall are controlled by the Vehicle Connectivity Module.

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.
