How It Started
- Built a pre-prototype in a garage
- Raised €800,000 in our first crowdfunding campaign
- First generation of prototypes, 13,000 test drives across Europe
- 2nd crowdfunding campaign raising over €50,000,000 in 2019/2020
Accelerating the revolution of mobility by making every vehicle solar - that's the mission we've pursued from a small garage to powerful crowdfunding campaigns all the way to the U.S. stock market. For a world without fossil fuels.
We are convinced that solar mobility can become the next big thing. We therefore have set ourselves the goal of making our patented solar technology accessible to everyone. This requires state-of-the-art engineering, thorough testing and a lot of passion. The Sion's testing program includes series validation, homologation, crash tests, tests in different climates, optimization of solar technology and safeguarding, and refinement of driving dynamics on test tracks and public roads.
Many different tools are needed to be able to produce the Sion in series. Some reshape an object, others hold and fix a component, and some are needed to make certain jobs easier and faster. The first tools are already available.
Crashing the Sion breaks our heart. But we'll do everything for your safety. As part of the Sion's testing program the crash test program has already commenced.
We wouldn't have come so far if it wasnt for the engagement and courage of our unique Community. Dedicated people who believe in our mission of making every vehicle solar, commited to fight for a climate-friendly future.

We believe in transparency and exchange on eye-level. But what does our Community think about Sono Motors and the Sion?
The Sion excited me from day one. The pictures of the converted Twingo sparked my interest, so when the images and features of the first Sion prototype were made public, I was done for. In order to be mobile where I live in the countryside, I'll most likely make the Sion a 'village car' and have it support my home storage system at night.
For me, it is the first serious alternative to internal combustion engine that uses solar energy intelligently and as a power unit on a mass scale. I already found the idea of this start-up worth supporting in 2017. In this way, everyone can contribute to the preservation of our environment.
There are moments in life when you have to take a risk in order to shape the future for the better. Supporting Sono Motors financially to get the Sion on the road was such a moment for me. I trust Sono Motors to be serious about climate and environmental protection and to produce fairly.
The Sono Motors way of thinking "car-environment-life" convinced me immediately and changed my behavior. Why did my cars actually have to be so individual? What would really be important in the future? Design, paint, leather against functional form, simpler equipment, solar, bidirectional charging, repair aids, apps, everything important built in, even trailer coupling. That's so different, that's what the world needs. In the meantime, we have a solar system on the roof, my Sion and the Sono wallbox are still missing.
I've always wanted an EV since I converted my Reliant Robin to EV power in 2013 and this looks like the first family size EV that I could afford. And I would love to go camping with the Sion, always electricity and room enough to sleep in de back with the seats down. can't wait!
The founders' impressive motivation to develop and produce a partly solo-powered car. From a garage in Munich. Cool!
Because I wanted to build a solar car myself.
The possibility of using the Sion as a power storage unit, solar integration into the Sion but also other vehicle types,a power supply for camping or a power outage, the Community.
I definitely want one to replace my old car with ICE. the low impact on the environment and self charging are very appealing.
Refuelling with the sun is the future!
In the fist place the Sion fits perfectly in our two families renewable energy system. The 51 solar panels produce more electricity than needed for the shared heatpump and the electricity consumption of the two households. In the second place we share already a car which will be replaced by the Sion.
I think the concept of the car is good. The Sion is perfect for our family and driving profile.
I reserved my Sion because I like the idea of solar integration and I want to switch to an electric car in the medium to long term. I heard about the possibility of using an electric car as electricity storage for a house years ago during my vocational training. It's nice that Sono Motors is involved here with the new wallbox. The concept of electric cars to stabilise the power grid in Utrecht shows that the future is slowly becoming reality.
It breaks the mould of big car manufacturers and fossil fuels in a new way with shared mobility

I wanted to buy a Renault Twizy in 2016. But it soon became clear that it wasn't for me. While searching, I came across you guys and stuck with it.
I wanted to support the great idea and the courage you showed. And, I wanted to get this car!
The basic idea, the innovative spirit and your enthusiasm!
As far as car ownership is concerned, I have staying power. Photovoltaics on a car is simply convincing.
The only right automotive concept in the world.
The Sion is far out the best in class (and bidirectional!).
A fascinating concept!
Simplicity, vehicle to grid, integration of sharing, diy possibilities.
I am impressed by the self-sufficient mobility through solar integration, the idea of car sharing and the courage, energy and stamina of the founders.I like to support young people with innovative ideas!
I like the concept and it is an optimal car for us because of the solar integration and trailer hitch.
I am a young craftsperson and father and am therefore in need of a spacious and family-friendly vehicle. Due to climate change, I would like to get away from our diesel car as soon as possible. The concept of the Sion has convinced me completely. The bidirectional charging is not that interesting for me at the moment, but the easy possibility of sharing, the solar integration and the affordability including the follow-up costs are even more so.
For us, it's the perfect car, so we're happy to wait a little longer.

Because I find the corrupt car industry and its cronyism with politics intolerable. Because the whole industry around the car (oil industry, garages,...) is structured in a way that is hostile to consumers. What I like most about the Sion is that it breaks up these structures in order to realise climate-friendly and resource-saving mobility.
