Frequently Asked Questions

Our prototypes are already similar to the end product in terms of design, construction and features. In the course of series development, the vehicle concept was optimized and the technical equipment adapted. For example, the all-round visibility was improved, the interior revised and viSono fully integrated into the body of the Sion.

We’re not expecting to have a right-hand drive version of the Sion on offer during the initial production cycle. Depending on demand and the Sion’s success, we may potentially manufacture a right-hand drive model in the future.

The Sion is expected to weigh 1.4 tonnes, including battery. We’ll announce the final details as soon as they become clear during our preparations for series production.

Sure.

The Sion’s towing capacity will be 750 kilograms unbraked.

We’re pursuing a single-product strategy with the Sion. That means we’re only offering one configuration at present. When it enters series production, however, you’ll be able to install a tow bar on the Sion. We’ll offer this as an aftersales accessory that you can attach yourself.

The Sion will only be offered in black, in keeping with our single-product strategy. We let the community take the decision on the car’s color a few months ago as part of an official community poll.

Following the introduction of automatic emergency dialling (eCall) across all of Europe, every new vehicle in Europe must from 2018 onwards possess an integrated SIM card that is connected to the Internet and meets ECE homologation specifications. In the event of an accident, which we sincerely hope doesn’t occur, an emergency call will automatically be placed. The eCall is being implemented with the aim of significantly increasing the chances of survival of vehicle occupants who sustain major injuries.

The Sion uses this Internet connection to provide additional information (goSono app) and functionality (carSharing, rideSharing and powerSharing). It goes without saying that the protection of your personal data is just as important to us as it is to you.

It’s easy to charge electric cars. For your Sion there are three methods to choose from, among the following plug types:

CCS plug: can be found at rapid charging stations for charging with up to 50 kW (DC).

Type 2 plug: can be found at all common charging stations for charging with up to 11 kW (AC) and output (bidirectional charging): 11 kW (AC).

Household plug (SchuKo): for charging with what we expect will be up to 3.7 kW (AC).

The Sion will come with a Type 2 plug and a CCS plug system. In addition, we expect that the Type 2 cable will be included for an additional fee. CCS charging cables are generally integrated into rapid charging stations.

The time taken to charge depends on the method used. The three different methods for charging the Sion are:

1. Using a household plug (SchuKo): with this plug, the time taken to fully charge a completely empty battery to 100 percent can be up to 13 hours, depending on the capacity of the socket. Perfect for charging your Sion overnight.

2. At a charging station: this method takes 2.5 hours to provide an 80 percent charge and 3.5 hours for 100 percent. Charging stations such as these are highly common, especially in inner-city areas.

3. At a rapid charging station: here your Sion will be 80 percent charged in 30 minutes, though you’ll need to allow for another 30 minutes for a 100 percent charge. Nevertheless, an 80 percent charge provides 200 kilometers range, which is often enough to cover the distance to the next rapid charging station. Rapid charging stations are now also widespread and can be found at almost all motorway rest areas and transport hubs.

Yes! Simply use the appropriate charging adapter to charge the Sion at any household power socket. However, we recommend you install a charging station (wallbox) to charge your car. This charging station adapts to the charging capacity of your electrical installation and tells your Sion the maximum current it can charge with.

The Sion system supports the following plugs: CCS, Type 2 (EN 62196) and European household plugs (SchuKo). For you to charge your Sion with your existing SAE J1772 plug, you will need to purchase an adapter.

The Sion comes featuring a big, family-friendly trunk with a volume of around 650 liters. The rear seats can be folded down to make for an even larger volume of around 1,250 liters.

Yes, we expect that the driver’s seat will be able to be adjusted up and down as well as forwards and backwards. The car will be fitted out ergonomically in line with standards (95th percentile person) commonly used in the automotive industry.

Our prototypes are already similar to the final product in terms of design, construction and features. In the course of the preparation for series production, the vehicle was optimized at various levels. In particular, the interior and the general finishing of the Sion have undergone a significant qualitative upgrade, this includes the seats.

Appropriate connectors (ISOFIX) for child safety seats are planned. The number of child safety seats possible will then of course depend on the size of those seats.

The Sion has folding rear seat backs, devided in the proportion 60/40.

The Sion will leave the factory as a five-seater. Unfortunately, it will not be possible to install extra seats.

The Sion will be equipped with front-wheel drive.

Due to our single-product strategy, we are unfortunately not offering any optional layouts for the Sion at the moment. The car will be equipped with front-wheel drive.

The Sion is, above all, an electric car designed for everyday, urban use. Even so, we’re planning to equip the car with a powerful 120 kW motor so that you’ll also be able to master steep inclines and uneven street surfaces with the Sion.

We’re pursuing a single-product strategy with the Sion. For this reason, we will only offer one battery capacity. The Sion will have a battery with a capacity of 35 kWh, giving you a range of 255 kilometers under the WLTP standard per charge.

The Sion will have a range of 255 kilometers under the WLTP standard.

No, we presently don’t foresee an option like this.

Together with our partner ElringKlinger we defined and developed the Sion's battery system. As a next step, we will examine the possibilities for reusing the batteries of our vehicles. We are pursuing the goal of giving our batteries a second life cycle. Ideally, this procedure allows that a battery is not recycled until it has definitely exceeded its lifespan. Car manufacturers are legally obliged to take back batteries and recycle them properly, including Sono Motors. Depending on the structure and material composition of the battery, various methods of recycling can be used. Given that we want to make our entire company as climate- and resource-friendly as possible, we take this issue very seriously and will endeavor to find the most ecological and economically sensible recycling solution possible.

Heat radiation that is beamed from the sun to the earth is mostly absorbed by the earth’s surface. The rest of this heat is then radiated back from the earth. Greenhouse gases, such as CO₂, stop the heat radiated by the earth from being let out into space. This natural process is called the greenhouse effect.

CO₂ is created through human activity, for example through flights, driving cars, manufacturing or burning fossil fuels to produce energy.

The man-made increase in the concentration of greenhouse gases in the atmosphere strengthens the natural greenhouse effect, causing global warming. CO₂ plays a significant role as it makes up most of the greenhouse gas emissions caused by humans.

CO₂-offsetting is an instrument to help protect the global climate: a given amount of CO₂-emissions emitted at one place in the world is prevented at another place, because in the end it is irrelevant for the planet’s atmosphere where on earth greenhouse gases are emitted, reduced or prevented. After mitigating and reducing CO₂-emissions, CO₂-offsets are an effective measure to counteract global warming.

CO₂-offsets work by upgrading and expanding renewable energies and energy-efficient technologies in developing countries to reduce or prevent the emission of gases that affect the climate.

Individuals or businesses seeking to offset their emissions identify and record them, before obtaining ‘certified emission reduction’ (CER) certificates, by making an offset payment to carbon offset providers, climate protection projects or carbon credit dealers. One certificate represents a specific, quantifiable amount (usually one ton) of CO₂ that is saved somewhere. The advantage to this principle is that emissions are saved in the Global South – where it is most economic to do so. There have to be safeguards to check that emissions are reduced on a permanent basis and that the projects are only able to be brought to fruition through the additional funding received through the offset mechanism. That is, if those units or certificates weren’t sold, the projects would be unprofitable and therefore infeasible. The term used in the industry for this core criterion is the ‘additionality’ of the emission reductions.

Various standards are used to certify climate protection projects. They differ in the demands they place on the quality and environmental impact of the project and in local, social aspects. In order to register a climate protection project for certification, there must be scientific evidence of the project preventing CO₂-emissions. Independent bodies examine and certify this preventative effect.

There are further criteria relating to duration and social impact that must be fulfilled on top of those for climate protection benefits. High-quality climate protection projects are characterised by having positive effects for the local population of a project region.

Examples of this can include access to clean energy or improvements in household income or health. The most commonly used certification standards are the Verified Carbon Standard (VCS), Gold Standard and Clean Development Mechanism (CDM), the latter of which was developed by the United Nations (UN). The Gold Standard is seen worldwide as the most rigorous certification standard in regard to the requirements placed on what a project does. Gold Standard climate protection projects must ensure sustainable development in the project countries on top of additionality. The CDM, on the other hand, puts special emphasis on the quality and transparency of processes when registering and realising a climate protection project. The quality of what the project does and how it is organised is usually maximised in conjunction with the Gold Standard.

In June 2017 we decided to offset all emissions emitted at all stages of the supply chain for the Sion manufacturing process. We’re currently busy identifying and recording these emissions systematically. The supply chain of course includes the production and assembly of components and the accompanying logistics, though we also have to consider the emissions from our office and those produced by our business travel. Once we have finished identifying the emissions, we’ll get straight to the final selection of climate protection projects for offsetting, in cooperation with a partner specialised in the area. Our aim is to select projects that satisfy the highest quality standards and generate the greatest possible added benefits for the local population. The community doesn’t have to bear any additional costs for this. In keeping with the way we see ourselves and our goal of protecting the climate, CO₂-offsets are already included in the Sion purchase price.

The Sion is the first series-produced car that can additionally charge its battery using solar power. Integrated solar cells make it possible to use the Sion for multiple days at a time without having to recharge it. In the course of series development, the viSono system was optimized by our team of experts. Full-surface integrated solar cells make it possible to use the Sion for several days without having to recharge it. A total of 248 cells can generate at peak performance up to 1.2 kilowatts. This energy can create electricity for up to 34 kilometers per day during the summer.

Thus, the viSono system enables you to cover the majority of the kilometers driven on average per day using solar energy only. 

For the solar cells, we use monocrystalline silicon cells that are seamlessly integrated into the entire body.

Our top priority is to select the right material. The components we use need to meet these requirements: a service life of at least eight years, resistance to environmental influences such as UV radiation and water, sturdiness and low weight.

Normally, solar cells are laminated into glass with a thickness of 2 - 5 mm. Glass, however, is relatively heavy and isn’t very break-resistant. For this very reason we use a polymer for viSono as a support material. It is light, robust and significantly more break-resistant than glass.

If you experience a minor crash, you should first of all check to see whether and to what extent the cells in the affected panel are damaged. There’s a layer of polymer that provides the solar cells underneath with the best possible protection against impact and damage such as scratches. Unlike glass, polymer is shatterproof and makes our solar modules significantly more durable than traditional panels. Altogether, this means you should check the damaged module to see if it is still functioning and only replace it if it is genuinely in need of replacement.

Thanks to the full-surface integrated solar cells, under optimal conditions, your Sion is able to charge up to 34 kilometers additionally per day through solar power alone. In order to effectively use the hours of sunshine during the day, we are currently planning to enable charging via the viSono system whilst driving as well.

Bidirectional charging means that not only can the Sion be charged with electricity, it can also share its stored electricity any time. As a result, the car can act as an energy storage device on wheels.

The bidirectional charging plug is located in the front at the hood, making it accessible from outside. To use the stored electricity, you can unlock the cover at the hood using your mobile phone or the infotainment system. That way we protect this energy against potential theft.

It’s possible to draw energy from the Sion for any common electronic device (230 volts) with up to 3.7 kW using an ordinary household plug. If that’s not enough, there’s more too. The rapid charging function means you can charge other electric cars with 11 kW or operate high-voltage devices. These days, electricity is usually generated in many areas through two-stroke generators if there is no electrical outlet nearby.

These generators are mostly inefficient and harmful for the environment. The Sion has the ability to replace generators used, for example, on construction sites, at events or in emergency situations. Mobile energy from an environmentally friendly source – that’s the idea behind viSono and biSono.

The Sion has a battery capacity of 35 kWh. Assuming that your household consumes 5 kWh per day, the Sion’s energy will be enough to power your household for 7 days.

Yes, technologically speaking, the Sion is already able to power a household thanks to the integrated biSono system. However, there are a few legal restrictions in this area which we don’t have any influence on. We’re currently taking care of the legal requirements for this.

Merely installing an artificial air filter in the Sion wasn’t enough for us, so we developed the breSono system. We’ve integrated moss into the dashboard and center console to complement the artificial air filter. Moss acts as a natural air filter, meaning that it continuously improves the interior air quality while having a positive influence on the car’s interior humidity. When testing the efficiency of the moss, we found that it filters up to 20 percent of particulate matter out of the air. You don’t even need to take any special care of it. Since the moss no longer has an enzymatic reaction when in this condition, it doesn’t have to be watered, fertilised, trimmed or exposed to sunlight. Whether it’s a hot summer day or the middle of winter, the moss in the Sion will remain how it is. The moss is also easy to replace during a regular filter change. We’ve tested the moss over a period of several years and couldn’t find any noticeable changes. Its colour stays highly consistent and retains its natural appearance throughout the years. Thanks to a special bleaching process, water is extracted and the microstructure that acts as a filter and controls humidity stays as is. This process also protects the moss against discolouration from external influences such as mould or bugs. In essence, breSono has the same properties as a sponge that controls humidity in that it either extracts it from the air or adds it to the air, depending on how moist the air is. If the air is dry, the moss provides extra moisture and its consistency becomes a little bit less soft.

No, the moss has been specially treated so that it’s no longer a living thing. Despite this, it still maintains its positive features for filtering out particulate matter and regulating humidity.

It works in connection with an ordinary air filter and should be replaced at the same time the filter is.

goSono combines three special features of the Sion: powerSharing, rideSharing and carSharing. This functionality allows you to offer other people electricity or a ride over the goSono app or simply rent out your car.

It’s easy to share your Sion with other people thanks to the goSono app. Use it to decide how long you’d like to rent out your Sion for. Other app users will then be able to send you a request and, if you accept it, book your car and unlock it – something made possible through an innovative concept for getting into and out of the Sion. Once your car has been returned, the hire fee will be transferred directly to your bank account.

With the goSono app, you can offer to give other travellers a ride with your Sion. Simply enter where your journey is starting and your destination. You’ll then be able to offer other people a ride along this trip using the goSono app and specify an individual price for the ride. Other users can decide if they’re interested in your offer and want to send a request. Users are notified as soon as you accept their request and you’ll be able to pick them up. The agreed price will be transferred directly to your bank account once you reach your destination. So, whether you’re just commuting or heading to a different city entirely, share your trip, split the costs.

Thanks to bidirectional charging technology (biSono technology), you can use your car as an independent charging station. With the goSono app, you can share your energy with others. If somebody requests access to the power outlet on your car, you can accept or reject that request using your app. Decide easily how much energy you’d like to share and at what price. Other app users will be able to see your offer and the exact location of your car. This function transforms your car into a mobile charging station, which you can even earn money with.

reSono is the Sion’s aftersales service system. It guarantees inexpensive repairs and maintenance by using economical replacement parts. Individual replacement parts for the car will be available to order online at the click of a mouse.

An instructional video and catalogue to back it up will mean that you can install replacement parts in your car without needing much prior knowledge.

If you think it might be a bit too much, you can also simply head to the mechanic and have your Sion repaired there. Our workshop handbook will be available for anyone to view on our website, whether they’re a private individual or business owner. This will help establish an extensive network of independent mechanics, which in turn will guarantee you affordable repair work.

Furthermore, we’re intending to offer select CAD data online free of charge. You’ll be able to print it out for yourself with a 3D printer or at a CNC milling service. This also means that suppliers and manufacturers will be able to order and resell parts without having to purchase special authorisation from Sono Motors GmbH. As a result, spare parts for the Sion can be manufactured quickly and easily, leading to benefits for owners in the form of faster delivery times and lower prices. The only disadvantage to this is that we can’t offer the warranty that is otherwise normally offered by the manufacturer for original parts. In general, however, it’s highly important to us that our parts last a long time as we are genuinely aiming for sustainability.

There’ll be access to reSono on our website as soon as the car is in production and being delivered. You’ll be able to order any replacement part for the car then. For some parts, we’ll also show you alternatives – for example, other places that offer the part in question, which would be the case for normal threaded bolts. In these cases, we’ll tell you if you can also just buy these sorts of parts at your local hardware shop. This way you’ll save time and unnecessary expenses.

During the first stage, you can preorder and make a down payment on a Sion. It comes with a two-week reflection period. In the second stage, in 2020 we will offer you a contract to purchase a Sion. Again, you’ll have a two-week reflection period, during which you can cancel the contract. You have the possibility to pick up your Sion directly at the plant in Trollhättan. Additionally, we are working on an entirely new delivery concept. For an extra charge it will probably be possible to deliver your Sion to your desired location as well.

After making a down payment you’ll automatically be included on the waiting list. Your spot on the list will be confirmed as soon as you have made this down payment. Your preorder is legally a purchase option. This means that you’ll receive a purchase offer for the Sion before delivery commences and you’ll have the option to either purchase the Sion and sign the purchase contract, or opt for a refund of your down payment.

The Sion costs 25,500 euros including German VAT at market launch.

The basic price for the vehicle is 16,000 euros plus the cost of the battery. We’re planning to offer the battery at a one-time purchase price as well as with the option of renting or leasing it. The reason for excluding the battery from the price is that we want to always offer the most up-to-date price. We expect the price to be around 9,500 euros. We will calculate the final price for the battery based on the market rates for battery cells at the time of production.

The following applies to all persons preordering the Sion: you’ll receive a purchase offer for the Sion before delivery commences and you’ll, again, have the option of either purchasing the Sion and signing the contract or opting for a refund of your down payment.

The rights provided under German law for terminating contracts still apply.

Germany’s regular statutory provisions for warranties apply. On top of that, Sono Motors is providing a warranty for the Sion of probably two years or 100,000 kilometers as well as a warranty for the battery of two years, 100,000 kilometers or 2,000 charge cycles.

The first 5,000 preorders were a significant milestone in Sono Motors’ history, for which reason we gave these early adopters a discount. We reached this milestone on June 14 2018. To say thank you to our many fans who didn’t make it in time to preorder a Sion, we extended this discount until June 30 2018. Unfortunately, it’s no longer possible to get a discount on the Sion.

During the first stage, you can preorder and make a down payment on a Sion. It comes with a two-week reflection period. In the second stage, in 2020 we will offer you a contract to purchase a Sion. Again, you’ll have a two-week reflection period, during which you can cancel the contract. You have the possibility to pick up your Sion directly at the plant in Trollhättan. Additionally, we are working on an entirely new delivery concept. For an extra charge it will probably be possible to deliver your Sion to your desired location as well.
