history

The founders of Sono Motors have been working on realizing the Sono Sion since 2012. In 2016, 2017 and 2018, around 10 million euros were collected for implementation as part of three crowdfunding campaigns. In addition, several medium-sized investors joined Sono Motors in 2017, including the founder of the energy service provider Juwi and the Böllinger Group.

Computer graphics of the vehicle were presented in July 2016. The vehicle should be produced by a contract manufacturer not named. By August 2017, Roding Automobile had built two functional prototypes that were not approved for use in public transport and whose shape and function were to be largely similar to the end product. In the years 2017 to 2019, these vehicles could be test-driven by interested parties on presentation tours through Germany, Austria, Switzerland, Italy, the Netherlands and Sweden. The experiences and wishes gained in the process flowed into further development. As a result, the project, which was presented in March 2019 as a near-series production, deviates significantly from the functional prototypes, both in terms of its external shape and its technical (drive).

According to Sono, series development began in autumn 2017 in cooperation with various partners. The crash test or homologation should take place in 2019, with the aim of achieving the 4-star NCAP safety standard . Series production and delivery of the Sion should begin in 2019.

On May 9, 2018, Sono Motors announced the award of an order for the development and manufacture of the battery system for its vehicle to the German automotive supplier ElringKlinger . The total volume amounts to several hundred million euros over a term of eight years. Six months later, interested parties learned that the purchase price of the battery would be 9500 euros instead of the previously forecast 4000 euros. On June 6, 2018, Sono Motors announced that the Sion would be equipped with LED headlights, which was considered unusual in this price range. Automotive Solutions Germany GmbH (ASG) was named as the supplier.

On June 14, 2018, according to a press release from Sono Motors, the targeted minimum number of 5,000 reservations for the Sion was reached, and the start of production for the second half of 2019 was announced. This was no longer realistic when Sono Motors presented the series design of the Sion on March 4, 2019.

Finally, on April 17, 2019, it was announced that National Electric Vehicle Sweden (NEVS) would start production in the middle / end of 2020 at the Trollhättan (Sweden) site in the former factory of the vehicle manufacturer Saab .

In May 2019 the number of 10,000 reservations was reached, in January 2020 there were 13,000.

On December 1, 2019, Sono Motors announced on its website that 50 million euros would be needed to continue the project by the end of the same month. To this end, the entrepreneurs again called for a crowdfunding campaign. A further 205 million euros would then be required for vehicle production. If the financing is successful, production could start in September 2021. After the deadline was extended, the crowd funding target of 50 million euros was achieved on January 18, 2020. According to information on the website (as of June 2020), the actual incoming payments generated by the campaign amount to approx. 36.6 million euros. Of this, around 15 million euros will be used to manufacture four near-series prototypes and to prepare for series production.

model

The Sono Sion is a purely electrically powered car which , in addition to being charged via a type 2 / CCS charging interface, is also charged by the solar modules integrated into the outer skin of the body .

drive

Sono Motors uses a three-phase asynchronous motor with an output of 80 kW (109 PS) as the drive in the prototypes .

A three-phase synchronous motor with a maximum output of 120 kW (163 hp) will serve as the drive for the series . This is supplied by Continental together with the transmission and electronics .

The motor voltage is 400 V. In the current prototype, the power is transmitted to the rear axle via a single gearbox. According to the company, the series type should have a front-wheel drive. The top speed is limited to 140 km / h.

Solar cells ( viSono )

The roof, the bonnet and large parts of the outer skin of the body are equipped with monocrystalline silicon cells (particularly efficient in diffuse light, among other things, they should still achieve 100% of their yield at angles of incidence down to 70 ), which are protected by a layer of polymer. The start-up uses the product name viSono for this . A total of 248 photovoltaic cells are to be integrated into the body. The maximum total power specified by the manufacturer is 1200  W p , which should increase the range under favorable conditions (sunshine) in Central Europe by around 34 km per day and an average of 10 km per day over a year.

Furnishing

Sion Motors pursues a one-product strategy, i. H. the car is expected to be produced in only one trim level.

The Sono Sion offers space for five passengers. The seats offer 45 cm shoulder room, the driver's seat is adjustable in height and position. Initially, only black will be offered as the exterior color. The trunk has a standard capacity of 650 liters and can be increased to a total of 1250 liters by folding down the rear seats. In the interior, a natural filter made of moss regulates the humidity and filters fine dust ( breSono ). The passenger airbag can be switched off so that a child seat can be placed there. The electric handbrake is integrated in the center console. A detachable towbar for trailers weighing up to 750 kg should be available as an option.

The Sono Sion is to be equipped with ABS , an alarm system, driver and (deactivatable) passenger airbags, and ESP with traction control. The infotainment system with Bluetooth will have a 10-inch touchscreen with smartphone connection in the form of Android Auto and Apple CarPlay . A 17.8 cm (7 inch) display in the steering wheel area should provide information.

Battery and range

A water-cooled lithium-ion accumulator (LiMn 2 O 4 ) with a capacity of 35 kWh and a mass of around 250 kg is to be used as the drive battery . The production of the drive battery packs will be taken over by the German supplier ElringKlinger, the battery cells come from a joint venture between ElringKlinger and CITC in China. ElringKlinger has a fully automated production line so that the drive battery can be produced cost-effectively. Because of the hoped-for developments in battery technology, a specific model should only be specified in the later development process.

The Sono Sion should have a range according to NEDC of 320 km; that would correspond to approx. 250 km under realistic conditions. The WLTP range is specified as 255 km. The solar cells should be able to provide a range of up to 30 km per day.

Load capacity

The Sono Sion is to be delivered with a combined charging system plug system that enables fast charging with direct current when traveling, with a charging power of 50 kW being specified. The IEC-62196 type 2 connector designed for three-phase current is integrated in the CCS ; the associated type 2 charging cable is expected to be included at an additional cost. The integrated charger should make it possible to charge the battery at home, at work or at three-phase charging stations using mode 2 and mode 3 charging processes in accordance with IEC 62196 with an output of 3.7 kW to 11 kW.

Use as electricity storage ( biSono )

A current delivery option known as a bidirectional charging system is intended to enable other electric vehicles with up to 11 kW to be charged on the Sion via a type 2 socket. The integrated stand-alone inverter also allows the operation / charging of common household appliances (3.7 kW / 230 V) via a Schuko socket. Sono Motors is striving to feed back into the power grid ( vehicle to grid ).

Workshop concept ( reSono )

The workshop book for the Sion including the CAD data for non-safety-relevant spare parts for 3D printers or CNC milling should be publicly accessible (license-free) with the delivery of the first models, so that cheap repair costs can be expected. With additional explanatory videos and a catalog of instructions on the website, you should be able to install spare parts in the vehicle independently or have them installed by a workshop without much prior knowledge.

Sharing ( goSono ) with a mobile phone app

If desired, vehicle owners should be able to offer other people electricity (power sharing) or a ride ( ride sharing ) or rent out their car ( car sharing ) using their own smartphone app .

Reservation and order

The vehicle can currently be reserved on the Sono Motors website against a deposit. There is a two-week right of revocation and withdrawal for the advance reservation. While earlier reservation in the older terms and conditions (as of January 31, 2018) was guaranteed a purchase contract until December 31, 2019 under §8, in the current terms and conditions (as of April 17, 2019) §8.3 a withdrawal from the reservation is granted if no purchase agreement was offered until December 31, 2020. According to the company website (as of early 2020), interested parties should be offered a purchase contract for the Sion in 2021. The delivery should initially only take place free of charge to Bremerhaven , for an additional charge also to a desired location. From 2021, customers should also be able to pick up their vehicles directly from the NEVS factory premises in Trollhättan. In the meantime (since May 2019) more than 10,000 pieces have been pre-ordered.

Prices

The Sono Sion will cost 16,000 euros in its standard configuration without a battery. The low price compared to other electric cars may be. a. achieved through the use of older - and therefore no longer legally protected - components from traditional car manufacturers. The drive train and the battery are purchased from automotive suppliers.

The battery should be offered for a monthly fee (rent or leasing) or a one-time purchase from the time the vehicle is purchased. The purchase price of the battery is forecast by Sono Motors at 9500 euros, originally it was 4000 euros.

Guarantee services

Sono Motors plans a warranty for the vehicle of two years or 100,000 km, and for the batteries a warranty of two years, 100,000 kilometers or 2,000 charging cycles.
