today Electric cars are expensive, not a real solution in terms of the environment and also dependent on a charging infrastructure that is still not in sight. The Munich start-up Sono Motors wants to counteract these disadvantages with the E-Mobil Sion. The Stromer, which is still under development, should only cost 12.000 euros and supply itself with electricity.
The little van looks a little quirky with its outer skin paved with many solar cells. Although not haute couture, the shape allows for a generously dimensioned interior, while the solar cells can generate a lot of electricity. The Sion's sunlight collectors are said to cover an area of 7,5 square meters and achieve an efficiency of 22 percent. Sono Motors calculates that electricity can be generated from this every day for a range of around 30 kilometers - even while driving. Since on average a car is only driven 22 kilometers a day, according to Sono Motors, the Sion could theoretically be used autonomously by infrastructure and energy suppliers and even drive CO2-neutral.
Either a 14,4 kWh or a 30 kWh battery is to be offered as the power storage, which allows ranges of 120 or 250 kilometers respectively. Long journeys would also be conceivable, because in the fast charge mode it should be possible to fill the lithium-ion batteries up to 80% in just a few minutes. The 4,11 meter long six-seater is powered by a 50 kW / 68 hp three-phase asynchronous motor, which should enable a top speed of 140 km / h.
The start-up Sono Motors is currently working on a prototype, while the crowdfunding platform idiegogo is being used to promote supporters of the project. At the beginning of 2017, these should also be given the opportunity for first test drives.
However, Sono Motors does not have a concrete plan for series production. The makers don't want to set up their own production site anyway. The idea is rather that the Sion can be assembled from individual parts from suppliers or car manufacturers.
In terms of price, the decentrally produced basic vehicle could then be had for as little as EUR 12.000. However, this calculation does not include a battery, which would then have to be purchased or rented.
