The Sono Sion all-electric six-seater has been revealed, ahead of first deliveries in two years’ time.
The entry-level Sion Urban costs €12,000 (£10,800) and has a range of up to 74 miles, while the €16,000 (£14,400) Sion Extender features a 30kWh battery pack and a range of up to 155 miles.
Both variants six-seat configurations, with two rows of three seats, and are capable of being charged by solar energy, via 7.5 square metres of solar panels.
Interior details are limited, but a 10in infotainment screen dominates the dashboard and connects to smartphones via Bluetooth or wi-fi. More unusually, the Sion does without conventional pollen filters for the interior, instead using a strain of moss to filter and purify the air entering the cabin. Sono says the moss also reduces noise entering the cabin and is fire repellent.
The crowdfunding will enable Sono to produce a series of working prototypes, which customers will be able to test drive at the start of 2017. The company hopes to raise €150,000 (£135,000) to do this, with initial investors in line to receive the first Sion examples providing adequate funds can be raised.
