BERLIN – A Munich-based startup has taken advantage of the strong Bavarian sun this summer to test the final development of the charging system of its Sion car, an all-electric solar vehicle that lets you charge as you drive.

Germany will likely miss its target of putting 1 million electric cars on the road by 2020 but the government said in April it was ready to offer support to companies that make batteries for electric vehicles.

Sono Motors, founded in 2016, is developing the Sion, a fully electric vehicle that has solar cells integrated into its bodywork. It can be charged via solar power, from conventional power outlets or other electric cars.

Production will start in the second half of 2019 at one of its German plants and the company has around 5,000 orders, which it aims to start selling at $18,540 next year.

Sion will have 330 solar cells attached to the vehicle’s roof, hood and sides, and its battery system will offer a range of around 155 miles before it needs recharging.

“We have a seat heater, there is air conditioning, there is a large infotainment system where I can also connect my phone interactively, which means I really have a full vehicle which is very simple, has no frills,” Laurin Hahn, co-founder and chief executive of the startup, told Reuters.
