Sono Motors unveiled this week the final production design of the Sion EV, a solar electric vehicle that’s been in the making since the Munich-based startup launched in 2016.
It’s been a long and bumpy road for Sono Motors, a journey that involved a couple of crowdfunding campaigns, a near insolvency and a debut on the Nasdaq exchange as a publicly traded company.
The solar-powered fruits of those rather tumultuous labors were shown off at its bustling “Celebrate the Sun” Community event. The Sion solar-powered EV took center stage. However, another product called the Solar Bus Kit, a series of solar panels that are designed to be retrofitted onto 12-meter public buses, suggests the company has more ambitious plans beyond one passenger vehicle.
The question, of course, is can Sono Motors produce and sell the EV at volume? And how?
Sono aims to begin deliveries of the Sion in the second half of 2023 to customers in Germany, Austria and Switzerland. The company did not provide guidance on how many Sions would be delivered next year. The only metric it has shared is that it expects to make 43,000 Sions per year with a production capacity of 257,000 over seven years, according to a company spokesperson.
However, even the most well-funded EV startups have had trouble making it to production recently. Sono has had to combat a range of challenges since going public in November last year, from a plummeting stock price to switching manufacturing partners, and its path forward to production and delivery will likely continue to be bumpy given current market and supply chain uncertainty.
Let’s break down what this company is up to:
The Sion’s final production design

The Sion is a compact, five-door, family-friendly hatchback that will sell for €25,126 (~$25,628 at today’s conversion). Its outer shell will consist of 456 integrated solar half-cells that will collect power from the sun and enable self-sufficiency on shorter journeys. Of course, the vehicle will still use a traditional charger to refuel, but the constant drip feed of solar should be enough to take care of most urban commutes, the company says.
The car’s 54 kWh lithium iron phosphate battery has a range of about 190 miles. Sono expects the energy generated by the solar cells to extend that by an average of 70 miles, and up to 152 miles, each week. In addition, the Sion is built with bidirectional charging technology, which allows commuters to use energy stored in the battery (~11 kW) to power homes or other electronic devices.
