Sono Motors reveals final design of its solar-charging Sion EV

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-power 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.

Other enhancements to the final design’s exterior and interior includes a sleeker, cleaner-looking vehicle, according to Sono.

The exterior has new headlights, including a new daylight strip, rear lights, a rear camera, a bottom sideline design and a revamped charging lid in front. There are also new door handles, which photos show have the words “made to be shared”  — a nod to Sono’s hope to get this car into fleets.

Sono says paid reservations have increased from 13,000 last November to more than 19,000. That could mean a net sales volume of €415 million if all reservations result in sales. With an average down payment of €2,225, Sono could have over €42 million in the bank to help it get to production.

(By the way, if those numbers — 19,000 x €25,126 — don’t quite add up, it’s because the price of the Sion has shifted over time and earlier backers are grandfathered into their original prices, says a company spokesperson.)

To bring costs down, Sono Motors has relied on outsourcing its vehicle’s manufacture and distribution. Previously, Sono planned to partner with NEVS, the Swedish EV manufacturer that acquired the assets of the bankrupt Saab Automobile in 2012. But NEVS’s parent firm, Evergrande, is deep in debt and is still trying to sell NEVS, which is still struggling to put its Saab 9-3 into production.

Sono switched gears in April and signed a contract with a new partner, Valmet Automotive, which manufactures in Finland.

The solar bus kit

While Sono’s solar bus kit can’t turn a diesel-pumping bus into an eco-friendly hybrid, it can take some of the emissions out of the equation.

The kit, which has been standardized to work with “virtually all European bus fleets,” can save up to 1,500 liters of diesel and up to 4 tons of CO2 per bus per year, according to the company. Its total size of about 8 square-meters of solar panels provide around 1.4 kW at peak installation. That solar energy can be used to power a bus’ subsystems such as HVAC.

Sono said bus fleet operators stand to see a potential payback time of about three to four years, depending on the sunniness of days in operation and fuel prices.

At CES 2021, Sono said it would license its solar body panel technology to other companies as an additional source of revenue, and this new bus kit is a part of that move to diversify the business.

Since going public, Sono says it has ongoing letters of intent, pilots and prototypes for 19 companies that are implementing the company’s solar technology on a variety of vehicle architectures, like buses, trailers, trucks and electric transporters.  For example, Sono recently piloted a solar bus trailer in Munich to provide backup power for public transport. Sono has also partnered with the Reefer Group, a manufacturer of refrigerated semi-trailers, to build a solar trailer for testing.

The company said its B2B solar business is already generating revenue, more details on which will be shared during the company’s earnings call in September. Sono’s stock has plummeted since its debut, losing close to 93% of its value, so the company will definitely need to earn another source of revenue as it revs up for production next year.

Why Sono stock has taken a hit

When Sono Group, the parent company of Sono Motors, began trading, it opened at $20.06 after the IPO was initially priced at $15. Shares hit a high of $38.74 before the market closed on its first day. At the time of this writing, Sono Group is trading at $2.64, a slide that has continued even after the company revealed the production version of the Sion.

It seems the buzz around EV startups has started to fizzle.

In May, Sono closed its previously announced underwritten follow-on offering of 10 million ordinary shares, with an additional 1.5 million shares available for the underwriters — which include Cantor Fitzgerald and B. Riley Securities — at an even greater discount.

Sono said it gained $40 million in gross proceeds from this offering, which it used to help fund the start of production of its Sion, but investors are likely to see the offering as one that devalues shares to an even greater extent.
