Is this a reading comprehension failure?

I said 5-10% of their ideal output. Not that 5-10% was their ideal efficiency. I'm sure they can do fine assumed directly at the sun, but those aren't getting anything close to that. Ever. Under any circumstances. I'll stand behind my overall estimate of 5-10% of ideal.

Hell, even if you get them exactly perpendicular to the sun in the late afternoon, they'll only be getting within 25-30 degrees of the sun. And it'll be late afternoon so solar energy will be reduced already. And... Aiming one side at the sun means the other side it's totally shaded! Max 50% off the top without el anything else right there.

Nope. Side panels = dumb dumb dumb.

It is a German car.
At Northern European latitudes, mornings and evenings are long and the sun is only above 45 degrees for a few hours in the late spring and early summer.
Even in Germany a flat orientation is more efficient than a vertical one, but the difference is not as large as it would be closer to the equator.
The space is available, so if the weight is low - why not? It could easily add a few miles of range.

Agreed. I have found that panels laid on a flat vehicle roof produce around half of name plate rated power. Even in sunny New Mexico.
Since I have actually put panels on top of a vehicle and tracked their output, I know this.

Interesting.

750kg tow rating, and a terrarium in the dashboard.

Any color but black and the solar panels are very obvious.

It sounds great, but it's too good to be true. There's no way a carbon fiber structure, solar-powered BEV will come in at $18,000.

But I still want one.

Producing parts is cheap. Like fiberglass boats but wierder. Tooling & ovens to make many parts fast & accurate is $$$$$$$. I can see $30,000

Unless they had some large-volume fleet orders that could speed up the ROI on the equipments meant to make the carbon-fiber structure, $18000 doesn't sound realistic.
