Lightyear One - from solar racer to commercial product

Students from the Technical University Eindhoven have built a line of family class solar racers called Stella.
Only recently they presented its last incarnation, the Stella Vie.
They won the World Solar Challenge Cruiser Class twice.

As the goal is to build cars that can be practically used, and are road legal for that matter, many wonder what it would be like to actually own one.
But there were no plans to sell them to the public.

That may change soon.
A group of ex-students of the TUE who were part of Solar Team Eindhoven have formed a company named Lightyear.

A few shots of their Lightyear One virtual prototype:



It has a battery range of 400 to 800 km, depending on battery pack options.



The solar cells cover the entire roof and back.



It won't be cheap: "Starting from 119,000 excluding taxes."

If it is (nearly) self-powered, then it will cost a lot, yes. But the design looks very good indeed, so maybe a regular BEV version with PV panels for your house would be reasonable?

I think they first need to learn how to create actual images of their car, rather than a few red & white streaks on a black background.

Then they need some basic math to figure out that those solar cells aren't going to produce enough power to run the car.

You read anything about who they are and why they think it will work, no?

Sticking 2 square meter worth of 23% efficiency solar cells on a standard BEV is not going to result in a practical charge-free car. If you cover a Tesla with solar cells you get about 2000 free miles per year, tops. It is not worth it.

So they will use a design not unlike the solar racers, with expensive solar cells, batteries with extreme power to weight ratio and lost of super light materials; they expect to keep the weight well below one metric tonne.

But most of all it needs to be a practical car, more than the Stella racecars are. You can get the groceries in those, or do a weekend trip with the family, but they are compromised by the race design. Still, the Stella Vie is not that bad looking.
If the Lightyear One can retain half the efficiency of Stella Vie then they will easily match their aim.

It's called "Burlesque Marketing," borrowed from the oldest profession, tease'em with just enough of a glimpse to get them interested (pasties not included).
