Another EV startup near me, Bollinger is going pretty much the opposite direction from Aptera: A class-3 heavy truck (18,001lbs GVWR), pure EV with kilowatt-plus power-export for jobsite and field use. No solar roof, which is a shame, because they could probably add 1 or 2 whole miles of range per day! ;)
There's an SUV and a pickup in the works, plus stripped chassis options for body-builders: https://bollingermotors.com/
I love that both the B1 and the Aptera exist, because the duality speaks to everything I love about EVs. The technology is so versatile you can make it fit any need, and the tooling costs can be low enough that upstarts can enter the market and disrupt things. That's the hope, anyway.
(Really though, I love the no-frills aesthetic with conventional controls and knobs for everything. I'd kill for a screen-delete option in the Aptera, just give me a double-DIN hole to mount a stereo and I'll cook up my own HVAC controls that spit out CAN messages. I work in infotainment/ADAS testing, and the more I've had to interact with touchscreens in cars, the more I've come to utterly loathe them.)
So given that the Aptera is slated to have a power-export inverter as well, it's possible that either of these vehicles could L1-charge the other. Which would look pretty absurd, if you passed such a scene at the side of the road.
