    Sandy Munro did make a mention of active suspension with regards to the Aptera as a means of dealing with any instability. It sounded more like a suggestion rather than an existing design goal. It’s highly unlikely that they would attempt it right out the chute, they need to get a car out the door as soon as possible and that mean using a conventional suspension.

    Decades ago Bose developed an electronic suspension for cars, it could drive over a log without you feeling it. They got no interest from any auto maker so they dropped it. I expect the costs at the time would have made it a non-starter. But in an EV it would make sense. With an active suspension you can recover the energy used to absorb bumps in the same way as regenerative braking recovers the energy used to decelerate the car. Shock absorbers are dissipating energy as heat, I wonder if that’s a significant amount of energy that’s lost.
