What sets a red flag for me is the phrase "based on." That could mean anything from using the actual Aptera design inside and out, to building an entirely new vehicle that generally resembles the Aptera in shape. There's been a lot of anticipation over the Aptera, and a lot of people had high emotional investment in their reservations. Zap could capitalize on that just with the name and the shape. But to think they could bring out a quality vehicle in just a year might be a stretch. And a three-wheeled car will be classed as a motorcycle and will not require safety testing. The stock Xebra would not go over 35 mph. Its slow speed was its major safety feature. I would never go on the freeway in a car that had not been safety tested, and given Zap's history, I'll be surprised if they voluntarily do safety testing when it's not required.The new Aptera vehicle is said to be based on the design that participated in the Progressive Automotive X-Prize, known internally as the SO-1.
As I said, I loved my little Zap Xebra and will not discount Zap out of hand. However, I'd approach anything from Zap with extreme caution.
That said, I hope they can do this, and that the new car is everything the Aptera was supposed to be. More EV choices is a good thing.
