Early models of new drive trains and chassis are always more expensive to absorb the cost of retooling factories, regulatory compliance, and NREs involved in the development. Combine that with uncertainty (no one knows the real demand of EVs, since they aren't mass marketer yet) and you have a recipe for "expensive."

It's impossible to ignore the supply chain problems as there were not EVs available prior to 2021/2022 from most manufacturers.
