- fewer number of parts
- faster manufacturing since IC engine has a lot more parts
- Battery manufacturing has been a while now (EVs still same cells as other applications)
- In general, much lower BOM (Bill of Material)
- granted, Software is more advanced but if we take Tesla out of picture, rest of the EV companies, have standard software
- Is due to economies of scale problem?
Please ignore current supply chain shortage issues as that is temporary (hopefully) and EV's were expensive prior to covid as well
I _suspect_ it's two things:
Firstly, as you suggest, is a lack of economies of scale, startup expenses, high R&D costs, etc. Existing car companies can do a lot of the EV manufacturing with known techniques, existing machinery, etc.
But secondly, at least Telsa has an absurdly high profit margin compared with traditional high-volume models. They're taking the luxury route of a smaller sales volume, higher per-unit costs, and making a good profit off each vehicle.
In short .. because they can.
