Its a nice idea which probably has a lot of complex implications. It would probably be a huge pain to figure out dimensions and compatible electric motors for every brand of non-electric vehicle, so the production of replacements would become very wide. Typically, the battery of an EV isn’t just a brick in the engine room, but it’s a whole range of cells along the length of the vehicle. Using the same space as the combustion engine might leave you with a vehicle with terrible range. Also, the safety of a car takes the engine into account. Replacing a combustion engine with an electrical engine would likely require a whole new safety overview for each individual model.
I honestly really hope that your suggestion would work, but I’m not expecting to see this becoming a wide solution before EVs dominate the market anyway.
I don’t think he meant to literally take the ice out of a camera and replace it with a motor and battery.
But rather he meant, make a new ev, on an EV chassis, but without all the nonsense that drives up costs without adding significant value.
I don’t need touch screen everything with 3d gaming built in, gull wing doors, and custom flush door handles that don’t work if you have a hand injury or any type of disability.
