Idk, even if you made almost everything out of aluminum , thats like $2000 for the raw metal for the frame and body, 8k for a 80kwh battery, about 5.5k for a 166HP emrax 228 motor off the shelf… with no transmission, the most expensive components combined are less than 20k. I dont see how even a 35k EV would not be profitable with some sensible off the shelf components.
