Owners of the Tesla 60kWh version of its Model S and Model X actually have the same battery as the 75kWh vehicles but the battery has been purposely limited or “damaged” to provide only 60KWh of mileage. Is is really less expensive for Tesla to build more expensive batteries for all cars (including the lesser version) than to create and keep two inventories of car batteries? Probably.
