This car is not available for sale through Tesla.com. It can be ordered by phone or directly at a Tesla Store. The battery is the same as the Standard Plus model but with the battery pack software-limited to 45 kwh instead of 50 kwh. This means that it has the 50 kwh battery but only 45 kwh can be used. It is possible for the buyer to pay Tesla at a later point in time to get the full 50 kwh present in the battery.
