Identification
How to tell if your car has it
- Cars badged 60 from 2016–2017 may carry a software-limited 75 kWh pack. Tesla service can confirm.
- The part number on the high-voltage battery label and Tesla service records are definitive. A VIN alone does not encode the cell supplier or pack code.
