In this video, we are putting the resistive heater of the Legacy Tesla Model 3 against the heat pump of the 2024 Model 3, commonly known as the Highland.

This test aims to determine which of the two will warm its cabin to 24°C (or 75°F) faster while remaining in one place and how much energy each requires to reach that temperature.

We tracked the data via the BMS, using our OBD Commander, and the readings were displayed in our S3XY App.
