One of the biggest differences between Polestar 2 model years is the cabin heating system. Early cars relied solely on a PTC (Positive Temperature Coefficient) resistive heater. The heat pump was introduced as an option in 2022 (bundled with the Plus Pack), and is standard on all US cars from model year 2025. This has major implications for cold-weather range.
PTC Heater (2021, and 2022 without Plus Pack)
The PTC heater works like a large electric space heater. It converts electrical energy directly into heat. It's simple and effective, but it draws heavily from the main battery — typically 3–5 kW in cold weather.
Impact: Expect 20–35% range loss in sub-freezing temperatures, depending on how cold it is and how aggressively you heat the cabin.
Heat Pump (2022+ with Plus Pack, standard on US cars from 2025)
The heat pump works like an air conditioner in reverse, extracting heat from the outside air (even when cold) and moving it inside. It's significantly more efficient — roughly 2–3x the heating output per kW of electricity consumed.
Impact: Winter range loss is typically reduced to 10–20% in the same conditions.
Can I Retrofit a Heat Pump?
Unfortunately, no. The heat pump requires different plumbing, a different compressor, and integration with the thermal management system. It's not a bolt-on upgrade.
Tips for Maximizing Winter Range
- Precondition while plugged in. Heating the cabin and battery while connected to a charger means you start with a warm car and full range.
- Use heated seats and steering wheel over cabin heating — they're far more efficient.
- Lower your cabin temp by 1–2°C. The difference in comfort is minimal, but the energy savings add up.
- Plan charging stops conservatively in winter — your real-world range will be lower than the estimate suggests.
