The Polestar 4 carries 94 kWh usable from a 100 kWh pack — among the largest batteries sold in Australia. Combined with Polestar's warranty, which explicitly names State of Health and a 70% floor over 8 years or 160,000 km, it is one of the more straightforward used EV propositions to assess.
The pack
| Variant | Years | Usable kWh | Claimed range | Real-world consumption |
|---|---|---|---|---|
| Long Range Single Motor | 2024–2026 | 94.0 (100.0 gross) | 620 km | 19.0 kWh/100km — modelled |
94 kWh at a modelled 19.0 kWh/100 km is roughly 495 km real-world against a 620 km claim. It is not an efficient car — it is a big, heavy, fast one — but the pack is large enough that the real-world figure is still strong.
Why a big pack absorbs degradation better
This is the practical argument for buying a long-range car used, and it is worth understanding properly.
A 10% capacity loss on a 94 kWh pack removes about 9.4 kWh — roughly 49 km of real-world range, leaving around 446 km. The same 10% on a 45 kWh city car removes 4.5 kWh, which sounds better until you notice the car only had 240 km to begin with.
Big packs do not degrade more slowly. They just have more room to lose it in, and that is what determines whether the loss changes how you use the car.
Warranty position
8 years or 160,000 km, 70% State of Health floor, applying regardless of a change in ownership. Polestar is one of very few manufacturers to write the guarantee in the exact language a buyer cares about. Full terms: Polestar battery warranty in Australia.
What to check before you buy
Measured State of Health against the 70% floor, and cell voltage spread
In-service date and odometer against 8 years and 160,000 km
DC fast-charge history — a car this size gets fast-charged often
Whether it was used commercially, which is common on large premium EVs
