Two electric cars go head to head. Which EV is the better buy for Australian drivers in 2026?
Specifications and pricing correct at time of publishing. Prices are RRP before on-road costs unless stated otherwise. Always confirm with the manufacturer or dealer before purchasing.
Price Breakdown
The Polestar 4 starts from $78,500 before on-road costs, while the BMW i4 opens at $88,900. That makes the Polestar 4 the more affordable entry point by $10,400.
Once you factor in stamp duty, registration, CTP insurance, and dealer delivery, expect to add roughly 8-12% on top of the RRP depending on your state. That puts estimated driveaway prices in the ballpark of $86,350 and $97,790 respectively.
