Equipment few rivals have, on either carShowHide
Drivetrain
The BMW X3 uses a Petrol producing 140kW and 310Nm of torque, sent through a auto to a AWD layout. It covers the 0-100km/h sprint in 8.5 seconds.
The Polestar 4 responds with a Electric Motor making 200kW and 343Nm, paired to a single-speed fixed gear driving the rear wheels. It gets to 100km/h in 7.1 seconds.
The Polestar 4 has the clear power advantage at 200kW vs 140kW. In the 0-100 sprint (manufacturer-claimed), the Polestar 4 is 1.4s quicker. For most buyers, the way each car feels day-to-day matters more than outright acceleration.
Space & Comfort
The BMW X3 measures 4,755mm long on a 2,865mm wheelbase, 85mm shorter than the Polestar 4 at 4,840mm (2,999mm wheelbase). The longer wheelbase on the Polestar 4 generally means more rear legroom.
Boot space is 570L in the BMW X3 and 526L in the Polestar 4, giving the BMW X3 a 44L advantage.
For towing, the BMW X3 leads with a 2,400kg braked capacity vs 1,500kg. That 900kg difference matters if you regularly hitch up.
Neither U-turns in one sweep on a 7 m local street (both need a three-point turn); the Polestar 4's turning circle is 0.5 m tighter, 11.6 m against 12.1 m kerb to kerb. The street estimate is indicative, worked from the published turning circles.
Cost to own
At 15,000 km a year, fuel for the BMW X3 costs about $2,138 a year (7.5 L/100km) and electricity for the Polestar 4 about $806 a year (16.8 kWh/100km), at $1.90 a litre and 32c a kWh.
Warranty: 5 years / Unlimited (BMW X3) and 5 years / Unlimited (Polestar 4).
Where each one leads
The BMW X3: the bigger boot with the seats up (570L against 526L) and the higher braked towing limit (2,400kg against 1,500kg).
The Polestar 4: the lower starting price ($78,500 against $86,100) and more power (200kW against 140kW).
The Verdict
Polestar 4 scores higher, 75 vs 73
The Polestar 4 scores 75 to the BMW X3's 73 on the CarSorted Score, and leads 3 of the 5 spec rows that separate them, at the lower price. The biggest gaps: practicality (BMW X3 ahead by 11 points), performance (Polestar 4 ahead by 10 points). Boot space with the seats up: 570L in the BMW X3, 526L in the Polestar 4.

How to read this page. Prices, specifications, ANCAP ratings, warranty, the CarSorted Score and the verdict come from our records for the grades shown, sourced from the manufacturers' Australian documents, and change when those records change; the date each was last checked is printed under the headline. Prices are recommended retail prices before on-road costs unless marked drive-away. A plug-in hybrid's fuel figure is labelled with its basis: with a full battery (the certified combined figure) or as a hybrid (battery depleted). Charging and running costs are estimates on the stated assumptions. Always confirm price and specification with the manufacturer or dealer before you buy.
