BMW iX3 vs Polestar 3: premium pulse for the most technological and refined electric SUV

The premium electric SUV segment is going through one of its most interesting moments. On one side, a German manufacturer with more than a century of history is completely reinventing its most important electric model. On the other, a young but technologically ambitious Nordic brand that has turned Scandinavian minimalism into a selling point. The comparison between the BMW iX3 and the Polestar 3 is, in reality, a duel between two philosophies: the obsessive efficiency of Munich versus the performance hedonism of Gothenburg.

Two philosophies of the premium electric SUV

The new BMW iX3, debuting on the Neue Klasse platform, is the model that opens a new era for the Bavarian brand. Its declared priority is energy efficiency, with an 800-volt architecture, sixth-generation cylindrical cells and a thermal management system designed to squeeze every kilowatt-hour. The Polestar 3, for its part, positions itself as a high-performance SUV coupé, with sophisticated finishes, traceable materials and dynamic tuning developed with the usual rigour of the Swedish house.

We are not talking about identical rivals, but about two visions of what a premium electric SUV should be today: one prioritises real-world range and everyday use, the other driving sensations and visual status.

BMW iX3 xDrive50 from ≈69,900 €: efficiency elevated to an art

The BMW iX3 2025 arrives with the xDrive50 version as its flagship. Its combined output of 470 CV is split between two synchronous motors, propelling the SUV with the brand’s characteristic composure. But the figure that defines the car is not the power, but the 790 km of WLTP range, a groundbreaking value in the segment thanks to the 113.5 kWh battery and meticulously refined aerodynamics.

The interior debuts the Panoramic iDrive, with information projected across the entire base of the windscreen, and a redesigned central screen. Extended level 2+ semi-autonomous driving and bidirectional energy management complete a truly cutting-edge technology package.

Polestar 3 Long Range Performance from ≈104,300 €: performance with a Nordic accent

The Polestar 3 Long Range Dual Motor with Performance pack goes for a different terrain. Its 520 CV place it close to a pure sports car, with all-wheel drive managed by two motors and a chassis with adaptive damping. The result is a SUV coupé with lively responses, precise steering and a visual presence supported by details such as the Thor’s Hammer light signature inherited from its origins.

It is homologated for 560 km of WLTP range, a figure conditioned by its performance focus, its large wheels and the tuning of the Performance pack. The 111 kWh battery is practically comparable to the iX3’s, but consumption is noticeably higher.

Inside, it breathes Scandinavian minimalism: a vertical central screen with native Android Automotive, traceable recycled materials and a Bowers & Wilkins audio system with headrest speakers.

Range and efficiency: the great gap

Here lies the decisive gap. The range of BMW’s electric SUV is clearly superior to that of the Polestar in its Performance version. Although in less extreme versions the difference may be smaller. The comparison between the xDrive50 and the Performance shows each one’s approach: BMW has prioritised kilometres; Polestar has prioritised tenths.

Price and value: just over 40,000 € of difference

The BMW iX3 price starts at approximately 69,900 €, while the Polestar 3 price in Performance configuration starts above 110,300 €. It is a difference that places each one in a different budget league and tilts the rational balance towards Munich. We remind you that these are manufacturer’s recommended RRPs, without offers, dealer discounts, one-off campaigns or aid.

Comparison table: which premium electric SUV to buy

Verdict: the best premium electric SUV for Spain

As the best premium electric SUV from a rational standpoint, the BMW iX3 emphatically dominates this premium electric SUV comparison: more range, better efficiency and a much more restrained price. The Polestar 3 justifies its premium if you value design, pure performance and a distinctive aesthetic identity that no German rival offers today.
