2026 Polestar 3 Design Preview

Polestar, the Swedish electric performance car brand, makes extensive hardware upgrades to its flagship SUV, Polestar 3, for the 2026 model year. Overall performance improves significantly thanks to a new 800 Volt electrical architecture with substantial increase in power, faster charging, and greater core computer processing power.

The 2026 model year marks a major technological leap for Polestar 3 and its SPA2 platform with the introduction of an 800 Volt electrical architecture. This upgrade enables significantly faster DC charging with a peak rate of up to 350 kW, meaning that the 10–80% battery charge benchmark can take as little as 22 minutes, which is more than 25% faster than before.
The new architecture also brings enhanced efficiency, up to 6% according to the WLTP cycle, and supports the integration of new lithium-ion batteries from supplier CATL: a 92 kWh battery pack for the Rear motor version and a 106 kWh battery pack for the Dual motor and Performance variants. Combined, the faster DC charging and increased efficiency further improve the already capable long-distance driving abilities of the Polestar 3.
