New 800 Volt Polestar 3 - faster charging, more power, and increased intelligence

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.
