Polestar Polestar 4 (USA)

Brake fluid capacity & service interval

Polestar 4 (USA) models require brake fluid with a capacity range between min and max. The data covers 2 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

TypeSpecifications
Polestar 4 Long Range Dual motor (400 kW) (2024- )
  • Use: Normal
  • Between min and max.
Polestar 4 Long Range Single motor (200 kW) (2024- )
  • Use: Normal
  • Between min and max.

Additional Notes

  • The Polestar 4 (USA) brake fluid specification applies to both the Long Range Single motor (200 kW) and Long Range Dual motor (400 kW) configurations introduced in 2024.
  • Both configurations use a hydraulic brake system, meaning brake fluid is pressurized mechanically to actuate the calipers rather than relying solely on electronic or regenerative braking force.
  • The specified fill level for both configurations is between the minimum and maximum reservoir markers, a range-based standard rather than a fixed volume, which is typical for hydraulic brake system top-ups where exact displacement varies with component wear and fluid condition.
  • The single motor (200 kW) and dual motor (400 kW) variants share the same fill specification, indicating no capacity differentiation between the two powertrain outputs for the brake fluid reservoir.
