- Brembo’s 50-year motorsport legacy shapes Polestar 4’s braking system.
- Performance Pack features ventilated discs and four-piston aluminum calipers.
- Integrated regenerative braking boosts range up to 590 km (WLTP).
- Partnership delivers precision, confidence, and design synergy.
At Brembo’s R&D facility in northern Italy, braking isn’t viewed as the end of performance—it’s where it begins. Matteo Rampazzo, Brembo’s Market Director, explains how decades of motorsport experience have influenced the braking system engineered for the Polestar 4 Performance Pack.
Motorsport Heritage Meets Modern EV Precision
Brembo has spent more than five decades perfecting the art of braking. The company’s systems are trusted across top-tier motorsport disciplines, where precision and reliability determine victory. That same expertise now underpins Polestar’s most dynamic electric vehicle.
“Braking is where speed really begins,” says Rampazzo. “True performance isn’t only how fast you go—it’s how confidently you can stop.”
Engineering Confidence Into Every Stop
Each Polestar 4 Performance Pack is equipped with:
- Ventilated brake discs: 392 × 34 mm (front) and 364 × 26 mm (rear)
- Lightweight aluminum four-piston calipers: Delivering consistent pressure and reduced fade
- Optimized weight balance: Improving vehicle dynamics and efficiency
- Low dust and wear design: Enhancing longevity and maintaining clean aesthetics
The system’s thermal stability ensures performance even under high load or repeated hard braking—vital in performance EVs where heat management is critical.
Smart Braking for Extended Range
“A great braking system doesn’t just stop fast—it stops smart,” Rampazzo notes. Brembo’s integration with Polestar’s regenerative system converts kinetic energy into usable power, extending driving range. In the Polestar 4, this synergy helps deliver a WLTP-estimated range of 590 km per charge.
Form, Function, and Signature Design
Beyond performance, Brembo and Polestar collaborated on visual identity. The gold calipers, unique to the Performance Pack, symbolize precision engineering and refined performance—signature traits for both brands.
With each tap of the pedal, Polestar drivers engage a system refined through decades of racing innovation. The result: braking technology that doesn’t just stop the car—it keeps it ahead.
