Polestar Polestar 4 I (2024 – Présent)

Reliability score : 8.3/10

The Polestar 4 (Generation I) is a 100% electric D-segment coupe SUV, positioned in terms of size and price between the Polestar 2 sedan and the large Polestar 3 SUV. Based on the Geely group's modular SEA (Sustainable Experience Architecture) platform (shared with the Zeekr 001 and Volvo EX30), it stands out with a radical design choice: the total absence of a rear window, replaced by a high-definition digital interior rearview mirror connected to a roof camera. This choice allows the panoramic roof to stretch beyond the heads of the rear passengers, offering exceptional roominess. Although very recent, the model promises excellent performance and generous range thanks to its 100 kWh battery. Estimated overall rating: 8/10 (pending long-term reliability feedback).

✅ Strengths

⚠️ Weaknesses

🎯 Verdict

The Polestar 4 is a technologically advanced and bold electric vehicle. Its choice to remove the rear window is polarizing but offers a real benefit in terms of roominess. Based on Geely's excellent SEA platform, its mechanical and electrical fundamentals are solid. However, as with many ultra-connected new-generation vehicles, early buyers often bear the brunt of software bugs (Android Automotive, driving aids management). Buying advice: The Long Range Single Motor version is the most rational choice, offering the best range and performance that is already more than sufficient. It is advisable to ensure the vehicle has the latest software updates before delivery. If you are sensitive to visual fatigue, it is imperative to test the digital rearview mirror before purchasing.
