About the 2026 Polestar 4

The Polestar 4 is a coupe-SUV that makes the controversial choice to eliminate the rear window entirely — replaced by a rear-view camera feed. This allows a sweeping glass panoramic roof over rear passengers while maintaining the coupe roofline.

Advantages

✓Panoramic glass roof over rear passengers creates a light, airy cabin

✓200 kW DC fast charging is competitive

✓Long-wheelbase design provides more rear legroom than the exterior suggests

✓300 hp single-motor or 544 hp dual-motor available

Considerations

✗No rear window — some buyers find the camera view disorienting

✗3.3 mi/kWh efficiency is average for the class

✗$56,300 puts it against better-known competitors

✗Polestar service network limitations apply

Ideal Buyer

Design-forward buyers who want the most distinctive coupe-SUV on the market. Those who prioritize the rear passenger experience (children, rear-seat riders). Buyers willing to accept the camera-only rear view.

vs. Gas Equivalent

Competes with BMW X4 and Mercedes GLC Coupe in the coupe-SUV segment. Gas equivalent is approximately 24 MPG for comparable coupe-SUVs.
