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.

EV Ownership in Idaho

Idaho has a small but growing EV market, centered on Boise and the Treasure Valley. The state's exceptionally low electricity rates ($0.11/kWh) make it one of the cheapest places in the US to charge an EV.

Incentives & Programs

Idaho offers no state EV tax credit, but federal incentives apply. Idaho Power offers time-of-use plans with off-peak rates that can go even lower. The base $0.11/kWh rate is already competitive with TOU off-peak rates in most states.

Charging Infrastructure

I-84 through Boise is well-covered. North-south stretches (US-95 toward Coeur d'Alene) are improving. Southern Idaho's rural stretches require careful planning. Boise has the best urban charger density.

Grid & Energy Source

Idaho's grid is dominated by hydropower (~65%) from dams on the Snake River and Columbia River system. This makes Idaho EV charging among the cleanest in the US, with among the lowest carbon footprints nationally.

IdahoElectricity Rates & EV Savings

The average residential electricity rate in Idaho is $0.11/kWh, which is below the national average of $0.17/kWh. With a gas price of $3.70/gallon, Idaho ranks as a favorable state for EV ownership.

Cold weather reduces EV range by 20–40% as the battery heats itself and the cabin. Use scheduled departure to pre-heat on shore power before driving. Your Polestar 4's 100 kWh battery provides up to 300 miles of EPA-rated range. Real-world range may vary by 10–30% depending on temperature, speed, and terrain.
