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 South Dakota

South Dakota has very low EV adoption due to rural geography and a small population. Sioux Falls and Rapid City are the primary markets. The state's low electricity rates make charging cheap for those who adopt EVs.

Incentives & Programs

South Dakota has no state EV incentive. Federal incentives apply. MDU Resources and Black Hills Energy offer standard rate structures. The state has no income tax, which makes the federal income tax credit the primary incentive.

Charging Infrastructure

I-90 has limited DCFC — primarily at major stops like Sioux Falls, Mitchell, Rapid City. The Black Hills area (Mount Rushmore, Badlands) is improving. Long gaps exist on north-south routes.

Grid & Energy Source

South Dakota's grid is approximately 40% hydro (Missouri River dams), 30% wind, and 20% coal. The hydro and wind combination makes South Dakota's EV charging relatively clean, similar to neighboring North Dakota in wind characteristics.

South DakotaElectricity Rates & EV Savings

The average residential electricity rate in South Dakota is $0.13/kWh, which is below the national average of $0.17/kWh. With a gas price of $3.50/gallon, South Dakota 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.
