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 Tennessee

Tennessee is a fast-growing EV market, driven by Nashville and Knoxville. The state hosts Volkswagen's Chattanooga EV assembly plant and is a major hub for EV battery manufacturing (LG Energy Solutions in Holland). TVA's low electricity rates are a major advantage.

Incentives & Programs

Tennessee has no state EV tax credit. Federal incentives apply. TVA (Tennessee Valley Authority) offers some of the lowest electricity rates in the US and partners with utilities on EV programs. Nissan's Smyrna plant (near Nashville) is transitioning to EV production.

Charging Infrastructure

I-40, I-24, and I-75 corridors are well-covered. Nashville and Knoxville have solid charging networks. Memphis is growing. Appalachian rural stretches are more limited.

Grid & Energy Source

TVA's grid is approximately 40% nuclear (with several plants), ~25% natural gas, and growing solar and wind. The nuclear base makes Tennessee EV charging relatively clean among Southern states.

TennesseeElectricity Rates & EV Savings

The average residential electricity rate in Tennessee is $0.13/kWh, which is below the national average of $0.17/kWh. With a gas price of $3.30/gallon, Tennessee ranks as a favorable state for EV ownership.

Moderate climates provide near-optimal EV performance year-round. Expect battery range close to EPA estimates and consistent charging costs across seasons. 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.
