Polestar 4 - A Radical Shift in EV Design
BIKMAN TECHThe automotive world rarely sees a design choice as bold as the one found on the Polestar 4. In a sea of homogenous electric crossovers, this vehicle stands out not just for its sleek silhouette, but for a feature it deliberately lacks: a rear window. As a "new breed of SUV coupe," the Polestar 4 bridges the gap between the brand's fastback sedan and its larger SUV, aiming to solve the age-old compromise between aerodynamic style and rear-seat comfort. At BIKMAN TECH, we have analyzed the engineering behind this decision to help you understand if this futuristic machine is the right fit for your driveway.
1. Design Philosophy: The "Precept" Comes to Life
The Polestar 4 is the first production vehicle to fully embrace the design language of the Polestar Precept concept. Gone is the traditional grille; in its place sits the "SmartZone," a specialized panel housing radar sensors and heating wires. This shift from "breathing" to "seeing" gives the vehicle a distinct, robotic face, accentuated by the new "Dual Blade" split-headlight signature. The low, "shark nose" profile isn't just for looks—it significantly improves airflow, reducing drag and boosting efficiency.
2. The Rear Window Controversy
The most discussed aspect of this vehicle is undoubtedly the elimination of the rear glass. This wasn't done for mere shock value; it is a calculated engineering trade-off. By removing the window, engineers pushed the rear structural header rail further back, behind the heads of rear passengers. This allows the panoramic glass roof to extend well past the rear seats, creating a cavernous, airy atmosphere that defies the car's sloping roofline. To compensate for visibility, a high-definition, roof-mounted camera feeds a live video stream to a digital display where the rear-view mirror would traditionally sit.
3. Interior and Sustainable Materials
Inside, the cabin is a masterclass in Scandinavian minimalism and sustainability. Polestar has replaced traditional wood and chrome with innovative, circular materials. Options include a Tailored Knit upholstery made from 100% recycled PET bottles, inspired by the sneaker industry, and MicroTech, a bio-attributed vinyl. For those seeking a unique ambiance, the "Star Knit" illuminated deco on the door panels creates a diffuse glow, themed around the solar system, adding a layer of tech-focused luxury to the interior.
4. Performance Dynamics
The driving experience varies significantly between the two available configurations. The Long Range Single Motor version is rear-wheel drive, offering a balanced and efficient ride with 200 kW (272 hp). However, the Long Range Dual Motor variant transforms the vehicle into a performance powerhouse, delivering 400 kW (544 hp) and sprinting from 0 to 100 km/h (0-62 mph) in just 3.7 seconds. A key feature of the Dual Motor model is the front motor disconnect clutch, which disengages the front motor during cruising to save energy.
5. Suspension and Handling
Under the skin, the chassis architecture differs depending on your choice of motor. The Single Motor variant utilizes passive dampers with coil springs, tuned for a balance of comfort and control. In contrast, the Dual Motor model is equipped with semi-active ZF dampers. These continuously adjust to road conditions in milliseconds, allowing drivers to toggle between "Standard," "Nimble," and "Firm" modes. This active system does an excellent job of masking the vehicle's weight, providing a plush ride on highways and sharp responses in corners.
6. Battery and Range Efficiency
Both models are powered by a substantial 100 kWh battery pack utilizing NMC 811 chemistry. In real-world highway testing, the vehicle demonstrates respectable efficiency, though like all EVs, it is sensitive to speed and wheel size. The aerodynamic design contributes to a competitive range, making it a viable grand tourer. The inclusion of a standard heat pump helps mitigate range loss in cold weather, scavenging waste heat from the drivetrain to warm the cabin and battery.
7. Charging Capabilities
Built on a 400-volt architecture, the Polestar 4 supports DC fast charging at speeds up to 200 kW. While it may not match the ultra-high voltage systems of some competitors, the charging curve is relatively flat, allowing for consistent energy intake. Under ideal conditions, charging from 10% to 80% takes approximately 30 minutes. For home charging, an 11 kW onboard charger is standard, with a 22 kW option available in certain configurations for faster AC charging.
8. Technology and Google Built-in
The infotainment system runs on Android Automotive OS, centred around a 15.4-inch landscape touchscreen. This deep integration means Google Maps is the native navigation system, offering accurate range predictions and automatic battery preconditioning for charging stops. The interface is clean and responsive, though the reliance on the touchscreen for basic functions—like adjusting mirrors or the steering column—introduces a learning curve for drivers used to physical buttons.
9. Cargo and Practicality
Despite its coupe-like styling, utility remains a priority. The rear cargo area offers 526 liters (18.6 cubic feet) of space, expandable to 1,536 liters (54.2 cubic feet) with the seats folded. The lack of a rear window does not impede loading, and the space features a practical under-floor compartment. There is also a small "frunk" under the hood, though at 15 liters (0.5 cubic feet), it is best reserved for charging cables.
10. Human-Machine Interface Challenges
While the digital rear-view mirror offers a wider field of view than optical glass, it requires an adjustment period. Unlike a standard mirror, your eyes must refocus on the screen's surface rather than looking "through" it to the distance. This can be fatiguing for some users. Additionally, the minimalistic cabin design means navigating menus for simple tasks, which some reviewers found distracting while driving.
11. Sustainability Leadership
Polestar continues to lead in transparency, publishing a detailed Life Cycle Assessment (LCA) for the car. The Polestar 4 boasts the lowest carbon footprint of any model in the lineup at launch. The company also employs blockchain technology to trace the supply chain of high-risk minerals like cobalt and lithium, ensuring ethical sourcing and giving eco-conscious buyers peace of mind.
12. Who is the Polestar 4 For?
The Polestar 4 is a compelling choice for the design-forward consumer who values individuality and sustainability. It offers a unique blend of sports coupe aesthetics and SUV utility, without the typical compromises in rear headroom. While the digital interface and lack of physical controls may deter traditionalists, the engineering underneath—particularly in the Dual Motor variant—delivers a genuinely engaging driving experience. If you are ready to embrace the future of automotive design and can adapt to new tech, this electric performance SUV is a standout option.

הרכב נמכר כבר חודשים רבים ברחבי העולם אך לא בישראל ולא נראה שיש כוונה לעשות זאת. אם כך לשם מה הכתבה? האם מתוכנן למכור את הרכב בישראל בקרוב?
היי, מה מטרת הכתבה ?
היבואן לא מקדם את המותג, אולם המכירות בהרצליה עומד ריק מפולסטר.
הבורות היא שלך בלבד ושל מי שמקטין ללא סיבה
