Polestar Unveils Electric Crossover Without a Rear Window

In the new Polestar 4 electric crossover, the company decided to do away with a feature familiar to every driver—the rear window. As a result, the manufacturer also had to replace the rearview mirror.

Instead of a traditional rear window, the Polestar 4’s panoramic glass roof extends backward, leaving no room for glass behind the rear seats. To compensate for this, a rear-facing camera transmits the image to a digital mirror inside the cabin, providing a wider field of view and eliminating obstructions such as passengers or body pillars.

This design also improves the car’s aerodynamics, which is particularly important for electric vehicles, where every detail affects range. In addition, the absence of a rear window allowed for a redesign of the interior layout.

Engineers gained more freedom to increase headroom for passengers and reinforce the body’s rigidity, particularly in the roof area. This is important for safety and comfort, and also helps maintain a coupe-like silhouette without compromising practicality.

Although the digital system provides a clear image and may even be more convenient in some situations, it relies entirely on electronics and cameras. Therefore, this solution is controversial among drivers.
