The Polestar 4 has a very attractive design that doesn’t go unnoticed.
The interior is elegant, comfortable and finished with good materials.
Easy to drive, great grip on the tarmac and strong acceleration.
For the price, there are things to improve to be competitive with other brands of equal quality and technology; it needs meaningful upgrades — e.g., better driving ADAS, true autonomous parking and the ability to move the car remotely if you can’t get inside. Improving charging times is essential, and not having a rear window while relying on a camera in the interior mirror shouldn’t be a cause for concern. Otherwise, a spectacular car with a gorgeous design.
