MADRID, Spain — Historically, carmakers have used windows as a selling point when there are more of them than you might expect. Volkswagen’s 23-window Bus, which was officially known as the Deluxe Microbus with Samba Package, was an upmarket trim that’s highly sought-after today, for example. On the other side of the pond, the flagship Citroën XM was available with a 13th window that kept wind out of the cabin when the hatch was open. With the 4, Polestar argues the industry has reached peak window.

As far as eccentricities go, the lack of a rear window isn’t a minor one. We’re not talking about a van you’d see in a contractor’s fleet; this is a premium EV. There’s more to it than a glass-less hatch, however. After driving a pre-production car on a test track, I’m taking the 4 out on public roads.

First, a word about positioning. Don’t read too much into the “4” nameplate; Polestar names its cars in the order that they’re launched in. The 4 is, quite simply, the fourth Polestar model unveiled, and it’s positioned below the 3 in terms of pricing and size. The segment it competes in is relatively hard to pin down. It’s an SUV in the same sense that a taco is a sandwich: it ticks most of the right boxes on paper but it doesn’t really look the part. It’s more of a tall-ish sedan-hatchback mash-up. Or, maybe a crossover in the literal sense of the term rather than in the commonly accepted sense.

Regardless, the 4 certainly turns heads. There’s nothing else quite like it on the road. It falls in line with Polestar’s design language by adopting styling cues like T-shaped headlights, a grille-less front end and a thin rear light bar, but it’s not a photocopy of an existing model. It has its own identity.

Polestar claims that it has a very good reason for leaving out the rear window. “We wanted to have a coupe body style for aerodynamics and at the same time get a really spacious interior,” Maximilian Missoni, the brand’s head of design, told me. The window-less solution made it possible to shift the D-pillar back and gain a few inches. “Another problem with coupes is that [in the rear-view mirror] you see a lot of your own interior – you see the headrests and maybe your passengers,” he added.

The sheetmetal hides the modular SEA architecture shared with several other brands in the Geely empire. Versions of this basic platform underpin the Volvo EM90 minivan sold in China, the Volvo EX30 and the Lotus Eletre, among other models. Buyers will have two configurations to choose from at launch. The base model is called Long Range Single Motor, and it ships with — you guessed it — a single electric motor that zaps the rear wheels into motion. It’s rated at 272 horsepower and 253 pound-feet of torque, and it’s equipped with a 100-kilowatt-hour lithium-ion battery pack.

Next up is the Long Range Dual Motor, which gets two motors (one per axle) for through-the-road all-wheel-drive. The second motor increases horsepower and torque to 544 and 506, respectively. This trim uses the same battery as the rear-wheel-drive version. Both drivetrains are built around a 400-volt electrical system, and range checks in at up to 300 miles with rear-wheel drive or up to 270 miles with all-wheel drive. Charging from 10% to 80% takes about 30 minutes with a 200-kilowatt charger.

The 4 shares about 85% of its infotainment system with the 3, but the software is displayed on a portrait-oriented 14.5-inch touchscreen instead of on a landscape-oriented one. The system is Android-based, and Polestar designed the user interface in-house with clear, easy-to-read icons and a split-screen functionality. The driver can notably select the ratio of the split; you can display the navigation system on the left 3/4s of the screen and show the media and phone widgets on the right 1/4, for example. Vice versa works, too, as does a 50/50 split. This cool feature makes the system more intuitive and less distracting to use. “We are not developing phones. We are making cars, and we have distractions to worry about,” Ruben Rodriguez, the company’s head of UX design, told me.

Like the 3, the 4 follows a minimalist approach to interior design. You’ll find very few buttons in the cabin. There are a handful on the steering wheel, they’re notably used for functions like adjusting the door mirrors and the steering column, and a volume knob on the wide, slanted center console. This extensive reliance on the touchscreen could catch old-school drivers off guard, but it’s increasingly becoming par for the course across the industry. Touchscreens can also add a touch of novelty to the experience: Polestar named the ambient lighting modes after the planets in the solar system, and you can poke your way through the galaxy while learning details like the length of a day on Mars.

My time behind the wheel was limited to the dual-motor version, and my test car was equipped with the optional Performance Pack. It doesn’t increase horsepower but it adds specific chassis tuning, 22-inch wheels wrapped by Pirelli P-Zero tires, Brembo brakes and gold-colored seatbelts. The huge brakes aren’t overkill: This is a roughly 5,200-pound car that gets from zero to 60 miles per hour in 3.8 seconds.

Performance is the 4’s dominant trait, at least in this configuration. It feels even quicker than the 3.8-second figure suggests thanks to the instant torque delivered by the electric motor, and the relatively low center of gravity combined with the 50/50 weight distribution give it better handling than you’d assume considering its size and weight. It’s not as sharp around a bend as the 3, which has a trick torque-vectoring rear axle, but the effort Polestar put into making the 4 engaging to drive shows. 

Unlike the 3, which rides on an air suspension system, the 4 features a conventional steel setup. It’s fixed in the rear-wheel-drive model and adaptive in the all-wheel-drive model. The latter gives the driver three modes called Standard, Nimble and Firm, respectively, to choose from. The same menu in the touchscreen also lets you select two types of power delivery (Range and Performance), three flavors of steering feel (Light, Standard and Firm), and three levels of one-pedal driving (Off, Low and Standard). By playing around with these settings you can create a tailor-made driving profile. The difference between these various settings is perceptible even in normal driving conditions. Hitting the suspension’s Firm setting reduces body roll at the expense of smoothness, while the steering gets noticeably heavier in Firm mode. You can guess which mode you’re in without looking at the screen.

Select the softer suspension and steering settings and the 4 becomes a comfortable place to travel in. Missoni’s words ring true: There’s a ton of space in both rows. Was that worth sacrificing the rear window for? It depends on your perspective. At its core, there’s nothing terribly unusual or alarming about the new system. Developed by Michigan-based Gentex, it consists of a 2.5-megapixel camera integrated into a little alcove on the roof that sends footage to an 8.9-inch digital rear-view mirror. You can flip down the mirror to take a look at which kid is throwing the punches in the back seat.

Our experience with camera-based mirrors has been mixed. One of my colleagues ran into glare-related issues with a similar system in the Volvo C40. I didn’t experience anything like that in the 4, but I thought the mirror was positioned too far back. I’d have moved it a few inches toward the windshield. Ultimately, it’s a matter of preference — that’s often the case with new technology. You might hate it, or you might love it. The problem is that if you hate it, you don’t have a second choice. It’s not like you can pay Polestar an extra $1,000 to order a 4 with a rear window and a real mirror.

So, have we reached peak window? The industry will decide. In a decade, the 4 will either stand out as a real oddball or as a trendsetter. Until then, it’s one of the more distinctive EVs on the market.

Polestar will initially build the 4 in Hangzhou Bay, China, though the model will also be manufactured in Busan, South Korea, starting in 2025. Pricing starts at $56,300 (including the $1,400 destination charge) for the rear-wheel-drive model and $64,300 for the two-motor all-wheel-drive version.
