Polestar 4 vs Volvo Ex90

What's the difference?

Polestar may be a Tesla rival but the Polestar 4 looks and feels much more premium than the Model Y. The brand has taken its time to get the cabin just right and the sustainable materials don’t feel cheap in any way. In fact, this car feels special.

I may not be a fan of some of the tech - the digital rear-view mirror, for example - but many people will be drawn to the car because of these features.

On the road, the Polestar 4 is a cracking EV, with excellent driving range and a fun factor that can’t be denied. That aftersales offer is just the cherry on the cake.

This is Polestar’s best chance yet of being accepted by the masses.

The new Volvo EX90 Ultra Twin Motor Performance strikes a great balance between sophistication and practicality. It looks sharp, drives beautifully, and delivers a solid range with fast charging to match. Adding to that is a comfortable, family-friendly cabin with space for seven. It’s hard not to be impressed.

There are a couple of technology beats it misses but it's still an easy SUV to live with.

Polestar pitches itself as a design-led brand and so far that checks out. The Polestar 2 is a striking sedan, the 3 is a bold, boxy, big SUV and now the 4 is the latest sexy addition to the range.

As mentioned, it is technically a medium SUV but it has a distinct fastback look. Polestar calls it a coupe-SUV. Whatever it is, it looks smashing in the metal.

The sleek silhouette pairs nicely with the split LED headlights and low-set front end. While there is an elevated ride height, it manages to sit low enough to the ground to look sporty.

The most interesting angle of the Polestar 4 is the rear. This car does not have a rear windscreen. The tailgate is made up of aluminium panels instead of glass, but the massive panoramic roof stretches back to the top of the tailgate.

The squared-off rear sits up high and houses gorgeous tail-lights that span the width of the car. Even though the rear is controversial given the lack of window, it’s probably the Polestar’s best angle. It’s unique and striking.

The Polestar 4’s interior design is best described as stylish minimalism. It is much more interesting than Tesla’s appliance-like cabin design, and it’s clear a lot of thought has gone into the interior. There are virtually no buttons which helps the look, but that can impact practicality. 

The integrated air vents look stunning as does the flat-bottom steering wheel.

A mix of whites, and light and dark grey materials are broken up by pops of colour like gold seatbelts. 

Recycled material is found throughout including the floor mats, dash toppers and seat upholstery, some of which is inspired by the fashion and sportswear industries. But being Polestar, it’s with a sustainable twist.

The EX90 has swathes of smooth body panelling and a closed-off grille, as we've come to expect from a modern EV. The rear roofline tapers gently, giving it a sleek profile, while the black body moulding around the base and frameless mirrors add some visual interest.

It’s a clear departure from the boxier XC90 and you won’t mix them up but it still features those signature 'Hammer of Thor' LED headlights, which I really like.

The Ultra rides on 22-inch alloy wheels which help fill the arches nicely without making the car look oversized or flashy. The soft-close doors are a luxe touch and the overall fit and finish is up there with the best in the segment.

It shares its platform and technology with the Polestar 3, so if you're familiar with that model, the dashboard and centre console layout will feel very familiar.

I’m a fan of the clean, minimalist look and it works well with the panoramic sunroof, which brings in loads of light. A future update will let you switch the roof from clear to opaque, which should be a nice touch come summer.

The ambient lighting is cleverly integrated with the birch wood trim, and there are subtle ambient lights throughout the cabin that give it a business-class vibe.

And since it’s fully electric, there’s no transmission tunnel, so the middle row gets a completely flat floor. That also means extra space, with a handy storage cubby added under the centre console.

Sliding into the driver’s seat, the first thing I notice is how high the centre console sits. This is clearly a Polestar thing because it’s similar to the 2. This adds to the sporty feel of the cabin, but I don’t know if it needs to be that high.

It does however liberate a massive amount of storage space under the console. You could fit a handbag, shoes or other items there, and Polestar offers accessories like bicycle-esque bottle holders. 

There’s more storage in the smallish central bin which also houses two USB-C ports, a half-hidden phone charging pad, and door bins that will fit a larger bottle, but only lying down.

The seats are comfortable and the cloth-like sustainable material in the Singe Motor grade looks great, but it can grip on to clothes a little. The perforated Zinc-coloured ‘animal welfare’ Nappa leather in the Dual Motor is stunning and probably what I would opt for. Which is rare given I am no leather fan. But whatever the material, there’s a decent amount of support on offer. 

If you opt for the Nappa upgrade ($7000) you get Harman Kardon speakers embedded in the front headrests. It’s an interesting addition but it sounds quite cool when you realise where the sound is coming from.

Aside from the ‘play’ dial on the console, there are very few visible buttons. Meaning every function is housed in the central 15.4-inch landscape digital display.

I recently spent some time in another new Geely Group product - the Volvo EX30 - which has a similar set-up.

Thankfully, the menu is easy to navigate and the main screen is split between nav (running Google Maps of course) and up to four other functions, including apps like Spotify, a quick link to often-used controls and whatever else you want to customise.

Aside from the visually appealing graphics and colours, the display is crisp and easy to get your head around. The air con is easy to access and you use the screen to change the direction of the vents, which oscillate on the passenger side. 

The ambient lighting which is solar system themed is pretty cool, too. You pick the colour by planet. And the ‘Hey Google’ command appears to work well.

However, functions like opening the glove box should still be a physical button. There is no reason it needs to be housed in the screen. Also, adjusting the exterior mirrors and steering wheel required a lesson from the Polestar team. You can do it via the screen, or by using the smart controls on the steering wheel that change depending on what function you need. 

Again, this is very clever tech, but is it that necessary? Just because Tesla does something, doesn’t mean every other EV brand on the planet needs to follow suit. 

Then we get to the digital interior rearview mirror. While the lack of a rear windscreen does not impact the look of the car negatively, it’s another element that feels like tech for tech’s sake. Is there really enough of a benefit to interior space to justify this radical change to the car?

The display is clear but when you look at it then the exterior mirrors, the object in the display seems closer than the mirrors. There’s also no washer for the camera, with Polestar suggesting the angle means it doesn’t need one. The question remains, what happens if it malfunctions? 

I realise you can’t see out the back of plenty of vehicles, like trucks and, often, delivery vans. It’s also something you have to navigate when you pack your car full of gear for holiday and can’t see past all the luggage. And I appreciate many more people will be drawn in by the tech of it all. But for me it remains the answer to a question no one asked.

Moving to the rear, the slightly bucketed seats are plush and supportive and there is acres of legroom thanks to the Polestar 4’s 4.8-metre wheelbase. It is a spacious cabin no doubt, but the placement of the battery pack under the floor means your knees sit up higher than they would in an ICE car. It’s a similar phenomenon in Tesla models. There’s also no toe room under the front seats. 

You can, however, recline the rear seats slightly, making for a more relaxed vibe back there. There are amenities like rear digital climate controls, more USB-C ports, chest and knee-level air vents, and a fold-down arm-rest with cupholders, but big bottles won’t fit in the doors.

The boot appears shallow but there is under-floor storage where you can house the charging cable as well as flatter items. All up you get up to 526 litres of cargo space (that includes 31L under-floor), increasing to 1536L with the 60/40 split rear seats folded, while a front cargo space swallows 15L.

Polestar only offers a tyre repair kit for the 4, so no temporary spare. 

The EX90 nails the balance between luxury and everyday usability. Up front, there’s loads of head, leg and elbow room, and it’s easy to get in and out thanks to the 216mm ground clearance and wide door apertures.

That said, the flush door handles can be a bit temperamental as they don’t always pop out when you approach and the key card only works from the driver’s side, which can be annoying.

Once you’re in, the front seats are superb. They’re seriously comfortable, with heating, ventilation, massage and extendable thigh supports that make long trips a breeze. It’s easy to find a great driving position and just settle in.

Storage up front is clever and generous. There’s a large glove box, a deep centre console with a hidden cubby, a shelf under the floating centre stack, plus cupholders and big door bins. It's well thought out and practical.

The 14.5-inch multimedia screen looks fantastic and is responsive. Now, I’m a button girl, and usually having to rely on a screen for everything would bug me but this set-up works.

You can pin your favourite features like climate and media controls to the bottom of the display for easy access, and the voice assistant is usually really capable, so you can stay hands-free when needed.

Built-in Google Assistant, Google Maps, YouTube, Spotify, plus wireless Apple CarPlay and Android Auto make tech integration smooth. Navigation directions show up clearly in both the 9.0-inch digital instrument cluster and the colour head-up display, which is a nice touch.

I experienced a couple of tech gremlins toward the end of my week with the car. The Google Assistant stopped picking up my voice commands and calls wouldn’t route through the sound system once connected.

Thankfully, both issues seemed to resolve themselves without intervention, but it's worth noting in case it’s a software quirk that pops up from time to time.

The second-row seats are ergonomic but a little firm - still comfy enough for long trips, especially with heating for the outboard seats.

Access is easy, and my eight-year old had no trouble climbing in or out. The booster seat integration has moved to the middle seat only (instead of both outboards), which might limit flexibility for some families, but for us it works fine.

There are ISOFIX mounts on the outboard seats and three top-tether points across the second row, and yes, you can fit three child seats side by side. Amenities in the second row are excellent with two USB-C ports, air vents, dual-zone climate, map pockets, cupholders and decent storage bins.

The third row is, as expected, best for kids, as toe room is limited and the access is child-sized. Still, it’s well-appointed with two cupholders, USB-C ports, and air vents built into the C-pillars. Even better, it gets two top-tether anchor points, which is a huge bonus for big families.

Boot space is solid because even with all seats up, you get 324L, including a useful underfloor compartment. Fold the third row and it jumps to 697L.

You can also manually raise or lower the boot height thanks to the active air suspension, and the third row folds electrically. There’s also a 12-volt socket and a powered tailgate you can operate via the Volvo app or the multimedia screen.

Up front, there’s a 34L frunk which is ideal for storing charging cables or a tyre repair kit, keeping everything neat and separate.

There are two grades available for the new Volvo EX90, and for this review, we're testing the flagship Ultra Twin Motor Performance.

While it shares the same motor configuration as the lower Plus variant, the Ultra gets a performance tweak that improves its 0–100km/h sprint time. Naturally, it also comes with a suite of luxurious extras befitting its flagship status.

Starting at $134,990, before on-road costs, the Ultra sits comfortably in the middle of its electric upper-large SUV rivals.

It’s more expensive than the Kia EV9 GT-Line (from $121,000) but undercuts the luxury-laden Mercedes-Benz EQS 450 4Matic (from $222,400). It also only costs $6600 more than the top-spec PHEV XC90, making it a compelling step up if you require electric performance and efficiency.

With a claimed WLTP driving range of 570km, the EX90 Ultra holds its own in the segment, offering solid long-distance capability.

The Ultra is well-equipped as you’d expect with electric front seats that feature heat, ventilation and massage functions. There is a heated steering wheel, fixed panoramic sunroof and a 25-speaker Bowers & Wilkins sound system.

Volvo has confirmed the panoramic sunroof will have an adjustment setting between clear and opaque in a future update, as it currently doesn’t have a blind.

Some great practical and family-friendly features include heated rear outboard seats, powered third-row seats, a powered tailgate, a 34L frunk for charging cables and an integrated kid’s booster seat in the middle row for those transitional stages.

The well-rounded suite of technology is based on the EX90's new Polestar 3 cousin and includes four USB-C ports plus a digital key via the Volvo app. The app also allows you to check on the status of the vehicle, open and close the boot lid, remotely unlock/lock the vehicle and pre-set the internal climate.

There is a large 14.5-inch touchscreen multimedia display that features wireless Apple CarPlay and Android Auto, satellite navigation (with live traffic updates and directions that are pulled into the colour head-up display) and a 9.0-inch digital instrument cluster. The system also has a suite of built-in apps like Google Assistant, Google Maps, YouTube, Spotify etc. 

The battery electric Polestar 4 comes with two powertrain options. 

As its name suggests, the Long Range Single Motor has one motor driving the rear wheels only, and it pumps out 200kW of power and 343Nm of torque. That’s enough to help propel the SUV from zero to 100km/h in 7.1 seconds, on the way to a 200km/h top speed. 

The Long Range Dual Motor has a second motor on the front axle for all-wheel-drive grip, and the power and torque is bumped to 400kW and 686Nm, respectively. You’ll get to 100km/h a lot quicker at 3.8 seconds, too.

The Ultra is all-wheel drive with twin electric motors, one on each axle. Combined, they deliver a hefty 380kW of power and 910Nm of torque. That translates to a 0–100km/h sprint in just 4.9 seconds, which is seriously impressive for a big SUV.

Do we need it to be this fast? Absolutely not. But do I appreciate the gumption? You bet I do.

The Polestar 4 uses a 400-volt, 100kWh lithium-ion battery.

The Long Range Single Motor has a healthy EV driving range of up to 620km on the WLTP standard, and energy consumption ranges from 17.8 to 18.1 kilowatt hours per 100 kilometres.

Range in the Dual Motor drops to a still very useful 590km and efficiency sits between 18.7 and 21.7kWh/100km.

We were in and out of different grades at the launch so didn’t capture real-world efficiency but we will when we do a full review soon.

AC charging is at a rate of 11kW, but if you opt for the $8000 Plus Pack that increases to an impressive 22kW which ensures a zero to 100 per cent home charge (32-amp) in just five and a half hours.

DC charging capacity is up to 200kW and Polestar says you should be able to get from 10 to 80 per cent full in about 30 minutes. 

These add up to solid figures for the price and segment. 

It comes with a type 2 and CCS2 charge port and a home charging cable.

The official WLTP energy consumption figure for the EX90 Ultra is 16.9kWh/100km, and after a good mix of open-road and urban driving, I averaged around 20kWh/100km which isn't bad at all for a vehicle of this size.

The strong regenerative braking helps here, and if you time your deceleration right, you can enjoy a proper one-pedal driving experience, which makes city driving feel effortless.

The EX90 uses a Type 2 CCS charging port and packs a massive 111kWh lithium-ion battery, good for a driving range of up to 570km (WLTP).

Charging speeds are impressive as it supports up to 11kW on AC and a hefty 250kW on DC fast chargers. That means you can go from 10–80 per cent in as little as 35 minutes on a 250kW charger, or in around 10 hours on an 11kW home set-up.

Some EVs tend to blend into one another when it comes to the drive experience. Thankfully, that’s not the case with the Polestar 4, which is the fastest Polestar model to date.

I drove the Single Motor and Dual Motor with the Performance Pack back to back, and both hold appeal for different reasons. 

The Single Motor is the everyday Polestar 4 and it is the one I would choose. There is ample power and torque on offer and that 7.1-second 0-100km/h sprint time is nothing to be sniffed at.

Riding on the standard 20-inch aero wheels with a high sidewall, the Single Motor is composed with a comfortable ride quality. The drive from Adelaide via various winding and pockmarked roads to the Barossa Valley highlighted how well the Single Motor can handle these sorts of surfaces. It’s not as comfy as a Camry, but Polestar has ironed out most of the firmness.

Steering feels light but super sharp in the Single Motor and while there is a hint of body roll, it is still exceptionally capable on the twisty stuff. It also doesn’t feel anywhere near its 2230kg kerb weight.

The Dual Motor is a different beast, especially when paired with the Performance Pack. That pack adds, among other items, Brembo brake callipers and a ‘Polestar Engineered’ chassis tune.

It is brutally quick from a standing start. Like ‘pull your face back’ quick. Zero to 100km/h in 3.8sec to be precise. It’s a hoot, but it is much more than just a straight-line speed machine. 

The Dual Motor carves up corners, again with slight roll, but it has no business being this sharp given its dimensions and weight. We sprinted (safely) through bends better suited to a tiny performance hatch with ease. 

You can adjust the chassis to your preference. Suspension runs from 'Standard' to 'Nimble' and 'Firm', and steering is either Standard or Firm, the latter adding quite a bit of weight to the steering. Power delivery is either 'Range' or 'Performance'. Obviously, the latter is the most fun. 

Even in Standard suspension mode, the ride is much firmer than the Single Motor, which isn’t helped by the massive 22-inch wheels. It is, however, never unbearable. In fact, it’s more than fine on some of the average roads we encountered. 

The Polestar 4 is well insulated, ensuring a hushed cabin. 

Smooth and effortlessly powerful - that’s the best way to sum up the EX90 on the road. Despite its size, you don’t feel the bulk from behind the wheel. It’s nimble when it needs to be and wickedly quick off the line. Even under hard acceleration, I always feel in control, which is a huge plus for something this punchy.

You can customise the steering feel, and I preferred it on the firmer setting as it gave the best feedback without feeling heavy. The active air suspension does a great job of absorbing rough surfaces without softening the handling, so there’s no floatiness, just a composed, comfortable ride.

Inside the cabin, it’s beautifully quiet. That signature EV silence makes the space feel refined, with just the occasional tyre rumble at higher speeds, depending on the road surface but it’s never intrusive.

Visibility is mostly great from the front and sides, but the rear window feels miles away in the mirror, and the B-pillars are a little thick, so there’s a minor blind spot to be aware of.

Parking is easier than you’d expect for something of its size. The 360-degree camera is super clear, and there are plenty of parking sensors. The 12m turning circle is pretty standard, but it still felt totally manageable in tight shopping centre car parks.

The EX90 hasn’t been ANCAP-tested yet, so it’s currently unrated but being a Volvo, you can bet it’s packed with safety smarts.

It features a comprehensive suite of advanced safety tech, including side exit assist, emergency call functionality and a child detection system using radar sensors to monitor for movement in the cabin after the car is locked, designed to prevent children being accidentally left inside.

The second- and third-row seats all feature top-tether points, with ISOFIX anchors on the two outer second-row positions.

There are seven airbags, including a front-centre airbag and curtain airbags that cover all three rows, which is a win for families.

On top of that, it’s equipped with Volvo’s 'Pilot Assist' suite, which includes adaptive cruise control with lane centring, lane departure alert, lane keeping aid, blind-spot monitoring with steering assist, rear cross-traffic alert with automatic braking, 360-degree camera system, front/rear parking sensors and autonomous emergency braking with forward collision warning.

Volvo is also working toward occupant sensing and driver monitoring systems that go beyond the usual alerts. The EX90 includes an interior radar system sensitive enough to detect the micro-movements of breathing, aimed at preventing hot car deaths.

It’s being pitched by Volvo as one of the more safety-forward SUVs on the market, even before it earns its official crash score.

Covering the Polestar 4 is a five-year, unlimited kilometre new-vehicle warranty, and an eight year, or 160,000km battery warranty. 

Complimentary roadside assist covers you for five years too.

The service schedule is every two years or 30,000km.

But the big news is that Polestar won’t charge you a cent for servicing for the first five years, or 100,000km of ownership, whichever comes first - it’s complementary.

This is an outstanding aftersales offer.

The EX90 is covered by a five-year/unlimited km warranty, which is on par with most rivals, though Kia still has the edge with its longer coverage. Servicing intervals are every 12 months or 15,000km, whichever comes first.

As for costs? For the first five years, servicing is included in the purchase price, so while it’s technically not ‘free,’ it does mean no extra out-of-pocket expenses for scheduled maintenance during that time and that’s pretty solid value in this segment.
