Polestar 4 vs Mazda CX-70

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.

For mine, the CX-70 is the pick of Mazda's premium SUV range, and if you can survive without a third row of seats, it's significantly cheaper than its CX-90 twin, too.

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.

Yes, the Mazda premium SUV range can look a little same-same, but Mazda insists there are critical differences.

That said, if you can immediately spot the difference between the CX-70 and CX-90 without taking a peek inside, you're doing better than me, given it is the same exact dimensions as Mazda's three-row flagship.

Sure, Mazda talks about things like this design being a “passion pursuer” that serves up "dignified performance” – all of which sounds utterly ridiculous – but the less marketing-speak version is that it looks like a shapely large SUV that ditches the boxy dimensions of a proper 4WD for a more sleek and swooping profile.

Inside, it's a plush and premium-feeling space, with lovely cabin materials, plenty of tech, and plenty of space.

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 CX-70 measures a substantial 5120mm long, 1994mm wide, and 1745mm tall, and it rides on a 3120mm wheelbase.

It will tow 2.5 tonnes no matter which engine you choose, and the expansive boot will swallow between 589 litres and 2015 litres, depending on how you configure the backseat.

All of that space translates to a hugely airy backseat experience, with the second row able to be fixed in a position that either prioritises leg room or boot space.

With the former, you've got tons of space in the second row. I'm 175cm, and my knee and leg room was ample, with only the intrusive tunnel that runs down the middle-centre of the cabin eating into leg room for the middle passenger.

There are also air vents and temp controls, twin USB charge ports, seat heating in the window seats and swathes of very nice materials.

The boot is massive, too. I can't even reach the back of the rear seats when I lean into it, and Mazda says it will swallow smaller surfboard or SUPs without needing to resort to roof racks.

Under-floor storage adds a bit more security for precious items, too.

We'll drill down on this a little more in the practicality section, but it's important to note here that the CX-70 is the same size as the CX-90 – both are 5120mm long, 1994mm wide and 1745mm high — which means the only real difference between the two models is the third row of seats in the CX-90.

And, as it turns out, that's a very expensive pair of chairs. The CX-70 starts with the GT trim at $75,970 before on-road costs for the petrol or $77,970 for the diesel, and then climbs to the Azami trim, which is $82,970 or $84,970.

The CX-90, though, is $82,577 or $85,785 for the GT, or $91,461 or $93,030 for the Azami.

That makes the CX-90's third row at least a $6600 option, but as much as an $8000 upgrade. Mazda has made moves to address this, with a drive-away "plate clearance" that closes that gap, but we suspect those offers will become permanent fixtures to make the jump from 70 to 90 less ferocious.

Anyway, Mazda has thrown just about everything they've got at the CX-70. The GT kicks off with plenty of high-end gear, including 21-inch black alloy wheels, adaptive LED headlights, a panoramic sunroof and a handsfree powered tailgate.

Inside, there are twin 12.3-inch screens with Apple CarPlay and Android Auto, a 12-speaker Bose stereo, leather seats that are heated front and rear, three-zone climate control and a heated steering wheel.

The Azami then adds things like ambient lighting, black Nappa leather seats, which are now ventilated in the front, footwell lighting, body-coloured wheel arches and lower cladding and body-coloured door handles.

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.

You can have one of two engines in the CX-70, with the cheapest being a 3.3-litre, six-cylinder turbo-petrol, producing 254kW and 500Nm. There's also a 3.3-litre, six-cylinder turbo-diesel, making 187kW and 550Nm. Both are equipped with a 48-volt mild hybrid system to marginally reduce fuel use.

All models are AWD, and pair with an eight-speed automatic transmission.

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.

Petrol-powered cars will sip 8.1L/100km on the combined cycle, while the diesel drops that to 5.4 litres.

Both models get a 74-litre tank, meaning a theoretical driving range of around 900kms in the petrol, and almost 1400kms in the diesel.

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. 

Interestingly, the CX-70 has been tagged as the expected smallest seller of Mazda's premium SUV range, but I reckon it just might be the pick of the bunch.

Every one of the CX-0 models (60, 70, 80 and 90) all get slightly different suspension tunes, and while you can find harsh edges in the other models, the CX-70 feels utterly composed and refined, at least on the smooth-ish roads of our launch test route.

Perhaps most surprising, though, is the CX-70's ability to hold its own on a properly twisting road. We expected lots of weight transfer and the high-pitched sounds of tyres screaming out in pain, but instead found Mazda's massive SUV served up grip, composure, and very little in the way of sea-swell-style body roll.

The two big six-cylinder engines also feel perfectly suited to a vehicle in this space. There's tons of power whenever you need it, and solid levels of refinement in terms of engine noise or diesel rattles.

For mine, the petrol engine is the pick though, feeing just a little smoother than the diesel option. The latter can feel a bit jerky at slower speeds, whether that's the power delivery or the gearbox, and it doesn't seem to happen with the petrol engine.

The biggest caveat, though, is that we haven't driven the CX-70 in its natural environment, the city and suburbs, so while it largely shone on flowing country roads, how it performs on roads like the ones near your place remains a bit of a mystery.

The CX-70 hasn’t been ANCAP tested, but it does arrive with a pretty stacked safety offering, including a 360-degree-view camera, blind-spot monitoring, front and rear cross-traffic alert, and a total of eight airbags, including a knee airbag for the driver.

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.

Servicing is not particularly cheap in the CX-70, and the service intervals, at least in the diesel, feel a little short, too.

Buy that one, and you’ll be visiting the dealership every 12 months or 10,000kms, and the first five years of ownership will cost you $3298.

Petrol cars require servicing every 12 months or 15,000kms, and five years will set you back $3436.

The CX-70 is also covered by Mazda's five-year, unlimited-kilometre warranty.
