Polestar 4 vs Rivian R1S

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.

While there are some obvious signs that the R1S is Rivian’s first mass-market vehicle, the good news for the company is that its problems are not impossible to overcome. The suspension needs retuning to improve the ride quality and the multimedia system’s software needs upgrading. But even with those issues the R1S left a positive impression.

This is a very stylish SUV with great space and excellent performance, that also happens to be electric, rather than relying on being electric as its primary selling point.

Rivian has put more effort into the design and finishes than many of its EV rivals and the result is a vehicle that can genuinely compete with the established premium players with more credibility.

The only catch is there’s no clear timeframe for when, or even if, this generation of R1S will make it to Australia. The brand has repeatedly spoken of its hopes of entering the market here without locking anything in, but given the current state of the EV sales it may pay off to wait until the conditions are right for a new, premium player to try its luck here.

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.

Design is another area where Rivian has carved out a unique position for itself. Whereas other brands, including Tesla, have focused on simplicity and aerodynamic efficiency, Rivian has given the R1T a unique style that looks interesting, different and most definitely not plain.

The oval daytime running lights make every R1S and R1T stand out from a mile away, even on LA’s busy freeways. The overall design is high quality and manages to strike a good balance between aesthetics, aerodynamics and practicality - even if it doesn’t suit everyone’s personal taste.

The cabin is worth highlighting in particular, because rather than go for the ‘minimalist’ look that so many brands are going for these days, with as little switchgear and different trims as possible to keep costs down, Rivian has opted for something more complex and, frankly, more impressive.

There’s a level of craftsmanship, a great mixture of premium materials (including some striking light wood options) that make the R1S feel like a stylish and relaxed environment inside the cabin. Our particular example had a great mixture of colours, textures and patterns that really elevated the cabin experience.

The technology is also nicely integrated into the design, rather than being the focal point, like so many other modern electric vehicles. It still offers the same level of technology - a pair of screens - but doesn’t rely on them to carry the design of the interior.

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 R1S comes standard as a seven-seat SUV, split across three rows (two in the first row, three in the second row and two in the third row). Space across the three rows is fairly typical for an SUV of this size, which is to say generous up front, good in the second row and a little bit tight in the back.

What is good though, is the length of the cabin allows for quite a spacious boot even with the third row in use, which is definitely not something all seven-seat SUVs can claim. Using a direct conversion from Rivian’s specifications that list cargo capacity in cubic feet, the R1S has a claimed 498 litres with the third row in use and up to 1331L with the third row folded down. There’s also 314L under the bonnet and another 144L underneath the boot floor (although that comes at the expense of a spare tyre).

As mentioned in design, Rivian has nicely integrated the technology into the cabin, with the 12.3-inch digital driver display and 15.6-inch central multimedia touchscreen feeling like a natural part of the car rather than a centrepiece. Rivian has also managed to incorporate eight USB-C charging ports spread around the cabin to keep everyone’s devices charged up.

However, while the technology is nice from an aesthetic design perspective, the same cannot be said about its useability. Like Tesla, Rivian has opted to go it alone with its multimedia system and has developed its own Google-based software that is not compatible with either Android Auto or Apple CarPlay. That would be acceptable, although still disappointing, if the system worked as well as Tesla’s, however the Rivian system is very slow. It repeatedly took several seconds to load between the various functions, which may not sound like long, but when you’re trying to get back to the navigation so you don’t miss your freeway exit a few seconds can make a big difference.

But, honestly, in this day-and-age, systems like this should work quickly and seamlessly, so it’s an area Rivian needs to improve.

On a positive note, Rivian does have some cool accessories for the R1S including what it calls a ‘Camp Speaker’ which is a US$400 option that it integrates into the sound system but is also removable, so you can pull it out of the centre console and listen to your music if you’re around the campfire or having a picnic.

When we drove the R1T in 2023 Rivian was still in the ramp up stage of production and was limited with what it could offer customers. Fast forward to 2025 and the brand now has both the R1T and R1S available with dual or tri motor powertrains, with a quad-motor powertrain expected by the end of the year.

The R1S Dual Standard begins the range at US$75,900 (approx. A$118,000), the R1S Dual steps it up to US$83,900 (A$130k) and the R1S Tri-motor completes the current line-up at US$105,900 (A$165k). While those prices are definitely in the premium end of the market the R1S is actually cheaper than the Tesla Model X, which is still on sale in the US market, and starts at US$86,630 (A$135k) and stretches to US$101,630 (A$158k).

For more context, the Audi Q8 e-tron starts at US$74,800, the BMW iX from US$87,250 and the Mercedes-Benz EQE from US$77,900.

Standard equipment across the range includes the 12.3-inch digital instrument display, 15.6-inch multimedia touchscreen, dual-zone climate control, heated and ventilated front seats, heated steering wheel, eight-way power adjustable driver and passenger seat and panoramic glass roof, so it certainly has premium levels of equipment.

We drove the range-topping RS1 Tri-motor which, aside from an extra motor, gets standard 22-inch alloy wheels, a dynamic glass roof, a soft-touch suede textile headliner as well as unique colour and trim options.

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.

As mentioned earlier, there are currently three versions of the R1S available, each with a different powertrain. 

The Dual Standard AWD has, unsurprisingly, dual motors (one at the front and one at the rear) which make a combined 397kW/827Nm. That’s enough for it to launch 0-60mph (0-96km/h) in just 4.5 seconds. The R1S Dual AWD has the same power, torque and acceleration figures, however it gets Rivian’s Large battery, which we’ll detail below.

The Tri-Motor AWD obviously has three motors, one on the front axle and two on the rear, which naturally provide more power, 633kW/1495Nm. With so much power and torque the Tri-motor is wickedly fast, taking just 2.9 seconds to launch 0-60mph.

If, for some reason, the Tri-Motor isn’t fast enough for you, Rivian has released the details on the Quad-Motor. It will have two motors on each axle providing a staggering 764kW (that’s 1025-horsepower!) and 1624Nm, enough to rocket it from 0-60mph in just 2.6 seconds and across the quarter mile in 10.5 seconds.

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.

Rivian offers three different battery types across the three variants, each with a different driving range. The R1S with the Standard battery (92.5kWh) has a claimed 434km driving range, the R1S Dual with Large battery (109.4kWh) extends that to 530km, while the Tri-Motor comes standard with the Max battery (141.5kWh) that has an impressive 597km of range.

It is worth noting, though, that those range claims are based on US EPA estimates, rather than either the WLTP or NEDC methods usually used.

Charging times vary depending on the type of charger used, in the US Tesla has given access to its network to other EV brands and the Rivian is available with a plug adaptor to use a Tesla charger. The R1S is capable of charging up to 220kW, which means it takes approximately 40 minutes to take the battery from 10 to 80 per cent. 

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. 

The R1S and R1T are Rivian’s first mass-produced cars, and it shows. It’s not all bad news by any stretch, but there are some major issues the brand will need to address in the future if it wants to succeed globally (or even just in the US). 

The biggest issue is the ride, which just doesn’t feel as well resolved as the more established brands that have been designing, developing and building cars for decades. The R1S isn’t bad to drive by any stretch, but the ride is too firm at times and it also lacks control and feels too soft at others. 

All R1S grades come standard with Air Suspension that has multiple levels of firmness and can adjust the ride height. However, in the ‘normal’ setting the ride feels too busy, with the heavy (3096kg) SUV skittering over the imperfections in the road rather than absorbing them. The problem is, if you adjust the suspension to the softer setting it lacks control and has a tendency to bounce over bigger bumps and take a few seconds to settle. This was particularly noticeable on LA’s concrete freeways, but it would be an issue on any road with undulations or joints.

But while the ride needs improvement, the R1S has strengths in other areas - namely performance. The Tri-motor AWD we sampled had immense punch from its three motors and it certainly felt like 633kW and 1495Nm was on tap. We didn’t test its acceleration claim officially, but any take-off could be made into a rapid one with just a squeeze of the accelerator pedal. 

The R1S is also capable of towing up to 3500kg, so it’s a strong and capable SUV too, rather than just a speedy EV.

Another strength is the regenerative braking system. There are multiple settings but we found the lowest regen was the best option, as it still provides powerful regen but is more progressive than the more powerful modes.

The R1S comes loaded with safety equipment across the range, including eight airbags, adaptive cruise control, autonomous emergency braking, blind spot monitoring, forward collision warning, lane departure warning, lane keeping assist and rear cross-traffic alert.

It also comes with what’s called the ‘Rivian Autonomy Platform’ that includes 11 cameras and 12 ultrasonic sensors for mild-autonomous functionality in specific circumstances, such as freeway driving or on well-marked roads. 

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.

Rivian offers a four-year/80,000km warranty for the R1S vehicle as a whole, as well as a separate battery pack and drivetrain specifically. The Standard battery is covered for eight years/190,000km while the Large and Max batteries are covered for eight years/240,000km.

As for servicing, Rivian uses an app-based system, which allows owners to schedule a service at any time via the app and then either have a Rivian technician come to your home for a small service or drop it off at a service centre if it’s a bigger job. The app is also connected to the car, so if the car’s own diagnostic system recognises a problem, it can prompt you to book a service proactively.
