Polestar 3 vs BMW Z Models

What's the difference?

The Polestar 3 Long Range Dual Motor with Performance Pack offers a lot of good stuff and in a segment filled with jellybean-on-wheels-designs, it looks great!

It’s large and comfortable enough for a family but the technology feels overworked and that hurts its functionality for me. So much so that at times it feels like you were driving a phone, rather than a car.

The Z4 didn’t make me feel like Peirce Brosnan’s 007. It’s way too serious – a proper gritty reboot. Maybe it’s meant for Daniel Craig. Either way, its brave design makes it one of the best-looking BMWs of recent memory, and it’s a tech- and comfort-fest that the Bavarian automaker should be proud of. I just wish it was a smidge more fun behind the wheel.

Where the Polestar 2 is mid-size, the Polestar 3 looks enormous but both feature what I like to refer to as Polestar minimalism. Crisp lines showcase the body without ever looking flashy.

There’s a distinct, growly edge to the Polestar 3 which its rivals lack with their pillowy designs and there’s no other word for it - it's hot.

While the thoughtfully sourced Nappa leather is a nice touch, it feels like virtue signalling to have the fact stencilled on the seats themselves. I don't need to know that it used 8.1kg of CO2e per square metre of material to produce, but it might float your boat.

This supple material is set against some lovely soft-touch knit fabrics that look great but easily pick up marks.

The Swedish Gold accents in the seatbelts and ambient lighting add some personality but the cabin looks too similar to its far more affordable sedan cousin for its price point.

The simply-styled but high-end looking interior won’t appeal to all, especially not when you’re considering the cabins of its flashier rivals but there is something beautiful in its minimalism.

The Z4 is a sight to behold. It’s brave, especially for a BMW, it even betrays the brand’s strongest styling pillars, making its own way with its more horizontal grille design, flat body and curved out rear.

It’s more than that, though. In black, this car looks sinister, brooding. The more you look at it, the more you notice tiny details - the scooped-out sides, or the way the entire rear seems to flick up into the integrated spoiler. I couldn’t get enough of staring at it – it manages to look even better with the roof down.

That’s probably when it hit me. To my eyes, at least, this is the most stunning BMW in years. Sure, the X7 is a sight to behold due to its sheer dimensions and borderline offensive grille, but the Z4 is the opposite. It’s subtle, it hides its details away in its silhouette.

It’s designer, Calvin Luk (an Australian no less), was inspired at least in part by the Z8 – another Brosnan bond car – and you can see the Fisker design reflected in the Z4’s low, flat grille and almost bulbous rear.

Inside, sadly, the Z4’s strong design doesn’t quite play out. There’s no wily Fisker touches here, just a standard set of BMW switchgear. While it all works well, it just dumbs down the Z4’s character.

The big, chunky steering wheel in particular is a let-down. It’s the same wheel that sits in the brand’s X5 SUV, and it feels right there, but not here in a convertible where you’re so close to the ground. A smaller wheel would not only suit this car better, it would make it feel just a smidge more alive. I miss the three-spoke M sport wheel from previous-generation BMW cars.

I do like the dash, which is seemly carved from rhomboid shapes - a theme that rolls into the doors, screens, and vents elegantly. I’m normally not a fan of gloss plastics and chrome touches, but in the Z4 they’re all tastefully applied.

The seats, too, are lovely. I’m not sure about the contrast bright-red leather our car came with, but they’re nice and close to the ground and have excellent trim that you seem to sink into just enough to be comfortable and sporty all at once.

It’s a slick place to be, I just wish it felt less like you were at the helm of an SUV and more like you were driving something that looks this damn good.

The best part of the Polestar 3 cabin is the space available for all occupants! What it lacks in a third row, it more than makes up for in legroom. So, if you have a couple of lanky teenagers in tow, they'll be happy.

Passenger access is excellent via the wide door apertures and 202mm ground clearance. The front seats offer the most comfort with their heat, ventilation and five-mode massage functions. However, the rear seats are ergonomic and well-padded, so even back there, you won't get fatigue on a longer journey.

Storage isn't as clever as it could be but you still get some solid options. There's a glove box (opened via the touchscreen) that can fit a manual; a middle console, under-shelf cubby that has an elastic tech pouch and a centre console that features two cupholders and a phone cradle.

In the rear you get small storage bins in each door, two cupholders in a fold-down centre armrest and two map pockets.

Other amenities in the rear are okay but not class-leading, especially not for a top-grade model. Back rowers get climate control, heated outboard seats, two USB-C ports and reading lights but that's about it. A few practical items like sun blinds and extra storage options would be good for a family SUV at this price point.

The boot offers a maximum of 597L of storage capacity available when all five seats are in use but that can be bumped up to 1411L when the rear row is folded. The rear row has a 60/40 split with a ski-port door that adds variation to the configuration.

A level loading space makes it an easy car to slide gear in and out of. The floor folds up to reveal a large storage pocket underneath which is a handy spot for when you only have a few items and don’t want them rolling around.

Like most EVs you don’t get a spare tyre, just a tyre repair kit but you do get a powered tailgate with kick function.

Now we come to what has become the least practical aspect of the cabin for my family and that's the technology.

There's no denying the 14.5-inch portrait-style multimedia touchscreen looks awesome. And when it works, it's great. But the emphasis is on 'when it works'.

If you’re familiar with the Volvo systems, you’ll figure it out, but if you’re not - expect to spend some quality one-on-one time with the system because this isn't a simple ‘get in and go’ set up. 

It's run by Android Automotive which means you get a whole bunch of Google apps built-in, like Maps, Assistant and Google Play. There are others, like YouTube, Spotify and Tidal as well. A software update later in the year should see Apple CarPlay enabled.

The system seems to have a few gremlins and there are sporadic moments where the touchscreen functionality stops, or menus/functions can't be accessed. As when the key fob battery was low and the wireless charging pad could not be enabled. A full reset on the system was required to restore functionality.

Outside of volume control, everything is accessed via the screen and that means you're one glitch away from not being able to use the vehicle optimally or open your glove box.

The 25-speaker Bowers & Wilkins surround sound system with Dolby Atmos is nice, though.

The Z4 is a convertible, so it’s naturally compromised on space. As far as convertibles go though, you’ll be hard pressed to find one you can fit more stuff into.

The Z4 is wide - the same width, in fact, as a 5 Series - and this carries into the cabin. There are only two seats, but those seats are wide, and occupants will find themselves with luxurious amounts of airspace for their arms, as well as excellent leather-trimmed and padded surfaces for landing elbows on.

Legroom is also great, as the seats have a surprising amount of rail-travel on them, so that even taller folk won’t struggle to fit their limbs in.

A genuinely impressive characteristic of the Z4 is much head room there it is. Despite its low-slung looks from the outside, the roof towers over my 182cm tall head when I’m inside, so this isn’t one of those convertibles that feels like braking too hard might simply decapitate those above six-foot tall.

In terms of storage areas you get some long but shallow trenches in the doors, a bay with connection ports and a Qi wireless charging pad under the air-conditioning controls, a glovebox (hey, not all convertibles have them) and a trick centre console that houses two deep cupholders inside.

There’s also a netted shelf behind the seats that could fit small bags, and given the length of the cabin, you could even fit laptops and the like behind the seats provided you haven’t used the full extent of the seat’s rearward movement.

The boot is deep, wide and long for a drop-top, and offers a total of 281-litres which is more than some popular hatchbacks. It even offers tie-down points and netting either side. To top it off, the fabric roof folds away into its own compartment, so the boot space is unaffected if you choose to drop the lid.

For a convertible – the Z4 is a practicality wizard.

The Z4 isn’t cheap, but it plays in a field of expensive Deutsche drop-tops. Our car was the mid-spec 30i which comes in at an MSRP of $104,900 (before on-road costs).

For that you’ll get a more highly tuned version of the base 20i’s four-cylinder turbocharged engine, producing 190kW/400Nm, 19-inch alloy wheels, M Sport brakes, Adaptive M suspension, and adaptive LED headlights.

That’s on top of the already impressively-specified 20i’s kit which includes dual 10.25-inch screens – one for the multimedia functions, the other as a digital dashboard, a head-up display, full Vernasca leather interior trim, auto-dimming rearview mirror, power adjustable and heated front seats with memory function, dual-zone climate control, 10-speaker 205W stereo, a Qi wireless charging pad, and adaptive cruise control as part of a marginally upgraded safety package (more on that in the safety section).

It’s a pretty plush set of equipment, although a challenging value proposition as the almost-as-well-equipped 20i starts from $84,900, a full $20k cheaper.

Rivals for this 30i model? You’ve got the soon-to-be-discontinued Mercedes-Benz SLC300 ($102,500), all-wheel drive Audi TT S quattro ($105,661), and, at a stretch, the entry-level Porsche Boxster ($122,960).

Of course, being a premium European car, there is an extensive options list. Our car was fitted with the excellent and probably-worth-the-money M Sport differential ($2400), as well as the rudely priced M seat belts (literally just the M pattern embroidered in - $560!) and interior ambient lighting package (lovely, perhaps not worth $550).

The Z4 is only offered in five colours, three of which – including our car’s Black Sapphire – come at a cost of $2000. The red interior, surprisingly, is a no-cost option.

If you’re keeping track that brings the car you’re looking at here to $110,410. Not cheap, and it doesn’t have six-cylinders - but given its other attributes explored later in this review, the fact that it still manages to undercut an entry-level Boxster is actually reasonable.

Our test model is a dual motor all-wheel-drive, with two 180kW permanent magnetic motors at each end of the vehicle. The Performance Pack adds a software upgrade which boosts the outputs (20kW/70Nm) and together this model produces up to 380kW of power and 910Nm of torque.

This gives you an impressive 0-100km/h sprint time of just 4.7-seconds and a top speed of 210km/h.

The chassis has been tuned with performance in mind and there is torque vectoring on the rear axle, as well as a rear motor disconnect clutch to save power at lower speeds.

Despite its massive outputs, I haven’t felt overwhelmed by the power but it has plenty of it to ensure a quick on-road experience. You certainly don’t feel like you can’t overtake!

Welcome to the age of ridiculously powered four-cylinder turbo engines. Despite a capacity of just 2.0-litres, the engine in the Z4 30i produces a whopping 190kW/400Nm.

That’s probably enough for a car this size. I’m keen to drive the six-cylinder, but surprisingly it seems to offer diminishing returns for extra cylinders offering a 60kW/100Nm power boost for an extra $20,000. Perhaps a six-cylinder is the way to go in a BMW, and given this car’s other seriously sporty attributes, it might be the only way to make it a bit more… fun. More on that in the driving section.

All Z4s are rear-wheel drive, using an eight-speed torque converter automatic. Sorry, no option for a manual this time around.

The Long Range Dual Motor with Performance Pack has a lithium ion battery with a large 111kWh of capacity but its claimed WLTP driving range is only up to 567km which positions it in the middle of its rivals.

This isn’t a bad driving range but I’d want an even longer one for a family SUV because it means less time at the charging stations with your kids on a road trip.

The Polestar 3 has a Type 2 CCS charging port and it can be connected to a rapid DC charger. It can accept up to 250kW on this type of system, which is excellent.

An 11kW AC or 50kW DC charger will take up to 11 hours or two and a half hours to charge, respectively.

Our test model has an official claimed WLTP energy consumption range between 21.9 to 23kWh/100km and after a mix of open and city driving we managed to hit an average of 20.4kWh, which is good for such a big EV.

It’s claimed that the Z4 will drink just 6.5 litres per 100 kilometres on the official combined cycle test, but I found that sticking my foot in occasionally resulted in a slightly more realistic sounding figure of 8.4L/100km.

That’s still a great fuel consumption number for a car like this, and perhaps one of the strongest benefits of having just four cylinders.

A discerning vehicle, the Z4 will drink nothing less than the best-quality 98RON unleaded to fill its 52-litre tank.

I have been a little surprised by the top-model grade this week. It’s got heaps of power and your tummy does a little leap when you really have to put your foot down but the strong regen braking and adjustable one-pedal function (up to two levels) take a long time to get used to and sometimes it just feels like it's champing at the bit but not in a fun, sports car way.

The Polestar 3 sits lower to the ground than some other large SUVs but it’s not as steady as I would expect in cornering. The adaptive suspension is adjustable depending on the drive mode you select but remains fairly firm and you feel the bigger bumps.

The visibility is great and none of the pillars are in the way from my driving position, the frameless side mirrors also add a wide view into your blind spots. 

The active noise cancelling tech means the cabin is delightfully quiet and it's very easy to chat with the back seat passengers. I’ve hated that you can’t ‘close’ the sunroof though because despite there being little to no heat, the constant sunlight is really annoying.

The 360-degree view camera system is high quality and despite a few fish-eye lens angles you can get, this is a very easy SUV to park.

My dad struggled with the concept of not turning the car on or off, and in his words "it just feels wrong!". This is a Polestar experience though that you get used to (eventually).

However, the aspect I struggled with is that you get two 'keys' - an easily lost key fob and a keycard (same size as a credit card).

You apparently need both to access the vehicle - the keycard to unlock/open the doors if the key fob proximity feature doesn't register and the key fob to actually drive.

Although, at a pinch the keycard is technically a second key and can be used to drive if the battery on the key fob runs out. Oh, did I mention you have to charge the key fob? It all seems a bit superfluous.

A car that looks this good better live up to the promise behind the wheel, right?

For the most part, the 30i does, but it’s a victim of its own performance credentials and luxuriousness.

See, a drop-top should be fun-packed, you should feel close to the road, connected. Sadly, a combination Z4’s excellent suspension and not-so-excellent SUV-like interior separates you too much from the surface below.

An advantage, of course, is the refinement on offer. The Z4 is easily one of the quietest, most refined convertibles I’ve ever driven, but it’s a little too insulated.

I can’t help but feel like it’s all business and no pleasure. It feels a little more like I should be cruising to work on the autobahn and a little less like I should be flinging it around corners on a tight B-road.

It feels almost wrong to drive it in a T-shirt. It’s serious and doesn’t want you to mess around, it wants you to wear a suit and tie.

This grand-tourer style feel is one that will keep a lot of buyers in the premium space happy, but I’m of the opinion that BMW will have that segment well and truly covered by the new 8 Series. If the budget allows.

Regardless, the 30i’s four-cyl engine feels like any six-cylinder would have a few years ago. It’s got a surge to it in the straights that’s quite satisfying, and it responds via the exhaust with an angry tone that makes it feel a little more alive, especially with the roof down.

This feeling was all helped along by our car’s M active differential which simply won’t let the fat tyres at the rear slide unless you’ve got high-speeds and loads of tarmac to play with – for better or worse.

The Z4 also has ‘variable sport steering’ which reacts to the car’s speed and position of the wheels to adjust the input ratio. It’s good when you’re at speed, but the weight and response of the steering can make the Z4 feel bigger than it actually is at lower speeds. 

The suspension is firm, and can be a little bouncy over rough surfaces, but seems well suited to the Z4’s chassis.

Other than those notable characteristics you’ll find that the Z4 is wonderfully tuned in terms of its inputs, everything is slick and smooth, suited perfectly for long meandering drives.

Convertibles and safety don’t often fall in the same sentence, unless its one where a concerned relative is trying to convince you not to buy one.

In any case, the Z4 benefits from four airbags (dual front and dual side), as well as the expected electronic stability controls. That optional M Sport differential will have the added bonus of preventing any unexpected slip and slide at the rear.

On the active side the Z4 gets ‘Driving Assistant’ which includes forward collision warning (FCW), lane departure warning (LDW), rear cross traffic alert (RCTA), and rear collision warning. The 30i grade also gets 'active cruise control with stop & go' which allows for full auto emergency braking (AEB) with pedestrian and cyclist detection. Not on the spec sheet, but apparently present in the car I drove was some form of traffic sign recognition (TSR) and lane keep assist (LKAS).

A nice high-res reversing camera displayed on the massive touchscreen is a welcome standard addition.

Considering the meagre safety specification of most convertible cars, the Z4 30i shines with a half-way decent active safety suite. But you can forget ISOFIX child-seat anchor points. There aren't any. 

Polestar offers the Polestar 3 with a five-year/unlimited warranty and the battery is covered by an eight-year or up to 160,000km warranty. You also get a free service plan for the first five years or up to 100,000km of ownership, whichever comes first.

Considering its position in the premium-end of the EV market, this is good value compared to its Euro rivals.

If recent quotes are anything to go by BMW is set to stick by its lacklustre three-year unlimited kilometre warranty, as it says its customers simply aren’t interested in five years (or longer) when it comes to warranty coverage.

It’s a shame, as even Volkswagen has upped its warranty to five years, and Mercedes has considered a 10-year coverage plan in the past.

In terms of servicing, there are two fixed-price plans available – the suspiciously cheap ‘Basic’ plan which comes at a cost of $1373 for five years (or $274.60 per year) and the more realistic-sounding ‘Plus’ which costs $3934 over five years (or $786.80 per year).

Like every other BMW, the Z4’s computer tells you when its service time: how often it needs maintenance will depend on how often – and how hard – you drive it.
