BMW 5 Series vs Polestar 3

What's the difference?

There’s no getting around the i5 being a rather expensive offering. More than $150,000 to get into an electric sedan that’s not much faster than a hot hatch is a big ask, but there’s plenty to enjoy about the 5 Series.

Things like its heated leather seats shouldn’t be the reason you’re willing to spend so much on a sedan when a $50,000 hybrid SUV will score you the same, instead it’s the fact the 5 Series is a delight to drive and hasn’t lost the feeling of prestige the badge has earned over the last half a century.

In terms of value - if speed isn’t your focus and you’re less of a gadget-type-operator when looking at cars like this - the 520i has the style and comfort you’d need and at $100K less than the M60.

And in terms of large electric sedans, the i5 eDrive40 is cheaper than a Porsche Taycan (by a little) or an Audi e-Tron (by a lot). The Genesis G80 Electrified is the closest cheaper rival, by about $10K, or the less powerful Mercedes EQE is similarly priced at $154,900.

Essentially, if you’re looking at a 5 Series, it might be worth considering if you really need it to be electric, but if so, there aren’t many alternatives in its category for the price.

With the kind of driving range, dynamics and comfort that could convince even the EV doubtful to give it a crack, the Polestar 3 – and specifically this Long Range Single Motor – feels like it was worth waiting for.

If you’ve watched other members of the BMW family go into a new generation within the last few years - the 3, 4 and 7 Series particularly, you won’t be too surprised by what you see here. Especially with the latter, having seen the petrol variants look roughly the same as the electric ones.

BMW specifically made the petrol 520i and the i5 variants look similar for egalitarian purposes - to not disenfranchise 520i buyers who are still spending a fair chunk of cash but might not be ready to go EV.

That means all three variants score a mix of new and old. The kidney grille remains and isn’t as large as on the M3 or 4 Series, while the bonnet line following it and the ‘character line’ down the car’s side also remain. And yes, the Hoffmeister kink where the C-pillar meets the passenger window’s lower corner is still there.

On that C-pillar though is a ‘5’ stamped into the bodywork, new to this generation, while the front grille as mentioned has a glowing light surround - the brand’s ‘Iconic Glow’ already seen on the 7 Series.

Overall, thanks to being slightly larger in every dimension, the new 5 is starting to look bigger than a 7 Series from a little while ago. And that’s because it is - its body is overall longer than an E65 7 Series from the mid-2000s.

It’s 5060mm long 1900mm wide, 1515mm tall (97mm longer, 32mm wider, and 36mm taller). Its wheelbase is 20mm longer too at 2995mm. 

I think the Polestar 3 looks great – big, but not looming, and still somehow svelte enough to look sporty.

The brand takes a unique approach to marrying design and aerodynamics, with a lip at the edge of the bonnet that allows for airflow. But it doesn't look like a purely functional element.

Instead it accentuates what Volvo would call the 'Thor's Hammer' (but I think Polestar calls them 'Twin Blade') headlights, which are mirrored below with black venting.

In fact, looking at the 3 front-on is a bit like looking into a reflection in a crystal-clear lake, with the lighting signature perfectly reflected in the lower half of the front end.

If it sounds like I'm waxing lyrical, it's because I am. I think the Polestar 3 is among the best looking vehicles in its segment and one of the better looking SUVs, period.

Inside, though, it's a study in minimalism, which while very neat and tidy, makes it feel a little less luxe than you might expect from a vehicle at this price point. In fact, at a quick glance, it doesn't look that far removed from the relatively cheap-as-chips MG4's cabin.

The materials are thoughtful and lovely, though. Leather-like materials are used sparingly, replaced by what Polestar calls "Bio-Attributed MicroTech Charcoal with Repurposed Aluminium Deco". A far easier way to describe it, though, would be as reminiscent of a wetsuit.

Elsewhere, it's a fairly pared-back affair, with just the huge portrait-style central screen and the landscape driver screen grabbing your attention. Dig deeper, and there are some really nice, gentle details, like the ambient interior lighting that illuminates a little strip along the door panel, including the Bowers & Wilkins logo. A similar line of light spans the entire dash, too.

And I love the metallic-look panel along the dash which, one can only assume, is the 'Repurposed Aluminium Deco'.

A longer wheelbase means more space inside, where the 5 Series also still looks fairly familiar to those who have spent any significant time in a recent model BMW.

BMW has historically been pretty bang-on with ergonomics, and the new-gen 5 does a good job of sticking to that. Comfortable sports seats and quality feel for the materials on touch points mean the 5 Series feels nice to be in, and relatively restrained interior design for a somewhat luxurious car means it looks nice too.

It’s let down only by a couple of things - its multimedia screen and Operating System 8.5 is a little less simple to use now, and requires more touching the screen than previous iDrive systems, rendering the scroll wheel less useful.

The BMW Interaction Bar too is a little tricky to see controls on, as well as lacking physical feedback for using controls. Vent flow controls are digital sliders on the Bar, while vent direction is controlled by an unusual ‘joystick’ style control nearby.

The rear seat is plenty spacious, as you’d expect from a large sedan, with climate controls and ports for charging devices in the rear.

Polestar has done a solid job of disguising the dimensions of the Polestar 3, because while it looks sleek and sporty it's still a big boat, stretching a sizeable 4900mm in length, 1968mm in width and 1618mm in height.

That size is most noticeable in the back seat, which is properly cavernous, helped further by a fully flat floor which lends even more airiness. Sitting behind my own 175cm driving position there's plenty of headroom and tons of knee room, giving the Polestar 3 official adult-friendly status.

The ISOFIX attachment points are located beneath two pop-off plastic covers, which makes fitting a child-seat base super easy. This is something I wouldn't have cared about at all exactly 22 weeks ago, but now I care a lot, and this was among the fastest and easiest systems I've used.

Happily, there is no major back seat compromise, either. The pews are comfortable and supportive, with the window seats separated by a pull-down divider home to two pop-out cupholders.

There are twin USB ports for rear-seat riders, too, as well as air vents with temperature controls, and – thanks to that Plus Pack – rear seat heating.

There's storage aplenty, too, with a total 597 litres in the boot with the rear seats in place, and 1411 litres with them folded flat, including a handy 90-litre hidden storage spot under the boot floor. Up front, there's a soft-bag-ready 32-litre frunk.

I'm going to get this out of the way early. I am a touch surprised with the pricing on the Polestar 3 range.

With Tesla having now stepped on a million metaphorical rakes, and with a leader now slightly less popular than actual skunk musk, the stage seemed set for a rival brand to steal its crown, and its customers.

But I can't see too many making the leap from the $60K-$70K Tesla Model Y to the $118,420 asking price of the admittedly bigger Polestar 3 Long Range Single Motor - which is the cheapest way into the brand's large SUV.

Instead, Polestar will be taking aim at brand's like BMW, Mercedes-Benz, Porsche and Cadillac, leaving its Chinese corporate cousins (think Zeekr and Geely) to chip away at Tesla's market share.

So, premium product, then. But do you get premium stuff?

Ours gets the 20-inch 'aero' alloys, but you can spec those up to 22-inch wheels if you don't like your spine very much, along with Brembo brakes. Plus there's is LED lighting all around, a big glass roof and retractable door handles.

Inside, the Long Range gets heated front seats, triple-zone climate control, wireless device charging, and a big 14.5-inch central screen with Apple CarPlay and Android Auto (run by Google built-in) joined by a second 9.0-inch driver information screen above the steering wheel.

Our car was also equipped with what Polestar calls the 'Plus Pack', a cool $9.0K on top, which adds things like a 25-speaker Bowers & Wilkins for Polestar stereo (replacing the standard 10-speaker set-up) , a head-up display, heating for the rear seats, steering wheel and wiper blades as well as soft-close doors.

The as-tested price for our car, by the way, is $131,640, before on-road costs.

Despite BMW calling it ‘electrified’, the base 520i is only a mild hybrid so most wouldn’t realise unless they were told.

Its turbocharged 2.0-litre four cylinder puts out a modest 153kW and 330Nm, with power and torque sent to the rear wheels via an eight-speed automatic transmission.

BMW claims it’ll knock over the 0-100km/h sprint in 7.5 seconds, a few seconds too slow to blow anyone’s socks off.

The mid-spec eDrive40 has a little more kick to it, its rear-mounted electric motor capable of 250kW/430Nm and able to cut that time to 6.0 seconds.

It’s fitted with an 84kWh battery to draw its power from, the same as the 442kW/820Nm M60 with its all-wheel drive dual-motor setup.

The M-tuned i5 can hit 100km/h in a claimed 3.8 seconds. Bye bye socks, perhaps.

The  Long Range Single Motor tag hints at what's powering this Polestar 3, with a single, rear-axle mounted (so, rear-wheel drive) motor producing 220kW/490Nm and a fairly sedate sprint from zero to 100km/h of 7.8 seconds.

BMW claims the petrol 520i sips 6.7 litres per 100km from its 60-litre fuel tank, though we were unable to independently test any of the claimed figures on the launch day.

The base car has a theoretical range of 896km if it was possible to achieve the claimed fuel consumption figure for the duration of the whole tank - but it isn’t and realistically you could knock about 20-30 per cent off that, depending on how enthusiastically you drive.

In the i5 variants, the same 84kWh battery provides slightly different ranges due to the eDrive40 using 16.56kWh per 100km, and the M60 using 18kWh.

The eDrive40 has a claimed 550km maximum range, while the M60 has a 506km figure thanks to its extra motor and weight.

How far is far enough before you'd consider an EV? Because I've got to say, if I owned the Polestar 3, I'd probably have to plug it in once a week, if that.

A sizeable 111kWh lithium-ion battery provides the charge here, and unlocks a claimed WLTP driving range of 706km. Now, it's worth pointing out these numbers are rarely realistic. For example, WLTP testing is conducted with the climate control switched off, but a real-world result of 600km or more, depending on how you drive, is still a large number.

The battery is the same as in the dual-motor variant, but this RWD car is lighter and less powerful, and it has a lower top speed (180km/h), reducing its energy usage to 17.6kWh-20.3kWh/100km (from 19.6-21.8kWh/100km).

The Polestar 3 has a 400V architecture, meaning hyper-fast charging speeds are out of the question. Instead, it's capped at a maximum 250kW (still more than most public chargers in Australia can produce) which means a 10-80 per cent charge in 30 minutes.

At home, an 11kW charger will take more like 11 hours, or an estimated 16 hours using a regular 7.0kW wallbox.

According to Canstar Blue, the average price per kW for residential power in NSW at the moment is about $0.34. So, using my admittedly questionable maths skills, it would cost around $37 to take your Polestar 3 from empty to full at home.

For some cars, the list of features is what really separates the variants, but that’s not the case for the 5 Series. As is a bit of a BMW tradition, the drivetrains dictate the different trim levels and prices, and there are three fairly distinct flavours of 5 Series.

Starting at ground level, the 520i might at first seem like a bit of boring vanilla. Except it’s actually quite smooth and light vanilla.

There’s not a lot to write about when it comes to its drivetrain, but the lightness of its engine and petrol tank combo when compared to EV batteries and motors is refreshing, and makes for a quite dynamic rear-drive sedan.

Its 153kW and 330Nm is delivered smoothly enough with the mild hybrid assistance doing a little in helping responsiveness, but without intervening in the gearshifts it doesn’t feel particularly keen.

It lacks the ride comfort of the i5’s adaptive suspension, but it’s able to be driven in a spirited manner that belies its size and even, to some extent its 1725kg kerb weight. Chocolate sprinkles on the vanilla, if you like.

It’s not fast, but it feels nimble compared to its electric siblings and can carry a fair bit more speed through corners, after which there’s room to notice its rear-drive characteristics.

It’s especially noticeable after getting out of the 2130kg eDrive40, though the extra power from its 250kW/430Nm motor makes for some more spirited acceleration and a little more excitement when exiting a corner, especially if you’re aiming to double-check if it really is rear-wheel drive. There’s a little more than choc-topped vanilla going on here.

The steering is, like in the 520i, direct and responsive, though in most cases is probably best set to ‘comfort’ rather than ‘sport’ in its settings. 

The eDrive40 is rather comfortable and capable when barrelling through twisty backroads, and doesn’t feel out of hand for a five-metre-long sedan. It holds its weight well, and telegraphs when you might be approaching the limit quite sensibly.

When considering that, then, it’s impressive how brutally capable the 2305kg M60 is.

Here, we’re looking at a double-choc fudge with extra choc, and maybe some cookie dough in there for good measure. There’s a lot to like, but boy is it heavy.

It’s 580kg (or exactly half a Peugeot 208 GTi) heavier than the 520i, but it feels quick on its feet and its anti-roll seems to do a lot in terms of dynamics, the limiting factor really seems to be its tyres (which can and will squeal quite quickly to let you know when approaching said limit).

While you’ll need to take caution with how much speed you approach a corner with, you’re not going to lack acceleration on the other side, its all-wheel drive being less ‘fun’ but more efficient at getting you away from the bend than in the rear-drive eDrive40.

That adaptive suspension does also translate to a comfortable ride on relatively rough roads - only particularly bad bumps will reveal how much weight and pressure is being placed on each corner of the big sedan.

The Polestar 3 is that rarest of beasts – a big and sumptuous SUV that's genuinely engaging to drive.

This is going to sound odd given we're talking about 2.5-tonnes of Swedish metal but I reckon the fact it's not lightning-fast makes it more fun to drive. It somehow (and yes, this is a crazy thing to say) gives off Mazda MX-5 vibes, in the sense that, while some EVs feel utterly scientific in the way they accumulate speed, this rear-drive Polestar feels fun, perky and like you're actually driving it.

Don't get me wrong, there's more than enough power on offer here to get the 3 up and moving, especially the way it accelerates from low to mid speeds, but it's more than powerful enough to feel like you can push it a little bit harder without risking a visit to the undertaker.

The ride is good, too, leaning into its sporty nature without vibrating your eyeballs through suspensions stiffness, and the steering is direct and predictable. Speaking of which, you can dial up the sportiness of the accelerator (responsiveness) and steering (weight), too.

I also like the three-stage brake regeneration (off, medium and full 'one-pedal' driving) accessed through a permanent button at the base of the screen, and I prefer that it isn't as brutal as it can be in other vehicles. The cabin is also impressively quiet, though how much of that is owing to the Plus Pack's upgraded stereo arriving with active noise cancellation is a mystery.

There is no shortage of weight on board, though, and get too aggressive with the steering wheel and you'll get that disconcerting top-heavy tipping feeling so common with big SUVs.

I'm not convinced by the Polestar 3's software, either, with a couple of weird warnings popping up during my time with the car. The first warned that the driver assistance systems had failed, and told me to book a service, and the second even weirder issue is it liked to warn me there was "no valid key detected" despite it being in the centre console, and that "restart would not be possible".

Neither warning seemed accurate, to be fair, as the safety one went away on its own after a while and I had no problem starting the car.

The Polestar 3's safety story is a good one, and it begins with nine airbags covering all seating rows. The grille of the 3 is home to what the brand calls its 'SmartZone', which is where it hides the cameras, sensors and radars necessary for its AEB (with cyclist and pedestrian detection), cross-traffic alert with braking, blind spot alert with steer assist, lane departure warning and assist and active cruise control. The list goes on and on.

In the cabin, two infrared cameras monitor the driver, while four motion-sensing radars scan the rest of the interior for left-behind pets or children.

It scored the full five stars in Euro NCAP testing, and scored the highest child occupant protection rating of any passenger car tested by Euro NCAP in nine years.

BMW has a fairly industry-standard five-year/unlimited kilometre warranty on its new cars, while its electric car batteries are covered by an eight year/160,000km warranty.

For servicing, BMW offers numerous discounted packs and deals based on your preferences and desire to pay upfront.

For the 5 Series, a five-year/80,000km basic service package is $2400, though the i5 will have different needs and lower servicing costs not yet listed by the brand.

Another tick for the Polestar here. While I advocate for longer warranties (kudos to brands like Nissan, MG and Mitsubishi), the 3's five-year, unlimited-kilometre warranty and eight-year, 160,000km battery warranty is on par with its premium competitors.

The first five years or 100,000km of servicing is on the house, too (it's required every two years or 30,000km after that) and five years' roadside assistance is thrown in, as well.
