Polestar 3 vs Mercedes-Benz GLE300

What's the difference?

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.

Whether you like Coupe SUVs or not is an entirely subjective matter, but there’s no denying the GLE 53 is a tech and spec showcase – some of the best Mercedes has to offer. If you can get past its relatively enormous dimensions and naturally compromised visibility – it’s even a hoot to drive.

The significant proportion of GLE consumers who are picking one of these over the regular version will be pleased with its many improvements. We’ll know more about how its price and specification lines up against primary rivals closer to its Australian launch date, so stay tuned.

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'.

The GLE Coupe has improved so much in its looks it’s easy to see when it came to the second-generation GLE underpinnings, Benz had it planned from the beginning.

It looks mean, especially the 53 with its giant toothy grille. The stance is low and wide for an SUV, and I’m especially a fan of the much more resolved rear end.

It’s less bulbous and frumpy, more slick and menacing, rounded out nicely by the flick of a lip spoiler jutting out the rear.

You might think proportionally, the very idea of a coupe SUV is silly, and there’s no denying that, but then, you and I might not be the target audience.

That audience is someone looking for an avant-garde take on what a sports car actually looks like. They will be pleased – I’d say its even more resolved than BMW’s X Coupes and a little less science-fiction than Audi’s Q8. The incoming Coupe version of the Porsche Cayenne will be a real challenger.

The presence the GLE Coupe exudes extends to the inside, where there’s plenty of Mercedes wow factor. Level what you might at the brand’s use of silver fittings and flat dual-screen set-up, there’s no denying Benz offers an interior entirely unlike its competition.

The GLE has one of the best of the recent Benz interiors, too. I love the way the big dual-screen set-up is framed in a 'leather'-clad bay of vents.

I also like the real wood trim on our test car which runs across the dash and flows into the doors, and of course the wholly unnecessary vent-overload (becoming a Benz signature) pride of place in the centre of the dash.

It’s complemented by the tape-deck style silver switches for the climate controls which protrudes underneath.

The materials are great, with Artico trim running down the centre console, and across each doorcard. Almost every surface you’ll reasonably come into contact with is soft, and the commitment to real metals and wood is admirable.

Other highlights include the comfortable seats (with heating which extends into the armrests!) and AMG wheel which is flashy and aggressive, well suited to such a gratuitous vehicle.

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.

Naturally, the entire idea of shaving a solid bit of roof off of an SUV is going to compromise the amount of ‘practicality’ you get from such a large footprint.

Those compromises are not only there, but they are quite obvious. The sheer height of the GLE makes peering over the edge of the bonnet difficult for parking, and the sloped roofline causes the A-pillar to eat quite a bit of your field of vision.

As you might imagine, it’s genuinely difficult to see much out of the back of the GLE Coupe. I caught myself continually adjusting the rear vision mirror – as though somehow it would grant me more vision out of the letterbox rear window.

While front passengers get away with plenty of room, rear passengers are a little harder done by. This is again, largely due to the roof pillar, which eats into headroom and gives the cabin a claustrophobic feel.

Thankfully, legroom is fantastic (largely due to that massive GLE platform), the trim is all just as good as it is in the front seats, and the back of the centre console gets its own set of climate controls, adjustable air vents and USB-C power outlets.

I’d hardly say there’s an abundance of bottle holders for occupants, but there are a few. They aren’t big or packaged in ideal locations, but you’ll be able to get away with four 300ml containers in the front and four in the rear.

The boot has been re-worked from the GLE Coupe’s predecessor, there’s five extra litres on tap, for a total of 655 litres (VDA) – so it’s far from useless, but still down significantly from the full size GLE which has a massive 825L of space.

Benz has made the boot more useful, too, lowering the sill by 60mm for easier access.

There’s no dancing around the fact that the GLE Coupe is a niche, gratuitous product, targeted at a well-off consumer.

We don’t know what the pricing will be for the Australian range yet – and we won’t for a few months. But what we do know is Mercedes-Benz will only bring two highly specified variants to our market for the launch.

Those two will be the AMG-tuned GLE 53 which we were able to test at the launch, and a slightly lesser specified GLE 450.

Expect tall pricing, north of the wagon bodied GLE 450 ($111,341) for the 450 Coupe and outgoing GLE 43 Coupe ($145,829) for the GLE 53 Coupe.

The GLE Coupe will go into battle against the new BMW X6 (from $121,900) and Porsche Cayenne (from $116,600) and Audi Q8 ($128,900)

Standard features, as with the rest of the second-generation GLE range will be pretty good. We don’t know exactly what Australian-specified vehicles will get, but the GLE 53 as tested in Europe came with an extensive list of items.

You can expect all variants to get 20- to 22-inch alloys, electric tailgates, LED headlights, and Benz’ signature ‘Artico’ faux leather interior trim. The 53 also had a swish fully RGB adjustable interior ambient lighting suite and real wood in the dash. Very nice.

All GLE Coupes will have the impressive MBUX (I’m told it’s said “em bee you ex”, not “em bucks”) digital dash and multimedia suite, consisting of two 12.3-inch screens, one a digital dash, the other a multimedia screen.

The flashy setup also supports Apple CarPlay and Android auto as well as the usual connectivity via Bluetooth and packs several USB C outlets alongside Aux and USB 2.0. Our test 53 had a head-up display, too.

Mercedes’ built-in assistant (summoned by uttering 'Hey Mercedes') has perhaps the best native voice recognition on the market in terms of its accuracy and what it can do.

You can do things like adjust air conditioning, open the sunroof shade (oh yes, the GLE comes with a panoramic sunroof, too), and even find your specific music tracks via internet radio.

Then there’s the built in nav suite which is also one of the better ones on the market, featuring some very cool innovations.

The system will switch to the forward-facing camera when approaching an intersection and show you where to exit using augmented reality. Neat.

The 53’s system is also uniquely adjustable with AMG-specific themes and modes for the dash cluster, setting it apart from the lesser GLE 450 when it arrives.

It’s safe to assume there will be an extensive options list, including the 'E-Active Body Control' system (a $13,000 option on the wagon version) which uses cameras to detect road quality and optimize the air suspension system to suit. It also leans into corners. We’re keen to test it when it becomes available on the GLE 450.

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.

Australia will only get one engine in the GLE Coupe – a 3.0-litre 48-volt mild-hybrid in-line six-cylinder twin-turbo petrol.

There will be two states of tune. The 450 will be able to make use of 270kW/500Nm, while the AMG-spec GLE 53 we were able to drive at the launch has more power still (thanks to extra hybrid augmentation on the turbo) for a total of 320kW/520Nm.

For a quick comparison, the single-variant Q8 produces 250kW/500Nm from a twin-turbo V6, while the equivalent X6 – the M40i packs a 3.0-litre twin-turbo in-line six to make 250kW/450Nm.

The GLE 53 has a nine-speed auto transmission which is specially tuned by AMG to go with the expanded list of available drive modes. All Australian GLE Coupes will be all-wheel drive via a permanently active '4Matic+' system.

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.

The claimed combined cycle fuel consumption figure for the GLE 53 Coupe is 9.3L/100km, and while that’s not bad for something this heavy – keep in mind it’s an NEDC figure and not the widely-used WLTP figure so it could be a bit different by the time the GLE Coupe launches here.

Regardless, the fuel consumption is helped along by the abundance of ratios in the transmission and 48-volt mild-hybrid additions which help to remove inefficiencies from the drivetrain.

Our sweet but brief drive route in the Austrian Alps was not a fair reflection of fuel consumption, so we don’t have a real-world figure for you yet.

Expect the GLE 53 to require premium 98 RON unleaded petrol to fill its 65-litre fuel tank.

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 resurgence of the in-line six engine is a glorious thing, and it makes the GLE 53 quite a fun, if chunky, unit to drive.

Acceleration is urgent thanks to the pre-spooled first-stage turbo, and the transmission flicks through the gears like there’s nothing to it.

It’s perhaps not as 'smart' on the downshifts as competitor transmissions from Audi or Porsche, although Mercedes was keen to point out this will get better over time as the car’s computer 'learns' your driving characteristics.

Thankfully though, unless you’re in 'Eco' mode, the GLE 53 does a great job of letting you ride each gear out, giving you that signature in-line six sensation of an entire revolution range of relatively even torque distribution – a characteristic which Mercedes has gone to pains to perfect on a turbocharged engine.

This has the result of letting you bask in the sound for precious extra seconds.

While not as furious as preceding V8s – it is distinct. It’s refined and rich, although more subdued than you might have come to expect from vehicles wearing the Affalterbach badge.

I’m a fan. It’s an engine befitting a more refined sports machine than a garish statement.

The AMG suspension tune was great, too, keeping the massive Coupe truly under control in the corners, while soaking up bumps (which we’ll admit, there were few of on Austria’s immaculate roads).

It was interesting to read colleague Matt Campbell found the standard suspension less than impressive on the regular SUV-shaped variants, so we’ll see what the more basic set-up on the 450 is like at the Coupe’s launch.

I have no complaints about the steering, which proved to be responsive, smooth and accurate, while not erring too far on the heavy side, even in 'Sport' or 'Sport+' mode.

My main complaints lie with outward visibility and the sheer size of the GLE’s body. There were some nerve-wracking moments piloting it at speed around narrow streets with tall snow embankments encroaching.

And no matter how much I adjusted my seat and mirrors, the view out the back was particularly compromised.

We don’t know exactly how Australian cars will be specified yet, but expect the two GLE Coupes to come with flagship active features like high-speed auto emergency braking (AEB), lane departure warning with lane keep assist, blind spot monitoring, rear and front cross traffic alert, adaptive cruise control, 360 degree parking sensors and cameras, fully auto LED headlights, semi-autonomous parking, and driver attention alert.

The GLE has nine airbags and dual ISOFIX child seat mounting points in the outer rear seats.

Regular wagon bodied GLE class vehicles have maximum five-star ANCAP safety ratings as of 2019, and we’ll update you when we hear more about the Coupe variants.

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.

Mercedes continues with its three-year/unlimited kilometre warranty which is frustratingly standard across European premium car manufacturers in Australia– particularly its primary competitors, Audi and BMW. We doubt this will change any time soon.

Like VW Group competitors, though, Mercedes is now bundling in service costs in packages which can be tacked on to finance. The GLE requires servicing once a year or every 15,000km – we’ll update you on the cost of the packages closer to the Coupe’s local launch.
