Polestar 4 vs Mercedes-Benz E-Class

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.

The Mercedes-AMG E53 Hybrid 4Matic+ is a superb blend of high-tech hybrid muscle and cossetting top-end luxury. Value is competitive, it looks (and feels) the business, despite the conventional sedan configuration it’s surprisingly practical (except for the modest boot), fuel-efficiency is a key benefit and safety is stellar. The ownership proposition is okay for the category but that’s not top of mind when an enticing series of corners ranges into view. It’s an impressive package.

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.

At first glance the E53 passes as a flash-looking Mercedes-Benz E-Class running 20-inch rims, especially in the launch car’s rich ‘Patagonia Red’ finish.

But then, there’s something about the AMG sedan’s stance that sets it apart. Which makes sense because the front fenders are wider by 11mm on both sides (compared to the E-Class) to make room for a wider front track (increased by just over 30mm over the previous-generation E53).

Wheelbase has also increased by just over 20mm to almost 3.0m and the car’s more aggressive nose treatment enhances the distinctive look.

There’s the AMG-specific radiator trim with ‘Panamericana’-style vertical slats, the sleek dual-section headlights and a large lower inlet that directs air to an additional front intercooler as well as an external opening for a wheel-arch cooler.

In profile there’s barely a hard edge to be seen, although character lines in the bonnet and along the car’s flanks contribute to a taut surface treatment.

At the rear, horizontally-connected LED tail-lights feature a stylised Mercedes three-pointed star signature, then a rear apron housing a diffuser and twin double tailpipe ‘trims’ and a bootlid spoiler on the left and right round off a beautifully proportioned design.

Climbing inside means a trip to screen city with an upright digital display in front of the driver flanked by a large central screen to the left and an additional panel for the front passenger beyond that. It’s a lot.

But once you’re on top of all the glass surfaces, details like open pore grey ashwood trim on the lower console come into focus, as do the brushed metal accents, beautifully sculpted ‘Performance’ front sports seats (optionally fitted to our launch drive example), racy stainless steel pedal covers and the five spoke AMG performance steering wheel with configurable rotary buttons.

It’s a supremely luxurious and comfortable 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. 

At over 4.9m long, close to 2.1m wide and a little under 1.5m tall, with a 2961mm wheelbase, the new E53 is a substantial car and feels it on the inside.

Plenty of breathing space for the driver and front passenger thanks in part to the away slope of the screen-dominated dash.

Generous storage, too, with large door bins including enough space for big bottles, a deep lidded box between the seats (which doubles as a centre armrest), a generous glove box and two cupholders under a sliding top at the front of the centre console. 

Hit the second row, and sitting behind the driver’s seat, set for my 183cm position, I have plenty of head and legroom, with enough shoulder space for three adults on short journeys. A trio of up to mid-teenage kids will be fine for a road trip.

Storage is pretty handy as well with hefty door bins and two pop-out cupholders in the fold-down centre armrest. No map pockets on the back of the (optional) Performance front seats, though.

Four-zone climate control means there’s individual temperature control for each side of the back seat, with adjustable vents at the back of the front centre console and trailing edge of the B-pillars. Very civilised.

Power and connectivity runs to three USB-C outlets and a wireless device charging pad in the front.

Thanks to the traction battery under its floor, boot volume is restricted to 370 litres (compared to 540L in the conventional E-Class sedan), although there are bag hooks, tie-down anchors and the 60/40 split-folding rear seat is able to liberate more space.

No spare tyre of any description, just a repair/inflator kit, which might make sense for automotive designers and engineers trying to maximise space and reduce weight, but doesn’t make sense for an owner stranded on the side of the road with an unrepairable puncture.

Priced at $199,900, before on-road costs, the Mercedes-AMG E53 Hybrid 4Matic+ lines up against an interesting mix of internal combustion, hybrid and pure-EV contenders, the most closely aligned on spec and price being the BMW M4 M Competition xDrive ($201,300), Lexus LS500h F Sport ($199,250) and Porsche Taycan 4 Cross Turismo ($197,400).

And as you’d expect for a performance sedan on the cusp of $200K the standard equipment list is long. Aside from the performance and safety tech we’ll get to shortly, the E53 features four-zone automatic climate control, 17-speaker Burmester surround sound audio (including digital radio), Nappa leather trim (including the steering wheel) and the ‘MBUX Superscreen’ display consisting of three screens - 14.4-inch central media, 12.3-inch instrument/info for the driver and 12.3-inch for the front passenger.

You can also tick off the box on Android Auto, Apple CarPlay and Bluetooth connectivity, plus the power front seats (with memory) are heated.

There’s also a head-up display, panoramic sliding sunroof, ambient lighting, keyless entry and start, built-in nav, a 360-degree virtual top-down camera view, LED exterior lighting and 20-inch alloy rims. 

There’s more, but you get the idea. This car is loaded with included features that help it match or better its diverse competitive set.

There are four optional AMG packages available - The ‘Night Package’ ($3000) which includes aero-influenced body elements, special rims and more. The ‘Carbon Fibre Package’ ($6000), featuring a range of carbon bits including the exterior mirror caps, bootlid spoiler and interior pieces like the centre console and steering wheel. A ‘Performance Seat Package’ ($5000), which unsurprisingly focuses on racier front seats with integrated headrests. And the ‘Energizing Package Plus’ ($5300) adds ‘multicontour’ front seats that are heated (as are the centre console lid and door armrests) and individual fragrance for the interior, as well as ionisation of the cabin air.

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.

The E53 is powered by a 3.0-litre, turbo-petrol, in-line six-cylinder engine working in concert with an electric motor housed within the car’s nine-speed (torque-converter) automatic transmission. 

Drive goes to all four wheels via an electro-mechanically controlled clutch distributing power between the front and rear axles.

Engine performance is up by around 10kW compared to the previous E53 thanks to software upgrades, a new twin-scroll turbo with higher boost pressure (1.5 bar vs 1.1 bar) as well as additional front and wheel-arch intercoolers. 

The engine alone produces 330kW/560Nm while the permanently excited synchronous motor chips in with a solid 120kW/480Nm for overall outputs of 450kW/750Nm.

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.

The E53’s official combined cycle (urban/extra-urban) fuel figure is 1.7L/100km, a spectacularly frugal number for such a high-performance machine. But it’s worth noting it’s predicated on the drive battery being constantly and completely recharged.

Speaking of which, the 28.6kWh, 400-volt traction battery is housed at the rear of the car under the boot floor. It delivers a claimed EV-only range of up to 100km, although that will diminish dramatically if you decide to push up towards the car’s pure-electric top speed of 140km/h.

Important to note the battery’s 21kWh ‘day-to-day’ capacity, designed to keep charge in reserve for any required ‘high-performance boosts’.

An 11kW AC charger is onboard with regenerative braking also harvesting energy, the car automatically selecting the level of recuperation power in line with traffic conditions.

In pure EV mode you can also manually adjust regen through four levels via the steering wheel-mounted transmission shift paddles. 

Auto stop/start for the engine is standard and 98 RON premium unleaded is recommended, although 95 RON is okay at a pinch.

The E53’s official fuel consumption figure and 50-litre tank capacity translate to a range approaching 3000km! But to bring that down to earth somewhat, on the launch drive program, covering urban and mostly highway running, we saw a (dash indicated) average of 6.4L/100km, which equates to a more realistic, but still lengthy, 780km between fills.

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. 

If you’re lining up for a Mercedes-AMG you want an optimal blend of luxury and performance and the E53 Hybrid 4Matic+ nails that delicate balance.

With 450kW (that’s 612hp!) and 750Nm under your right foot, engaging ‘Race Start’, pushing the accelerator to the floor and letting the car do its thing will result in 0-100km/h acceleration in 3.8 seconds. The fat band of mid-range torque is so satisfying to lean into.

Induction, engine and exhaust sounds combine to produce a suitably gruff soundtrack with the hybrid powertrain operating seamlessly. Hit your preferred track day or tempt legal fate and you can explore the car’s claimed (governed) maximum velocity of 280km/h. 

The nine-speed auto is slick and manual changes using the wheel mounted paddles are rapid.  In normal conditions the AWD system is biased to the rear and an electric rear locking diff helps keep things under control if you decide to get the bit between your teeth on a twisting drive.

A chunky brace links the front suspension strut mounts and the car feels predictable and stable in enthusiastic cornering. Rubber is Michelin Pilot Sport 4S (245/35 fr / 275/30 rr) which grips with satisfying determination but does make its rumbling presence felt on anything approaching a coarse chip surface (despite the car’s standard acoustic glass).

Speed-sensitive power-steering delivers accuracy and good road feel without any jitters, the standard active rear-axle steering playing its part. The ‘turning point’ is 100km/h with the rear wheels subtly turning in the opposite direction to the fronts up to that speed and in the same direction beyond it.

‘AMG Ride Control’ combines steel spring suspension (strut front, multi-link rear) with adaptive adjustable damping for the choice of ‘Comfort’, ‘Sport’ and ‘Sport+’ settings. Comfort is the pick for B-road running on typically uneven surfaces. The optional ‘Performance’ sports front seats are comfortable and grippy in equal measure. 

Braking is by ventilated composite rotors all around, with beefy four-piston fixed calipers up front. An electro-mechanical brake booster is designed to combine electrical recuperation with the hydraulic brake for more frequent and efficient energy harvesting over a longer period of time. The pedal feels firm and progressive with smooth initial bite. 

All around vision is good for a conventional sedan with a quality reversing camera, 360-degree overhead view and front and rear parking sensors helping massively with parking duties. That said, a 12.5m turning circle isn’t tiny.

The Mercedes-AMG E53 Hybrid 4Matic+ hasn’t been assessed by ANCAP or Euro NCAP, but that doesn’t mean it comes up short in terms of crash-avoidance and passive safety tech.

It features a comprehensive suite of ‘Advanced Driver Assistance Systems’ (ADAS) features including ‘Active Brake Assist’ (Merc-speak for AEB), adaptive cruise control, blind-spot monitoring, lane-change and lane-keeping assist, front and rear cross-traffic alert, traffic sign recognition, driver attention monitoring, adaptive high-beam, ‘Park Assist’ (including front and rear parking sensors) and tyre pressure monitoring.

And if an impact is unavoidable the airbag count runs to 11 - dual front, front and rear side, full-length side curtains, driver and front passenger knee and a front centre bag.

As the name implies, ‘Auto Emergency Call’ will contact emergency services after a collision and there’s even the obligatory Mercedes first aid kit and high-vis vests. 

There are three top tethers for child seats or baby capsules across the rear seat with ISOFIX anchors on the two outer rear positions.

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.

The Mercedes-AMG E53 Hybrid 4Matic+ is covered by a five-year/unlimited km warranty with the high-voltage battery covered for eight years/160,000km. Those terms match the key players in the premium and luxury parts of the market.

Mercedes-Benz ‘Road Care’ assistance is included for the duration of the main vehicle warranty. 

Maintenance is recommended every 12 months/25,000km, with service plans offered across three- ($4110), four- ($5410) and five-year ($7570) periods. That’s an average of around $1350 for the first two and $1500 for the last one. That added powertrain complexity obviously has an impact in the workshop.
