Mitsubishi eK X EV vs Polestar 2

What's the difference?

And that’s the core takeaway from our time driving the Mitsubishi eK X EV – it’s a near-perfect tool for dealing with inner-urban congestion and tightly-packed city streets. After all, while cars have become progressively more bloated, our roads haven’t expanded in sympathy with that. The tiny measurements of the eK X EV and its slick and seamless electric powertrain allow drivers to flip that paradigm.

But even if Mitsubishi's Australian office chose to bring it here, it wouldn't be the first time the company has experimented with an ultra-compact EV in this country. Remember the i-MiEV from a decade ago? That too was a kei car EV with similar performance stats, however it languished in obscurity thanks to a high $48K price tag and a generally ho-hum offering.

By comparison, the eK X EV feels much more complete and better-equipped, though its price will need to be considerably sharper than the i-MiEV's if it's to convince would-be EV adopters to look away from the entry-level options from Chinese automakers like MG and BYD.

Will Mitsubishi take the plunge? It'll be chasing a niche within a niche if it does, but provided that audience uses the car within its urban-only design parameters, and provided Mitsubishi can offer it for a compelling price, the Japanese company could carve out a meaningful toehold in the EV space at the entry-level end of the spectrum.

The Polestar 2 Long range Single motor showcases a beautiful build and design. Not including the features from those optional packs just makes you focus on their individual price and devalues the relative affordability of the car compared to its competitors. The back seat isn't super passenger friendly when it comes to space, either. However, once you get used to its little quirks, it's a great car to get around in and the long driving range eases any range anxiety, which is often a cause for worry with EV ownership! My son loved the sunroof because it made him feel like he was in a spaceship, so it's a hit with the kids, too.

As a member of the uniquely-Japanese kei class of vehicles, the eK X EV has to fit within a very specific footprint of 3.4 metres long, 1.48 metres wide, and 2.0 metres tall.

The eK X pushes up right to those limits, measuring just 5.0mm shy of those length and width restrictions while stretching to 1655mm tall, and in order to maximise interior volume each face is almost perfectly vertical and all four corners are right-angles.

The end result is a very angular one-box hatchback, with the raked-back windscreen and bonnet giving the front half a somewhat wedge-shaped profile.

Is it a beauty queen? Not by any conventional standard – it’s more bricklike than beautiful – but like most kei cars its shape is driven by its function.

All four wheels are pushed right to each corner, minimising intrusion into passenger space, and the generous side and rear glass areas allow a great view of what’s around you – ideal for staying out of trouble on crowded Japanese city streets.

Another pragmatic design feature is the presence of roof rails – optional in Japan (¥27,500, or $311), but probably a good idea for those wanting to gain some more cargo capacity by bolting on a roof pod (which would certainly make the eK X EV look even more comically proportioned).

The P grade also brings a roof spoiler and black plastic wheel arch trims (both of which can also be had on the G spec as part of a ¥71,500/$810 bundle that includes the roof rails), which gives the stumpy eK X a smidge of SUV flavour.

And as far as style goes, it’s certainly cohesive with other members of the Mitsubishi showroom. The brand’s narrow-eyed headlamps and X-shaped grille motif translate well to the eK X’s nuggety bod, looking very much like if an Outlander’s visage was squished into a compact 1.48-metre wide cube.

The two-tone paint of our high-grade test vehicle looks modern and appealing (though it’s an expensive option at ¥82,500/$935), while single-tone paint jobs are also available.

However, if you’re a fan of artful vehicle design then the blocky and boxy eK X EV probably won’t excite your retinas.

The Polestar 2 has a more conventional design approach than some of its rivals but it maintains a futuristic EV vibe with its origami-like edges in the panelling and cool pixel LED lights at the front and rear.

It is not a large car and sits at 4606mm long, 1985mm wide and a low 1479mm high but that compact design makes it look sporty.

Expect a couple of grunts from the oldies (ahem) when exiting as ground clearance is 151mm at the front and 167mm at the rear.

The interior is pared back in true Scandinavian fashion but it's a nice to see some ethically-friendly design elements, like the vegan knit upholstery on the doors and dash and the Nappa leather is responsibly sourced. All of which makes an otherwise simple interior feel warm and inviting.

There is an overwhelming sense of the Polestar 2 being of a high-quality build. There are no squeaks or rattles, joinery is flush and the doors close with a soft thump.

However, the minor update still sees the dashboard headlined by a portrait-orientated iPad-looking 11.2-inch multimedia system. It seems at odds with the rest of the sleek design.

The panoramic sunroof creates a light-filled cabin and at certain times of the day, this makes it feel airy but underneath a blazing midday sun, you might miss having a sunblind for it.

While design might not be the eK X’s ace card, space efficiency absolutely is. 

Trust the Japanese to figure out how to make the best use of a compact volume – with compact apartments and ultra-dense cities being the norm for most Japanese people, it’s no surprise they’ve been able to extract the greatest utility possible from something the size of a kei car.

Those in the front seats get to enjoy some fairly cushy (though not super-supportive) chairs, with the driver’s seat being a little wider to cover the gap between it and the passenger seat.

Folding up the centre armrest also allows the driver to slide across to the left seat, perfect for getting out of a confined parking spot… or dates at the drive-in.

The steering column only adjusts for tilt and not reach, which is a bit of an ergonomics fail, but generally speaking there’s a surprising amount of room for ‘Western’ frames.

The manually-adjusted seats can slide a fair way back, headroom is substantial, outward vision is superb and, thanks to the narrowness of the eK X, literally everything is within arm’s reach.

The long shelf that spans the dash at mid-height is also a useful feature, an ideal perch for small items like keys, wallets, tissues and phones, while the cupholders are moulded into the dash itself and the climate control and shifter quadrant are housed in their own extension of the centre stack.

Below the climate controls, a bag hook is perfect for toting takeaway, purses or small grocery bags, and there’s some additional shelves and cubbies along with a USB-A, USB-C and 12-volt charger.

Peek under the passenger seat, and an under-seat stowage tray reveals itself, too. There’s even a pull-out compartment in the passenger door to house the owner’s manual. Everything in its right place.

Granted, with limited width there are some constraints on passenger space. The eK X’s rear bench only has room for two seats rather than three, but there’s enough shoulder room available to ensure it’s not as claustrophobic as you might think, and the rear bench is even mounted on sliding rails, has a reclinable backrest and offers more cushion length than the front seats.

With the seat slid all the way back there’s quite a lot of legroom for back seat passengers, while sliding it forward allows at least one piece of large luggage to sit in the boot while still giving enough space for passenger’s feet.

Other quality-of-life touches include some storage pockets high up on the front passenger’s backrest as well as bottle holders and cupholders integrated into the rear door cards, though, unlike the front seats, there’s no fold-down centre armrest or face-level air vents.

Mitsubishi doesn’t publish a cargo volume for the eK X EV, but the boot opening measures 1105mm wide and 875mm tall, with depth variable depending on the position of the sliding rear seat.

The rear seat backrests also fold down (though not flush with the boot floor), and supersized cargo can also be accommodated by reclining the front passenger seatback all the way so you can tote objects up to two metres long.

Under the boot’s floor hides an inflator kit and charge cable storage, though there’s no cargo blind.

The Polestar 2's cabin is generous up front with plenty of leg- and headroom to enjoy. You don't have to jostle for premium armrest position, either, which is nice given you still feel 'tucked' into the car.

A feeling that is enhanced by the solid, and rather tall, centre console that divides you from your co-pilot.

The electric front seats are delightfully comfortable with their padding and Nappa leather trim. Both feature four-way adjustable lumbar support and extendable under thigh support.

The heat and ventilation functions will ensure comfort, no matter the season but the ventilation system is quite loud.

In the rear, space is tight with my 168cm (5'6") height just fitting behind my driving position. The footwells seem cosy as well due to the limited under-seat space but the seats are fairly comfortable, if narrow.

However, the small door apertures in the rear and the narrow seats make it feel more suited as a four- than a five-seater.

Individual storage options are okay throughout the car with a couple of cupholders in each row, drink bottle holders in the front door storage bins, as well as a middle console and glove box.

There are two skinny shelves on either side of the centre console that would reasonably fit a wallet or phone and the rear also get two map pockets.

Amenities in the rear are enough to satisfy a mature occupant on a longer journey as the outboard seats feature a heat function and there are directional air vents, a fold down armrest and two USB-C ports.

Front occupants enjoy two USB-C ports and a wireless charging pad to charge their devices.

The rest of the technology is a bit awkward to use. The 11.2-inch touchscreen multimedia system is responsive to touch but you can't access a lot of basic information on it and I didn't like how the climate control is embedded in it as you have to touch the screen a few times to even see the controls.

The 12.3-inch digital instrument panel looks nice but isn't all that customisable. It takes a while to get used to how to access all of its functions, too.

It's easy to connect to the wired Apple CarPlay and there is wired Android Auto and in-built google apps, too.

The optioned Harman Kardon sound system with its 13 speakers means you can listen to your music as if you're in a private show performed by your favourite artist!

To round out the practicality of this sedan, the boot is large enough to carry your gear at 405L and the large compartment underneath the floor is super handy to store smaller items.

There is a panel that lifts up to make a cosier storage area, say if you only had a couple of bags of groceries you didn't want rolling around.

And because the Polestar 2 lacks an engine, there is frunk storage of 41L at the front which is perfect for any charging cables.

The compromise for getting all of this space is that you only get a tyre inflator repair kit, which is housed in the frunk storage area.

And lastly, having a powered tailgate is always a bonus but I miss having a good old-fashioned button on the boot lid to open it.

There are four variants available for the Polestar 2 and our test model is the Long range Single motor which costs $71,400, before on road costs and before any optional packs or paintwork options.

Relative to its nearest competitors, it seems like the most affordable but our model has been optioned with a few packs, which add a host of features that mostly come standard on its rivals.

Standard items include 19-inch alloy wheels, frameless side mirrors (very cool), pixel LED headlights with adaptive high beam and some decent technology, like four USB-C ports, an 11.2-inch touchscreen multimedia system and a 12.3-inch digital instrument panel. But more on tech later.

Our test model has the 'Pilot Pack' fitted, which tacks on $3500 and includes safety items like 'Emergency Stop Assist', which brings the car to a halt safely if the driver is unresponsive, and adaptive cruise control with 'Pilot Assist' (helps keep the car in its lane).

Our test model also has the 'Plus Pack' which adds luxury items like a panoramic sunroof, a premium Harman Kardon sound system, powered front seats with four-way lumbar support, extendable under-thigh support and net map pockets.

You'll also enjoy 'vegan knit' upholstery trims on the doors, a heated steering wheel, heated front and rear outboard seats, as well as a powered tailgate with foot sensor, all for an additional $6000.

But wait, we're not done. Our model also has the optional Nappa leather upholstery which includes a ventilation function on the front seats for an eye-watering $6000 extra.

So, when it's all done and dusted… this model will actually set you back $86,900, before on roads. That puts it on par with its rivals but it's a bit of a bugbear of mine when the pricing is set out like this as it makes it feel more expensive for some reason.

I like the fact that Polestar throws in the carpet mats and a charging cable but the paintwork options are a little expensive at $1500 and only one colour ('Magnesium') is included.

The eK X EV is powered by a single electric motor connected to the front wheels, and while all kei cars are limited by Japanese law to just 48kW, torque output has no such limitation.

Thanks to that loophole, and the generally torque-rich nature of an electric motor, the eK X EV produces peak torque of 195Nm, which is just 8.0Nm shy of the heavier petrol-powered Toyota Corolla.

A 20kWh lithium-ion battery pack supplies the motor with power, and is located under the vehicle’s floor. It’s a small battery, but it’s also a small car.

According to Mitsubishi, 20kWh is all most eK X EV drivers should need, but it’s about a third the size of typical EV’s battery these days.

The name of our model says it all, as it has a long range, single motor electric powertrain.

Coupled with a large 82kWh lithium-ion battery, which is a 4.0kWh increase from the previous model, the maximum power output is 220kW and 490Nm of torque, which is also up from the previous model.

The Polestar 2 is now rear-wheel drive, superceding the previous front-wheel drive model.

The regen braking isn't as strong as the previous model and although it is called 'one-pedal' braking on this system, it's not truly a one pedal driving experience.

You can change the strength levels from low to standard and I kept it in low for most of the week.

Our short (just under 30km) test drive was done entirely at urban speeds, with no significant highway component.

That plays into an electric car’s strengths, with minimal energy being used to fight aerodynamic and tyre drag, while the constant speeding up and slowing down for traffic and stop lights means a lot of energy gets put back into the battery via the regenerative braking system.

At the end of it, after using 23 percent of the battery (4.6kWh) to travel 28.3km, our average energy consumption measured in at 16.25kWh/100km, which is about par for a modern EV.

However, we were expecting a significantly lower result given the eK X EV weighs only 1080kg – half the weight of a Kia EV6 AWD. And Mitsubishi claims an average energy consumption of 12.4kWh/100km, with a city-only figure of just 10.0kWh/100km.

Couple that result with a 20kWh battery, and the eK X’s real-world range looks a lot more like 123km instead of the 180km WLTC Mitsubishi claims.

Granted, Tokyo traffic and streets aren’t a perfect analogue for Australian conditions, but there seems to be a big disconnect between the factory numbers and what we could achieve. Even for a city car, a circa-120km range may not be seen as sufficiently generous in Australia.

That said, there’s more than one way to deploy this car’s stored energy. You can use the eK X EV’s vehicle-to-load function to power household appliances through an adaptor, while another intriguing feature is the car’s Vehicle-to-Home (V2H) bi-directional charge capability.  

With V2H, a single connector can make the eK’s battery pack the source of power for an entire building. Useful in the event of a grid power outage, which is a real consideration for disaster-prone Japan.

As for regular charging, the eK X EV has a slightly oddball configuration. Open up the charge port flap on the driver-side flank and you’ll see an old-school Type 1 CCS connector positioned above a chunky CHAdeMO port.

While the latter is useful for bi-directional charging and has significant headroom for high-voltage fast charging, the Type 1 CCS port is probably less useful in Australia given most modern electric cars have moved to the more capable Type 2 CCS design.

If the eK X is to make any sense in Australia, that’s something that would likely need to be addressed along with its seemingly short legs.  

The Polestar 2 Long range Single motor has a great driving range of up to 655km (WLTP). Goodbye range anxiety!

It also has a Type 2 CCS charging port and can accept charging speeds of up to 205kW, which is 50kW more than the previous model, and that means you can hook up to an ultra-fast 350kW charger.

On DC you can expect to see a charge time of 28 minutes to get from 10 to 80 per cent. On an 11kW AC charger, expect to see that time jump to around eight-hours for a zero to 100 per cent charge.

The official energy consumption figure is 14.8kWh (WTLP) but my on-road average was 15.0kWh after a fair bit of open-road driving, which is a great result.

Kei cars are something of a unique experience to begin with, an electric one even more so. Besides those compact dimensions giving it the ultimate ability to cut through dense traffic, the addition of an electric powertrain endows it with the torque necessary to feel properly zippy around the city.

And by ‘zippy’, we’re not joking. With all of that torque being channelled through a pair of skinny eco tyres on the front axle, the eK X EV has little trouble squealing its tyres if you’ve got a heavy right foot.

It might be tiny but it moves with the feisty urgency of a Jack Russell, and thanks to its kerb weight of just over a tonne, it’s a nimble and light-footed thing.

It’s a shame the steering is so lifeless, though at least its fingertip-lightness makes easy work of lane changes, U-turns, and everything in-between.

There are three drive modes – 'Eco', 'Normal' and 'Sport', but they just change the throttle sensitivity and alter the strength of the regenerative braking.

Alongside this, a one-pedal accelerator model allows the bulk of speeding up and slowing down to be accomplished by modulating the throttle pedal, but you still need to move your foot to the brake in order to come to a complete halt.

We drove mainly in Normal mode without the one-pedal function activated, and the car felt smooth and easy-going.

Power delivery is linear, the regenerative braking feels natural, with no noticeable step between regen and mechanical braking, and there’s just a faint hum from the motor and inverter when power is being delivered or generated.

It’s difficult to form an opinion on the eK X EV’s suspension. Kei cars aren’t typically the best when it comes to ride comfort, handling, or any other discipline that requires suspension talent, but we can say that it was at least reasonably comfortable.

Take that assessment with a grain of salt, though. The perfectly-graded streets of central Tokyo are ultra-flattering to any car, and with little in the way of huge imperfections, weird camber or any other kind of challenging surface, we’d have to reserve suspension judgements until we can drive it on more varied roads.

That said, for its intended purpose of crushing short journeys through inner-city environments the eK X EV does a stellar job.

The Polestar 2 is a pretty conventional car to drive because an EV newbie will be comfortable behind the wheel… once they start driving it!

You see, there is no 'ignition' switch but so long as you have the key with you, you simply get in and shift into gear to 'start it' or get out and lock the car to 'turn it off'. It's weird and I'm not sure I will ever get used to it!

The motor has a lot of grunt and it's fun to put your foot down whenever you need to get up to speed or overtake. The power output is responsive and well-balanced with the rear-wheel drive delivering a sporty on-road experience.

If you're tackling winding roads or sharper corners, you can customise your steering responsiveness to 'light', 'standard' or 'firm' but remained on standard for most of the week. It's the best mode to handle stop-start running in town and highway cornering.

The Polestar 2 sits quite low to the ground and feels stable when you hit corners or the open-road. Although, the suspension feels on the firm side, which can make a bumpy road very noticeable.

Overall, the parking experience is good but the 360-degree view system is just too wiggy-woo for me to love it.

The images from the four cameras aren't well-stitched together and the angles seem to distort the overall image, too. It just looks confusing. So much so that you might not depend on it all that much.

When it comes to safety the Polestar 2 doesn't quite have the same level of standard features as its parent company Volvo is renowned for.

It has the necessities for a family car, but having to fork out extra for adaptive cruise control feels a bit cheeky.

The update sees some previously optional features come as standard now, such as rear cross-traffic alert, a 360-degree view camera and blind-spot monitoring.

The following safety features come as standard at this grade level - LED daytime running lights, forward collision warning, intelligent seat belt reminders, lane keeping assist, lane departure alert, traffic sign recognition, driver attention monitor, as well as front and rear parking sensors.

The Polestar 2 achieved a maximum five-star ANCAP safety rating from testing done in 2021 and has a total of eight airbags, including a drivers' knee airbag and front centre bag. 
The autonomous emergency braking with car, pedestrian and cyclist detection is operational from 4.0-85km/h (up to 205km/h for car detection).

If you need to fit a child seat or two (definitely not three), there are ISOFIX child seat mounts on the rear outboard seats and three top tethers.

The eK X EV is not yet offered in Australia, so at this point in time it’d be premature to put a number on ownership costs, maintenance, warranty coverage and things like that.

However, with a 20kWh battery it would cost somewhere between $4.20 and $7.00 for a full charge on household power depending on where you live and the kWh rate your energy provider charges you.

As always, those with solar generation and/or home battery storage could whittle those running costs down to practically nothing.

The ongoing costs for the Polestar 2 are fantastic because the servicing costs are complimentary for the first five-years or up to 100,000km, whichever occurs first!

Servicing intervals are reasonable at every two years or 30,000km, which is a usual term to see for an EV.

The normal car components are covered by a five-year/unlimited km warranty but the battery is covered by an eight-year or up to 160,000km warranty.
