Mitsubishi eK X EV vs Nissan Ariya

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.

I can see how the Nissan Ariya would have changed the game if it launched in Australia back in 2022.

While it is a solid car that’s quiet, comfort-oriented and tech-heavy, there’s now little separating it from the competition apart from the fact it has a Nissan badge and a cracking aftersales package. This is disappointing as we’ve waited a long time for this car to arrive.

Note: CarsGuide attended this event as a guest of the manufacturer, with accomodation meals provided.

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.

Back when the Ariya was revealed, it started a new design language for Nissan, but five years later almost every model in the Japanese carmaker’s line-up has taken some element of this car’s design.

What this means is while the Ariya was unique, it now doesn’t stand out from the crowd as much as it once did. This doesn’t help given there are now so many competitors out there.

However, in person the exterior of this car is stunning. I’m particularly a fan of the two-tone copper paint available on the Advance+ and Evolve e-4orce.

At the front there is a slim and striking LED lighting set-up that stands out, plus the gloss black faux grille is an interesting take on the brand’s ‘V-Motion’ grille. It has illuminated sections that are only noticeable in dark conditions.

Around the side the Ariya appears to be a lot more coupe-like than you’d expect. There’s a body line that runs from the A-pillar all the way to the tailgate. It gives the car a floating roof effect, which is a current design trend.

Other notable design elements on the side include the charge flap on the passenger side front quarter panel, aero covers for the alloy wheels, and an extensive use of gloss black around the wheel arches and door sills. It’ll be interesting to see how the latter hold up in the long run.

At the back there isn’t a whole heap going on beyond the large rear spoiler, which is intricately designed and there to improve aerodynamics.

There’s also a full-width LED light bar for the tail-lights, which is sandwiched by a Nissan wordmark badge. These lighting set-ups are so common now that they’re a little cliche.

Inside, the Ariya is befitting of its flagship status for the Nissan brand. In the top-spec Evolve trim with the blue Nappa leather upholstery and suede dash highlights. I don’t think it pairs well with every exterior paint colour, but it still looks great.

This also isn’t to belittle the lesser trims. While they have darker interiors, this is likely more preferable for many buyers as they’re less out there. The materials, at least in the Advance+, are still at a high quality.

The steering wheel is leather-wrapped and feels buttery soft in the hand. While I loathe the fact there are gloss-black covers over the physical buttons on the steering wheel, it’s still a step in the right direction.

Ahead of the driver are dual 12.3-inch screens across the line-up. It took me a while to notice there’s a wave between the screens as it’s covered by the steering wheel rim. The touchscreen is incrementally closer so you can reach it more easily.

Another major element of the Ariya’s interior design is the centre console. In the Advance+ and Evolve it has electric sliding adjustment, allowing you to customise the position to your desire.

The use of the faux wood trim looks premium, especially because you don’t expect there to be haptic buttons on it. This helps for a clean, button-less look.

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.

This car is built on a dedicated electric architecture which theoretically gives it many benefits as there’s no space needed for a combustion engine, nor its transmission or driveline components.

While the Ariya benefits from this by pushing the wheels to the extremities, it underwhelms in others. More on this in a bit.

As standard the driver’s seat is mounted very high. I’m 182cm tall and in the seat's lowest position I was only a few centimetres off my hair tickling the roofliner. While this is nice from a forward visibility standpoint, I instinctively want to sit lower in the cabin.

Despite this, the front seats are deliciously comfortable. They offer plenty of electric adjustability, allowing you to find your desired seating position. Depending on the trim they’re heated and ventilated, which is a treat in fickle Melbourne weather.

As noted before, the steering wheel features physical buttons, which is a major plus. They’re clearly labelled and are easy to understand.

Ahead of the driver the digital instrument cluster is classic Nissan. There are a range of informative pages to cycle through, as well as two layouts to choose from. All of them look high-res.

Moving across, the touchscreen multimedia system is also a classic Nissan unit. Almost every Nissan model has a variation of this touchscreen now, which kind of makes the Ariya feel less special.

Thankfully however, the user interface is clear and easy to understand. It’s hard to get lost and even if you do, there are shortcut buttons on the side of the screen.

As standard there’s wireless Apple CarPlay, which is great if you have an iPhone and almost expected nowadays, however Android Auto is only offered in wired form only. This is disappointing from a high-tech flagship.

I appreciate there are haptic buttons for the climate control under the touchscreen. It’s much better than having these functions built into the touchscreen. However, the seat heating/ventilation and the steering wheel heating is in the touchscreen, but you can program it to an automatic mode so it’ll turn on and off with the climate control.

The haptic buttons extend onto the centre console which electrically slides in the Advance+ and Evolve. These ones are for the drive mode and ePedal selection.

Speaking of the centre console, it’s a big bulky unit but it barely offers any storage. Under the centre console lid there’s a wireless charger and a miniscule amount of storage. There’s also a tiny phone-sized slot at the front of the centre console, plus a 12V socket and some USB ports.

It’s disappointing Nissan hasn’t taken better advantage of the flat floor accommodated by the dedicated electric architecture. There’s open space between the driver and passenger, which makes it feel like you’re in dedicated recliners.

As a result of the paltry centre console storage, there are two gloveboxes. One on the passenger side and another in the centre. Both look like they’re sizeable, but that’s just the lid as the actual storage space is a fraction of this.

Moving to the second row I have a decent amount of legroom behind my own driving position. Toe room is negligible however and headroom suffers from the panoramic glass sunroof.

Despite this the second-row bench is still comfortable. It’s laid back, though there’s not much lateral support. This means in the bends you’ll be thrown into the door or into the centre of the car.

There continues to be a flat floor in the second row, plus a minimal hump in the rear bench means you could technically go three-up if you wanted. The limitation at this point is shoulder space.

In terms of amenities there are centre console-mounted air vents, USB-C ports, heated outboard seats (depending on the trim) and a fold-down armrest with cupholders. It’s fairly standard.

From the Advance trim and up there’s a standard hands-free power tailgate. This is handy if you’ve got your hands full.

For the boot space itself, it’s fine but not standout. Two-wheel-drive variants are notably better with 466L of boot space with the rear seats upright. The Evolve e-4orce only has 408L due to the rear electric motor.

As expected there’s no spare tyre at all across the line-up. Instead there’s a tyre repair kit under the boot floor.

No Ariya trim has a front boot.

The Nissan Ariya is launching in Australia with four trim levels – Engage, Advance, Advance+ and Evolve e-4orce.

Pricing starts from $55,840 before on-roads and extends to $71,840 before on-roads. This is more than top-selling rivals like the BYD Sealion 7 and Tesla Model Y. It’s more on par with the likes of the Kia EV5 and Zeekr 7X.

With the Ariya Engage at $55,840 before on-roads, you get 19-inch alloy wheels, LED headlights, dual 12.3-inch screens, wireless Apple CarPlay and wired Android Auto, a wireless phone charger, a six-speaker sound system, dual-zone climate control and charcoal fabric upholstery.

Stepping up to the Advance at $59,840 before on-roads brings a hands-free power tailgate, a 10-speaker Bose sound system, heated front seats and steering wheel, as well as black cloth and synthetic leather upholstery.

The Advance+ at $63,840 before on-roads gains a larger 87kWh battery pack as standard, plus a panoramic glass sunroof, a power sliding centre console, ventilated front seats, heated rear outboard seats, as well as black synthetic leather upholstery with suede inserts.

Lastly, the flagship Evolve e-4orce at $71,840 before on-roads gets an all-wheel drive set-up, 20-inch alloy wheels, adaptive high beams, a digital rear-view mirror, electric steering column adjustment and blue Nappa leather upholstery.

This is a generous spread of variants and while the pricing and equipment list doesn’t stand out from the crowd, none of the trims miss out on the basics.

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.

There are only two electric powertrain configurations available in Australia.

The Ariya Engage and Advance are powered by a single, front-mounted electric motor that produces 160kW of power and 300Nm of torque. The Advance+ bumps the power figure up to 178kW to compensate for the larger battery pack.

The flagship Evolve e-4orce is the only trim with all-wheel drive. It has a dual-motor set-up with total system outputs of 290kW and 600Nm. This trim is claimed to be able to do the 0-100km/h sprint in 5.6 seconds.

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.  

There are also two battery pack options in Australia.

The Ariya Engage and Advance come with a 63kWh lithium-ion battery with a WLTP claimed range of 385km. This isn’t much for a car that’s around $60,000.

The Advance+ and Evolve e-4orce, on the other hand, get a larger 87kWh lithium-ion battery. WLTP claimed range is 504km and 487km, respectively, which is much more like it for a vehicle of this size.

All variants have a Type 2 CCS combination charge port on the passenger side front quarter panel with a maximum DC charge rate of 130kW. At this rate this will see the battery charge from 10 to 80 per cent in 35 minutes.

AC charging is offered at rates up to 7.4kW on the Engage, Advance and Advance+ trims. 22kW AC charging is optional on the Advance+ and standard on the Evolve e-4orce.

However, thanks to a launch offer for the first 400 vehicles, all Ariyas are getting standard 22kW AC charging, even the ones that typically don’t get it at all. This is a cool offer and an interesting incentive if you are on the fence on actually buying one.

There’s also a free 22kW AC home charger provided as an additional launch offer. You’ll need to install this unit at your own expense.

For energy consumption it depends on the trim level. It ranges between 18.4 and 20.8kWh/100km. During our testing of the Advance+ we saw an average of 14.2kWh and the Evolve e-4orce we saw an average of 18.0kWh/100km. This would give a theoretical range of 613km and 483km, respectively.

It’s worth noting these average energy consumption figures were according to the trip computer and the driving was on higher speed roads on the outskirts of Melbourne.

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.

We only got to experience Ariya trim levels with the larger 87kWh battery pack at this launch. It’d be interesting to see how trims with the smaller battery pack fare from a comparative standpoint as they’re lighter but offer less range.

With the Ariya Advance+, it has a single electric motor that offers a decent amount of power and torque. It’s probably all that you’d ever need in everyday traffic.

However, it’s far from being a sporty offering – it’s more comfort-oriented – but when you push it, the limitations of it being front-wheel drive become apparent. Traction control cuts power as soon as the corners get too sharp, but thankfully it never feels like this car is out of line.

For more oomph, this is where the flagship Evolve e-4orce comes in with its dual-motor all-wheel-drive set-up. Although 290kW and 600Nm sounds like a lot, it doesn’t provide neck-snapping acceleration. Instead, acceleration intentionally ramps up incrementally to maintain a serene vibe in the cabin.

This isn’t to call this Ariya trim slow, though. It can do 0-100km/h in 5.6 seconds, which is far from a slouch. The way the power piles on though feels nice during rolling acceleration, making it a lovely tourer. If you do lean into the performance this trim offers however, be prepared to pay for it with a higher energy consumption.

There are multiple regenerative braking modes offered in the Ariya. ‘D’ is normal, ‘B’ exaggerates the effects, then ‘ePedal’ is the closest you get to a one-pedal driving mode. All the modes require you to press the brake pedal to come to a complete stop.

Thankfully, there’s no awkward interaction between the regen brakes and the traditional friction brakes. This helps make it feel like a regular car that just happens to be electric.

The steering changes its weight depending on the drive mode. Regardless of this, however, there is a direct feel through the wheel which is confidence-inspiring, especially out on the open road.

As standard the suspension set-up comprises MacPherson strut front and a multi-link rear across the line-up. With the smaller 18-inch wheels across the majority of the line-up there’s plenty of tyre sidewall to play around with, which makes the ride feel composed and comfortable. It balances the line between being too bouncy and too firm nicely.

The top-spec Evolve e-4orce with its larger 20-inch alloy wheels, however, has less tyre sidewall and as a result the ride is much busier. The effects are made worse when you load more people or weight into the car as it becomes very reactive to every road imperfection, especially large bumps.

Lastly in terms of noise, vibration and harshness levels, it’s extremely quiet in the cabin. This is surprising because the lack of a combustion engine typically makes other noises more apparent.

The Nissan Ariya has a five-star ANCAP safety rating based on testing conducted by Euro NCAP in 2022.

Standard safety equipment includes seven airbags, autonomous emergency braking (AEB), blind-spot monitoring, rear cross-traffic alert, lane-keeping assist, lane centring, adaptive cruise control, driver attention alert, front and rear parking sensors, as well as a reversing camera.

Stepping up to the Advance brings surround-view cameras. This is pretty standard on the safety front.

The AEB system is active from 5km/h and lane-keep assist is active from 60km/h.

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.

Like other Nissans, the Ariya is covered by a 10-year/300,000km warranty, providing you service at authorised Nissan service centres when required. If you don't, there's only five years of coverage.

The battery pack on the other hand is covered by an eight-year/160,000km warranty.

There’s also up to 10 years of roadside assistance if you service at authorised Nissan service centres.

Logbook servicing is required every 12 months or 20,000km, whichever comes first, and the first five services are capped at $299 each.

Overall this is a fairly compelling aftersales package, plus it helps that Nissan has a substantial dealer network around Australia.
