Mitsubishi eK X EV vs Toyota Yaris

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 Toyota Yaris is as much car as many people should really need, and it's a refreshing antidote to the largely unnecessary shift towards SUVs as the ‘default vehicle’.

In the case of the ZR grade, the pricing could understandably be a reason you might consider an SUV instead. There are plenty of options for a similar price.

The problem with an SUV though is it will likely be less efficient and, due to physics, less agile and fun to drive.

Given the price and the fact that a couple of features are missing, the ZR probably isn't the variant to go for, but the Yaris is an overall solid foundation for a very convincing hatchback.

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 Yaris’ best selling point could very well be its looks. While there are a lot of differences between the ZR and the bespoke GR Yaris hot hatch, they do look similar, especially from the rear.

Any small car like this is going to have an element of ‘cutesy’ about it, but the Yaris does well to look like a more sporting car than its rivals.

The grille is the only big design change Toyota made as part of its most recent update in early 2024. It's a new design that’s finished in partial dark chrome for the ZR.

At the rear, the ZR gets a spoiler above the rear window, helping it look a little more like its Gazoo Racing cousin, as does the block of black trim flanked by the tail-lights and the ‘Yaris’ and ‘ZR’ badges.

Even its front lower bumper would look reasonably at home on a more powerful car if the plastic trim at the sides had actual air vents rather than being closed off.

Inside, things are less exciting. The ZR’s interior seems plasticky and its grey cloth seats do nothing to make the space feel premium.

The ‘two-level’ look on the dash and the arrangement of the multimedia screen and climate controls below it feel outdated, but the cabin is (perhaps more importantly) clear and functional.

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.

For all its grey trim, the Yaris actually proves a very usable space for its size. The two front ‘sports’ seats are quite comfortable with decent bolstering.

The steering wheel is nicely shaped, and big clear buttons (like most of the cabin) mean controls for all the car’s functions are obvious.

The digital driver display is customisable in terms of its style, but the information you might need is easy to find and not distracting while you’re trying to concentrate on the road. The head-up display also helps there.

The physical climate control panel isn’t exactly ‘pretty’ but it’s infinitely better than needing to navigate through the screen above. 

That screen itself is also easy to use. Toyota’s multimedia systems can feel outdated but the upside is there aren't loads of submenus to get lost in.

Storage is well covered: two cupholders are out of the way of elbows, plus a little storage space behind that between the front seats. There’s a small space behind the gear shifter for a phone, a couple of small 'shelf' spaces above and in front of the passenger, and there are decently spacious door card places for water bottles and the like. 

In the second row, behind my own (178cm) seating position, ‘spacious’ is less applicable. It’s not surprising that the second row in a light hatch would be a little tight for an adult, but it’s not restrictive and some kindness from the front passengers could see the back seats become a comfy place for a sub-60-minute trip. 

There’s no centre armrest, but each door has a water bottle holder and the aforementioned storage spot between the front seats is accessible from the second row.

Behind the rear seats, there’s a 270-litre boot which is decent for its class. The non-hybrid Mazda2, for example, has 250L.

The boot floor can be lifted to sit flush with the seats when folded down, and underneath there is a space-saver spare tyre, which is a huge plus.

In the grand scheme of new-car pricing, $34,530 before on-road costs doesn’t sound like a lot of money. That’s how much the Yaris ZR is new.

But compared to other top-spec trims in rival models, it’s one of the most expensive in its class.

It battles the Mazda2 ($28,190 for the top-spec GT), Suzuki Swift ($29,490 for the Hybrid GLX), MG3 ($32,819 for the Essence Hybrid+) and VW Polo ($34,790 for the Style). Only the Polo is more expensive as its top-level variant.

Regardless of the size of the car, the Yaris ZR is missing a couple of extra things that could make it feel properly top-of-the-range. 

It’s not missing the essentials though. After an update in early 2024 it comes with a decent 8.0-inch multimedia display, wireless Apple CarPlay and Android Auto, plus an adequate six-speaker sound system.

On top of those Yaris standards, the ZR gets a 7.0-inch digital driver display, keyless entry, a head-up display, 16-inch alloy wheels, automatic air-conditioning with an air purifier and ‘premium cloth fabric’ for the sports-style seats.

It could do with a wireless phone charger and perhaps even leather seats - the latter available in the more affordable Mazda2 GT. Cloth seats and a cable to charge your phone don’t feel very ‘top-spec’. There are, however, two USB-C charging ports for doing so.

Premium paint colours (anything that’s not Glacier White) are $575, while the two-tone look with the black roof (available with Coral Rose, Bronx Bronze and Massive Grey) is $775. Our test car is Massive Grey with the two-tone black roof.

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 Toyota Yaris is a hybrid-only offering, with all variants powered by a 1.5-litre three-cylinder petrol engine that makes 67kW/120Nm and a 59kW/141Nm front motor-generator.

Toyota quotes a combined output of 85kW and doesn’t specify a total torque figure.

The electric motor draws power from a 4.3Ahr lithium-ion battery and is able to drive under electric-only power at low speeds.

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.  

Toyota claims a 3.3L/100km fuel economy figure under the combined WLTP cycle, and says it produces 76g of CO2 per kilometre.

With its 36-litre fuel tank, theoretically the Yaris should be able to travel almost 1100km on a single tank, though even Toyota admits the 3.3L/100km fuel economy figure was obtained in a lab (as is usually the case) and doesn’t reflect real-world driving.

For reference, on test the Yaris ZR didn’t display a fuel economy figure of more than 5.0L/100km during reasonable standard driving conditions.

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.

A series of factors that make the Yaris an excellent car for the inner-city also happen to make it engaging from behind the wheel.

Its small footprint and relatively low kerb weight are key to this, but it's also built on Toyota’s excellent TNGA platform which, in one form or another, underpins most of the brand's line-up.

It means the Yaris has characteristics that align with other Toyotas - it feels related to a Camry or a RAV4, even if it doesn't behave in the same way physically. 

The Yaris is understated in how it behaves on the road during regular driving, quietly switching between hybrid and electric mode, rarely letting the engine get coarse unless you put your foot down for more power.

And while the Yaris isn't quick by any means, there's just enough urgency to get you out of trouble should you need it. It's not a drivetrain that encourages spirited driving, but if you should choose to do so you'll find some surprising capability in the way the Yaris is set up.

Steering that feels light and accurate day-to-day is handy when it comes to steering the Yaris quickly on twisting roads, and the platform underneath does well to keep the light hatch and its short wheelbase in check.

It doesn't feel like it's ready to 'bounce’ off bumps and uneven road surfaces like some similarly sized hatches did even a generation or two ago, and while one wouldn't imagine the Yaris hybrid is choice number one for a weekend driver, there's still fun to be had.

But in urban environments the Yaris is in its element, and its efficient engine and small footprint make it ideal for inner-city traffic and parking.

The Yaris ZR is pretty well stocked when it comes to safety features, more so than the lower variants in the range. Great for the ZR, a bit of a let-down for the others.

It comes with all the necessary kit including auto emergency braking (AEB) with a pre-collision safety system that “recognizes motorcycles and oncoming vehicles in addition to cyclists, pedestrians and vehicles ahead”.

It also has daytime intersection collision avoidance, daytime emergency steering assist, active radar cruise control and lane trace assist, auto high beam, road sign recognition, blind spot monitor, parking support, safe exit assist and a rear parking camera with parking sensors at the front and rear.

The Yaris also has eight airbags, which is a decent count for a light hatch. There are also ISOFIX points on the rear outboard seats.

In 2020 ANCAP tested the Yaris for a five-star result, though that result expires in December 2026 and the testing criteria has since changed to become stricter.

If you’re a driver who prefers minimal technological intervention (read: beeps and bings or the steering nudging you around) the Yaris’ safety kit does a very good job of remaining in the background unless it’s really needed.

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.

Toyota offers a five-year/unlimited kilometre warranty which covers the Yaris, as well as capped-price servicing for the first five years/75,000km - whichever comes first.

Intervals are 12 months/15,000km for servicing and each costs $250.

If servicing is undertaken at Toyota dealerships, Toyota extends the engine and driveline warranty from five to seven years. It also increases the hybrid battery warranty to ten years “as long as you undertake your annual inspection as part of routine maintenance according to the vehicle logbook”.

There’s also seven years of conditional emergency assistance related to car hire or towing expenses while Toyota is maintaining the car.
