Hyundai Inster vs Toyota Mirai

What's the difference?

The target market for the Inster isn't huge, and Hyundai knows it won't be a runaway best-seller for the brand. But those in the market for a bite-sized EV will find the Inster feels bigger, and drives better, than they might expect.

Believe it or not, the Mirai represents a pretty big gamble for Toyota, a company who has been known in the past for being relative conservative with its vehicles.

In recent years though, with models like the GR Yaris and even the RAV4 Hybrid, it seems like Toyota is more willing to go out and take a chance on something that would not be considered a safe bet.

The Mirai represents this willingness to experiment, but it is still too early to say whether it will a winner or a failure.

It drives well, looks good and its powertrain is a potential gamechanger for electric cars in Australia, but whether hydrogen takes off locally with customers is beyond Toyota’s control and up to those willing to invest in refuelling infrastructure.

The words small but perfectly formed appear here, with Hyundai’s insistence on not having a traditional range-wide design identity allowing them the freedom to create something unique and pretty funky here — though I do see some shades of Suzuki Ignis in the side profile.

It does look fun though, right? With the selfie ring-light-style headlights, Tetris-style rear lights, those swollen guards and the funky alloys.

And you can dial up further with the Cross variant, which gets a tougher, more squared-off look front and back - even if you’re more chance of meeting a bunyip than an Inster on your favourite off-road track.

Inside, the cuteness continues, though some of the scratchy cabin materials definitely point to the entry-level nature of the Inster.

Still, the seat materials, both the cloth and the leather, are lovely and thoughtfully coloured, and the twin screen setup is nice, too. I love the inclusion of a host of physical buttons that control the climate, stereo and the nav.

Remember your awkward teenage years when you were still a little uneasy in your own skin and tried to find your way in terms of your own style? (I certainly do!).

Now remember bursting on the scene in your 20s with the confidence and swagger of a Calvin Klein model after working out your niche? (I’m still waiting for this to happen).

Well, the Mirai certainly remembers because the inelegance of the first-generation car has given way to a much more confident and handsome model.

From the outside, there is no denying its Toyota-ness and from certain angles the new Mirai even looks a bit like its Camry cousin, with a bit more flair.

The split front lighting signature and massive grille direct your eye to the blue-tinged Toyota badge, which the Mirai wears proudly, while the puffed-up bonnet and lower-bumper chrome accent add a touch of sportiness and class, respectively.

Move to the profile and you will see 19-inch wheels filling the arches, as well as a sloping rear roofline and silhouette that echoes the best of the premium German sedans.

From behind, the body-wide tail-light design and subtle spoiler adds to the Mirai’s strong road presence without looking over the top, but I especially like the way the lines of the former continue down the bumper to break up the body panels.

If you can’t tell already, I'm a fan of the exterior looks of the Mirai, and I bet if the Toyota badge was swapped out for a Lexus one, no one would think it looked out of place.

Step inside the Mirai and there are familiar Toyota appointments like the way the dashboard sweeps away from the driver, as well as a shifter design lifted from a Prius.

The surfaces are all soft-touch, though, and the mix of leather and gloss-black materials combine to elevate the interior ambience.

The interior of the Mirai might not be as stunning as the exterior, but it is certainly no drab and depressing place to spend some time.

The Inster stretches 3825mm long, 1610mm wide and 1575mm tall, but it rides on a 2580mm wheelbase – the later being bigger than the Hyundai Venue, and almost as big as the Kona.

It has allowed Hyundai to stretch the legroom options in the backseat, which actually gives you more space than the two bigger SUVs mentioned above, helped massively by the fact the Inster's rear pew is on rails, allowing you to slide it right back, and that it reclines a fair way, too.

I'm 175cm and I found I had more than enough leg and headroom, and with the backseat in full La-Z-Boy mode, I could sit back and relax, even on a longer journey.

It's a good thing it's four seats only, though. While the Inster feels longer than it is, it doesn't feel any wider, and even in the front seat you can feel like you're in economy class when you have a passenger on board, with both of you rubbing elbows on the central armrest.

Clever storage abounds though, with hidey-holes, handbag hooks and more dotted throughout the cabin. Opt for the roof box – and wear the efficiency penalty – and you can pop another 75kg worth of gear on the roof.

Also cool is the fact the backseats fold completely flat in the entry-level Inster, upping the storage possibilities. And in the top-spec Cross, the front seats fold down, too, allowing for fairly long items to be stowed. Though why you would need the driver's seat to fold flat is a bit of a mystery, unless you're looking to turn your Inster into an immovable storage container.

Apparently in Korea you can option a mattress that slides over all four seats, but I can't see that taking off here.

The official storage numbers are 280L and 1059L, and the small boot is helped along a little by underfloor storage where you can pop your charging stuff.

Measuring 4975mm long, 1885mm wide, 1470mm tall and with a 2920mm wheelbase, the second-generation Mirai is comparable in size to a mid-size sedan like the Camry and Mazda6.

However, it is a little longer, wider and lower, with an elongated wheelbase, and is in fact larger in all dimensions (save for height) than a Honda Odyssey people mover!

You’d think this would afford passengers heaps of room, but all the whizz-bang cutting-edge technology has to go somewhere.

Based on Toyota's new GA-L platform, the second-generation Mirai is fitted with three hydrogen tanks – two smaller ones positioned laterally behind the rear seats and one large one mounted longitudinally where a traditional transmission would sit.

What this means is that rear seat room is compromised, and the hydrogen tank eats into the middle seat’s legroom so much that the new Mirai might as well be a four-seater.

Leg- and shoulder-room in the second row are adequate, but the sloping roofline means it can be hard for taller passengers to get comfortable. I'm 184cm (6'0") and had trouble.

Move to the front seats though, and it’s a different story with comfortable and supportive seats offering plenty of adjustability for drivers/passengers of any size.

Storage options are also ample, with a door pockets, a centre storage bin, two cupholders and a tray for your phone/wallet.

Opening the boot reveals a cavity large enough for just 272 litres (VDA) of volume – less than the smaller-sized Corolla sedan (470L) and well-down on the similarly-sized Camry (524L).

Like the rear seats, boot space is compromised by powertrain components, the culprit being the battery and electric drive motor found above the rear axle.

The rear seats in the Mirai are also fixed, which means they won’t fold down to open up more volume.

With only 20 examples available in Australia, and none offered to the public to buy, it’s hard to judge exactly how much value you get with the car.

Toyota has released pricing, though, sort of.

The 20 units are available to organisations who might want to trial the hydrogen powertrain, costing $63,000 for a three-year lease.

The cost of refuelling over that period is included in the price, too, but Toyota is restricting the lease to Victorian organisations as its Altona refuelling station in Melbourne’s west.

The Mirai comes fitted with LED exterior lighting, rain-sensing wipers, auto-folding and heated exterior mirrors, 19-inch alloy wheels, rear privacy glass, synthetic leather interior, leather-wrapped multi-function steering wheel, power-adjustable front seats, dual-zone climate control, keyless entry and push-button start.

Handling multimedia duties is a 12.3-inch touchscreen system with satellite navigation, digital radio, Bluetooth connectivity, Apple CarPlay/Android Auto functionality and a 14-speaker JBL sound system.

There's no wireless smartphone charger, though, which is a big miss in our book for a car that is so future focused.

No doubt the bulk of the cost of the car is due to its cutting-edge powertrain (which we will cover further below), but the levels of equipment would be on par with high-end mid-size sedans like the $46,990 before on-road costs Camry SL Hybrid, $51,390 Mazda6 Atenza and $50,990 Hyundai Sonata N Line.

It's also hard to compare the Mirai against Hyundai's Nexo hydrogen SUV, which has no pricetag in Australia but its Korean price can be converted to around $A84,000.

The Hyundai Inster Standard Range kicks off power proceedings, with a single front-mounted electric motor producing 71kW and 147Nm.

Next is the Extended Range, which shares its outputs with the Inster Cross. Here, the front-mounted motor’s outputs have been ticked up slightly, now producing 84kW and 147Nm.

Those aren’t big numbers, but then neither does either Inster feel particularly slow or underpowered. 

What even is a hydrogen fuel-cell electric vehicle? Well, we're not scientists but the way we understand it is that there is a special component in FCEVs - the fuel cell - which combines incoming air with hydrogen to produce electricity, with the only bi-product being water.

The single electric motor driving the rear wheels of the Mirai outputs 134kW/300Nm, which enables a 0-100km/h acceleration time of 9.2 seconds in the 1900kg sedan.

Top speed is also pegged at 175km/h – or well and truly above the road-legal limit – and the electric motor is paired with a single-speed auto transmission.

Performance may seem underwhelming, especially when mainstream electric cars like the Nissan Leaf and Hyundai Kona Electric can hit triple digits in a much faster 7.9s time, but the Mirai is designed for efficiency and smoothness, not performance.

Hyundai's Nexo meanwhile, makes 120kW/395Nm from its electric motor.

Standard Range cars get a 42kWh lithium-ion battery, producing a driving range of 327km. The Extended Range and the Cross get a bigger 49kWh battery, increasing the range to 360kms. Now, that roof box. It does look cool, but you’re going to really need to carry stuff to choose that option, given it increases energy consumption by 25 per cent, reducing the Cross’s range to just 293km.

When it comes to charging, the Inster is set up for 120kW DC fast charging, or 10.5kW AC charging - provided you have that much power available at home, as most wall boxes are more like 7.1kW.

Official consumption figures for the Mirai are published at a combined 0.7kg of hydrogen per 100km… which doesn’t really mean much without a frame of reference.

The 2021 Mirai is fitted with three hydrogen for a combined capacity of 5.6kg (or 141 litres) that enables a driving range of 650km when tested on the WLTP (Worldwide harmonized Light vehicles Test Procedure) standards.

Okay so a 650km range is pretty good and comparable to diesel SUVs of a similar size, but that’s moot if refuelling costs more.

Because hydrogen refuellers are not yet readily available, the cost of refuelling is still a little unclear, but Toyota has said it works out to be around $70-80 to fully refuel the second-generation Mirai, making it comparable to filling up a petrol or diesel car.

The new-generation car also features three hydrogen tanks instead of two, which means during range is up 30 per cent compared to the first-generation Mirai.

Meanwhile, the Hyundai Nexo features a 6.33kg hydrogen tank, enough to propel it around 666km before needing a refuel.

Honestly, the impact electrification has had on vehicles in this class is staggering.

It wasn't so long ago that these micro cars were fitted with underwhelming petrol engines, four- or five-speed gearboxes and all the noise-deadening technology of a tin of beans.

As a result, they were cute, but painful. It always felt like you had to wring their neck to get the most out of them, and when you did, they were loud, buzzy and annoying.

But the Inster is none of those things. While not ludicrously powerful, the electric propulsion offered, and the nature of the way it's produced, feels ample in the little Hyundai, with the acceleration smooth, silent and easy,

It's also just generally quiet. Hyundai says it has double-sealed the doors, used thicker glass and fitted full underbody coverings to reduce the NVH - or noise, vibration, harshness - levels, and all of that, combined with the peace and quiet of an electric motor, have created a mostly blissful cabin experience.

The ride and handling hasn't been through the full Hyundai Australia ride and handling calibration of old. Instead, it's undergone the brand's more modern approach, which is to take the best componentry from what's available overseas and then build the Aussie-spec cars from there.

Either way, it all works pretty well here. Only really big bumps clang into the cabin, with the Inster otherwise riding well over all of the road surfaces we encountered.

The point, I guess, is that it's a drive experience stuffed full of happy surprises. The ride, the acceleration and the refinement are all well up on what you might expect from a city car.

Toyota is positioning hydrogen as a potential future fuel source that is – crucially – sustainable and eco-friendly, which means the Mirai has a lot riding on its shoulders.

And behind the wheel the new-generation Mirai drives just fine.

The Mirai uses hydrogen to create electricity to drive its wheels, which means it feels very much like a battery electric car from the driver’s seat.

That’s not necessarily a bad thing, but keep in mind Toyota’s potentially revolutionary drivetrain won’t feel so revolutionary behind the wheel.

Like all EVs, torque is available instantaneously for a quick and peppy pick-up off the line, but the Mirai won’t demolish the 0-100km/h sprint like the Porsche Taycan or Telsa Model S.

Designed for efficiency rather than pace, the Mirai will accelerate briskly to 60km/h, but takes 9.2s to hit 100km/h – not that we got to test the latter in the extremely short drive loop in Melbourne’s West.

Despite tipping the scales at over 1900kg, the Mirai’s ride is soft, supple and extremely compliant, almost to a fault.

Steering feels light and effortless, while 19-inch wheels do nothing to upset the serene and comfortable interior ambience – it’s seriously good enough to be a Lexus.

What’s so striking about driving the Mirai though, is how much it could appeal to motorists who travel long distances (as is often the case in Australia) and can’t afford the sometimes 10 hours required to recharge a battery electric vehicle.

Refuelling the Mirai is as quick and easy as a conventional petrol or diesel car. Australia just needs more hydrogen stations to make use of the technology and open up electrification to those that may not have considered it (or deemed it unfeasible for their needs) in the past.

The 2021 Toyota Mirai has not been crash tested in Australia or in Europe, and as such does not carry an assessment rating from ANCAP or Euro NCAP.

However, Toyota has fitted its hydrogen-powered sedan with its 'Safety Sense' suite, which includes autonomous emergency braking (AEB) with pedestrian and cyclist detection, adaptive cruise control, lane-keep assist, lane departure warning, automatic high beam and traffic sign recognition.

Other features include blind-spot monitoring, rear cross-traffic alert, seven airbags, surround-view monitor and rear-seat ISOFIX anchorage points.

The Mirai’s hydrogen tanks are also stronger than before thanks to a new multi-layer construction.

The Inster delivers super long service intervals, requiring a trip to the service centre every two years or 30,000kms, but each service is priced at $655. A Toyota Yaris Cross, for perspective, will see you visit the service centre twice as often, but each visit will only cost you $255, or $510 every two years.

The Hyundai warranty is five years/unlimited kilometres, while the high-voltage battery is covered for eight years.

Unlike new Toyotas on sale now, the Mirai does not come with a warranty because is only available on a three-year/60,000km lease.

There are servicing costs though, with Toyota charging a one-off $2693 fee for maintenance of the Mirai over that lease period.

Scheduled service periods are every 12 months/15,000km, whichever occurs first, though it is unlikely every Toyota dealership will ultimately be able to service the Mirai.
