Hyundai Nexo vs Mercedes-Benz EQB

What's the difference?

If nothing else the Nexo is a brilliant experiment to prove there can be more than one solution for a zero-emissions future. A lot of this depends on the power grid being more sustainable, but the most pressing issue for end-consumers, and Hyundai itself when it comes to FCEV technology, is the rollout of a more robust refuelling network.

At the end of the day, the thought of having an electric car with the range and refuelling ease of a petrol one is a much easier sell than the tall retail prices and compromises that come with an EV for every-day Australians. In a way, then, the Nexo is functionally an ideal blend of the old and the new. 

You can’t buy one yet, but as this SUV will lay the groundwork for hydrogen’s future, we’ll be watching it with a keen eye.

I really liked the combustion version of this car, the GLB, for its funky style and flexibility and I was pleased to find how easily Mercedes has made the conversion to a fully-electric layout for the EQB.

Despite a tall price, the EQB 350 is a compelling option for those seeking something a bit more luxurious than the Tesla Model Y, something a bit larger than the Volvo XC40 Recharge, and something a bit smaller than the Audi e-tron or the EQC.

The main trade-off for this 350 variant is the loss of the seven-seat layout in favour of more performance. Instead it offers a huge boot, has a sufficient range for city-based buyers, and offers surprising levels of fun, too. 

Just make sure you’ve considered its rivals which may potentially offer more range or features for the same money.

Like Toyota’s Prius, the Hyundai Nexo is not only a technology leader for the brand, but it also debuted many of its current exotic design elements long before they arrived on any mainstream model. 

A little larger than a Tucson, the Nexo has a dramatic honeycombed grille which maintains a paint finish, topped off with a strip of LED lighting which Hyundai says was to give it a distinctive look at night.

All its lighting is LED to fit with its avant-garde design, although when seen from the side or the rear it could be any mid-size SUV. 

There’s something sensible about that. The Nexo isn’t the kind of car which will polarise buyers because of its design alone.

Hidden away are very neat design elements, like functional air dams on the front guards and rear spoiler fitment, and hidden wiper blades under the bonnet cladding and tucked under the rear spoiler. 

There is also intricate pattern-work on the light fittings, making for an admirable overall attention to detail befitting such an interesting, if typically shaped, SUV.

Inside, and Hyundai points out that the Nexo was the first of its cars to get the 'bridge' centre console which now appears on the Santa Fe, Palisade, and Kona EV. 

It’s an impressive design element, really lifting the cabin ambiance on all the vehicles it appears on, although the plethora of buttons smattered across its face is reminiscent of older Porsche models, and not necessarily in a good way. It can be tough for first-time or occasional users to find the button they’re looking for.

The Nexo was also one of the first Hyundai models to score the impressive dual screen layout, consisting of a 7.0-inch digital instrument cluster, and a 12.3-inch multimedia touchscreen.

Trim options for our market consist of a two-tone cream or a navy blue leather-appointed upholstery.

Again, there are attention-to-detail elements here, with interesting grain designs across the dash-topper and door cards, with many of the fittings appearing in silver rather than black to add a touch of futuristic flair. 

Hyundai promises sustainable 'bio-based' plastics are used extensively in the interior, leading to a 12kg reduction in CO2 emissions during the production process. 

There are also vegetable oil-derived paints used in the cabin, and fibres made using corn and sugarcane waste material. Nice to have some real eco bragging rights on something a lot cheaper than a BMW i8.

The EQB has a very predictable design in that it doesn't stray from the combustion car’s formula. At all.

The only evidence from the outside this is the electric version is the blanked out grille, and closer observers might notice the rear light bar which cuts across the boot lid is different from the split tail-light design which appears on the combustion car.

Still, to my eyes, the GLB is a cool design with its upright boxy look bucking the curvaceous trend of most EVs, and, indeed, the rest of the Mercedes line-up. 

Its rebellious streak makes it one of the most appealing SUVs in Mercedes’ current range, and it comes with a bit of toughness which is missing from the EQA. 

If nothing else, it’s a completely different look from Tesla’s amorphous Model Y, and this may be enough to appeal to some.

Inside is identical to other Mercedes models which sit on the MFA2 small car platform, immediately setting itself apart with the big high-resolution screens, glitzy ambient lighting, as well as an abundance of chrome and gloss black.

It’s designed to impress from the first time you hop in, and there’s no doubt it does, but it may be a bit over-the-top for some, particularly fans of the more conservative Mercedes designs of eras past.

The chrome in particular becomes a bit of a problem, as it has an annoying habit of catching the reflection of the sun and sending it directly into the driver’s eyes.

It all feels as plush as a circa-$100,000 luxury car should though, with the ‘Artico’ seat trim being one of the better synthetic options on the market, and soft-touch surfaces throughout the cabin selling the Mercedes promise. 

The GLB toughness is even reflected in the chiselled out finishes in the door, dash, and centre console, helping to set it apart from the tamer EQA.

The software is also fast, high resolution, and well presented, which bodes well given the amount of screen real-estate, and the amount of customization is impressive, too.

Again, there are many who will prefer its look and feel to the Apple-store chic of the Tesla Model Y, or the pared back Scandinavian approach of the XC40 Recharge, but also those who won’t. Like many new Mercedes products, it continues to polarise buyers.

Being a mid-size SUV, the Nexo will possess many of the practicality attributes today’s buyers are searching for.

It has a similar right height and seat positioning to a Tucson, so it’s really bang-on for the market, and headroom despite a standard sunroof is excellent. Adjustability is also good with telescopic adjust for the wheel and 10-way electrical adjust for the seats. 

As is typical for Hyundai there are some great storage areas, with a large centre console box, a single large bottle holder and odd little storage tray, a huge cutaway underneath the console bridge (which houses the wireless charger and USB ports).

There are also large door bins, although these proved not so great for holding bottles as the door design and speakers limit the height of objects that can be placed there. 

There’s also an odd little pop-out bottle holder on the passenger side, I assume to make up for the fact that there isn’t a second one in the centre.

The back seats had a good amount of room, behind my own (182cm/6'0" tall) driving position my knees had plenty of airspace, although the presence of a 'transmission tunnel' which eats space for the middle seat was puzzling given this car is strictly front-drive only. 

Amenities for rear passengers include pockets on the backs of the front seats, a single 12V power outlet, and dual adjustable air vents. There are also small single bottle holders in the doors.

Boot space comes in at a competitive but not stellar 461-litres (VDA), or 1466L with the seats down. This is okay for the mid-size segment, although the loading lip and boot floor is quite high due to the presence of under-floor batteries. 

There is also no spare wheel for the Nexo, with only a small amount of room for a tyre repair kit.

This should be the GLB’s calling card. It’s a car with an ideal footprint, not as wide or as long as most mid-size SUVs, whilst also offering a larger cabin and boot.

The big drawback for this variant in particular is the lack of a seven-seat option, as the all-wheel drive requires the under-floor space which is required to give rear occupants legroom. 

It’s a shame, too, because I found the two rear seats in this car’s GLB combustion equivalent to be surprisingly accommodating for even adults.

As a result of these missing seats, though, the full volume can be exploited in the boot, which comes in at a whopping 495 litres.

It’s rivalled by the Model Y, which also has a cavernous boot, although it has a much larger storage area than the Volvo XC40. 

As an added bonus, there is a decent under-floor storage area which has enough space for all your charging cables, although there is no so-called ‘frunk’ with what is normally the engine bay taken up by cooling and auxiliary hardware. 

At first glance there’s so much going on under there, you’d be forgiven for thinking the EQB has an actual engine!

The cabin is also enormous as well as configurable. The EQB has massive rear doors (as it’s designed to be a seven-seater) to make it easy to get in and out of, and once you’re settled in, the amount of space for me (at 182cm) behind my own driving position is very impressive, with ample leg, arm, and headroom.

Rear passengers score the same nice synthetic leather seat and door trim as the front passengers, a bottle holder in each door, as well as two in a flip-out caddy on the drop-down armrest, two nets on the backs of the front seats, dual adjustable air vents, and power outlets on the back of the console. There is also a separate section of the split sunroof to benefit those in the back seat.

Up front the cabin is equally flexible, although it immediately seems odd that the front seats are manually adjustable. Almost unforgivable in a $100,000 car. 

At least the trim is comfortable, and again, the space is configurable for people of all shapes and sizes. 

Storage options include large bins in each door, a split-opening armrest console with USB-C outlets inside, a slide-open area underneath the climate unit, which houses a wireless phone charger and additional power outlets, as well as the usual glove box arrangement. 

Soft trims continue into the doors, although one small annoyance is the excess of chrome trim which has the unfortunate habit of reflecting harsh Australian sun into your eyes if it hits at the wrong angle.

The software is nice and quick, but can be cumbersome and over-complicated to operate at times, particularly when using the centre touchpad, or adjusting the dash with the small touch elements on the wheel. 

It is also notable the Apple CarPlay as-tested only took up a centre portion of the screen, and is not set-up for widescreen mode to take full advantage of the hardware.

Minor complaints aside, though, the EQB follows its combustion GLB twin in having by far one of the most flexible and configurable cabins in its class.

The EQB range kicks off from $87,800, before on-road costs, for the base 250, but the car we’re looking at for this review is the top-spec 350 4Matic, which wears a price-tag of $106,700.

There’s no doubt it’s a hefty price, even for an EV, and especially for a sort-of ‘small’ SUV. There’s more to consider, too. As I mentioned in the intro, the all-wheel drive system precludes the seven-seat layout in this top-spec car, and it has less range than the front-wheel drive model, too, dropping from 371km to 360km.

On the upswing, the dual-motor powertrain is far preferable to the so-so front-wheel drive option, and the 350 also gains an AMG-spiced bodykit and flat-bottomed steering wheel, as well as a panoramic sunroof.

Outside of the extra flair, the EQB 350 is almost as well equipped as you could hope, with the flashy dual-10.25-inch 'MBUX' screen set-up, Nappa leather steering wheel and interior appointments with Mercedes’ signature 'Artico' synthetic seat trim, LED headlights, ambient interior lighting with fully customisable RGB controls, dual-zone climate, a wireless phone charger, 20-inch alloy wheels, as well as keyless entry and push-start ignition.

Given the EQB’s dimensions it would seem its most direct rival is the Tesla Model Y, although it may not be a favourable comparison. 

At over $100,000 the EQB 350 is still more expensive than the top-spec Model Y Performance, which is even more powerful than our Merc here.

Other more indirect rivals include the Volvo XC40 Recharge (from $74,490 in twin-motor form), or less performance-oriented Lexus UX300e ($80,691 for the top-spec Sports Luxury), although neither are as large as the EQB, and the Lexus has about half the performance.

The Nexo’s hydrogen system is not really a drive component. It generates power for the electric motor, which is similar to the one that appears in the Kona EV. 

Like other EV models, it’s a permanent magnet synchronous motor mounted on the front axle, producing 120kW/395Nm. 

The hydrogen system is a grid of catalyst membranes which are essentially used like a giant battery to chemically combine oxygen sourced from outside the car with pressurised hydrogen. 

This reaction generates two bi-products: electricity and water, the latter of which exits the Nexo’s tailpipe.

The hydrogen system is capable of generating 135kW, just over the motor’s total output so there is always power to spare.

Powering the car’s auxiliary systems, and acting as a buffer to store excess and regenerated energy, is a hybrid-sized 1.56kWh lithium-ion battery under the boot floor.

While the EQB 350 loses its valuable third-row seats, it gains a much more impressive drivetrain than the lesser EQB 250 variant. 

While that car has a so-so front-motor set-up producing 140kW/385Nm, the top-spec 350 sports a much more capable 215kW/520Nm dual-motor system.

This allows a 0-100km/h sprint time of 6.2 seconds, and while it’s not as fast as the entry-level Tesla Model 3, it’s still impressive for a 2153kg SUV.

The all-wheel drive capability also adds a level of confidence which can’t be matched by a front-drive, more on this in the driving section of this review.

The Nexo drinks compressed hydrogen. It has 6.33kg worth of hydrogen storage tanks which grant it a generally EV-beating 666km of range. 

One of the key benefits of the hydrogen system is that it refuels in roughly the same time as it takes to fuel a diesel car, using a pressurised hose in a similar manner to an LPG vehicle.

The trouble is hydrogen is hard to source at a pump in Australia. There is one refuelling station at Hyundai’s Macquarie Park HQ in NSW, another just opened in the ACT, and a third one owned by Toyota which is about to open at its Altona, VIC HQ.

The fleet of 20 cars handed over to the ACT government will use the new pump, which for the first year will be providing free hydrogen as the system is evaluated.

Overall costs for the hydrogen after that time will depend on where it is sourced from. As Australia is uniquely positioned to generate compressed hydrogen (with an abundance of renewable energy idle time which can be stored in places like the ACT) the cost will come down over time. 

Right now, though, the brand estimates somewhere to the tune of $15 a kilo for an end-consumer, or about $90 to fill the Nexo.

Finally, a benefit for the eco-conscious, Hyundai pitches the Nexo as a product which actually leaves the air cleaner after generating energy, although there are some caveats.

The first is that the membrane requires use of platinum – a rare earth metal, and the second is hydrogen requires a lengthy, power-intensive and complex process to generate in a usable form. 

In the ACT government’s case this is less of a problem, as it will use 100 per cent renewably sourced idle energy to process the gas.

Regardless of which version of the EQB is chosen, the SUV has a 66.5kWh lithium-ion battery pack, and in the case of our all-wheel drive 350, this grants it a 360km WLTP-rated driving range between charges.

My car was reporting around 350km of range at or near a full charge, while my week of testing produced a dash-reported consumption figure of just 18.2kWh/100km.

This is surprising for two reasons. Firstly, I subjected the EQB 350 to a significant amount of freeway testing during my time with it, which usually produces worse consumption numbers for EVs, but it actually bested its official 21.0kWh/100km official figure by a decent margin.

Secondly, I’m puzzled to find this car outperformed the smaller and lighter EQA 250 I had on test in 2021 in terms of overall consumption, and by a significant margin. Very odd.

When it comes to charging up, the EQB can be charged at a rate of 100kW on a fast DC charger, for a 10-80 per cent charge time in a claimed 30 minutes. 

On the slower but cheaper-to-install AC standard, the EQB has an 11kW inverter, allowing a convenient ‘slow’ charge time of 4.1 hours. Expect between 25 and 30 hours on a standard wall socket.

To drive the Nexo is essentially no different to an electric car. It uses the same permanent magnet motor, the same regenerative braking, and the same buffer battery system.

This means a very quiet and smooth drive. It’s not quite the unleashed performance of a Tesla, but then that’s not really the point of the Nexo which leans into the comfort of the whole experience.

The drive and hydrogen reaction is entirely a silent process, although the Nexo emits a pleasant choral tone at low speed to alert passers by of its presence, same as the Kona EV.

Despite that strong torque number, the Nexo isn’t inclined to spin the wheels, and for balance reasons, Hyundai actually de-tuned the motor slightly to make it gentle off-the-line.

When it comes to corners the comfort is again emphasised, with very light and linear steering. The chassis is rigid enough to feel under control, although the comfort suspension tune will have it tilting around a little more than, say, a Tucson.

The ride is also far more forgiving than Hyundai’s sportier petrol range, with the Nexo undulating over bumps and corrugations with ease.

As is usual with Hyundai models, the safety systems aren’t too invasive, making the Nexo a friendly companion on the freeway, and the soft interior trimmings add to its near-luxurious feel.

The ACT government reps who will be receiving this car are of the mind that anybody that drives it will become an advocate for electrification, and I’m inclined to agree with them.

For most people it’s better in every way from behind the wheel when compared to a petrol car.

This is where the 350 version of the EQB shines. This car is a beast to drive with plenty of power available at your right foot, and incredible amounts of traction to match from its torque-vectored all-wheel drive system. 

This lets it be rapid, but not scary, and despite its square and upright body, might surprise you when it comes to carving a few corners.

Like many EVs, the EQB’s weight feels low and centred, but it appears the suspension has been adjusted to remove any bouncy quality, which might come with the additional weight added over the combustion variants, with nearly 500kg of lithium batteries under the floor.

In fact, the ride is also one of the things which impressed me most about the EQB. It even has huge 20-inch AMG wheels, yet it dealt with bumps of all shapes and sizes in an impressive manner, keeping the body under control, and communicating remarkably little in terms of vibration or unpleasantness into the cabin.

The steering offes a nice balance of feel and electrical assistance, a trait which combines with the EQB’s convenient size to make for an easy SUV to park and manoeuvre.

When it comes to the EQB’s traits as an electric car, there are several modes available to alter the experience. 

Using the paddle shifters, there are several regenerative braking settings to choose from. While none of them are a ‘single pedal’ mode, the D- mode is pretty strong, and clearly contributed to the EQB’s surprisingly good energy consumption in my time with the car.

Activating D+ mode, which can be combined with a sporty driving setting, tones down the regenerative setting almost completely and feels as though it unleashes more potential from the potent electric motors. 

While the sportier settings made the 2WD EQA I tested last year feel a little twitchy and prone to wheelspin, the all-wheel drive system keeps this well under control in the larger EQB for impressive acceleration characteristics.

The breadth of this SUV’s ability is perhaps its most impressive attribute. It can feel comfortable and tame around town, with alarming speed and tenacity when attacking the open road should you so desire. 

Sure, it’s not as whiplash-inducing as some of its rivals, particularly the Volvo XC40 Recharge or Tesla Model Y, but for a luxury SUV like this it’s more than what you could ask for. 

The EQB scores a thorough suite of active safety equipment including freeway-speed auto emergency braking (7.0-200km/h), lane keep assist with lane departure warning, blind-spot monitoring with rear cross-traffic alert, as well as one of the best adaptive cruise systems on the market.

In the event of an impact, the EQB scores dual front, side, and head curtain airbags (the side and curtain bags cover both rows) as well as a driver’s knee airbag. There are the usual dual outboard ISOFIX child seat mounting points on the rear row, as well as three top-tether points.

The EQB scored a maximum five-star ANCAP safety rating to the current 2022 standards, but this rating only covers the base 250 variant. It scored highly across all criteria.

Ownership is a tough one, because, well, you simply can’t own one. 

Either way Hyundai says the Nexo’s hydrogen drivetrain carries no warranty implications, meaning if you could own one (as Koreans can), it would still be covered by the brand’s five year/unlimited kilometre warranty.

In terms of servicing, the Nexo requires a visit once a year, although like a pure EV there are few items that actually need attention at one of these visits.

A top-up of coolant is only required about once every six years, and various filters need to be cycled out. Other than that, it’s just your usual wear and tear items like brakes and tyres.

As Hyundai leases the current vehicles out, it will be taking care of servicing for the initial batch.

Mercedes offers a five year and unlimited kilometre warranty, with five years of roadside assist. The high-voltage battery components are also covered by a separate and industry-standard eight-year and 160,000km warranty.

Service intervals are once every 12 months or 25,000km and the service plan costs an average of $440 a year for the life of the warranty which is expensive for an EV, especially considering Polestar offers free servicing for the first five years, and Volvo’s electric offerings are around half the cost over the same period.
