Hyundai Nexo vs Lexus LM 500H

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.

The Lexus LM 500h is luxurious, comfortable, practical, easy to drive and expensive. While it may appear to be the ultimate family car, with only four seats it's limited in terms of how many kids and their friends you can carry. On top of that, the privacy screen introduces accessibility issues to the kids you wouldn't encounter on other vehicles. If you are thinking of a Lexus people mover as your next family car I'd suggest looking at the LM 350h which has seven seats and no privacy screen. If you’re looking at a business class executive van the LM 500h would be perfect. 

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 LM 500h doesn't look real. More like a concept vehicle with its vertical face wearing that enormous grille. Feels like if you watched it for long enough you’d catch it transforming into some kind of robot. Yet, at the same time its styling is elegant and prestigious.

I have a confession to make. I used this Lexus as my office. Its interior is that comfortable and spacious. I'm also a parent and there were times where it was the quietest place to get some work done.

It also let me observe people's reactions as they walked past with their dogs not knowing what was going on inside behind those tinted windows. The people that noticed were clearly car enthusiasts as they knew what they were looking at and couldn't pass without gaping it awe.

The LM 500h’s interior is superbly plush with thick carpets, beautiful copper metallic trim and nappa leather seats.

As I’ve said, the cockpit up front is less luxurious than the extravagant first class section in the back behind that dividing wall.

And yes, I’ve seen large screens before but nothing that stretches the width of the vehicle.

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.

You might be able to take Lexus out of Toyota but it's very hard to take Toyota out of Lexus and this particularly applies to the practicality of the LM 500h.

Every day I discovered new compartments, tray tables and storage areas. There are so many cabinets, lockers and hidey holes that we almost left my belongings (an entire family of plushie toy capybaras) behind because there are so many places to check.

Of course, I'm talking about the rear compartment here because up front there's not much storage. In fact, it proved to be quite a problem in that I had nowhere to put my bag with somebody sitting next to me and no area behind the front seats to stow it, either.

Talking of seats, the LM 500h only has four of them, with two up front and two in the rear. Up front, the seats are supportive and large, but the rear seats - those are, well... have a look at the images.

We’re talking two large captain's chairs that look as though they’ve been removed from the first class section of a plane.

And while this might be suitable for businesses shuttling a couple of executives to and from meetings, for a family, even with two children, the extra couple of seats a third row offers would come in handy.

The LM 350h has seven seats over three rows and no privacy screen. A far better choice for families.

For device charging there are USB ports up front and in the rear. There are wireless phone chargers for those in the back seats but not up front.

The LM 500h has a cargo capacity of 752 litres with all seats in place.

The Lexus LM 500h sits at the top of its range and is without a doubt one of the most expensive people movers on Earth with its list price of $220,888.

As you would imagine the standard features list is as extensive as it is extravagant.

For starters, while the regular LM 350h has two rows of seating in the rear (seven seats all up, including the front two), the 500h has the third row removed and just two super luxurious and enormous fully reclining seats fill the entire space. It’s like a theatre back there.

That theatre theme keeps going with a media screen in the back so large it stretches the width of the vehicle. Seriously, it's a 48-inch screen to watch movies or connect to your device.

The sound system is probably the best I’ve experienced - a spine tinglingly incredible 23-speaker Mark Levinson set-up.

What else can I tell you? Those rear seats are upholstered in beautifully soft semi-aniline leather. They’re heated and ventilated with a massaging function and... ridiculously comfortable.

There’s four-zone climate control, windows which have an electronic shade that turns the glass opaque, there are wireless phone chargers in the doors and carpet throughout so thick you sink down into it as you step inside.

Our LM 500h was upholstered in the 'Solis White' leather which also brings contrasting and mesmerising copper metallic trim.

Oh, and there’s a wall with an electric glass screen that can be raised or lowered to separate the rear passengers from the driver.

I should have mentioned this earlier. The kids loved it, but these parents spent a lot of time telling the 10- and three-year old not to put the screen up again.

The rear occupants, aka the kids, can also lock the screen in place. Which they did, and so sound proof is the dividing wall that we can only just hear their uproarious laughter.

Up front, the cockpit is comfortable but it’s clear all the space and luxury is for those being driven around.

Still, the front seats are leather with heating and ventilation, there’s a 14-inch media screen and 12.4-inch digital instrument cluster, plus a head-up display. Sat nav, Apple CarPlay and Android Auto are also standard.

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.

The LM 500h is a petrol-electric hybrid with a 2.4-litre four-cylinder turbo-petrol engine which makes 202kW/460Nm and works in concert with two electric motors.

The front motor makes 64kW/292Nm and the rear makes 76kW/169Nm. The combined maximum power output of the two motors and the petrol engine is 273kW.

The LM 500h is all wheel-drive and has a six-speed automatic transmission.

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.

Lexus says after a combination of urban and open roads the LM 500h should use 6.6L/100km. In our own testing we found consumption was higher at 9.4L/100km.

Worth noting my driving environment was mainly a hilly suburban one filled with school drop offs. Achieved some personal bests this week, with one long run to Sydney’s outskirts, only to return in nightmarish peak hour traffic.

Premium (95 RON) fuel is required and the tank size is 60 litres. In theory the driving range is a smidge more than 900km, which drops to around 640km using our real-world average.

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.

Quite simply, driving the LM 500h is like piloting a limousine on stilts. Superbly comfortable, but with an elevated driving position that offers outstanding forward and side visibility, the LM 500h is an easy vehicle to drive for long periods of time.

A digital rear vision mirror means visibility behind is good and unobstructed by the privacy screen or the seats.

The drawbacks are down to the lack of space up front, with the driver’s chair limited in its ability to recline or slide back due to the bulkhead behind it.

And that's compounded by the lack of cabin storage for bags if the front passenger seat is taken.

As for the rear passengers there aren't many people movers offering this level of comfort, except perhaps the Zeekr 009.

Variable suspension that adjusts continuously keeps the vehicle composed and provides a high level of comfort for those in the rear. At the same time, the LM stays nice and flat through roundabouts while remaining civilised over speed bumps.

And then there's the acceleration, which, while not supercar-like is incredibly brisk for a van. The all-wheel drive system provides outstanding traction in wet and slippery conditions, too. 

Our family used the LM daily for everything from school runs to shopping trips and weekends away and not only was it fun to drive, our lucky rear passengers enjoyed sitting high and being able to see clearly out their windows along with the luxury of a giant movie screen.

The Lexus  LM 500h is yet to be tested by ANCAP so it doesn't have a safety assessment score. There is, however, a high level of safety tech onboard including AEB which can detect pedestrians, cyclists, motorcyclists and other vehicles, emergency steering assist, lane keeping assistance, road sign recognition, rear cross-traffic alert, front and rear parking sensors as well as six airbags.

For child seats there are ISOFIX points and top tether anchor mounts on the two rear seats. We have a forward facing child seat and found it easy to install.

A space-saver spare wheel is located under the boot floor.

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.

Lexus covers the LM 500h with a five-year, unlimited kilometre warranty. 

The Lexus Encore Platinum program is complimentary for LM owners for three years, providing 24-hour roadside assist, a loan vehicle or pick-up/return service at service time, 'On Demand' vehicle evaluation options, valet and airport parking benefits as well as exclusive offers and event opportunities.

Servicing is recommended annually or every 15,000 kilometres, and impressively, pricing is capped at $695 per service over five years.
