Genesis G80 vs Hyundai Nexo

What's the difference?

Overall, then, the flagship G80 tries to be docile Clark Kent and the amazing Superman in one. As such, it stretches itself trying to be both a luxury GT and high-functioning sports sedan.

But while it doesn’t quite achieve either perfectly the Genesis gets near enough for most – especially at its exceptional price point.

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.

Australia never saw the original 'BH'-series Genesis, which was created primarily with US buyers in mind to be a 5 Series alternative at a 3 Series price, complete with rear-wheel drive and advanced chassis dynamics.

Hyundai spun the series off as a stand-alone brand in the mid-2010s within the second-gen 'DH' Genesis’ run (that did include Australia) from 2015, which is when the G80 badge arrived, while the 'RG3' redesign you see here launched in 2020.

What you’re seeing here, then, is a facelift of a half-decade-old design, and doesn’t it give off Bentley vibes? From that blocky nose with its latticed grille to the sleek profile, the five-metre long by two-metre wide G80 passes for a Continental GT wannabe. Particularly in SL guise. And a convincing one at that.

When it comes to the interior, look around. A 27-inch OLED touchscreen takes in the crisp digital instrumentation and slick multimedia displays.

We like the configurable widgets that come complete with pictures for instant recognition, and the fact that Genesis decided to put an equally-user-friendly climate-control screen below, so eyes never need to leave the road once you quickly learn where all the switchgear is.

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.

Size may not be everything, some say, but it sure says a lot when a medium-sized luxury sedan is long enough to swing it with some large Germans. And in this case, the impressive dimensions are enhanced by a three-metre-plus wheelbase.

Behind the soft-close doors, you’re met with a cabin defined by the luxury of space and isolation from the outside world – just what you’d expect from a full-sized flagship sedan. There’s room to stretch in all five seats.

Plus, in the SL, the seats and chunky steering wheel silently whirr out of the way for easier entry and egress, before sliding back to their previous-memory positions.

The front seats are among the best we’ve experienced in a long time, holding and caressing in all the right places. Switching drive modes increases bolstering and/or support, whilst longer thighs will appreciate the extendable ottoman feature. Hot/cold control and a prodding massage function further enhances the users’ pleasure.

As in all Hyundai products the digital instrumentation and media touchscreen are paragons of simplicity and clarity.

Actual knobs for audio, tuning, fan and temperature controls flank these, along with buttons for 'Home', 'Menu', 'Driving Modes', 'Cameras' and parking sensors.

So thoughtful, so easy. Even vision isn’t too bad, aided of course by the surround-views available. This is quite an unintimidating vehicle to judge when parking despite its length.

Issues? The gear selector is the circular variety Jaguar debuted with the original XF during the late 2000s and is a bit clumsy to use; sited in prime console real estate, the cupholder lid is set-up for left-hand drive, meaning it provides a (minor) obstacle for the driver when open; the test car’s carbon-fibre-look trim won’t be to everybody’s taste and there’s no walk-to/away automatic central locking.

Meanwhile, the rear seat is in the spirit of a true limo.

Wide doors allow for easy entry/egress, revealing impressive levels of space for shoulders, hips, knees and feet (though headroom might be a mite tight for taller dos due to the sunroof). The left-side rear occupant can re-position the seat in front automatically to boost legroom even more.

Airliner premium-economy class-style backrest reclination is included. And you can sink yourself or your loose digits into the tactile and aromatic bliss of the perforated Nappa leather, thick pile carpet, suede trimmed pillars and ceiling and quality textures, further upping the luxury ante.

The large folding armrest facilitates access to heating/ventilation, audio, a sunblind, cupholders, phone chargers, USB-C ports and hidden storage.

The fortunate rear-seat passengers also face air vents and a separate climate control panel from the front-seat riders. So decadent. This was clearly designed for chauffer opulence and it shows. Very difficult to fault.

But further back, it isn’t so bountiful. Literally.

The pleasingly plush boot measures in at a smallish 424 litres, and that’s almost 100L down on a 520i’s. And while it comes with a ski or 'Bunnings port', simple folding backrests would have been more practical, particularly for car reviewers who occasionally need to transport their bicycle.

Oh well, that’s what SUVs are for.

The space-saver spare, in lieu of the hated tyre repair kit, is welcome, though. Thank you.

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.

Sadly, if you’re a private buyer and not a fleet customer, you can’t actually buy a Hyundai Nexo. At least, not yet. 

The brand is currently rolling this interesting SUV out amongst special interest fleet buyers, and our test drive comes as the first 20 examples are handed over to the ACT government which is also celebrating the opening of a new refuelling station in the territory.

Hyundai is leasing Nexos out to early fleet adopters for a set (and undisclosed) monthly fee for the time being but promises it will consider taking private orders once the refuelling network is more established and its usage is better understood. 

We’ll get back to you on price if and when it becomes more available to private customers. Don’t expect it to be cheap. 

We took a look at the Nexo’s Korean retail price, where it starts from the equivalent of A$83,645 before on-road costs and in Korea’s more forward-thinking case, tax benefits.

Thankfully though, as a “technology leader” for the brand, Hyundai’s local division has chosen to import the car with every possible spec item from the factory. 

This includes a dual-screen layout with a 7.0-inch digital dash as well as a 12.3-inch multimedia touchscreen with built-in navigation, Apple CarPlay, and Android Auto connectivity, fully leather-appointed interior trim, heated and ventilated power adjustable front seats, heated steering wheel and outboard rear seats, dual-zone climate control, 19-inch alloy wheels, a sunroof, fully LED head- and tail-lights, an eight-speaker audio system, smart parking assist with remote function, flush door handles with keyless entry and push-start ignition. That’s a lot of stuff. If this were my fleet car, I’d be pretty happy.

Rivals? The only electric cars with anywhere near an equivalent range are the Tesla Model 3 ($86,325), Mercedes-Benz EQC ($141,400), and Audi E-Tron ($137,100), but as it is with these models you’re faced with high retail prices and long recharging times from anything but an ultra-fast DC station. 

There’s also the Prius-shaped-and-sized Toyota Mirai kicking around. It’s also an FCEV and also available to limited fleets.

As the alphanumerics suggest, the G80 3.5T AWD is powered by a 3.5-litre twin-turbo V6 petrol engine, producing a hefty 279kW of power at 5800rpm and 530Nm of torque between 1300-4500rpm.

Tipping the scales at 2095kg (kerb), the SL’s power-to-weight ratio is 133kW/tonne.

Drive is sent to all four wheels via an eight-speed torque-converter automatic transmission. 'Normal', 'Sport' and 'Eco' modes are fitted.

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.

Here is where the G80 has all four wheels rooted more in the past than in the future.

With no electrification of any variety (hybrid, in other words), high fuel consumption is always going to be the real price paid by going for a Euro-5 spec twin-turbo V6 weighing some 2100kg.

The official combined average figure is 11 litres per 100km, for a corresponding carbon-dioxide emissions rating of 250 grams/km. On the highway that drops to 7.9L/100km and soars to 16.3L/100km in the city cycle.

With a 73L fuel tank, that combined average number means a driver can expect around 660km of range between refills of 95 RON premium petrol, though Genesis says this G80 will also run on E10 ethanol blend.

Now, our trip computer said that we averaged less than the official figure, at just 9.7L/100km, but our pump-to-pump testing ended up being 11.4L/100km. Which isn’t that bad.

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.

The Genesis G80 3.5T AWD SL drives in a similar way to the big brutish American-inspired Caprice and HSV Grange V8s, in that it delivers effortless, lazy performance with a sophisticated twist.

No slouch off the line even in Eco mode, the twin-turbo V6 leaps into action if you’re heavy on the throttle in Comfort mode, hunkering down as the speed piles on quickly.

With 'Launch Control', the claimed 0-100km/h sprint time is 4.9 seconds, though in regular mode it is rated at 5.1s on the way to a top speed of 250km/h.

And while the enhanced exhaust orchestrates a nice warble from behind, it remains a strong, smooth and silent performer.

The AWD system is RWD-biased and is continuously variable according to prevailing conditions, performance and grip.

The SL also features an electronic limited-slip differential for better traction and grip, as well as rear-wheel steering that either counter-steers the rear wheels in relation to the front ones for a tighter turning circle (11.8m) or parallel steers them for “enhanced steering responsiveness and stability at high speed.”

Selecting 'Sport' or 'Sport+' is met with distinctly more-urgent responses, with the transmission holding on to ratios as the revs approach the red line, which can be annoying around town.

It’s quite surprising – and probably a good thing – that the beautifully balanced and connected steering can be light and easy when you’re relaxed, and yet hefty to the point of feeling heavy when you’re really on it. Likewise, the brakes in 'Comfort' are pleasantly progressive. In 'Brake Sport' they’re fiercely responsive.

Note that, in Sport+ with the safeties off, the SL's tail can become very playful indeed, even in bone-dry conditions.

Suspension is via multi-links at both ends of the car, whilst the SL grade includes what Genesis calls “Road Preview Electronic Control Suspension (ECS)”, that scans the road ahead and then adjusts the adaptive dampers for better ride comfort.

That all said, the Genesis’ sheer size and weight keep it from feeling like an out-and-out sports sedan. The speed and AWD grip is there - tyres are Michelin Pilot Sport 4S (245/40 fr - 275/35 rr) - and the handling results in some pretty astounding agility for one so large, but the steering connection, balance and alacrity are more about confidence and competence than light-footed athleticism.

This is no cut-price BMW M5. But HSV Grange owners might recognise something in its muscular good manners.

And what of the SL’s four-wheel steering? It provides a degree of tuck-in at speed which can catch out the unaware driver, though of course, it is also a boon for round-town manoeuvrability. The tight turning circle that ensues is incredible for one so long.

Ultimately, though, it is a large and heavy sedan that never quite stops feeling that way. It won’t shrink around you despite being an easy and rewarding car to drive.

Out in the wet, the AWD contributes to the G80’s squatted-down attitude, feeling impervious to prevailing external conditions.

But it’s also not quite the sumptuous luxury liner that, say, a Mercedes S450 is.

Very civilised on smooth roads, with a decent level of absorption from the multi-link suspension, the G80 struggles a little with smaller-frequency bumps at times, but then does a great job smothering the larger ones. It is certainly within the luxury sedan expectations for refinement, isolation and ride comfort, but just not the best.

If you stick with freeways and highways, this thing will bring years of civilised pleasure and punchy performance. It is a rapid yet relaxed grand touring family cruiser.

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.

Despite being so low volume, the Nexo has a maximm five-star ANCAP rating and comes with the full array of active safety items from any other high-spec Hyundai model.

Included is radar-based auto emergency braking which works up to freeway speeds with pedestrian and cyclist detection, lane keep assist with lane departure warning, blind spot monitoring with collision avoidance, rear cross traffic alert, adaptive cruise control, driver attention alert, auto high beam assist, and a top-down reversing camera. 

Also featuring is a blind-spot camera which appears in the instrument cluster when the indicator is applied.

The Nexo of course features the expected traction, stability, and brake controls, and has the regular suite of six airbags for the event of an actual collision.

The Genesis G80 comes with a five-year/unlimited kilometre warranty, five years of what it calls 'premium' roadside assistance (increased to 10 years if serviced at a Genesis dealer) and five years/75,000km of free servicing. Service intervals are every 12 months or 15,000km.

While these are about on-par with most brands, it is behind better mainstream warranty and aftersales services, which are seven, and in a few cases, 10 years in length.

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.
