Hyundai Ioniq 9 vs Lexus LX

What's the difference?

The Hyundai Ioniq 9 is a big, comfortable and powerful SUV that ticks lots of boxes. Sadly, though, the electric power that makes it such a treat to drive is probably the same thing that will keep it off plenty of shopping lists. For now, at least.

Note: CarsGuide attended this event as a guest of the manufacturer, with accommodation and meals provided.

The Lexus LX500d is a luxury seven-seat 4WD wagon with a big price-tag to match its full-to-bursting standard features list.

The interior is now more cool than cheesy and as a daily driver and long-distance tourer the LX500d offers very impressive levels of comfort and refinement – and it’s no posh pretender off-road either.

Sure, it’s much more of a city conveyance than a country wagon, but the LX500d is spot-on for those who have a premium SUV on their mind.

I'm going to sound like a bad football coach here, but the Ioniq 9 is a tale of two halves, at least when it comes to the exterior.

And I mean that literally. The front half is lovely, with a smooth, rounded nose, two stacks of LED lights that build the horizontal on top of the vertical and a clean, modern road presence.

The back half, however, isn't. It took me a while to put my finger on it, but it suddenly dawned on me that it gives off old-school station wagon vibes that, for me at least, don't gel with the rest of the design.

Inside, though, it is a complete picture, with my only complaint that the steering wheel feels a touch too big – though I like it's more minimalist design.

Elsewhere, the materials are lovely to look at and touch – even the dash panel insert that reminds me a bit of snakeskin pants – the seats are comfortable and the tech works well.

One word on the digital wing mirrors, though. They are one cost option I wouldn't be ticking the box for. I find them off-putting, not least because they seem to zoom-in so close to the car behind that you can almost see what part of the people behind's breakfast is residing between their teeth. It feels invasive.

Plus, all you're really doing is swapping a large mirror outside the car for a big screen inside it. Conventional mirrors for the win.

The LX500d, in keeping with its positioning in the luxury slice of the market, is an imposing, premium-looking vehicle. 

Lexus puts the LX500d’s dimensions at 5100mm long (with a 2850mm wheelbase), 1990mm wide, and 1885mm high (1895mm in the Enhancement Pack-equipped LX500d). This is a big, classy SUV, inside and out, and it’s more than just a 300 Series LandCruiser in a shiny suit.

The optional 22-inch alloy wheels (part of the $5500 Enhancement Pack) add to the overall polished look. 

The interior is a classy mix of woodgrain trim, Hazel leather accents, soft-touch surfaces, Shimamoku ornamentation, plush but supportive seating, and even comfortable arm-rests.

It’s a big unit, the Ioniq 9, measuring more than five metres long, just under two metres wide and around 1.8 metres high. Weight is a hefty 2.7 tonnes at its heaviest, too, while braked towing capacity is pegged at 2.5 tonnes.

So, big numbers and a big vehicle with big storage. With all three rows in place, you get 338 litres of boot space. But treat it like a five-seater and that increases to 908 litres. Drop both rows, and you’ll have a massive 2410 litres at your disposal.

The room in the middle row is ample for full-size adults, especially if you tick the box for the cushy six-seat layout, and the rear doors feel massive, so when opened you can step through to the third row with ease, too.

Once in there, you'll find an impressively luxe space. The room isn't ridiculous, but my 175cm got in easily enough, and then fit pretty easily, too. And the addition of USB charge ports, air vents, speakers and an automatic recline function for the third row will lift the mood for whoever you put back there.

The cabin is a cavernous, plush space and driver and passengers are all generally well served in terms of practicality and comfort.

The tech is simple enough to locate and operate – it was easy enough to get Apple CarPlay working – and the screens are big: the horizontal 12.3-inch multimedia unit upfront, an 8.0-inch screen (to monitor air-con, adaptive air-suspension height, the 4WD system, and other vehicle information), a head-up display, plus a 7.0-inch touchscreen for rear passengers.

Heating and cooling are managed via the climate concierge and everyone can keep themselves as comfortably hot or cold as they like with separate controls.

Storage is only reasonable for such a voluminous interior with a variety of door pockets, cupholders (eight in total), glove box, a deep centre console (with multiple ways to open the lids) as well as map pockets for the second row, cup-holders in the centre fold-down armrest and cupholders for the third row.

The Lexus has a Qi wireless charger and front and rear USB-C charging ports – one up front, two in the second row, and two in the third row. 

There’s a 12V DC socket (front and rear) and a 220V socket in the rear cargo area.

Power-adjustable seats up front mean the driver and front passenger can dial-in their favourite seating position and these seats are very comfortable. Even the second row is plush, but the third row is not quite at that comfort level.

Second-row passengers have air con and entertainment controls, and an HDMI port.

The sunroof – an Enhancement Pack inclusion – is power-adjustable and allows plenty of natural light in through the top.

The Lexus LX500d has a claimed 174L (VDA) of cargo space when seven seats are in use; 982L when five seats are being used (that’s with each half of the power-folding third row stowed flat at the push of a button); and 1871L when all seats are stowed away (the 60:40 folding second-row seats tumble-fold forward), except for the driver and front passenger, of course. 

The tailgate has a foot-swipe-to-open sensor (part of the $5500 Enhancement Pack).

The seven-seat LX500d is the base-spec in the three-variant diesel LX line-up – below the F Sport and Sports Luxury – but you wouldn’t know it from its price-tag.

The LX500d retails for $157,061 (excluding on-road costs), but our test vehicle has an optional Enhancement Pack (which includes 22-inch alloy wheels, sunroof, hands-free power tailgate with kick sensor, $5500) and has been fitted with a towing set-up (towbar etc, $1545 fitted) pushing its price up to $164,106 (excluding on-road costs).

As standard the LX500d features list includes a 12.3-inch multimedia touchscreen (with Apple CarPlay and Android Auto, and Bluetooth), a 25-speaker Mark Levinson sound system, heated and ventilated power-adjustable seats, woodgrain steering wheel trim, 8.0-inch multi-information driver display, four-zone climate control, 7.0-inch touchscreen and separate control panel for rear passengers, multi-terrain monitor with panoramic view, and 20-inch alloy wheels (but, as mentioned, our test vehicle has the Enhancement Pack with 22-inch alloy wheels).

It has a digital rear-view mirror, adaptive variable suspension with low, normal and two high settings, as well as full-time four-wheel drive, a low-range transfer case, locking centre differential, and a variety of driving modes (including off-road modes) and driver assistants.

Exterior paint choices include the no-extra-cost Onyx, or options such as Liquid Metal, White Nova (F Sport models only), Sonic Quartz (not available on F Sport models), Titanium, Graphite Black, and Khaki Metal (on our test vehicle), all of which incur an extra cost.

There's only the one configuration available here, with Australia's Ioniq 9 a dual-motor AWD producing a combined 314kW and 700Nm – the latter ensuring this heavy EV never feels dull or sluggish.

Overseas, our powertrain is called the Ioniq 9 Performance, and it produces the fastest zero to 100km/h time of just 5.2 seconds.

The Lexus LX500d has a 3.3-litre V6 twin turbo-diesel engine, producing 227kW at 4000rpm and 700Nm between 1600-2600rpm.

It has a 10-speed automatic transmission with manual shift mode, a permanent all-wheel-drive system, low-range transfer case and a lockable centre diff. 

It also has six on-road drive modes – including Eco, Comfort, Normal, Sport S, Sport S+ and Custom – and off-road drive modes.

The V6 is an impressive fit in this behemoth, but even though this is a smooth-shifting SUV, there’s a leisurely, rather than lively, overall feel to how the engine and auto work together.

Because it is so hefty – with a listed 2690kg kerb weight – the Lexus does need a bit of heavy right boot to get going off the mark and during overtaking moves.

The Hyundai Ioniq 9 is essentially sitting atop a massive 110.3kWh battery, which produces a claimed WLTP driving range of 600km.

Be warned, though, the digital dash has a live read out of your minimum and maximum driving range, presumably judged on your driving inputs, and there is a vast gap between the two numbers. In short, if you want to maximise range, go easy on the accelerator.

Its 800V architecture unlocks 233kW DC fast charging, which the brand says will take you from 10 to 80 per cent charged in 24 minutes.

Plugging in at home, though, will be much slower than that – something like 10 hours using 10.5kW wallbox.

The Lexus LX500d seven-seater has a listed fuel consumption of 8.9L/100km on a combined cycle.

Our actual fuel consumption on this test, from pump to pump, was 12.2L/100km. Note: our test included a lot of low-range 4WDing. 

The LX500d has an 80-litre fuel tank – so, going by that on-test fuel consumption figure, you should be able to get a driving range of almost 656km from a full tank.

It's a proper surprise packet, the Ioniq 9, because you approach it with a pretty good idea of how a big, heavy and equipment-soaked seven-seat SUV is going to behave on a twisting road. Short answer? Not well.

But somehow, through some kind a wizardry, the opposite is true. Rather than feel stupendously big and heavy, the Ioniq 9 shrinks around you, feeling far smaller, more dynamic and more capable than you'd expect.

I'd maybe forgo the tightest of tight switchbacks in favour of more sweeping, undulating bends, but honestly, you can squeeze plenty of fun out of the Ioniq 9 on the right road.

Happily, it's no one-trick pony, either. It's quiet in the cabin, even at freeway speeds, it's comfortable in the city and there's plenty of space and tech on board.

The key take-away here is I like the way Ioniq 9 drives, another big vehicle helped massively by electric motors. Sometimes in big ICE-powered SUVs you can feel just how much work is going into getting them up and moving, but that's not the case here.

Instead, because there are no transmissions or turbochargers to deal with, the Ioniq delivers a rich flow of power and torque every time you push the accelerator. No lag, no whining, it just goes.

But here's the really interesting bit. It almost doesn't matter how good I say this car is, or how well I think it drives, this car will remain a niche seller. And Hyundai's executives seem to know it. And all of that's a shame, because it's really very good on the road, this Ioniq 9.

This Lexus feels tighter and better controlled than previous iterations on sealed surfaces, but it’s still a big rig so it’s no surprise when body roll continually creeps in, with this hefty SUV revealing wallowing tendencies even at optimal ride height. 

The suspension set-up – adjustable dampers, double wishbones at the front, a four-linkage rigid axle at the rear, stabiliser bars front and rear – irons out any major issues, but, even with consistent support from the adaptive variable suspension, it’s not perfect.

Steering is light and precise and adds to this posh 2690kg beast’s overall feeling of low-key composure.

This is a very nice cabin in which to spend time as NVH (noise, vibration and harshness) levels are kept to a minimum.

As mentioned earlier, the drive modes include normal, eco, sport and each adjusts throttle response, engine outputs, and gearshifts to suit the driver and the driving conditions.

Now for a few on-road niggles…

The brake pedals feel too spongy in their action – from stomp to stop – but the ventilated disc brakes front and rear do manage to wrench the Lexus to a controlled halt when needed.

The V6 and auto work well together, and though that transmission remains a smooth shifter, 10 gear ratios still seem like too many to me but, alas, that’s the way of the world.

To the off-road portion of this test…

The LX500d is a great open-road tourer but it does reveal some flaws when it comes to 4WDing – but more about those later.

As well as its robust mechanicals, the Lexus has off-road-capable Cruiser underpinnings with dirt-biased tech thrown into the mix as well. 

There’s plenty of glass around so driver-to-track visibility is fine, steering feels light but takes on a clinical precision during low-speed, low-range 4WDing.

And ‘clinical’ is exactly how the Lexus continues to feel off-road – with multi-terrain select driving modes offering auto, dirt, sand, mud, deep snow, and rock options; with a multi-terrain monitor and panoramic view helping you ‘see’ everywhere on the track; with active height control helping you to lift the vehicle’s body in order to improve off-road angles at the push of a button; and don’t forget about downhill assist control, hill-start assist, crawl control, and off-road traction control.

The danger is that – with so much tech working away at making everything so easy and safe – the driver feels completely removed from the off-road experience. The LX500d isn’t the only culprit, not by a long shot; most of the current crop of off-road vehicles are increasingly offering a sanitised, hyper-controlled version of 4WDing rather than the visceral experience many of us know and love. I’m old and grumpy, sue me.

Our test vehicle has all-season Dunlop Grandtrek 265/50R22 112V tyres, which are fine for sealed surfaces, but they’re not at all suited to the demands of low-range 4WDing in tough conditions, even more so on these 22-inch rims.

Unbraked towing capacity is 750kg, braked towing capacity is 3500kg. The LX500d has a gross vehicle mass (GVM) of 3280kg and a gross combination mass (GCM) of 6780kg.

It has a full-size spare tyre and that’s mounted under the rear cargo area.

The Lexus does not have an ANCAP safety rating as it has not been tested.

Safety features include 10 airbags (driver and front passenger: front, knee, side; rear: side), AEB with pedestrian detection and daytime cyclist detection, front and rear parking sensors, reversing camera with rear camera washer, adaptive cruise control, road sign assist, blind spot monitor with rear cross traffic alert, tyre pressure warning system, and more.

Five years with unlimited kilometres is still the underwhelming warranty norm at Hyundai. The battery is covered for eight years or 160,000km.

Happily, servicing is infrequent, with intervals pegged at two years or 30,000km. As a result, the first six years of servicing will cost a total $2005, or an average $334 per year.

The Lexus LX500d has a five-year/unlimited-kilometre warranty.

Capped-price servicing applies for three years or 60,000km, whichever occurs the soonest. 

Service intervals are scheduled for every six months or 10,000km intervals with each appointment costing $495 a pop over that period.

Lexus Encore benefits – including a loan vehicle during services, service pick-up and return, as well as valet parking offers and fuel discounts – are standard for new Lexus owners.
