Hyundai Ioniq 9 vs Lexus RZ450E

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.

There are sportier EVs out there, there are more tech-savvy EVs out there, but few adhere to the luxury promise quite like the Lexus RZ, particularly at its price point.

It’s this primary characteristic which sets the RZ apart from the pack for me, and while it might not be for every first-time EV adopter, it nails the brief for the existing Lexus buyer while providing a ‘luxurious’ alternative to many of its firmer, sportier and less approachable rivals.

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.

I don’t think the RZ will be for everyone, but it has some very cool details and interesting angles, regardless.

It maintains the signature Lexus face, but this time has sunk the ‘spindle’ pattern deep into its plastic grille, making for a clean nose, but perhaps one which is a little too blank for some. No doubt it needs this smooth look to maintain as low a drag coefficient as possible.

Closer inspection reveals clever detailing, like the way the spindle pattern fades into the corners, and the whole look is lifted by how wide the car is. 

Sports Luxury versions are lifted further with contrast panels accentuating the width and shape.

My favourite angle of the RZ is the rear three-quarter. The coupe window line, split spoiler design, and cool strip tail-light, complete with three-dimensional Lexus branding, looks as contemporary as it gets, not to mention sportier and more intriguing than even some of its rivals.

Savvy EV buyers might know the RZ shares its platform and overall shape with the upcoming Toyota bZ4X and its Subaru Solterra spin-off, and while those two cars look near-identical from the outside, Lexus has clearly had a lot more creative licence with the design of its take on the formula.

Inside is perhaps where this car feels the most Lexus, however. The interior design is almost entirely unrecognisable when compared to the bZ4X, with Lexus going to town with its curvy, intricate design language, and plush detailing throughout.

Padded synthetic leather trims, which match the seats, adorn the doors, which are swapped out for ultrasuede in the case of the higher-grade Sports Luxury.

And Lexus has opted for a deep-set digital dash and massive touchscreen in place of the small column-mounted screen and tablet multimedia of its Toyota and Subaru relations. 

Everywhere you look, though, there’s attention to detail, with interesting material choices from the wacky carpet to the detailing on the centre console and in the door cards. It’s unmistakably Lexus, and feels premium.

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 RZ benefits from its electric-from-the-ground-up 'e-TNGA' platform, which offers an almost flat floor, wide, spacious cabin (despite its coupe-look rear) and there are plenty of clever touches throughout to enhance practicality.

The doors each offer a pocket with integrated bottle holder up front, there’s a wide centre console with a set of large bottle holders, and the clever dual-hinged armrest console which appears in other Lexus products, and a large bay under the multimedia unit which houses additional storage alongside the wireless charger.

Interestingly, the RZ doesn’t have a glove box on the passenger side, as this area is reserved for the infra-red projector in the Sports Luxury grade. 

Instead, the car has a cutaway underneath the bridge-design centre console for additional storage. It’s a welcome and surprisingly large area which also houses a 12V power outlet. However it’s a little tricky to reach when seated up front.

Adjustability feels good for the driver with decent leg and headroom, alongside a tilt and telescopic steering column.

There are dials for the climate controls and a centre dial for the volume adjustment, although there are still many functions - from drive mode to essential safety toggles - that are buried more than one menu deep in the touchscreen, and therefore a little clumsy to jab at while you’re driving.

The back seat offers excellent space for someone my size. At 182cm tall I had leagues of knee room and decent headroom, and of course all the soft trims continue. 

Bottle holders appear in the doors and drop-down centre armrest, and rear passengers score dual adjustable air vents and two USB-C power outlets. 

There are map pockets on the back of the front seats, and the higher-end Sports Luxury grade offers dual heated seats and a separate fixed sunroof panel for the enjoyment of rear passengers.

One interesting piece, however, is the high floor. Designed to facilitate the batteries, the high floor means you feel tilted back in the rear seats, like your knees are far off the ground.

The boot, meanwhile, is also surprisingly spacious given the raked rear window. At 522 litres it outranks most mid-size SUVs, and while it seems deeper than it is tall, it should be more than sufficient for the airport run or trips to the local Golf course.

An underfloor storage area is convenient for the stowage of your charging cables.

The RZ arrives in Australia in just one 450e all-wheel drive variant, with two trim levels to pick from. Either the entry-point Luxury grade ($123,000, before on-road costs), or the top-spec Sports Luxury ($135,000, before on-roads). 

It’s entering a hot market, which every luxury brand wants a slice of. Rivals include the outgoing Audi e-tron, ($138,323) which is set to be replaced by the presumably more expensive Q8 e-tron imminently, base BMW iX ($135,900), Genesis GV70 Electrified ($127,800) or the smaller GV60 ($107,700).

Soon it will also have to duke it out with the Polestar 3 which is higher performance, starting from $132,900, and there’s always the spectre of the Tesla Model Y, which is a comparative bargain at $98,415 for the go-fast Performance version.

In terms of premium-badged rivals, though, it’s at the lower end of the price-scale, following the Lexus model of providing relative value in its space.

The entry-level Luxury grade comes standard with 18-inch alloy wheels, LED headlights and tail-lights, a massive 14.0-inch multimedia touchscreen with Apple CarPlay and Android Auto connectivity, built-in sat-nav, connected services, wireless charging, a digital instrument cluster, synthetic leather interior trim, dual-zone climate control, push-start ignition with keyless entry, a 360-degree parking camera, a 10-speaker premium audio system, and the full safety suite. More on that later.

For the extra spend to get into the Sports Luxury grade, the wheels are upgraded to massive 20-inch units, then you can count on adaptive headlights, acoustic glass, contrast styling panels on the exterior (with a two-tone paint option), ‘ultrasuede’ interior trim with ‘Tsuyasumi’ ornamentation, interior LED ambient lighting, an electrochromatic sunroof, ventilated and heated front seats with infra-red ambient heating for front passengers, rear outboard heated seats, memory driver’s seat, a head-up display, touch-sensitive wheel controls, and a 13-speaker Mark Levinson audio system.

Some of these features are very cool. The sunroof and ultrasuede interior trim options with the detailed ornamentation, and even wacky carpet trim in the Sports Luxury grade, are enough to take you aback, helping this Lexus make its mark on the luxury mid-size EV market. 

Will it be enough to offset some notable omissions like the lack of vehicle-to-load systems or household power outlets on the interior?

This will depend on the buyer, but I think objectively this Lexus is playing into its existing loyal customer base more than it is the new-age tech savvy buyer.

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 RZ is only available with one powertrain choice, a dual-motor all-wheel drive set-up dubbed the 450e.

Unlike some systems, this dual-motor arrangement is far from symmetrical, with by far the majority of power sent to the front wheels.

Total system output is rated at 230kW/435Nm, consisting of 150kW/266Nm from the front, and just 80kW/169Nm from the rear.

Interestingly, this is significantly more punch than the Toyota bZ4X, further setting this Lexus apart.

The RZ uses a clever torque-vectoring system to make the most of this set-up when cornering, and debuts some interesting new tech like computer-balanced brakes to keep the car level under heavy deceleration as well as new adaptive pistons in the suspension to help the car adjust to different surfaces.

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.

Quoted range for the RZ is 470km, however this is to the more lenient NEDC testing cycle, as accepted by the Australian Design Rules. 

However, its real-world range is more like 400km, which is as it is more accurately measured to the WLTP standard.

The 71.4kWh battery pack is supported by a 150kW max DC charging speed, allowing a 10-80 per cent top-up in 30 minutes.

On a slower public AC charger, the RZ can pull a maximum speed of 11kW for charging in around six and a half hours, while single-phase charging, as you might get from a home wallbox system, at a rate of 7.0kW allows a charge time in around 10 hours.

Lexus throws in a public Type 2 charging cable, home wallbox installation, and a three-year Chargefox subscription (covering free fast charging) as part of an RZ purchase. Clever.

Officially the RZ consumes 18.7kWh/100km on the combined cycle according to the WLTP standard and I was surprised to find our car consumed 18.6kWh/100km during the test drive loop. 

For context, anything under 20kWh/100km is reasonably impressive in the premium EV space.

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.

Usually EVs, even premium ones, have a particular formula to the way they drive. 

Hefty, firm, and usually break-neck fast is the default position, with seemingly every manufacturer trying to remind buyers they too can be as fast as a Tesla.

However, the RZ breaks with the premium pack, offering a car which leans more into the luxury promise than maybe any other right now.

It’s a relatively serene space in the cabin, with notably limited wind or tyre noise, and a gentle steering tune which makes the car effortless to pivot into corners. 

This combines with the clever torque vectoring system, and lenient suspension to have the RZ simply wafting through corners.

The ride is interesting in that it is so far from the norm for the EV space. It is the opposite of firm and aggressive, with the car gently leaning into bends and barely feeling the texture of the road.

Small, rough bumps and high-frequency corrugations are dispatched with ease, the car simply floating over them, even when loaded up in corners, although, on the flip-side, longer undulations have it bouncing up and down a bit after-the-fact, perhaps a consequence of the doughy ride having to deal with the well-hidden weight of its batteries.

Despite efforts to deal with body-roll, there’s a notable amount, a consequence of the forgiving ride.

While these characteristics make the RZ a far more luxurious proposition on the road than many of its rivals, it is notable in how much it lacks a feel for the road. 

The steering is so electrically augmented it feels almost simulated, no matter which drive mode you select, and little of the road surface is communicated well to the driver. 

Even the brake pedal feels lifeless and distant, as it combines regenerative braking with the actual discs in a purely digitised progression.

The steering, acceleration and regenerative braking are all heavily altered by drive mode, with the car lacking a single-pedal drive setting, instead being fairly hands-off with the system. 

Some, looking for a particular EV drive experience, may be happy with this, others will appreciate how ‘normal’ the RZ feels in this department.

While the car feels disconnected in a sense, there’s no doubt the brakes work, the steering is effective, and it is deceptively quick. 

Its soft character might have you assuming it's slow, but a hot-hatch baiting 5.3 second 0-100km/h sprint time seems alarmingly achievable in the Sport mode.

One thing is for sure - everything described here is deliberate. Lexus has made a choice to go against the grain and do something different when it comes to the way this mid-size EV feels. 

To many existing Lexus loyalists, there will be a lot which is familiar, while providing a slice of the future, yet it might be far from the most engaging EV to drive. It certainly provides a gentler and more luxurious - if a little lifeless - alternative to the sporty status quo.

Safety comes standard on the Lexus RZ, with even the base Luxury trim-level scoring high-speed radar-based auto emergency braking (which detects vulnerable road users at night), lane keep assist (with lane departure warning), blind-spot monitoring (with rear cross-traffic alert), as well as driver attention alert, adaptive cruise control, and a tyre-pressure monitoring system as standard.

The only item reserved for the higher-grade Sports Luxury is the advanced adaptive high-beam suite.

The RZ also scores an impressive complement of 10 airbags, as well as the most recent crash structures in its fresh e-TNGA frame, however the EV mid-sizer is yet to be rated by either ANCAP or Euro NCAP.

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.

One of the key Lexus selling points is its ‘Encore’ ownership promise, which is at its best on its EV models.

For the RZ this includes a complementary 7.0kW home wallbox charger installation for those with garages, the inclusion of a wall socket and public Type 2 charging cables, a three-year Chargefox subscription keeping even your high-speed charging free for the duration.

The warranty is five years, unlimited kilometres, with roadside assist included.

Capped price servicing is available over five years, weighing in at $395 per 12 month or 15,000km interval, whichever comes first.

Lexus will also organise to pick up and drop off a loan vehicle at service time, while the high-voltage battery is covered by up to 10 years of warranty if the logbook is adhered to at an authorised Lexus workshop.

The brand also offers extra benefits through its ownership program, like deals at hotels and restaurants, as well as invites to events like track or golf days.

This is an impressive above-and-beyond suite of offerings befitting a premium brand, although it should be pointed out some premium EV rivals offer service intervals which are twice as long, and even free servicing for the entire warranty period.
