Hyundai Ioniq 6 vs Lexus ES300H

What's the difference?

In the Ioniq 6 N Hyundai has built an incredibly quick and high-capable performance car. But that doesn’t mean it’s flawless and an obvious recommendation over its rivals.

Its looks remain divisive, and while obviously each individual will need to judge the design of the Ioniq 6 N themselves, objectively speaking there is a lot to like about this latest addition to Hyundai’s N stable. 

Yes, it’s very fast, but with all the N modes switched off it’s also a very quiet and relaxed sedan with a premium look and feel. So it will play the dual role of track terror and everyday family transport well. 

But it needs to be for the price, which is really testing the limits of Hyundai’s brand appeal. It obviously won’t be a best seller, but with the less-polarising Ioniq 5 N only selling approximately 300 cars since its launch, this could be a very niche proposition, reserved only for those who crave its special kind of electric performance.

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

There’s no denying the Sport Luxury is imposing, spacious, plush, chock-full of kit, efficient, speedy and pleasingly relaxing up to a point.

But its interior is also dated and true ride comfort can be elusive beyond smooth roads for this top-of-the-line version to make the grade as a proper luxury sedan.  

The ES 300h feels more like an aspirational Toyota than a Lexus for the (wealthier) masses, especially after recent triumphs like the latest NX and RX SUVs. The Camry DNA is difficult to disguise, as the amused strangers who sat in our test car uninvited thinking it was their Camry highlights.

Sure, the hybrid is no Chevy V8, but in many other ways, the Sport Luxury seems like the modern successor to the Holden Caprice experience.

The original Prophecy concept, which previewed the Ioniq 6, was a thing of beauty, a case study in elegance and simplicity. The final production version of the Ioniq 6 is a case study in awkwardness, with a design that polarised opinions.

For the Ioniq 6 N Hyundai has been given a second chance to try and make it look more appealing and less divisive. To that end they’ve added this gloss black bumper with an integrated splitter, highlighted by the N-specific fluro orange strip, as well as unique fenders and 20-inch forged alloy wheels.

The facelift also introduces much more appealing slimline headlights that help reduce the awkwardness.

At the rear, there’s a new rear bumper design, with more black to try and hide some of its most awkward lines, plus an unmissable rear wing to further attract your attention. And while it undoubtedly provides a sportier, more dynamic look, it actually provides up to 100kg of downforce.

Inside, Hyundai has made a number of key enhancements to ensure the Ioniq 6 N looks suitably sporty. There’s a sports steering wheel, complete with a pair of N buttons to immediately activate the more dynamic driving modes, plus sports seats and even a soft knee pad built into the side of the centre console, so you can brace yourself when you're lapping the track at speed.

There’s a 12.3-inch multimedia touchscreen in the centre, which houses all of the various car settings, including the very detailed N performance driving modes. This is where you can either program the N buttons or dial up the individual settings.

There’s also track-themed graphics that appear on the head-up display, if you really want to do your best Oscar Piastri impression.

Historically, cars like the ES appeal to an older and more conservative demographic, who value imposing, conspicuously-expensive looking sedans offering the luxury of space. This is the Cadillac model and our Lexus embodies it.

Which is why hire company operators snap such vehicles up. Great for airport-hotel-airport runs.

But it’s weird, given how much of Lexus’ design language is in the ES’ elaborate nose and tail treatments, how generically Toyota this looks. Certainly, our test car’s 'Sonic Quartz' white paint job does not help.

Just to reinforce this perception, two strangers were fully sat inside our unlocked test Lexus before they realised it wasn't their actual car parked nearby – a white Camry of course.

How they laughed. But if I had paid over $80K for my ES, I certainly wouldn't be amused.

The cabin is very practical too, despite its sportiness. There’s good storage spaces, including a pair of cupholders and a tray built into the centre console.

There’s also USB-C charging ports in the front and back of the cabin to keep small electric devices charged, as well as a smartphone wireless charging pad.

By relocating the controls usually found on the door (windows, mirrors, unlock/lock buttons), the door pockets have been sculpted out to create more width and space for the front seat occupants.

It’s comfortable and roomy too, especially in the back, where Hyundai has taken advantage of the Ioniq 6’s bespoke electric underpinnings to have a flat floor with good knee and legroom.

The boot measures 371 litres, which is on the smaller size for a mid-size sedan, and well short of the class leaders, like the 524L Toyota Camry.

The ES 300h may look like a gussied-up Camry on the outside, but there’s very little evidence of the Toyota inside the stretched cabin, with Lexus-specific seating, trim and dashboard.

However, if you’re familiar with the latest LS, NX or RX models, much of what you see is now dated, previous-gen tech, and that’s an issue in some key ways.

Let’s start with the SL positives, though.

Quiet and free from rattles, the interior is defined by its first-class fit and finish, and then closely followed by the vast length inside, with ample room up front to stretch out and relax in. The ES’ substantial width adds to the sense of spaciousness.

Ventilation is excellent, exemplary even, with strong and effective climate control all around the car. Great for very hot days.

The front seats provide practically infinite adjustment in most directions, and include a handy thigh-support extender that – like everything else inside – moves electrically.

Comfy and supportive, they do a fine job. Effective heated and vented cushions and backrests are further bonuses.

But let's call out the hard front headrests. They feel cheap. And the ES’ age now shows in other, eyebrow-raising ways for an $80K-plus machine.

The dash is a messy mix of now-dated Lexus styling cues – from the ugly asymmetrical centre console to the single circular instrumentation dial for speed and tachometer.

The original IS 200's analogue watch face theme was cool in '99. Today's iteration looks basic.

Storage seems poorly judged given the vastness of this sedan, provided for by cavities in the sub-sized centre armrest, glove box and door bins. Note that the latter cannot hold bottles.

Then, there’s the ill-conceived touchpad that requires brain-surgery precision when fingered to navigate the main display screen when driving (though now it's also a touchscreen, and not before time); after years of various iterations of this, it remains alien and confounding in the extreme to operate. Rest assured, it's been banished in newer-gen Lexuses.

Also annoying is the infernal ‘please obey all traffic regulations’ voice warning, just like you find in a Yaris; the limited and easily-flummoxed voice-control tech and the dated and low-fi graphics for the needlessly complicated sat-nav system.

We relied on CarPlay because the in-built item endlessly let us down. Chuck them all out.

However, there are upsides to a dated interior, because even though this is a confusing and at-times intimidating button-fest, it’s still preferable to the today's everything-behind-a-touchscreen mania.

Give us physical switches and buttons every time, like the ES. Yes, the Lexus also has them replicated within the central display, but the point is, the driver has a choice.

You shouldn't be shocked to learn that the Sports Luxury impresses most as a sumptuously comfortable back-seat experience.

Rear access is easy, the passengers can adjust the front seat, climate control and audio systems via handily-sited switches (meaning they're replicated thrice in some instances).

Limo luxury amenities include individually-reclinable and heated outboard seats that are downright sumptuous, blinds for all glass (electric for the rear window), a lined centre bin, face-level air vents, two USB ports, a 12V outlet, generously-sized elbow rests on the doors, overhead lighting and door pockets are also included.

This is tailored as an airport/hotel shuttle and very comfortable doing so.

No folding backrest, though, meaning the boot – though not small at 454 litres – lacks the load-through facilities now common in most other sedans, including the Camry.

Under the flat floor is a space-saver spare with the words ‘SPACE MISER MKIII’ emblazoned across it. Classy.

In summary, the ES’ interior is one of two parts – comfortable but dated up front, invitingly lush out back. Perfect for its intended station in life then.

The second-oldest Lexus nameplate after the LS flagship, Australia skipped the fifth-gen version from 2006 to 2012 altogether because it was ousted by the smaller, sportier and more-popular IS series.

However, the latter’s 2021 demise saw the situation flipped, with the ES retaking the mantle as the affordable Lexus sedan torchbearer, while also belatedly replacing the larger GS.

This all coincided more-or-less with a facelift later that year, which brought revised front-end styling, uprated safety, updated multimedia, extra kit and a beefier body, among other changes.

Plus, a (slightly) cheaper non-hybrid ES version returned, dubbed 250. Starting from $61,620 (all prices are before on-road costs), it uses the Camry’s 2.5-litre four-cylinder atmo petrol engine.

However, the 300h hybrid from about $2K more is the better seller, with its electric motor and battery pack assistance. Our test SL flagship kicks off from $78,180, and heaves with standard equipment.

On the safety front, the usual array of driver-assist tech is present, starting with Lexus’ pre-collision system that includes Autonomous Emergency Braking (AEB), blind-spot monitor, adaptive cruise control and lane-keep warning/assist. See the safety section for more.

The biggest change inside is the now-touchscreen-enabled 12.3-inch display, boasting a 360-degree view camera, Apple CarPlay, Android Auto, digital radio, a 17-speaker Mark Levinson audio system, CD player (!) and shockingly sub-par satellite navigation.

Beyond that, Sports Luxury buyers also score tri-beam LED headlights with adaptive high beams, an informative 8.0-inch driver display, a heated steering wheel, sunroof, powered heated/vented front seats (with memory setting for the driver), a wireless charger, head-up display, keyless entry/start, powered steering column (including retraction for easier access), active noise-control tech, rear privacy glass with sunshades, a powered boot lid with kick sensor, semi-aniline leather with a choice of walnut trims, tri-zone climate control, powered/reclining/heated outboard rear seats with centre armrest climate and audio controls, 18-inch alloys and performance (but not adaptive, crucially) dampers. More on that later.

All Lexus models also include an ‘Encore’ aftersales subscription program offering myriad offers and services including 'free' car rental.

Everything but the cliché sink, then, but is the 300h SL actually good value for money?

No rival can match the Lexus’ mix of sheer size, hybrid efficiency, spec generosity and aftersales support.

But around that $80K mark, the cheaper yet roomier Skoda Superb and smaller Volvo S60/V60 and VW Arteon 206TSI all feature all-wheel drive, as do the classy Audi A4/A5 quattros, while the rear-drive-biased BMW 3/4 Series, Genesis G70 and Alfa Romeo Giulia are far more focused on character and athleticism. Serious competition all.

And, as we found out, none can be mistaken for a Camry. Image is important at this level.

As mentioned earlier, while it may be expensive for a Hyundai, if you want a car capable of making 478kW and 770Nm you’ll typically need to spend a lot more than $115,000. This makes the dual-motor electric powertrain the star of the show in many respects.

Those figures are the maximum performance available when you use 'N Grin Boost', a 10-second burst of ultimate power. The ‘normal’ performance is a still an incredibly impressive 448kW and 740Nm.

These come from a 166kW front motor and 282kW rear motor, to give you all-wheel-drive capabilities.

That’s enough for the Ioniq 6 N to do the 0-100km/h sprint in just 3.2 seconds with N Grin Boost activated (0.2 seconds faster than the Ioniq 5 N). Top speed is limited to 257km/h, which is obviously too much for the road, but Hyundai is pitching this as a track car and in that sense it will struggle to keep up with some supercars at the end of long straights, but that’s probably a minor quibble in the grand scheme of things.

Like most electric cars, the Ioniq 6 N has a single-speed transmission. But like the Ioniq 5 N, Hyundai has developed an artificial ‘manual’ gearbox, which it calls N e-shift. By torque limiting the engine to create a false ‘rev limit’ there are eight virtual gears for you to use via the paddles on the steering wheel.

But this is only part of the story, Hyundai has included a number of N-specific driving settings for the powertrain beyond N Grin Boost and N e-shift. N Torque Distribution has 11 different settings that allows you to adjust the torque split between the front and rear axles up to 95 per cent in one way or the other.

Then there’s N Drift Optimiser, which helps you do big skids, on the safety of a track, of course. Plus N Launch Control to shock your mates with V8s at the drag strip and N Track Manager to keep track of your lap times.

It all sounds very complicated but Hyundai has done a nice job of integrating the systems into the car and making the menu easy to navigate. And because these systems are largely digital, rather than mechanical, it actually helps make the car easier to drive in some regards.

Doing duty in a cornucopia of Toyota products, the ES 300h’s A25A-FXS engine remains the same as the pre-facelift model, meaning it is a 2487cc (2.5-litre), double overhead cam, 16-valve Atkinson Cycle in-line four-cylinder petrol unit with variable valve timing.

In this application, it makes 131kW of power at 5700rpm and 221Nm of torque between 3600rpm and 5200rpm, and sends that through to the front wheels via an e-Continuously Variable Transmission (CVT) with a sequential shift facility offering artificially stepped 'ratios' for a more-conventional automatic transmission sensation.

A series/parallel full hybrid system, the engine is backed up by a permanent magnet synchronous electric motor, delivering 88kW and 202Nm, and is fed by a tiny 1.6kWh Nickel-metal hydride battery pack.

With only a couple of kilometres of pure-EV driving availability, and only under light throttle or when coasting along, the latter is recharged via the petrol engine as well as recaptured energy from the regenerative braking system. Combined power output is 160kW. No combined torque maximum is stated.

With an impressive power-to-weight ratio of 92kW/tonne, the 1740kg 300h needs 8.9 seconds to reach 100km/h, and maxes out at 180km/h.

To handle all that movement and mass, the steering is an electrically powered rack and pinion set-up, the front suspension consists of MacPherson-style struts and the rear suspension is made up of a multi-link arrangement.

To power this track-focused EV, Hyundai has had to upgrade the 84kWh battery with specialised heating and cooling systems.

Range is rated to 487km, which is good without being great. And, unsurprisingly, if you access all the power available you will end up using the battery quicker, much like you’ll use more fuel if you drive an internal combustion engine hard.

For track use, Hyundai suggests a ‘20-20-20’ cycle of 20 minutes of track driving, 20 minutes of cooling and then 20 minutes of charging to ensure you get maximum out of a track day. Although we were able to do closer to 30 minutes of track driving from a single charge.

To make this possible, there is a special N Battery mode, which is able to maximise track usage by managing the cooling and output depending on the scenario. There are Drag, Sprint and Endurance settings, with Drag making the battery warmer for sudden acceleration, Endurance trying to keep it cooler to extend on-track range and Sprint automatically applying N Grin Shift when needed.

It’s an incredibly complex system but it speaks to the challenges of making an EV capable of the rigours of high-speed driving consistently.

In terms of charging, the key detail to know is, with the maximum charger, you can go from 10 to 80 per cent charge in as little as 18 minutes, according to Hyundai’s claim, and is compatible with either 400V or 800V charging infrastructure.

Rated as Euro 6, the ES 300h requires a minimum brew of 95 RON premium unleaded petrol.

But that’s where the bad news stops, because over 626km of all sorts of driving in hot weather with the tri-zone climate control in full workout mode, we averaged an extremely commendable 5.6 litres per 100km. Well done, Lexus.

That’s against the official combined average of 4.8L/100km, which equates to just 109 grams per kilometre of carbon dioxide emissions. Not bad.

With the 50L tank brimmed, expect a real-world range of about 890km – or 1041km using the official average fuel consumption figure.

Either way, the 300h is mighty frugal for a 5.0-metre long and 1.8-tonne luxury machine. But cab and hire companies already knew that from their Camry hybrids, right?

To put it bluntly, the Ioniq 6 N is sickeningly fast. Literally, it can make you feel car sick from the passenger seat if the driver unleashes the power a little too frequently, which isn’t hard because the Ioniq 6 N offers near-instant torque.

The dual motors mean this swooping sedan launches out of corners with a ferocity usually reserved for supercars - it is that quick under hard acceleration. But pure acceleration is only part of the story when it comes to a proper performance car.

As impressive as the Ioniq 5 N is, it was always going to be handicapped by its taller SUV body, meaning the handling was somewhat dulled by its size and shape. The lower, more aerodynamic Ioniq 6 N is therefore noticeably more dynamic and responsive to drive.

The suspension and steering tune isn’t specifically tuned for Australian conditions, instead it’s based on the globally developed setup designed for the Ioniq 5 N, which Hyundai Australia did have input into.

Despite not being tuned specifically for Australia it still rides with impressive compliance for such a performance-orientated electric car. Even on the choppier back roads we tested it on, it feels controlled and compliant while still being responsive, without feeling uncompromising or uncomfortable.

But to really experience the true performance potential of the Ioniq 6 N, you need to hit the racetrack. Thankfully, Hyundai Australia allowed us to test it to its limits at Sydney Motorsport Park.

Free from speed limits the immense power can be unleashed and to make the experience even better you can use the N e-shift and the N Active Sound+ - three separate artificial soundtracks that are designed to mimic engine noise.

There is one that can broadly be described as ‘futuristic’ and another that is meant to sound ‘electric’ but neither are good enough to bother with. Instead, if you stick to the one that sounds like Hyundai’s petrol engine you’ll enjoy it.

While it is clearly an artificial sound, and there will be haters who just don’t like it (and they can leave it switched off), Hyundai has done a brilliant job mimicking the sounds of a proper petrol performance car. So much so that when you lift off the accelerator, you actually hear a ‘snap, crackle, pop’ from the rear of the car, as if there is an actual exhaust making the sound.

What the noise does do is really help you with a sense of speed, as does the N e-shift, not only helping you drive faster but also just making the experience more fun.

For the serious track-day drivers the amount of adjustability in the Ioniq 6 N is brilliant. In particular the N Torque Distribution system, which allows you to shift the drive split front-to-rear on the move. Experimenting with this system, there is a clear difference between the handling not only as you switch between modes, but if you’re really, really serious, you can even adjust it during your on-track run. As the tyres get hotter, shifting more drive rearwards helps the car rotate better and punch out of the corners easier.

However, while Hyundai may have designed it as a track-capable, ‘Corner Rascal’, as they like to say, the reality is, most of the time you’ll be driving, you won’t be on a racetrack.

Even so, N Road Sense is a special setting that is able to recognise a double curve road sign and urges the driver to activate N mode and have more fun, so it’s always looking to encourage you to have a good time.

But what about when you’re not driving fast? How does the Ioniq 6 N stack up as a daily drive? Well, one of the elements of  performance EVs that I personally appreciate, is how quiet and relaxed they are when you don’t need to go fast. Unlike an internal combustion performance engine, which can feel like a caged animal at suburban speeds, an EV with 448kW is as smooth and quiet as an EV with 148kW.

It means it plays both its roles - weekday commuter transport and weekend fun machine - with equal ability.

In the right conditions, the ES 300h is a big, squishy, comfy drive. At low speeds, for instance, thanks to an airtight cabin that does a great job isolating its pampered occupants from the outside world.

You cannot hear the car on start-up because the electric motor whirrs this Lexus off the line instantly, silently and effortlessly. And aided by all the surround-view cameras, the steering is light and direct enough to make parking a breeze. Automotive Valium to soothe your weary head after a long day.

Likewise, get the ES out on a smooth motorway and that relaxed feeling remains, with the 300h being right at home as it lopes along quietly and steadily. Cocooned in sumptuous leather and walnut, the adaptive cruise control gently rolling with the ebb and flow of traffic, it’s easy to zone out in here.

Find an empty stretch of road and you might also be impressed at how instantaneous the 300h’s throttle response is, leaping into action and piling on the speed without even breaking a sweat. This thing ain't slow!

Likewise, if you must hurry through a tight set of corners, the Lexus will remain composed and in control, without skipping a beat. Even the brakes seem well tuned and nicely modulated – something that many electrified vehicles struggle to achieve. It’s all so nice and easy.

So, what’s the catch?

First of all, while hushed when pussyfooting around, the illusion of posh sophistication is shattered once the accelerator pedal is prodded down hard, with the accompanying engine noise seeming incongruous.

Perhaps it’s because we’ve been lulled into an electric peace, but once the revs are up, no amount of sound-deadening will quell the mechanical roar.

And it's that same Camry hybrid symphony you've probably heard hundreds of times before, in the back of a taxi hurrying to the airport.

Except in the Lexus, it's far-more muffled. Like you're wearing headphones. 

Then there’s the question of bonding. While the ES 300h will do what’s asked of it capably and without complaint, there is nothing to connect car with driver.

By this, we mean that the steering is remote and feels numb at all times, with little to no feedback. Enthusiasts will search for the short way home. This is the anti-Alfa Giulia - technically a rival.

Most people will not care about that, but on the Sport Luxury’s 18-inch wheel and 235/45R18 tyre package – while modest by today’s standards – the ride quality is less than ideal on anything but smooth roads.

The ES can easily cope with small-frequency surface irritations, but seems to lack sufficient suppleness dealing with larger bumps and pot holes.

There’s an underlying and often unyielding firmness that undermines this car’s luxury aspirations. We’d dial back the taut handling for more cushiness if we could. Or fit a decent set of adaptive dampers.

Plus, the Dunlop Sport Maxx tyres aren’t as quiet as we’d expect on some of our coarser bitumen surfaces.

Comfy on smooth roads, fast when you need it to be, fit enough to go exactly where you point it to without losing composure, and wonderfully economical even when driven like it’s been stolen, the 300h has much to offer from a driving point of view.

But you won’t be aching to drive it just for fun’s sake. And you’ll quickly learn which roads are less than perfect in your neck of the woods.

Tested in 2018 under a less-strict regime, the ES delivers a maximum five-star ANCAP crash-test rating result. Back then, it scored especially strongly in Adult, Child and Vulnerable Road User categories, and quite well for Safety Assist tech.

There are 10 airbags in total (offering dual frontal, side chest, side head and front-occupant knee protection). The AEB system works between 10km/h and 180km/h, while the lane-tracing, lane-keep and emergency steering assist systems are operational from 50km/h to 200km/h.

Other driver-assist tech includes rear cross-traffic alert, blind-spot monitoring, adaptive cruise control with full stop/go and road-sign recognition and 'Intersection Assist' with 'Turning Assist'. The latter warns and brakes the car if the driver attempts to turn into oncoming traffic.

These are backed up by adaptive LED headlights with auto high beams, 360-degree view cameras, tyre pressure monitors and 'Lexus Connected Services' that can notify emergency services in an accident and track a stolen ES. An alarm with intrusion sensor is also fitted.

You’ll also find anti-lock brakes with brake-assist and electronic brake-force distribution, stability and traction control systems, three rear-seat child-seat tether anchorages and two ISOFIX latches, fitted to the outboard positions of the back bench.

Hyundai covers the Ioniq 6 N with its usual seven year/unlimited kilometre warranty, with any non-competitive racetrack usage also covered. So you can do a track day, including the official N Australia organised ones, with peace of mind.

This applies even if you upgrade your tyres and brake pads in search of faster lap times, as long as you don’t enter into a competition, Hyundai will look after most mechanical on-track problems.

Service intervals are every two years or 30,000km, whichever comes first. Hyundai offers a ‘lifetime’ servicing plan that covers the first four years, but with only two services required - one for $645 and the second for $667.

As one of the best-selling brands in the country, Hyundai has an expansive nationwide dealership network, including extensive rural coverage and service centres trained to deal with EVs.

Here is where Lexus really excels nowadays.

Since the beginning of 2021, it caught up with most other manufacturers by offering a five-year, unlimited kilometre warranty with roadside assistance – up from four-years and 100,000km previously. Free towing and loan vehicles are provided for that period, too.

Service intervals are at 12 months or 15,000km, whichever comes first.

The ES offers three years and 45,000km of capped-price servicing, with each one costing $495 – as well as a free loan vehicle and car wash.

Plus, there’s also Lexus’ ‘Encore’ aftersales subscription program offering myriad offers and services.
