Hyundai Ioniq 5 vs Lexus GX 550

What's the difference?

The Hyundai Ioniq 5 Epiq N-Line AWD leverages an electric powertrain’s best attributes brilliantly well.

It’s ultra smooth and comfortable with ample performance and great dynamics thanks in part to this car’s N Line spec.

Its price tag pits it against formidable competition from the German Big Three, Tesla and others. But it has what it takes in terms of quality and value to fight that battle. It’s an impressive machine.

The retro-cool Lexus GX550 Overtrail is a solid mix of understated style, on-road performance and 4WD capability.

It’s suitably refined, luxurious and it’s a comfortable off-roader – and if you’re planning to cross-shop it against the likes of Land Rover Discovery, Toyota LandCruiser 300 or Land Rover Defender it actually compares quite favourably.

But there are some negatives: the Overtrail’s fuel consumption impacts its general appeal as a day-to-day driver, it lacks people-carrying flexibility without that third row of seats and the fact there’s no diesel Overtrail on offer is a real letdown.

Still, there’s no denying this is a worthy contender among the current line-up of large luxury SUVs and it makes a lot of sense.

Is this a big hatchback or a mid-size SUV? I’m on team hatchback, while Hyundai defines the Ioniq 5 as an SUV.

But who cares? They’re just words and the fact is even after close to three years in market this five-seater looks fresh and contemporary thanks to its confident, chiselled lines and wide stance.  

For car-spotters the N Line exterior treatment consists of flat aluminium badging, specific bumpers front and rear, with a deeper nose spoiler incorporating larger vents to cool the front brakes.

There’s also body-coloured cladding and side skirts, gloss black mirror caps, unique 20-inch alloy rims and a ‘hidden’ lighting signature across the top of the front bumper.

Inside there are Alcantara- and leather-appointed seats, an N Line-exclusive partially-perforated leather steering wheel, red contrast stitching and accents, and brushed metal covers on the pedals.

Add in the twin 12.3-inch screens display and this understated, super-cool interior comes to life with a sporty twist. 

The Ioniq 5 scores points for a manual dial for audio control and an Ioniq 5 update earlier this year included a row of simple-to-use buttons for the ventilation system and another on the centre console for seat comfort settings and more. A sensible blend of physical and digital controls.

The Lexus GX550 Overtrail is 5015mm long (with a 2850mm wheelbase), 2000mm wide, 1935mm high, and it has a kerb weight of 2515kg.

It has a chunky, almost straight up and down, old-school look, and leans heavily into retro cool rather than sleek styling.

A big front grille, bulging wing mirrors (more about those soon), as well as Toyo Open Country all-terrain tyres, wheel arch mouldings, and side steps that are all on the correct side of large, add to this wagon’s overall presence.

The bulky wing mirrors offer only a narrow field of rear vision, which is peculiar given the mirrors’ size and that field of rear vision is also vertically oriented which is even more peculiar.

The Overtrail has black trim highlights, and bridge-type roof rails that top off its sporty look.

Inside, there’s a little more posh-ness going on: most striking of all is the olive green synthetic suede accents and stitching added to the front seats, while the rest of the interior mostly consists of soft-touch surfaces with a smattering of durable plastic.

The interior is low-key classy with great build quality.

At just over 4.6m long, a little under 1.9m wide and a fraction more than 1.6m tall the Ioniq 5 comfortably fits the medium SUV profile.

But arguably its most significant dimension is a 3.0m wheelbase which is huge for a car of this size as evidenced by the wheels pushed out to the corners.

What that means is plenty of space inside, but before you can even get in the capacitive touch power door handles may look cool and help aero performance with their flush fit design but I’m not a fan. They’re hard to grip most of the time and don’t work well from an ergonomic point-of-view.

That said, once inside the front seats are adjustable six ways to Sunday and at 183cm tall I have plenty of head space and breathing room in general.

In terms of storage there are big pockets in the doors with room for bottles and thanks to the ‘shift-by-wire’ gear controller located on the steering column there’s room between the seats for a substantial console including a pair of cupholders, a slot for devices and a lidded tray (which doubles as a centre armrest) with that whole rear section able to swing up to allow access to a large lower shelf underneath.

In fact, the entire console unit easily slides fore and aft to liberate more legroom for the centre rear position. There’s also an oddments cubby in the lower part of the dash and a decent glove box.

Then, for connectivity and power there are three USB-C sockets (one in the dash switchable to streaming), a wireless device charging pad and a 12-volt outlet.

In the back that long wheelbase comes into its own. Sitting behind the driver’s seat set for my position I have loads of foot, leg and headroom.

Storage runs to door pockets with room for bottles, a fold-down centre armrest with a pair of cupholders, there are netted map pockets on the front seat backs and pull-up sun shades on the rear windows.

There are controls for the front passenger seat on the inner edge of the front passenger seat backrest which allows rear seaters to adjust its position. Thoughtful.

For power there’s a pair of USB-C sockets and individual ventilation controls in the back of the B-pillars is welcome. 

Then, not only is the electrically-adjustable rear seat split 60/40 in the backrest, it’s in the cushion, as well, which adds extra flexibility in terms of a balance between rear passenger space and room in the boot.

The boot is generous at 527 litres (VDA) with the rear seat upright and 1587L when it’s folded down.

There’s also a handy 24L ‘frunk’ under the bonnet, a decent portion of which is devoted to the (included) charging cable.

Interestingly, the Ioniq 5 AWD is rated to tow a 1600kg braked trailer with a trailer pre-wiring package standard. 

There’s a repair/inflator rather than a spare tyre, which is never a good thing, but there is a ‘smart’ power tailgate and a ‘Vehicle-to-Load’ function that allows you to power and/or charge three-pin appliances from the car. Handy.

This is a Lexus so, of course, the Overtrail’s practicality comes with lashings of prestige.

As mentioned, build quality is impressive, as is overall fit and finish. The olive green synthetic suede front seat accents and stitching are nice subtle touches – it adds nothing in terms of practicality but geez it looks good.

The 14.0-inch multimedia touchscreen system dominates upfront. While setting up wireless Apple CarPlay was easy enough, I had consistent issues with it and needed to repeatedly stab my finger onto the screen in order to work my way through countless menus and sub-menus to actually eventually reach the function I wanted to reach – and that’s far from ideal.

I’ve experienced this in several new-gen vehicles and my tip to you is: while the vehicle is stationary, work out how to use the functions you need/want to use most often, because the operation of some of those functions is counter-intuitive.

The driver also gets a 12.3-inch digital cluster with a variety of vehicular information to keep track of and a head-up display, which is a handy addition but polarised sunnies rob you of that.

There’s also a powered sunroof.

Otherwise, there are plenty of charge points, including a wireless phone charging pad in front of the cooled centre console, six USB-C ports, and 12-volt outlets front and rear, and a 220V outlet in the rear cargo area.

There are also cupholders galore – upfront and in the second-row armrest – and too-small bottle holders in the doors.

And – whoo-whee! – are the seats in here so bloody comfortable! Obviously upfront, ventilated, heated and power-adjustable etc are the pick of the pews, but the second row is no Gulag jail cell either. There’s room enough there for three burly blokes - just.

The Overtrail does not have the third row of seats as the Luxury and Sports Luxury do, but that frees up more space in the rear cargo area. Cargo space is listed as 1063L with all seats in use, and 2000 litres if the back row is folded down.

The rear cargo area has a 220V/100W socket (to run camp lights, fridge etc), a cargo blind, tie-down points and leftovers from the seven-seat layout: cupholders on both sides.

The rear tailgate is powered and lifts to open rather than swings to the side like the previous barndoor-style tailgate. Bonus: you don’t have to open the whole door to gain access to whatever gear you’ve stowed away in the rear cargo area; you can open the glass section only and reach in through there and that’s a very handy feature.

The Overtrail’s full-size spare is mounted to its underbody.

The 2024 Lexus GX550 is available in three grades: the seven-seat Luxury ($116,000, all excluding on-road costs), the five-seat Overtrail from $122,250 and the seven-seat Sports Luxury at $128,200. 

Our test vehicle is the Overtrail and its price as tested is $126,450 (excluding on-road costs) because its additional features are 'Moon Desert' two-tone paint and grey windshield sub-moulding ($4200).

Standard features on the Overtrail include an 14-inch multimedia touchscreen system (with wireless Apple CarPlay and Android Auto), a 12.3-inch digital cluster, heated and ventilated leather-accented, eight-way power-adjustable front seats, a 360-degree camera system, three-zone climate control, a refrigerated cool box/centre console, a power tailgate with fold-out glass hatch and more.

It also gets 'Adaptive Variable Suspension', electronic 'Kinetic Dynamic Suspension System' (eKDSS, essentially an electronic active swaybar), 'Multi-Terrain Select' (a Toyota off-road traction control system), 'Multi-Terrain Monitor', crawl control and a locking rear differential.

Exterior paint choices include 'Sonic Quartz' or 'Graphite Black' – or you can opt for a two-tone colour – such as 'Titanium', 'Titanium Carbide', 'Moon Desert', or 'Khaki Metal' – but those colours will each set you back $4200.

The Ioniq 5 Epiq AWD is powered by a permanent magnet synchronous electric motor on each axle, both powerful, but the rear unit packs a bigger punch.

And combined peak outputs of 239kW and 605Nm are substantial with especially the latter delivering eye-widening acceleration.

Drive goes to all four wheels via a single-speed, reduction gear auto transmission on both axles. And a ‘Disconnector Actuator System’ is able to disengage the front wheels to reduce drag losses from the front motor and improve energy efficiency.

The GX550 Overtrail has a 3.5-litre twin-turbo V6 petrol engine – producing 260kW at 4800-5200rpm and 650Nm at 2000-3600 rpm – and that’s matched to a 10-speed automatic transmission.

This is an impressive combination: smooth, plenty of torque across a wide rev range – punchy off the mark, and refined at highway speeds, always controlled, always comfortable.

The Lexus GX550 Overtrail has full-time 4WD and an electronic rear diff lock.

Its selectable driving modes include Normal, Eco, Comfort, Sport, Sport S and the Overtrail also has 'Adaptive Variable Suspension' and 'Multi-Terrain Select' with drive modes, such as Dirt, Sand, Mud and Snow, designed for off-roading.

The Ioniq 5 Epiq AWD is powered by an 84kWh liquid-cooled lithium-ion battery, borrowed from the high-performance Ioniq 5 N.

Thanks to 800-volt compatibility it can accept a 350kW DC charge which translates to an up to 80 per cent charge time of around 18 minutes, which expands to just over an hour using a more typical 50kW charger.

Connect to AC at the Ioniq 5’s maximum 10.5kW capacity and quoted charge time is just over six hours.

Official energy consumption on the combined (urban/extra-urban) cycle is 19kWh/100km and claimed range is a useful 495km.

Over a mix of urban, suburban and freeway running on test we saw a real-world average of 16.8kWh/100km, which is impressive for a car with this much performance potential.

Fuel consumption is listed as 12.3L/100km and that's on a combined cycle.

On this test I recorded 13.9L/100km but, as I have a penchant for dirty stuff, I was doing a lot of low- and high-range 4WDing so I think that figure is actually pretty decent for a 2.5 tonne vehicle with a V6 petrol engine. That’s okay, but I can see those fuel figures climbing considerably once you load the Overtrail up or you tow something with it: a boat, a camper trailer, or a caravan.

The Overtrail has an 80-litre fuel tank so, going by our on-test fuel figure, you could reasonably expect a driving range of about 575km from a full tank.

In terms of straight line performance we’re talking 0-100km/h in a tick over 5.0 seconds and I see anything in the five-second bracket as properly quick.

With more than 600Nm of peak pulling power at your disposal there’s always plenty of pulling power for efficient in-traffic moves and safe highway overtaking.

The shift-by-wire gear selector on the steering column takes some getting used to but once you’re in tune with it, it’s surprisingly convenient, especially during slow speed parking or turning manoeuvres. 

There are multiple modes - ‘Eco’, ‘Normal’, ‘Sport’ and ‘Snow’. Sport mode spices things up a bit with more urgent responses and the ‘HTrac’ AWD system uses multiple sensors to manage potential wheelspin and optimise drive in wet conditions or on loose dirt surfaces.

Suspension is by struts at the front and multi-links and the rear and the Ioniq 5 in this configuration is ultra-smooth and comfortable.

Even hitting pretty aggressive speed bumps and ruts in the road and the car soaks them up without fuss. You’re used to EVs being a little harsh in terms of ride compliance thanks to their relative weight, but that’s not the case here.

As part of a model upgrade introduced earlier this year Hyundai says it undertook a “comprehensive revision to the suspension tune”, which includes high-performance dampers on this N Line. And despite low-ish profile (255/45) Michelin Pilot Sport EV tyres on the 20-inch rims it remains comfortable and quiet.

The upgrade also included body reinforcements in the B- and C-pillar, door surrounds and under the body for a stiffer platform overall.

That pays off in the dynamics. Despite its 2.1-tonne weight the Ioniq 5’s steering is accurate and nicely weighted. It doesn’t feel lumbering or ponderous despite its relative heft.

The physical brakes are ventilated discs front and rear with regenerative available through four levels, the most aggressive setting being ‘i-Pedal’ which allows single-pedal driving.

It will slow the car to a full stop, harvesting the most energy possible in the process, although you might need a dab on the brake pedal if things are tight.

Miscellaneous observations include a 12m turning circle, so be ready for three-point turns where you didn’t think you’d have to.

Hyundai's (and Kia’s) default over-speed warning is present in full-force taking clicks through multiple screens to switch off and avoid its incessant audible alarm saying you've exceed what the car believes is the posted limit (every time you restart the car).

The recently released Tucson Hybrid features a short-cut function to do away with this issue and it would be welcome here.

The CPU underpinning the multimedia system is more powerful and response is speedy without a hint of lag.

And the camera based ‘mirrors’ take some getting used to. For many, they’re the answer to a question no one was asking. I mean, conventional mirrors work pretty well and any aero benefit from the smaller camera units has to be modest. But once you’re in tune with them the hi-def screens are excellent.

A flip of the switch on the interior rear view mirror allows you to side-step tall heads or loads in the back of the car but minimal depth of field is also (visually) awkward at first.

The smooth Overtrail driving experience begins before you even push the start button: the Overtrail has big grab handles for each door – and I bloody love a good solid grab handle.

Also, the combination of power-adjustable steering wheel and driver’s seat means you’re able to precisely dial-in your preferred driving position.

On road and at speed on dirt tracks, the Overtrail sits nicely. It has a wide wheel track and long wheelbase, so it retains a controlled and composed posture on sealed and unsealed surfaces. 

Some body-roll does creep in when you throw the Overtrail into a corner hard, but that won’t surprise you if you’ve spent any time at all in a large or upper large 4WD wagon recently and that characteristic is no deal-breaker.

Ride quality is very impressive and the suspension set-up – double wishbone IFS with eKDSS at the front, and four-link live axle with eKDSS at the rear – mostly soaks up any bumps, however, it does skip over some more substantial irregularities in the road/track surface here and there, but that’s mostly ironed out by the Overtrail’s adaptive suspension and you can also simply adjust tyre pressures up or down to suit the terrain.

With its 3.5-litre twin-turbo V6 petrol engine at full go – and harnessed so smoothly through the 10-speed automatic transmission – this Lexus offers plenty of acceleration, plenty of power, and plenty of torque.

It's quiet in the cabin although there’s some wind noise from the massive wing mirrors but that's not a huge deal when the overall vehicle itself is so impressive on-road. 

Once underway, this is an easy-driving 4WD wagon. And off-road, there’s a lot of good news about the Overtrail.

It shares the same platform as the 300 Series LandCruiser and the all-new Prado and it has a lengthy wheelbase (2850mm) and a wide wheel track (1685mm front and 1690mm rear) and that means it drives with impressive composure through most off-road situations, whether it's rumbling along a corrugated dirt track or climbing a rocky hill.

Steering is well weighted and precise and there's plenty of feedback for the driver from the dirt to the steering wheel so you know exactly what's going on. And further to that you have a 360-degree camera system, so you can be exacting about your wheel placement and that maximises your chances of always being in control of the vehicle and minimises the risk of any damage.

This Overtrail has so much mechanical goodness engineered into it and so much driver-assist tech that I didn’t even need to engage the rear diff lock because through its off-road driving modes, – sand, mud, rock, snow – it just delivers the right amount of throttle response, the right amount of traction, and with the 'Electronic Kinetic Dynamic Suspension System' (e-KDSS) ticking away, working almost like a sway bar disconnect, the Overtrail is surefooted more often than not.

e-KDSS (essentially an electronically-controlled active swaybar) adjusts tension on the front and rear sway bars to suit the terrain and driving conditions. It tightens them for better body control at higher speeds on sealed surfaces, and allows for a lot more play in them when you’re off-road for improved wheel articulation through undulating terrain. It helps to get the tyres to the dirt and maintain optimum traction, maintain forward momentum – that's what it does and it does it with little to no stress whatsoever. It doesn’t even have to work hard. 

The Overtrail has decent all-terrain tyres – Toyo Open Country (265/70R18) – and even though they’re not as tough all-round as Light Truck (LT) construction all-terrains, they still provide plenty of grip and that's in a variety of off-road situations, on a variety of surfaces: sand, loose gravel, shale, even rain-soaked mud which can be very slippery and can quickly fill your tyre tread. These tyres are a handy addition to the Overtrail package and on a standard vehicle straight out of the showroom, they’re fine. 

But the news is not all good. 

The Overtrail’s 225mm ground clearance is industry standard for a larger or upper large SUV, but it isn't great for a vehicle that’s intended as an off-road beast.

And the off-road angles, approach (27 degrees) and departure (22) aren't fantastic, and rampover is not listed. Again, those measurements are industry standard for a larger and upper large SUV, but for the Overtrail, a vehicle that is supposedly an adventure machine, ground clearance and off-road angles could be a lot better. Having said that though, the underbody is well protected by some substantial bash-plates. Note: The Overtrail’s full-size spare is mounted to the underbody.

Wading depth is listed as 700mm, which is on par with its rivals.

The big side steps stick out and if you don't drive with real consideration then they'll probably cop a scrape here and there and maybe even a bit of a dent. 

One of the quirks about modern-day, large luxury 4WD wagons, such as the 300 Series, the Land Rover Defender and the Land Rover Discovery, is that the driver-assist tech onboard is so laser-precise that it almost removes the driver from the equation of actually driving. Manoeuvring one of these vehicles off-road can sometimes feel so clinical that you almost feel like you’re a spectator, that the vehicle is in control, not you. 

But what the Overtrail has in its favour is that driving it doesn't have that clinical feel about it. As the driver, you do feel dialled in to the entire experience, even though the mechanicals and tech are so very effective, you do still feel like you’re in control … and that’s how it should be.

Towing capacities are 750kg (unbraked) and 3500kg (braked). Payload is listed as 595kg, which is not a lot once you throw in your kids, dogs, and camping equipment – not to mention anything you might be towing at the time – but that payload figure is about standard for this part of the 4WD wagon market. For reference, a 300 Series LandCruiser's payload, depending on the variant, is between 650kg (VX/Sahara/GR Sport) and 785kg (GX).

The Overtrail’s listed kerb weight is 2515kg, gross vehicle mass (GVM) is 3110kg, and gross combined mass (GCM) is 6610kg.

The Lexus GX550 Overtrail does not have an ANCAP safety rating because at time of writing it has not been tested.

As standard it has nine airbags (front, side, knee and full-length driver and passenger curtain and far side driver front airbag) and driver-assist tech includes auto emergency braking (AEB) (front and rear, with day, night and intersection turning detection of vehicles, pedestrians and bicycles, plus daytime motorcycle detection), adaptive cruise control, blind-spot monitoring, lane-keep assist with lane-departure warning, front and rear parking sensors, and a 360-degree camera.

It also has road-sign assist with real-time speed limit updates, rear cross-traffic alert, adaptive high beam system and a tyre-pressure monitoring system.

Hyundai covers the Ioniq 5 with a five-year/unlimited-km warranty, which is the mainstream market norm, with a separate eight-year/160,000km warranty for the drive battery; also an expected term.

Roadside assistance and sat-nav updates are renewed annually if the vehicle is serviced at an authorised Hyundai dealer.

Service interval is two years/30,000km which is appropriate for an EV given its relative mechanical simplicity and a ‘Lifetime Service Plan’ locks in scheduled maintenance costs for the life of the vehicle.

Service cost for the first five years is $1220, with each of the two services required in that time coming in at $610. Competitive for an EV in this part of the market.

The Lexus GX550 Overtrail has a five-year/unlimited-km warranty.

Servicing is scheduled for every six months or 10,000km, whichever occurs soonest, and costs $595 each time for a total of $5950. That schedule is a little too soon for our liking.
