Kia EV6 vs Lexus Gx550

What's the difference?

It’s fair to say the Kia EV6 is not the most affordable mid-to-large electric SUV money can buy. Especially in the era of cheaper Chinese models.

It also lacks some of the practicalities of a few rivals. If that’s your focus and you’re dead set on buying a Kia, then the EV5 is the clear choice.

But that’s not the sole purpose of this car.

It doubles as family transport and a car for driving enthusiasts. It’s the sort of EV that can convert EV non-believers.

After a week with the EV6, it’s not a car I’ll forget easily. And I urge buyers looking in the EV space not to overlook this pioneering model. It’s a brilliant car to drive and the GT-Line RWD is the value pick of the whole line-up.

The new Lexus GX 550 Sports Luxury looks fantastic and has enough mod cons to satisfy a family but it’s not as luxurious as you’d expect from a premium brand and the fuel economy and driving range will turn off some. But if you’re still interested, there’s a lot here that will make you happy and it’s one of the smoothest 4WDs I’ve driven.

When I first saw the Kia EV6, I have to admit I wasn’t a massive fan of the design. I was, and still am, a massive fan of the mechanically related Hyundai Ioniq 5. Perhaps one of the many reasons that model won Best Medium SUV Under $130,000 at the 2026 CarsGuide Car of the Year Awards!

But the 2026 facelift has given me a renewed appreciation of the Kia’s design.

The overall shape is the same but the front, which was arguably its least appealing angle, has been redesigned.

It’s 15mm longer thanks to the new front bumper design, and it has adopted a completely new headlight signature that's in keeping with the EV3, EV4, EV5 and EV9. The front looks meaner, more aggressive, but in a really hot way.

There’s also a new bumper at the rear but the tail-lights are pretty much the same.

Overall it’s a much sharper look, helping to breathe new life into the EV6.

The visual changes are more subtle inside, but it was already a nice cabin to begin with. The big changes include the new version of Kia’s dual-screen set-up which is more modern and centred than the previous version, and there’s more visually appealing graphics.

The other key change is the steering wheel. For GT-Line and GT grades, Kia’s dropped the polarising two-spoke wheel in favour of a sportier and more premium three-spoke, dual-tone wheel found in other models, including the EV3. The base Air retains the two-spoke wheel.

The new GX 550 looks massive and while it shares the same platform as the Toyota LandCruiser 300 series, it doesn't share all of its bulk. They both stand at 1980mm wide but differ on length (5015mm vs 4980mm) and height (1670mm vs 1950mm), respectively.

The new design is fabulously rugged but each body panel looks meticulously crafted and is just the right size. This just means the proportions look right and your eye sort of glides over the big body rather than stopping on any one feature.

But having said that, there are a lot of nice features to focus on, like the long LED headlights and rear strip light, auto-folding side steps, 22-inch alloy wheels and sharply styled rectangular side mirrors.

The tailgate window can also be opened if you need to pop something into the boot but don't want, or have the space, to open the tailgate itself.

The styling takes a minor nose dive once you hit the cabin, though, because it doesn't look as sumptuous as you'd expect in a premium SUV.

I love the utilitarian and military vibe of the vertical dashboard, chunky air vents and relatively small windscreen. It looks great but some trims are plasticky and the touchpoints, while soft, are not Lexus-plush.

However, the technology looks gorgeous with an integrated 14-inch multimedia display and a 12.3-inch digital instrument cluster. The fixed sunroof with its two settings (clear or opaque) is also a lovely feature.

But on a whole, the GX 550's European rivals outclass it with their flashier cabins.

Under Australia’s vehicle categorisation, the Kia EV6 is classed as a large SUV. Which is not correct. Yes, it’s long and wide but it isn’t large. It’s medium. Also, is it an SUV? Or is it a low-slung coupe-style fastback? Perhaps a bit of both.

The EV6 has a decent amount of space in the cabin, but family-friendly practically might not be its strongest suit.

In the front row, headroom is limited. The sunroof is partly to blame for this, but the EV6’s front seats have always felt a little cramped for taller folks. Finding my perfect driving position took a bit longer as a result. Popping your sunglasses on your head is a no-no for a six footer like me. There is, however, plenty of space across the front of the cabin.

The front seats offer excellent upper body bolstering but could do with a little more for the thighs. But they are delightfully comfortable and look gorgeous.

The elevated centre console provides a high-set armrest and under that is a massive central bin, then there is a huge amount of open space underneath.

It houses two shallow and narrow cupholders with a phone charger, gear shifter, vehicle on/off and seat/steering wheel heating buttons. Yay buttons!

Climate control is managed via a digital panel separate to the main screen. It features smart dials that switch between air con and audio and sat-nav controls. Speaking of which, the air con flow is excellent.

Kia’s updated multimedia system brings it into line with other newer models. It’s a pleasure to use this system. Large tiles drill down into logical sub-menus, you can swipe every which way and the resolution is excellent. It’s also easy to navigate.

There are three USB-C charge ports under the centre stack.

Taller passengers might need to duck their head when getting in the second row, due to the lower sloping roofline. Once seated, the EV6 features that quirk of some older EVs where the rear seats are heavily bucketed and your knees sit up high because of the positioning of the under-floor battery. A lot of newer EVs keep the rear footwell free of battery packs to ensure more foot room and a more comfortable rear-seat experience.

There’s heaps of leg room behind my seating position, and headroom isn’t bad back there. It’s certainly better than the front. I had about 2.0cm between my head and the roof liner.

It feels a little dark back there due to the high window line, privacy glass and small rear window.

The rear seats are comfy but on the firmer side. There’s a fold-down arm rest with two shallow cupholders, and a small bottle will fit in the door.

You get two map pockets, USB-C ports on the back of both front seats, and chest-level side air vents.

You can lower the 60/40 split rear seats via a lower lever on the seat base. They fold almost flat, too. You can also lower the seats via a lever in the boot which is a handy feature.

The EV6 Air RWD’s boot can swallow 490 litres of cargo, and that drops to 480L for all other grades.

The boot area allows for a decent amount of usable space but the sloping tailgate means you won’t fit tall items.

Under-floor storage is limited but could easily fit flatter items like a charging cable. It also houses the tyre repair kit which is sadly what you get instead of any form of spare wheel. The boot also has a number of bag hooks, speakers and a light.

A front storage compartment under the bonnet can take 52 litres in the RWD grades, dropping to 20L in AWD versions.

The cabin of the new GX 550 is fairly practical with plenty of head- and legroom in each row (yep, even the third!). When you first hop in, it can feel a big snug on elbow-room but this feeling quickly dissipates.

Despite a 215mm ground clearance, access is pretty good for the front and middle rows due to the wide door apertures and side-steps. Third row access is a bit awkward for an adult but my eight-year old loved scampering back there this week.

The electric front seats are comfortable with their extra functions and I like the way the massage feature extends to the seat cushion as it limits fatigue on longer journeys. However, you sit on top of them rather sink into them which makes it feel a little trucky at times.

The wide middle row has a bench seat that will be comfortable for kids but an adult might get a sore behind on a long trip. The transmission tunnel also compromises foot room for adults but the seat is wide enough to make use of all three top-tether anchor points (there are ISOFIX mounts too).

It was a little bit of an effort to lift my big booster seat into the back because the GX 550 sits so tall but otherwise, there's plenty of room around a child seat for them not to feel like a sardine.

Individual storage is made up of a glove box that fits an owner's manual, a small shelf in the dashboard and a middle console that doubles as a cool box (mini fridge) and can fit up to four cans or bottles in it.

Each row gets four drinkholders and two USB-C ports but the front also enjoys a 12-volt socket and wireless charging pad. There's a 220V domestic plug port in the boot for larger appliances, too.

It's sometimes awkward to use the wireless charging pad because it's easy for your phone to slide around on it and it quite often disengaged from charging.

My son enjoyed all of the other amenities in the middle row, like the reading lights, climate control, two USB-C ports and retractable sunblinds and I applaud carmakers when they position rear directional air vents in the pillars and/or roof. It just makes it so much easier to cool down sweaty kids!

The 14-inch multimedia display has clear graphics and a responsive touchscreen. The layout is easy enough to get used to after spending some time with it and the sat nav is simple to use.

I like that the sat nav directions can be pulled into the 12.3-inch digital instrument cluster and head-up display.

There is a Lexus connected services app, which you get a three-year subscription to. It's easy to connect to the wireless Apple CarPlay and there is also wireless Android Auto.

The system also has Bluetooth and digital radio, which is a delight to use through the 21-speaker Mark Levinson sound system.

The cabin is rounded out by the well-shaped boot which has a massive 1063L of capacity when the third-row is folded. That's been more than enough for my family's needs this week and my German Shepherd was pretty comfy back there, too. The powered tailgate has a kick-function and there is a full-size spare wheel underneath the car.

The Lexus GX 550 shares the same platform as the recently introduced Toyota Prado but both models are now based on the same 'body-on-frame' platform shared by the beastie Toyota LandCruiser 300 Series. So it's bigger and features a more rigid chassis than before.

Surprisingly, that hasn't translated to a massive price tag for the GX 550 and you can pick up the flagship grade on test for this review for $128,200, MSRP.

Which sounds inexpensive when you compare it to the BMW X7 xDrive 40i M Sport which is priced from $171,300 MSRP but the Land Rover Defender 110 P400 X-Dynamic HSE is a lot closer at $128,815 MSRP.

The only issue here is that shared platform, because while they don't share the same powertrain, the flagship Toyota Prado Kakadu ($99,990 MSRP) is still almost $30K more affordable and boasts a similar equipment list. So, ask yourself, is it the brand and engine you're after or the new good looks?

The standard equipment is well-rounded with a 14-inch touchscreen media display with satellite navigation and wireless Apple CarPlay and Android Auto.

A fully digital 12.3-inch instrument cluster, colour head-up display, three-zone climate control and a 21-speaker Mark Levinson sound system round out multimedia requirements.

Other technology includes a digital rear view mirror, two USB-C ports in each row, a 12-volt socket, a 220-volt domestic outlet and a wireless charging pad.

There are two particularly handy features for families, the 'cool box' (basically a mini fridge) middle console and rear retractable sun-blinds.

The fixed panoramic sunroof features two settings allowing you to make it clear or opaque. The electric front seats feature heat, ventilation and massage functions and the rear outboard seats are heated as well. The third row electrically adjusts and there are multiple buttons throughout the car to access this feature.

Upgraded leather-accented upholstery is standard in the flagship grade and is available in three combinations. The Sports Luxury also features 22-inch alloy wheels, a full-size spare wheel and a powered tailgate with kick-function.

The EV6 has a range of powertrains depending on the grade. The Air and GT-Line RWD have a single motor set-up offering 168kW of power and 350Nm of torque, and the GT-Line AWD dual-motor pumps out 239kW and 605Nm.

Kia has boosted power in the high-performance GT by 18 kilowatts to a bonkers 448kW.

These figures are higher than some cheaper rivals and on par with other similarly priced EVs.

The 0-100km/h sprint time for the rear-drive grades is 7.7 seconds, dropping to 5.3 seconds for the GT-Line AWD, while the GT can do it in a blistering 3.5 seconds when engaging Launch Control.

All GX 550 grades share the same 3.5L V6 twin turbo-petrol engine which produces up to 260kW of power and 650Nm of torque.

This 4WD has high- and low-gearing, as well as a bunch of driving modes to suit most occasions, like 'Eco', 'Comfort', 'Sport' and 'Sport+'.

The 10-speed automatic transmission shifts through its gears smoothly and it always feels like it's engaged in the right gear. Which isn't always the case for a big SUV!

The Sports Luxury is fitted with a towing hitch and cover but unlike the base Sports grade which has a 3.5-tonne braked towing capacity, this model only has a 3130kg capacity which might not appeal to families with big toys to tow. 

All EV6 grades get a bigger under-floor lithium-ion battery, up from the 77.4 kilowatt hour unit in the previous model to 84kWh.

Driving range is up more than 50km in rear-wheel drive variants to 582km in the Air and 560km in the GT-Line, according to the WLTP testing cycle.

The GT-Line AWD’s range is now 522km (up from 484km), and the range-topping dual-motor GT offers 450km of range - a 26km increase.

All EV6 grades have vehicle-to-load charging via a port under the rear seating row or by using an extender for the external CCS Type 2 charging port.

Maximum DC charging is 10.5kW but the EV6 supports AC charging infrastructure up to 400 and 800 volts.

Using a 50kW fast charger should take 80 minutes to get from 10 to 80 per cent full, while a 350kW charger takes 18 minutes. Slow AC charging at home with three-phase power should take about seven-and-a-half hours.

Official energy consumption varies between grades. The Air RWD is 15.9kWh/100km, GT-Line RWD is 16.9kWh, GT-Line AWD is 17.7kWh and GT is 20.9kWh.

The car’s trip computer recorded an efficiency figure of 19.1kW/h when I handed it back, but I engaged in some enthusiastic driving. Factoring in the usable battery capacity (80kWh), the EV6 GT-Line RWD’s theoretical range is 473km.

It has multi-mode regenerative braking that is exceptionally smooth, including one-pedal driving, various EV sounds to choose from and a utility mode function to save battery life.

There’s even a soft close function for the charge flap that’s integrated nicely in the driver’s side rear tail-light.

I didn’t have high hopes for fuel economy because the official combined (urban/extra-urban cycle figure is a hefty 12.3L/100km but after mostly open-road driving, with some urban stuff mixed in, my real-world average came in at 11.8L.100km! This figure is based on my actual km travelled (358km) and litres of fuel used (42.41L).

While I’m surprised by the fuel usage result, I wouldn’t say this car has good fuel economy compared to its diesel-powered counterparts but it’s not terrible!

The GX 550 has a relatively small fuel tank compared to its Toyota cousins at 80L and based on the combined fuel cycle, you’ll get a theoretical driving range of up to 650km.

Not all that great. Not for a big family mover and not if you’re typically driving in the city, where fuel usage will be a lot higher.

The GX 550 only accepts premium unleaded petrol (95 RON), too.

This is where the EV6 excels. There’s a lot more competition out there now, but the good news is the EV6 still impresses on the road.

I am purely focusing on the GT-Line RWD for this section as it’s the grade I had for a week.

It’s not brutally quick from a standing start, but it offers a nice, linear build up of speed. It adds speed quite quickly when at pace and this is more than enough poke for most people.

If you are intent on more power and speed, but without stretching to the GT flagship, the GT-Line AWD might be your cup of Jarrah. Although that is an $8000 premium over the RWD.

If you want to save the cash the RWD has drive modes ('Eco', 'Normal', 'Sport', 'Snow', 'MyDrive'), so you can add some spice with Sport mode.

The EV6’s precise steering has a little weight to it and good feedback.

On dynamically engaging roads the EV6 doesn’t feel its two-tonne weight. It has loads of grip when you lean into a corner and remains flat through the twisty stuff. There’s the tiniest hint of lateral movement in the car but there’s a lack of top-heavy body roll.

Thanks to the rear-wheel drive configuration, it’s also playful. The rear flicked out briefly when turning in wet conditions, but otherwise the stability control keeps everything in check.

This car has clearly been engineerd by driving enthusiasts for driving enthusiasts.

The ride quality is a little jittery on uneven roads. It’s not cushy like the EV5. You will feel tram/train tracks, potholes and random bumps. I detected a little vibration through the steering wheel on crumby roads. The Continental Premium Contact 6 (255/45 R20) tyres have a decent sidewall but they can’t soak up everything.

As well as being dynamically excellent, it’s also a lovely cruiser on smooth freeways and roads.

Other related points - it has a large turning circle (11.6m) and visibility is impeded by enormous B- and C-pillars, small rear windows and a middle-seat headrest.

Oh my goodness the Sports Luxury is a masterclass on 4WD refinement! You never feel the bulk or weight of this massive SUV when you’re driving it. The power delivery is effortless and there’s lots of grunt available when you hit hills.

The handling is also very good with responsive steering and enough road feedback as a driver to make you feel comfortable with what the car is doing. There is some roll in corners but it can tackle more corners at speed than I thought it would. 

The high driving position makes me feel like I can see a long way ahead yet while visibility is mostly good, it can be compromised when you have the side window shades and the third row headrests up. Which is why I love the digital rear view mirror.

Overall, ride comfort is good with forgiving suspension and low cabin noise, even at higher speeds. It’s pretty easy to chat with all rows and there’s not a lot of engine noise which adds to the refinement. I do like hearing a V6 rumble but that’s just a personal preference. 

I was a little worried about hitting my local Westfield car park but this is a nimble SUV to manoeuvre and parking it is a breeze with the 360-degree camera system and parking sensors. 

The new GX 550 hasn’t been tested by ANCAP and is unrated but its cousin, the Toyota Prado, which shares the same platform just achieved a maximum five-star rating from assessment in 2024. It's fair to expect a good result for this model.

Overall, the Sports Luxury has a long list of standard safety equipment and features nine airbags which is good for a family SUV. 

Safety equipment includes adaptive cruise control, lane departure alert, lane keeping aid, traffic sign recognition, emergency steering assist, driver monitoring, safe exit assist, emergency call functionality, blind-spot monitoring, rear cross-traffic alert and tyre pressure monitoring.

The GX 550 has autonomous emergency braking (AEB) with pedestrian, cyclist, motorcyclist and junction turning assist.

The EV6 is covered by Kia’s solid seven year/unlimited kilometre warranty and it has a battery warranty of seven years or 150,000 kilometres, whichever occurs first.

The service schedule is every 12 months or 15,000km.

Kia offers service plans of three, five and seven years with pricing for Air and GT-Line of $728 for three years, $1391 for five years and $2055 for seven years.

The GT is a little pricer at $842, $1570 and $2319, respectively.

This pricing isn’t astronomical, but it is more expensive than the Cupra Tavascan and MG IM6.

Kia has 147 dealerships across the country covering metro, urban and rural areas and all of them service EVs.

Lexus offers the GX 550 with a five-year/unlimited km warranty, which is fairly standard compared to its Euro rivals.

You get five years capped-priced servicing which costs $5950 but the servicing schedule is a bit of a bear at every six months or 10,000km, whichever occurs first.
