Kia Tasman vs Lexus GX

What's the difference?

The new Kia Tasman X-Line might not win everyone over with its styling, but as the saying goes, it’s what’s on the inside that counts. And in this case, Kia has delivered a ute that stacks up impressively where it matters most with its passenger comfort, towing ability, and on-road manners.

It also offers relative good value for the segment and plenty of thoughtful features for families and weekend DIYers. I’ve grown to like it and judging by my son’s enthusiasm, Kia has at least one very young brand ambassador already sold.

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.

If there’s one thing the Kia Tasman won’t do, it’s blend in. This ute has probably attracted more comments from my friends and family than any other car I’ve tested (and not all of them have been glowing).

With its distinctive, almost swollen curbside stance, the Tasman is a polarising sight. That said, it looks far better in person than in photos, and if you’re unsure, it’s worth giving it a proper once-over before making up your mind.

Kia has leaned hard into the bruiser aesthetic, with chunky 18-inch machined alloy wheels, large body panels, thick plastic wheel-arch mouldings, a bold grille, and a bonnet that seems to stretch on forever.

The details add to the effect, with LED projection headlights, vertical LED daytime running lights, and a handy little storage pocket above the rear wheel arch - which my son immediately claimed as a treasure box, though it’s really meant for practical items like work gloves.

At the rear, corner steps make climbing into the tray easier, but curiously, despite its 224mm ground clearance, Kia hasn’t added side steps for easier cabin access.

Step inside, and any doubts about the exterior styling may quickly fade. The Tasman’s cabin is impressive, with a spacious, premium feel that punches above expectations for a first-time ute.

There’s synthetic leather upholstery and trims, plenty of soft-touch materials in all the right places and a neat honeycomb detail framing the air vents.

The centrepiece is a sleek panoramic display set-up that combines dual 12.3-inch screens with a dedicated 5.0-inch climate control panel, giving the dash a thoroughly modern and upmarket look.

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.

The Kia Tasman impresses when it comes to passenger space. This is a genuine five-seater for adults, which is remarkable for a ute that hasn’t gone full-American-behemoth like a Ram or Chevrolet.

At 168cm (5' 6") the only small challenge for me is the lack of side steps because with its 224mm ground clearance and higher seating, climbing in and out can be a bit of a workout, especially on a slope.

Surprisingly, my eight-year-old had little trouble getting in, though he’s not always graceful on the exit. Expect to lend a hand with younger kids.

Seat comfort is excellent across both rows. Long seat bases provide proper under-thigh support and padding is generous. Both front seats are heated across three levels, though it’s a bit disappointing that only the driver’s seat is electric at this grade.

The rear bench is wide enough to comfortably fit three adults, and the flat floor ensures legroom is consistent for everyone. ISOFIX child-seat mounts and top-tether anchor points are present on the outboard seats, though there’s none in the middle, which might disappoint larger families.

Storage options are abundant, making the cabin easy to keep tidy. Up front, there are dual glove boxes - one large enough for more than just the manual and another more well-suited to a phone and wallet.

The middle console is shallow but long and features a 12-volt socket and a lid that flips over to create a picnic tray. There are a couple of generously-sized cupholders and drink bottle holders in each row, perfect if you have one of those emotional support water bottles!

The centre console also houses most of the charging options, including two USB-C ports and two wireless charging pads. There are another two USB-C ports unusually placed on the dash.

The rear offers zipped soft map pockets, device holders on the backs of the front seats, and more in the fold-down armrest.

The rear bench slides forward in a 60/40 split, and the seat bases lift to reveal 31L of storage, when accommodating the jack. Rear passengers also enjoy directional air vents, two USB-C ports and a 240-volt domestic outlet.

Technology in the cabin is mostly intuitive. The touchscreen is responsive, wireless Apple CarPlay is easy to connect, and the built-in sat nav comes with 10 years of map updates.

My only minor gripe is the climate control panel, as the steering wheel occasionally blocks it and the toggle symbols can be tricky to read.

Outside, the tray offers solid practicality with a soft-drop tailgate, full-size spare wheel, LED tray lights, and a payload capacity of 1027kg.

Tray dimensions are 1512mm H x 1572mm W x 540mm D, giving 1173L of storage, plus an extra 240-volt domestic outlet for DIY or worksite convenience.

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.

All Kia Tasman variants are powered by the same 2.2-litre, four-cylinder turbo-diesel engine, producing 154kW of power and 440Nm of torque.

That places it close to its Isuzu D-Max counterpart in terms of output, though Ford and Toyota rivals still offer slightly higher torque which is something to consider if you’re planning to tow larger toys or heavy trailers.

The X-Line holds its own with a 3.5-tonne braked towing capacity, a rear differential lock, and three terrain modes ('Snow', 'Mud' and 'Sand') for added confidence off the beaten track.

Kia has also included a clever ‘Tow Mode’, accessible via its own menu under Trailer on the media display. This feature allows you to select the weight range of whatever you’re towing, which fine-tunes the driving experience, especially how the eight-speed automatic shifts under load.

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. 

The X-Line claims an official combined fuel consumption of 7.8L/100km and comes with a generous 80L fuel tank, giving it a theoretical driving range of around 1000km.

In real-world use, a mix of school runs, grocery trips, and a few longer drives, I recorded 8.8L/100km, which is a strong result for a ute of this size and capability.

Of course, this figure doesn’t account for towing a trailer or fully loading the tray, but for everyday family life, the Tasman strikes a good balance between power and efficiency. It’s the kind of ute you can happily drive all week without constantly hunting for a fuel station.

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.

The X-Line has enough power to feel confident on the open road, though I’d have liked a touch more grunt for overtaking or quick acceleration.

The eight-speed automatic shifts smoothly most of the time, but occasionally drops out of lower gears a bit too quickly, giving a slightly luggy feel when you need an extra burst of speed.

The higher ride height has its pros and cons. Visibility is excellent and you can see the road ahead clearly but it can act a bit like a windsail on the highway, pushing the ute around in strong crosswinds. There’s some roll through corners, though less than I expected.

A practical consideration for families is that from the driver’s seat, it’s often tricky to see small children or pets near the car, so vigilance is key when they’re outside the vehicle!

Ride comfort is decent for a ute. The Tasman absorbs most bumps with ease, though it’s not always perfectly poised on rougher surfaces. Overall, it’s a comfortable open-roader and the cabin remains relatively quiet despite the rumbling turbo-diesel engine.

At over 5.4m in length with a 12.3m turning circle, manoeuvring takes a bit of planning. Thankfully, the 360-degree camera system, along with front, side, and rear parking sensors helps a lot, though I feel more comfortable backing in than reversing out of tight spaces.

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 Kia Tasman comes with a seven-year, unlimited-kilometre warranty, which is a solid term for the class.

Complementing that is a seven-year capped-price servicing plan, with services averaging $610 per visit. That’s a little higher than some rivals.

For context, the Ford Ranger averages $399, the Toyota HiLux $580, and the Isuzu D-Max $449 per service but it does include roadside assistance if you service through a Kia dealership.

Services are spaced every 12 months or 15,000km, whichever comes first. With around 162 Kia service centres across Australia, city and regional owners are reasonably well covered.

Overall, the Tasman offers relatively straightforward ownership, even if servicing isn’t the cheapest in the segment.

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.
