What's the difference?
The new Lexus GX 550 showcases a brand new design for its third-generation iteration but the model is new to the Australian market.
And while it hasn't been as hotly anticipated as its cousin, the Toyota Prado, it's still one that should excite. It's a capable full-time four-wheel drive that manages to look good on- and off-road! It feels like a breath of fresh air.
Will it find itself more likely adorning the garage of a city slicker? Perhaps, but you can't deny it has some star power now with its design and it couldn't have come soon enough. Especially when you compare the flagship Sports Luxury grade my family and I have on test to its European luxury rivals, the BMW X7 and Land Rover Defender.
Since its launch in the 1960s, the iconic HiLux has been one of Toyota’s strongest-selling models. The current eighth-generation continues that tradition, even though now in its ninth year in local showrooms and having lost its long-held 4x4 sales leadership to Ford’s Ranger.
Toyota has done a commendable job in keeping the HiLux looking fresh since its local launch in 2015, with numerous cosmetic/equipment updates and the addition of prestige models like the wide-track Rogue and performance-enhanced GR Sport.
The 4x4 HiLux’s latest upgrade is the first use of Toyota's new 'V-Active' 48V technology, which provides electric assistance to the diesel engine. Toyota claims improved fuel efficiency, acceleration and smoothness, along with enhanced off-road prowess. We recently put one to the test to see how it measures up from a tradie’s perspective.
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.
The HiLux’s age-defying sales and resale values confirm it’s still one of the top two 4x4 dual cabs on the market. However, its new V-Active technology feels underdone, as it adds weight (we reckon about 40kg) and complexity without gains in performance you can feel or economy you can meaningfully measure. Hopefully, Toyota’s next crack at a 'hybrid' HiLux will be more convincing.
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 HiLux’s enduring appeal is the ‘unbreakable’ feel when you step aboard. Even though its curvaceous styling is increasingly dated, we can’t fault the build quality as it displays a peerless standard of fit and finish which never wavers.
Our only major gripe (since its launch in 2015) is the cramped rear seating. It’s particularly tight for tall people, giving that I’m 186cm and when sitting in the rear seat with the driver’s seat in my position, my knees are pressed into its backrest and my head rubs on the roof lining.
Shoulder room for three large adults is equally challenging and tolerable only for short trips. We reckon the Ranger’s more accommodating rear stalls are significant in its sales leadership.
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.
With its 2150kg kerb weight and 3050kg GVM, the SR5 V-Active has a 900kg payload rating. It can also tow up to 3500kg of braked trailer but with its 5850kg GCM (or how much it can legally carry and tow at the same time) that would require a substantial 700kg reduction in payload to only 200kg, which could be used up by a driver and passenger alone.
Alternatively, you could lower the trailer weight limit by the same 700kg to 2800kg (which is still a sizeable trailer) and retain the SR5’s maximum payload. We reckon most owners would do this anyway, given few (if any) would need to tow 3500kg.
The load tub is 1570mm long, 1645mm wide and 495mm deep with 1105mm between the wheel housings. Therefore, it can’t carry a standard Aussie pallet but will take a Euro-sized one. There are four load-anchorage points and we welcome the new lower/raise assistance for the hefty tailgate.
Cabin storage includes a large-bottle holder and bin in each front door, plus pop-out cupholders on either side of the dash, upper and lower glove boxes (with the upper having access to air-con) and an overhead glasses holder.
The latest centre console layout has a wireless phone-charging pad and vertical phone-storage slot, small-bottle/cupholder, a bin for small items and a box with padded lid that doubles as an elbow rest.
Rear passengers get a bottle-holder and bin in each door, pockets on each front seat backrest and a fold-down centre armrest with two more cupholders.
Only the narrower driver’s side of the 60/40-split rear seat base-cushion can swing up and be stored vertically as the passenger-side is now fixed, given the V-Active’s 48V battery resides beneath it and is ventilated by a louvered air intake in the passenger footwell.
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 new electrically-assisted drivetrain is available only in SR/SR5 4x4 dual cabs and the Rogue, paired with the HiLux’s ubiquitous 2.8-litre four-cylinder turbo-diesel and six-speed automatic.
Our SR5 V-Active 48V test vehicle has a list price of $63,260. It’s also equipped with the optional premium interior package, which for an additional $2500 adds black leather-accented seats and door trims, heated front seats and an eight-way power-adjustable driver’s seat. Its eye-catching 'Nebula Blue' premium paint option adds another $675.
Latest MY24 updates feature a redesigned front fascia with black ‘honeycomb’ grille, plus wireless phone charging, two USB-C ports in the centre console for rear seat passengers to use and a tailgate equipped with gas-struts to ease opening/closing effort.
Otherwise, it’s the same SR5 with which we’ve grown very familiar. Standard equipment includes 18-inch alloys and 265/60R18 tyres with a full-size alloy spare, along with LED lighting, side-steps, sports bar, privacy glass and more, even though Toyota still won’t throw in a tub-liner.
Inside is remote keyless entry/start, dual-zone climate, an air-conditioned cooler box, multiple USB ports/12-volt sockets and a 220-volt outlet, premium-grade steering wheel and shifter-knob, driver’s 4.2-inch colour multi-info display, a 360-degree camera view and more.
The 8.0-inch touchscreen for the multimedia system, including six-speaker audio, appears to shrink as each year passes, but is easy to use and offers multiple connectivity including Apple CarPlay/Android Auto and digital radio. It also projects imagery for the various camera views.
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 venerable (1GD-FTV) 2.8 litre four-cylinder turbo-diesel with V-Active produces the same 150kW and 500Nm as the standard engine, driving through a six-speed torque converter automatic.
However, Toyota claims fuel economy gains of up to 9.5 per cent when this drivetrain is combined with the new hybrid technology, which comprises a 48-volt electric motor-generator, 48-volt lithium-ion battery and idle-stop system.
The turbo-diesel engine uses a silent-belt to drive the motor-generator, which charges the battery under the rear seat. This battery, which Toyota claims weighs less than eight kilograms with 4.3Ah capacity, also supplies electricity to the vehicle’s 12-volt system through a DC/DC converter.
This system can send up to 8.4kW of power and 65Nm of torque through the motor-generator to assist the engine. Toyota claims this delivers smoother and quieter yet more responsive performance and reduces engine load under acceleration. It also results in a small reduction in idle speed from 720rpm to 600rpm.
Deceleration and braking energy are also recovered, converted into electricity and stored in the 48V battery for later use. Toyota claims “hydraulic braking combined with regenerative braking creates a more effective and natural deceleration feel and supports downhill manoeuvring.”
The idle-stop system does not use the starter motor like conventional set-ups. Instead, the electric motor-generator, which is permanently connected to the engine via its belt-drive, delivers this function with greater smoothness and quietness.
Idle-stop duration can also be extended by the driver and, when restarting the engine on inclines, the idle-stop system retains brake pressure until enough drive force is generated to ensure smooth acceleration.
In another first for HiLux, its part-time, dual-range 4x4 system (with switchable rear diff-lock) in V-Active variants is paired with 'Multi-Terrain Select' to enhance off-road ability.
The driver can switch between six traction control settings tailored to suit a variety of terrain including 'Auto', 'Sand' and 'Mud' (high- and low-range), 'Deep Snow' and 'Dirt' (high-range) and Rock (low-range).
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.
We completed a total distance of 580km, which comprised a mix of city and suburban driving with an empty load tub and up to four adults on board, plus some freeway/highway running with a near-maximum payload.
When we stopped to refuel at the end of our test, the dash display was claiming average combined consumption of 9.5L/100km, which was lineball with our own 9.4 figure calculated from fuel bowser and tripmeter readings.
Both are higher than Toyota’s official 7.2L/100km figure but within the usual 2.0-3.0L/100km discrepancy between OEM ratings and real-world figures.
Interestingly, the last time we tested a 4x4 SR5 auto dual cab ute (without V-Active) in 2023, using similar routes and payloads, we achieved 9.6L/100km. So, the V-Active’s drop in consumption was only about 2.0 per cent, compared to Toyota’s claim of up to 9.5 per cent.
So, based on our real-world figure, you could expect a useful driving range of around 870km from its 80-litre tank.
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.
If you’re expecting a tangible difference in performance with the V-Active system, you’ll probably be disappointed. Fact is, after almost 600km of testing, on a variety of roads with a variety of loads, we could not detect any noticeable gain in acceleration, braking or smoothness compared to a standard SR5.
That’s not to say the V-Active system is not delivering up to 8.4kW of power and 65Nm of torque, as Toyota claims. It’s just that these gains are modest and delivered so discreetly that they are undetectable in real-world driving.
This was perhaps best demonstrated when we loaded 650kg into the load tub, which when combined with our two-man crew was a total payload of 830kg. That was only 70kg shy of the payload limit.
It made light work of our 13 per cent gradient 2.0km set climb at 60km/h by self-shifting down to fourth gear at 2250rpm, where it tapped maximum torque to easily haul this payload to the summit.
However, in our previous test of a standard SR5, on the same incline with 100kg more payload, the gear selection and engine rpm were the same as the V-Active. The same applied to engine-braking on the way down.
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 HiLux achieved a maximum five-star ANCAP rating in 2019, so its six-year validity will expire next year. Even so, there are seven airbags plus AEB with pedestrian and daytime cyclist detection, blind-spot monitoring, rear cross-traffic alert, lane keeping, active cruise control, speed-sign recognition, panoramic view/reversing camera and more.
The rear seat offers ISOFIX child-seat mounts on the two outer seating positions plus top-tether restraints on all three seating positions.
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.
Toyota covers the HiLux with a five-year/unlimited km warranty which is par for the course in the mainstream market.
Service intervals are relatively short at six months/10,000km whichever occurs first. Capped-price servicing for the first five years/100,000km totals $3889 or an average of $779 per year.
