Lexus Gx550 vs Land Rover Discovery

What's the difference?

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 Land Rover Discovery 35th Anniversary Edition drives beautifully, with effortless power and a composed, comfortable ride. It’s elegant and well-equipped for its price, though the technology often frustrates, and it’s not as spacious as some seven-seater rivals. Small quirks in everyday use prevent it from fully standing out in a competitive segment but it does enough to be considered.

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 Discovery remains a handsome SUV. It isn’t as boxy or rugged-looking as some of its rivals, but it still carries a quiet confidence and a hint of adventure in its stance. The 35th Anniversary Edition gets a few subtle touches to help it stand out, including 21-inch black alloy wheels, roman-numeral anniversary badging and slim LED lighting signatures that give it a clean, sophisticated look.

Inside, everything feels solid and thoughtfully put together, with soft-touch materials in all the right places. Some of the trim finishes lean a little synthetic, but the leather upholstery is beautifully done and the dual sunroofs bring in plenty of natural light, which helps elevate the cabin ambience.

The 11.4-inch media display takes pride of place on the dash and looks premium, and there are enough physical buttons and dials to satisfy those who like some tactile-functionality. That said, the cabin doesn’t quite deliver that sense of occasion you might expect at this price. It’s nice, it’s just not especially distinctive.

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 Discovery’s cabin is an interesting mix - at first glance it seems to offer the right balance of space and features, but once you settle in, a few small disconnects between technology and layout become apparent.

Up front is where you want to spend most of your time. The powered seats are well-padded with long bases and excellent lumbar support. There’s plenty of room for tall drivers and passengers and elbow space is generous. The only annoyance is the heated seat function, which is buried behind the menu system and the fiddly climate dials.

The middle row highlights the Discovery’s tall-but-narrow proportions. Adult passengers can feel a little cramped side-to-side, though the flat floor gives decent leg and foot room. The third-row surprises with wider seats and deeper footwells than expected, so knees aren’t pressed against chests. Access, however, is more suited to children than adults.

Storage is abundant and thoughtfully positioned. Up front, there are dual glove boxes (one lockable), a hidden cubby behind the climate panel and underneath the sliding cupholders, a tray housing the wireless charging pad (which, in our test car, didn’t work), and the middle console fridge which is a handy touch for keeping snacks or drinks cool on long trips. The middle row gets map pockets, cupholders and bottle storage, while the third-row benefits from hinged cubbies on each wheel arch.

The boot is the standout, offering a massive 1137L when the third row is folded. Its tall and deep shape makes it practical and features like the powered tailgate, adjustable boot-lip height via air suspension, a full-size spare and a 12 volt socket round out its friendly usability.

Access is a simple step-in and step-out scenario thanks to the Discovery’s 'Auto Comfort Access' mode which, when activated, lowers the vehicle when parked. That said, the doors are heavy and need a firm push to latch properly.

Technology is a bit of a mixed bag. The media system is somewhat intuitive once you spend time with it, but newcomers may find the layout confusing. It includes sat nav, wireless Apple CarPlay, and Android Auto, though in our test car, CarPlay occasionally showed music playing without sound but re-pairing my iPhone 15 Pro Max fixed the issue. The dual-use climate dials, which control temperature, fan speed and seat heating, can feel finicky, and one rear door locked itself for four days despite troubleshooting. The rear seat fold controls also worked inconsistently.

On the plus side, amenities like four-zone climate control, multiple air vents per row, and seven USB ports scattered throughout the cabin are thoughtful touches.

Since the launch of the 35th Anniversary Edition, the Discovery line-up has shifted, now trimmed to five diesel-powered grades. Originally based on the Dynamic SE, this special edition is based on the Gemini variant which is second from the top of the range.

Pricing starts from $132,090 MSRP, placing it above key rivals like the Lexus GX 550 Luxury ($112,607) and Toyota LandCruiser Prado VX ($87,400). In other words, it’s priced right in the middle of the family-luxury SUV battlefield.

Inside, you get heated and powered chairs up front with four-way lumbar, plus heated outboard second-row seats. There’s no heated steering wheel or front seat ventilation, which feels like a miss at this price point, but the equipment list remains generous. Standard highlights include an 11.4-inch media screen, satellite navigation, dual sunroofs (one fixed), wireless Apple CarPlay and Android Auto and a premium Meridian sound system.

Family practicality is well-covered with a hands-free powered tailgate, adjustable load height, full-size spare wheel, 360-degree camera system, five USB-C ports, two USB-A ports, two 12-volt sockets and directional vents in every row. You also get seating flexibility and family-friendly safety points: four ISOFIX mounts and five top-tether anchors across the back rows.

The Anniversary Edition builds further with rear privacy glass, a Wi-Fi-enabled media system (with data plan), colour head-up display, power-tilt/fold second-row seating, tow pack (including hitch receiver and tow assist), anniversary badging, black roof rails, centre console 'fridge' and four-zone climate control.

Our test vehicle also features the 'Capability Plus Pack' ($4910), which adds meaningful off-road hardware like a rear differential lock, twin-speed transfer case (high/low range), multi-terrain modes (including 'Grass', 'Gravel', 'Snow', 'Mud-ruts' and 'Rock Crawl') and a wading sensor. Land Rover’s 'All-Terrain Progress Control' (essentially a low-speed, off-road cruise control) is also included.

It offers a well-rounded feature set that keeps it competitive, though a handful of additional premium touches would elevate it to a more commanding position in the segment.

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 35th Anniversary Edition runs a hefty 3.0-litre, six-cylinder, twin-turbo diesel paired with a 48V mild-hybrid system. Together, they produce 257kW and 700Nm. It’s brisk, too, with a 0-100km/h sprint time of 6.3-seconds, which is impressive for such a large 4WD.

Towing is rated at 3.5 tonnes and wading depth sits at 900mm, reinforcing its credentials as a proper adventure vehicle. Our test vehicle also features the 'Capability Plus Pack', which brings low-range gearing, rear differential lock and multiple terrain modes.

Not too bad for something that looks more like a school-run luxury SUV than some of its rivals.

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 35th Anniversary Edition has a claimed combined fuel figure of 7.8L/100km, and with its 89-litre tank you’re looking at a theoretical driving range of around 1141km. In the real world, I saw 9.0L/100km - that’s with one longer highway run mixed into a week of school runs and suburban errands.

It’s a touch thirstier than I’d hoped given I wasn’t towing or carrying heavy gear, but it still sits comfortably within expectations for this segment and size of vehicle.

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. 

Power delivery in the Discovery feels effortless, with none of the laggy, heavy character you can get from some big diesels. It responds quickly when you need it to, whether you're merging into traffic or overtaking and always feels like it has plenty left in reserve.

Ride comfort is excellent. The adaptive suspension absorbs bumps and settles the body confidently through corners without feeling floaty or wallowy. Steering has a reassuring weight to it - not too light, not too heavy - which helps the Discovery feel sure-footed and composed on the road.

The cabin is impressively quiet, making it easy to chat with passengers across all three rows and reducing fatigue on longer drives. Visibility is generally strong and the high seating position gives a good command of the road. The only drawback is the middle-row headrest, which blocks the rear view. A digital rear-view mirror would be a helpful addition, especially when the car’s full.

Despite its size, the Discovery is surprisingly easy to manoeuvre, with a fairly forgiving 12.7-metre turning circle. Parking is straightforward thanks to a clear 360-degree camera system, although the display itself could be larger. Even in tight shopping centre car parks it never feels unwieldy.

The new Discovery hasn’t been tested by ANCAP yet and is unrated but it does come with a large suite of safety features and eight airbags which is good to see on a large 4WD.

Standard equipment includes autonomous emergency braking, blind-spot monitor, driver attention monitor, lane keeping aid, rear collision alert, rear cross-traffic alert, traffic sign recognition, speed limit warning, intelligent seatbelt warning, powered child locks, front/rear parking sensors and a 360-degree view camera system.

The adaptive cruise control is well-calibrated as it slows smoothly behind traffic and confidently builds speed again once the lane clears, without the hesitation some systems have. The only safety feature which is intrusive is the speed limit warning and unfortunately you have to slough though some menus to mute it.

There are four ISOFIX and five top-tether anchor points spread across the rear rows, which should delight families.

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.

The Discovery 35th Anniversary Edition is covered by a five-year/unlimited-kilometre warranty, which is fairly standard for vehicles in the luxury SUV segment. However, it's worth noting the Nissan Patrol is offered with a 10-year (conditional) warranty.

Land Rover offers a pre-paid, five-year service plan for around $3500, which is cheaper than paying for each service individually. Service intervals are well spaced at every 12 months or 20,400 km, whichever comes first. There are approximately 71 authorised Land Rover centres across Australia, so even if you live regionally, you should be able to service your Discovery fairly easily.
