Lexus LX500D vs Lexus LX600

What's the difference?

The Lexus LX550d Overtrail holds plenty of appeal for those who’d like to bookend a work week of refined daily driving with a weekend of fun and adventure undertaken in style.

With a full complement of standard features, as well as offering premium comfort and understated design, the Overtrail makes a lot of sense as a potential purchase.

It’s luxurious on the road, capable off-road and the Overtrail holds up quite well if cross-shopped against the likes of Land Rover Defender, Toyota LandCruiser 300 or Nissan Patrol.

There's absolutely no doubting the new LX's off-road credentials, nor the fact that it takes luxury SUVs to new heights in the four-seat Ultra Luxury model. Do you need a massaging chair and a foot-stool to get to your camping site? Probably not, but globally, there's a distinct market for that sort of decadence.

Closer to the other end of the LX line-up, however, there's a fair bit of cross-over in price and luxury terms with the Lexus' close cousin, the Toyota LandCruiser 300 Series. That suggests there might be a LandCruiser that will do the same job for a little less money and, if that's the case, then the LX loses a little relevance, particularly the petrol-engined version here in Australia. Until, that is, you take into account buyers for whom the Lexus badge infers the bank-vault solidity and prestige that the brand has worked so hard to establish. Which is another way of saying; it all comes down to where you stand on the politics of envy.

Note: CarsGuide attended this event as a guest of the manufacturer, with travel, accommodation and meals provided.

The LX500d Overtrail is 5100mm long (with a 2850mm wheelbase), 1990mm wide, and 1895mm high. It has a listed kerb weight of 2690kg.

It has an almost straight-up-and-down, old-school appearance, and leans more towards the retro-cool end of the design spectrum rather than the sleek end – and that styling, which is THE Overtrail look based on the GX Overtrail, works.

Adding to this 4WD wagon’s overall large-and-in-charge presence are its big front grille, bulging wing mirrors, side steps and those all-terrain tyres.

The Overtrail has black exterior touches (door handles and mirrors, window mouldings, wheel-arch trims), black front and rear bumpers, and bridge-type roof rails that top off its rugged look and further set it apart from its LX stablemates.

There are a lot more identifiably-Lexus, premium-style touches going on inside the Overtrail, including Overtrail-specific premium leather-accented front seats with Monolith colour stitching, Ash Sumi Black ornamentation, a plethora of soft-touch surfaces and a helpful does of durable plastic.

Perhaps the most left-field design element is the way the LX can, depending on trim level, be configured in terms of its seating. In the past, we’ve seen plenty of SUVs available with a choice of five- or seven-seat layouts, but the LX is the first time we’ve seen seating choices range from seven- to five- to four-seat layouts. If nothing else, it illustrates the breadth of applications a modern luxury SUV is expected to cover.

Those who use their four-wheel drive SUVs off-road will also note the shift back to six-stud wheel hubs. Toyota’s (and Lexus’) move to five-stud wheels a few years ago suddenly made the vehicle’s wheels incompatible with owner’s existing caravans and trailers.

The new LX has also become a committed subscriber to the engine-downsizing theory of modern vehicle design. While the previous model was available with a 4.5-litre turbo-diesel and a massive 5.7-litre petrol, the new engine capacities of 3.3 litres for the diesel and 3.5 litres for the petrol represent major philosophy changes. Both the new engines are now V6s, rather than the previous V8 layouts.

And to give the new car a James Bond moment, all models bar the entry-level version feature a fingerprint sensor to control the starter button function. Q would be pleased.

Overall, the interior is functional, the build quality is impressive and this is a Lexus so, of course, there are lashings of prestige.

For starters, the seats are comfortable. The 2026 Lexus LX500d Overtrail has a 10-way power-adjustable driver’s seat, and an eight-way power-adjustable front passenger seat and both have four-way Lumbar power adjustment and massager.

The second-row seats in this five-seater are in a 60:40 split folding configuration and are also on the right side of comfortable, which is not always necessarily the case in a 4WD wagon.

The 12.3-inch multimedia touchscreen system dominates the upfront layout and shows navigation, your smartphone desktop, reversing camera view, etc and when off-roading it displays multi-terrain monitor showing the road surface and other conditions.

Underneath that main screen is a 7.0-inch touch display that displays drive modes, adaptive variable suspension, air-conditioning controls and the like.

Both are easy enough to use without hassle.

The driver also gets a head-up display, projected onto the windscreen right in front of the driver, but say hoo-roo to that info once you’ve donned polarised sunnies.

The Overtrail has a powered sunroof/moon roof, whatever you want to call it.

It has plenty of charge points – including two USB-Cs upfront and two for the second-row passengers, and a wireless phone charging pad in front of the cooled centre console – and there are 12-volt outlets front and rear, and a 220V outlet in the rear cargo area.

There are numerous cupholders – upfront and in the second-row armrest – and bottle holders in the doors.

The five-seater Overtrail’s rear cargo area has a 220V/100W socket (to run camp lights, fridge etc), a cargo blind, tie-down points and cup holders on both sides, left over from the seven-seat layout.

Rear cargo space is listed as 1109L with all seats in use, and cargo space is 1960 litres if the second row is folded down.

The rear tailgate is powered and lifts to open rather than swings to the side as the barndoor-style doors do.

Minor gripe: You’d think with the amount of cash you spend on an Overtrail that Lexus would equip the off-road-focused LX with rubber floor mats because its interior should be ready to cop more than its fair share of dirt, sand and mud during its driving days.

The practicality of each variant of the new LX is dependent entirely on how many people you need to move. The base-model version has seven seats with a two-three-two layout, while the Sport Luxury and F Sport feature five conventional seats in two rows.

The Ultra Luxury’s four individual seats obviously make it the variant of choice for the buyer who doesn’t need the extra seats, but clearly limit its appeal for families. But if luxury is your aim, the rear passenger seat in particular is the one to be in as it can be configured to offer up to a metre of legroom and even features a footrest when the front passenger’s seat is moved all the way forward. Both rear seats are also heated and cooled and reclinable to an angle that NASA has calculated offers the maximum support for the human body.

Vents in the rear seat area allow for an air-shower (of cool air over the passengers) or an air-curtain (a blanket of warm air at shoulder height).

The seven-seat versions have a third row of seats that folds flat into the floor (a major improvement over the old fold-up third row) and the second row folds and tumbles into the footwell. There’s a 220-volt outlet in the luggage compartment, too.

Cargo space is slightly less than the old model, but with second and third row seats folded, the LX has cargo space of up to 1871L.

The single-piece tailgate of the new Lexus won’t win as many friends as the old, split tailgate design which formed an impromptu kitchen bench or covered picnic seat. But the single rubber seal of the new design may be an advantage in keeping dust out on outback roads.

Much has been made of the Toyota LandCruiser’s $90K starting price in LC300 form, so it will come as no surprise to learn the new LX is likewise bold when it comes to the sticker on the windscreen.

The range kicks off in seven-seat form with the entry level LX600 (petrol) and LX500d (diesel) priced at $152,300 and $148,800 respectively. Of course, at these price points, entry-level is a relative term, and the list of standard features is a long one, indeed.

Lexus has gone for a tech-heavy look and feel here, with a 12.3-inch main display, a 7.0-inch lower screen as well as 8.0-inch multi-function display screen and even a colour head-up display for the driver. Lexus’ latest generation multi-media system is used, but may require some familiarisation for some owners.

The entry-level car also gets 20-inch alloy wheels, heated and powered front seats, leather-accented upholstery, a premium 25-speaker stereo system, LED headlights and active height control of the suspension via hydraulically-adjustable dampers.

Lexus has also fitted 'Multi-Terrain Select' and 'Multi-Terrain Monitor 2' to allow for different types of terrain and grip conditions as well as giving the driver a 360-dgeree camera’s-eye view of the track and the vehicle crossing it.

If that’s not enough, Lexus also offers what it calls an 'Enhancement Pack' which adds 22-inch alloy wheels, a sunroof and a kick-sensor tailgate for an extra $5500.

The next step up the LX ladder is the Sports Luxury model with a price-tag of $165,800.

For the extra money, you get a premium leather covering for the seats, and the front seats become heated and ventilated. There’s also a heated steering wheel, a cool box (much appreciated in Australia) a split rear-seat entertainment system and specific trim including timber veneer.

The new F Sport is next and adds not just more equipment but more capacity to the car’s off-road aspirations. That’s down to a Torsen rear differential which is torque-sensing in the way it distributes drive to each rear tyre, as well as performance dampers at each corner.

Dark exterior accents and a mesh grille help justify the F sport’s sticker of $171,800, as do interior touches such as seats with extra bolstering and some aluminium trim accents.

Which brings us to the headline act, the Ultra Luxury, which represents a huge price jump to $210,800. As well as extra equipment such as a rear touchscreen for climate control, wireless device charging, the Ultra Luxury is designed as a vehicle where the owner is more likely to be in the rear seat rather than the driver’s seat.

A strict four-seater, the vehicle has a pair of plush rear bucket seats (Lexus calls them captain’s chairs) which recline a full 48 degrees and feature a massage function. The passenger’s rear seat even runs to an ottoman and the entire cabin is trimmed in plush, quilted leather. Surely, with this layout, Lexus has achieved peak oligarch.

Our test vehicle has a 3.3-litre turbo-diesel engine – producing 227kW at 4000rpm and 700Nm at 1600-2600rpm – a 10-speed automatic transmission and a full-time 4WD system.

This is a big wagon so it takes some encouragement to get going off the mark – it is sluggish rather than zippy around town – but once underway on an open road, especially on a highway, it punts along nicely.

I drove the seven-seater Lexus LX600 Sports Luxury – with a 3.5-litre petrol engine (305kW and 650Nm) – immediately after this test and – with the same dimensions, but 10kg lighter than the Overtrail – it’s more punchy off the mark.

The Lexus LX500d Overtrail has a variety of drive modes including Custom, Comfort, Eco, Normal and Sport S and Sport S+ for on-road driving.

It has front and rear locking diffs, and Multi-Terrain Select (MTS) drive modes for off-roading. Those modes include Auto, Sand, Mud and Rock. Each off-road driving mode adjusts throttle response, transmission shift patterns, wheel-slip control, engine power delivery and braking to best suit the specified terrain.

While the Toyota LandCruiser 300 Series is a diesel-only proposition, the Lexus LX takes a broader view of what its buyers will want in such a vehicle.

As a result, there’s a choice of petrol or diesel power for the LX range, with both engines covering all variants apart from one. To add weight to the theory that the Ultra Luxury model is for people for whom fuel costs really don’t matter, it’s available only as a petrol vehicle.

The turbo-diesel engine is the 3.3-litre V6 twin-turbo unit we see in the 300 Series. It’s unusual in that it uses hot-side-in technology where the exhaust system and turbochargers live inside the vee of the engine, rather than hanging off each side as is much more common. Lexus claims greater efficiency from this layout with less plumbing between the cylinder head and turbo units as well as a more compact design.

Outputs for the turbo-diesel are 227kW of power, with an impressive 700Nm of torque produced anywhere between 1600 and 2600rpm, which is where the engine will spend most of its operating life.

The petrol engine is also a V6 and also twin-turbocharged. It measures 3.5 litres and, again, features a design that allows a smaller capacity engine to exceed the outputs of the physically larger, previous model. To that extent, it makes 305kW of power and 650Nm of torque; both impressive figures.

There’s only one transmission available on the LX, and that’s a 10-speed conventional automatic. To compliment that rugged, ladder-chassis design, the LX also has a transfer-case with proper off-road gear ratios. This is what gives the vehicle its rock-crawling and river-crossing abilities, while permanent four-wheel drive and the Multi-Terrain Select system mean no-fuss operation.

Official fuel consumption is listed as 8.9L/100km (on a combined cycle), but on this test, I recorded 12.8L/100km.

The Overtrail has 110L fuel capacity (80L main tank, 30L sub tank) so, going by my on-test fuel-consumption figure, you could reasonably expect a driving range of about 860km from a full tank.

However, as with any vehicle, once you’ve loaded it with real-world burdens (e.g kids, dogs, camping gear etc) you’ll soon see fuel-use figures increase.

Much has been made of the new LandCruiser’s fuel-tank reduction to its new total of 110 litres. The LX follows suit with an 80-litre main tank and 30-litre auxiliary tank, but it’s worth remembering the improved efficiency of the new drivelines will maintain the range to a useful total. The base-model diesel version also misses out of the second tank for an 80-litre total.

Toyota claims a combined figure of 8.9 litres per 100km for the diesel and 12.1 litres for the petrol. On the open road, both variants will get pretty close to those targets (even though they’re a combined urban-highway figure) so the touring range remains useful and better than 1000km for the turbo-diesel with the twin tanks.

On-road, the Overtrail is impressive: refined, comfortable, unstressed and it offers up controlled ride and handling.

The Overtrail sits nicely on sealed road surfaces – it has a wide wheel track and long wheelbase – and it maintains that composed posture even on gravel or dirt tracks.

It does exhibit some body-roll when pitched through country bends but in a large 4WD wagon that characteristic is no real surprise.

Ride quality is impressive and the suspension set-up, including the Overtrail’s adaptive variable suspension which adjusts damping force according to the drive mode selected, manages to smooth out the worst of most surface irregularities. Active height control is worth mentioned here because it's designed to optimise the spring rate to keep this wagon stable during turning, acceleration, and braking.

The 3.3-litre turbo-diesel engine and 10-speed auto are a smooth combination producing plenty of power and torque across a broad rev range.

It's mostly quiet in the cabin though wind noise does emanate from the chunky wing mirrors.

One thing I’m not a big fan of is the digital rear-view mirror. I understand the reasoning behind it as it helps establish visibility where you may not have it – for example, if something you’ve packed in the rear blocks your vision, or a second-row passenger’s massive head blocks your vision – but the slightly distorted view depicted on the mirror isn’t altogether helpful and tends to push me into headache territory on longer drives. That’s my story and I’m sticking to it. Maybe my old eyes need testing?

So, how does the Overtrail perform off-road?

Well, you’d expect it to go pretty well, especially as it is equipped with front and rear locking diffs, and a raft of off-road drive modes.

And it does. Mostly.

Steering is nicely balanced and the driver is afforded so much visibility of the track ahead that, even with a massive bonnet in front of you, it’s easy to get your wheel placement spot-on. The Overtrail also has a 360-degree camera system, so that maximises your chances of putting the vehicle on exactly the correct line.

Courtesy of its off-road modes, diff locks etc, the Overtrail drives with impressive composure through most off-road situations, whether that’s along corrugated dirt tracks, up steep rocky hills or through shin-deep mudholes.

It offers a reasonable amount of wheel travel for a large wagon and it has decent all-terrain tyres – Toyo Open Country (265/70R18) – and they provide plenty of grip on a variety of surfaces: sand, loose gravel, shale, even rain-soaked mud which can be very slippery and can quickly fill up tyre tread.

The LX500d Overtrail has 205mm ground clearance which 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 machine. However, worth mentioning again here is the addition onboard of active height control, which automatically adjusts vehicle height – Normal, High 1, High 2, and Low (for easy ingress and egress) – to match the drive mode you select and the driving conditions at any time.

And while the off-road angles – approach (23 degrees), departure (22) and rampover (22.7) – aren’t fantastic, those measurements are industry standard for a larger and upper large SUV, but again, in a vehicle billed as an adventure machine, those angles could be a lot better. In the Overtrail’s favour the underbody is well protected by substantial bash-plates and the Overtrail’s full-size spare is mounted to the underbody.

Wading depth is an estimated 700mm, which is also in the vicinity of standard for an unmodified 4WD wagon.

The side steps protrude and if you fail to drive with consideration then they'll probably cop a scrape and maybe even a bit of a dent.

Towing capacities are 750kg (unbraked) and 3500kg (braked). Payload is 590kg, 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. 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 2690kg, gross vehicle mass (GVM) is 3280kg, and gross combined mass (GCM) is 6780kg.

Lexus surprised us a bit with its choice of test roads for the LX’s launch. As well as some twisty bitumen which might not, on the surface, have seemed the most LX-friendly terrain, the launch also threw in some steep if not otherwise too taxing off-road work.

The steep downhill section highlighted the fact that the LX has probably the best hill-descent control we’ve sampled. Not only is it simple to use with speed variation via the rotary knob that otherwise controls the drive modes, it’s also consistent and doesn’t stumble or lock-up wheels and bang brake calipers intermittently.

The second surprise was how well 2.6 tonnes of luxury off-road SUV handled the winding blacktop. It’s no performance-oriented SUV with its live rear axle and off-road-worthy suspension settings, but it can be hustled along in a pretty tidy manner if you concentrate and keep it flowing.

Beyond that, it was pretty civilised at everything else, too, and although it’s not a compact vehicle by any means, the cameras and sensors ensure that it’s not too much of a brain-teaser to park.

The LX seems to have slightly better noise suppression than the LandCruiser on which it’s based and the diesel version doesn’t seem quite as vocal under load. That said, it’s still very quiet and when rolling along at highway speeds and low engine revs, even the diesel is tomb-like in its silence.

But the petrol is next-level refined. There’s a small degree of engine raspiness when you rev the petrol V6 hard (and you won’t mistake it for a V8) but it’s a sophisticated soundtrack and, at a steady throttle, the petrol LX is even more silent.

The two engines have vastly different torque curves, but the 10-speed transmission is so on top of things that it can tailor its shift-pattern to make the absolute most of whatever torque and power are being produced. You can just feel the transmission holding a gear a little longer when the driver dials up max thrust, but in the interests of getting a heavy vehicle moving swiftly, using a clever transmission is the smart, modern way to do it.

Steering is a fraction light to be completely tactile, but that’s a function of the off-road abilities, and we’re pleased to report that the turning circle is very good given the exterior dimensions and makes tight city work much easier.

The shift paddles are, ironically, likely to be of most benefit when off-road and it’s here that the LX lays the SUV pretenders to waste. With low-ratio gears in the transfer case and that clever 10-speed, the LX will climb up some amazing places. It’s fair to say that, like all good off-roaders, you’ll run out of brave pills before the LX runs out of talent.

And while the suspension does a good job off-road, the live rear-axle and independent front suspension also combine pretty well on the blacktop. There’s some initial thump on pattery bumps that are felt more than heard. But as the bumps get bigger, the LX gets even better at dispatching them.

The variable ride height feels like air-suspension but is actually a clever hydraulic adjustment to the dampers to increase their length and, therefore jack the vehicle up for off-roading. Strangely, the ride seems to become a fraction firmer (and we mean a fraction) as the height cranks up, but most owners will never notice it.

What they will notice is the composure that the LX has in most settings. No, it’s not the fastest or tidiest handling SUV out there, but it’s well beyond good enough. And off-road? Very, very little is likely to touch it.

Lexus’ latest safety innovations have made it on to the new LX, and as well as the now-usual driver aids and passive safety gear, there are fitments such as an autonomous braking system that can identify cyclists in daylight hours and pedestrians any time of the day or night.

There’s also intersection turn-assist which minimizes the chances of a crash when turning across oncoming traffic, as well as emergency steering-assist to help with fast inputs in a crash-avoidance situation.

The adaptive cruise-control now also features curve-speed reduction if the car thinks a corner is being tackled at too high a velocity. Along with that is road-sign recognition, blind-spot monitoring, tyre-pressure monitoring, 10 airbags (12 in the Ultra Luxury) and Multi-Terrain Monitoring which allows for a transparent on-screen outline of the car, allowing the driver to see what’s around and even underneath the vehicle.

The 2026 Lexus LX500d Overtrail is covered by a five year/unlimited km warranty.

Capped-price servicing applies for five years/100,000km for a maximum of 10 services.

Servicing is scheduled for every six months or 10,000km, whichever occurs soonest and cost per service, at time of writing, is $595.

Lexus Australia recently upgraded its factory warranty to five years/unlimited kilometres (up from three years). That’s better, but by no means a real advantage over most of its competition.

Capped price servicing is available at $595 per service for the first three years. The catch there is that servicing is every six months or 10,000km, an area in which Lexus trails its main competitors.
