Lexus IS300H vs Lexus LX500D

What's the difference?

Smooth, cosy, quiet, the IS looks and feels better than ever, but without a doubt this hybrid version is a car best suited to cruising the dense metropolis of Chiba at midnight more than it is carving up a bunch of S-bends in the Australian countryside on the weekend.

While that might still limit its appeal for fans of German sports luxury sedans and place it further from the original IS’s ambitions, it does offer an intriguing efficiency and luxury focused alternative, without the compromises brought by rivals with more sporting intent. In a way then, the IS 300h perhaps inadvertently best embodies what Lexus is as a brand.

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.

Look closely and quite a lot has changed. This is really a story of doing a facelift right. Lexus has kept all the great-looking bits of the car that launched in 2013, like its striking side profile and angular accents, while dumping most of its least popular elements like the spidery front light-clusters and busy front splitter, in favour of something more refined and conservative.

It even adds some new flair in the rear three-quarter, with dramatic LED light-clusters working their way into a trendy highlight strip across the boot lid.

These changes all add up for a much tougher, sportier, and nuanced design compared to the outgoing car. One that manages to make an eight-year old design look as contemporary as ever.

I even liked our test car in its plain black shade, although I'm less sure about those conservative-to-a-fault, almost Camry-esque alloy wheels.

On the inside, sadly not a whole lot has changed. The busy design looked dated when this generation of IS launched in 2013, and it still looks dated now.

The visual assault of buttons, toggles, displays, textures, and trims is a lot to take in, and makes the cabin feel smaller than it is.

It probably didn’t help the sensory overload of this car’s interior as I hopped out of the stripped-back interior in the Tesla Model 3 I had the week before.

My less-than-impressed brother, a student of design, described the IS’s interior best when he told me “It’s a bit maximalist, don’t you think?”

If nothing else, at least Lexus hasn’t blatantly imitated anyone else when it comes to its interior, but the brand remains firm on dorky design items like the laptop touchpad, redundant drive-select dial, and odd vacant panels under the climate unit which do it no favours.

A welcome upgrade for the 2021 model year is the new media screen, a highlight piece perched atop the dash. It’s bright, has excellent contrast, and doesn’t seem to fall victim to glare.

The Apple CarPlay support I used was seamless and sharp and made the most of the available real-estate in its widescreen layout.

I somehow didn’t mind that the instrument cluster in this base car is analog. It almost suits the IS’s character better than a digital set-up would. Also offered is a small information display between the dials which I used for monitoring the hybrid drive.

A final note on the IS’s design. The fit and finish is quality, inside and out. It leaves you with an impression that this is an immaculately built vehicle, one that should be a must for all luxury cars, and always a strong point for Lexus.

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.

Well, the IS is a sedan, so it doesn’t quite have that high-riding appeal of an SUV, and for this update it has even leaned further into its low-slung proportions with a roofline that descends a further 15mm and a boot lid which is 31mm lower overall.

As with the previous car, the interior is quite closed-in thanks to that busy dash design and large centre console. Rather than feeling claustrophobic though, it is best described as cosy, with lots of plush finishes throughout the doors and centre stack befitting a luxury nameplate.

Adjustability is great for the front two occupants and there are two large bottle holders between the seats, a large but shallow console box under the armrest, bottle holders with adjoining bins in the doors, and a smallish glove box.

That’s about where storage ends though, with no extra trays or bins in front of the oddly placed shifter, just an awkwardly finished plastic panel where it feels like a little tray or storage cutaway should be.

The touchpad for operating the media screen joins an unnecessary drive-select cluster in eating up centre console space where there could be more storage.

The rear seat is quite limited on space despite being lavishly trimmed. I fit behind my own (182cm/6'0") driving position with little knee or headroom to spare.

Again, it’s cosy and very comfortable, but if you're taller or wider than me you may run into issues.

The centre rear seat is all but useless for adults, with the IS’s rear-drive architecture necessitating a huge transmission tunnel that almost comes as high as the seat base itself.

Storage is limited to pockets on the back of the front seats, small bins in the doors that double as handholds, and a drop-down armrest with two bottle holders.

There are no power outlets for rear passengers, but there are dual adjustable air vents.

Boot space is 450L which is a little small for the class. It’s impressive the hybrid only managed to lose 30 litres compared to petrol-only IS variants, though, so best to count your blessings.

The largest CarsGuide travel case easily fit in the wide but short available space.

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 updated LX range is available as an LX500d in Luxury, F Sport, Sports Luxury or Overtrail spec, all with a 3.3-litre V6 twin-turbo-diesel engine. Or you can opt for the LX600, which is available in Luxury, F Sport, Sports Luxury, Overtrail or Ultra Luxury spec, all with a 3.5L V6 twin-turbo-petrol engine.

Prices start from $158,700 (diesel, excluding on-road costs) or $162,200 (petrol, excluding on-road costs) for the LX Luxury seven-seater through to $220,950 for the petrol-only LX Ultra Luxury.

Our test vehicle, the 2026 Lexus LX500d Overtrail, the supposed off-road hero of the new four-variant LX500d line-up, has a price-tag of $182,300 (excluding on-road costs).

The standard features onboard this five-seater include a 12.3-inch multimedia touchscreen system (with wireless Apple CarPlay and Android Auto), wireless charging, a centre console cool box and more smart device charge points than you can poke a USB-C stick at (six, in fact).

As mentioned, the Overtrail is aimed at being the line-up’s off-road master and to that end it has front and rear locking differentials, Toyo Tires’ Open Country all-terrains (265/70R18 116H) on 18-inch matt grey alloy wheels, an underslung full-sized spare tyre, as well as a stack of driver-assist aids – including the proven Multi-Terrain Select from Toyota’s LandCruiser 300 Series – all aimed at turning you into an off-roading expert.

Exterior paint choices include Moon Desert (on this test vehicle and available only on the Overtrail), Sonic Quartz, Graphite Black, Titanium, Liquid Metal, and Khaki Metal.

All colour choices are standard/no cost on the LX.

The IS 300h does stand out from the luxury sedan crowd by offering a hybrid drivetrain at a reasonable price. Some rivals offer plug-in options further up the price scale cementing them as a niche option, but the beauty of this Lexus is its very mild $3000 price jump over the base petrol car.

The base car’s 2.0-litre turbo is dumped in favour of a 2.5-litre non-turbo Atkinson-cycle four-cylinder hybrid set-up similar to the one proving popular in the Toyota Camry and RAV4.

The petrol engine produces 133kW/221Nm on its own, and the electric motor produces 105kW/300Nm. Toyota says the “combined system output” of this is 164kW.

Either way, that's less than the base 2.0 turbo. The 300h also swaps out an eight-speed torque converter automatic in favour of a continuously variable transmission. Rare in a rear-wheel drive car.

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.

As you might hope this hybrid IS has an astoundingly low official/combined fuel consumption rating of 5.1L/100km.

I was pleased to find that after a week of mainly urban driving conditions, our IS was returning a figure of 6.9L/100km. Not bad at all, especially for a class where fuel consumption can get a little out of hand with turbocharged engines or V6s.

Of course, using the hybrid system to your advantage over the long term will get this number much lower, as I discovered on my long-term test of the Toyota Corolla hybrid which essentially uses a smaller version of the same system.

Certainly, if fuel consumption is a high concern, you’re better off with this car than the top-spec V6 (IS 350) which will easily see consumption enter double digits.

Lexus recommends a minimum RON rating of 95 for the IS 300h, and the fuel tank is 66 litres regardless of variant, giving the hybrid an impressive theoretical range of around 1000km.

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.

There is no doubt the IS 300h is capable. You can feel it through the car’s solid rear-drive underpinnings, silky smooth steering, and reactive chassis.

What this car doesn’t offer is excitement in quite the same sense as many of its rivals. That’s down to this hybrid’s drivetrain. It just doesn’t have that powerful follow-through in the same way turbocharged BMWs or Audis or Mercedes do.

If it’s that 'sports luxury' experience you’re seeking better off looking to the base 2.0-litre turbo or the V6 and their eight-speed automatics.

The 300h does offer something a bit different. The gentle refined efficiency of Toyota’s signature hybrid system in a luxury rear-drive package that’s smaller than this car’s ES bigger brother.

While it may feel capable thanks to the lighter suspension components and altered track that the brand has committed to for this update, the hybrid drive matches this car’s softer character brought about by its gentle suspension tune and light steering.

This is an easy car to drive around a city, it filters out bumps nicely, while offering near silence in the cabin and breezy steering for every day scenarios like manoeuvring in tight parking lots.

The CVT auto and instantaneous torque available from the electric motor make it best at traffic speeds, being both reactive and predictable, with silent acceleration when inching forward at the lights or cruising along at 50km/h.

As you might expect though, the wheezy Atkinson cycle engine and CVT conspire for a noisy and less than engaging experience under heavy acceleration.

It’s not as though you’re rewarded with particular vigour either, with this combination being a bit sluggish when a lot is asked of it.

It loses its reactivity and refinement at higher speeds or in the corners on country roads as the transmission elastically tries to keep up with the demands of the driver.

Still, few luxury sedans are quite as purpose-built for the toils of a city, and if you want to get drawn into this car’s hybrid drive antics, it’s easy to make a game out of saving fuel by trying to rely on its low-speed electric motor capability.

Really then, it leans into its urban luxury appeal. A luxury sedan for the streets of Tokyo. An ideal car in this class for the urban environment.

If you don’t care for the thrill of a turbocharger or frequently seek to explore the twists of your nearest B-road, you could do worse than the comfort and ambiance the 300h offers.

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.

At time of writing, the 2026 Lexus LX 500d Overtrail does not yet have an ANCAP safety rating.

Standard safety equipment includes 10 airbags (driver and front passenger, front knee and side, rear side and curtain), as well as auto emergency braking (AEB), adaptive cruise control, lane departure alert, lane trace assist and lane keeping system (with emergency driving stop system), road sign assist, safe exit assist, facial recognition, driver monitor camera, and more.

Driver-assist tech aimed at making you a better off-roader than you already are includes downhill assist control, hill start assist, crawl control, Multi-Terrain Monitor (MTM) with panoramic view monitor, active traction control, tyre pressure monitor, active height control and more.

Lexus gets slightly ahead of the luxury pack with an extra year of warranty. While BMW and Audi still sit on three, Lexus offers four, but it is limited to 100,000km and is still outdone by Mercedes-Benz and Korean newcomer, Genesis, offering five-year/unlimited kilometre promises.

The IS has capped price servicing fixed at $495 for the first three years of ownership with roadside assist, and the brand will even pick up and drop off your car, or offer a free loan car during every 12 month or 15,000km service.

It’s worth noting that German rivals offer pre-paid service packages out to five years, and Genesis is trying to make a splash with free servicing.

Lexus does offer a luxury ownership program dubbed ‘Encore’ which includes invites to experiences and certain partnerships with restaurants and the like to keep potential owners enticed.

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.
