What's the difference?
Jeep Australia's first plug-in hybrid, the Grand Cherokee 4xe, has arrived at a time when the company’s sales figures need a decent shot in the arm.
Though it’s seemingly spearheading a large and extra-large SUV hybrid push into the Aussie market, with the likes of a Toyota LandCruiser 300 Series hybrid on its way, the marque’s debut PHEV is only available here in the range-topping Summit Reserve spec, and only as a five-seater.
So, does the 4xe have enough of a jump on any large SUV hybrid rivals – including a rumoured but postponed Ford Everest hybrid – and is it enough to give the brand a much-needed boost?
Read on.
The Lexus LX range has undergone significant updates across the board and the carmaker has also introduced an off-road-focused variant, the Overtrail, to the Aussie market.
The LX500d Overtrail is geared up for 4WDing and, as such, is kitted out with front and rear locking differentials, Toyo Open Country all-terrain tyres on 18-inch rims, as well as a stack of driver-assist aids – including the proven Multi-Terrain Select from Toyota’s LandCruiser 300 Series – all aimed at making you The Absolute King of the Dirty Weekend.
But, being a Lexus, the Overtrail is of course on the right side of premium, replete with a features list as long as … something that is long.
So, how does it perform off-road?
Read on.
A wise man* once said "Being first can sometimes feel like being wrong" and perhaps that's how it is with the 4xe, but at least Jeep Australia is giving the large SUV hybrid realm a good ol' try.

The company's first plug-in hybrid, the Grand Cherokee 4xe, is not perfect by anyone's standards, however, it is a definite move in the right direction.
It's a quiet and refined drive, it retains the brand's renowned 4WD capability, and even its hefty price-tag likely won't dissuade Jeep loyalists from giving it a go.
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.
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.
The Jeep Grand Cherokee Summit Reserve 4xe PHEV retains the regular model’s level of functionality but adds a reasonably classy touch to everything.
All seats offer adequate comfort, support and room.
There are plenty of storage spaces, cupholders etc, and charging points - two USB-A and two USB-C plus a 12V socket in the front and two USB-A and two USB-C plus a 230V point in the back.
Controls are generally easy enough to locate and operate although some buttons are positioned in awkward places – including drive-mode buttons under the steering wheel – and it sometimes takes a few finger-stabs at the multimedia touchscreen to get to where you want to go in the operating system.
In terms of packability, the rear cargo area has a listed 1067 litres of space, and, with the second row folded and out of the way, that space opens up to 2004 litres.
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 five-seat Jeep Grand Cherokee Summit Reserve 4xe PHEV has a MSRP of $129,950 (excluding on-road costs).
Standard features include a 10.1-inch multimedia system (with Apple CarPlay and Android Auto), a 10.25-inch digital instrument cluster, 19-speaker audio system, quilted Palermo leather-trimmed seats, air suspension and 21-inch alloy wheels.
It also has a heated steering wheel, 12-way power-adjustable seats and four-way power lumbar adjustment with memory for driver and front passenger, driver and front passenger seat massage function and heated and ventilated seats (driver, front passenger and rear outboard passengers).
A Mode 2 charging cable is also included.
An 'Advanced Technology Group' pack is available as a $5500 option and that includes a head-up display, a 10.25-inch screen for the front passenger, wireless phone charger, and night vision camera.
Exterior paint options include 'Bright White', 'Diamond Black', 'Silver Zynith', 'Velvet Red', 'Baltic Grey', 'Rocky Mountain', 'Midnight Sky' and 'Hydro Blue'.
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 Jeep Grand Cherokee Summit Reserve 4xe PHEV has a 2.0-litre four-cylinder turbo-charged petrol engine, two electric motors (one on each axle) and a 17.3kWh battery.
Combined engine and electric outputs for power and torque are 280kW and 637Nm, respectively. The 4xe has it over any of its stablemates equipped with the 3.6-litre Pentastar V6 petrol engine because that yields 210kW and 344Nm.
The 4xe has an eight-speed automatic torque-converter transmission and regenerative braking.
Drive modes include 'Hybrid' (with combined engine and electric motor providing “maximum instant torque and impressive acceleration”, according to Jeep), 'Electric' (“zero emissions”) and 'eSave' (aims to save battery power).
There are a few options available when it comes time to charge the 4xe.
The 4xe vehicle has a Mode 2 charging cable so you can charge it at home in less than 10 hours, according to Jeep.
With a full charge, the 4xe has a claimed driving range, on electric charge alone, of 52km.
Jeep reckons a Mode 3 (wall box) single-phase electric vehicle charger will fully charge the 4xe in less than three hours.
If out and about and looking for a charge, a 4xe driver can use the onboard 'UConnect' system to locate an appropriate public charging station.
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 mentioned, the 4xe has a listed electric-only driving range of 52km.
On our official test day, we drove just under 50km on a full electric charge and then the rest of the trip was courtesy of the good ol’ petrol engine.
Jeep's official figure for the combined cycle is just 3.2L/100km, but that's predicated on keeping the hybrid battery charged at all times. On fuel-only we recorded 11.6L/100km.
The 4xe has a 72-litre fuel tank (you need 95RON premium to fill it), so going by that on-test fuel-consumption figure, you could reasonably expect to get a driving range of about 620km out of a full tank.
Add an approximate electric range of about 50km on a full charge to that figure and you have a total estimated driving range of 670km.
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.
We’re all time-poor, right? So, why should I take up your time and rattle on about the 4xe for a thousand words when I can get the essence of it across to you, the reader, in a few sentences? Call me, Mr Thoughtful.
This is generally a big, quiet and refined, easy-steering large SUV, but it feels bulky at times and tends to be quite fussy on irregular surfaces, exhibiting a jittery ride on even brief sections of light corrugations on dirt tracks.
The 4xe’s PHEV set-up is smooth and highly responsive on-road and you can switch between the aforementioned drive modes to suit the circumstance.
Driving range on electric only is listed as 52km. I only recorded a total distance of just under 50km, and it’s a very quiet and smooth drive while relying on electric power.
It regenerates power rather quickly down big hills and via braking, but we’d exhausted all electric charge by the time we’d reached our 4WD test track.
As expected, this Grand Cherokee tackled every off-road challenge without any strife.
The air suspension, set to full off-road height, is a bonus.
Our 4WD test track consists of difficult set-pieces, including one small steep rocky hill that I’ve seen heavily modified vehicles struggle to conquer and, to the Jeep’s credit, it climbed the incline, no sweat.
The 4xe’s efforts were only ever hampered by its 'all-season' Continental CrossContact tyres (275/45R21) which are much better suited to blacktop driving and the fact the 4xe costs upwards of $129,950 and I didn’t want to risk any damage to it.
The 4xe has a listed wading depth of 610mm but our test track was dry so I never had the chance to do any water crossings.
The Grand Cherokee has a solid enough rep as a towing vehicle but, take note, the 4xe is rated to tow 2722kg.
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.
The Jeep Grand Cherokee Summit Reserve 4xe PHEV has the maximum five-star ANCAP safety rating from assessment this year.
Safety gear includes AEB with pedestrian detection, blind-spot monitoring with rear cross-traffic alert, adaptive cruise control, lane-keep assist, driver monitoring, traffic sign recognition, intersection collision assist, and a surround-view parking camera.
The Summit Reserve spec brings with it 'ParkSense' parallel and perpendicular park assist and (low-level autonomous) 'Active Driving Assist'.
It has eight airbags including front, side, and knee (for driver and front passenger), sides (for second-row passengers) and full curtain airbags.
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.
The Jeep Grand Cherokee Summit Reserve 4xe PHEV has a five-year/100,000km warranty and a lifetime roadside assist service.
Servicing is set at 12-month/12,000km intervals and capped price servicing keeps what you pay for each appointment at $399 for the first five.
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.
