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 Kia Sorento S diesel AWD is in the lower spec ranks of the Sorento line-up but it still seems like it would be, on paper at least, an easy vehicle to live with.
It’s a seven-seater with updated technology and a boosted features list and while it may not have the plush appeal of those in the Sorento upper echelon, such as the GT-Line, the Sorento S diesel AWD has plenty of potential as a family mover.
But what’s it really like? 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 Kia Sorento S diesel AWD is a solid buy option in the lower-spec realm of the market. This AWD SUV is not spectacular but it manages to be competitive and, as a seven-seater with updated technology and some good features, it does have ample potential as a daily-driving family mover.
However, if you want more safety tech and more premium accoutrements, you’re likely better off forking out the extra $10,000 or so and getting a top-spec Sorento GT-Line instead.
The Sorento’s exterior is stunningly inoffensive. So, for anyone looking for an SUV that won’t make passers-by dry retch that’s all boxes ticked, I reckon.
The cabin feels family-friendly and functional. It's a basic but well designed space, although there’s no getting past the fact this is at the cheaper end of the Sorento line-up as its cloth seats and expanses of hard plastic remind you.
That said, chrome-like touches and faux hand-stitching go some way towards balancing out that impression.
The low-slung dashboard with integrated 12.3-inch touchscreen dominates the front of the cabin in a good way.
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.
This Sorento is 4815mm long (with a 2815mm wheelbase), 1700mm high and 1900mm wide.
As mentioned earlier, the interior is quite basic and simply designed, but with a low-key classiness about it.
The driver’s seat is six-way manually-adjustable with a pump-action for height, so pin-pointing your preferred position is a welcome minor workout unto itself.
The front seats are adequately comfortable without being too plush – that’s fine with me – and from there driver and passenger have ready access to plenty of storage and cupholders (including two in the front, four in the second row and two in the rear seat) and charging options (including two USB charge points in the front console and one 12V power outlet behind the centre console and one in the cargo area).
My teenagers weren’t impressed at all with the fact they had to plug their smartphones into charge points at the front. Oh, the torture!
The 12.3-inch digital multimedia system has Apple CarPlay and Android Auto, both wired or wireless, and it’s an easy-to-use set-up with a crisp screen.
Air-con is a manual-controls affair, second-row passengers get air vents only (on the rear of the centre console), and third-row passengers don’t get vents or fan controls.
The second row is reasonably comfortable with room enough for head, shoulders and legs to be on the right side of comfy.
It sports a bottle holder in each of the doors, and there’s a centre armrest in the second row with cupholders for the El Grande cups of whatever almond-infused crappuccino your obnoxious screenagers are currently addicted to.
The second row is in a 60/40 configuration, which slides, reclines and folds down flat.
The third row is in a 50/50 configuration, a split-fold flat set-up, and it's the realm of mini humans – or you could put adults back there for any trip lasting longer than 10 minutes and you’ll be hated for life.
For those interested in packing potential space, the rear cargo area offers a listed 179 litres of storage capacity; a listed 608 litres in the rear cargo area when the third row is folded away; and 1996 litres when the second and third rows are packed away.
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'.
My test vehicle this time is the Kia Sorento S diesel AWD, which sits at the bottom of the four-variant Sorento line-up (S, Sport, Sport+ and GT-Line). There is a petrol version, but the Kia Sorento S diesel AWD has a price of $53,680 plus on-road costs.
Standard features include a 12.3-inch digital multimedia touchscreen (with wired/wireless Apple CarPlay and Android Auto), a basic digital driver cluster with 4.0-inch multi-function LCD display, AEB, blind spot collision avoidance assist, rear cross-traffic collision avoidance assist, 17-inch alloys (plus a full-sized spare), LED headlights, daytime running lights and fog lights.
It has cloth seats, six-way manually-adjustable driver’s seat, manual air-conditioning, second-row passengers get air vents only (on the rear of the centre console), and third-row passengers don’t get vents or fan controls.
Exterior paint choices include 'Clear White', as well as premium paint choices (all at an additional cost) such as 'Silky Silver' (on our test vehicle), 'Steel Grey', 'Mineral Blue', 'Gravity Blue', 'Aurora Black', 'Snow White Pearl', 'Volcanic Sand Brown' and 'Cityscape Green'.
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.
This Sorento has a 2.2-litre, four-cylinder common-rail diesel engine, producing 148kW at 3800rpm and 440Nm at 1750-2750rpm and that’s matched to an eight-speed dual-clutch auto transmission.
This is a generally clever and effective combination, but there is noticeable lag to acceleration from a standing start, no matter how hard you stomp the right foot.
It has all-wheel drive (part-time with lock mode) and driving modes that include on- and off-road options.
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 for the 2.8-litre four-cylinder Sorento S diesel is 6.0L/100km on a combined cycle.
Actual fuel consumption on this test, from pump to pump, was 6.6L/100km.
This Sorento has a 67-litre fuel tank so – going by that fuel consumption figure – you should be able to get a driving range of about 1015km from a full tank.
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.
As I mentioned earlier, this SUV can feel a tad lardy at times, especially from take-off, but it exhibits slightly livelier characteristics soon enough. Just don’t climb into the driver’s seat expecting a dynamic experience.
Steering has a nice balance to it and the Sorento never feels gargantuan so navigating through busy city and suburban streets is on the correct side of easy.
Ride is a bit firm, but the all-pervasive mindful peace you experience from being in such a hushed cabin tends to mostly negate any minor discomfort you may otherwise feel from clipping every lump and bump on the road.
On-road driving modes are 'Comfort', 'Sport', 'Eco' and 'Smart' and off-road modes are 'Sand', 'Mud' and 'Snow'. All of these adjust engine outputs, throttle control and transmission behaviour to best suit the terrain and driving conditions.
Niggle: The driver-assist tech is a bit abrupt and intrusive. I’ve found this to be the case in Hyundai SUVs, too.
The traffic sign recognition, in particular, is clunky, reacting to signs that don't apply at that time of day, for example school signs, or it reacts to signs that don't actually apply to that section of road. So it's regularly chopping and changing between what speeds you should be at and what speeds you shouldn't.
This Sorento is an AWD with 176mm of ground clearance so I tested it on muddy grass, firm sand and gravel tracks. Nothing outrageous, but mildly challenging enough to make sure the all-wheel drive system can do what’s expected. And it does, seamlessly.
These off-road drive modes are, of course, no substitute for 4WD, but they are fine for when conditions become a little bit slippery. For example, if there’s been a drizzle of rain on the bitumen or the dirt track becomes a bit muddy.
This Sorento has a maximum towing capacity of 750kg (unbraked trailer) and 2000kg (braked).
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.
The Kia Sorento has the maximum five-star ANCAP safety rating from testing in 2020.
Standard safety gear include seven airbags*, AEB (with car, pedestrian, cyclist and junction turning assist, from 5.0km/h to 85km/h; car detection up to 75km/h), as well as forward collision warning, blind-spot monitoring, rear cross-traffic alert, lane departure alert, front/reverse parking sensors and more.
*Note: the curtain airbags only cover the first and second rows.
Because this is the entry-level Sorento it misses out on such handy tech as the side parking sensors, 360-degree around-view monitor and blind spot view monitor that are found in higher spec variants.
The Sorento has five top-tether child restraint anchorage points and four ISOFIX child seat mounts (two in the second row and two in the third row).
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.
A seven-year/unlimited km warranty applies to the Sorento line-up.
Servicing intervals are scheduled for every 12 months or 15,000km, whichever occurs soonest.
Capped-price servicing covers seven-years/105,000km and at the time of writing ranges between a low of $370 and a high of $817 per service over that period. Total cost is $3787 for an annual average of $541, which isn't particularly cheap.
