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 Audi SQ8 has had a mid-life refresh but this upper large SUV still offers luxury with its powerful V8 engine that fans know and love, as well as the features you would expect in a top model.
It competes against the Mercedes-AMG GLE and Porsche Cayenne but we’re family testing the SQ8 to see how it handles domestic life.
Keep reading to see what we’ve discovered.
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 Audi SQ8 isn’t your typical performance SUV. It’s more refined and less flashy. The tech can be more complicated than it needs to be and if you’re wanting that V8 soundscape, you won’t find it here.
However, the handling and on road experience are superb plus you can comfortably haul the family around and look good doing it.
The SQ8 is a gorgeous coupe-style SUV that looks purposeful and poised with its balanced proportions and wide stance. It’s stands apart from its siblings thanks to the S-styled nose treatment and our test model's black accent package makes the honeycomb grille look even sportier.
The update sees new air intake vents at the front, matrix LED headlights and new chrome exhaust tailpipes.
The upgraded 23-inch alloys with red calipers behind them hint at what’s under the bonnet, as does the Sakhir (sack-heer) Gold paintwork which is aptly named after the one-off Grand Prix race circuit.
The interior looks luxuriously appointed with the black Valcona leather upholstery and the dash is headlined by three high-end technology screens. The SQ8 also gets sport seats featuring a quilted design and 'S' badging but there’s not much else separating it from its siblings.
Audi fans will love the the SQ8's more understated interior but newcomers might be surprised it's not as flashy as some of its rivals.
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.
The upper large SUV tag certainly makes sense when it comes to cabin space because there's a lot of it. Both rows enjoy ample head- and legroom and access is great thanks to wide door apertures and high ground clearance.
Comfort is high with well-padded seats and thanks to the Sensory Package all but the middle back seater get some luxury extras.
The centre rear position has compromised legroom courtesy of the transmission tunnel, so it's best for a kid. However, the front seats take the cake with their massage, heat and cooling functions and adjustable supports.
Amenities are great throughout the car and the extendable sun visors, rear electric sunshades, soft-close doors and four-zone climate control clinch the practicality deal.
Individual storage is a bit sparse up front with two cupholders, a drink bottle holder in each door and a shallow middle console that realistically only fits a phone.
The glove box is a great size. I can fit my handbag in it, but there are not a lot of areas to pop your smaller items in.
Individual storage is a bit better in the rear as you get two big map pockets, a drink bottle holder in each door, plus two cupholders in the fold-down armrest - so it feels like you have more places for your bits and pieces.
Technology looks amazing but overwhelming to use until you wrap your head around it all. The haptic feedback also gets tired fast. The built-in satellite navigation is super simple while the head-up display and digital instrument cluster feature pull through directions, which is handy.
Charging options are good with each row getting two USB-C ports and a 12-volt socket but the front also enjoys a wireless charging pad. The pad is slow to charge, though, and left my iPhone feeling super hot whenever it was used.
The boot is a good size at 605L and easy to access, too. The sloping roof means larger items have to sit flush with the seats but you shouldn’t have to worry for road trips.
The back seat has a 40/20/40 split which opens up storage options and this model has a powered tailgate.
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'.
There are three fuel-based variants for the Q8 and the model on test is the top-spec SQ8 TFSI quattro. Its mid-life refresh has seen a price hike of $10,015, bringing it's before on-road costs price to $178,815.
Our test vehicle has also been fitted with a few extras, like a 'Sensory Package' ($14,400) which includes a black headliner, upgraded 23-speaker Bang & Olufsen 3D surround sound system, massage function for the front seats, heat function for the rear outboard seats, electric sunshades for the rear row and an air-quality perfume function.
Also fitted are various black and matt carbon accents across/inside the body for a total of $5400, optioned 23-inch alloy wheels ($3000) and specialised 'Sakhir Gold Metallic' paintwork for $1600. Which brings the total MSRP price tag to $203,215.
Even with all of these extras, the SQ8 is still the most affordable performance SUV compared to its nearest rivals as the Porsche Cayenne GTS starts from $212,600 MSRP and the Mercedes-AMG GLE 63 outstrips them both at $272,300 MSRP.
As you'd expect the standard features list is robust for the SQ8 and includes premium features like a panoramic sunroof, electric front seats with heating/cooling and memory functions, full-leather upholstery, soft-close doors and a heated steering wheel.
There is a bunch of high-end technology throughout which includes a colour head-up display, 10.1-inch touchscreen multimedia system, 8.6-inch climate control panel, 12.3-inch digital instrument cluster, satellite navigation, wired/wireless Apple CarPlay and Android Auto, digital radio, four USB-C ports, three 12-volt sockets and a wireless charging pad.
Practical features include keyless entry and start, rain-sensing windscreen wipers, dusk-sensing LED headlights, a powered tailgate, adaptive air-suspension and four-zone climate control.
Overall, not a bad list of features for this part of the market and you won't be left wanting.
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 4.0-litre, twin-turbo petrol V8 engine that produces 373kW and 770Nm. That means it sits in the middle of its rivals in terms of outputs with the Mercedes being top-dog with its 450kW/850Nm combo.
Still... the SQ8 is no dainty flower when it comes to power delivery and has an impressive 0-100km/h sprint time of just 4.1 seconds.
The SQ8 is a full-time all-wheel drive with an eight-speed auto transmission and the whole engine combo delivers a powerful but elegant on-road experience.
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.
The official combined (urban/extra-urban) fuel cycle figure is 11.9L/100km, which is lower than its rivals.
My real world usage sits at 12.3L/100km after a mix of open-road and urban driving.
This result is decent for a performance SUV but expect it to be thirsty in an urban environment as the on-board gauge hit the mid-20s in the city.
Based on the large 85L fuel tank theoretical driving range is 714km and around 690 using our real-world result. Respectable for a performance SUV but not as good as some family SUVs.
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.
The SQ8 delivers on power because it’s effortless to get up to speed and the pick up is super responsive when the start/stop function is turned off (otherwise there can be some lag).
The engine doesn’t sound like a big and grumbly V8, though. There are some growls but it’s mainly when you turn the engine on and not to be obnoxious about it but if you're in a V8, you want to hear it as it’s part of the fun of having a big bruiser engine like this!
What doesn’t help the V8 soundscape is the fact the cabin sounds like a noise-cancelling headphone inside. There is a small hum from road noise but it’s pretty darn quiet. Almost EV quiet at times but that means the driving experience leans more towards refined and elegant rather than sporty and fun.
The SQ8's handling is great - super direct steering, stable in corners and well-rounded passenger comfort when it comes to suspension.
You still get road feedback, which I like as a driver, but it’s not too stiff thanks to the adaptive suspension.
The SQ8 is a large car but you wouldn’t know it when it comes to parking. The 360-degree view camera is clear and the dynamic guidelines help you to position this big unit even the smallest of car parks.
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 SQ8 has a maximum five-star ANCAP safety rating from testing done in 2019 and features eight airbags, including side chest airbags for both rows. It's common to only find the latter in the front – so that’s great for a family car.
The SQ8 scored well across its ANCAP individual protection segments, scoring 93 per cent for adult occupant, 88 per cent for child occupant, 71 per cent for vulnerable road user and 75 per cent for its safety assist.
The SQ8 has a long list of safety features including blind-spot monitoring, safe exit warning, driver attention monitor, fatigue reminder, matrix LED lights, SOS call, forward collision warning, rear collision warning, rear cross-traffic alert, lane keeping/departure aids, tyre pressure monitoring, adaptive cruise control (with stop & go and lane keeping), park assist and a 360-degree reversing camera plus front and rear parking sensors.
The rear row features two ISOFIX child seat mounts and three top tether anchors.
The SQ8 has AEB with car, pedestrian, and cyclist detection and is operational from 10 – 250km/h but it is usual to see this system operate from as low as 4.0km/h.
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 SQ8 comes with a five-year/unlimited km warranty, which is a normal term for the class.
It also comes with capped servicing for five years or up to 75,000km and averages $920 per service, which is very good for the segment.
Servicing intervals are reasonable at every 12-months or 15,000km, whichever occurs first.
