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.
Car companies don’t normally overhaul a vehicle so rapidly and comprehensively. But the updated Subaru Solterra EV is an exception. It had to be done and this isn’t just an update, it’s an act of survival for Subaru… and Toyota.
You knew the Solterra’s identical twin is the Toyota bZ4X, right? Together Subaru and Toyota developed an electric SUV. Subaru’s is the Solterra, Toyota’s is the bZ4X - same car, different styling, mostly.
The problem was the vehicle couldn’t compete with rivals like the Zeekr 7X and Tesla Model Y on price, driving range, power or charging speed.
Subaru and Toyota knew this had to be fixed ASAP. And so we now have the new Solterra. But is this revised version good enough? Read on to find out.
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 updated Subaru Solterra is now good enough to compete with rivals such as the Tesla Model Y and Zeekr 7X. The price is right as are the driving range and motor outputs.
There's room for improvement in terms of cabin packaging. The car doesn’t cater for taller, larger people up front, with the steering wheel placement and wide centre console. Cabin storage could also be much better.
Still, the Solterra is superb to drive. One of the best EVs I’ve piloted at this price.
The Solterra is a mid-sized SUV with sporty coupe-like styling and this update has seen the front of the car receive a new look which to my eyes is better than the previous face.
The rest of the car’s exterior remains mainly unchanged in the design.
If you aren’t a fan of the Solterra’s look then check out Toyota’s bZ4X, which is its twin and has slightly more conservative styling, and while I do like the Subaru’s face, I think Toyota’s tail-light treatment is cleaner.
The cabin is modern with a large central media screen, a high-placed instrument display and a wide centre console with dual phone chargers. But the squareish steering wheel steals the show, completing the futuristic vibe.
This update has seen the centre console re-designed with the dual chargers added and the gear-shifter moved backwards away from the media display.
The cabin doesn’t have much in the way of glitzy touches, with dark materials dominating throughout. Hard plastics abound, but the interior still looks and feels premium.
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 steering wheel’s square design is like that for a reason - it’s designed to provide the driver with a clearer view of the instrument cluster. But as noted in the past with other vehicles that choose this set up, the ergonomics don’t work for everybody - especially if you’re tall like me (I’m 189cm).
In my case the top of the steering wheel obstructs my visibility of the display, which shows vehicle speed among other crucial info.
There’s also a problem with the clearance of the steering wheel and my legs. This is caused by a combination of my height, the low steering wheel and the limitations of how much it can be raised, the low-hip point in the seating position and the shape of the wheel.
Add an overly wide centre console and space for larger and taller drives becomes even more cramped.
Moving the shifter back in this update also makes it more difficult to use for me and the mechanism is quite clunky.
Second row space is a much better story, with a flat floor, good headroom and lots of legroom even for me behind my driving position. The rear door aperture isn’t great and this has made installing child car seats and the corresponding child difficult.
Cabin storage could also be better. There’s no glove box, but there is space under the centre console, although this is now where the large driver’s manual lives. There’s a large centre console bin, big door pockets and four cupholders (two up front and two in the second row).
The second row has directional air vents and USB ports. There are USB ports up front, too.
Boot capacity isn't enormous at 421 litres in the entry-grade and 410 litres in the Touring. There’s no front boot, either. Under the bonnet is the Solterra’s front motor and electrical hardware.
The Solterra is a five seater SUV, so no third row here.
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 Solterra is offered in two grades. An entry-grade model, simply called Solterra, lists for $63,990 and above that is the Solterra Touring for $69,990. That’s up to seven thousand dollars more affordable than pre-update.
We tested the top-of-the-range Touring, which comes loaded with standard features, the only option being leather seats.
If you were wondering if you needed to spend the extra money on the Touring you might be pleased to know both grades have exactly the same powertrain and the entry-grade comes with plenty of standard features.
Coming standard on the entry grade Solterra are 18-inch alloy wheels, LED headlights and LED tail-lights, power mirrors, puddle lamps, a powered tailgate with kick-sensor (new with the update) and roof rails.
There’s also synthetic leather seat trim, heated and eight-way power-adjustable front seats, a heated leather steering wheel, heated second row seats, dual-zone climate control, a 14-inch multimedia touchscreen (new) and 7.0-inch driver display, wireless Android Auto and Apple CarPlay, dual wireless phone chargers (new) and a six-speaker sound system.
The Solterra Touring comes standard with all this but adds 20-inch alloy wheels, a panoramic sun roof, ventilated front seats (new) and a 10-speaker Harman Kardon sound system.
The Touring also features a 220V vehicle-to-load (V2L) power outlet.
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.
The Solterra has two electric motors and as before there is one driving the front wheels, and one driving the rear wheels for all-wheel drive. Toyota’s bZ4X twin can be had in two-wheel drive and AWD.
The big news is the motors are now more powerful. Much more powerful. Combined output is 252KW (up from 160kW). That’s a huge increase but power is still less than the output of a Model Y or Zeekr 7X.
The front motor now makes 167kW/268Nm, while the rear motor produces 88kW/169Nm. Acceleration from 0-100km/h is about five seconds and that’s almost two seconds faster than the old version.
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 updated Soltera’s battery size has increased to 74.7kWh. That’s up from 71.4kWh and means driving range has increased.
The new, larger lithium ion battery delivers a range of 566km (WLTP) in the entry-grade Solterra (up from 414km). That addresses a big concern about the old car. The Touring has a range of 517km and any range above 500km is acceptable in my book.
Also big news is the increase in maximum AC charging capacity from 11kW to 22kW. DC charging capacity is the same at 150kW with 0-80 per cent charge in about 30 minutes.
Consumption officially ranges from about 14.6kWh/100km in the entry-grade Solterra to 16.0kW/100km in the Touring. The Touring we tested was reporting 17.0kW/100km according to the trip computer after 163km of testing in mainly urban conditions.
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 Solterra may slightly lag behind rivals in some areas such as range and power output, but where most rivals can barely touch it is when it comes to driving.
Currently there aren’t many electric vehicles that are good to drive, except for more prestige offerings from brands such as BMW, Mercedes-Benz and Porsche.
The Solterra is one of the best electric vehicles I have driven at this price point and it’s down to the outstanding platform it shares with the Toyota bZ4X which provides superb ride comfort, great handling and excellent steering.
Acceleration is strong and traction from the all-wheel drive is good.
Sure, while the driving position needs improvement, the car itself is excellent to drive.
Visibility is also good and sound intrusion is minimal. We noticed some materials making noises in the cabin. Although this is common, with no engine to mask it, it becomes more noticeable in EVs.
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 Solterra has been awarded the maximum five-star ANCAP rating - but that was given under 2022 testing criteria and the bar has been raised quite a lot higher since then.
Still, the level of safety technology is high with AEB, lane keeping assistance, blind spot warning and rear cross traffic alert onboard.
Front and rear parking sensors are standard on both grades, as is a 360 degree camera view. Auto parking is standard on the Touring.
A digital rear vision mirror is also standard on both grades providing a clear and unobstructed view.
There are seven airbags present, including a front centre bag. And there are three child seat top tether points across the second row with ISOFIX anchors in the two outer positions.
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 Solterra is covered by Subaru’s five-year, unlimited-kilometre warranty which is falling behind the seven-year warranty offered by many now. The battery is covered by an eight-year, 160,000km warranty.
There is also five years of capped price servicing with each yearly/15,000km service costing between $130-$300. That’s a very reasonable price.
