Jeep Grand Cherokee vs Mercedes-Benz GLE-Class

What's the difference?

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.

If you can get past the relatively steep asking price, the design appeals to you, and its slightly last-gen ergonomics work for you, then there’s a lot to like about the GLE. It’s a big, capable and comfortable cruiser, but given there are cheaper and more efficient options around, it would be a decision of the heart rather than the head.

As with any vehicle, some will like it, some won’t, and some simply won’t care all that much. 

The 4xe certainly has a distinctive Jeep look to it.

A few exterior design cues hint at its PHEV leanings: the plug-in point on the front left-hand panel and a ‘4xe’ designation on the rear door.

The GLE hasn’t changed massively since 2019, but sleeker lights and some tweaks around the face have helped it age relatively gracefully. As much as a 2.4-tonne SUV can be graceful.

There are still references to the original ML-Class the GLE succeeded, like the ‘coupe’ shape of the C-pillar that betrays the true SUV shape of the GLE.

The reshaped front-end has less black plastic on show, and its grille stays true to the pre-facelift design.

Inside, it’s just the steering wheel that’s new, everything else holds up well in terms of a design that’s also practical, though some would say it looks outdated given the many physical controls.

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 GLE is very easy to use because of those physical controls.

Save for the trackpad in the centre console that can be used like a laptop’s control mat - it’s a little fiddly - everything is easy to locate and adjust and the controls feel nice. The switches along the climate control row all feel nice and clicky, buttons in the centre console are big and obvious, and even the steering wheel’s haptic buttons are laid out sensibly.

The touchscreen’s software has been updated since launch during the facelift and it’s easy to navigate, but wireless Android Auto or Apple CarPlay are a good workaround.

The front seats, as well as being comfortable, are adjustable to an impressive degree for finding your driving position and there’s plenty of room and light to make the cockpit feel airy.

Storage isn’t at a premium, there’s plenty of space in door cards, the central storage bin, and the cupholders and phone charger can be hidden away.

Behind the front row, rear seat space is ample, though if you opt for seven seats the second row can be moved to accommodate a third row of passengers when needed.

In our test car, that isn’t the case, so the GLE’s cavernous 630 litres of boot storage is available. The second row can split 40/20/40, which is convenient for loading long items while four passengers are present.

Oh, but under the boot floor, despite some extra room for bits and pieces, no spare tyre. Big marks down for a car that absolutely has the space for one.

It’s not a strong start for the GLE. Our top-spec (non-AMG) GLE 450d 4Matic variant starts from $154,900, before on-road costs, while our test car has $3800 of option boxes ticked.

So, $158,700 before on-roads as-tested, the GLE is this borderline prohibitively expensive for what it offers.

If the car you’re after must be diesel, the options are still many in terms of rivals… especially if you’d like to save a few dollars.

Moving on from the big Mazdas and VW Touaregs to the proper premium badges, and there’s the $136,815 Audi Q7 50 TDI (if we exclude the $120,530 base Q7 TDI) or the BMW X5 30d for $138,600. Even a Range Rover Sport D300 comes in under the GLE at $159,481.

For a seven-ish year old luxury SUV, the GLE does a decent job of hiding its age in some ways, but there are gaps.

The twin 12.3-inch screens for multimedia and driver display have aged well, plus there’s electrically adjustable leather front seats with heating, though the leather in our new test car needs some softening up. Perhaps over time.

The new steering wheel comes thanks to newer models in Merc’s line-up, though haptic controls can be accidentally bumped (as opposed to buttons).

Wireless phone charging, wireless Android Auto and Apple CarPlay, a head-up display, a huge sunroof, LED interior lighting, adaptive high beam headlights, a power tailgate and surround-view parking cameras are all standard.

Optionally, there’s a set of 21-inch wheels as pictured on our test car. They’re $2400 and you’d probably be better off with standard 20-inch wheels for the extra comfort.

The illuminated running boards are a $1400 option, and they’re also probably not necessary. But I’m not your mum, go for it if you want.

Oh, and you can also have the GLE in seven-seat form, but our test car is a luxuriously spacious five-seater.

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 GLE 450d’s 3.0-litre inline six-cylinder diesel engine is turbocharged, with a healthy 270kW and a brawny 750Nm to its name. That torque peaks all the way from 1350rpm to 2800rpm, by the way. Handy.

A nine-speed automatic transmission sends drive to all four wheels ('4Matic' in Merc-talk), while a 48-volt ‘mild-hybrid' system ('EQ Boost' in Merc-talk) means take-offs and shifts are aided by a bit of electric power.

Mercedes says the GLE can dispatch the 0-100km/h sprint in just 5.6 seconds, and that feels about right.

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.

Mercedes claims a 7.4L/100km combined cycle (urban/extra-urban) fuel consumption figure for the big lug, but achieving that and making the most of its large 85-litre tank is a challenge.

We averaged 8.7L/100km on test but the trip computer showed as low as 8.0L/100km at one point. Get the GLE on the highway and fuel use plummets.

Theoretically you should be able to get about 1150km from a single tank, but realistically we wouldn’t plan trips any longer than 900km between fuel stations. 

Still impressive, given that’s about the distance between Melbourne and Sydney, or Sydney and Brisbane. Roughly.

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.

A trip in the GLE feels like a welcome step back in time. Sure, coming in close to five metres long and two-and-a-half tonnes means it’s not a nimble steer, but the GLE strikes a nice balance of comfort and tactility that’s getting rarer.

None of it feels particularly sharp in terms of inputs or feedback, but it’s easy and predictable to a point where even winding back-roads are effortless to flow through.

The big diesel engine feels almost lazy, but it’s just so effortless in getting things moving as it strives to sit close to idle whenever possible. Because of that, there’s little noise from the engine bay even under reasonable acceleration, and the powertrain is helped by that 48-volt system which makes stop-starts from the lights super-smooth.

The mild-hybrid also helps smooth out power delivery, to the point where the only time the GLE feels clunky is the occasional lag when shifting from Drive to Reverse or vice versa.

The test car’s suspension isn’t the optional airbag set-up, but the non-adaptive steel does fine in terms of comfort and soaking up harsh surfaces. And even the big 21-inch wheels aren’t too bad over sharp bumps.

With smaller wheels (more tyre cushioning) and the air suspension, it feels like the GLE would ride gorgeously.

Its body control is predictable on smooth roads, and if you’re careful you steer the hefty SUV through tight, winding roads easily, but consistently rough surfaces can make the GLE feel unsettled for a short period of time.

There’s an overall softness to it that means gentle off-roading is possible, and the tyres are thick enough to make it comfortable. You won’t find yourself being tossed around on a flat enough gravel road.

There’s a lot under the skin in the GLE in terms of safety, and it doesn’t always make itself known. This is a compliment.

The GLE scored a maximum five stars in its ANCAP assessment in 2019, and though the criteria has changed significantly since then, it feels like it should still score well.

The GLE doesn’t intervene unless it needs to, but the ability is there for the big Merc to avoid incidents and employ many means to protect passengers and pedestrians alike.

A warning for the driver and a gentle seatbelt tension comes in before the car slams on the brakes, though if no action is taken before an expected collision the GLE will drop its AEB anchors.

There are nine airbags if it all goes pear-shaped, plus some well-tuned adaptive cruise control with lane keep assist and departure alert, there’s traffic sign recognition with that, too.

Blind spot warnings, front- and rear cross-traffic alert, front and rear parking sensors and driver monitoring are joined by Mercedes’ plethora of other little safety features that minimise impact and damage in a crash.

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.

Servicing isn’t cheap at Mercedes, even in the context of this market segment. A three-year service plan for the GLE costs $4045, while five years is $8055. That’s $1348 or $1611 per service respectively. The later services in those five years will of course be much more expensive and bring the average up.

Intervals are every 12 months or 25,000km, but Mercedes’ five-year/unlimited-kilometre warranty means anything major that goes wrong in that time should be covered - always read the fine print.
