Mercedes-Benz G-Class vs Jeep Gladiator

What's the difference?

As per the 1979 original, the current G-Class is produced by Magna Steyr in Arnie’s home town of Graz in Austria. And many fundamental things haven’t changed since then. But clearly this EV monster’s exotic electric powertrain is a huge departure.

It retains impressive off-road ability and straight-line speed. But will it hit the mark with top-end luxury 4WDers? Short story, this thing is wild, and it will be irresistible for a likely narrow band of tech-focused ‘must have the latest and greatest’ buyers. Nothing like impressing friends and family with a tank turn.

Note: CarsGuide attended this event as a guest of the manufacturer, with travel, accommodation and meals provided.

The Gladiator is far from the most practical, versatile, or sensible dual-cab on the market. Not going to lie, though. This is the most fun I’ve had in a ute in a long time.

Okay, so Mercedes-Benz says, with a straight face, that “with the aim of optimising the vehicle’s aerodynamics” classic G-Class elements have been revised, including the reprofiled bonnet, ‘air curtain’ vents in the flares over the rear wheel arches, A-pillar cladding and the small spoiler on the edge of the roof.

At the same time, the 20-inch wheels are also claimed to be "aerodynamically optimised” and underneath, a 26mm underbody casing made from a mix of materials, including carbon-fibre (attached to the ladder frame with more than 50 steel screws), protects the battery from dust, dirt and rocks.

In ticking off the Edition One, car-spotters should look for black rims with blue brake callipers behind them, blue inserts in the exterior protective strips as well as black door handles and a new rectangular design box on the rear door for storing items such as charging cables, tools or snow chains. If you want a spare wheel, choose the standard model.

An optional black-panel radiator grille ($3800) features tinted lighting units as well as an animated LED light band and chrome surround. The light band can be activated as a running light or an animation when locking and unlocking the vehicle.

And it’s worth noting Mercedes-Benz and the car’s contracted manufacturer, Magna Steyr, have invested much time and many Euros in retaining the car’s classic handle and door lock design. G-Wagen owners will recognise its sound from several kilometres away.

Inside the G580 it’s clear this is one area where the G-Class has progressed enormously over the decades. It’s still quite upright in terms of the dash design, but you’re confronted by twin 12.3-inch screens, supporting the Mercedes-Benz user interface. 

All very high-tech, but that’s balanced by an old-school grab-handle for the front passenger to latch onto during off-road work. 

The signature turbine-style air vents are located within squared-off panels, and in the limited Edition One you have a blue fleck running through carbon-fibre inserts on the centre console, door cards and that front grab handle. In the standard car it’s a (very attractive) walnut open-pore wood rather than carbon.

A luxurious interior for sure.

Despite a legion of trendy retro-styled off-road pretenders, from the Ineos Grenadier to the GWM Tank 300, there’s nothing quite like the original Jeep style which the Gladiator shares with its Wrangler sibling. Unless you’re Mahindra which has technically been producing Willys Jeep successors for longer, but that’s another story for another time).

The new Rubicon looks a bit more swish in 2026, with the body coloured wheel arches and a tweaked grille which is now wider and shorter. The two-tone roof which was previously optional is now standard.

It looks rugged, tough, and undeniably classic, with the mud terrain tyres sealing the deal.

Of course, you can’t forget the many so-called ‘Easter eggs’ Jeep hides about the place. In the case of the Gladiator, these include a silhouette of a Willys Jeep climbing up the driver’s side windscreen, a gorilla imprint on the opposite side signifying the windscreen is now constructed from the same stuff designed to make your phone scratch-free. The tray features imprints of dirtbike tyres where you might want to strap two in and even the recirculate button on the climate unit is in the shape of a Wrangler. Nice touch.

On the inside generally, it feels like a purpose-built vehicle in much the same way as an old Defender. It leaves you with a sense of how genuine it all is, with loads of physical switchgear and an overall shape meant to replicate the no-nonsense appeal of Jeeps dating back to the Willys.

For the record, the G63 is just over 4.6m long and a little more than 1.9m wide with a 2890mm wheelbase. So, not huge, but its close to 2.0m height is hard to ignore. 

In the front there’s lots of breathing space, and in terms of storage you have generous bins in the doors with plenty of room for big bottles. Then there’s a centre armrest, which doubles as the top of a deep storage box housing a USB-C port inside. 

A sliding roller cover in the centre console reveals two cupholders, another two USB-C sockets, a 12-volt outlet and a wireless charging pad. Add in a big glove box and you’ve got plenty of options in terms of storage, power and connectivity. 

In the back, sitting behind the driver’s seat set for my 183cm position I’ve got tons of foot and legroom and, no surprise, lots of headroom.

There’s a fair bit of sculpting in the rear seat, which is as nice as it is unusual (makers often avoid bolsters on the rear seat as it makes the backrest harder to fold flat). And in terms of three-abreast accommodation, a smaller adult will be okay in the centre spot for shorter journeys. Three up to mid-teenage kids will be swimming in it.

Then, for practicality you again have generous bins in the doors. And if you need even more capacity, fold down the centre armrest which houses two different size cupholders. 

In the rear of the centre console you’ve got two USB-Cs, a 12-volt power outlet, individual climate control and directional vents.

There are map rockets on the front seatbacks and more air vents in the B-pillar. So, when it comes to comfort, powering up devices and storing ‘things’ you’re well taken care of.

The side-opening tailgate door opens from right to left, which isn’t ideal when parallel parked on the left hand side of the road, but boot volume is over 600 litres (VDA) with all seats upright, expanding to nearly 2000 litres with the 60/40 split-folding rear seat lowered.

There are multiple tie-down hooks, a netted pocket, two lights, a 12-volt outlet as well as a ‘ski-port’ door and sliding cargo cover to enhance practicality and security.

As mentioned earlier, the full-size spare in the standard model, but the Design Box replaces it on the Edition One, although Mercedes-Benz says it’s aiming to make a spare available as an option later in the year.

However, also like an old Defender, the Gladiator’s interior is full of compromises to maintain its iconic design.

The seating position is awkwardly high, which is fine when off-roading, but can be limiting when you’re just driving around a city, and the footwell is half taken up by a transmission tunnel so there’s nowhere to rest your foot.

The door cards are pretty basic because the doors are removable (although Jeep stresses this is only legal on private property), but elsewhere there’s much-appreciated levels of functionality in an era of touch-based controls.

The centre control panel, for example, features physical dials for high-use functions and toggles or buttons for everything else. It’s mercifully easy to use and old-school motorists will also love the physical shifters for gear selection and the transfer case alongside. And an analogue handbrake is an increasingly rare sight.

There are even buttons we didn’t ask for, like the four pre-wired auxiliary switches, and while the dash trades away a fully digital panel for a digital supervision screen with analogue dials either side, it suits the character of the car.

It’s not the most comfortable space to be in, however. Not only is the seat base super high off the ground, but despite the Gladiator’s imposing dimensions the front seat somehow feels narrow.

Storage is okay, but not on the same level as many rival utes. The basic doors score nettings on each side, with two deep and useful bottle holders in the centre console. The armrest box is two-tiered which is handy, and there’s a small glove box. Outside of this, there’s not a lot of storage up front.

The rear seat is decent when it comes to space for the ute segment, although it is also very high off the ground and hard to clamber into thanks to the way the rear door is shaped. Once you’re in there, be sure not to smack your head on the frame, which seems like it could be an easy thing to do.

Again, nets feature in the doors, with two more nets on the backs of the front seats, which also feature luggage hooks. There are dual adjustable air vents back there and two bottle holders moulded out of the centre console. They're nicely-sized, but will eat into the legroom of any adult you want to put in the centre rear position, making it extra cramped if you have three across.

The back seat features some things I’ve never seen before, though. There’s a huge storage area underneath the seats with its own lid, and some limited storage space behind the seat backs which features a removable Bluetooth speaker which also automatically re-charges when it’s docked back there. Cool.

The rear window features an opening port, which is also rare, while all the main storage compartments are lockable for when you want to leave the car with the roof and/or doors off.

Capacities and payloads have never been a strong point for the Gladiator. The tray measures 1531mm long, 1443mm wide and 1137mm between the arches, making it unable to fit a standard-sized Australian pallet. The payload is also limited at just 693kg, far short of the close-to-one-tonne many work-focused dual-cabs can hit.

However the tray isn’t for show only, featuring an array of useful tie-down points and a built-in rail system to help secure all sorts of objects. There are even steps built into the rear bumper design for easier access and a full-size spare wheel underneath.

The braked trailer towing capacity is limited to just 2721kg which is also short of the industry benchmark 3500kg, all of which may limit its use as a work vehicle, or even its appeal as a touring vehicle. I could see how these capacities are easily exceeded with a rooftop tent, recovery gear, a fridge, supplies and at least one passenger.

For this update, the Gladiator has been trimmed down to just one variant, the fully-loaded, top-spec Rubicon.

While the lesser Night Eagle grade has been discontinued, the good news is the Rubicon is now more affordable, starting at $82,990, before on-road costs. Although this still pitches it against only the most expensive mainstream dual cabs.

At this price, for example, you could pick a Ford Ranger in luxury Platinum or sporty Wildtrak form, or even as a plug-in hybrid. However, this car’s classic vibe and purpose-built feel, with a big six-cylinder petrol engine, is more reminiscent of the Ineos Grenadier Quartermaster, which wears a price tag well in excess of $100,000.

While it might be a pricey ute, the Gladiator Rubicon comes with all the gear plus extra stuff for this update, including new 17-inch two-tone wheel designs clad in pricey BF Goodrich mud terrain tyres, Nappa leather seats and a more powerful standard alternator with pre-wired auxiliary switches.

There are also body-coloured fender flares replacing the previous black plastic ones, 12-way power adjust and heating for the front seats, extended soft-touch materials throughout the cabin, a much larger and better-specified 12.3-inch multimedia touchscreen (with built-in nav) as well as wireless Apple CarPlay and Android Auto connectivity. In addition, the LED headlights have picked up an auto high-beam function and the spray-in bedliner for the tray is now standard.

Standard overlanding kit includes the brand’s signature 'Roc-Trac' on-demand 4x4 system, which includes front and rear differential locks, an electronic sway bar disconnect (pretty rare), manually selectable low-range gearing (with a 4:1 ratio), as well as additional underbody protection and rock-slider side steps.

Not enough? This is the only ute on sale in Australia where you can remove the roof and pop the windscreen flat for a full-on Barbie (or maybe Ken) Power Wheels vibe.

The G580 is powered by four permanently excited synchronous motors, each delivering around a CLA200’s worth of power and torque to each wheel for overall outputs in excess of 432kW/1164Nm.

Each motor has its own two-stage transmission and power electronics for almost infinite fine-tuning of the direction and amount of drive sent to individual wheels. Merc calls it ‘individual-wheel drive’.

There’s a relatively massive 3.6-litre non-turbo, non-hybrid ‘Pentastar’ petrol V6 engine under the bonnet, producing 209kW/347Nm. 

Sounds old-school because it is, and it remains the only option for this machine in Australia despite emissions regulations closing in and a 2.0-litre four-cylinder turbocharged engine available in the current Wrangler and overseas versions of the Gladiator.

The V6 is mated to a predictable ZF-sourced eight-speed (torque converter) automatic transmission and drives either the rear- or all four wheels depending on the mode selected.

Housed in a torsion-resistant casing and embedded low down in its ladder-frame chassis, the G580’s 116kWh two-tier, liquid-cooled lithium-ion battery pack delivers a WLTP-rated range of 473km, or 567km on the more lenient NEDC scale.

‘Eco Assistant’ and ‘Range Monitoring’ functions provide continuous information on battery status, energy consumption and estimated range.

Maximum system capacity is 400 volts which enables 200kW DC charging, meaning a 10 to 80 per cent fill in as little as 32 minutes. Maximum AC charging capacity is 11kW.

Claimed energy use is 23.1kWh/100km, and we saw an average of 28.6kWh across urban and highway running on the launch drive program.

Not exactly a ‘green’ EV choice, then, but it’s worth noting a one-year Chargefox subscription is included to off-set the car’s energy appetite.

As you might imagine, the large naturally aspirated petrol engine combines with the over 2.0-tonne Gladiator to make for a relatively steep fuel bill.

Consumption is a hardly-impressive 12.4L/100km on the official combined (urban/extra-urban) cycle, with our car consuming even more - 12.9L/100km - on our three day test covering nearly 500km and with no shortage of freeway time either.

Brim the 83-litre tank and theoretical range is around 670km, dropping to just over 640km using our on-test figure.

So, with 432kW and around 1160Nm, even though the G580 weighs in at around three tonnes, you’re talking 0-100 km/h in 4.7 seconds. And this car gets up and goes… like a beast.

What you don’t get is that traditional Merc-AMG G63 V8 rumble, because, of course, no engine. 

But you do get what Mercedes calls ‘G-Roar’, essentially a sound bar at the front of the car also using the audio system inside to give it what is not exactly an engine noise but some sense of the car progressing. And you can turn it off for completely silent running.

‘Electric Dynamic Select’ changes the parameters of the motors, transmission, suspension, ESP and steering as required. On-road that means ‘Comfort’, ‘Sport’ and ‘Individual’ modes, with off-road comprising ‘Trail’ and ‘Rock’. In the Comfort setting drive flows primarily to one axle for optimum energy efficiency.

Suspension is by double wishbones at the front and a De Dion-style live (rigid) axle at the rear. You’ve got the same adaptive-type set-up as per other G-Class models, so ‘Comfort’ and ‘Sport’ modes and of the many traditional G-Class traits this car exhibits, ride quality is one of them.

Even in Comfort you’ll find even little bumps and thumps making their way up into the seat of the pants and the cabin. It is after all a body-on-frame, ladder-chassis type vehicle and that’s not unusual.  

In terms of steering, it’s accurate and road feel is good. You’ve got 275-wide Falken Azenis FK520 tyres that are more on- than off-road focused. The car feels stable and nicely planted on the road.

The physical brakes are by ventilated discs front and rear, and the big rotors are the same size (353mm) all around. They work nicely and feel like a conventional set-up.

Regenerative braking kicks in as soon as you lift off the accelerator pedal. The powertrain is harvesting energy as the car decelerates and there are four levels you can adjust with the steering wheel paddles up to a quite aggressive level - not quite, but close to a single-pedal set-up.

Off-road, the G580’s ‘G-Steering’ system allows the wheels to turn at different speeds to induce slight ‘drift-like’ oversteer and tighten the turning circle. It works beautifully and the car’s fording depth is 850mm, a full 150mm more than internal-combustion G-Class models.

A three-speed off-road crawl function is adjustable to speeds as low as 2.0km/h, and the car is claimed to remain stable on sideways slopes up to 35 degrees. 

Torque vectoring is used to create ‘virtual diff locks’ and there’s a ‘low-range’ setting. Switch to the ‘Offroad Cockpit’ and data including gradient, lateral inclination, compass readings, tyre pressures and the selected G-Mode appear.

A ‘Transparent Bonnet’ function creates a virtual view of what’s approaching and passing under the front wheels to help the driver pick their way through steep ascents or declines.

For the record, the G580’s approach angle is 32 degrees, departure is 30.7, breakover is 20.3 and ground-clearance is 250mm.

And of course, with the wheels independently powered, the G580’s signature move is what Mercedes-Benz calls a ‘G-Turn’ but the rest of the world calls a tank turn.

If you encounter an obstacle that makes forward progress impossible, the system spins the left- and right-hand wheels in opposite directions so this brute can turn on the spot like an M1 Abrams. You can’t help but crack up laughing when executing this extreme party trick!

In terms of miscellaneous observations around ergonomics and the car in general, it has a 13.6-metre conventional turning circle. So if you’re not using the G Turn function in the car park be ready for a sizeable turning arc.

Also, those aero tweaks here and there seem to have had an effect. Wind noise, especially for such an upright, squared-off design is surprisingly modest. And overall, from a build point of view, this car feels as though it’s been carved from a solid piece of metal. In every aspect it presents as a quality item.

The Gladiator is interesting to drive for many reasons. Mainly, because as a purpose-built off-roader it's a little compromised when it comes to on-road manners.

For example, the high seating position and tapered bonnet shape might be great for visibility off-road, but the boxy design of the chunky A-pillars (designed to keep the car in one piece when the doors roof and windscreen are removed) make it a little difficult to see properly around corners at T-junctions or roundabouts in the confines of a city.

Even proximity of my head to the roof presented a problem when trying to see whether traffic was coming at an intersection with the vehicle angled downhill.

The next alarming trait is how vague the steering is while on the tarmac. It’s an unfortunate characteristic of the Gladiator’s rugged live front axle, making this ute a bit of a handful to steer at low speeds. And it tracks all over the place on the freeway, requiring constant vigilance and steering input from the driver at higher speeds.

It’s also noisy, despite this 2026 version featuring extended sound deadening in the cabin. It needed it. The knobbly mud terrain tyres make their presence felt through a resonant droning entering the cabin at all speeds.

Then, at freeway pace, the wind noise from the Gladiator’s blocky shape picks up. You can feel the sound waves leaking in through the removable doors and plasticky removable roof. There are even silly things like being able to feel reverberations of the sound system through the accelerator pedal.

So, I should hate the Gladiator, right?

Wrong.

This thing is ridiculous amounts of old-fashioned fun. The V6 engine is keen to rev and the transmission lets you ride the gears out, creating a throaty roar and lurching acceleration reminiscent of old Commodores.

While the mud terrain rubber is noisy and offers questionable levels of grip on tarmac or in the wet, the thick sidewall combines with coil springs and chunky Tenneco shock absorbers all-around to make for a pretty decent ride for a ladder-frame vehicle.

In addition, we took the Gladiator for a quick off-highway jaunt as its design intends and it performed as-expected. It has great approach and departure angles, with good visibility for peering over moguls and into ruts or dips.

The mechanical hardware feels up to the task, and while it might slip once or twice as the less sophisticated traction systems (compared to, say, a modern Defender) find their bearings, the Gladiator ate up the moderately challenging trails we found for it.

The chunky tyres come into their own, with the sidewall offering confidence, and the car clambers about with relative ease. Obviously, the enormous 3488mm wheelbase and resulting 18.4-degree breakover angle are the Gladiator’s Achilles heel, making me think twice about cresting certain hills or objects, and making this ute particularly prone to cringe-inducing underbody scraping.

Still, despite its comparatively unsophisticated approach and lack of environmental responsibility the Gladiator is a huge amount of fun to drive.

The previous Gladiator was awarded just a three- out of five-star ANCAP safety rating in 2019, although this updated version gets a few notable upgrades including side curtain airbags, seat reminder alerts and auto high beams.

On the modern active safety equipment front, the new Gladiator scores auto emergency braking, blind spot monitoring with rear cross-traffic alert, adaptive cruise control, roll mitigation as well as front and rear parking sensors and a halfway decent reversing camera.

Not present is lane departure warning or lane keep assist, and given how long the Gladiator is, it would be nice to have a front parking camera, too.

It’s disappointing to see the Gladiator miss key kit like lane keep assist, but unlike a lot of modern vehicles, the Gladiator isn’t annoying to drive and I didn’t find myself needing to turn any equipment off to make it work off-road, either.

The G580 is covered by Mercedes-Benz Australia’s five-year/unlimited-km warranty, which remains the standard offering in the premium part of the market and an eight-year/160,000km drive battery warranty.

Service intervals are every 12 months or 20,000km with service plan pricing available over three ($2645), four ($3980) and five ($4670) years. In approximate terms, each workshop visit will cost ‘around’ $900. Not exactly cheap, especially for an EV, but this is no ordinary electric vehicle.

It’s no secret ownership has long been an awkward topic for Jeep, with models like the Grand Cherokee previously causing all kinds of dramas for owners. A quick scan of forums suggests the Wrangler and Gladiator are less prone to issues compared to their more mainstream siblings in the Jeep line-up. So, food for thought.

Regardless, the Gladiator is offered with a five-year warranty which is distance-limited to just 100,000km, which is well off the pace, although a five-year capped price servicing pack is priced at a reasonable $399 per annual or 12,000km workshop visit.

The brand also offers lifetime roadside assist so long as you continue to service your Jeep in its authorised dealer network.
