Jeep Gladiator vs Mercedes-Benz G580

What's the difference?

The Jeep Gladiator Rubicon is a very capable off-roader and it's not as terrible on-road as some people might assume.

But while it's a whole lot of fun to steer around on the dirt, it lacks the versatility, safety tech, and refinement that would shift it from simply being a decent hard-core 4WD ute to a good general-purpose vehicle.

However, by focussing on those factors, you're in danger of missing the Gladiator's point entirely. This is a purpose-built 4WD fun machine, which is perfect for its intended use. But, the problem is, it's not perfect, or even very good, at anything else.

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.

The Jeep Gladiator appears built for purpose if your purpose is to head bush and have fun. And in Rubicon form it sure looks like it's capable of tackling hard-core 4WDing.

The Gladiator looks very much like its stablemate, the iconic Wrangler, with its chunky front end and blocky body.

It has more than the inkling of a US-style pick-up's presence at 5591mm long (with a 3488mm-long wheelbase), 1894mm wide, 1909mm high, and with a kerb weight of 2242kg.

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.

You have to give Jeep's designers credit because they know their outdoorsy stuff. The Gladiator's interior is nothing if not practical.

The ute has a squared-off and action-ready interior that seems up to the task of copping the dirt of an outdoors life.

The cabin feels like it's water- and weather-proof, even if that may not literally be the case. 

It's a snug interior and build quality generally feels solid.

The 8.4-inch multimedia touch screen is clear and easy enough to read while on the go, but it's too small. The Jeep's 'Uconnect' system is simple enough to get your head around and Apple CarPlay and Android Auto are easy to get working.

There's also a 7.0-inch LED driver-information display, which shows tyre pressure, tyre-fill alert, digital speed readout and more.

All controls, dials and switchgear are chunky, making for easy operation, no matter how bumpy the terrain you're traversing is.

The reach-and-rake-adjustable steering wheel incorporates audio, voice and cruise control controls.

Storage spaces are few, but at least they're well suited to adventure, such as tensioned mesh pockets on the doors and seat backs and small spaces with textured bases for your bits and pieces.

There are two USB-A ports and a USB-C port up front and two for back-seat passengers. There's also a 230V outlet up front on the centre console.

Seating is decent all-around but anyone taller than Tom Cruise's stunt double has to mind their head so they don't thump it on the unforgivingly hard ceiling of the detachable top.

There's a shallow storage space under the rear seat and, when that 60/40 split rear seat is folded flat, there are LED lights behind to illuminate the narrow storage space in the rear of the cabin, where there are also storage nets.

The tub's load space is 1442mm wide – 1137mm between the wheel arches so not wide enough for a pallet – and it is 1531mm long. Load height is 885mm at the tailgate.

The tray has integrated tie-down points and under-rail LED lights.

Payload is now a claimed 693kg, which is better than its previous 680kg but still rather ordinary when compared to a lot of dual-cab utes available in Australia.

Gross vehicle mass and gross combined mass are listed as 2935kg and 5656kg, respectively.

The Gladiator has a maximum towing capacity of 750kg (unbraked), and its 2721kg braked towing figure is a let-down against the 3500kg capacity of most other rivals.

This is a ute better suited to weekend camping trips than load-lugging work duties.

Another bonus for tourers though: the spare wheel is a full-size steel one.

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.

The new Mercedes-Benz G580 is priced at $249,900 and a more highly-specified limited Edition One version comes in at $299,900, both before on-road costs.

That’s a price territory where the BMW X5 and X6 M Competition ($244,900 & $250,900) as well as the Range Rover Autobiography ($233,961) live. Not to mention competition from the G580’s still available and appreciably pricier twin-turbo V8 Mercedes-AMG G63 stablemate ($365,900).

As you’d expect, the standard features list is substantial and the highlights are Burmester 3D Surround Sound audio (with digital radio), leather upholstery, keyless entry and start, a multi-function steering wheel trimmed in Nappa leather, power front seats with memory function, heated and cooled cupholders, and wireless smartphone charging. 

There’s also dual 12.3-inch driver instrument and central media displays, ambient lighting and adaptive LED headlights as well as Android Auto and Apple CarPlay.

As well as cosmetic changes, covered shortly, the Edition One steps up to ‘Silver Pearl’ and black Nappa leather trim (with blue contrast stitching).

There’s also a range of optional packages bundling up everything from exterior body elements to interior trim and additional multimedia, the latter especially for back-seaters. 

The ‘Night Package’ ($4300) includes black exterior mirror housings, black running boards and wheels as well as darkened exterior lights and a radiator shell that can be illuminated for an impressive profile while driving.

A ‘Superior Line Interior Plus Package’ ($14,500) brings full Nappa leather upholstery, ‘Active Multicontour Seat Package Plus’ and grab handles in leather. Then a ‘Manufaktur Exterior Package’ ($4100) finishes the roof, bumpers and wheel arches in ‘Obsidian Black’. 

But the one that will score you maximum brownie points with the kids is the ‘Interior Comfort Package’ ($8500), featuring a rear seat entertainment system, including two integrated 11.6-inch touch displays.

The Gladiator Rubicon has the Wrangler's 3.6-litre Pentastar V6 petrol engine (209kW at 6400rpm and 347Nm at 4100rpm) and eight-speed automatic transmission.

The V6 has a lot of punch for on- and off-road driving and plenty of low-end torque for low-range 4WDing and, matched with the eight-speed auto, it's a well-proven team-up that consistently works well.

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’.

The Gladiator Rubicon has listed fuel consumption of 12.4L/100km on a combined cycle. 

On test I recorded actual fuel consumption of 12.9L/100km, from fill to fill.

The Gladiator has an 83-litre tank, so, going by my on-test fuel-use figure, you could reasonably expect a driving range of approximately 643km from a full tank.

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.

It's certainly an experience, but the Gladiator is not as atrocious on-road as you may assume.

This vehicle is a lot of fun to drive because it demands a lot of attention and input to keep it on target.

The steering is floaty, with plenty of play in the wheel and understeer through corners, and there's a fair bit of tyre rumble from the BFG muddies.

The wing mirrors generate noticeable wind noise, but the Gladiator's not as awkward or unrefined as you might expect.

Because it's essentially a stretched Wrangler – with a 787mm longer body and a 480mm longer wheelbase than its stablemate – the Gladiator has a solid stance on the road and, for such an unashamedly off-road-oriented vehicle, it feels even more settled and composed than the Wrangler does on sealed surfaces.

This 2242kg ute is built for tough fun with a body-on-frame design and reinforced chassis, but the Gladiator manages to be nimble around town.

Ride quality is generally impressive with this ute cruising comfortably on live axles front and rear with coil springs and, in 2023 onward versions, Tenneco shocks all-around rather than the previous Fox Shocks set-up.

Aspects of the Gladiator experience will annoy some people. Visibility is compromised in all directions, the throttle is touchy, the 13.6m turning circle may add a degree of difficulty in attempts at fast turnarounds (on a city street or in a busy country pub car park) and all that driver attention and input the Gladiator demands of its steerer will become tiresome for a few drivers.

But, as expected, the Gladiator's true spirit is only ever fully revealed when you head off-road. It's a hell of a lot of fun in the dirt. Drop tyre pressures, do up your seat belt and let the Gladiator off the leash.

The 'Trail Rated' Gladiator is loaded with off-road mechanicals, from a 4X4 system with 4:1 low-range (contributing to a 77.2:1 crawl ratio), front and rear diff-locks, heavy-duty Dana 44 axles (front and rear), sway-bar disconnect and BFGoodrich Mud Terrain tyres, as well as a stack of driver-assist tech aimed at making you feel like Australian 4WD expedition legend Ron Moon.

Shocks engineered for off-roading add a welcome dimension of comfort and handling to the Gladiator on fast dirt and gravel tracks on the way to your chosen off-roading destination.

That 77.2:1 crawl ratio means nothing to most of us until you have the opportunity to experience the feeling of all that terrain-gripping torque for yourself.

In 4WD low-range first gear, and with both diffs locked, the Gladiator feels unstoppable. It climbed with ease a short steep rocky hill where I've seen drivers of modified vehicles opt for the ‘chicken' tracks either side.

The only thing is, because of the Gladiator's 3488mm-long wheelbase and 18.4-degree ramp-over angle, there's a real risk of bellying out or at least grinding the undercarriage on earth when you crest these steep hills, which is why you must drive with concentrated focus.

But that's part of the fun. It really is a driver-direct experience. You need to be aware of everything that's going on, you never feel like you're one step removed from the situation, or the terrain or the consequences of your driving… you feel dialled into the terrain and that's guaranteed to put a smile on any 4WD enthusiast's face.

Besides, the Gladiator does have substantial underbody skid-plates, protecting the fuel tank, transmission and transfer case, as well as heavy-gauge tubular steel rock rails to soak up off-road hits.

With an approach angle of 40.7 degrees, a departure angle of 25.1 degrees and a listed ground clearance of 249mm and a wading depth of 760mm, the Gladiator has decent off-road measures.

Suspension travel is okay, but to get even more stretch, you can hit the sway-bar disconnect button to drop a wheel to the dirt – or as close as possible depending on how deep the ruts are.
 
The Gladiator has 'Selec-Speed Control' (effectively an adjustable low-speed cruise control for 4WDing that can be set between 1.0-8.0km/h), and 'Off-Road+', which tweaks throttle and traction control, among other systems, to best suit the terrain.

It also has a forward-facing off-road camera so the driver has a chance to see any obstacles that might otherwise go unnoticed until it's too late, such as branches, rocks, tree stumps and hard rubbish.

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.

Although the Mercedes-AMG G63 carries a maximum five-star ANCAP safety assessment from 2018, the pure-electric G580 is unrated. But crash avoidance tech includes active cruise control, ‘Active Steering Assist’, high-speed AEB, traffic sign recognition, lane-keeping assist, blind-spot monitoring, driver fatigue monitoring as well as a 360-degree camera view and ‘Active Parking Assist’.

And if a crash is unavoidable, there are no fewer than 11 airbags on-board, including driver and front passenger front and side, rear side, full-length curtains, driver and passenger knee and a front centre bag.

There are three top-tether points for child seats across the second row, with ISOFIX anchors on the two outer positions.

The Gladiator has Jeep's five-year/100,000km factory warranty, five-year capped price scheduled servicing, and lifetime roadside assistance.

The first five services are capped at $399 each and scheduled servicing is due every 12 months or 12,000 km, whichever comes first.

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.
