Mercedes-Benz G-Class vs RAM 1500

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.

As with all current-generation Ram 1500s, the Rebel remains one of our favourite full-sized American utes on the Australian market.

Yes, it is not cheap, and a few items standard on the Laramie Sport have been deleted for better or worse, but the Rebel offers better off-road capability without losing any of the regular 1500’s driver enjoyment, comfort, refinement and overall class.

An upsized Ranger Wildtrak with more civility than its redneck reputation suggests.

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.

Essentially, the 1500 Rebel is a Laramie Sport with a few changes to make it look a little more athletic.

Changes include an extra power bulge in the bonnet, a restyled grille treatment, black powder-coated steel bumpers, daytime running spot lights, 18-inch rather than 20-inch off-road alloy wheels and the aforementioned one-inch (26mm-ish) suspension lift – partly as a result of the knobblier tyres, Bilstein off-road dampers and revised springs, all for better clearances.

Speaking of which, that’s why the retractable side steps have been deleted. The approach/departure/breakover angles are rated at 20.9, 22.2 and 19.2 degrees respectively.

That the Rebel loses the RamBox does mean a bit more tub width, but at the cost of 210 litres of hidden storage.

What’s left are mostly visual changes, including a two-tone colour scheme with black paint on the lower sections, extra blacked-out trim, Rebel badges and decals and three grade-specific hues: 'Bright White', 'Flame Red' and 'Hydro Blue'.

Dimensionally, the 1500 is definitely in the next-league up compared to a Ranger or HiLux, with length at 5916mm, width at 2057mm (excluding mirrors – that balloons out to 2747mm with them) and height at 2006mm. Wheelbase is set at 3672mm. Which does wonders for interior space.

Inside, a red and black look pervades, resulting in Rebel upholstery and material applications, but the seats and dash remain pure Laramie Sport – and that’s no bad thing, as the DT series remains the most car-like and refined interior of all the big US utes.

Let’s dive in.

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.

This is as much an interior review as anything else, because the Walkinshaw Automotive Group’s engineers have created nearly 50 unique dashboard parts in the 1500’s transition from LHD to RHD.

These join the hundreds of other items that have been modified throughout the big ute.

Haul yourself up and inside, and what you’re met with is essentially a Laramie Sport, but with a more-athletic vibe due to the red-and-black Rebel trim upholstery. In this evaluation example, the presentation, fit and finishes were exemplary.

Everything seems to be in Cinemascope. The sheer girth of the cabin; the excellent vision afforded by lofty seating as well as the deep windscreen and side windows; the abundance of light showering in from the dual-pane sunroof; wide yet cosy front seats that ensconce you like a bear hug – are there comfier ones out there in the world of utes? We doubt it; and heaps of space for your head, shoulders, arms and legs.

Most people should be able to sleep crossways on the back seat floor.

Back up front, the vast multi-layered dash is conventionally designed, with a 12-inch instrument display ahead of the driver and a long, portrait-oriented 14.4-inch touchscreen (containing a superb premium audio system).

But, unusually, there’s also a 10.25-inch multimedia screen for the front passenger, which isn’t visible to the driver for road-safety reasons.

Drilling into the details, there’s a satisfying attention to design to the instrument dials that you’d expect from an Italian brand – Ram owner Stellantis is partly consisted of Alfa Romeo, Fiat and Lancia, after all, as well as Citroen and Peugeot.

It’s also in the feel and quality of the presentation, as well as the general ergonomics, where most of the controls and switchgear are within reach, readily understood and easily operable – after a few moments taken to learn what’s what.

Confidence and swagger, without being too brash or ostentatious. An F-150, in contrast, seems cheap and hard inside.

Weirdly, given all the room around you, there’s also a sense of being a bit hemmed-in, thanks to the ultra-wide centre console. It houses an attic’s worth of storage capability, and is nicely integrated within the overall dash architecture.

It’s a pity, then, that Ram doesn’t offer a three-person bench seat up front – or, at least, a two-person love seat for the passengers right beside the driver’s bucket. There’s certainly enough space for that.

A half-day with the Rebel failed to showcase too many faults or irritations. There’s too much wind noise coming in at speed due to those elephantine exterior mirrors, there’s no digital radio and not everybody will like the red trim inserts. In this regard the vibe is more garish Germanic than restrained Italianate.

Remember, too, the Laramie Sport’s sliding centre console and reclining rear backrests aren’t fitted to the Rebel.

Not that you’d necessarily miss the latter, since the bench is nicely angled and seems comfortable enough. Obviously, there are acres of space to move and lounge about in, and pretty much all the usual amenities are present.

These include USB ports of both varieties, heated outboard seats, face-level ventilation, cupholders, map pockets overhead lighting, a coat hook, and the glorious sunroof that allows so much light to flood in.

There’s extra storage beneath the cushions as well as in the door panels, while a small portion of the back glass slides open. Apparently, that’s handy for hearing and giving instructions when working with the ute. Clever.

And, of course, so is the massive tub out back, complete with a full-sized spare wheel.

For now, Australia only receives the five-foot/seven-inch – or 1.7m long – tub, rather than the longer 6' 1" option offered in earlier 1500s. The Rebel’s payload jumps 30kg, and still maintains its 4.5-tonne towing capacity.

Note that, with the deletion of the RamBox cargo storage units, load-area width increases, but only by 15mm, and you lose 210 litres of hidden tub storage.

For the record, the tub dimensions are around 1700mm (length), 1295mm (width) and 543mm (height). The upshot is about 1500 litres of cargo capacity.

And, of course, there’s the maximum braked towing capacity of 4500kg (with a 70mm ball), 750kg unbraked, 7771kg for Gross Combined Mass (GCM), 3505kg for Gross Vehicle Mass (GVM) and an 893kg payload maximum.

Finally, a heavy-duty tow bar, 12-pin wiring harness and trailer brake controller are standard equipment.

This isn’t a replacement for the bombastic Ram 1500 TRX, which has sadly disappeared along with the classic Hemi V8 (though it may come back sometime in the future), but rather an adjunct to the base Laramie Sport. Just with more off-road sportiness.

Like all 1500s, as well as the conceptually-similar Silverado 1500, Ford F-150 and Toyota Tundra big utes, the Rebel is fully-assembled in the United States in left-hand-drive form, then shipped to and remanufactured in Melbourne for right-hand-drive.

This is no small task, with the Ram boasting hundreds of new and/or modified parts, needing over 80 man-hours of labour in the process.

Hence the high prices – with the Rebel matching the Laramie Sport at $141,950 (all prices before on-road costs).

More than just a sticker pack, the Australian Rebel includes one-inch higher-riding suspension, Bilstein off-road shocks, 32-inch all-terrain Falken Wildpeak 275/65R18 tyres, an electronically locking rear differential, underbody skid plates, a higher payload, special off-road cruise control and a so-called 'Power Bulge' bonnet – though there’s no extra performance under there, sadly, over the Laramie Sport’s existing SST (for Straight Six Twin-turbo).

You’ll need the $159,950 Limited flagship with its High Output SST engine tune for that.

Like the Laramie Sport, the Rebel seems almost sumptuously equipped, and includes goodies like a separate 10.25-inch multimedia display for the front passenger as well as a 14.4-inch central touchscreen and a 12.0-inch electronic instrumentation, 19-speaker Harman Kardon audio, dual-pane sunroof, heated seats front and rear, dual wireless phone charging, a sliding back window, power adjustable pedals and a fully-powered tailgate.

These come on top of a spray-in bed liner, cargo tie-down slider rails, LED headlights, wireless Apple CarPlay/Android Auto connectivity, a reversing camera and front and rear parking sensors. Handy in a truck this long.

There’s also a decent wad of advanced driver assist systems too, like autonomous emergency braking and adaptive cruise control. More on those in the safety section later on.

But it also loses some interior items too, like a sliding centre console, a reclining rear bench and 'RamBox' cargo storage, while digital radio is not available at all… which – to paraphrase '80s punk-rocker Billy Idol – might have Rebel owners yell out for more, more, more!

Anyway, there are also a few things missing outside too that are otherwise standard in the Laramie Sport.

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’.

Underneath the power bulge bonnet is a 3.0-litre twin-turbo in-line six-cylinder petrol engine known as the 'Hurricane'.

Sharing just five per cent of its parts with Jeep’s version, the Rebel uses the Standard Output (SO) tune, meaning this Euro 5-rated direct-injection unit delivers a heady 313kW of power at 5200rpm and 635Nm of torque at 3500rpm.

The High Output (HO) in the Limited, on the other hand, ups the ante with 403kW and 707Nm.

Compared to the old 291kW/556Nm 5.7L Hemi V8, the Hurricane SO lacks its evocative exhaust burble and effortless low-down grunt, but the figures don’t fib: 7.6 per cent more power and 14.2 per cent more torque.

Tipping the scales at 2615kg, the Rebel returns an impressive 120kW/tonne (versus 109kW/tonne for the V8), resulting in a 0-100km/h sprint-time of just 6.0 seconds, according to Ram (HO: 5.3s). That the Hurricane weighs nearly 60kg less than the Hemi helps.

Torque is sent to either the rear wheels in 2WD mode or all four wheels in 4WD mode via an eight-speed torque-converter auto, that Ram evocatively calls ‘TorqueFlite’ – memories of old Aussie Chrysler Valiants here.

A full-time on-demand transfer case is fitted, offering '2WD High', '4WD Auto' and '4WD High/Low' along with a locking rear differential.

As with all 1500s, there are wishbones up front and the rear axle is a coil-sprung rather than leaf-spring set-up.

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.

Ram says the Rebel returns a combined average of 10.7L/100km, which translates to about 283 grams/km of carbon dioxide emissions. That’s a small improvement over the Hemi V8’s 12.2L/100km and 325g/km figures, aided by stop/start tech. But stirring performance, rather than outright economy are the priorities here, according to Ram.

Brimming the big 98-litre fuel tank with 91 RON standard unleaded petrol should see a theoretical average range between refills of 916km.

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.

If you’re a dyed-in-the-wool Hemi V8 lover and dread the notion that a mere ‘six’ has taken its place in the Ram 1500 – and particularly in the sporty off-road Rebel we have here – then a rethink may be in order.

That’s because, in the spirit of iconic sixes of the past, including Ford Australia’s legendary Barra in the Falcon and Territory, the Ram’s Hurricane should blow any scepticism clear away.

And it’s all in the delivery.

Smooth and sophisticated, the 3.0-litre twin-turbo straight-six idles with a muted rumble at start-up, but then roars off the line with an unexpected and prolonged burst of hungry acceleration.

And the power piles on effortlessly as the revs rise, with the auto seamlessly shifting through each ratio without putting a foot wrong.

Reflecting the interior design’s overall cohesiveness, the powertrain possesses a sophistication that’s far beyond what a big American truck ought to have.

That’s in 'Normal' mode. Choosing 'Sport' ups the stakes, as it also seems to stymie the stability/traction control intervention. Throttle response is noticeably sharper and more urgent, but other than the opportunity to more-easily break traction whilst getting to licence-losing speeds slightly quicker, there seemed little sense in staying in Sport.

This is a very fast ute as it is, and also an enjoyable one to drive, with a level of nuance at odds with its excessive proportions.

Even on wet and windy back roads the Rebel feels connected and controlled at speed.

The steering is appropriately weighted, with a sufficient amount of response for the driver to push on with confidence when taking corners quickly.

Remember, this is a 2.6-tonne-plus full-sized ute on off-road-biased tyres, yet getting into a rhythm and flow with the road is easy. Yes, you feel the mass, but the 1500 also feels taut and secure. And you’re not constantly harangued by over-zealous driver-assist systems going off all the time.

The wishbone front/coil-sprung rear suspension set-up must take much of the credit here, smothering bumps and tracing the groove of the road without jolting or stepping out of line.

Comfortable and quiet, there is a sense of isolation from the outside world that, incongruously perhaps, is in league with better premium SUVs. Again, this is a big American pick-up, remember.

On a few downhill twisty bits, the driver of course feels the shift in mass, but deft handling, adequate grip (great for off-road tyres) and effective brakes mean the Rebel doesn't break a sweat, even through puddles blanketing the bitumen.

Downsides? Well, it's still a large, lumbering truck to drive and park, with an inevitably massive turning circle to make heavy work of manoeuvring this beast around. Regular car park spots are almost always too small.

There's some wind noise rustling around the large exterior mirrors. And a bit of road noise coming through over certain coarser surfaces.

Overall, though, the Rebel behaves way-better than expected – and you don’t often get a chance to say that about a ute. Rapid, refined and engaging from behind the wheel, it is the best-driving full-sized US pick-up by some margin.

What V8!

That’s on road. We also had a brief off-road stint in the Rebel at the ex-Holden proving ground at Lang Lang, and we were pretty impressed with the ability and ease demonstrated over some short but demanding rough-track sections.

We doubt – at nearly $150K – that most buyers will go bush-bashing in this, but it’s good to know the hardware is there underneath to get you through.

Neither ANCAP nor Euro NCAP have tested any full-sized American utes at this stage.

However, the Ram DT 1500 has scored a five-star result in the US National Highway Traffic Safety Administration rankings.

Keep in mind, too, that the Rebel shares the Laramie Sport and Limited’s advanced driver assist systems, ushering safety like AEB (including cyclist and pedestrian detection), 'Forward Collision Warning', rear cross-traffic alert, blind-spot monitoring, a 360-degree camera view, trailer-sway control and tyre pressure monitors.

Additionally, there are six airbags (dual front, front side and curtain), traction and stability controls and adaptive cruise control.

No speed operation data for the AEB and lane support systems are currently available.

Like all Ram DT 1500s, the Rebel includes three child-seat restraining top-tether points fitted, along with two ISOFIX latches in the rear outboard seats.

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.

Ram drops the ball when it comes to warranty.

That’s because, like GMSV’s Silverado range, it only offers a three-year, 100,000km warranty with roadside assistance, which falls short of the rival Ford F-150 and Toyota Tundra’s five-year/unlimited kilometre coverage.

In an era where Chinese rivals are rolling out utes with seven-year schemes, Ram's (and GMSV's) warranty is severely lacking.

Service intervals are at every 12 months or 12,000km, and there is currently no capped-price servicing on offer.
