Mercedes-Benz G-Class vs Ford F-350

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.

If you’ve got something really heavy to tow and you have the budget to do it in grand style and with minimal effort, then a Super Duty could be just what you’re looking for. Its gargantuan proportions make it impractical for daily driving in Australian city and suburban traffic, but as a heavy-duty tow vehicle, particularly for long-haul open highway work, you’ll feel like king of the road.

Vehicle supplied by Harrison F-Trucks.

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.

Needless to say, the MY18 F350 Super Duty 4x4 is a monster, even in this SWB specification. The massive 4059mm wheelbase is 839mm longer than a Ranger Wildtrak, which is also dwarfed by the Super Duty’s 6350mm overall length (961mm longer). The F-Series’ 2032mm width is 182mm wider than the Ranger, and its 2065mm height is 217mm taller. It's like a Ranger that's been fed heaps of fertiliser.

Underneath is the kind of heavy-metal hardware needed to justify a Super Duty badge. Ford claims its massive fully-boxed steel ladder-frame chassis is up to 24 times stiffer than the previous generation, along with improved corrosion resistance. The cargo tub is made from military-grade aluminium with the dual benefits of less weight and no rust. A tough spray-on cargo tub liner boosts dent and weather protection.

Live axles are used at both ends, suspended on huge leaf spring packs at the rear and softer-riding coils up front. Steering and four-wheel disc braking are both power-assisted, of course, and there’s a choice of trailer-towing hitches available.

As you would expect, cabin space for both front and rear occupants is palatial, with even tall adults feeling dwarfed by its enormous dimensions. Rear passenger leg and shoulder room even for tall adults is limousine-grade, although headroom is reduced (but still adequate) due to the lower roof lining surrounding the full-length sunroof.

The overall fit and finish of the dashboard, following Harrison’s local RHD conversion process, displays quality workmanship. However, some DNA from its Kentucky birthplace remains in the control screen’s software, which, for example, displays 911 Assist instead of 000, and a left-side driver’s seat icon for the massage control. We also noticed that the AM radio station display only moves in 10kHz increments without the ability to tune between them (too bad if you like talkback).

There’s also no driver’s left footrest and the parking brake pedal seems overly high, requiring the raising of your left knee above steering-wheel height to get your boot on it.

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.

Our F-350 test vehicle with its F-250 downgrade results in a 700kg decrease in both payload and tow ratings. In other words, based on Harrison’s figures, in full F-350 specification it has a 1700kg payload capacity and 9700kg GCM, which means it can legally tow up to 4510kg of braked trailer with a full payload or up to 6210kg without. In our F-250 form it offers a 1000kg payload with 9000kg GCM, and can legally tow up to 3810kg of braked trailer with a full payload, or 4810kg without.

The huge cargo tub has a load floor length of 2080mm and width of 1700mm, with 1283mm between the wheel arches allowing ample room for a standard 1160mm-square Aussie pallet. There’s a total of eight tie-down points, overhead and internal lighting plus key fob operation of the tailgate, which houses a handy fold-out step and grab handle for easy cargo tub access.

The sumptuous cabin has plenty of storage options, including a single glovebox, and a bottle holder and two storage bins in each front door. The centre console has an open storage cubby at the front, another open storage bin and two bottle holders in the centre, a cavernous box behind that with a padded lid which doubles as a comfortable armrest, and two more bottle/cup holders at the back.

Those in the rear seat also get a fold-down centre armrest with two pop-out cup holders and each rear door has a bottle holder and two storage bins. There are also flexible storage pockets on the rear of both front seats and the 60/40-split rear seat base cushions swing up through 90 degrees and lock into position, revealing a huge full-width storage area underneath.

Our test vehicle was the MY18 F350 SWB Crew Cab Platinum 4x4 pick-up, downrated to a 4490kg GVM rating (same as the F-250) to allow it to be driven with a normal car licence. According to Harrison, Ford achieves this by simply removing an additional booster spring and block in the rear suspension, resulting in the lower ratings. It was also fitted with Ford’s FX4 off-road option (rear diff lock, skid plates, special shocks, hill-descent control), bringing the drive-away price to an eye-watering $165,990.

The Platinum is one of six grades in the Super Duty range, and one of three only available in the Crew Cab, in which it represents the middle tier above King Ranch and below Limited. Although Harrison can import most of the Super Duty model grades, it claims the Platinum delivers the best ‘bang for buck’ in terms of features and trim level, riding on stylish 20-inch polished alloy wheels and LT245/75Rx17E all-terrain tyres with a full-size spare.

As you can imagine, the sumptuous Platinum has power everything and is loaded with features that are way too numerous to list here. Suffice to say, everywhere you look there’s conspicuous luxury, from the moment the concealed power-operated side-steps smoothly extend when you open the door, and then retract when you close it.

Inside is an 8.0-inch touchscreen for the SYNC3 voice-activated infotainment system with multiple connectivity options, including Apple CarPlay and Android Auto, premium leather seating (with heating, cooling and even massage for the front seats), a full-length panoramic sunroof, huge power-extendable door mirrors for towing (with built-in courtesy lights), power adjustable pedals and steering wheel (which is also heated), remote-opening tailgate with fold-out step, cameras everywhere for 360-degree coverage and even a wide choice of changeable colours for the ambient cabin lighting.

We could go on, but you get the picture. It’s magnificent excess in the true US tradition, where too much is never enough.

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 F350 Super Duty is powered by Ford’s common rail 6.7-litre Power Stroke V8 turbo diesel, which, with four valves per cylinder and variable vane turbocharger, punches out 335kW at 2800rpm and a massive 1267Nm of torque at only 1800rpm.

The SelectShift six-speed automatic transmission is also designed and built by Ford. Its triple-plate, two-stage torque converter offers full lock-up capability as low as 900rpm, and there’s a dedicated tow/haul mode which avoids unwanted shifts on climbs and provides powerful engine braking on descents.

The exhaust brake can also be manually selected. The 4x4 system is part-time dual-range, with auto-locking front hubs and shift-on-the-fly engagement.

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.

Flick through a Super Duty sales brochure and you won’t find any reference to fuel economy ratings. However, for what it’s worth we crunched some figures at the end of our relatively short 200km test based on trip meter and fuel bowser readings, resulting in a reasonable 15.8L/100km.

That’s not far away from the dash read-out at 14.2, so with its big 130-litre fuel tank you could expect a driving range of around 820km.

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.

You sit up nice and high in very comfortable seats, with a commanding view of surrounding traffic and the road ahead. We quickly adapted to the width and height of the Super Duty, but the major issue in city and suburban driving was its oil-tanker length, which required later turn-in on tight corners to provide kerbside clearance. We also needed to check that there was ample reversing room when choosing a space in a parking lot, to ensure we didn’t get wedged when trying to leave.

With the big turbo diesel V8’s 1267Nm of torque being tapped at only 1800rpm, it provides spirited getaways from traffic lights, and easily keeps up with normal city and suburban traffic flow with your big toe barely touching the accelerator pedal.

The ride quality without a load is quite good on smooth surfaces, with its massive 3.5 tonne kerb weight feeling like the tyres are leaving indents in the bitumen. However, over rougher roads and larger obstacles like speeds humps, it starts to bounce around more and can feel quite ponderous at times. However, this is to be expected in an empty vehicle with such high payload and tow ratings.

The steering is surprisingly direct and firm in feel. It’s also quite linear in turning weight regardless of road speed, without the more noticeable changes evident in its little brother Ranger, which is very light at parking speeds but gets noticeably firmer as speeds increase.

Braking is reasonably responsive but like other giant US pick-ups we’ve tested, you have to get them quite hot to make them really bite. That’s because their pad compounds tend to be on the hard side, given they have to cope with the high temperatures generated by heavy-duty towing.

The engine exhaust brake is surprisingly quiet and very effective at slowing the vehicle, aided by more aggressive downshifts in the six-speed auto.

No ANCAP rating, but for what it’s worth the 2017 F-250 Super Duty SuperCab and Crew Cab 4x2 models earned the US government’s highest five-star safety rating. Passive safety includes driver and passenger front and seat-side airbags plus side-curtain airbags. All three rear seat positions have top tethers for child seat restraints but no ISOFIX.

Dynamic safety does not include AEB, but there’s adaptive cruise control and collision warning with brake support, (BLIS) blind spot information system with trailer coverage and cross-traffic alert, lane-keeping alert, reverse sensing system, rain-sensing wipers, automatic high beam headlights, hill-start assist, trailer sway control, tyre-pressure monitoring, SOS post-crash alert system and lots more.

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.

Harrison F Trucks provides a four-year/130,000km warranty, which it claims is the same as the Ford warranty with standard exclusions. Harrison also provides four-year premium roadside assistance.

Scheduled servicing is 12 months/10,000km with costs ranging between $495 and $1400.

Harrison says servicing can be done at any certified service department in Australia, with direct communication with Harrison’s service manager if required for diagnostics and advice.
