What's the difference?
Imagine jumping in the time machine, zapping back to the late 1970s and bringing the team that produced the original Mercedes-Benz G-Wagen into 2025 and showing them where their creation has landed close to half a century later.
They’d be amazed a vehicle looking so much like their military-focused, first-generation model even existed! And once they’d absorbed that incredible fact they’d be stunned to see what lurks under its familiar bodywork.
Because this is the most recent iteration of what’s now referred to as the G-Glass, the pure-electric G580 featuring four individually controlled electric motors - one at each wheel - collectively producing enough energy to power a small town.
Stay with us as we explore this take-no-prisoners EV 4WD that has multiple show-stopping, high-tech party tricks lurking up its sleeve.
Avan, the company, is one of Australia’s largest manufacturers of caravans and campers and the distinctly shaped Avan, the camper-trailer, is an iconic design that’s been in Australia nearly three decades.
Given that longevity, we wanted to see if there is merit in such a bizarrely shaped van, and if its claims of simple set-up really are true – and also to compare it against the Jayco Penguin, which we tested a few months back.
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 Avan isn’t for everyone, although usually when I speak to owners, they’re a passionate lot who love their campers.
I really like how easy this is to set up and pack up, and the level of comfort a solid-walled camper offers. They don’t feel very large inside, mainly thanks to the sloping roof, and that’s where something like the Jayco Penguin just wins out.
But if you can sacrifice that ‘feeling’ of space, this is a highly featured camper with a good amount of rough-road ability.
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.
Almost no-one builds an 11-foot caravan any more, and hasn’t since the 1960s, probably, but that’s essentially what the interior of the Cruiseliner is like.
Small and pokey as it is, though, it’s not impractical and not even uncomfortable. With a bed at the back, kitchen in the middle and dinette at the front, it’s got all the basic elements for comfort and because of the steep pitch of the roof, there’s plenty of headroom where it’s needed most.
It’s actually quite an efficient little space for two people, and that’s demonstrated in the storage that’s available. Almost all of it is easy to get to – except the cupboard under the table – and some of the biggest areas can be accessed from inside or out.
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 Cruiseliner Adventure Plus was great to tow. The low weight and low roof height reduces drag and it’s very stable on the road. For a little while, Avan was importing its suspension from overseas, and the system had a few teething problems. Now the Adventure Plus is fitted with Australian-made AL-KO Enduro independent coil-spring suspension, which is a very reliable and high-performing package.
Although this is the ‘off-road’ version of the Avan, the company’s ‘off-road’ policy is very conservative, and it recommends this only for gravel roads and water crossings no deeper than the bottom of the chassis.
The off-road pack does go a little further than Jayco’s Outback pack, though, as Avan includes and off-road hitch, upgraded drawer runners and wall hinges, over and above the upgraded suspension and chassis.
