Mercedes-Benz G580 vs Holden Spark

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.

The marvels of local engineering strike again: the Spark LT definitely feels a cut above some of its budget competition from behind the wheel. It is well-equipped, too, and packed with connectivity and technology features. In short, it could be just the spark Australia's city-car segment needs.

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.

There's only so much that can be done with a car in this bracket (there's hardly an abundance of surface metal to play with), but Holden's Korean design team have done an admirable job of inserting some excitement into what is traditionally a fairly bland category.

More youth appeal arrives courtesy of a huge array of personalisation options.

A powerful front end, with two fog lights sitting below the headlights, is dominated by a vaguely Kia-esque grille. And when viewed side on, the Spark looks to be sitting low, courtesy of standard 15-inch alloys that fill the wheel arches and tarmac-kissing side skirting that runs front to back. Two fairly heavy body creases also break up the metal monotony, running along the front and rear doors.

It's an energetic-looking package, and even more youth appeal arrives courtesy of a huge array of personalisation options, with Holden promising 33 different changes a buyer can make, including the wheel inserts, wing mirror caps and roof rails.

Inside, the focus is more on connectivity than luxury, so you can expect fake leather, hard plastics and fairly ordinary seat cushioning, but it's all nicely put together, and the basic feel is broken up by some well-placed style elements, like the coloured insert that runs the length of the dash.

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.

Nope. This is a pocket-sized car, namely because it has the same cargo capacity as your pocket.

Holden has stretched the space between the wheels to maximise passenger space, and as a result there's actually plenty of room in either row. But to add space somewhere, you need to take it from somewhere else, and that somewhere else is the boot, where you'll find a mere 185-litres of luggage space. The situation is improved by dropping the 60:40 split rear seats, but you'll be forever choosing between passengers and luggage.

Front seat passengers share a pair of cupholders, but rear seat passengers get none. They don't get room for bottles in their door pockets. Or door pockets at all, for that matter. The backseat does, however, get two ISOFIX attachment points, one in each window seat.

While the cheap and cheerful entry-level Spark, the $13,990 LS, plays smack-bang in the middle of the micro-car segment, the top-spec LT has bigger, and considerably more expensive, shoes to fill. At $18,990, the LT sails perilously close to its bigger and equally well-equipped competition.

For that money, the Spark needs to arrive wanting for little, and in most respects it does exactly that. For a start, a CVT automatic is standard, and is joined by some stand-out features in this segment, like cruise control, keyless entry with proximity unlocking, push-button start and a fake leather trim that Holden calls Sportec.

While navigation isn't standard, the Spark LT's seven-inch touchscreen is both Android Auto and Apple Car Play equipped, so phone maps fill the blank with ease.

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 just the one engine available across the Spark range, and that's a 1.4-litre petrol unit that'll generate 73kW and 128Nm.

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.

Spring for the LT, and that's paired with a CVT automatic transmission, with Holden promising that combination will sip a claimed/combined 5.5L/100km (though we recorded a less impressive 8.0 litres on our test).

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.

Holden's Aussie engineering team say they were able to get their hands all over the new Spark pre-launch, launching lap after lap of the company's proving ground as they tweaked the steering and suspension tune to better suit local conditions. And the results are very good.

The 1.4-litre engine doesn't generate a huge amount of power (though it is good for its class), but it's delivered in a way that makes the Spark feel like it's punching well above its weight, rarely feeling underpowered in everyday situations.

There is a certain skittishness to the way it drives at times.

The Aussie magic sprinkled over the suspension and steering transforms the way the Spark LT drives, both in the city and further afield. The ride nudges the firm side of the spectrum (but not enough to bother you over inner-city ruts and bumps) which translates to a low, flat feeling through corners.

All in all, the little Spark more than holds its own on more challenging roads. The steering, too, helps the Spark outshine the regular city commuters, with a naturally engaging set-up that always feels connected to the road below.

There is a certain skittishness to the way it drives at times, though, with the gearbox wanting to continue lurching forward for a split-second after you take your foot off the accelerator, which takes some getting used to.

Standard safety fare comes courtesy of six airbags, along with hill-hold assist, ABS and ESC, but it does miss out on more advanced technologies like autonomous brakes.

Springing for the LT will add rear parking sensors, a rear-view camera and cruise control as standard fare, though the lot can be added to the entry-level LS as part of Holden's Driver Assistance Pack.

The Spark range scored the maximum five-star ANCAP safety rating when tested early this year.

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.

The Spark range is covered by a three-year, 100,000km warranty and requires servicing every 15,000kms. The Spark range falls under Holden's lifetime capped price servicing scheme, with trips to the dealership capped at $1,145 total for the first five services.
