Smart 1 vs Mercedes-Benz G580

What's the difference?

It’s easy to get lost in marketing hype, but — based on first impressions — the Smart #1 does what it says on the tin. This is a Chinese-built SUV that feels more premium than most, and one which is priced to tempt you from one of the German big three. The warranty isn’t good enough, though, and the multimedia screen can be infuriating, but it drives very nicely, especially on suburban roads.

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.

There is an impossibility pretty model in Smart’s new line-up, but the #1 ain’t it. While the #3 — which has also just launched — is a sleek-looking, coupe-style SUV, the #1 is a top-heavy small SUV that doesn’t shine from every angle.

Front-on, or from a front three-quarter angle, the #1 definitely works, with the brand setting out to remove unnecessary fussiness from the design, leaving smooth and rounded bodywork in its place.

There are no body creases or weird angles here, instead it’s a smooth, fluid-like design that flows from the front LED lights bar to the smooth shoulder lines to the matching light treatment at the rear. 

But it’s at the rear where, for mine, the design begins to fall over. From that angle, the #1 looks skinny and top-heavy, especially when wearing the red hat of the Brabus model.

Still, eye of the beholder and all that.

Inside, though, the #1 kicks all sorts of goals, presenting as a properly premium-feeling EV space that’s swimming with technology and lovely cabin materials.

I particularly love the letterbox-style screen that replaces the traditional dashboard. It’s not distracting or overbearing like some twin-screen set-ups, but clearly shows you the key driving stuff you need when you’re on the road.

Side note, though, the massive central screen is super clear and lightning fast, but as usual you need to spend some (a lot) of time with it to figure out where all the functions are hiding, with most of the car’s key controls hidden within its labyrinth.

And side note two, the background graphics look like they were designed by a cordial-addled child, it is busy, cartoonish and out of keeping with the calm, grown-up nature of the #1’s cabin.

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.

The Smart #1 measures just under 4.3m long, just over 1.8m in width and around 1.6m in height, and it rides on a 2.75m wheelbase. And the perk of the Smart’s EV powertrain, the brand says, is Mercedes-Benz E-Class levels of space in the back seat, despite the #1’s diminutive footprint.

It’s a big claim, and while I didn’t break out the tape measure I can say the backseat feels plenty generous, and because the rear pew slides forwards or backwards by 15cm, you can choose whether you want more legroom or more luggage space.

Speaking of which, pop the auto-opening boot (by hitting the ‘a’ in the ‘Smart’ lettering, which I couldn’t figure out without help) and you’ll find 323 litres of space with the back seat as far back as it goes, growing to 411 litres with it pushed all the way forward. There’s also a 15-litre frunk.

Smart says the #1 weighs 1800kg, adding it will tow 1600kg — but I’m sure you can imagine the impact a heavy load will have on your driving range.

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.

There are two drivetrains on offer here - one shared across the Pro+ and Premium, and another delivering the prodigious power of the #1 Brabus.

The first shared option is a single rear motor that delivers 200kW and 343Nm, which is enough to knock off the sprint to 100km/h in 6.7 seconds. Top speed for all models is listed as 180km/h.

The Brabus, though, adds a motor at the front axle, giving it AWD, which ups the outputs to a punchy 315kW and 543Nm, dropping the sprint to 100km/h to a very fast-feeling 3.9 seconds.

It’s a single-speed EV transmission in each, which means smooth, constant power delivery with no traditional ‘steps’, and all get 'Eco', 'Normal' and 'Sport' drive modes, though the only thing they impact is the accelerator response.

You can add weight to the steering, but that’s a separate item accessed elsewhere in the screen’s sub-menus.

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’.

All Smart #1 models share the same 66kWh battery, but how far you can travel between charges comes down to the trim you choose, with the WLTP driving range either 400km, 420km or 440km. The Brabus, of course, covers the least ground between charges, owing to its dual-motor set-up and amped up power outputs. 

When it comes time to plug in, all models are equipped with 150kW DC fast-charging capability, and when plugged into said charger, you can expect to go from zero to 80 per cent charged in less than 30 minutes. 

There’s also 22kW AC charging on board in the Premium and Brabus models, which means you can use three-phase power, but plugged into a regular 7.4kWh home wallbox should see you go from zero to 80 per cent charged in 7.5 hours, which means overnight charging should work a treat.

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.

The #1 and its sister car, the #3, might share powertrains and batteries, but they are designed to drive very differently. The #3 is the sporty one (always code for a firmer ride), while the #1 is supposed to be softer, more comfortable and more city-friendly.

That’s the theory, at least. In practice, I have no idea. My time behind the wheel of the #1 was limited to its most fire-breathing model — the Brabus, which also scores its own suspension components — and soft is not a word that comes to mind once you’re strapped in behind its bright red seatbelt.

It begins with those bonkers power outputs, 315kW and 543Nm, which deliver genuine push-you-back-in-your-seat acceleration every time you stand on the go pedal.

Better still (well, I think so, at least), is that activating its sportiest 'Brabus' mode also unlocks a deep Abarth-style burbling soundtrack that rises and falls with your inputs.

But like most performance EVs, you can also dial the drive experience right back. In its softer drive modes the #1 Brabus feels calm and comfortable and not overly reactive, which makes sense, given the only thing the Brabus mode changes is accelerator sensitivity.

The result, though, is a car that you can tootle around in silently when you want to but hides a nuclear weapon under your right foot when you want to unleash that part of its personality. 

Downsides? It’s got plenty of point-and-shoot power, but in the few corners we managed to find in it, it didn’t quite live up to the all-out-performance badge. There’s a bit too much movement in the body — a symptom of its near-2.0-tonne weight — and it doesn’t feel entirely engaging.

A couple of important caveats, though. We didn’t get long behind the wheel of the #1, and the dull-as-dishwater prescribed drive program revealed little about its true performance potential. So, we’ll have to wait until the model is properly through the CarsGuide garage to give you a deeper dive on this one.

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.

Warranty is a definite soft spot, with LSH Auto offering five years or 150,000km, whichever comes first. For reference, other Chinese newcomers include Chery (seven years) BYD (six years) and GWM (seven years), while MG has just shifted to a 10-year warranty.

Still, service intervals are 12 months/20,000km, and you should be able to take your Smart to any LSH Auto Mercedes dealership (in Melbourne, Brisbane and Sydney) or either of the Smart dealerships in Sydney or Brisbane.

Service cost for the first four years averages $611 per workshop visit for the Pro+ and Premium (worth noting the fourth service is a big one) and $780 for the Brabus. Not particularly small numbers.

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.
