BMW M2 vs Mercedes-Benz G580

What's the difference?

Proving good things still come in small packages, the pint-sized M2 remains my pick of the BMW M range. It's not the perfect daily drive, but I reckon the fun outweighs the foibles.

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 have been mixed reviews of the design of the BMW M range, but I reckon this one looks pretty damn good. In fact, I've always thought this kind of hyper-aggressive styling looks better on smaller cars than it does on big ones.

And it certainly is aggressive, right? From the huge bonnet bulges to the meshed out grille and angry rear diffuser, to the staggered alloys and flared wheel arches, to the blocky rear end with its four massive exhaust exits.

But my favourite exterior item has to be the blacked-out carbon roof, which helps shrink the M2 visually, and makes the whole car look more potent.

Inside, it's plenty sporty feeling, with hard-backed sports seats, lashings of carbon-fibre-look trimmings and the bright red M buttons on the steering wheel.

It's nice, but some of the touch points – like the hard plastics on top of the doors, where, if you're like me, you rest your elbow when driving – feel less than premium.

Still, all the tech is present and accounted for, with its digital dash and huge centre screen, and there's no shortage of spaces to connect or charge your phone.

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 M2 pocket rocket measures just over 4.5m in length, just under 1.9m in width, and just over 1.4m in height, and it rides on a 2747mm wheelbase. That makes it longer, wider and lower than the model it replaces.

Remember that 'lower' bit, as it will come up again in a moment.

Up front, you don't feel cramped, and there's the requisite cupholders, door pockets and hiding holes, as well as wireless device charging and USB connections.

But remember, this is a two-door, four-seat affair, which cuts into the practicality a little, or a lot.

Swing open the wide front doors, and push the front seat-back forwards, and the entire chair will slide forward automatically.

It does help create more room to climb into the back, but it's still a slightly embarrassing challenge to make getting back there look anything like graceful.

Once there, it's tight. I'm 175cm and my head was firmly pressed into the roof.

You do get your own vents and temp controls, but that's about it. Even the pull-down divider only gives you access to the 390-litre boot, rather than extra cupholders.

You do get two sets of ISOFIX attachment points, though, and let's be honest –  if you're buying this to make Bunnings runs, you've probably got it wrong.

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.

Besides, this is what we're really here for, isn't it? The M2 gets the 'M TwinPower' 3.0-litre twin-turbo inline-six engine, producing a sizeable 338kW and 550Nm, sending that power to the rear wheels via an eight-speed auto or six-speed manual.

BMW says this engine is very, very close to the engine that powers the M3 and M4, and says it will rocket the M2 from 0-100km/h in 4.1 seconds, and to 200km/h in either 13.5 seconds in the automatic, or 14.3 seconds in the manual.

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’.

A small fly in the ointment is fuel use, with the M2 said to use 9.7L/100km on the combined cycle. It also drinks 98 RON premium, and is home to a 52-litre fuel tank. Your theoretical driving range is around 540km.

Now, be warned, you'll be bored stiff if you drive it in the way that's required to get it that low. When we were being gentle, we were somewhere between 10.5 and 11.5 litres per hundred kilometres.

Emissions are pegged a 220g/km of C02.

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.

Let's be totally up front here: the BMW M2 isn't the most comfortable vehicle to live with. In fact, I recently climbed out of the M3 Touring, and found that to be more comfortable on broken city streets.

The M2 is fitted with adaptive suspension, but even in its most comfortable settings it can feel rough, bumpy and jarring on bad roads (of which Australia has lots), and unless you're gentle with the accelerator, it can feel a little jumpy when first taking off – a by-product of its prodigious power.

Now, let's be totally up front again: I don't care. The M2 is fun, plain and simple, and for mine, the above is a fair price to pay for something that brings so much joy.

The steering is lovely, the power immediate and the soundtrack intoxicating, and it's the kind of car that's fun no matter where, how far or how fast you drive it.

In fact, fun seems to be the very centre of the M2 proposition, which definitely doesn't take itself too seriously.

For evidence, look no further than the 'M Drift Analyser', buried in a hopelessly busy multimedia system that will have you praising the CarPlay and Android Auto gods.

It will rate your best drift out of four stars, measure it for distance, and basically give you a pat on the back for doing your best hooligan impression (not on a public road, of course).

Fun, then, is the order of the day here. And I bloody love it.

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.

The BMW M2 is covered by a five-year, unlimited kilometre warranty, and servicing is 'condition based', in that the vehicle will tell you what maintenance is required, and when.

You can prepay your service costs at the time of purchase for all BMW vehicles, covering the first five years of ownership, for $3480 (which means $695 per service).

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.
