Porsche Macan vs Mercedes-Benz G-Class

What's the difference?

There is no doubting the substance of the Porsche Macan Electric. Its ride, steering and poise make it a joy to drive on twisting roads, and it ticks the practicality boxes, too.

The only lingering question is whether enough people are ready to make the all-electric switch. Only then will we know if Porsche's Macan gamble has paid off.

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 Macan Electric looks sharp, all aerodynamic and swept-back like a range-maximising electric SUV should.

There’s functional method behind all this swoopy styling, too. The headlights look as though they’ve been chiselled into the body work, and at the grille, you’ll find active venting to help with cooling when needed.

There is also a sizeable front splitter that looks very much like the Macan is sticking its jaw out. All of which is to assist with aero and range.

It’s also a dual charging port layout with access left and right, though the latter is AC charging only, while the one on the left does both.

Step inside the Macan and you’ll find a familiar and very welcoming space. I especially like the twin-screen set-up that looks great in the way it's kind of embedded into the dash. Each is big, clear and easy to use.

I also really like the control panel that gives you quick-button access to the climate control, and the haptic feedback is next level, with the whole screen clicking in or out whenever you hit a button.

That said, in Turbo-guise you’re dropping almost $200,000, and some of the materials feel too hard and plasticky at that price point.

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 is a little open-sesame magic at play with the Macan, and that starts at the frunk, where, if you lovingly caress the bonnet, it will automatically pop open for you, revealing an 84-litre storage space.

Rubbing the charging port will see it slide open, too, but just in case you’re not the kind of person who likes to fondle their car in public, you can use the key.

The Macan’s boot is a little more traditional, opening to reveal 540 litres (but just 480 litres in the 4S or Turbo) of storage with the rear seats in place, with a wide, flat and very useable area for your goodies.

The back seat of the Macan feels spacious enough, without being outstanding. There’s more than enough space for my 175cm frame, with enough knee and head room, but the way the middle console juts out will definitely eat into leg room for any middle-row passenger.

Elsewhere you get air-con controls with vents, along with bottle storage in each of the doors. There is also a pull-down divider that’s home to two extra cupholders.

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.

The entry-level Macan is equipped with a single rear-mounted electric motor, and it will make a total 250kW (265kW with launch control activated) and 563Nm, which is enough to push the cheapest Macan to 100km/h in 5.7 seconds.

The 4 then adds a second electric motor for AWD, upping the grunt to 285kW (300kW with the launch function) and 650Nm, and drops the sprint to a brisk 5.2 seconds.

The 4S is probably the performance sweet spot, with its dual-motor set-up generating 330kW (380kW in launch) and 820Nm, and a blistering sprint of just 4.1 seconds.

But the Macan Turbo is a true monster. We’re talking 430kW (470kW with launch control), 1130Nm and a sprint to 100km/h that’s as fast as a Carrera Cup race car – just 3.3 seconds.

It’s twin-motor, all-wheel drive and offers the kind of brutal acceleration that gives you a little facelift every time you step on the accelerator.

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’.

Every Macan is fitted with a big 100kWh lithium-ion battery, which helps deliver a solid driving range no matter which one you choose.

The entry-level Macan will cover the most distance, at a claimed 654km, while the 4, 4S and Turbo will travel 624km, 619km and 616km, respectively.

The Macan rides on an 800V architecture, and is set up for 270kW DC high-speed charging, which will take 21min to go from 10 to 80 per cent. It will also accept 11kW AC charging, which should take 10 hours to go from empty to full.

Worth noting, though, that most home wall boxes are around 7.0kW, which means a full charge would take more like 13 hours plus.

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.

Porsche seemed at pains to prove that, though the all-electric Macan has lost its ICE heart, it's still worthy of the badge, and still very much a Porsche.

First stop, then, was the Norwell race circuit in Queensland, to put the Macan through its paces with 0-100km/h sprints, drifting (well drift attempts... ) on a watered-down skid pan and finally some high-speed running on the circuit.

And two things immediately became very clear. The first, and most obvious, was that, like the first men on the moon, we were likely among only a handful of people that might ever take their all-electric Porsche mid-size SUV to a race track. And second, this is one seriously sorted electric car.

Happily, for the many (read: every) owners who won't be pulling out of a pit garage at their next local track day, the Macan is actually more enjoyable on the road than it is on the track.

On the latter, there's a freedom to push too hard – what with the lack of trees, guard rails or oncoming traffic – and cracks do appear, mostly from the screaming tyres struggling with the two-tonne-plus weight.

But on public roads, where a thick fog of consequence prevents you pushing too hard, the Macan is a gem.

Porsche tends to have a knack for these things, I know, but the Macan is a seriously smooth and satisfying drive.

The ride is bang-on (comfortable enough on rougher surfaces, firm and grippy enough on twisting roads) and the steering is direct and confidence-inspiring.

Body-roll has been largely banished, too, with the Macan staying flat, stable and satisfying, even on the tighter stuff.

In much the same way the ICE Macan defined what it meant to be a driver's SUV, I think this one does the same in the EV space. And the fact that it does it with five seats and a decent boot is a sizeable bonus.

But there's no denying it lacks in the emotion department. That sense of excitement, the sound track, the hard-to-define fizz – as competent its this, and as weaponised as the EV powertrain is – it does feel a little clinical, like a tool doing its job and doing it well.

One important caveat. We've driven the 4 and Turbo to date. The entry-level Macan and the mid-tier 4S are still incoming. And I suspect I wouldn't be dropping my deposit on the Turbo.

Yes, the power is ridiculous, but I don't reckon you need it. For me, the 4 is more than enough, but I suspect the real performance sweet spot will be with the 4S.

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 Porsche ownership experience is frankly underwhelming by modern standards, with the brand offering just a three-year/unlimited kilometre warranty, plus an eight-year/160,000km battery warranty.

The positive, though, is that servicing should only be required every two years or 30,000km. You also buy a prepaid service plan for three, four or five years, priced at $1495, $2795, $2995.

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.
