Mercedes-Benz G580 vs Toyota BZ4X

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 Toyota bZ4X base variant is an uncomplicated car to drive. It has some decent features for its grade level and it is plenty big enough for my little family of three but it doesn’t always come out ahead of its rivals.

It would be an easy EV to dip your toes in if you’re wanting something economical to maintain yet able to fit the family. But it's expensive for what it is.

My seven-year old likes the cool looks but has been confused about Mummy is reviewing the same car again.

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 not much separating the bZ4X from its Subaru twin other than badging and ever-so-slightly different front and rear fascias. The differences are so small only diehard enthusiasts will be able to tell them apart. To me, they look the same on the outside!

The overall look is sporty and fun with lots of pleating in the panelling to give it a futuristic vibe and sharply defined tail-lights for some edginess.

Against our test model's 'Liquid Metal' paintwork the heavy black plastic moulding wrapping around the base of the car doesn't stand out too much but will on a lighter colour.

The internals do differ somewhat and the best change is the more traditional round steering wheel. I prefer the look and feel of it compared to the squared-off shape of its twin's.

The 7.0-inch digital instrument cluster is set a fair way back on the dashboard and looks disjointed from the rest of the tech. The steering wheel also cuts into my vision of the screen and while I could shift my seating position to better accommodate, I'd be compromising my driving comfort to do so. A head-up display would be welcome here.

The dashboard, doors and seats all feature a grey knit-like fabric that looks warm and inviting but the cabin is elevated by synthetic leather trims throughout. Overall, the cabin is quite pleasant but wouldn’t be out of place on a much more affordable car.

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 cabin is very spacious with generous leg- and headroom. I have plenty of room for my 168cm (5'6") height but my 183cm (6'0") father was also very comfortable in both rows.

The seats in both rows are well-cushioned and up front, the driver’s side has ample support from the two-way powered lumbar. I also like the way both front seats are heated. You could handle a long trip even as a passenger prince/ss.

Individual storage is less generous than you’d expect for the class given you don’t get a glove box but there are still enough nooks and cubbies for some items and a shelf underneath the console can fit a small handbag.

My seven-year old discovered a secret pocket underneath a removeable box in the middle console where Toyota has stored the manual and logbook.

Up front you also get two cupholders, four drink bottle holders (two in each door) and a handy cubby behind the rotary transmission shifter. In the rear you get map pockets, two cupholders and a device holder in the fold-down armrest and a large drink bottle holder in each door.

No complaints from my kid regarding the amenities in the back and he likes having his own directional air vents and reading lights. But it's the 182mm ground clearance we all love because the bZ4X is super easy to get in and out of. Definitely no grunts in this one!

There's no frunk storage but the boot's 421L capacity will suffice for your bigger grocery run or odd trip but the capacity is lower than some rivals. Underneath the level loading space there's a retractable cargo liner, two cable pouches, a first aid kit and the tyre puncture repair kit. I like the powered tailgate on the base model. I find them handy with a kid in tow.

Technology is well-rounded and upmarket. The 12.3-inch touchscreen multimedia system is responsive and easy to use but the customisations for internal features are a little lacking. The built-in satellite navigation is clear and there is a dedicated Toyota services app, too.

The wireless Apple CarPlay is simple to connect to and I didn't have any dropouts with calls or connections, which is great. There is also wireless connectivity for Android Auto users.

Charging options throughout the car are solid with each row getting two USB-C ports, while the front also features a USB-A port and 12-volt socket. However, there’s no wireless charging pad or V2L (vehicle-to-load) capability which might annoy over long-term use.

There are two variants for the bZ4X range, with the base model tested here being a front-wheel drive and only sporting a single motor. This entry-grade is priced from $66,000, before on-road costs, and the top AWD variant is $74,990 MSRP.

Compared to the bZ4X's single-motor rivals, this price tag positions the Toyota right in the middle for costs with the most affordable rival being the Tesla Model Y RWD for $55,900 MSRP, then the Kia EV6 Air at $72,590 MSRP.

Although very similar, Subaru is offering its base variant as a dual-motored AWD, but for price comparisons it is $69,990 MSRP.

For a base model, you get some solid features like heated front seats, built-in satellite navigation, built-in Toyota connected services app and wireless Apple CarPlay and Android Auto.

The upholstery also features synthetic leather accents rather than just plain black cloth and you get an upgraded JBL sound system.

Like its Subaru twin, only the driver's seat is powered with lumbar support but both feature those heat functions.

Other standard features include keyless entry, push-button start, dual-zone climate control, Bluetooth connectivity, a tyre puncture repair kit and digital radio.

Technology is also rounded out by the 12.3-inch touchscreen multimedia screen, 7.0-inch digital instrument cluster and four fast USB-C ports.

There are a few items missing in this variant that feature in a lot of its rivals, which reminds you this is a base model. Things like heated rear outboard seats, a heated steering wheel and a sunroof, all of which would be easy to accept if the car wasn't edging close to $70K.

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’.

The bZ4X base variant is a front-wheel drive and has a single electric motor producing 150kW/256Nm - which sounds a bit schlumpy compared to its rivals but its pick up is great and you don’t feel it's underpowered, even when you’re on the open-road.

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 official energy consumption figure is 16.9kWh/100km and I averaged 16.1kWh over a mix of urban and open-road driving. The consumption is good and on par with some of its rivals but the official driving range from the large 71.4kWh lithium-ion battery is up to 436km, which is lower than most of its rivals by a good portion.

The bZ4X has a Type 2 CCS charging port which means you can benefit from faster DC charging speeds, up to 150kW. On a 150kW DC system you can go from 0-80 per cent in around 40-minutes.

On a 7.0kW AC charger, you can go from 10-100 per cent in 9.5 hours and that drops to seven hours on an 11kW system. All the bZ4X figures are good enough to avoid the inconvenience zone but aren't as fast as some of its competitors.

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.

You don’t often notice this base model is a front-wheel drive until you accelerate too quickly from a standstill and tlose a bit of traction. Otherwise, power delivery is smooth and while you don’t get a tummy-sucking-sensation when you put your foot down the power satisfies for city and open-road driving.

The steering feels light and there's a fair bit of understeer when tackling winding roads. This made the handling a bit lacklustre at times but it’s not too intrusive in an urban environment. Just remind yourself it’s not a performance EV if you ever start thinking ‘fast and furious’ thoughts.

Ride comfort is very good and I’d attribute that to a well-cushioned suspension set-up. While you notice bumps, you’re not bothered by them, even in the back seat. The cabin is peaceful and quiet most of the time but road noise creeps up a lot at higher speeds.

Visibility is excellent and despite a few little things, like the steering, it’s an uncomplicated car to drive.

The bZ4X isn’t too hard to park because the reversing camera is relatively clear but this grade would benefit from the 360-degree view system which is available on the top-grade model. The 4690mm length, 1860mm width and 1650mm height makes it a happy-go-lucky friend in a small car park.

The bZ4X comes with some good standard safety features like a full suite of LED lights (including the DRLs), lane departure alert, lane keeping aid, traffic sign recognition, seatbelt warning, adaptive cruise control as well as a reversing camera supported by front and rear parking sensors.

Unfortunately, the base model misses out on items the top model features like blind-spot monitoring, 'Safe Exit Assist', driver attention monitoring, rear-occupant alert and rear cross-traffic alert. All of which are fairly big-ticket items and available on much more affordable Toyotas.

Still, the bZ4X achieved a maximum five-star ANCAP safety rating from testing done in 2022 and has seven airbags, including a front centre bag.

It has AEB with forward collision warning as well as car, pedestrian and cyclist detection which is operational from 5.0-80km/h (and up to 180km/h for car detection).

There are ISOFIX child-seat mounts on the rear outboard seats and three top-tether anchor points. Two child seats will fit best, though.

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 bZ4X comes with a five-year/unlimited km warranty and the battery is covered by an eight-year or up to 160,000km warranty. Both are usual terms for the class.

There is a five-year or up to 75,000km capped priced servicing plan and annual services cost just $180, which is very competitive.

Servicing intervals are more in line with a fuel-based car at every 12-months or 15,000km, whichever occurs first.
