Mazda CX-8 vs Mercedes-Benz G-Class

What's the difference?

So, what did my family think about the Mazda CX-8 GT SP diesel all-wheel drive? I love how it performs on the road - it's super easy to drive and you don't notice how large it is in a car park.

There are some great family-friendly features scattered throughout and I like how practical this is too with the extra seats and top-tether points. The multimedia system isn’t my favourite and I would have preferred to have seen a few extra airbags and a 360-degree view camera, but overall, it’s a good family car and gets an 8.0/10 from me. 

My son loved the sun blinds and the cool colour of the seats. He also gives it an 8.0/10.

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.

To be honest, I can't really tell the CX-8 and CX-9 apart on the road. They're both large SUVs that sport the classic Mazda bonnet - sharp and long. Up close, the CX-9 has a bulkier shape but otherwise they are remarkably similar.

The CX-8's darkened grille generates some interest with its lattice-work and there are enough shiny chrome accents scattered about the car that it looks pretty.

Yet, the sporty sharpness that Mazda is known for is still hinted at with its shaping and the 19-inch black alloy wheels.

Our model is finished in 'Platinum Quartz Metallic' and it is the highlight for the exterior styling for me. I think because it's such an interesting colour to look at - it varies a lot depending on lighting conditions. Sometimes, it almost has a sheen of pink to it and at others, it looks like pearly sand.

The interior looks polished and refined with its burgundy leather trim and soft-touchpoints. Again, there is a lot of chrome inside to make otherwise dull features, like air vents, pop out.

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 CX-8 is a very practical family hauler because there's ample room in all three rows. Yes, even adults will be able to squeeze into that third row without too many complaints!

All rows enjoy well-cushioned seats and up front they are electrically adjustable, but unfortunately, only the driver's side has lumbar support.

The middle row can slide forward manually or by using the electric button found on the side of the seats... but doing it yourself is way faster.

They do slide far enough forward that you won't embarrass yourself too much when you have to clamber into the third row. Where the seats have a 50/50 split-fold and manual adjustments (accessed via the boot).

In the first two rows there are lots of individual storage options but the front enjoys the most. The middle console is deep enough to be useful and I like the dual opening lid. Each row gets a couple of cupholders and drink bottle holders, too.

The charging options are great, with each row getting two USB-C ports and the front getting a wireless charging pad and 12-volt socket.

All of the controls and dials feel within easy reach and the 10.25-inch touchscreen multimedia system graphics are clear.

You can use it as a touchscreen or opt for the rotary dial but switching between the two was awkward for me. Especially, since the touchscreen function is disabled when you are using the wireless Apple CarPlay. This also has wired Android Auto, for those users. 

The amenities are practical throughout with a dark headliner, three-zone climate control and heated outboard seats and retractable sun-blinds in the middle row.

Good news for families because there are five top-tether points across the back rows and ISOFIX child seat mounts on the outboard seats in middle row, in case you need them.

You can fit a 0-4 rearward facing child seat and it shouldn’t impact on front passenger comfort. 

My six-year old found it super easy to get in and out of this car because of the 205mm ground clearance and wide door apertures. He enjoyed the high seating position, too, but was disappointed he couldn’t see out of the sunroof!

The boot space is a bit cramped with all three rows are in use at 209L but folding the third row opens up a more respectable 775L - perfect for the average family and its stuff!

The loading space is level, with the temporary spare tyre and clever storage compartments housed underneath. There is a retractable cargo blind and net, luggage anchor points and a 12-volt port, too. 

And, as always, I love a powered tailgate, which this has!

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.
