Mercedes-Benz G63 vs Renault Duster

What's the difference?

The Mercedes-AMG G 63 isn't for shrinking violets. It's bold, fast, and loud, and in second-generation form massively improved dynamically and technically. It's a lot of money, but there's a lot to love, and here's hoping it stays around for decades to come.

The Renault Duster looks set to put the French carmaker back on the map here in Australia.

While there will likely be general appeal thanks to its cool looks, it holds special appeal for us off-road enthusiasts as a new, cost-affective option that’s filled to the brim with character and charisma.

While it may not be perfect, it also doesn’t matter. In fact, this makes me like the Duster even more.

The manual AWD feels like the purest and most correct way to experience the Duster as it’s so smile-inducing. However, this isn’t to discredit the automatic FWD version as it’s arguably more liveable day-to-day.

Pick your poison. You’re bound to love it no matter which way you go.

Note: CarsGuide attended this event as a guest of the manufacturer, with accommodation and meals provided.

The original (W460) G-Glass, then known as the G-Wagen (or Geländewagen for cross-country vehicle), was launched in 1979 as an ultra-capable off-roader, soon favoured by armies the world over. Arriving here in 1982, its distinctive, slab-sided form remained unchanged over the best part of four decades.

At close to 4.8m nose-to-tail, more than 1.8m across, and a bit over 1.9m tall, the G 63 is now longer (+110mm), wider (+106mm), and fractionally lower overall (-13mm), but still pulls off a convincing impersonation of a bread box.

Merc-AMG confidently quotes a drag coefficient (Cd) of 0.55 for the G 63, which isn't as bad as a brick (around 2.0… I Googled it) although it is in the same league as a heavy truck.

But it's the car's unique, upright stance, complete with pumped wheelarches and old-school flat glass, that sets it apart and draws people in. Looking more like a take-no-prisoners, functional device than a luxury cruiser, I can assure you it attracts as many admiring looks and comments as a low-flying supercar wedge.

The new-gen G 63 features AMG's vertically slatted 'Panamericana' grille, and our test example was fitted with the optional 'Night Package' ($5900) adding a range of dark exterior details including tinted indicator lenses, dark tinted glass, black exterior mirror shells and spare wheel ring, other black trim pieces and painted areas, as well as 22-inch AMG forged alloy rims.

Also worth noting, Merc has retained the G-Class's solid metal door handles, complete with the mechanism's unmistakable 'click-clack' opening and closing sound. Nice touch.

Inside, the biggest change is the upgrade from a conventional dual-gauge instrument cluster and central media stack to a pair of 12.3-inch digital screens, forming a sleek widescreen display, and bringing the G 63 in line with other recent Merc offerings.

Similarly, the gearshift moves from a traditional console-mounted set-up to Merc's 'Direct Select' lever on the steering column (exactly where the indicator stalk is located in 90 per cent of right-hand drive cars).  And the standard flat-bottom, leather-trimmed 'AMG Performance' steering wheel is a racy addition.

Like the exterior door handles, another tip of the hat to the car's heritage is retention of the horizontal grab handle ahead of the front passenger on the dash above the glove box. Nice to have something to hold on to if the going gets rough.

When you see a Renault Duster parked up or on the road, you’ll instantly be able to tell what it is.

This small SUV is essentially a rebadged Dacia for international markets and the design changes are minimal.

The most noticeable departure is the front grille has ‘Renault’ badging written out instead of a Dacia badge. It’s a departure from any other current Renault model on offer locally and gives the car a tough, unique presence.

There are also Y-shaped LED daytime running lights that look cool and modern.

Depending on the Duster version you opt for, the lower section of the front bumper looks different. All-wheel drive (AWD) versions sit higher to improve the approach angle and ground clearance.

Around the side there’s plenty of plastic cladding to drive home that this is a tough all-terrain machine and not your everyday crossover. I prefer it to the glossy and chrome accents on rival SUVs as it's no-nonsense.

The black body cladding around the wheel arches and along the door sills is recycled and has a fleck throughout it. There’s also a recycled icon near the side mirrors which is a touch too on the nose for my liking.

Towards the rear there are angular haunches that make the Duster look tough, as well as hidden rear door handles on the C-pillar.

At the back there are even more angles that make the Duster stand out. The most obvious is the triangular tail-lights which look funky and cool.

There’s little else to note about the rear design besides a subtle Renault badge and Duster written out on the bottom of the tailgate. I appreciate how clean the rear is because some carmakers can go over the top with badging.

Inside, the Duster defies its budget roots with a high-tech and modern-presenting design. The Y-shaped air vents continue the motif from the headlights, while the 10.1-inch touchscreen multimedia system is mounted prominently on the dash and is smartly tilted towards the driver.

After spending some time behind the wheel, however, you start to notice a lot of the Duster’s finishes inside are hard, scratchy plastics. It’s most noticeable on the dashboard.

Depending on which version you opt for, the door armrests are also finished in hard plastic. The top-spec Techno gets a softer padding on top, however.

While there is a lot of hard plastics, it’s nowhere near as noticeable as a Suzuki Jimny.

The G-Class has never been a particularly squeezy proposition for passengers or cargo, but an extra 40mm in the wheelbase adds even more breathing space.

Getting in is the first step, and it's a big one. At 183cm tall, in an athletic mood, I could grab the A-pillar and swing up into the driver's seat in one vaguely respectable movement.

But, those side steps aren't just for show, and at the end of a long day provide a handy staging camp between terra firma and the lofty pilot's chair.

Once on-board there's plenty of room up front, with adequate storage including a bin between the seats (now with a double door opening rather than a single hinged lid), a modest glove box, oddments space and two cupholders in the centre console, and bins with space for bottles in the doors.

There's a 12-volt power outlet in the front, second row and cargo area, while there are two USB ports in the centre console bin and a charging USB port in the second row.

In the back I could have donned a dusty Akubra and still had headroom to spare, with generous foot room, and a substantial gap between my knees and the driver's seat (set to my position).

A fold-down armrest incorporates a pair of cupholders (as well as a through-port to the cargo space for long items) and there are map pockets on the front seat backs as well as space for bottles in the doors. Two adjustable air vents in the rear of the front centre console, and another pair in the B-pillars also provide climate-controlled air to those in the rear.

With the rear seats upright boot volume is quoted at 454 litres (VDA); enough to easily swallow our three-piece hard suitcase set (35, 68 and 105 litres) or the CarsGuide pram, or a largest-suitcase-and-pram combo.

There are tie-down shackles in each corner of the floor, usefully bright lighting, a netted storage area on the passenger side (containing five fluorescent emergency vests), and folding the 60/40 split rear seat liberates even more space.

Unfortunately, gaining access to that load space is fraught with compromise. First, the single-piece rear door hinges vertically and opens from right to left. No problem when you've nosed into a shopping centre space, but not so great when you're parking nose-to-tail on the left-hand side of the road.

That means you typically have a small space between you and the car behind to get the door open, and when it is at 90 degrees, you're blocked from unloading things onto the footpath until you've shut the door.

As well as that, the door has a full-size spare (alloy) wheel and tyre attached to it. Good because a full-size spare is welcome, and bad because it makes the already bulky door even heavier.

Those keen on towing things will be pleased to hear the G 63 is rated to haul up to 3.5 tonnes of braked trailer and 750kg unbraked.

In terms of practicality, this is one small SUV that punches above its weight.

Up front both the seats are manually adjustable, which is expected at this price point. There’s nothing wrong with this as they still allow you to find your desired seating position.

The entry-level Evolution comes with cloth upholstery which feels nice to touch and allows for decent breathability, whereas the top-spec Techno has a premium textile that almost feels like neoprene (wetsuit material). I’m thankful there’s no leather upholstery option in this car because it wouldn’t suit its character.

Ahead of the driver is a leather-wrapped steering wheel which feels more premium than you’d expect. It feels lovely in the hand and is complimented by the squared-off shape.

Another reason why I like this steering wheel is it offers a generous amount of tilt and reach adjustment. This means people of all different sizes and statures will be able to find a comfortable driving position.

There’s a nice smattering of physical buttons on the steering wheel for critical things like the cruise control and changing the content on the digital instrument cluster, though if you want to change the volume or track, you need to interact with the stubby stalk behind the steering wheel.

This is a classic Renault quirk that’s been in a number of its cars for years. It takes a bit to get your head around, but once you do it’s second nature.

Behind the steering wheel is a 7.0-inch digital instrument cluster which looks a little small in its housing. Clear analogue dials for the rev counter and speedometer would have been better and likely more timeless.

As standard, however, there’s a big digital speedometer readout that’s easy to read, as well as a few layout styles and informative pages to cycle through.

I wish the digital rev counter was featured on more of the page layouts and it also had more numbers denoting the rev counter markings, rather than simple lines. This is particularly annoying in the manual.

Moving across, the 10.1-inch touchscreen multimedia system is clear and bright. It also helps that the native interface is simple and easy to navigate.

There’s wireless Apple CarPlay and Android Auto across the line-up which is fantastic to see and almost expected now. Complimenting this is a standard wireless phone charger at the base of the centre tunnel.

Additionally, if you opt for the Techno, you get a phone mount on the dashboard. I still haven’t decided whether this is helpful or not given there’s already wireless phone mirroring and the phone mount doesn’t provide charge as standard.

Unlike many newer cars, the Duster retains plenty of physical switchgear up front so key functions like the dual-zone climate control and drive modes.

In terms of storage up front there are two cupholders, a handy shelf for stowing things above the wireless charger, a big centre console box, as well as a deep glove box.

Moving to the second row there’s plenty of headroom, though legroom is minimal for adults above (183cm) six feet. You have to remember this is a small SUV so it’s actually not too bad.

The second-row bench seat is laid back, allowing you to get comfortable on longer drives. Two adults can easily fit back there, though pushing it to three would make it squishy.

Second-row amenities include air vents and two USB-C ports. There’s also a special connector on the back of the centre console which allows you to fit a wide range of optional 'YouClip' accessories. These include a cupholder, light or hook.

In the same vein, you can also add a phone or tablet holder to the back of the front-seat headrest. The configurability is to your heart’s content.

A downside of the second row, however, is there’s no fold-down centre armrest. This also means there are no rear cupholders as standard, which is disappointing.

At the back the entire Duster line-up has a manual tailgate, which is fine for the price point.

The boot space itself is decent as there’s no load lip, but if you’re wanting a larger space overall, it’s best to opt for the front-wheel drive (FWD) versions as they have 472L with the rear seats upright. AWD versions, on the other hand, have 358L with the rear seats up.

The Techno 4x2 in particular has a two-tier floor which allows you to stow things underneath the main boot floor, or you can create a partition to stop things moving around.

Boot-related amenities include a light, hooks and a 12V socket. There are also extra YouClip points, including one on the tailgate. This allows you to add extra lights or hooks.

As standard, all Duster variants get a full-size spare wheel, which is fantastic given this type of vehicle may be spending a lot of time out on the open road.

In Australia the 2026 Renault Duster is being offered in two trim levels with two powertrain options.

Pricing starts at $31,990, before on-road costs, for the Duster Evolution 4x2 automatic and extends to $37,990, before on-roads, for the Duster Techno 4x4 manual.

This is competitive pricing for the small SUV segment, especially when you consider the rugged and considerably smaller Suzuki Jimny costs similar.

As standard the Duster Evolution comes with 17-inch alloy wheels, a 7.0-inch digital instrument cluster, a 10.1-inch touchscreen multimedia system with wireless Apple CarPlay and Android Auto, a wireless charger, dual-zone climate control, an electric park brake, as well as black and grey cloth upholstery.

Stepping up to the Techno gets you larger 18-inch alloy wheels, front fog lights, privacy glass, modular roof rails, keyless entry and walk-away locking, push-button start, a smartphone holder, as well as black and grey premium textile upholstery.

While the entire Duster line-up has LED low-beam headlights, the high-beams are only halogen, which is a disappointing cost-cutting move.

Despite this, there’s still plenty of standard equipment, even from the base Evolution trim.

If that’s not enough, however, you can further personalise your Duster with a wide range of optional accessories. There are clip-on cupholders, lights, hooks and tablet holders inside, as well as Rhino Rack and Thule accessories outside.

The G 63's 4.0-litre (M177) all-alloy V8 is closed deck design using direct-injection and a pair of twin-scroll turbos to produce 430kW at 6000rpm and no less than 850Nm from 2500-3500rpm. That's 10kW/90Nm more than the 5.5-litre twin-turbo V8 it replaces!

To improve throttle response and optimise efficiency, the turbos are located inside the engine's 'V', improving air flow and shortening the distance from the exhaust side to the turbos, and in turn, from the turbos to the inlet side.

And the housings on the twin-scroll turbos are divided into two parallel flow channels connecting with separate ducts in the exhaust manifold, allowing fine management of the exhaust gas coming in and pressure going out. Result is more torque and even better response times.

Drive goes to all four wheels via a new 'AMG Speedshift' nine-speed, dual-clutch auto (replacing the previous seven-speed auto transmission) with paddle shifters and a multiple downshift function which will go to the lowest ratio possible as you keep squeezing the shift paddle.

The 'AMG Performance 4Matic' all wheel drive system is front/rear biased 40/60 (50/50 in the previous model), although if you want to head off-highway the G 63 still features three 100 per cent diff locks and low-range off-road gear reduction.

As noted earlier, the Renault Duster is offered with two different powertrains.

The most affordable option is a 1.3-litre four-cylinder turbo-petrol engine which produces 113kW of power and 270Nm of torque.

This is mated to a seven-speed dual-clutch automatic transmission with drive sent to the front wheels only. It’s worth noting this is the same powertrain that propels the Renault Arkana and Captur, as well as certain entry-level Mercedes-Benz models.

Renault claims this version of the Duster can do the 0-100km/h sprint in 9.2 seconds.

The second powertrain option is a 1.2-litre three-cylinder turbo-petrol with 48V mild-hybrid assistance which produces 96kW and 230Nm.

This is less powerful than the four-cylinder petrol but it’s mated to a six-speed manual gearbox with drive sent through an all-wheel drive system.

Renault claims the AWD Duster can do the 0-100km/h sprint in 11 seconds. That’s not very fast at all…

Claimed top speed for the entire Duster line-up in Australia is 200km/h.

Unfortunately there’s no automatic AWD Duster available globally yet so if you want to maximise your all-terrain capability, you’ll need to opt for this mild-hybrid manual powertrain option.

All versions of the Renault Duster have a braked towing capacity of 1500kg, though it’s worth noting the towball download limit is only 75kg. This could prove to be a hassle if you’ve got a towball-mounted bike rack and you put a hefty e-bike on it as this could easily send it over this threshold.

Claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle is 13.1L/100km, with the 4.0-litre, twin-turbo V8 emitting 299g/km of CO2 in the process.

Despite the fact cylinder management tech means the engine will run on four cylinders under light load, and start-stop (with 'glide mode') is standard, we managed 16.7L/100km (measured at the bowser) over a mix of city, suburban and freeway running. To be expected for such a big bus, especially one that constantly tempts you into squeezing the throttle just to hear the exhaust bellow.

Minimum fuel requirement is 98 RON premium unleaded, and you'll need 100 litres of it to fill the tank.

Renault claims the four-cylinder, FWD Duster consumes 6.5L/100km, whereas the three-cylinder, AWD is claimed to consume 5.7L/100km, both on the combined (urban/extra-urban) cycle (ADR 81/02).

The former has a 50L fuel tank and requires a minimum of 91 RON regular unleaded petrol, while the latter has a slightly larger 55L fuel tank but requires higher quality 95 RON premium unleaded petrol.

We didn’t get a chance to properly get as-tested fuel consumption figures during this initial first drive, but the FWD Duster has a theoretical range of 770km and the AWD Duster extends that to 965km.

Let's cut to the chase. The G 63's pure grunt overpowers its challenging aero profile to thrust this boom box on wheels from 0-100km/h in a claimed 4.5 seconds. And believe it or not, despite its greater length and width, it has enough power to punch a 240km/h hole in the air (maximum velocity is limited to 220km/h if you choose not to opt for the 'AMG Driver's Package').

The new electronic architecture brings with it the latest version of Merc's 'Dynamic Select' system with five driving modes adjusting the engine, transmission, suspension, steering and assistance systems right up to maximum attack Sport+ mode.

All 850Nm of peak torque is available between 2500-3500rpm and pinning the throttle anywhere in that band feels like lining up a runway and preparing to rotate for take-off.

The two-stage exhaust flap arrangement allows you to turn the noise up from growl to roar even at modest around town speeds, and the nine-speed transmission is sharp and positive, with the multiple downshift function (in manual mode) hilariously good fun.

The racy AMG sports seats are as grippy as they are comfortable, and the fat 295/40 Goodyear Eagle F1 rubber, wrapped around the optional 22-inch forged alloys, does a good job of keeping all that mass and momentum in control as the high riding G 63 careens around corners.

And speaking of mass, the job of hauling it from warp speed to rest sits with big ventilated discs all around (cross-drilled 400mm front/370mm rear), clamped by monster six piston calipers at the front and single piston at the back. They're progressive and reassuringly powerful.

So, the performance is as dramatic as ever, but when I think of previous Merc-AMG G-Class offerings, two main shortcomings come to mind... steering and ride.

The steering was like a laggy mouse, with a few beats separating input at the wheel from response at the front treads. And the damping came up short, with a bouncy ride par for the course.

Still sitting on a ladder-type frame, the new G's suspension was developed by Mercedes-Benz and Mercedes-AMG. And finally, it has a decent double-wishbone independent front-end, with a rigid axle at the rear and coil springs all around. Plus, a strut tower brace, Merc-AMG calls it a 'suspension bridge', now connects the front strut towers, increasing torsional rigidity.

Ride comfort, especially in the most compliant 'Ride Control' suspension setting and riding on the big 22s, is massively better. It's no limo. You'll still feel jittering over higher frequency imperfections. But it's way, way ahead of the first-gen version.

The steering system changes from a recirculating ball to rack and pinion, and is now variable ratio with electro-mechanical rather than purely hydraulic assistance. And it's also much improved. We're not talking about a Lotus Elise-style connection with the road, but the steering is clearly more predictable and responsive.

One thing that hasn't changed is an ocean liner-worthy, 13.6m turning circle. You'll need to plan ahead for U-turns and reverse parks, but enough parking cameras (including surround view) to please Cecil B DeMille are on hand to help.

It's like a whole new world with a familiar cover wrapped around a markedly improved package. But (there must be a but) visibility is still compromised by thick window and door pillars, and despite the new dash layout ergonomic efficiency is patchy, with some switches and knobs located in relatively awkward positions.

As mentioned earlier the G 63 features three 100 per cent diff locks and low-range off-road gear reduction. But forget breakover angles and wading depths. This 4x4 seeing off-road action is as likely as an Abbott 2.0 prime ministership.

Suffice it to say, this car wears the 'Schöckl' badge at the base of its B-pillar. And in case you were wondering, Schöckl is a 1445m mountain in Graz, the Austrian city where the G-Class is built (and big Arnie Schwarzenegger was born!).

In the second-gen G-Class's development, prototypes covered roughly 2000km over a five kay trail including gradients of up to 60 per cent and lateral inclines up to 40 per cent. So, despite its irrelevance, the off-highway box is ticked.

Depending on which version of the Duster you opt for, they’re rather different beasts. The most ‘normal’ version is the FWD auto.

This powertrain combination with the 1.3-litre turbo four-cylinder and seven-speed dual-clutch automatic immediately feels familiar if you’ve driven a current Arkana or Captur.

There’s enough power underfoot to get moving along briskly, though you won’t be breaking the land speed record anytime soon. There’s also a wealth of torque allowing the engine to feel like it’s not working hard.

It’s fun to listen to the turbo spool up during moderate acceleration, though the four-cylinder engine note doesn’t necessarily inspire you.

For the most part the seven-speed dual-clutch operates smoothly, though it can get caught out during low-speed manoeuvres. It’s also clearly tuned for economy as it likes to shift up to the next gear quickly.

The AWD Duster, on the other hand, is where the fun and true character of this quirky SUV shines. With the three-cylinder turbocharged petrol engine and the manual transmission, it’s far from the quickest vehicle out there. It’s faster than a Suzuki Jimny, though.

While progress may be relatively docile, the gruff three-cylinder engine note is addictive. There’s also plenty of torque on tap, so you don’t need to downshift to get things moving.

The manual selector feels chunky in the hand and the clutch biting point is easy to get your head around. Unlike some petrol-powered manual cars, this one’s hard to stall. Even if you do, once you put your foot back on the clutch, the car restarts automatically.

Where the AWD Duster gains extra character points is by having a 48V mild-hybrid system. It doesn’t do anything to drastically alter the driving experience apart from adding a tiny boost to acceleration and extending and smoothing the engine idle stop-start system.

During our launch drive program we had the opportunity to drive the front- and AWD Duster off the beaten path, as well. While you’d expect the latter to be good, the former surprised me in terms of just how far it could go. It’s clear the platform is set up for all-terrain capability, no matter the powertrain configuration.

For added peace of mind off-road, however, the AWD has a higher ground clearance (212mm vs 174mm), as well as a range of terrain modes, including a ‘Lock’ setting that splits torque evenly between the front and rear axles.

The AWD Duster is pretty unstoppable off-road. It’s not quite a Jimny tamer in terms of outright off-road-ability, but I estimate the Duster could do 80 per cent of what a Jimny could do.

While the Duster mightn’t be an outright off-road beast, it well and truly makes it up with on-road finesse. The most noticeable element is the suspension. It feels supple, balanced and controlled no matter the surface. Sure there’s some body roll in the bends, but this isn’t trying to be a sports car.

There are some differences between the front- and AWD Duster when it comes to the rear suspension. The former has a torsion beam set-up, while the latter has a multi-link arrangement. In practice, however, it’s hard to tell any difference between the two.

The steering is direct and on the lighter side which helps with manoeuvrability, though there’s a general lack of feel. It’s considerably better than the Jimny’s vague steering, though.

In terms of parking the Duster has a tight turning circle. Rear parking sensors and a reversing camera are standard in the Evolution, though the Techno adds front and side parking sensors, as well as a surround-view camera.

The camera systems in this car are poor. They’re mushy-looking with poor resolution and horrible colour balance. It’d be great to see higher quality units installed, especially because the multimedia screen is so high-resolution.

Forward visibility from the driver’s seat is fantastic through the rather upright windscreen. You also get a good view of the muscular-looking bonnet.

Side visibility is great, which helps make checking blind spots easier, plus the rear envelope is sizable.

The safety systems in this car are largely easy to live with, though the lane-keep assist can grab at the steering wheel a bit too much on roads with tight lanes or poor lane markings.

Thankfully there’s a button on the dashboard that turns this, and any other safety system that annoys you off, so you can keep on motoring without safety nanny intrusion.

Lastly in terms of noise, vibration and harshness (NVH), the Duster is impressively quiet at low speeds. You can even travel at 60-80km/h along gravel roads and in the cabin it sounds like you’re on a sealed surface.

Once you get out on the open road at highway speeds there’s noticeable road and wind noise, but I’ve experienced much worse in small SUV rivals at a similar price point.

The Renault Duster hasn’t been crash-tested by ANCAP just yet, though the Dacia Duster did receive a three- out of five-star Euro NCAP rating in 2024.

As standard there are six airbags, autonomous emergency braking, lane departure warning, lane-keep assist, driver attention alert, traffic sign recognition, rear parking sensors and a reversing camera.

Stepping up to the Techno gets you blind-spot monitoring, front and side parking sensors as well as a surround-view camera.

Notably absent from the entire line-up is rear cross-traffic alert, as well as adaptive cruise control. There’s only standard cruise control on offer.

There are two ISOFIX points, as well as three top-tether child seat anchorage points on the rear seat bench.

Mercedes-Benz (and by extension Mercedes-AMG) offers a three-year/unlimited km warranty with 24 hour 'Road Care' emergency roadside assistance provide for three years.

Servicing is recommended every 12 months/20,000km and a capped price servicing plan is available at Silver and Platinum levels for up to five years/100,000km.

The Renault Duster is covered by a five-year, unlimited-kilometre warranty with five years of roadside assistance.

Logbook servicing is required every 12 months or 30,000km, which is mainstream for the commercial vehicle segment, but incredibly rare for a regular car. These long intervals are handy for those who travel long distances.

The first five services have capped pricing. All up these cost $2685 for FWD Dusters or $2475 for AWD Dusters. These average out to $537 and $495, respectively, per service.

Alternatively, you can purchase a five-year, pre-paid service plan for $2150 for FWD Dusters or $2100 for AWD Dusters. This is a saving of over $500, depending on the version, compared to pay-as-you-go.
