Mercedes-Benz A45 vs Renault Duster

What's the difference?

The Mercedes-AMG A 45 4Matic+ may have grown up a bit in that it’s not as noisy or uncomfortable as the first-generation version which arrived in 2013, But if anything, its more portent than ever. Superb Mercedes-AMG craftmanship, outstanding performance and good value as far as bang for your buck goes.

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.

When I went to pick up the Mercedes-AMG A 45 S 4Matic+ I walked right past it and then like that lost and confused John Travolta in Pulp Fiction internet memes, wandered around before asking where the car was.

That’s because I was looking for something with a gigantic spoiler on the roof and probably hi-vis green with stripes. But the car assigned to me was the A 45 S in its standard form, and the styling is subtle enough for it disappear into a crowded car park like James Bond into a lavish dinner party.

But like Bond, chances are the A 45 S is the most hardcore person in the room, it just doesn’t walk in announcing it to everybody.

Look closely and you'll see that the A 45 S is not just another small prestige car. There’s the 90mm quad exhaust poking out of the chunky diffuser, the giant 'Panamericana' grille, and the angry looking front apron.

Then, there are the 19-inch matt black alloy wheels wrapped in low-profile Michelin rubber and enormous brake discs with their red calipers, all barely contained by the pumped up front wheel guards which are much bigger than those on a regular A-Class.

The cost option my test car wore was the 'Mountain Grey Metallic' paint, but if anything it made the A 45 look even more covert.

The cabin is small but luxurious and sporty with two-tone leather upholstery (the red and black 'Lugano' leather in my test car is a no-cost option), there’s the microfibre-clad AMG steering wheel, brushed aluminium trim, metal-trimmed pedals and the large display panel (it’s actually two screens joined) is also standard.

The A 45 S is a hatchback measuring 4445mm in length, 1850mm wide and 1412mm tall. Not keen on a hatch but want something with similar dimensions? The CLA 45 S is the A 45 S’s four-door twin-under-the-skin and is just as much of a weapon.

And if you want your A 45 S to look more aggressive, you can option the 'AMG Aero Package' which will see a giant rear wing fitted to the roof.

Or you can buy the Edition 1 version of the A 45 S which includes the big spoiler and shouty design bits to makes sure everybody knows you’re the assassin in the room.

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.

Along with good performance and handling, part of the appeal of hot hatches is that they’re practical… to a degree. The A 45 S is a small car, but it has four doors, five seats and a boot.

The cabin is small, no doubt about it, but even at 191cm tall I had plenty of room while driving, the seating position is perfect actually, although sitting behind my driving position saw my knees just touching the seat back.

Headroom is getting limited back there, but I still had space. Could you get away with the A 45 S as a family car? I had my family in it for a while, but there’s just the three of us and my son is pre-school-aged. So, a young, small family, yes… until it starts to grow.

Cabin storage is good with two cupholders in the rear centre fold-down armrest along with small door pockets and seat-back nets. Up front there are another two cupholders, giant door pockets, a big split-opening centre console bin and a tray for the wireless charger big enough to fit an iPhone 11 Pro Max.   

Boot space is good at 370 litres. The big shiny CarsGuide suitcase fitted in easily (see images) and apart from the wide-opening of the boot, another hatch power of practicality is that you can fold the rear seats down to open up more cargo carrying space, and in the A 45 S’s case that’s 1210 litres.

I’ve mentioned the wireless charger but there are also four USB-C ports (two up front and two in the rear), back seat passengers also have directional air vents, which is another bonus, along with dark tinted windows (welcome when my son was sitting back there in his car seat).

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.

There may be hot hatches out there which look wilder than the Mercedes-AMG A 45 S 4Matic+ but do they have the most powerful four-cylinder engine ever to go into a mass-produced car? Nope, but the A45 does: it’s a 310kW/500Nm turbo-petrol four.

It doesn’t sound as angry and gravelly as the previous A 45’s engine but it has more grunt (an extra 30kW/25Nm) and is claimed to catapult the hatch from 0-100km/h in 3.9 seconds.

The '4Matic' part of the name indicates the hatch is all-wheel drive and the '+' means it’s a more sophisticated version of the system which allows all of the drive to be sent to one axle, if need be.

What need would that be? The need to drift, of course, which should be up there with other human rights such as clean air, fresh water and free speech.

Yep, the A 45 S comes with 'Drift Mode' (for the racetrack, of course), along with a 'Launch Mode' for perfect-every-time transitions to warp speed.

Changing gears gunslinger-fast is an eight-speed dual-clutch automatic transmission.

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.

Mercedes-AMG says the 2.0-litre, turbo-petrol, four-cylinder in the A 45 S should use 8.9L/100km after a combination of open and urban driving.

My fuel test saw me drive 131km of urban and country roads, plus some motorway sections, and needed 16.9L of premium unleaded petrol to fill the 51-litre tank back to full.

That comes to 12.9L/100km, which is thirsty, but my driving style may have contributed significantly to that high figure.

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.

I wasn’t lying in the introduction to this review. The previous A45 was a pretty intense driving experience. The ride felt brutal, the exhaust note screamed and crackled like somebody had set a wheelie bin full of fireworks alight.

And then there was the sweating. I seemed to sweat a lot driving it and there was nothing wrong with the climate control, that just happens to me when I’m under pressure and excited.

So, has the new-generation A 45 S 4Matic+ gone all soft and quiet on us? No, but things have been toned down a tad.

The exhaust note is not as gruff or loud, and even in 'Sport +' and 'Race' mode it’s still quiet enough to pull into a driveway at night without making enemies of your neighbours.

And the ride is also not as harsh, although even in 'Comfort' mode my wife still found it verging on too firm.

The performance and dynamics, however, felt as sharp as ever.

Acceleration is supercar quick at 3.9 seconds. My gawd, you needed a Ferrari F40 to do that in the mid-’80s, and even now the new Mercedes-AMG GT S supercar gets there only a tenth of a second earlier, and it has a twin-turbo V8.

Top speed for the A 45 S is electronically limited to 270km/h. But hot hatches aren’t really about straight-line speed, they’re more about bent-line speed. You know, corners.

So, I took the A 45 S on the twisty roads I take anything that calls itself sporty. The agility of the A 45 S is outstanding thanks to a rigid chassis that handles a change in direction as quickly and easily as you can turn your head.

The brakes bite hard when they have to, and the all-wheel drive hatch scrambles tenaciously out of corners.

A racetrack is really the best place to truly test a serious sports car's limits and our own James Cleary did just that when he drove the A 45 S at its international launch.

As a daily driver, though, for somebody who occasionally likes to get into it on a curvy road the A 45 S is comfortable enough to live with, but hard enough to remain engaging and dynamic when you get the chance to have a squirt.

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.

The Mercedes-AMG A 45 S 4Matic+ is covered by a five-year/unlimited kilometre warranty.

Servicing is recommended at 12 month/20,000km intervals. Servicing is capped at $850 for the first year’s visit, $1200 for the next and $1600 for the third.

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.
