Mercedes-Benz GLA45 vs Renault Duster

What's the difference?

A performance SUV should be an oxymoron and is no doubt a niche product. Is it a high-riding hot hatch? Or a mega-potent small SUV?

Turns out the Mercedes-AMG GLA 45 S is a bit of both and delivers the thrills of a performance car without any of the packaging or comfort-related issues.

While it is getting a little expensive at over $100,000, its blend of space and pace is hard to beat.

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.

The most obvious tell that the GLA 45 S is something a little special is the Panamericana front grille, an ode to the 1952 Mercedes 300 SL, which is found on all of the German brand's hot models.

But if that wasn’t enough to give it away, the reworked bumper with larger intakes, red-painted brake calipers, lower ride height, black exterior trim and 20-inch wheels should help.

Coming round to the rear, if the AMG and GLA 45 S badges aren’t enough to give away this car’s sporting intent, the quad-exhaust tips and diffuser are sure to give any tailgaters pause.

Our car also came with the optional 'Aerodynamics Package', which adds front fender flicks and a massive roof-mounted rear wing for an even racier look.

If you think the GLA 45 S looks a bit like a jacked up hot hatch, you aren’t far off. Overall, we reckon Mercedes has done a great job at translating the aggressiveness of its A 45 hatch to the larger, higher-riding GLA.

Without the aero package optioned, you might even call it a bit of a sleeper, and it’s certainly more subdued in styling compared to its Audi RS Q3 rival.

In fact, the GLA 45 S might be too subtle for such a hot SUV, at least for our tastes.

Whereas the A 45 S and CLA 45 S get bulky fenders and a hunkered-down, aggressive stance, the GLA 45 S could just blend into the sea of SUVs seen out on the streets, especially without the aerodynamics package added.

Your mileage will vary though, and for some, the subtler looks will be a positive.

Anyone who has sat in a recent small Mercedes should feel right at home in the GLA 45 S, and that’s because it shares much of its interior design with the A-Class, CLA and GLB.

As mentioned before, the 10.25-inch centre screen takes care of multimedia duties, but there are also clicky and tactile buttons underneath for climate controls.

Key to the interior design though is an all-digital instrument display, which is laid out on the high-definition 10.25-inch screen.

With two screens facing you, you might think it’s a bit of information overload, but you can tweak each display to show the information you want.

The digital instrumentation might not be as intuitive as Audi’s 'Virtual Cockpit', but the layout and design of the interior is easy to use and offers owners plenty of customisation to get it right.

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 new-generation GLA 45 S has grown in all dimensions compared with its predecessor, making it much roomier and more practical than before.

For reference, it measures 4438mm long, 1849mm wide, 1581mm tall and features a 2729mm wheelbase, but still sports a roomy cabin for four adults, especially in the front seats.

Storage options include decent door pockets that will accommodate large bottles, a deep centre storage bin, smartphone cradle that doubles as a wireless charger, and two cupholders.

Being a small SUV, the rear seats also afford plenty of room for occupants, with more than enough space for head, shoulders and legs – even with the front seat adjusted to my 183 cm (6'0") frame.

There are decent door pockets, air vents, and USB-C ports that should keep passengers happy on long trips, but the GLA 45 S doesn’t have a fold-down armrest or cupholders for the rear seats.

The boot, however, is where the GLA 45 S really starts to make a case for itself compared to the A 45 S.

The boot boasts 435 litres of volume, and can expand to a massive 1430L with the rear seats folded – making it about 15 per cent bigger than the A 45 S – while the higher load height should make loading and unloading groceries a bit easier. 

A downside of the GLA’s tech-focused interior, though, is that all the USB ports are now USB Type-C, meaning you’ll likely have to carry around an adapter to use your old cables.

Mercedes is generous enough to include one with the car, but given most device chargers are still USB Type-A, it is something to be aware of. 

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.

Powering the Mercedes-AMG GLA 45 S is a 2.0-litre turbocharged petrol engine, outputting a staggering 310kW/500Nm.

This means the new car jumps up 30kW/25Nm compared to its predecessor, explaining (at least in part) the price jump.

The GLA 45 S is also the top-spec version globally. The 285kW/480Nm GLA 45 which is available overseas would be more directly comparable to the old car.

The engine is also the most potent production 2.0-litre on earth, and is shared with the A 45 S and CLA 45 S.

Paired to the engine is an eight-speed automatic transmission, which sends drive to all four wheels via Mercedes’ '4Matic' system.

As a result, the GLA 45 S will accelerate from 0-100km/h in a frighteningly quick 4.3 seconds, and carry on to an electronically limited top speed of 265km/h.

This is 0.4s slower than its A 45 S sibling, in part due to its heftier 1807kg weight.

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.

Official fuel consumption figures for the GLA 45 S are pegged at 9.6 litres per 100km thanks in part to an engine start/stop system.

We managed 11.2L/100km after a few days of testing around Melbourne’s inner city and winding country back roads, but those with lighter feet will no doubt come closer to the official figures.

A performance SUV that can ferry kids and groceries, out accelerate  nearly everything else on the road, and sip around 10L/100km? That’s a win in our book.

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.

If the bespoke styling wasn’t enough of a giveaway, all it takes to realise you are behind the wheel of something special is to turn on the GLA 45 S.

The prodigious engine is fantastic in the A 45 S and CLA 45 S and is no different here.

With peak power coming in at a heady 6750rpm and maximum torque available from 5000-5250rpm, the GLA 45 S likes to rev and makes it feel a little like a naturally aspirated engine in character.

Don’t get us wrong, once the boost becomes available, you will feel that shove into the back, but it’s great that Mercedes has made the engine perform a little more predictably.

Paired to the engine is a smooth shifting eight-speed dual-clutch automatic transmission, which is one of the better versions I've experienced.

Many DCT bugbears, such as jerkiness at low speeds and clunkiness when putting into reverse, aren’t apparent here, and the transmission is up to the task when puttering around town or when driving spiritedly.

Speaking of which, the GLA 45 S’ different drive modes will easily change its character from tame to wild, with available options including ‘Comfort’, ‘Sport’, ‘Sport+’, ‘Individual’ and ‘Slippery.’

Each mode will tweak the engine response, transmission speed, suspension setting, traction control and exhaust, while each can also be mixed and matched in the ‘Individual’ drive mode.

However, a missing feature for the GLA 45 S that is found in its A 45 S and CLA 45 S siblings is a drift mode.

Sure, how many small SUV owners are going to take their car to a track to make use of it, but it still would have been nice to have the option.

With three levels of suspension setting, though, the GLA 45 S offers enough variability to be comfortable around town and soak up the bumps thanks to its long suspension travel, while also switchable for a more involved, driver-focused feel.

The GLA 45 S might never corner as hard or fast as its A45 S sibling, but being an SUV brings its own unique set of plus points.

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.

Like all new Mercedes-Benz models, the GLA 45 S comes with a five-year/unlimited kilometre warranty with five years of roadside assist – the benchmark in the premium car space.

Service intervals are every 12 months or 20,000km, whichever occurs first, and the first five services are available to purchase for $4300.

This actually makes the new GLA 45 S cheaper to maintain over its first five years than the outgoing car, which costs $4950 over the same time period.

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.
