Kia Optima vs Renault Duster

What's the difference?

If you travel long distances, want a good amount of space and don’t want to pay big bucks for a new car, then yeah, maybe there is a reason sedans like this will hang around for a while longer.

Sure, the appeal of sedans mightn’t be as strong as it once was, but models like the Kia Optima prove they still have a reason to exist.

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.

Cosmetic changes for the facelifted 2018 Kia Optima include new headlights and tail-lights with revised LED signatures (but still halogen lamps in the base model), and there are newly sculpted bumpers and new wheel designs across the two-model range. 

We had the base model Si, which doesn’t look as good as the GT model, because it has smaller wheels, the sporty body kit and misses out on the LED headlights, but the LED daytime running lights are still present.

The GT has a more aggressive look, and the side skirts, front spoiler and rear diffuser fit it better - there are dual exhausts, but not sporty quad exhaust tips.

In fact, this model is a bit like the old-man version of the Optima. No offence intended to old men, of course. The GT is just heaps sportier, and I reckon it’s considerably more attractive as a result. 

Still, the inherent sleek styling of the Optima remains - the chrome highlighting along the window line is a bit too sheeny for me, but the angles and stance of this model are quite gracious. I really dig the fact the top of the windscreen mirrors the ‘Tiger Nose’ grille shape.

I'm no exterior designer, but I liked the existing Optima more - it just looked a bit neater, even though it had a decent amount of bling with its Mercedes-like diamond-pattern grille, as opposed to the cheese grater look seen here.

There’s not quite as much bling inside the cabin of the Si, either, but it is still a well-designed space - just not as special as the premium package offering of the GT (which gets leather trim - not nappa leather, but still a quality cowhide finish, and more). Check out our interior photos to see if you agree - but size and interior dimensions of the Optima are hard to argue against.

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.

I really like the way Kia designs its cabins. Sure, there’s a lot of black in here, but there’s also a lot of thought put into the usability of the space.  

The high-mounted 7.0-inch infotainment and multimedia touch screen in the Si is simple to use, and for 2018 the Optima range gets Apple CarPlay and Android Auto - you couldn’t get that in the Optima up to this point. 

Also included are a reversing camera, USB input, Bluetooth phone and audio streaming and six speakers. The Si model misses out on sat nav - you’ll have to use the maps app on your phone. No DVD player either.

Storage is well thought out in here, with big bottle holders in the doors, a good sized pair of cup holders up front, and a nice little storage bin for your phone, wallet, keys and so on.

There’s a driver info screen with a digital speedo, and even on this base model you get a dual-zone climate control air conditioner. The updated Optima gets a new steering wheel, too.

Now, what about the back seat?

It may be considered a ‘mid-sized’ sedan, but there’s limo-like space. With the driver’s seat in my position (I’m about six feet tall) there was still heaps of rear legroom in the rear seat, with ample knee room, good foot room and decent shoulder space, too - three of me could slot across the back bench comfortably, which means kids will fit easily, too. There are three top-tether points and two ISOFIX points as well.

Kids and adults alike will be happy with the rear air vents back here, and there’s a flip down armrest with cupholders, too. Again, big bottle holders appear in the doors, and there are map pockets in the back seats.

What about boot space? With so many people choosing SUVs over sedans because they’re theoretically more practical, the Optima offers good food for thought - it has enough luggage capacity for a bunch of suitcases (510 litres VDA in size) and there’s a full-size alloy spare under the boot floor. If you need more, you could always invest in a roof rack setup?

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 Si model is powered by a 2.4-litre four-cylinder petrol engine, which has seen no changes to its specifications for this mid-life update.

Engine specs remain at 138kW of power at 6000rpm, while torque is rated at 241Nm at 4000rpm. It makes use of a six-speed automatic transmission only - there’s no manual transmission here, but you do get paddle shifters - and it's front wheel drive (the Optima isn't available with AWD, or as a 4x4, or in rear wheel drive - the latter is left to its bigger brother, the Stinger).

The GT gets a zestier drivetrain with more horsepower - it has a 2.0-litre turbo four-cylinder engine with 180kW/350Nm, which is much more desirable, but also louder than the Si’s 2.4. It also has a six-speed auto transmission, and is FWD. If you're into ratings and statistics, that 2.0-litre with a turbocharger is one of the perkier offerings for its engine size in the class.

There is no hybrid model available, despite a plug in hybrid petrol version (allowing you to run in EV mode) being sold in European markets. No diesel here, either, while other markets get a 1.7-litre turbo diesel. No LPG model here, or anywhere else, for that matter.

Towing capacity for Optima models is 750kg unbraked and 1700kg braked for the 2.4-litre, and 700kg/1400kg for the 2.0-litre turbo. Tow bar down-weight is capped at 80kg.

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.

Kia claims a very realistic fuel economy rating of 8.3 litres per 100 kilometres for the Si model, and we saw damn close to that consumption during our week of testing. On the highway it will sit at around 6.5L/100km, ensuring good mileage, while city driving will push usage above 12.0L/100km. Our overall average was 8.5L/100km, which is good. Use the eco mode, and you'll get a little better use.

The turbocharged GT model uses a little more, according to Kia’s 8.5L/100km combined average claim, but we guarantee you’ll actually use more than that because it’s more eager to please.

Fuel tank capacity is 70 litres - plenty of size for long distance drives.

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.

The Optima has some really good elements to the way it drives, but sadly  some less impressive bits as well.

Let’s start with the not-so-great stuff - the 2.4-litre engine in this Si model just isn’t as enjoyable as the turbo unit, and the fact that Kia still doesn’t offer a hybrid version here, despite doing so elsewhere, is a bit of a downer.

The drivetrain isn’t terrible - the six-speed auto is smart enough, and there’s usable power if you boot it. The two more sedate drive modes, 'Eco' and 'Comfort', mean the transmission will aim to save fuel and limit throttle response, with a bit more of a lazy feel to the drive experience. But in 'Sport' mode it is definitely more rewarding in terms of acceleration and performance, offering a bit more pep and urgency (we didn't do a 0-100 km/h speed test, but take our word for it); it undoubtedly at the cost of fuel consumption.

It’s just a bit of a shame Kia doesn’t offer the turbo in this spec, too. Fuel use for the Si model is better than the turbo, however, so it could be ideal for buyers who are more worried about the bottom line than design and a sportier drive.

The thing I like most about the Optima is its road manners - the steering and suspension have been tuned for local conditions, just like all Kia products, and it shows. 

The electric power steering is really well sorted, making for easy parking moves and good assuredness at higher speeds. And the turning circle is decent, too - 10.9m (so, the turning radius is 5.45m). 

Plus the ride comfort is really good. On the highway it coasts along with very little fuss, and around town it deals with lumps and bumps impressively. Sharp edges can upset things a tad, and mid-corner bumps can make it jitterbug a little bit, but not to a degree that would rule it out of contention if you want a mid-sized sedan.

It’s pretty quiet on the open road, too, and the adaptive cruise control makes long-distance driving a simple task. The GT does suffer a little bit more road noise, though.

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.

Kia remains a shining light in terms of its new-car-ownership promise, with a very strong seven-year/unlimited kilometre warranty. It makes a lot of sense if you plan to hang onto the car for a while. There's no extended warranty available, which is understandable.

That plan also includes a roadside-assist plan for the same seven-year period, provided you maintain your car with Kia Australia. So, given you get one year to start with, then you get an extra year of cover every time you go back to Kia to get your car serviced, you could end up with eight years of coverage. Nice!

Servicing is due every 12 months or 15,000km, with the first seven years covered by a capped-price-service cost / maintenance cost plan. The costs are: service one - $289; two - $466; three - $360; four - $559; five - $325; six - $599; seven - $345. That makes a total cost of $2943, which is competitive for its class. Keep your owners manual or logbook up to date, and your resale value should hold up better.

If you have concerns about common problems, issues, reliability ratings and durability, you should check out our Kia Optima problems page.

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.
