Kia K4 vs Renault Duster

What's the difference?

The new Kia K4 GT-Line has a lot to offer - an interesting design, lots of features and a pleasant driving experience. It’s not without its quirks and there are times when a more powerful engine may have improved it for me as a long-term prospect as I do some big kays every year but it ticks the boxes as a friendly urban dweller.

The Renault Duster 4x4 Evolution (manual) is a driver’s car. Lots of fun for day-to-day duties and a real visceral experience if you like to have a few laughs on loose-dirt and gravel tracks. And it’s adequately capable for off-roading adventures. It also has more than its fair share of cheeky charm.

Obviously it’s not anywhere near the most capable off-road vehicle available. That’s not what it’s intended to be. But it’s one of the most fun to drive on- and off-road.

And for $36,490 (excluding on-road costs), you’ll still have cash enough for a set of all-terrain tyres and some accessories.

Have to admit I wasn’t convinced on the design of this new sedan at first as it can look a little out of sorts from certain angles. But the more time I spend with it, the more I appreciate its sharp lines and sporty rear shaping.

The small sedan market doesn't have a lot of options now because SUVs are so popular but it's nice to see a design that stands out and the fang-like LED light design at the front and rear, as well as the 18-inch alloy wheels make the K4 look very cool.

The rear doors look sleek because the handle has been hidden in the C-pillar and the K4 is particularly striking in our test model's 'Wave Blue' ($600 RRP) paint colour.

Head inside and you'll find a cabin that looks slick with a two-tone synthetic leather upholstery that feels supple underhand and a plethora of soft touchpoints under all the bits that touch.

The black headliner creates a posh space but the sunroof helps the cabin to feel airy when you need it to.

The dashboard isn't too wide, preferring a sharply linear shape and is headlined by a massive display panel that houses dual 12.3-inch screens and a 5.0-inch climate panel.

There is still a strong presence of plastics inside but you don’t tend to focus on them.

Unlike some other new cars hitting our market, the K4 hasn’t done away with its buttons and dials - and there’s enough to satisfy those who don’t like to rely on a screen for everything. The extra traditional element of the physical gear selector adds to its charm as well. 

From the outside, the Duster 4x4 Evolution has that special ‘something’ that draws your eye. It’s unassuming, yet somehow eye-catching.

It’s a chunky little AWD with ‘Renault’ across the front grille and its raised stance gives the Duster a rugged presence.

Hard angles and nifty touches, such as the concealed rear door handles on the C-pillar, add to its funky exterior.

The Duster’s interior continues the minimalist theme with hard plastic surfaces everywhere – including the dash and door armrests – and black and grey cloth upholstery, all amid a neat but uncluttered layout.

The 10.1-inch multimedia touchscreen , angled slightly towards the driver, dominates up front and caps off what is an unpretentious, functional cabin.

The K4 feels big for the class, especially compared to its nearest rivals and that translates to a cabin that feels adult-friendly in both rows. An impressive feat for a small sedan.

Access is the only time you will have moments of 'I should have opted for an SUV'. That's because you will get in your daily squats sliding in and out of the K4 due to its 140mm ground clearance.

The rear doors also feature a wide wing that juts out from the door handle and it catches your hip almost every time you go to close the door.

The wide front seats offer lots of comfort with thick padding and long under-thigh-support. The driver's side is powered with adjustable lumbar support but the passenger seat only offers manual adjustments, which is surprising for a top-grade model. However, both front seats enjoy heat and ventilation functions.

The back bench seat offers similar comfort to the front with seat padding and length but it's not terribly wide and two adults (or child car seats) will fit best.

Amenities and storage is decent for the class with each row enjoying four drink holders and two USB-C ports. Front rowers also get a wireless charging pad and 12-volt socket.

In the front there is a large glove box that fits more than just an owner's manual, a mid-size middle console and a centre console that features retractable cupholders to open up the space if you need to. A dedicated phone cradle with small spaces on each side rounds up individual storage for the front.

In the rear there are two map pockets, a small item cubby next to the USB-C ports and a pair of directional air vents, reading lights and a fold-down armrest.

The boot space is massive for the class at 508L (that's nearing mid-size SUV territory) but the aperture is narrow and I couldn't fit my big booster seat through the opening.

The boot is quite deep as well and you may find yourself climbing into it to retrieve items that roll into the back.

The rear bench seat has a 60/40 split which can help with storage and there is a temporary spare tyre underneath the floor.

While you don't get a powered tailgate in this model, the lid isn't heavy to operate and has a proximity opening function that keeps it practical when you have your hands full.

This just means when you approach and stay near the boot with the key fob on your person the boot lid will pop open for you.

The 12.3-inch touchscreen multimedia system looks great with crisp graphics and a responsive touchscreen. The menus are in an easy-to-understand layout which you'll get accustomed to in no time. The 5.0-inch climate display sits to the right of this system and it's nice to have it on display all the time.

The 12.3-inch digital instrument cluster isn't all that customisable but it's easy to read with large text and a small menu screen that shows nav directions, trip info or a compass.

The built-in satellite navigation system is easy to get going and to cancel a route guidance, it's a one button affair which is great for when you're on the go.

The system features wired and wireless Apple CarPlay and Android Auto. The CarPlay is simple to connect to and retained a steady connection this week with feedback from my callers that my voice was clear on calls.

The interior in Evolution trim matches the Duster’s no-nonsense adventure-focussed approach. It’s spartan but user-friendly.

The front seats are manually adjustable and the cloth upholstery looks like it’s hard-wearing and likely able to cope with the utter messiness of life.

I had trouble getting my phone to work via the 10.1-inch multimedia unit, but otherwise I have few complaints about the system as it’s easy enough to operate. There’s a wireless-charging pad below the screen. There are also two USB-C charging ports up front and two for rear-seat passengers, as well as two 12-volt sockets one in the front and another in the rear cargo area.

There is a mix of physical buttons and on-screen controls to operate various in-cabin functions, such as air-con.

For storage there is a glove box, a deep centre console, two cupholders, and a small shelf for your pocket clutter.

The second-row seats are roomy enough for two adults or three teens across the row and while passengers there have access to two USB-C charging ports and air vents, there’s no fold-down centre armrest.

The rear cargo area is accessed via a manual tailgate and is claimed to offer 358 litres of cargo volume when the rear seat is in use and 1424 litres when the second-row seat is stowed away.

Payload in the Duster Evolution 4x4 is listed as 503kg. The cargo area has a light, cargo hooks and a 12V socket. This Duster has a 215/70 R16 spare stored underfloor.

The 2026 Renault Duster is available as a 4x2 (automatic) or 4x4 (with a six-speed manual) in two trim levels – the Evolution and the Techno – with a choice of a turbocharged 1.3-litre four-cylinder engine (for the 4x2) or a turbocharged 1.2-litre mild-hybrid three-cylinder engine (for the 4x4).

Our test vehicle, the 4x4 Evolution, has a manufacturer suggested retail price of $36,490, excluding on-road costs.

Standard features include a 10.1-inch multimedia touchscreen (with wireless Apple CarPlay and Android Auto), a wireless smartphone charger, 7.0-inch digital instrument cluster, six-speaker Arkamys sound system, dual-zone climate control, 17-inch alloy wheels, Continental Cross Contact 215/65 R17 tyres and a 215/70 R16 spare.

There’s also a range of accessories available including Rhino Rack and Thule storage platforms and racks.

Exterior paint choices include the no extra cost 'Solid White' as well as 'Khaki Green', 'Pearlescent Black', 'Terracotta', 'Cedar Green', 'Sandstone' and 'Shadow Grey'. All metallic or premium paint adds $750 to the Duster’s price.

The flagship grade is front-wheel drive and has a 1.6-litre four-cylinder, turbo-petrol engine that produces up to 142kW of power and 265Nm of torque giving this a more powerful presence than its non-turbo siblings (which only produce up to 112kW/192Nm).

However, while the power is adequate for the GT-Line there are times when the engine sounds like it's working a bit too hard.

The eight-speed torque-converter automatic transmission can also become flustered as it moves through the lower gears, especially when you’re accelerating quickly.

On the whole, the power delivery and outputs are more than enough for a city environment and the odd road trip.

The Duster 4x4 Evolution has a 1.2-litre three-cylinder turbo-petrol engine with a 48V mild-hybrid system (producing 96kW at 4500rpm and 230Nm at 2250rpm) matched to a six-speed manual gearbox.

As I said earlier, a new small 4x4 SUV with off-road capability and a manual gearbox is refreshing.

This Duster has an all-wheel drive system and the little 1422kg SUV can do the 0-100km/h sprint in a claimed 11.94 seconds.

With an official combined (urban/extra-urban) cycle fuel usage figure of 6.7L/100km and a fuel tank size of 47L, this model has a theoretical driving range of 701km. That does sit around 80 kays less than some of its rivals but it’s still sufficient for those wanting to do the odd road trip!

My on-test fuel usage has popped out at 9.2L/100km, which is based on figures achieved at the pump (32.05L) and my km travelled (348km).

I’ve done mostly urban trips this week with one longer open-road drive and overall I’m not too surprised by that figure because I’ve been pushing it hard but it could be better.

The K4 is a simple gal because Kia recommends a minimum 91 RON unleaded petrol to be used for all models.

Official combined cycle (urban/extra-urban) fuel consumption is 5.7L/100km.

On test, we recorded 6.7L/100km but we did do a half-day of light off-roading.

This Duster 4x4 has a 55-litre fuel tank so, going by that on-test fuel figure, you could reasonably expect a driving range of about 820km out of a full tank.

The turbocharged 1.2-litre mild-hybrid three-cylinder engine requires 95 RON premium unleaded petrol.

As mentioned earlier, the power is adequate to move this car around on the open-road but you have to be a little aggressive on hills to keep your speed consistent.

It’s not always quick off the mark, though, and you’ll notice that when you have to cross traffic or enter a roundabout - so allow for extra car lengths. Once you get going, it’s responsive in the city.

The steering is sports-stiff and so is the suspension. This makes the handling feel nimble in turns and sure-footed when doing quick lane changes but you hear and feel every bump in the road. 

On-road comfort is okay around the city but the road noise is very loud inside the cabin and is particularly noticeable at higher speeds. You’ll have to raise your voice to chat to passengers in the back when you're on the highway.

The K4 has a small turning circle of just 10.7m and you can easily do a U-turn in spaces that others might have to do a three-pointer. This made the K4 feel friendly in small car parks and on ramps.

The direct steering makes it easy-enough to park, as does the reversing camera and front/rear parking sensors but I’m pretty disappointed that at the top grade-level, you miss out on a 360-degree camera system (tsk, tsk, Kia).

My kids are learning to drive in a manual because I reckon being able to drive a manual vehicle remains an important skill to have. I only own manual cars at this point in time and it’s nice to see new cars with manual gearboxes haven’t been done away with just yet.

This all-wheel drive adventure machine is light at 1422kg and punchy, working through a turbocharged 1.2-litre mild-hybrid three-cylinder engine (producing 96kW at 4500rpm and 230Nm at 2250rpm) and a six-speed manual gearbox.

It’s sporty, with precise steering, crisp throttle response and nicely controlled ride and handling. And it’s a whole lot of fun to drive on sealed surfaces.

Throwing it around corners at (legal) speed is a barrel of laughs and driving on fast loose-dirt tracks is damn good for rally-style hilarity, all with the gruff backing track of this little AWD’s tractable petrol engine. Driving the 4345mm long, 2069mm wide and 1650mm high Duster feels like you’re punching a go-kart around a track, in a good way.

The Duster’s suspension deserves a mention here because this package, including an independent multi-link set-up at the rear, yields a firm but well-balanced overall feel.

Its tight turning circle makes it supremely easy to accomplish quick manoeuvres without fuss and it’s also a cinch to park.

Visibility from the driver’s seat is somewhat reduced through different angles to the rear and back along the vehicle’s side, but you get used to that. It doesn’t help that the camera view is muddy looking on the screen.

Those niggles aside, did I mention it’s fun to drive?

It’s not too shabby in low-speed off-road scenarios, either. The Duster is similar to Subaru’s Crosstrek and XV or the Jimny, in that this Renault’s intended use is not as a hardcore rock-crawling beast, it’s not engineered for that sort of thing.

The Duster's all-wheel drive system is well calibrated and quietly effective at detecting wheel-slip and delivering a smooth response. Driven with care, this AWD SUV is capable of off-roading at a level that will surprise some.

It has a 4x4 terrain control system with five modes – 'Auto', 'Eco', 'Mud & sand', 'Snow' and 'Off-road' – as well as a hill descent control system. None of these are engineered to turn the Duster into an off-highway mongrel but they ensure it's able to cope with mild to less-mild off-roading.

The Duster’s ground clearance (212mm) and off-road angles (31-degree approach and 36-degree departure) make it better suited to tackling off-road terrain of the light-to-moderate variety rather than door-sill deep mud holes and the like.

For reference, the Suzuki Jimny has 210mm of ground clearance and approach and departure angles of 37 and 49 degrees. The Crosstrek has 220mm of ground clearance, and approach and departure angles in the off-road-focussed Wilderness of 23.5 and 25.5 degrees.

But it’s still very capable if driven with consideration and well within the limits of its physical dimensions and off-road traction control.

Light off-roading (well-maintained gravel roads and dirt tracks in dry conditions) is fine because that’s well within the Duster’s capabilities and it results in little to no wear and tear on the vehicle.

While the Duster can handle short bursts on firm-packed sand (which I test here), sand-driving puts extra stress on any vehicle, and AWDs don’t have a lot of ground clearance, so they’re prone to bellying out on tall crests in between deeper wheel ruts on a beach.

My advice? Avoid anything beyond a well-maintained dirt track in dry weather and don’t take on any ‘4WD/ high ground clearance only' tracks, prolonged sand-driving or rock-crawling. Anything more rigorous than that and you risk damage to the vehicle’s underbody at a minimum, and mechanical damage and personal injury at worst. You’ve been warned.

The Duster’s off-road capabilities could easily be further enhanced with a set of decent light truck all-terrain tyres but, be aware, even aggressive rubber won’t turn it into a gung-ho off-roader.

For the record, it has unbraked trailer towing capacity of 750kg and braked towing capacity of 1500kg. Maximum towball download is listed as 75kg.

A bonus for Duster owners is that it can be kitted out for adventure via either Renault’s range of accessories – including all-weather floor mats, roof box, roof racks etc – or through Australia’s aftermarket industry.

The Renault Duster 4x4 Evolution (manual) does not have an ANCAP safety rating because it has not been tested.

Standard safety gear includes six airbags, AEB, driver attention alert, lane-keep assist, lane departure warning, traffic sign recognition, rear parking sensors and a reversing camera.

The Duster range does not have adaptive cruise control (only regular ol’ cruise control) or rear cross-traffic alert.

The rear seat has two ISOFIX points and three top-tether child-seat anchorage points.

The K4 GT-Line is offered with Kia’s seven-year/unlimited-kilometre warranty. That’s a pretty good term for the class and there is a seven-year capped price servicing program for a flat $3877 (averaging $554 per service), which is slightly more expensive than others in the class.

Servicing intervals could get annoying if you do big kays every year as they're spaced at every 12 months or 10,000km, whichever occurs first.

A five-year/unlimited-kilometre warranty with five years of roadside assistance applies to the Duster. That's average for the mainstream market.

Servicing appointments are set at 12 months/30,000km intervals, whichever occurs soonest.

Capped price servicing applies to the first five services with a total cost calculated at $2475 for the all-wheel Duster, with an average per-service cost of $495, which is getting up there for a car in this price bracket.

Renault has more than 70 dealerships across Australia.
