Subaru Outback vs Kia K4

What's the difference?

Over 30 years and seven generations of Outback in Australia, the latest might just be the best.

It's great to drive, even better to sit in, very easy to live and willing to go further than most equivalent large SUVs at its price point.

The styling is definitely divisive, with purists unhappy that the long, crossover wagon silhouette is now gone, but what we have instead is a family-friendly vehicle that pleases on so many fronts.

We’d go as far as saying the latest Outback might be the most-rounded Subaru currently available, and great value to boot. And the base AWD is all the SUV most people will ever need.

That’s not bad for something this square!

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.

Historically, Subarus have majored on quirky. Kooky even.

Think buggy ‘60s 360, offbeat ‘70s 1400, spacey ‘80s Vortex, futuristic ‘90s SVX, Alfa-esque ‘00s pre-facelift Tribeca, dorky ‘10s Exiga. We’d go as far as saying that, in over 50 years, only a handful of Subarus have looked normal. And they’ve all been boring. The beautiful ones, like the original Impreza and ’03 Liberty, remain stunning.

But quirkifying such an important family car in such a mainstream segment… that's risky. And we’re here for Subaru’s boldness. We just wish the details weren’t so heavy handed.

Longer, larger and wider than any prior version, the 2026 Outback shares its stretched platform architecture fundamentals with the latest Forester. That’s a sound basis. Just Xeroxed up by about 15 per cent. Boxy shape. Deep glass. Wide doors. Form over function. This is designed to make life easier.

What you make of the Wilderness’ visual features, including the dramatic grille mask, SUBARU wording, painted trim surrounds and cladding-on-cladding (behold the Kia Tasman-like squared-off wheel arches if you dare) is down to personal taste. Eyes be damned! But it is so far-removed from the elegant grace of the previous model that some might argue a name change would at least have silenced the critics.

On the other hand, besides fugly being in Subaru’s DNA, a large, lofty SUV is probably truer to the term ‘outback’ than on any elegant and gracefully-silhouetted crossover wagon.

Meanwhile, the polar opposite is true inside. It’s as if the interior designers strove for class and calm, with none of the exterior styling’s visual noise, or shouting in the Wilderness’ case. And there is the luxury of space, vision and scope, further enhancing the Outback’s usefulness. That you can’t see the body, just the beautiful cabin’s detailing, elevates this Subaru. Unlike in the previous model, which was a bit of an aesthetic and functional mess inside.

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. 

Like all Subarus, Outback boasts an interior of very high-quality craftsmanship, being built beautifully, without rattles or noises or jarring trim.

The difference here is just how pleasingly practical and easy yet attractive this environment is, from the moment that wide-opening door opens and shuts with reassuring solidity.

The horizontal dash layout departs from the Tesla-aping portrait screen domination of the previous generation, banishing the confusing and annoying virtual controls for real, live buttons.

But is it original? The layered presentation is attractive and distinctively Toyota… err Subaru. Yes, it is very much like the bZ4X-based Solterra EV’s look inside.

That’s no bad thing from an ergonomic point of view. The driving position is flawless, the seat/wheel/controls relationship considered and the placement of the climate controls, audio system, armrest and storage just right. We’re also happy to see the instrumentation display incorporate various visual choices, including digital analogue-style dials.

A particular callout goes to the slick and speedy tactility of the brand’s latest touchscreen, as well as the (again suspiciously Toyota-like) interface and graphics layout. It’s all good.

But wait, there’s more. The Outback’s front seats are claimed to be particularly supportive, and after hours in them on and off road, they seem to exceed Subaru’s claims.

If you’re expecting regular mid-sized SUV levels of interior space, be prepared to be impressed, because the Outback’s extra sizing outside seems to be multiplied inside. There’s ample room for long legs, big hats, broad shoulders and buxom hips. It all works so well. This is probably one of the best modern SUV interiors, period. Nothing seems to have been overlooked.

The rear seat is presented to please, too. It can seem a bit drab in the lower-line models, but the same virtues of effortless entry/egress, seat comfort, convenience (including air vents, USB ports, cupholders and armrest placement) apply. We noted the lack of road/tyre noise intrusion at speed, too.

Behind the very sixties Jeep Wagoneer-looking rear is a vast luggage area, complete with a low floor, remote rear-seat folding handles, 12V outlet and quality trim. And that space-saver spare lives underneath.

Subaru seems to have designed this car from the inside out and it shows. A rare 10/10 from us.

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 new K4 sedan is offered in four grades - the base-model S which has an optional 'Safety Pack' available, the mid-spec Sport and Sport+ grades and the flagship GT-Line, which is the model on test for this review.

The GT-Line is sharply priced at $42,990, before on road costs. This positions it in the middle of its small sedan rivals, the Hyundai i30 N Line Premium ($41,500 MSRP) and the Mazda3 Astina ($43,310 MSRP).

What the K4 GT-Line has going for it over its peers is a standard specification list that features some heavy-hitting technology.

This includes dual 12.3-inch displays, a 5.0-inch climate display, built-in satellite navigation with 10-years' of map updates, wireless/wired Apple CarPlay and Android Auto and dual-zone climate control.

Charging is taken care of by two USB-C ports for each row but the front row also enjoys a 12-volt socket and fast wireless charging pad in the dedicated phone cradle.

There's also an eight-speaker Harman Kardon sound system, over-the-air updates, digital radio, AM/FM radio, Bluetooth connectivity, and a 'Sounds of Nature' soundscape for added ambience.

The Kia Connect app is also included and this allows user access to the emergency call functionality (e-Call), remote control functions for the vehicle, as well as vehicle status monitoring.

Premium equipment includes a tilt and slide sunroof with electric sunshade, two-tone synthetic leather upholstery, heated and ventilated front seats, an electric drivers seat (with two-position memory function and adjustable lumbar support) and a heated steering wheel.

For a small sedan, it comes packed with features!

Don’t worry, Subaru traditionalists. The Outback again offers a pair of horizontally-opposed 'boxer' four-cylinder engines.

The regular Outback versions are powered by a 2.5-litre twin-cam petrol unit making 137kW of power at 5800rpm and 254Nm of torque at 3700rpm.

Choosing the Wilderness switches things up to a 2.4-litre turbo version delivering 194kW at 5600rpm and 382Nm between 2000rpm and 3600rpm.

Both use a continuously variable transmission (CVT) with eight artificial ‘steps’ for a more torque-converter-like experience. Sadly, no manual gearbox is available.

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.

Where the Outback regresses compared to its predecessor is efficiency.

Despite a modest 50kg weight rise, the substantially boxier shape is probably behind the jump in petrol consumption, rising nearly one litre per 100km compared to before in the Outback, and nearly 2.5L/100km, in the heavier Wilderness.

The combined average consumption figure for the 2.5-litre naturally aspirated engine is 8.1L/100km, for a carbon dioxide emissions rating of 183 grams per kilometre, while the 2.4-litre turbo manages 9.7L/100km and 228g/km.

Filling the 63L tank, expect an average range of about 777km in the former and just 648km in the latter. Surely, the coming hybrid version can’t arrive soon enough for some buyers.

At least both engines can drink from the standard 91 RON petrol bowser.

So much for the theory. Out in the real world, over a solid day's testing on- and off-road, we found there was a difference of about 1.5L/100km between the regular Outback and the Wilderness.

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.

Confession time. The way the previous Outback drove was profoundly disappointing. The steering felt numb, the ride was too stiff and the car seemed wilfully dull, even in the turbo version.

The contemporary Forester ran rings around it for driving pleasure and refinement.

But Outback number seven is completely different and maybe the best-driving non-WRX Subaru right now.

From the moment you climb on board this vast SUV from Japan, everything feels right – from the driving position and relationship with the controls, to the sumptuously comfy seats and commanding vision all around the vehicle. That’s a promising start.

Push the ignition and press the accelerator down, and the regular Outback 2.5 quietly, gently and smoothly moves off the line. With modest power outputs and a CVT, you might expect it to also sound revvy and droney, but instead the acceleration is strong and throttle responses determined.

We drove this for hundreds of kilometres and never found the performance lacking, even with three adults and their luggage on board, over hilly and even mountainous terrain. Yes, it is possible to have the CVT whining at higher revs, but not within normal driving scenarios. And the quietness and lack of road noise is terrific.

Moving to the Wilderness and its 2.4-litre turbo powertrain, the same applies, except of course mid-range response is significantly faster and with a slicker, more refined delivery. Press and squirt, this is deceptively quick, because the car does a great job in masking the noises and vibrations that working an SUV hard often elicit.

We only wish there was a manual option. With steel wheels, cloth seats and without the Wilderness' add-on gargoyles.

Now, it also seems that Subaru listened and learned from previous criticisms like ours, because the Outback’s newly-redesigned steering is a delight, with a natural, fluent sweetness and ease that’s combined with a pleasing connection with the driver.

The result is balanced, controlled and enjoyable handling, backed up by reassuringly stable road holding. We drove through a sudden, heavy thunderstorm near Bathurst on the first, hot summer afternoon’s test session, and found the Outback to feel impervious through such slippery conditions.

And this all largely applies to the Wilderness as well, though its 20mm-higher ground clearance (to 240mm) makes it feel a little less composed than the glued-down regular model. Both feature a stiffened body and multi-link rear suspension, by the way.

More progress has been made in the Subaru’s ride quality. Gone is the hard suspension feel, for a far-less firm set-up, providing a comfortable and queasy-free ride. Even in the loftier Wilderness. This is the model’s greatest advance over its predecessor and we’re extremely happy with the outcome.

Finally, other than the at-times over-eager driver-attention monitor, the ADAS tech provides subtle, nuanced back-up, with quiet lane-keep intervention, a measured adaptive cruise-control functionality and no jarring buzzes and warnings.

We also enjoyed a session taking both grades off road, to show off their 4WD prowess. The clearances are ample, the hill-descent tech effective and the ability to scramble over wet rocks impressive. The Wilderness especially may even live up to its name!

This is a difficult SUV to fault. The Outback’s breadth of capability on and off the beaten track give it an unusually wide bandwidth for what is a monocoque bodied family convenience. That there is so much sophistication and fun to be had as well make this so much better to drive and live with than the disappointing old version.

We can’t wait to get to know the latest Subaru better on more familiar roads.

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).

The Kia K4 has just been launched and hasn’t been tested by ANCAP yet, so is unrated but Kia is hustling to get it tested so it can join in on their strong five-star performance record. The K4 has seven airbags, including a front centre airbag.

The K4 GT-Line has all of the bells and whistles when it comes to safety equipment and includes the big-ticket items like blind-spot monitoring and collision avoidance, intelligent seatbelt warning (all seats), rear cross-traffic alert, front cross-traffic alert, lane keeping aid, lane departure alert, leading vehicle alert, emergency call functionality, side exit warning, rear occupant alert, traffic sign recognition, driver monitoring and alert, LED DRLs, dusk-sensing LED headlights, front/rear parking sensors and a reversing camera with dynamic guidelines.

The K4 GT-Line has AEB with forward collision warning, car, pedestrian, cyclist, and junction crossing detection.

The rear seat has two ISOFIX child seat mounts on the outboard positions and three top tether anchor points but two seats will fit best.

Kia has become well-known for having annoying sound alerts in their cars and while the K4 has them too - you can easily disable the most annoying one, the traffic sign recognition, by holding the steering wheel volume button in for a few seconds.

Subaru offers a five-year/unlimited kilometre warranty, and that also comes with 12 months of roadside assistance.

Now, that's pretty average nowadays, so nothing special, particularly when other SUV companies like Mitsubishi, Nissan and MG offer conditional 10-year warranties.

Service intervals are at 12 months or 15,000km for both engines. There is a capped-price servicing offer covering this timeframe. They are currently listed at approximately $350, $530, $405, $705 and $370 for an average of $472 per workshop visit.

There are 128 dealers or authorised Subaru service centres across Australia as of January 1, 2026.

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.
