Volkswagen Polo vs Kia K4

What's the difference?

The VW Polo may be getting old, but it still shines on a number of fronts, including design, interior packaging and presentation, driving sophistication, efficiency and quality.

But, the ride can be too firm and the turbo/DCT lag frustrating, it is also expensive and not fully equipped enough in CityLife grade as tested, undermining the German’s value-for-money equation somewhat.

Haggle hard, though, and you’ll end up with a fine and mature urban hatch.

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.

Still looking good after nearly a decade, the 2026 Polo’s styling was overseen by the same person who created the landmark Mk4 Golf’s interior, and helped shape every existing ID. electric vehicle (EV) in VW’s arsenal, though now he’s with Changan of China.

Anyway, Polo 6’s dimensions were substantially larger than its pert predecessor’s, riding on a shortened Mk7 Golf platform (dubbed MQB A0) that has since also underpinned the very closely related Audi A1 (the circle of life!) and Fabia, as well as Skoda’s Kamiq light SUV and its VW T-Cross cousin.

The obvious upshot of all this growth is generous cabin space (being roomier than the first four Golfs), as well as a very Golf-esque/ID. EV-style dash layout that's inline with the brand’s existing design themes. It pays to be first with the new stuff. Even though some of that tech, like the touchscreen slide controllers and other buttonless nonsense developments, have taken the shine off VW since.

And it would be remiss of us not to mention that there is no sign of the current Polo being retired anytime soon despite its advancing years, with VW suggesting the newly unveiled ID. Polo EV – essentially series number seven – will run alongside with identical dimensions but far greater interior space, to help keep the company cost-competitive in the light-car class.

At this stage we don't know if Australia will even receive the new electric Polo, so the status quo here remains.

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. 

The Polo features classic light-car proportions, but typical VW touches largely elevate the experience compared to most rivals.

For starters, because it’s German (though built in South Africa), everything feels high quality, even down to the harder lower-set plastics. Contrasting textures, soft cloth and glossy trim really up the ante. Care has obviously been taken here.

Likewise, the front seat area has been designed to easily accommodate people upwards of two metres tall. Just don’t expect much legroom behind. And the driver’s seat can be set ultra low.

Entry/egress is fine, on typically firm-ish yet highly supportive front seats, as evidenced by a four-hour weekender trip away.

The driver is sat ahead of a solid, stylised console angled slightly for a heightened connection to the car, aided by an excellent operating position offering ample reach/rake steering adjustability. Most people should settle in very nicely behind the handsome wheel here. Vision is fine but many competitors do offer deeper side windows for better sightlines.

The updated multimedia system at last brings a volume control, the touchscreen is positioned high for easy access, with crisp graphics and instant responses, and the switchgear have a quality feel to them. And while CityLife’s climate-control slider actuators are nobody’s favourite, this one works as intended. Cheaper grades have basic dials.

Smallish twin cupholders won’t please American-sized drink-holder expectations, but otherwise the Polo’s storage options are plentiful and generous. So is the ventilation output and reliable wireless connection for the Bluetooth phone and Apple CarPlay media, never dropping out once during our entire trip.

Rear-seat room is down basically to how far back the front seats are, but for a car of this size the Polo’s more than fine.

A sufficiently comfy backrest and fixed, sculptured cushion mean this isn’t misery, aided by another helping of the appealing material finishes found up front, as well as the extra side window that makes it feel a little bit airier than many others. And while there are no face-level air vents, the large dash outlets provide enough flow through.

But the lack of a centre armrest means there are no cupholders, so occupants must rely on the (albeit deep) door pockets. At least VW bothers to provide two USB-C ports, a pair of map pockets and big, grippy door handles as a make-do.

Finally, the easy-to-load and quite hungry boot area is big for such a small car and some 25 per cent larger than the previous Polo, offering from 351 litres with the twin backrests in situ to 1125L dropped, and that’s with a space-saver spare wheel underneath the floor.

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!

The 85TSI is a 1.0-litre three-cylinder turbo-petrol engine, with direct injection and a start/stop system designed to save fuel.

That said, this EU6 emissions-rated unit provides a healthy 85kW of power between 5000-5500rpm, as well as 200Nm of torque from 2000-3500rpm.

It drives the front wheels via a seven-speed dual-clutch transmission (DCT) VW brands DSG, while other markets enjoy the option of a six-speed manual.

The official 0-100km/h acceleration time is 10.4 seconds, on the way to a top speed of 200km/h.

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 EU6-rated Polo’s ADR 81/02 lab-tested average combined fuel consumption figure is 5.4 litres per 100km, for a carbon dioxide emissions average of 123 grams/km.

Brimming the 40-litre tank with premium unleaded petrol (95 RON minimum is recommended) should result in about 740km between refills.

We managed a respectable 5.9L/100km driving over 605km with the distance-to-empty still showing 85km remaining, while the trip meter’s long-term average read 6.1L/100km.

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.

It is quite astounding how VW manages to maintain a consistency throughout its model range, from Polo to Touareg, and the CityLife’s 85TSI DSG is no exception.

Press the starter button and you’ll barely discern the engine as a three cylinder, so effective is the sound deadening. Slot the satisfyingly normal gear lever into ‘D’ and, depending on your expectations, what comes next seems either a tad frustrating or impressively lively.

Let’s explain this more.

As with almost all turbo/DCT applications, there is a moment’s hesitation due to the turbo spooling and gears meshing up. If you’re rushing to merge with fast motorway traffic or turning at an intersection, the acceleration can feel like it needs forever before the car lurches into action and you’re on your way. Every single time.

Yet, in every other circumstance, the 85TSI is a lusty and lively machine, stepping away eagerly and smoothly under moderate throttle input, with the speed then instantly piling on as the engine’s revs reach towards the 5000rpm sweet spot, accompanied by a throaty exhaust note.

Combined with the ultra-fast ratio changes that the DCT is famous for, this is when you’d call the Polo enjoyably rapid, offering instant response for quick and easy overtaking. And all the while, the powertrain feels and sounds silky-smooth.

We noted that the adaptive cruise control betrays the VW’s age, since it can maintain varying speed with traffic flow, but once fully stopped, it requires the driver to keep a foot on the brake pedal to keep it from releasing and creeping forward (or backward on a hill). Nowadays, most newer systems stay stopped until traffic moves on again. It’s a surprise that the company did not update this with the Polo’s 2022 facelift.

The steering, though, feels state-of-the-art. A real treat, it is precisely weighted and beautifully tactile, for immersive, controlled cornering agility and feel over an impressively broad range of speeds and environments.

On smooth roads the 85TSI’s dynamic fluency is lovely, with the front end working with the keen driver while also providing reassuring grip and control. Yet it’s also light and easy enough to fit in tight spots, or zig-zag through traffic, making it an ideal urban runabout.

After a seemingly endless run of (especially Chinese) EVs and hybrids serving up dull and detached steering, the Polo’s nuance and finesse is a total breath of fresh air. VW, please don’t lose this ability.

The same also applies to the advanced driver-assist systems (ADAS) tune, which works quietly yet effectively in the background without jarring interference. The Polo feels light years ahead here as well.

But a bit more suspension comfort is required when the roads get rough.

Isolating and cushy on the smooth stuff to the point it feels like a luxury car, the suspension starts transmitting bumps and lumps when the bitumen turns bad, breaking the seamless flow of an otherwise accomplished chassis tune. It can also become a bit vocal over coarse bitumen, due to road and tyre noise intrusion.

Otherwise, the 85TSI is a slick and accomplished drive, with a quiet ride and long legs for easy, long-distance cruising.

Just like every other new VW.

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.

The Polo comes with an industry-standard five year/unlimited kilometre warranty, as well as one-year’s free roadside assistance.

This can be extended annually if serviced at a VW dealer. Service intervals are 12 months or every 15,000km.

VW also offers a pay-as-you-go capped-price servicing program. For 2026, prices have been reduced over the previous year, coming in at $425, $681, $407, $1037 and $407 at the time of publishing.

Alternatively, buyers can prepay for a three or five-year service pack to save a bit more money. Three years costs $1507 and five years is $2799.

Note, however, that a Toyota Yaris SX Hybrid equivalent costs about $250 annually to service, or around $1250 over five years.

Finally, there are about 100 dealers or agents throughout Australia offering servicing and mechanical repairs.

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.
