MG ZS vs Kia K4

What's the difference?

The MG ZS Essence with the 1.5-litre petrol engine has many strengths - price and value for money, practicality and space, good looks… and the only area where it really struggles to match its rivals is its underpowered engine. 

The good news is the Essence also comes with a turbo engine and while this isn’t a race car by any means, turbocharging is a way to add the oomph needed in a car this size. 

Stepping up to the MG ZS Essence Turbo costs an extra $2000, but if you can make the budget stretch you’ll have the complete package of value, looks, practicality, safety and much better performance for more enjoyable driving.

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 ZS's good looks is another strength.

The new-gen ZS arrived in Australia late in 2024 and this petrol version landed in February 2025. The styling looks more expensive and premium than its price tag would suggest. The sleek nose, the refined tail-lights, a pleasing profile all make for a good looking small SUV.

There are many interesting elements in the design - the grille and its aggressively looking flanking 'air intakes', the crease through the door panels, the little fin that meets the tail-light.

Squint and it looks like a mini Ford Territory. Sort of…

The cabin of the ZS Essence is equally refined with a modern design and soft touchpoints throughout. It’s a minimalist and spacious place free from button clutter.

The ZS is 4430mm long, 1818mm wide and 1635mm high. Ground clearance is 161mm, in case you’ve been lying in bed wondering.

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. 

Practicality is a big strength, too, with a proximity key that’ll unlock the car when you touch the door handle, and a cabin with good legroom and headroom even for me at 189cm tall.

There's also a wonderfully simple charging pad for your phone - it's a large area on the centre console which works well in terms of connection but also in terms of wasy access. Many rivals will hide phone chargers away is small crevices that make them hard to extract or even pop in.

You'll find four USB ports, too plus a 12V charger, too.

Clever storage like a shelf built into the dash for loose objects, four cupholders and big door pockets are also on hand.

The boot is also a decent size for a small SUV at 443 litres which is bigger than many rivals, including the Subaru Crosstrek.

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!

Okay, we've listed a lot of strengths for the MG ZS but the engine isn’t one of them. The 1.5-litre four-cylinder petrol engine makes 81kW and 140Nm.

Really, power needs to be at least 100kW and torque closer to 200Nm in something weighing 1330kg otherwise acceleration is going to feel woeful - which it is.

Seriously, the first time I tried to overtake I looked down to see if the handbrake was still on.

Not helping performance is a CVT (Continuously Variable Transmission) which, while good for fuel economy, seems to have trouble getting power to the road effectively.

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.

Official fuel consumption for the combined (urban/extra-urban) cycle is 6.7L/100km, which isn’t outstanding, especially compared to the hybrid version which can get 4.7L/100km.

Our own testing after city driving and motorways saw 7.9L/100km. Not the most efficient engine in the range, so if it’s saving petrol you want then go for the hybrid, or better still, the electric version of the ZS.

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.

The lack of oomph from the 1.5-litre naturally aspirated four-cylinder engine affects the driving experience of the ZS. This lack of accleration is hampered not just by the low outputs of the engine but also by the transmission, which is a CVT and these don't favour getting power to the road as effectively as torque convertor transmissions.

Handling is good for this class, with the ZS feeling stable under most conditions. Steering is excellent, with a nice weight and accuracy to it.

And while the ZS is no prestige car, the ride is comfortable, composed and better than many small SUVs at this price point.

Other pluses include its smaller size which makes it easy to manoeuvre in city traffic and park in tight spaces.

The final driving score however is dragged down by the engine and transmission which fail to provide the acceleration needed to easily overtake, merge or move quickly when needed at stop signs or out of car spaces on busy 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.

Ownership costs are a strength, too. The MG ZS is covered by a 10-year/250,000km warranty.

MG’s ‘Precise Price’ service plan locks in the cost of servicing with 12-month/15,000km intervals and a cost of about $1200 over five years.

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.
