MG MG5 vs Kia K4

What's the difference?

The MG5 works well as a budget-friendly small car, and it’s genuinely good to drive.

Some small let-downs in terms of packaging don’t detract from this car in any major way, but the lack of active safety is a concern considering the features most of its rivals offer.

If it’s on your shopping list, make sure you know what else is on offer in terms of safety before you lock in the MG5 for the savings.

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 MG5’s styling might be a little divisive, with the overall shape and look of the small sedan sitting somewhere between its direct rivals, like the Hyundai i30 Sedan, and aspirational models like the Mercedes CLA.

In this Essence variant, the grey insert for the grille gives the front a darker, more aggressive look, though the way the grille mesh weaves makes it look a little like moustache hair.

The large ‘intake-style’ design at the sides gives it a sportier look than its outputs have perhaps earned - not to say the MG5 is sluggish - and following those around to the side of the car leads to a fairly minimalistic and tidy silhouette.

Here, probably most notable is the rather tall gap between the tyres and wheel arches.

The rear, with that sloped-up roofline, transitioning into a gentle lip spoiler, flanked by those lights, is where CLA fans might have the most to say about the MG5’s design.

Notably, the exhaust vents at the bottom are fake. The real exhaust exit is hidden well underneath.

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. 

Some newer brands to Australia, often MG’s compatriots from China, get some of the ergonomic or tech basics wrong as they focus more on an impactful first impression. Fortunately, MG doesn’t do that, for the most part.

Inside the MG5 is a cabin that looks more expensive than it is, but has some useful features to back it up without the superfluous add-ons.

Aside from the lack of physical climate controls - an annoying cost-saving or interior-tidying trend embraced by brands from budget to bougie - the MG5’s interfaces and ergonomics are pretty sensible.

Accessibility ticks for the steering wheel buttons being few and large enough to use without needing to look, as well as the lack of a panel of buttons and switches in the centre console. Looking at you, BMW.

The screen is also functionally sound, with obvious menu layouts and fairly large buttons as touch points, so it doesn’t feel like trying to operate a tablet while you’re driving.

It does, again, lose points for the climate control situation, which weirdly features a temperature slider as a colour gradient rather than numerical temperatures.

No wireless phone charger means needing space for a plugged-in phone, which the MG5 has just enough of, though similarly ‘just enough’ is the size of the cupholders, which won’t fit a big water bottle.

In the rear, there’s space enough for an adult to sit comfortably behind another adult, though it’s not the place for long journeys.

Strangely, there’s only one central vent control in the rear so only one passenger gets cool air or heat, plus there isn’t a great deal of storage. No armrest or cupholders for rear passengers, either.

Also noteworthy is the single-piece rear seat, which means if longer items need to be transported in the 401-litre boot, the whole rear seat must be folded down and the MG5 temporarily becomes a two-seater.

Under the boot floor is a space-saver spare, though, so bonus points for a more useful addition than a simple repair kit.

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!

Both versions of the MG5 come with a 1.5-litre four-cylinder engine that drives the front wheels, but the similarities mostly end there.

In the entry-level Vibe, that engine is naturally aspirated and makes 84kW and 150Nm - similar to the MG3. Power is transferred to the front wheels via a continuously variable transmission (CVT).

In our Essence variant the engine is turbocharged and makes a suitably higher 119kW and 250Nm, driving the front wheels via a seven-speed dual-clutch automatic transmission.

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 naturally aspirated Vibe's official combined cycle fuel economy figure is 5.7 litres per 100km, while the turbocharged Essence drinks a little more at 5.9L/100km.

For comparison, Toyota claims its non-hybrid Corolla Sedan will sip 6.0L/100km, while a Mazda3 Sedan claims 6.1L/100km. Not bad, then, if you can keep it near MG’s claim.

During our testing, with a mix of city, suburban, highway, and rural driving, the MG5 Essence burned through 95 RON premium fuel at a rate of 9.1L/100km, checked at the pump, though I wouldn't expect this to be representative of normal, calmer day-to-day driving.

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.

Perhaps the biggest surprise about the MG5 is that it’s quite good to drive. And not just ‘for an MG’ or ‘for a car from China’. It’s actually good.

The turbocharged engine takes a moment to get going, and the dual-clutch can be a little hesitant off the mark.

The combo of the two means sometimes you need to plan your take off ahead of time - but in its above-3000rpm sweet spot, the Essence has a good bit of urgency to it.

That’s fortunately paired with a combination of comfortable suspension and a composed chassis, with well-weighted steering.

On urban roads and with a little awareness of the slow take-off, the MG5 is capable and well-suited to small roads, though it can be a little frustrating in stop-start traffic.

On the other hand, outside the confines of city driving, the small sedan is more dynamic than you might expect, able to get up to speed and comfortably overtake on highways, as well as handle corners on twisty roads confidently.

Potholes and rough sections of road don’t rattle the MG5 as much as you might expect from a car in this segment, though road noise can be a intrusive on coarse roads - of which Australia has many.

Dare I say it - the MG5 is rather fun.

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.

MG offers a seven-year/unlimited kilometre warranty on the MG5 as with all its models - even electric cars. That also comes with roadside assist for the duration of the warranty, though only 160,000km is covered by the warranty if the car is used for commercial purposes.

Servicing prices for the MG5 range from $266 or $272 for the Vibe or Essence, respectively, up to $581 or $661 for the most expensive of the seven 10,000km/12-month scheduled services.

The total cost of servicing the Vibe over its seven years under capped-price servicing comes to $2661, or about $380 average per service. For the Essence, that bumps up to $2764 or an average of about $394 per service.

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.
