Kia K4 vs MG MGS5 EV

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.

Benchmark is a big word. But I’ve been testing cars long enough to know when and where to use it, and if my motoring instincts are correct the MG S5 EV could be the new benchmark for budget small electric SUVs.

Still we’ve only driven one grade - the Essence with the bigger 62kWh battery. We need to get the other grades into the garage to test them too, but on first impressions the MG S5 is outstanding for price, practicality, styling, ownership, and the way it drives.

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 MG S5 EV is a completely new car. Unlike the ZS EV which was a combustion car that was later turned into an EV, the S5 EV was designed from the start and built as an electric vehicle and that’s super important for everything from space to how it drives.

The S5 EV is a bigger car than the ZS EV. It’s 153mm longer and 40mm wider and it shares the same underpinnings as the excellent MG4 hatch.

The S5 EV looks a bit like the MG4 but an SUV version and I think the styling is a massive improvement over the ZS EV. This thing looks snatched with its sleeker shape and a smooth modern face, the blade-like LED running lights sitting atop the headlights and I really like the treatment to the tail-lights as well and the way the boot lid flicks up into a little integrated spoiler.

It's a far more refined, mature and prestigious look to the ZS EV. And while we're being completely subjective here I also think it's better looking and more refined than the BYD Atto 3 and Chery E5.

That same refinement and modernity is everywhere in the superb cabin from the clean dash design and door trims, to the steering wheel and floating centre console.

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 MG S5 EV’s practicality is also outstanding and while it’s early days, it could be the new benchmark for the class. It's a spacious cabin with superb ergonomics and excellent storage.

Even as a taller person (I’m 189cm) there was plenty of elbow, shoulder and legroom for me as a driver and also to sit behind my driving position in the second row.

Storage is excellent with giant bottle holders in all the doors, stowage under the floating centre console, four cupholders and a flat space for your phone which also is a wireless charger on the Essence.

It’s such an ergonomic and practical cabin even the buttons are practical. There’s a volume dial, and physical buttons and switches for the climate control switch, not screen buttons.

And then there’s the boot, at 453 litres it’s about 10 litres bigger than the ZS EV’s cargo capacity. It's also 10L larger than the Atto 3 and a lot bigger than the Chery E5’s boot.

There are two grades in the MG S5 EV line-up. The Excite is the entry grade and the Essence is the top-of-the-range grade. Both come with a choice of two batteries - there's the smaller 49kWh battery and a bigger 62kWh battery. Now that you know this, the pricing will make more sense.

The MG S5 EV line-up starts at $40,490 with the entry grade Excite with the 49kWh battery, then steps up to $42,990 for the Essence also with the 49kWh battery. That increases to $44,990 for the Excite with the 62kWh battery and tops out at $47,990 for the Essence with this unit. All prices are drive-away.

Standard features on both the Excite and Essence include LED headlights, LED running lights and LED tail-lights, also standard are alloy wheels - 18-inch ones on the Essence and 17s on the Excite.

Both grades have proximity unlocking single-zone climate control, a 12.8 inch media display digital radio, a four-speaker stereo on the Excite and a six-speaker sound system on the Essence, while both have wireless Apple CarPlay and Android Auto, sat nav and a 10.25-inch instrument cluster.

The Essence has a few extra items the Excite doesn’t get like rear privacy glass, a panoramic glass roof, wireless phone charging, heated front seats and a power driver’s seat.

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 MG S5 EV has one electric motor driving the rear wheels and it has an output of 125kW and 250Nm. That’s plenty of grunt to move this electric car quickly and instantly in a way that feels controllable and smooth. 

While front-wheel-drive cars are absolutely fine, rear-wheel drive tends to offer more engagement and feel, and that's an added bonus for the S5 EV.

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 MG S5 EV’s energy consumption varies depending on the grade and battery size.

The most efficient in the range is the entry grade Excite with the 49kWh battery with MG saying on a combination of open and urban roads it should use 16.6kWh/100km (WLPT). The biggest energy user in the range is the Essence grade with the 62kWh battery with 17.1kWh/100km.

As for the range, this varies from 335km in the 49kWh Essence to 430km in the 62kWh Excite.

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 MG S5 EV is outstanding to drive for an electric vehicle at this affordable price point. Again, I’m going to put it out there and suggest it could be the new benchmark for the more affordable end of the small electric SUV segment. Kia's EV3 is also a winner on the road, but it's quite a bit pricier than the MG.

I was never a fan of the way the ZS EV drove, from its seating position to ride and handling. But the MG S5 EV is completely different to pilot. It’s excellent.

This car feels so composed on the road, the body control is excellent, the steering is well weighted and direct, the visibility is excellent and the pedal feel under my feet is solid, too. And all of that is combined with an electric motor that makes the perfect amount of power.

Add to all this the rear-wheel-drive component and the MG S5 EV is not just easy to drive but engaging as well.

The MG S5 EV has the maximum five-star ANCAP rating and that’s from 2025 so it is super fresh. That means it has the lot so there’s auto emergency braking (AEB), front cross-traffic alert, rear cross-traffic alert with braking, lane keeping assistance and blind spot warning, adaptive cruise control, intelligent speed limit assist and more.

There's also a driver and front passenger airbag, two side airbags, two curtain airbags and a far side airbag.

For child seats there are two ISOFIX points and three top tether anchor 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.

The MG S5 EV is covered by MG’s 10-year 250,000 kilometre warranty. And that includes the battery. Regular families though do about 10,000km a year or 20,000km maximum, so this warranty offers excellent coverage for them.
