MG HS vs Kia Carnival

What's the difference?

There are a few niggles with the latest MG HS, for example the annoying driver-attention monitoring and expensive maintenance costs. We’ve not had a full sample of its open-road performance yet either, which may prove more telling.

Yet the HS is shaping up to be one of the most successful product updates of recent years, second only to, I don’t know, the MG3? The family SUV is also backed by a 10-year warranty and, despite the drastic improvements, doesn’t cost a whole lot more than before.

The entry-level Vibe is our pick, there's no need to spend more. It features all manner of safety equipment and a quiet drive but with cloth upholstery that doesn't get all sticky and sweaty in the Australian climate.

The end of 2024 is the tipping point where MG goes from cheap and cheerful to a real headache for established players. Perhaps not for the strongest in the segment like the RAV4 and Nissan X-Trail, but the HS is now an easy car to recommend for a family looking for a spacious SUV that drives their dollar further. The hybrid will boost appeal further when it arrives next year.

Ok, here's the rub. Everything you just read could well be pointless. You like the Carnival. In fact, it sometimes makes up close to 90 per cent of the sales in its segment, and outsells all of its competitors combined.

So whether I like it or not, I suspect you'll be buying one anyway.

But I can say this - the new Carnival improves the formula right across the board. Well, everything except for price.

Though the previous HS had shapely bodywork, the wheels sat too far in-board and the rear end looked awkward. It’s not the same story with the new model which is designed as a family SUV first, rather than a converted hatchback platform.

Part of the improved looks are better proportions. The new HS is 81mm longer, 14mm wider and rides on a 45mm longer wheelbase yet sits 21mm lower for a sleeker appearance.

The front end takes cues from the new MG3 and ZS design language with a broad grille and thin LED headlights. At the back, MG’s design team references the UK’s capital with ‘Shard’ lighting signatures that also appear in the alloy wheels.

It is still fairly anonymous, though perhaps that comes from a lack of familiarity with the brand. The painted wheel arch cladding and metallic-only paint give it a premium boost.

The biggest improvement is inside, where the HS takes plenty of inspiration from the excellent MG4 electric car with the hexagonal steering wheel (though here with perforated leather finishing), high-set controls and confident lines. It’s a welcome, modern change after the old car’s bloated cabin design.

There are soft-touch rubbery materials in all sorts of prominent places, including on the dash top, front and rear door cards as well as where the driver’s knees rest on the doors and transmission tunnel.

Surely the greatest trick the Carnival pulls off, and it does so convincingly, is that it manages to make something so quintessentially uncool, the people-mover, and make it look good. Somehow sporty, even.

I like the Carnival's big, bold and blacked-out front end of the GT-Line, and with its two-tone 19-inch alloys, wide stance and low ride height, it looks almost like some mad attempt at a JDM tune car, rather than a sensible people mover.

Elsewhere, the boxy profile, the sharp body creases and the third-row compartment that kind of juts over the rear tyres like a house that's been extended all somehow work, and give the Carnival far more street cred than you might expect.

Inside, we spent time only in the flagship GT-Line and its GT-Line Lite sibling, and both present as calming, comfortable spaces, and Kia's minimalist approach to combining the climate and audio controls into a single strip (it's functionality can be changed by pushing a button) helps keep the cabin fuss free.

The tech in the top-spec models feels modern and on-point, too, and the materials are all nice under the touch. Be warned though, the cabin plastics get progressively worse the further back you sit, and the third row is cocooned by hard and scratchy plastics.

There is nothing especially ground-breaking about the MG HS’s front cabin. The cupholders are medium-sized and the door bins have enough storage for a one-litre bottle, so this is no Skoda Karoq when it comes to clever cabin solutions.

Telling a tale of the HS’s Roewe RX5 base car’s earlier 2022 launch (and the staggering development speed of personal technology) the lack of USB-C charging ports is now frustrating with all USB ports regular old-school items. Apple CarPlay or Android Auto phone mirroring requires a cabled connection.

The centre multimedia screen is high resolution with day selectable light and dark modes. It was a little laggy to use MG’s software, however, especially when swiping across menu screens. 

There are four hard shortcut buttons beneath it that can jump to the home screen, activate the HS’s front and rear demister and turn the ventilation on and off.

To adjust the temperature you need to go into the touchscreen, though there is a persistent shortcut on the main menu.

A 12.3-inch digital cluster has several selectable info displays and can show navigation mapping and directions in Excite and Essence trims. 

The seats are comfortable and supportive and it's easy to find a good driving position thanks to power-adjust driver's seat and tilting/telescoping wheel adjustment. The front passenger does not get height adjust, though, and is set too high.

Where the extra size pays dividends is in the back seat which has ample room for passengers beyond 185cm, especially when it comes to leg space. The fold-out armrest is sturdy, too, with twin cupholders. Rear air vents are fitted to only the top-spec Essence.

For baby capsules or child seats the HS has ISOFIX anchors fitted to all three rear seats matched with a trio of top tether points.

The MG HS’s boot is about average for the class measuring 507 litres. It grows to 1484L with the 60:40 backrest folded. For reference, class leaders include the Toyota RAV4 (580L), Nissan X-Trail (585L) and Volkswagen Tiguan (up to 615L with rear seats slid forward). 

There are few amenities, with no 12-volt socket, only one (dim) boot light and no shopping bag hooks. The carpet isn’t bargain basement and the luggage cover is sturdy with additional separated storage compartments below the floor and netted cubbies off to the side. 

MG has also been smart in packaging a space saver spare tyre beneath the boot floor (and a cumbersome Styrofoam piece).

The Carnival measures 5115mm in length, 1995mm in width and 1775mm in height, and it rides on a sizeable 3092mm wheelbase. 

And those mini-van dimensions have a predictably positive impact on luggage space, with room growing from 627 litres with all seating rows in place, to a massive 2827 litres with the third row stowed.

The key practicality perk here, though, is space, and lots of it. At 175cm, there was ample room for me in the middle row, and you can configure the cabin to your liking, too. You can slide the row on rails, for example, to prioritise leg room where you need it, and the middle seat folds down to reveal cupholders in a kind of hard plastic travel tray.

But even in the third row I could easily get comfortable, though head room begins to get a little tighter. There are cupholders and USB connection points, too, and I can honestly say you could send full-size humans back there and not feel overly guilty about it.

The Carnival will tow 2000kgs braked, too.

Bad news first. The price is higher this time around, right across the five-trim line-up, with the prices up between around $2600 and $5300, depending on which trim level you’re shopping for.

Prices start at $50,150 for the entry-level S petrol, and climb to $72,910 for the top-spec GT-Line diesel. There’s also a GT-Line Hybrid, which tops the group at $76,210, but it’s not here yet, so we’ll cross that electrified bridge when we get to it and stick with the ICE range for now.

The range opens with the S ($50,150 petrol, $52,380 diesel), which scores 17-inch alloys, LED headlights and DRLs, heated mirrors, cloth seats, an electronic parking brake, and a smart key with push-button start, which is new for this update.

On the tech front, there is a new integrated 4.0-inch driver display, and a new 12.3-inch central screen with Apple CarPlay and Android Auto, linking with an eight-speaker sound system, now with a surround-sound function.

Stepping up to the Sport ($56,050 petrol, $58,280 diesel) adds 18-inch alloys, rear LED combination lamps, a leather steering wheel and shifter, and dual-zone climate up front with single-zone temperature control in the second row. New for this update is a wireless charging pad and artificial leather seats. 

Next is the Sport+ ($62,380 petrol, $64,610 diesel), which gets a whole host of new safety equipment, which we will come back to in a moment, along with a powered tailgate, automatic sliding doors and auto windows, and heated seats in the first and second rows. It also ups the tech, with twin 12.3-inch screens taking care of multimedia and driving info duties.

Then comes the GT-Line Lite ($66,350 petrol, $68,580 diesel), which is fitted with bigger 19-inch alloy wheels, scores LED interior lighting, gets a dual-pane auto sunroof and some chrome embellishments on the exterior. The trade-off, though is that the powered windows are now for the driver only, as is the powered front seat.

Finally, there’s the flagship GT-Line ($70,680 petrol, $72,910 diesel), which nabs dual-projection headlights, a heated steering wheel, a 12-speaker BOSE sound system, ventilated seats up front, a big head-up display and a digital rear-view mirror, along with a slightly better interior treatment and the return of the auto window and powered seat to the passenger side of the car.

The new HS petrol has a 1.5-litre, turbo-petrol, four-cylinder engine that develops 125kW at 5000rpm and 275Nm from 3000-4000rpm, with those outputs up 6.0kW and 25Nm on the old car.

MG claims new engine features, including the variable geometry turbocharger, centre-mount variable valve timing and a lighter dual-mass flywheel, add up to a 30 per cent improvement in engine response.

More importantly, the insulation is excellent. You barely hear any unpleasant engine noises out on the road and although the four cylinder’s tone isn’t sexy at full-throttle, it is warm and pleasant enough.

The HS petrol is front-wheel drive only which may rule it out for some buyers, but there is a saving grace. The new seven-speed type dual-clutch transmission behaved itself impeccably on a brief first encounter taking in awkward hill starts and reverse manoeuvres. It’s a huge improvement over prior efforts and more refined than even a Hyundai or Kia dual-clutch.

MG claims a 0-100km/h acceleration time of 9.6 seconds, which is about right for entry-level versions of the HS’s typical rivals.

MG no longer offers a more powerful 2.0-litre turbo but a plug-in hybrid with a punchy 223kW and an all-new full-hybrid option will join the line-up in the first quarter of 2025, details of which are yet to be confirmed.

There are two ICE options on the table here. The first is what I reckon is the lesser of the two, a 3.5-litre petrol V6, producing a rev-happy 216kW and 355Nm.

The better option, I think, is the 2.2-litre, four-cylinder diesel, which makes 148kW and 440Nm, and just suits the nature of the car a little better.

Both pair with an eight-speed automatic, and send their power to the front tyres.

In the ADR combined (urban-extra urban) fuel efficiency cycle, the MG HS petrol is rated at 6.9L/100km, emitting 156 grams of CO2 per kilometre in the process. A 55-litre fuel tank gives the HS a theoretical driving range of around 800km.

We weren’t able to get a true read on the fuel consumption but the trip computer showed 8.1L/100km after an hour-long run. It lacks an idle start-stop system and requires 95 RON premium unleaded petrol.

The petrol engine will sip a claimed 9.6 litres per hundred kilometres on the combined cycle, and produce 220g per kilometre of C02. The diesel lowers both those numbers, to 6.5 litres and 170 grams.

Both models are fitted with a 72-litre fuel tank, which means you’ll be sailing well north of $100 to fill one up.

MG’s launch drive program was too brief to really get under the skin of the HS, which is a shame because the initial signs are extremely positive.

Compared to the old ZS, in which a gumnut hitting the roof was loud enough to distract you from your thoughts, the new car is packed with sound deadening for a vastly more premium experience.

The electronic power steering system has a natural ratio (2.6 turns lock-to-lock) and weighting in 'Comfort' and 'Sport' modes, which cannot be said for rivals such as the Chery Tiggo 7 and Haval H6.

This new HS rides nicely, too, with enough compliance from the suspension without sacrificing body control — at least around town. It has struts up from with a multi-link rear end which is not a given, even in this segment.

There were a few sharp-edged bumps that sent a shock through the body but that is to be expected on Sydney's awful roads. The new HS rides about as well as a Mazda CX-5 and believe us, that is a dramatic improvement.

Visibility out the front and sides are good as is the comfortable driving position, however I wasn’t able to move the driver’s side mirror far enough out for my liking. That’s a small blip in an otherwise strong first showing.

Forgive the horrific paraphrasing, but it seems rumours of the death of diesel have been greatly exaggerated, at least when it comes to the Kia Carnival.

Get this – diesel sales make up some 90 per cent of the Carnival's total haul, with petrol providing a pittance towards the sales total, presumably being picked up by fleet buyers.

And to be honest, that means nine out of 10 people are making the right choice here. Yes, the petrol makes more power, but it's the torque on offer from the diesel that makes pushing the Carnival around feel far more effortless.

The petrol engine can definitely get you moving, but it feels a bit too rev-happy and thrashy when you really put your foot down, and its significantly thirstier to boot.

The diesel isn't perfect – the thrum of the engine is a constant companion whenever you put your foot down, and there's actually too much torque on offer at times, like if you're accelerating up hill from a standstill on a damp road, and so the front tyres can scrabble and scramble for grip.

But it otherwise so perfectly suits the nature of the Carnival that it is definitely the best and most satisfying choice.

Another big change for this update is the fact that Kia's complete ride and handling program has been rolled out here. Kia says local work done on the outgoing car, the one this replaces, was curtailed by Covid and bushfires, and so ended up being done by correspondence.

This one, though, has had the whole enchilada thrown at it, and it shows. They've succeeded in making a bigger car feel smaller around you. It's not a sports car by any measure, but nor does it ever feel too big and unwieldily.

Part of that is down to the steering, which is direct and confidence inspiring, but mostly I suspect it's because of the ride, which is firmer than you might expect in a family hauler, but also offers a connection to that road below that makes you feel in control.

Whether a firm-ish ride is a perk or negative is up to you, but it definitely works for me.

Part of the change package for this updated Carnival is in its safety kit, some of which simply wasn’t available when Kia launched its predecessor.

Which is why every model now gets a centre side airbag, 'Forward Collision Assist AEB', 'Rear Occupant Alert', 'Trailer Stability Assist' and front parking sensors, joining the rear ones that were already there.

Sport+ Models and up now add a 'Blind Spot View Monitor' and rain-sensing wipers, as well as rear AEB through the 'Parking Collision Avoidance' function.

I have to say, though, when your entry-level car is $50k-plus, there’s no real excuse for limiting the best safety kit to the upper-spec models.

Also standard are lane keep assist, with 'Lane Follow Assist', multi-collision braking, a speed-limit warning (which you will turn off) and a reversing camera.

The Carnival range carries a five-star ANCAP safety rating, which it earned in 2021.

MG has recently moved to a 10-year/250,000km new car warranty in Australia which covers the HS and is the longest non-conditional offer in the market.

GWM/Haval, Kia and SsangYong remain at seven years while Mitsubishi requires you to service the car at a main dealer for its 10-year guarantee.

This long warranty period should help allay concerns for new MG buyers that the brand stands behind its products.

Less impressive is the cost of maintenance, which adds up to $2354 over five years/75,000km with a particularly steep $936 service at the four-year mark. There’s a big $1647 service at 120,000km, too.

Like all Kias, the Carnival arrives with a seven-year, unlimited-kilometre warranty, with capped-price servicing throughout.

Kia’s servicing costs are higher than some of its competitors, though, so you might want to compare them, as well as compare what’s included, and the diesel model will usually cost slightly more to maintain than the petrol version.

Service intervals are every 12 months or 15,000kms, and while the brand is still finalising the petrol servicing costs, the diesel prices are $386, $682, $480, $869, $434, $845 and $461, covering the first seven years of ownership.
