MG HS vs Mazda CX-30

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.

About to enter its fifth year in market the Mazda CX-30 is holding up well and this GT SP FWD grade delivers solid value relative to its key competitors, of which there are many. It’s also space-efficient, practical and performs well with top-shelf safety, decent refinement and good dynamic ability.

Alternately, it’s crying out for a hybrid powertrain to improve fuel efficiency, the interior form and function is starting to date and while it meets the market the ownership promise could be sharper. But this little SUV is still worthy of a spot on your new-car short list.

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.

Mazda continues to follow a disciplined design path with everything from the MX-5 sports car to the BT-50 dual-cab ute sharing key attributes like the brand’s signature trapezoidal grille, simple flowing lines and sleek head- and tail-lights, all wrapped up with a subtle hint of chrome here and there.

Car-spotters with the GT SP on their checklist should look out for 18-inch black metallic rims as well as black exterior trim, including the mirror caps. 

Inside, the CX-30 maintains Mazda’s restrained approach with smooth surfaces integrated across the multi-layer dash and primo leather-trimmed seats.

That said, this car is starting to show its age with the multimedia screen plonked on the top of the dash (in typical Mazda fashion) and a largely conventional instrument cluster.

Yes, the main dial is configurable courtesy of a central 7.0-inch TFT screen, but next to more recent arrivals boasting sleek, often twinned, flat screen displays the CX-30 looks and feels out of touch. 

Functionally, there’s a sensible mix of digital controls and physical buttons (points for audio volume and ventilation dials!), but… the multimedia screen can only be accessed by a rotary controller in the centre console once the car is mobile (it works as a touchscreen when you’re stationary).

Some say touchscreens take your eyes off the road so the controller makes sense, but with a sequential app like Spotify it can take a lot of twirls to get to where you want to go, which upsets concentration and takes your eyes off the road, anyway. I’d prefer the relative ease of a quick press on a screen.

Aside from all that, the materials used are high quality with soft-touch surfaces across key contact points and hard plastics confined to high-wear areas. 

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).

At just under 4.4m long, close to 1.8m wide and little over 1.5m tall (with a 2655mm wheelbase) the CX-30 is in the middle of the pack it competes with in terms of key dimensions.

And space up front is more than adequate, with an impressive feeling of roominess for a relatively small SUV.

For storage, there’s a large lidded box (which doubles as an armrest) between the front seats as well as a pair of cupholders in front of the gear-shifter with a bay for wireless device charging ahead of that.

The glove box is big, there are bins in the doors with room for decent size bottles and a drop-down tray for sunglasses sits overhead.

Move to the rear and the amount of space on offer is surprisingly generous. Sitting behind the driver’s seat, set for my 183cm position, I have plenty of head and legroom, although three full-size adults across the back seat will be an uncomfortable proposition for anything other than short trips. A trio of up to mid-teenage kids will be fine.

Adjustable air vents at the back of the front centre console are a welcome inclusion for back-seaters and storage runs to a map pocket (weirdly, on the back of the front seat only), a pair of cupholders in the fold-down centre armrest and bins in the doors with room for smaller bottles.

In-cabin power and connectivity includes two USB-C outlets and a 12-volt socket in the front centre storage box. No USBs specifically for those in the rear, which is a miss for road trips and no 12V in the boot which can be handy when camping or picnicking.  

Speaking of the boot, cargo volume with the rear seat upright is okay for the class at 317 litres, which expands to a healthy 1479L with the 60/40 split-folding backrest lowered. For comparison the Kia Seltos coughs up 433L with the rear seat upright.

The space is illuminated, there are tie-down anchors to help secure loose loads and there’s a space-saver spare sitting under the floor.

And if you’re keen on towing a tinnie or similar you’re good to go for a 1200kg braked trailer (600kg unbraked).

The Mazda CX-30 G25 GT SP FWD weighs in at $43,140, before on-road costs and our test example features the optional ‘Vision Pack’, the details of which we’ll get to shortly, raising the price $1300 to $44,440. 

Alternate options around that price point include the Hyundai Kona Premium N Line 2WD ($42,500), Kia Seltos GT-Line FWD ($41,850), Mitsubishi Eclipse Cross Exceed 2WD ($40,990), Honda HR-V e:HEV L 2WD ($42,900, drive-away), Nissan Qashqai ST-L FWD ($42,690), Peugeot 2008 GT FWD ($44,490), Renault Arkana Techno FWD ($41,000), Suzuki S-Cross Plus FWD ($41,490), Toyota C-HR 2WD GXL Hybrid ($42,990) and Volkswagen T-Roc Style FWD ($40,590).

That’s quite the automotive smorgasbord, the resulting price and specification cage fight meaning every included feature counts and the Mazda heads into battle with some significant weapons in hand.

Specifically, dual-zone climate control, a head-up display, a 10.25-inch ‘widescreen’ multimedia display, 7.0-inch driver’s multi-information display, 12-speaker Bose audio (with digital radio), wireless Android Auto and Apple CarPlay, ‘Burgundy’ leather seat trim, heated front seats, leather trim on the gearshift and heated steering wheel, wireless phone charging, power-adjustable driver’s seat (with memories), a glass power tilt and slide sunroof and a power tailgate.   

There’s also adaptive auto LED headlights, 18-inch black metallic alloy wheels, radar cruise control (with stop/go), a reversing camera, auto-fold (and tilt) heated exterior mirrors and keyless entry and start. 

It’s an impressive and competitive equipment list for a small SUV under $45K, even before we get to the performance and safety tech covered later in the review.

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.

The CX-30 GT SP is powered by a 2.5-litre, naturally aspirated, four-cylinder petrol engine producing maximum power of 139kW at 6000rpm and peak torque of 252Nm at 4000rpm.

It’s a proven all-alloy unit featuring direct-injection as well as variable intake and exhaust valve timing with drive going to the front wheels via a six-speed auto transmission. 

The AWD version of the GT SP adds an electromagnetic multi-plate clutch pack (managed by a multitude of sensors) to selectively engage the rear wheels, as well. But its engine and transmission combination is identical to this FWD model’s.

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 CX-30 GT SP FWD’s official fuel consumption figure on the combined (urban/extra-urban) cycle is 6.6L/100km, the 2.5-litre atmo four-cylinder engine emitting 154g/km of C02 in the process.

It features fuel-saving stop-start and cylinder deactivation functions as standard and over a combination of city, suburban and some freeway running we saw an average of 8.4L/100km, which is average for an SUV in this class. A comparable hybrid package would easily better this result.

Based on the car’s 51-litre fuel tank theoretical range between refills is 772km, which drops to just over 600km using our real-world test consumption number. But the good news is this CX-30 runs happily on cheaper 91 RON ‘standard’ fuel.

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.

It’s rare in 2024 to find a small SUV that doesn’t have at least one turbocharger attached to its engine, the CX-30’s 2.5-litre ‘atmo’ four being one of those increasingly scarce examples.

But Mazda’s been laser-focused on extracting maximum power and efficiency from its non-turbo petrol engines for yonks and this one stands up well.

It doesn’t have the low-down punch a turbo typically delivers but maximum pulling power arrives at a useable 4000rpm and it’s eager enough for easy city and suburban running as well as confident freeway cruising.

Although Mazda doesn’t quote an official number you can expect a sprint from 0-100km/h in around 8.5 seconds, which is quick for the class.

Worth noting engine noise and a raspy exhaust note make their presence felt under acceleration and the throttle isn’t as refined as it could be. Not a huge deal, but a slight jerkiness is evident on initial, especially moderate, acceleration.

The six-speed auto is smooth and fuss-free, the steering wheel paddle shifters on hand if you need to intervene and select a specific ratio. ‘Sport’ mode peps things up, causing the transmission to shift down earlier and up later. But it’s aggressive in that it often holds onto a gear for too long and you find yourself diving back to the default normal setting.

Tipping the scales at just under 1.5 tonnes, the CX-30 is underpinned by a MacPherson strut front, torsion beam rear suspension and ride comfort on typically pock-marked urban surfaces is average for the category. That is, a bit jittery over bumps and corrugations but there’s no bone-jarring going on here.

Steering feel and response is good and the grippy steering wheel helps with a connection to the front tyres. Speaking of which, the standard rubber is high-performance (215/55) Dunlop SP Sport Maxx 050 which is  grippy and commendably quiet. 

Push on into a corner and the CX-30 remains balanced and predictable with body roll well under control. Torque vectoring, by engine and physical braking, is also onboard to reel things in if you overstep the mark.

Braking is by discs all around, vented at the front and solid at the rear, and they wash off speed effectively with a satisfyingly progressive pedal action.

Vision is good, which combined with the CX-30’s compact dimensions and 10.6m turning circle, means parking is easy. Especially when you factor in the hi-res reversing camera and front and rear parking sensors. 

The CX-30 carries a maximum five-star ANCAP assessment from early 2020 when the car was introduced locally.

It scored a stunning 99 per cent in the adult occupant protection category and an impressive 88 per cent for child occupant protection.

Active (crash-avoidance) tech includes AEB (operating from 4.0-160km/h) as well as lane keep assist, lane departure warning, traffic sign recognition, intelligent speed assistance, blind-spot monitoring, front and rear parking sensors, rear cross-traffic alert, a reversing camera and tyre pressure monitoring.

Mazda’s ‘Vision Pack’ is also standard which includes a 360-degree camera view, ‘Cruising & Traffic Support’, driver fatigue monitoring and front cross-traffic alert.

The airbag count runs to seven - dual front and front side, full-length side curtains and driver’s knee.

There are three top tether points for child seats across the second row with ISOFIX anchors on the two outer positions.

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.

Mazda covers the CX-30 with a five-year/unlimited km warranty which is the norm in the mainstream market, and it’s worth noting a growing number of competitors are now at six, seven or even 10 years, although the latter are typically conditional on authorised dealer servicing. Roadside assistance is provided for the duration of the warranty.

Service is recommended every 12 months or 15,000km and Mazda’s ‘Service Select’ program sets maintenance pricing out to seven years, the lowest over that period being $352 and the highest $626, for an annual average of $459, which is reasonable but not exceptional for the category.

For comparison, a similarly specified Toyota C-HR averages $330 per workshop visit over the same period.
