MG ZST vs Mazda CX-30

What's the difference?

Will the MG ZST Essence fit a small family? Absolutely, and all but the middle seat passenger will be comfortable but there are areas open for improvement. Like it's safety, laggy tech and adding a few extra items in the back seat.

Yet, it still offers a good host of features and an attractive package for a reasonable price tag. Unfortunately, my son missed having the basic amenities but did like the sun roof.

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.

Being the newer and shinier version of the ZS, the ZST presents as a nice little package with its full suite of LED exterior lights, shiny chrome accents and its well-shaped body.

The front is distinctively different from its design muse with a darkened grille, and redesigned fog lights that feature new air intake vents. Other highlights include the 17-inch two-tone alloy wheels with sporty red brake calipers lurking behind them.

The interior is pleasant with a massive sunroof creating a light-filled space and giving the illusion that the cabin is larger than it is.

The synthetic leather upholstery and trims seem robust and perfect for families, but also feel quite plasticky under hand. The red badge embossing on the headrests is lovely, though.

The dashboard is well-proportioned and headlined by an upgraded 10.1-inch touchscreen multimedia system and fully digital instrument cluster.

The gearshift feels a tad too skinny and tall for the general aesthetic but the circular air-vents add some cute personality.

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. 

Practicality is hurt by a lack of individual storage options and a back seat that has only two USB-A ports for its amenities.

The cabin space is spacious, though, and both rows have a decent amount of leg- and headroom despite the massive sunroof.

The steering wheel features height but not reach adjustment and to accommodate I have to sit much closer to the wheel than normal thanks to my poor little T-Rex arms.

Individual storage is the best up front with a small middle console and glove box, two cupholders and two drink bottle holders. The doors also feature large storage bins, which is great to keep the cockpit feeling neat.

The rear row gets two map pockets and a small storage bin in each door. There is also a (very) shallow storage nook at the back of the middle console… think a packet of gum or small wallet size.

My seven-year old isn't as comfortable in the rear because it lacks directional air vents, reading lights and a fold-down armrest. All items which will hinder an adult's comfort, too.

The boot space is a good size at 359L but you can bump it to 1187L with the rear seats folded, the backrest featuring a 60/40 split.

The height of the floor is adjustable and when set in the lowest position creates a deep well to tuck larger items, like luggage, into.

The hard cargo cover can be awkward to shift around or store but is otherwise out of the way when it counts.

Other amenities accentuate the premium-feeling the Essence is going for with the heated front seats and electric drivers seat offering well-padded comfort but on longer journeys, I miss having adjustable lumbar support.

The rear seats aren't as comfortable as the front only because the synthetic leather feels slippery, which is accentuated when you hit corners!

In terms of technology, you get two USB-A ports in each row but the front also gets a 12-volt port. You miss out on fast and wireless charging options.

The multimedia system looks great but can be sluggish to respond and the apps can be slow to load but I like the built-in satellite navigation.

The upgraded sound system has six speakers instead of four but the sound quality is a bit tinny with music and calls.

It was simple to connect to the wired Apple CarPlay. It also has Android Auto, Bluetooth connectivity and AM/FM radio.

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 Essence variant has a 1.3-litre, three-cylinder turbo-petrol engine with a maximum power output of 115kW and 230Nm of torque.

It's a front-wheel drive and features a six-speed auto transmission. Overall, it has enough power to keep up with traffic on the open road but you have to be firm with the accelerator to keep your speed consistent.

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.

The official combined cycle fuel figure is 7.3L/100km and my real-world average came in at 7.7L. That is after a good mix of urban and open-road driving, so the usage is good.

Based on the combined fuel cycle and the relatively small 45L fuel tank, expect a driving range of around 616km.

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.

The ZST Essence has an okay amount of power relative to the car's small size.

It's an adequate cruiser when I ferry just my husband and son around, but feels a full load of luggage and people.

The steering is responsive and it's an easy car to manoeuvre in tight car parks or city streets, which is great. The visibility is pretty good despite the chunkier pillars and you feel confident when checking your blind-spots.

While the suspension is fairly forgiving and ride comfort is decent, you will still notice the bumps, especially when seated in the back.

The cabin suffers from some wind and road noise and at higher speeds we had to find we raise our voices a bit to be heard. Around town, you don't notice it.

This is just a personal preference but the brake and accelerator pedals are skinnier and more centrally positioned than I prefer. You get used to it, though.

The ZST is pretty easy to park and it's great that you have a 360-degree camera system but the image quality can be grainy. You get rear parking sensors, too, but miss out on ones at the front.

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.

The ZST Essence comes with a seven-year/unlimited km warranty, which is on par with coverage offered by a growing number of its rivals.

There is a seven-year or up to 70,000km servicing program for a total cost of $2339 or an average of $334 per service, which is very competitive for the class.

Servicing intervals are at every 12 months or 10,000km, whichever occurs first, but could be annoying if you travel a lot.

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.
