Mazda 3 vs MG ZS

What's the difference?

Given how effortlessly it traverses the mainstream and premium small car classes, the Mazda 3 might be the best value small car on the planet.

With racy styling, sports car handling, classy interior presentation and impressive, intelligent efficiency, there’s plenty to sink your teeth into here.

Poor rear vision, a dark back-seat area and smallish boot aside, it doesn’t have any glaring faults.

In a world overrun with SUVs, props to Mazda for evolving the small car so brilliantly to mask a half-decade of existence. Continuous improvements have made the 2024 G25 Evolve SP Vision an essential small car shortlist proposition, regardless of price.

The MG ZS Essence with the 1.5-litre petrol engine has many strengths - price and value for money, practicality and space, good looks… and the only area where it really struggles to match its rivals is its underpowered engine. 

The good news is the Essence also comes with a turbo engine and while this isn’t a race car by any means, turbocharging is a way to add the oomph needed in a car this size. 

Stepping up to the MG ZS Essence Turbo costs an extra $2000, but if you can make the budget stretch you’ll have the complete package of value, looks, practicality, safety and much better performance for more enjoyable driving.

How is it that the current Mazda 3 is already five years old? This hatchback is still stunning, the sort of car you look back at when walking away.

The shape is sleek and almost coupe-like, with a shark-like nose, cab-backward-style long bonnet, upswept shoulder line and a fastback silhouette.

More importantly, it’s the way the light dances across the sculptured sides that draw the eyes in. Bereft of clutter, it makes you wish all mainstream manufacturers had the courage to be so daring.

We’ve said it before – the 'BP'-generation Mazda 3 (Axela in Japan) is the brand’s boldest C-segment hatch since the 1993 'BA' 323 (Astina/Lantis/323F).

But there’s a price to pay for such timeless beauty…

The ZS's good looks is another strength.

The new-gen ZS arrived in Australia late in 2024 and this petrol version landed in February 2025. The styling looks more expensive and premium than its price tag would suggest. The sleek nose, the refined tail-lights, a pleasing profile all make for a good looking small SUV.

There are many interesting elements in the design - the grille and its aggressively looking flanking 'air intakes', the crease through the door panels, the little fin that meets the tail-light.

Squint and it looks like a mini Ford Territory. Sort of…

The cabin of the ZS Essence is equally refined with a modern design and soft touchpoints throughout. It’s a minimalist and spacious place free from button clutter.

The ZS is 4430mm long, 1818mm wide and 1635mm high. Ground clearance is 161mm, in case you’ve been lying in bed wondering.

There is a price to pay for all this quasi-coupe styling flair, and that’s a comparatively snug-feeling interior, though you’d never call it cramped.

Actually, the Mazda 3 is no less spacious than most of its competition in all but one area, with enough room even for 200cm drivers, along with sufficient shoulder width and ceiling height to match.

If you’re really tall, maybe that missing sunroof isn’t such a bad thing, after all.

Sat so low-down on cushy, enveloping front seats that offer plenty of comfort and support, this is the anti-SUV. Maybe Mazda should have called this the MX-3.

Sporty and spot-on, the driving position is a laid-back affair, with an emphasis on better ergonomics, as emphasised by the thoughtful placement of switchgear that’s all within easy reach, ahead of a beautifully flowing and layered dash. Proudly Japanese in flavour, it brings to mind functional minimalism.

Drilling into some of the 3’s finer interior details, the analogue-look digital instrumentation is super-legible, ultra-classy and gorgeously lit at night. As previously mentioned, the dials and surrounding air vents are reminiscent of the later Porsche 944 and 968.

It’s not just all for the sake of aesthetics, either.

Yes, it’s lovely, but the thinned-rim three-spoke steering wheel feels great to grip, with nifty little paddle shifters that are a delight to prod.

Same goes for the physical volume knob and climate-control buttons, sidestepping the need to get distracted and frustrated by virtual sub-menus.

And having a conventional gear lever with old-school Tiptronic-style shifts suits the 3’s athletic vibe.

Plus, forward vision is A-OK, ventilation is faultless, storage is better than you might expect, and the fit and finish is as good if not better than any of this 3’s German premium opponents.

Out back, the split-fold rear backrest is set at a comfortable angle, the cushion is well padded, and you’re provided with USB ports, air vents, and an armrest with two cupholders. More thoughtfulness.

But while knee room is fair, rear headroom isn’t great if you’re tall or wear a beehive, as the falling ceiling line reveals.

Vision out is limited by that rising window line and fat pillars. Getting in and out of the back requires some contortionist moves. And the small windows mean it can be gloomier in the back than a Smiths album.

Finally, at just 295 litres, the 3’s cargo capacity is disappointing. Sure, it eclipses the Corolla hatch’s 217L cubby, but other rivals are far larger back there.

At least the floor is wide and flat and there are 60/40-split backrests for cabin access for longer items.

Note that a space-saver spare wheel lurks underneath. Mazda argues there’s always the closely-related CX-30 if you need (slightly) more space (317L).

Meanwhile, at the other end of the 3…

Practicality is a big strength, too, with a proximity key that’ll unlock the car when you touch the door handle, and a cabin with good legroom and headroom even for me at 189cm tall.

There's also a wonderfully simple charging pad for your phone - it's a large area on the centre console which works well in terms of connection but also in terms of wasy access. Many rivals will hide phone chargers away is small crevices that make them hard to extract or even pop in.

You'll find four USB ports, too plus a 12V charger, too.

Clever storage like a shelf built into the dash for loose objects, four cupholders and big door pockets are also on hand.

The boot is also a decent size for a small SUV at 443 litres which is bigger than many rivals, including the Subaru Crosstrek.

The MG ZS’s biggest strength is its affordability and the petrol variant in the Essence grade we tested is a relative bargain at $29,990, drive-away. The entry-grade Excite is even cheaper at $26,990, drive-away.

The Essence offers more standard equipment though and is worth the extra three thousand if you can afford it. Coming standard are LED headlights, 17-inch alloys wheels, silver roof rails, a panoramic sunroof, proximity unlocking, push button start, a 12.3-inch media screen, sat nav, digital radio, six-speaker audio, heated front seats and a leather steering wheel.

That’s good value, and we can testify the LED headlights are excellent for a night-time country road, the proximity unlocking is hard to live without and the heated seats do get very warm.

But the stereo’s sound is 'meh' and the shade on the panoramic roof could be thicker to block out the intense Aussie sun.

Also the seat upholstery is vinyl and while it is easy to clean and looks great, it doesn’t have the nicest feel to it. Still, the car is $29,990 and is better value than the Kia Seltos and a few other rivals.

When you think about it, shoehorning a big torquey engine in a light and agile small car is a recipe for fun. Ford did just that with the Escort RS2000 in the 1970s… and Mazda’s now an expert at it, too.

The engine in question is the G25, a 2.5-litre four-cylinder naturally aspirated twin-cam petrol engine, delivering 139kW of power at 6000rpm and 252Nm of torque at 4000rpm.

As this Evolve SP Vision hatch tips the scales at 1415kg, it makes for a healthy, and consequently very lively, power-to-weight ratio of over 98kW/tonne.

That’s if you decide to use all the available revs, which the six-speed torque-converter auto makes great use of.

Driving the front wheels, it offers a 'Sport' mode to extend the revs even more, which is keeping in line with this Mazda’s sporty character.

Less so is the company’s decision to ditch the old multi-link independent rear suspension system a few years back for a more prosaic torsion beam arrangement. We’ll get to how that affects ride and handling in a moment.

Okay, we've listed a lot of strengths for the MG ZS but the engine isn’t one of them. The 1.5-litre four-cylinder petrol engine makes 81kW and 140Nm.

Really, power needs to be at least 100kW and torque closer to 200Nm in something weighing 1330kg otherwise acceleration is going to feel woeful - which it is.

Seriously, the first time I tried to overtake I looked down to see if the handbrake was still on.

Not helping performance is a CVT (Continuously Variable Transmission) which, while good for fuel economy, seems to have trouble getting power to the road effectively.

Mazda claims the G25 averages 6.6L/100km on the combined cycle… for a carbon-dioxide emissions rating of 154g/km. On a 51L tank, that gives a potential distance of over 940km!

Driven good and hard in our hands, we managed 7.5L/100km, which isn’t bad given the speed and conditions it was subjected to.

Plus, the Mazda’s happy on 91 RON 'standard' unleaded petrol.

Official fuel consumption for the combined (urban/extra-urban) cycle is 6.7L/100km, which isn’t outstanding, especially compared to the hybrid version which can get 4.7L/100km.

Our own testing after city driving and motorways saw 7.9L/100km. Not the most efficient engine in the range, so if it’s saving petrol you want then go for the hybrid, or better still, the electric version of the ZS.

Ask yourself. What do you want from a new small car?

Since the first Familia of the early 1960s, Mazda’s been at it constantly, through the 1300 and 323 eras and into the modern age of the 3.

The Hiroshima brand knows its stuff. Space, practicality, comfort, ease, reliability and affordability. But a small car has to offer more, specifically in the way it makes the owner feel.

That’s why, while the Focuses, Lancers, Astras and Pulsars are gone, the 3’s still here. And it isn’t just the lush visuals inside and out that are, well, sensory-rich.

As older Alfa Romeo owners know, there’s something special about an engine that sounds alive, and the moment you push the 3’s starter, it purrs into life. That’s the first clue.

Slot the refreshingly old-school lever into Drive, and the G25 leaps into action, and, if you need it to, will keep pulling forward strongly, engine buzzing, like it’s on a mission.

That describes the torquey urge of this big 2.5L four, paired perfectly with the sensibly-geared auto.

We miss Mazda’s magnificent manual immensely, but the 3’s instant response reflects its favourable circa-100kW/tonne power-to-weight ratio.

And, as we’ve harped on in the past, the twin-cam unit’s extra oomph beyond 4000rpm delivers muscular high-speed responses akin to a good turbo – or a great old-school Alfa. You can keep your laggy dual-clutch transmissions, Europe.

Now, sweet, smooth and speedy performance is one thing, but having the chassis tuned with precise and fluid steering for tactile handling, and confident roadholding, backed by nuanced driver-assist and traction controls, are another.

There is a consistent and unifying control to the 3’s linear and forgiving dynamics, reminiscent of past masters like the Focus (and today’s brilliant Peugeot 308) that makes it a joy to drive enthusiastically through fast corners, with the knowledge that it won’t suddenly snap-oversteer and bite an unalert driver back.

For a Mazda, the ride is quiet enough, but there is still some droning transmitted through the cabin, via the Bridgestone Turanza (215/45) tyres, on coarse-chip bitumen surfaces.

And while suspension comfort is pretty impressive for the most part, larger bumps reveal the torsion beam’s limitations, as the car can occasionally thud over them in a way that we remember the multi-link rear end wouldn’t.

Anyway, what we’re saying is that, overall, the 3 Evolve SP Vision is an immersive and interactive driving experience that is right up there with the best of them.

Brawny performance, exquisite agility and a refinement that, collectively, have eluded every small Mazda in living memory until this generation’s 2019 debut. This 3’s right on the money. Still.

The lack of oomph from the 1.5-litre naturally aspirated four-cylinder engine affects the driving experience of the ZS. This lack of accleration is hampered not just by the low outputs of the engine but also by the transmission, which is a CVT and these don't favour getting power to the road as effectively as torque convertor transmissions.

Handling is good for this class, with the ZS feeling stable under most conditions. Steering is excellent, with a nice weight and accuracy to it.

And while the ZS is no prestige car, the ride is comfortable, composed and better than many small SUVs at this price point.

Other pluses include its smaller size which makes it easy to manoeuvre in city traffic and park in tight spaces.

The final driving score however is dragged down by the engine and transmission which fail to provide the acceleration needed to easily overtake, merge or move quickly when needed at stop signs or out of car spaces on busy roads.

Safety is a strength, as well, with the MG ZS scoring the maximum five-star ANCAP assessment. Safety tech is abundant with AEB, lane keeping assistance, blind spot warning and rear cross traffic alert.

You’ll also find a clear 360-degree camera view, seat belt reminders and adaptive cruise control.

For child seats there are two ISOFIX mounts and three top tether points across the second row.

A space saver spare wheel is located under the boot floor.

Mazda offers a five-year/unlimited kilometre warranty, with five-years roadside assistance… and that’s nothing special nowadays.

Service intervals are at 12 months or every 15,000km.

A fixed-price service scheme is available, averaging out to $434 annually over the first five years. Mazda shows pricing right up to 16 years and 240,000km on its website.

Ownership costs are a strength, too. The MG ZS is covered by a 10-year/250,000km warranty.

MG’s ‘Precise Price’ service plan locks in the cost of servicing with 12-month/15,000km intervals and a cost of about $1200 over five years.
