Mazda CX-30 vs Volkswagen Polo

What's the difference?

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.

The Polo GTI faces tough competition in the form of Hyundai’s recently arrived, very good, and well-equipped i20 N, as well as Ford’s sleek and super-capable Fiesta ST. But as mentioned at the start, VW occupies the hot-hatch high ground with the GTI badge, and this upgraded Polo is loaded with features, dynamically outstanding and on the leading edge in terms of safety. Time will tell if the higher price, higher spec strategy is the right one, but there’s no doubting this updated Polo GTI is a compelling package.  

Note: CarsGuide attended this event as a guest of the manufacturer, with meals provided.

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. 

Not exactly a massive change to the exterior of the Polo GTI with this mid-life refresh, but sharp-eyed car spotters will notice a new front bumper treatment including a revised lower grille, defined by a body-coloured border and flanked by LED driving lights.

The headlights have also been reshaped to mark the arrival of standard matrix LED beams, with the signature horizontal red keyline moves from the centre to the bottom edge of the upper grille. A continuous LED strip across the nose stands the car apart after dark.

Previously part of the GTI’s ‘Luxury Pack’, the ‘Faro’ design 18-inch alloys fill the wheel arches nicely, and overall the car’s compact, tightly wrapped body and finely chiselled lines are familiar.

At the back, the LED tail-light clusters have been extended laterally into the hatch door, but the car’s fundamental shape is unchanged. 

Inside the dash layout is the same, although the centre of the sports steering wheel has been massaged into a more organic shape with the airbag/horn now an oval rather than a circle.

The rest of the interior is relatively understated in typical VW fashion, the neatly sculpted sports seats trimmed with traditional ‘Clark’ tartan cloth on the cushion and backrest centres. And ‘Kings Red’ inlays in the dash, centre console and front door trims, are a reminder of the car’s heritage and sporty intent.

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).

At just under 4.1 metres long the Polo GTI is a decidedly compact hot hatch, but thanks in no small part to a relatively lengthy (2.6m) wheelbase, interior space is impressive.

The driver and front passenger have plenty of breathing room, and the rear is remarkable. At 183cm, sitting behind the driver’s seat set to my position, I enjoyed ample legroom, and more than enough headroom.

Width is another story, because while two adults will be fine in the back, there isn’t enough space for three to sit in comfort for any length of time. 

Storage options in the front include a small lidded box between the seats (which doubles as an adjustable armrest), two cupholders and various oddments spaces in the centre console, as well as the wireless charging bay in front of the gearshift. 

There are also pockets in the doors with room for (medium) bottles, a decent glove box, a shallow drawer under the passenger seat, and an overhead drop-down tray for glasses.

Map pockets on the front seat backrests, and small bins in the doors add extra practicality, but there’s no fold-down centre armrest or individual ventilation control for rear seaters. 

For connectivity and power, there are two USB-C ports in the front, plus another two in the rear, as well as a 12-volt socket in the front centre console.

Boot space is a healthy 305 litres (VDA) with the 60/40 split-folding rear seats upright, that number growing to 1079L with them folded down. 

Tie down anchors are handy for strapping loose loads, while shopping bag hooks help keep smaller bundles under control. And be aware, the spare is a space-saver.

Headline news is the Polo GTI’s before on-road costs price has gone up by close to 18 per cent, from $32,890 to $38,750. 

Why? More standard equipment; some new things and other previously optional features now included in the base price.

The aim is to bring the car into line with the specification the majority of customers are ordering, because Volkswagen believes the days of a ‘price leader’ Polo GTI are behind it. That is, pique a buyer’s interest with a keenly priced but relatively sparse base model, and they invariably add options once engaged in the process.

So, the Polo GTI has put a price gap on its two key competitors, the Ford Fiesta ST ($32,290) and Hyundai i20N ($32,990), but it’s now loaded with a whole lot of fruit for the money.

The new bits are ‘Matrix’ LED headlights, a centre airbag, and 18-inch alloy rims (up from 17s), while the elements moved from the options list to the standard equipment column are assistance features bundled under the ‘IQ.Drive’ umbrella including, blind-spot monitoring, rear cross-traffic alert, front parking sensors (joining those in the rear), ‘Park Assist’, adaptive cruise control, and auto-folding exterior mirrors.

Also included in the GTI’s base price are the ‘IQ.Light’ matrix LED headlights, ‘Dynamic Light Assist’ (auto low to main beam switch with light profile adjusted to avoid dazzling cars ahead or oncoming), ‘Premium’ LED tail-lights (with dynamic indicators), metallic paint ($600 on the Polo Life and Style), LED driving lights, dual-zone climate-control, front and rear carpet mats, ‘Digital Cockpit Pro’ (incorporating nav and phone functions), ambient interior lighting, wireless device charging, and sports front seats.

Then you can add ‘Discover’ nav in the 8.0-inch media touchscreen set-up, auto headlights, rain-sensing wipers, ‘Manoeuvre Braking’ (low-speed rear AEB), an auto-dimming rearview mirror, leather trim on the sports steering wheel, gearshift and handbrake lever, and six-speaker audio.

A ‘Sound & Tech Package’ is available for the GTI ($1500) incorporating a 9.2-inch multimedia screen, and a Beats branded premium audio system (digital eight-channel amp, 300 watts).

A Panoramic glass sunroof ($1500) is also offered, and premium metallic paint adds $300.

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 Polo GTI is powered by a version of Volkswagen’s 2.0-litre (EA888) four-cylinder turbo-petrol engine, driving the front wheels through a six-speed dual-clutch auto transmission.

The iron block/alloy head unit uses direct- and port-injection, variable valve lift on the intake side, and variable valve timing on the intake and exhaust sides to produce maximum torque of 320Nm from 1450 to 4390rpm, at which point peak power of 147kW takes over from 4390-6000rpm.

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.

VW’s official fuel economy figure for the Polo GTI on the combined (ADR 81/02 - urban, extra-urban) cycle is 6.5L/100km, the 2.0-litre turbo four emitting 150g/km of CO2 in the process. Not bad for hot-hatch with this kind of performance. 

Minimum fuel requirement is 95 RON premium unleaded and you’ll need 40 litres of it to fill the tank. Using the official consumption figure that translates to a range of 615km.

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 Polo launch drive program covered around 150km of city, suburban and freeway running from inner Sydney, through twisting B-roads to the city’s south, and sprawling semi-rural areas further west, topped off with a closed track session at the Luddenham Raceway.

Weighing in at a fraction over 1.3 tonnes, with 147kW/320Nm sent to the front wheels, the Polo GTI is capable of sprinting from 0-100km/h in 6.8 seconds, which is satisfyingly quick.

And the 2.0-litre, four-cylinder turbo-petrol engine’s dyno sheet must be a thing of beauty with maximum torque available from from 1450 to 4390rpm, and peak power picking things up at precisely the end of that plateau, remaining on tap all the way to 6000rpm.

So, mid-range punch is always there, and the six-speed ‘DSG’ dual-clutch auto delivers rapid, precise shifts, with wheel-mounted paddles dialling up the fun factor when you want to shift ratios yourself.

Combined engine and exhaust noise is agreeably rorty without tipping over the annoyance threshold, although the high-performance 215/40 Continental ContiSportContact rubber transfers a fair amount of rumble on coarser surfaces.  

The base suspension set-up is strut front/torsion beam rear, with the standard ‘Sport Select’ system built around switchable dampers, offering the choice of ‘Normal’ and ‘Sport’ modes. 

Normal is nicely composed with comfy compliance over longer undulations as well as higher frequency bumps and dips. But if the red mist descends and you’re ready for some fun the (noticeably firmer) Sport setting buttons everything down that bit more. 

As well as the damping, throttle response is faster, the DSG picks up the pace as does the steering. Even the exhaust is enhanced, although it’s via the synthetic ‘Sound Actuator.’ Boo!

Balanced and predictable in quick cornering, the Polo GTI’s electro-mechanically assisted steering is precise and beautifully weighted, with great road feel. And the car’s ‘Extended Differential Lock’ uses the traction control and braking systems to minimise wheel spin, maximise traction, and help limit understeer.

On top of all that, the carefully sculpted sports seats deliver secure location without compromising comfort, and the grippy sports wheel feels great.

Braking is by ventilated discs at the front with solid rotors at the rear, and even under the pressure of a flat-out track session (moderated with the help of some admirably patient tame racing drivers) they remained progressive and firm.

In more civilised surroundings the Polo’s size and excellent all-around vision (not to mention a clear reversing camera) make it a cinch to park. The combination of on-screen touch controls, and physical dials for the multimedia system is welcome. And the connection for Apple CarPlay and Android Auto is wired or wireless which is handy for those who prefer the surety of a wired connection or the flexibility of one less cable in their life.

The current Polo scored a maximum five-star ANCAP rating when it launched in 2018, and it must have been tempting for VW to save more than a few euros by side-stepping active and passive safety upgrades in this refresh.

But, bravo, it didn’t, the German giant re-submitting this updated version for assessment against more challenging 2022 criteria.

The GTI is loaded with a raft of crash-avoidance tech under the umbrella of ‘IQ.Drive’, including AEB (with cyclist and pedestrian detection), lane-keeping assist (with lane departure warning), ‘Multi-Collision Brake’ (automatically slows the car after a collision, reducing the chance of a secondary impact), driver fatigue detection, ‘Park Assist’ (perpendicular and parallel), front and rear parking distance sensors, rear AEB (low-speed), a reversing camera (with static and dynamic guidelines), adaptive cruise control (with speed limiter and distance warning display), and tyre pressure monitoring.

If, despite all that, a crash is unavoidable there are seven airbags on-board - driver and front passenger (front and side), front centre, and full-length side curtain.

A front centre airbag is the solution many manufacturers are using to meet ANCAP’s recently introduced, tougher criteria around head clash injuries. 

There are three top tether points across the rear seat for child seats and/or baby capsules, with ISOFIX anchors on the two outer positions.

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.

Volkswagen Australia covers the Polo GTI with a five-year/unlimited kilometre warranty, which is now the volume market standard.

The paint is warranted for three years/unlimited kilometres, “Through Corrosion” is covered for 12 years/unlimited kilometres, and 12 months roadside assistance is included.

Servicing is required every 12 months or 15,000km, with prices over the first five years ranging from a low of $455 to a high of $1498, the average per service coming out at $701, which is a pretty solid number.

Capped price servicing is available, however, over five- and three-year plans. Paying up-front for five years results in a $765 saving over pay-as-you-go.

A nice side benefit is the ability to fold servicing costs into the vehicle’s financing at the time of purchase, and the plan is transferable if you decide to sell the car before the five or three years is up.
