Mazda CX-30 vs Subaru WRX

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.

Possibly one of the most perfect performance cars you can drive daily for the price. Dynamic and fun to drive, but also easy to live with thanks to the drive modes for extra comfort, the high ground clearance and the practicality that comes with four doors, lots of storage and a big boot.

The tS Spec B is the priciest WRX in the range, but compared to rivals it's also great value. A car I would buy with my own money for sure.

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. 

The WRX tS Spec B stands out from its siblings with 19-inch matte-grey alloy wheels with gold Brembo brakes and if you don’t notice any of that, then surely you won’t miss the gigantic rear wing planted on the boot lid.

The air scoop jutting out of the bonnet like a pizza oven is standard across the WRX range and it looks tough. There’s the rear diffuser which also looks beefy but also a bit plasticky, and the quad exhaust, that’s nice, and so is the note which wafts out of them at idle.

The tS Spec B’s Recaro sports seats are also in other tS grades – they do look and feel good, and offer outstanding comfort and support. 

The rest of the cabin is much the same as other WRX grades with a large portrait-style screen, physical buttons for climate control, and yes, that is a traditional, mechanical handbrake you can see in images.

This is a sporty-looking although slightly outdated cabin compared with more modern rivals.

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).

What’s so appealing about the WRX is that despite it being a performance car, it’s based on a regular 'small' sedan and with that comes all the practicality of a four-door, five-seater with a big 411-litre boot.

Space inside is excellent with plenty of room up front, while rear legroom is ample enough for me, at 189cm tall, to sit behind my driving position with plenty of headroom, too.

That all said the Recaro seats up front are on the snug side and I know they’re supposed to be, but I’m just saying they might not suit everybody – and by that I mean everybody.

Those with long legs might also find they have to adjust their driving position when letting out the clutch.

Big door pockets throughout, four cupholders, and hidey-holes for items throughout make for good cabin storage.

There are four USB ports and one 12V outlet, but no wireless phone charging to be found.

The WRX tS Spec B sits at the top of its range and lists for $61,490 plus on-road costs, making it expensive for the model compared to say the entry-grade WRX which is only $48,190 and pairs the same engine with the same gearbox.

Still, it comes with some unique features which makes this grade stand out from the other lower rungs in the WRX hierarchy.

The tS Spec B comes standard with 19-inch alloy wheels, six-piston front and two-piston rear high-performance Brembo brakes with ventilated and drilled discs, an enormous rear spoiler, STI Performance Mufflers at no extra cost, Recaro sports bucket seats in the front, a leather STI steering wheel and a 12.3-inch instrument cluster.

Also unique to the grade are drive modes which allow the suspension, engine, and steering to be customised for comfort or performance.

Standard on the ts Spec B, too, is equipment you'll find on lower grades in the WRX range, including LED headlights and daytime running lights, privacy glass, dual-zone climate control, an 11.6-inch touchscreen, a 10-speaker Harman Kardon sound system, wireless Apple CarPlay and Android Auto, proximity locking and push-button start.

Rivals to the WRX tS Spec B include the Hyundai i30 N Sedan that's $10K cheaper, and the Honda Civic Type R and Volkswagen Golf R which are both at least $10K more. The value for money in the tS Spec B is great compared to competitors, but there’s even better value to be found in the lower-grade WRXs.

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.

Who doesn’t love the sound of a boxer engine? Well, probably your neighbours if you own a WRX. And while the tS Spec B doesn’t have any more power than any of the other WRXs – with it sharing the same 2.4-litre turbo-petrol four-cylinder boxer engine as the rest of the line-up – the 202kW and 350Nm feel like the perfect amount of power and torque for this package.

It’s probably been about six months since I last drove a car with a manual gearbox, and that shows how rare they’re becoming when you’re testing a new car nearly every week.

The six-speed manual in the tS Spec B has satisfying clunky shifts and a heavy-feeling clutch pedal, but it all plays along perfectly with this engine, sending the drive to all four wheels.

If you’re looking for a version of the tS Spec B with an automatic transmission you’ll be searching forever because this grade only comes with a manual gearbox. There are WRXs with autos – well, a CVT – the entry grade, the RS and the tS.

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 WRX tS Spec B manual really likes its fuel – it’s a hungry beastie and everybody who’s about to get into the WRX life should be aware that, like most petrol performance cars, it’s not super fuel efficient.

Subaru is beautifully honest with its fuel consumption figures, which have the the WRX tS Spec B using 10.4L/100km in combined driving and 14.2L/100km in urban environment, which is so close to what we recorded - ours was 14.1/100km after mainly urban driving. You'll also have to feed it 95 RON.

The fuel tank is a healthy 63 litres in volume and that should give you a range of 606km – in theory. Do not test this theoretical range somewhere remote, okay?

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. 

This may sound strange, but a few months ago I was squished into the tiny cockpit of a 2025 Chevrolet Corvette Z06 sitting at the traffic lights wishing I was in the 2020 Subaru WRX STI beside me. And having driven so many supercars and muscle cars in the past, many costing hundreds of thousands of dollars, I still see the WRX as being such a perfect daily driver performance car.

Sure, it doesn't have Porsche 911 dynamics or the straight-line acceleration of many electric cars, but it's the way the way this boxer engine interacts so beautifully the six-speed manual gearbox, combined with sticky all-wheel drive, a wonderful balance and such direct steering that make the WRX ts Spec B feel exactly right.

The tS Spec B is very much at home in the suburbs dotted with roundabouts and obstacles like speed bumps, but they all become part of the fun of driving this car in the same way that when you let it loose and open road it performs happily and so well, too.

The suspension does feel firm, but part of the big news of this tS Spec B is that it now has a drive mode function and this allow you to adjust the suspension, the steering and the throttle response to either sporty or comfort settings. This just makes this car an even more agreeable thing to live with daily.

The WRX hasn’t been given an ANCAP rating and up until only last year manual versions weren’t equipped with safety tech such as autonomous emergency braking.

The WRX tS Spec B manual has AEB, blind-spot warning, rear cross-traffic alert, adaptive cruise control, lane departure warning and high-beam assist. 

It’s interesting but not particularly good that manual versions of the WRX don’t have parking sensors. I  don't need to tell you that parking sensors on cars in the city are so helpful for squeezing into tight spots without nudging the vehicle or railing behind you.

A space-saver spare wheel instead of a full-sized spare isn’t ideal either in Australia where dirt and gravel roads beckon the WRX.

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

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.

The WRX tS Spec B is covered by Subaru’s five-year/unlimited-kilometre warranty, which while the standard for the mainstream segment, is behind the seven-plus terms we're now seeing from a lot of Chinese and Japanese car brands.

Servicing is recommended every 15,000km/12 months and can be expensive compared to other brands, with the five years of capped price servicing coming to $2692.
