Mercedes-Benz GLA-Class vs Mazda CX-30

What's the difference?

With Mercedes-Benz’s vast number of SUVs, there is room for an urban luxury crossover niche, and the GLA delivers in spades.

Indeed, in 250 4Matic guise, it is that rare thing – a high-riding hatch with dynamics to shame most dedicated pocket-rockets. It really is a hoot if you find the right road, regardless of weather conditions. The Benz has towering talent.

However, even without desirable options like adaptive dampers and a full suite of driver-assist safety technology, the GLA is expensive, does not quite carry off the price tag from an interior quality point of view, and struggles to maintain the degree of comfort and refinement expected from a Mercedes – with or without the $3K necessary to score adaptive dampers.

Still, especially because of the way the GLA looks, goes, stops and steers, if you can afford it, you’ll be rewarded. There’s never been a more rounded GLA.

I’m glad we checked in on our old friend, the Mazda CX-30. Despite being a car with two wheels planted in the future, and two firmly planted in the past, it manages to hold the line against many of its newer rivals, both on the cheaper and higher-tech end of the spectrum.

What you see really is what you get with this Mazda; it’s lovely to drive, looks fantastic, and punches above its weight when it comes to cabin ambiance. While what’s under the bonnet might no longer be in vogue, driving this car again has only reinforced its standing as small SUV royalty.

Looking like a mini-me GLC, today's GLA trades some of its predecessor’s edgier design elements like the slammed roof and exaggerated broad-shouldered stance for a more amorphous if elegant appearance. Even with the cliché plastic cladding around the squared-off wheel arches, it’s still a looker.

The net result is arguably the most attractive of all the MFA2 A-Class offshoots. It sits well within the Mercedes hierarchy of SUVs, bringing a swoopy coupe-like silhouette compared to the ultra-upright GLB.

Along with being 30mm wider, it’s also visibly taller than before, with a handy 213mm of ground clearance compared to just 157mm last time around. And the wheelbase has been stretched to the benefit of rear-passenger room – a bugbear of the old GLA. That's progress.

While the Haval Jolions of the world look ready to hit up the McDonald’s drive thru with their youthful flair, and cars like the Toyota Corolla Cross want to save money and dine at home with their conservative appearance, the Mazda CX-30 looks dressed to impress, as though it should be seen at the valet stand of your nearest Michelin-star restaurant.

A few years of age or not, the design of this car is still spectacular at this price, placing it right at the forefront of looks for the mainstream small SUV segment.

The delicate panel work, signature big grille, and large wheels at this Astina grade match nicely with the minimalist light fittings which themselves come complete with a soft-fade effect for the indicators.

It’s attention to detail like this which makes the CX-30 look like it belongs in a price-bracket above, and demands rivals pay attention.

The interior meets expectations, too, which is no small feat given some cars in this space prove it’s one thing to look great, and quite another to match it with a truly premium feel.

Mazda has done a fantastic job in the cabin which feels the part with an abundance of soft-touch materials, a dark, modern colour scheme, and an overall vibe which is ageing well even compared to more recently launched rivals.

I would go so far as to say, at the Astina grade the CX-30 feels more like it should be competing with Lexus, certainly punching above the mark, even at its mid-$40K price-point.

Compared to before, the 2021 GLA is some 122mm taller, so ushers in a higher hip point for loftier seating – reducing that jumped-up hatch feel. Headroom improves obviously, as does rear legroom, a corollary of a 30mm wheelbase stretch (to 2729mm).

Wide apertures also make entry into and out of the German-built GLA child's play, though the solid heft of their doors is serious business at this end of the segment, very satisfyingly Teutonic and totally on-brand. This is something you won’t enjoy in a Subaru XV.

Then you s-c-r-a-p-e the underside of the front doors on the pavement literally every time you swing it to get out, and wonder whether Mercedes engineers have ever been to Australia. This fail drove us spare. Heaven help the GLAs in towns and cities with bluestone sidewalks. Maybe all that extra AMG packaging is the culprit.

Still, most of the other basics are spot-on and can’t really be faulted; cosy yet spacious for four adults – especially up front, ample vision, an excellent driving position aided by heaps of seat and steering wheel adjustability, cosseting front sports buckets that you just sink into, torrents of ventilation from those delectable turbine vents and stacks of storage. Collectively they make the GLA a welcoming, opulent place to travel in. Only the hapless fifth occupant squished between the outboard rear-seat passengers might think otherwise. But nobody buys this Benz for carting people around. That's the GLB's job.

Several years ago, Daimler poached a senior Audi designer and since then Mercedes’ dashboards have morphed into a multi-coloured multimedia diorama of touchscreen technology that threatens to completely take over the universe. Choose the right combination of colours and lighting and it's like your very own White Night on wheels. Starting with 2018’s A-Class, the striking, spangly MBUX system that underpins all this has come to be widely admired and imitated. For aesthetics anyway, with its vivid hues, panoramic displays and simple, tiled applications, it’s been a real trip.

Anyway, back to reality. From a tactility and functionality point of view, there’s still work to be done.

Access to the multimedia (including our GLA's banging optional audio system) and car settings areas is possible via a mildly fiddly finger-pad arrangement down forward in the centre console, or smaller yet much more annoying thumb sensor tabs on the wheel spokes. These are not easy to modulate on the move. Additionally, their menus can be confusing to navigate through and sometimes counterintuitive in operation. Mercedes obviously realises this as a quick-guide pamphlet is provided on old-fashioned cardboard paper. How quaint.

Eventually all areas can be mastered over time, but the functionality is complicated and may overwhelm the not-so-tech savvy. Additionally, the ‘Hey, Mercedes!’ voice control is impressive for getting MBUX to perform basic multimedia and vehicle settings-related changes, but it too-often erratic, unreliable and ultimately frustrating for more complicated commands. Perhaps elocution lessons on behalf of the operator may help.

But not as much as the profound disappointment we endure from the cheapness of some of the materials, the wincing cellophane-like sounds when pressing on some of the surfaces such as the door cards, or that emanate after a particularly bumpy section of bad roads. Sheeny reflections and hard textures in a car optioned with extras that total up to nearly $82,500 just don’t cut it.  

At least in this latest-gen GLA, the rear seat area seems much improved over the previous models, with more space, comfy and supportive seating (remember ours featured the $607 sliding function that ought to be standard) and a reclining backrest. All amenities are present, with deep pockets, fresh air from twin vent outlets, reading lights and thoughtfully placed armrests – but, again, the latter’s extendable cupholders feel brittle and cheap.

Further back, the 435-litre cargo area is sufficiently sized and practical for smaller family use (at last), aided by a 40/20/40 backrest fold and that slide-able cushion to extend capacity further. There is no spare wheel, but a tyre inflation kit is fitted in lieu.

Overall, then, better than before, with that fundamental rock-solid heft, luxurious aura and alluring premium-car aroma. The dazzling MBUX screen-related visuals, too, are endlessly entertaining to explore when the vehicle is not moving, but the GLA’s cabin is still not quite up to Mercedes’ reputation for exacting over-engineered excellence.

Or even to the standards of some mainstream alternatives.

It looks good and feels good, but is it practical? While the CX-30 is larger than its smaller CX-3 sibling, it still leaves space to be desired, especially compared to some other segment-bending small SUVs it competes with.

The front seat is not where the bad news starts though. It feels spacious enough inside for a couple, with large seats, plenty of space separating the front two occupants, and plenty of comfort on offer with padded armrests on both sides.

There are big bottle holders in the doors and in a flip-open bay in the console (wouldn’t want to interrupt this design… ), and there’s additional storage once you slide and flip open the armrest.

To keep things tidy, your USB and 12V power connections are also located in the console bay. No need for messy cables, and there’s a little divider, too.

On the downside here, there’s a chunk of dead space under the climate unit, which looks like it could be filled with a shelf or, better yet, wireless charger. As it is, it’s just a plastic panel with a small bay underneath which barely fits a phone.

Adjustability is great for the driver, with a reach- and tilt-adjustable steering wheel, and high belt-line offering a sporty hatch-like feel, which I instantly felt comfortable with.

The rear seat isn’t as impressive. While the fancy seat trim and soft-touch points mostly continue, some of the padding in the doors has been replaced with hard plastic, and there’s a raise in the floor to facilitate all-wheel drive on some variants which eats into the centre occupant’s foot space.

Behind my own seating position, my knees have a tiny amount of room, and so does my head, at 182cm tall. Technically, I fit, but it’s close, and feels it.

Rear occupants get a padded drop-down armrest with two bottle holders, an extra two surprisingly large ones in the doors, but no power outlets. There are two adjustable air vents on the back of the centre console.

The coupe-like design also has a cost when it comes to boot space. There’s 317-litres (VDA) of space available, although we could only fit the CarsGuide luggage set when the parcel shelf was removed.

The space is suitable for a couple on a weekend adventure, but a bit tight if you have more requirements, like a pram-age child, for example.

There is an under-floor space which houses a space-saver spare wheel and part of the Bose sound system.

When Mazda started what seemed like a push upmarket at the time, the CX-30 was an expensive small SUV. The intention with this car’s look and feel seemed to match the pricing, though, so we all thought Mazda was trying to establish a new semi-premium positioning.

As fate would have it, though, through a pandemic and various fluctuations when it comes to supply and raw material costs, every other manufacturer in this mainstream small SUV space has pushed up the price-scale, too, now making even the more expensive versions of the CX-30 look not so bad value after all.

The specific version we have for this test is the top-trim Astina, using the larger 2.5-litre engine in front-wheel drive form.

The CX-30 range is expansive and confusing, because you can also have an Astina with the smaller 2.0-litre engine, or in all-wheel drive, or even with Mazda’s odd new ‘X20’ engine option which is effectively a supercharged compression-ignition science experiment.

This front-drive 2.5-litre version is probably the pick of the Astina bunch, though, offering the larger engine without the weight or unnecessary cost of all-wheel drive.

Wearing a before on-roads price-tag of $43,310, it now goes into battle with the surprisingly expensive Toyota Corolla Cross (Atmos FWD - $43,550), Honda HR-V (e:HEV L - $47,000), Volkswagen T-Roc (R-Line AWD - $45,200), and the almost as expensive top-spec Kia Seltos (GT-Line FWD - $41,500).

Of course, if these prices, which will approach $50K once you factor in on-road costs, are making you wince, there’s always the more affordable Haval Jolion (from $36,990 for an equivalent high-spec S) or the MG ZST (from $34,990 for an equivalent Essence) from China.

If you’re thinking neither will hold a candle to the Mazda’s dynamics or quality, you’d be right. Read on to learn why.

Before we go on, though, at this Astina grade equipment includes 18-inch alloy wheels, an 8.8-inch multimedia panel with wired Apple CarPlay and Android Auto, LED headlights, a sunroof, heated front seats with power adjust for the driver, a 7.0-inch digital instrument element, surprisingly nice leather interior trim for the seats and wheel, dual-zone climate, a head-up display, and a 360-degree parking camera.

Interesting omissions at this price include a wireless charger, wireless phone mirroring, USB-C connectivity, and while there’s a great safety suite included, there’s also no true hybrid option in the CX-30 range.

Mounted transversely, Mercedes’ M260 1991cc 2.0-litre four-cylinder petrol engine features a twin-cam, 16-valve design, a twin-scroll turbocharger and variable-valve timing, to help deliver 165kW of power at 5500rpm and 350Nm of torque at a low 1800rpm. With an impressive 97.2kW per tonne, it can hit 100km/h in 6.7 seconds, on the way to a 240km/h top speed.

All four wheels are driven by an eight-speed dual-clutch transmission (DCT), though most of the torque at lower speeds or during reduced throttle loads is delivered to the front wheels until extra traction is required out back. The gearbox is one of the very best of its type we’ve experienced – seamless, strong and largely lag-free.

This is where the Mazda is really showing its age. G25 variants are powered by a 2.5-litre four-cylinder engine, which isn’t turbocharged, nor is it assisted at the wheels by electric motors in a hybrid arrangement.

It’s punchy enough to keep the pace with most of its turbo rivals, putting out 139kW/252Nm, and some will love the fact it’s paired with a traditional torque converter automatic instead of a rubbery continuously variable or glitchy dual-clutch set-up, but it’s certainly not for the eco-conscious.

Not only is it a relatively large displacement engine, but aside from a start-stop system there’s little to mitigate your emissions. In fact, this unit only complies with Euro 5 emissions regulations, well behind the pace today.

Weighing in at 1668kg (kerb), and with a bluff nose and high ground clearance also not helping, we didn’t expect great fuel economy, particularly given how hard and fast the GLA 250’s performance bandwidth is. It’s tempting to just blast your way from point A to point B.

However, at the pump we averaged 9.8 litres per 100km, which isn’t too bad at all considering the available muscle. The official figure is 7.5L/100km, for a carbon dioxide emissions rating of 170 grams per kilometre. With a 51-litre fuel tank, the theoretical range is around 680km.

Note that the GLA 250 requires 95 RON premium unleaded petrol as a minimum.

Some bad news, of course, comes at the fuel pump. The official claim for this relatively large engine is a bit bold, at 6.8L/100km on the ADR combined cycle, but if you’re using it for mainly urban duties as we did for this review I wouldn’t be surprised to see figures more in the region between 8.0 and 9.0L/100km.

As it stands, our car produced an average of 7.8L/100km, which is better than expected, but still painful in the era of hybrids and fuel-sipping turbos, especially when fuel is close to $2.00 a litre in most capital cities.

Mercifully, the lack of complexity from this engine does mean you can put bog-standard 91 RON unleaded in the tank.

A soaring 2.0-litre turbo engine application, this is a slick, stirring and robust performer that can also do efficiency as effortlessly as launch the GLA 250 4Matic towards the horizon. Let’s not mince our words. This is a fast and fiery mover.

Three drive modes – Eco, Comfort and Sport – provide a wide spectrum of acceleration and throttle responses, and all deliver precisely what you’d expect. Eco’s fine for pottering around town smoothly and serenely; Sport morphs into a searing and seamless speed demon; and the default Comfort sits somewhere in the middle as the best of both worlds. There really is no faulting Mercedes’ M260 masterpiece.

The DCT also happens to be one of the better dual clutch autos, avoiding the lag and clunkiness pitfalls usually associated with this sort of gearbox. It’s even comparatively smooth off the line on hills. Ours came with the optional handy set of manual-mode paddle shifters, adding a welcome level of interactivity autos tend to overlook. Too bad Mercedes persists with that fiddly column lever that is forever prone to knocking the car out of drive. Even after 15 years, it's still so annoying.

What all this means for the urban driver is strong acceleration for flitting in and out of traffic gaps, as well as incredibly instantaneous point-to-point responses for commanding manoeuvrability, thanks to ultra-eager steering and assisted by outstanding brakes.

With struts up front and a multi-link rear end as standard, the GLA 250’s chassis, too, is a transformative for what is essentially a high-riding hatchback – but only if your pockets are deep enough.

Fitted with that near-$3K AMG Exclusive Package that includes adaptive dampers, our Benz displayed a definite hot-hatch attitude that really would make it the darling of Golf GTI owners who’ve outgrown their rides but not their girl/boyracer desires. Superb handling and hunkered-down roadholding really do make this the driver’s premium compact crossover. You can pretty much point and shoot this Merc as you might a Golf R, and likewise in most weather conditions thanks to all that reassuring tenacious grip.

Plus, if you’re put off by the hard ride in Sport, the Individual mode allows the driver to engage the soft damper mode while the engine and steering retain the hardcore settings. It’s a win-win situation – as long as you can stretch to that AMG Exclusive pack. We strongly recommend it, given the balance between ultimate high-speed control and comfort.

However, while this is all good news for rural and country folk seeking hot crossover fun, back around town, poor urban road conditions can reveal a flaw in the chassis’ ability to properly smother bumps and ruts. It’s the small frequency stuff that seems to transmit through, never really settling down.

The result is a jittery ride, that may somewhat undermine the GLA’s upmarket sheen. There’s also a fair degree of road noise coming through. Perhaps sticking with the 19-inch alloys instead of those lovely 20-inch rims is the solution here.

The CX-30 is awesome to drive. In a sea of lacklustre small SUVs, it’s instantly easy to connect with this Mazda. Yes, the engine and transmission here aren’t the most recent additions to the landscape, but they are predictable, smooth, and easy to deal with.

In fact, one thing Mazda is particularly good at is making its entire range feel homogenous in terms of the drive experience, maintaining the great dynamics which the brand has become synonymous with.

The touchpoints continue to be fantastic on the move. The steering feels light and easy to turn at low speeds, but becomes purposeful and full of feel at higher speeds.

The direct feedback on offer from the rack and the firm springs up front give a great handle on what the front wheels are doing.

The overall feel is firm and reactive, ready for action, and while not everyone will love the hard edge to the suspension, it helps the car feel springy and agile in the corners.

You can feel the Mazda 3 DNA on full display when you’re driving this car in haste, and it’s a kind of dynamism which most rivals can’t match, even if the Mazda’s drivetrain is feeling a little low-tech.

You certainly don’t need to worry about the six-speed transmission, which is a smooth-shifting unit.

There’s no glitchy behaviour on hills or from a stop like you might get in a dual-clutch, or rubbery surging under acceleration often delivered by a CVT, just the feeling of the car riding each gear out, and shifting between clearly defined ratios.

Drivers of older vehicles especially will appreciate its instantly familiar feel.

Ergonomically, it’s pretty straightforward, with the one major downside being the dial set-up. We like physical controls rather than touch controls, but Mazda has taken this to the extreme by not making the main multimedia screen a touch unit.

Instead, you’re forced to negotiate with phone mirroring software using a rotary dial, which is at best clumsy, and at worst distracting.

It’s also a tad difficult to see over this car’s high beltline, making it hard to tell where the corners are, front and rear, and a common Mazda problem is the wing mirrors which seem to have a zoom factor on them. Why? It limits your view into the lanes next to you.

Thankfully the active safety suite spends most of its time in the background and unlike some more recent offerings in the small SUV space, not interfering with the excellent drive experience.

The lane keep software is light handed, and the driver monitoring tech is more basic, which is honestly all you should need.

Overall then, the CX-30 is predictable, familiar, and has a fantastic quality to its handling which fits the Mazda brand promise.

Aside from a few blemishes then, it’s one of the best cars to drive in the segment, just don’t expect it to feel as cutting-edge as it could.

I love the lack of invasive safety tech in the CX-30, but that’s not to say this car lacks any of the required gear.

Active equipment includes freeway-speed auto emergency braking, lane keep assist with lane departure warning, blind-spot monitoring with rear- and front-cross traffic alert, adaptive cruise control, adaptive high-beams, driver attention alert, and traffic sign recognition.

You also score a very nice 360-degree parking camera and sensors, as well as a suite of seven airbags.

The CX-30 scored particularly highly across all of ANCAP’s testing criteria, with a particularly impressive 99 per cent in adult occupant protection. It achieved this rating in 2020.

Unlike many luxury brands that persist with a sub-par three-year warranty, Mercedes-Benz offers a five-year/unlimited kilometre warranty.

Intervals are every year or 25,000km, with a capped price service plan starting at $550 for the first year, $750 for the second year and $1250 for the third year, totalling $2550. Alternatively, buyers can also choose a Service Plan, starting at $2050 for the first three years (saving $500 from the normal capped-price service plan), $2950 for four years and $3500 for five years.

As with all Mazdas, the ownership proposition is pretty straightforward. There’s five years of warranty, five years of roadside assist, and five years of capped price servicing.

Service costs are pretty tame, too, with our front-drive G25 Astina working out to an average of $360 per year for the first five years.

You’ll need to visit a workshop once every 10,000km or 12 months, whichever comes first.
