Mercedes-Benz GLA-Class vs Audi Q5

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.

Ever since returning from the launch of the new Audi Q5 I've been looking at old ones and thinking how lumpy and dumpy they look by comparison. The new Q5 will be an adornment to our roads in styling terms, it's a tour de force of interior design and its engines might well be the last barking gasp of its kind. So it's definitely worth a look if you're in the mid-size SUV space. And you don't want an EV yet.

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

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.

Other than the closely related Porsche Macan, and maybe an Alfa Romeo Stelvio, it's hard to think of a better, smoother looking SUV than this new Audi Q5, with its revised Singleframe grille flanked by vertical air curtains, that look a bit like gills.

Audi claims the Q5 has "perfect proportions", which is bold, but it certainly looks sleek rather than bulky, with a nice silhouette and dynamic rather than Mumsy appeal.

The rear is particularly attractive with a three-dimensional light strip that ties it all neatly together. It's a more refined, sharper look than the Q5 it replaces.

Inside, of course, Audi has either taken its interior to another level of futuristic fabulousness, or put too many bloody screens in, all of which are too big, depending on who you ask. And how old they are. Kids will love it, however.

Interestingly, while every car company ever claims that its cabin has a cockpit feel, focusing on the driver, the Q5 really does. So much so that there's a raised edge in the centre console that quite noticeably cuts the driver off from the passenger. In the other front seat you do feel a bit removed, as if you're meant to leave the driver to it, which might be why you get your own screen to play with.

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.

Audi is talking up the little things with the new Q5, like the fact that there's a much larger storage space under the centre armrest now - and it's true, you can lose your car key in it - plus numerous other storage areas, and an inductive and cooled charging tray so your phone won't get cooking hot and shut off, with 15 watts of power.

In exciting news for screen addicts/children, Audi is also very excited about its uprated USB-C ports, which can charge at up to 60 watts through the two in the front, while the rear passengers also get two more, rated at 100 watts. Which sounds like a lot, Audi says it's enough to run your laptop.

The new Q5 also gets a very useful adjustable rear seat, which can be slid lengthways and tilted, providing either more passenger space and less boot room or vice versa. With the rear seat down you get 1473 litres, but thanks to the new sloping rear design you get slightly less room in the Q5 SUV, with 520 litres behind the second row. The SQ5 gets even less at just 470 litres.

Another handy feature is that the snappy luggage cover can be stowed in a special designed compartment under the boot floor. Clever.

The fact that you could get a classy SUV like the Audi Q5 for as little as $73,400 was certainly showroom bait, but that’s about to change when the new line-up arrives in the third quarter of 2025, because the entry-level Q5 35TDI will disappear from the range. 

That means the Q5 will start at the 40TDI Quattro Sport level, currently priced at $87,000 before on-road costs for the outgoing version, with its 2.0-litre diesel MHEV setup. As entry prices go, that’s quite the jump upstream, but on the plus side, while Audi hasn’t announced official pricing for new Q5 yet, the word is that there shouldn’t be much of a rise anywhere in the range (I'd read that as, there will be a price rise, but it will be small). You’ll no doubt hear the phrase “new car, more equipment, (almost the) same price” from Audi.

If you don’t want a diesel, you’ll likely be paying around $88,315 for the entry-level 2.0-litre petrol model, the 45TFSI Sport MHEV with front-wheel drive only, or $96,515 for the 45TFSI Quattro S Line.

The step up to the 55TFSI will take you north of six figures, probably by about $5k, while the range-topping Audi SQ5 will make a welcome and somewhat surprising addition to the line-up, powered by a properly noisy and exciting 3.0-litre V6 and most likely priced somewhere around $125,000, depending on spec level.

As I say, there are no confirmed prices yet so these numbers might creep higher by the time the car actually goes on sale locally, but the word is that any increases will be almost too small to notice.

The uncertainty makes it a little hard to be definitive on the value equation, but we can say that the new Q5 feels a level up inside and a lot posher, particularly with is giant multi-screen dash layout, so if the prices to stay stable you really will feel like you’re getting more car for the same money. 

In terms of spec and trim levels, we will have to wait and see until the local variants are launched.

What we know will be standard inclusions are things like the standard acoustic glazing on the windscreen, for a quieter cabin, the Dynamic Interaction Light, which runs from the doors through the dashboards and creates a very cool look at night, as do the new three-dimensional rear lights. The individually configurable, and beautifully clean and clear head-up display, with augmented reality features, should also be standard, but we shall see.

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.

Does it seem strange to anyone else that a company so focused on reducing emissions through promoting EVs is still offering diesel engines? The reason, of course, is that so many Europeans still want them, because fuel is so damn expensive there, and yet Audi Australia says it will also offer them here.

That's where the range now starts, with the TDI diesel version coming standard with all-wheel drive, or Quattro, with outputs of 150kW/400Nm. Like every car in the new Q5 range, it uses a seven-speed dual-clutch gearbox, which is excellent.

Every Q5 also uses MHEV technology to reduce emissions and increase performance, which means it gets a 48-volt electrical system to support its combustion engines. This system means you start up, in most conditions, in silent electric mode, and you can even manoeuvre and park the car using only electricity, most of the time.

The electrical system is connected to a Powertrain Generator which provides additional torque of up to 230Nm, and a mere 18kW of extra power. Every little bit helps I guess.

Basically, it's a mild hybrid, meaning you get a mild amount of help, and the full plug-in hybrid Q5s are coming soon. Later this year.

Stepping up from the diesel you can have a 2.0-litre TFSI four-cylinder petrol engine, with either front or Quattro all-wheel drive and making 150kW/340Nm.

The range-topping all-wheel-drive SQ5 gets a very enjoyable 3.0-litre six-cylinder TFSI petrol engine with 270kW and 550Nm. It feels like more kilowatts, honestly.

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.

The MHEV technology is supposed to provide some boost to fuel economy but the figures aren't super exciting. You'll be getting a claimed 5.9 litres per 100km from the 2.0 TDI diesel, or 6.5L/100km from the 2.0 TFSI petrol.

The V6 is going to cost you more at the pump with a claimed figure of 8.1 litres per 100km. You might want to wait for the PHEVs.

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.

While the new Q5 might feel classier, techier and generally more expensive and Q7/Q8-like on the inside, it's pulled off an even more impressive feat in the chassis department, which no doubt owes a lot to the entirely new PPC platform, because it feels more like a powerful Q3 to drive than the Q5 of old.

That's not a comment on interior or load space, it's just that it feels smaller and more spritely on the road. It turns in better, holds its line better and resists gentle understeer right up to the point where you wonder whether your co-driver has lost his mind or is trying to kill you both.

Seriously, the SQ5 can properly get up and boogie in Sport mode (Audi says one of the things it's proudest of with the new car is how much more noticeable the range of difference is between the relaxed, or 'Balanced' and 'Comfort', modes and the more aggressive ones) and you really have to be going beyond sensible to find the edge of grip.

The SQ5's V6 also makes the kind of noises that now sound weirdly wonderful in an Audi, when so many of the new offerings are electric. Choose to shift the gears yourself and this can be a properly involving machine, and quite impressive for an SUV.

What separates it from the kid of fun you could have in its cousin, the previous Porsche Macan with petrol power, is the steering. It's not terrible, and it is sharp, but it just lacks a bit in the feel and muscle department. Being generous you'd say it's easy to drive but you just know that if this had an R badge the steering would be so much better, and closer to Porsche and BMW.

The diesel TDI model does not make glorious noises, and the whines and groans it does make - which seem loud by Audi standards, it's usually very good at quietening its diesels down - do not encourage you to shift gears yourself or drive it in a sporty fashion. It is a workhorse variant, with plenty of torque, and for a certain kind of customer who cares not for sportiness or excitement I'm sure it's a fine option.

One thing I did not expect to be doing on an Audi Q5 launch is clambering up and over a rock strewn mountain on properly rutted and rough gravel tracks, but that was an option here so I took the 2.0 TFSI on the optional off-road adventure and I must say I was both surprised and impressed.

The Q5 is not a mountain goat, or a Land Rover, but despite feeling like I was doing the gardening in a shiny suit, I managed to traverse a track that felt too serious and intense for a soft roader, and did so with ease and in comfort. The air suspension raises the Q5 a full 45mm in Off-road mode, so ground clearance was no problem - nor did I encounter any boulders - but the way the Quattro system dealt with the dirty stuff was impressive.

Overall, I can see that this TFSI model is the sweet spot in the range in terms of value and performance, and it really is all the Q5 you could need. It never feels underpowered, unless you've just stepped out of the SQ5, and you get all the benefits of the chassis and handling upgrades.

Personally, though, I'd have the SQ5 just for the rorty V6 noises alone. It feels like something new, but also the end of something wonderful.

Obviously the new Audi Q5 has not been crash tested yet but Audi is confident of yet another five-star ANCAP rating, like the one the current car holds .

The new vehicle features more than 30 active-safety measures, which is literally too many to mention and takes advantage of its many, many radars. One gets the feeling this car could just about drive itself if the law would allow. Some inclusions are a rear parking aid with distance display, cruise control with speed limiter, lane departure warning and an attention and drowsiness assistant, all as standard.

Things like Active Front Assist, Evasion Assist, Turn Assist and Rear Turn Assist are likely to be part of options packages, but that's all still TBA.

There will also be twin ISOFIX anchor points, and top-tether points for child seats.

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.

All Audis are now covered by a five-year, unlimited-kilometre warranty, up from its recent offering of three years, which is better, but could be better still.

There's no news on what servicing arrangements will be because the new Q5 doesn't lob until Q3, but in general the brand will let you prepay your services, required annually, for the first five years, with the regular Q5 currently billed at $3140 and the SQ5 billed at $3170.
