Mercedes-Benz GLA-Class vs Audi Q3

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 hate how this car has challenged my long-held belief that coupe SUVs are silly. Even more so than other notable examples I’ve driven, like Mercedes’ GLC 53.

It’s so sleek and stylish, drives beautifully, and is so packed with immersive technology that I had to triple check the price. The Sportback takes everything good about the Q3 and makes it even better looking with barely a penalty to practicality. Bravo.

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.

This is the best-looking coupe SUV I’ve seen. Do you agree?

You could argue the Porsche Macan is up there alongside it, and I’d agree, but it’s also at least $20K more expensive.

Volvo’s XC40 maybe comes close in terms of exterior appeal, but it isn’t a coupe.

You can see elements of Lamborghini Urus (an Audi subsidiary) in the air dams and roofline, and there’s a complexity to it which hints at the tech within.

In fact, I’d say this Audi is so swish I kind of understand now. This is what coupe SUVs are meant to be about. Redefining the ‘SUV look’, inside and out.

Why pretend SUVs are about off-roading anymore? They’re really about comfort and convenience in the confines of a city.

Of course, the ‘inside’ bit comes naturally to the Q3, which has a swish, simplistic, but wonderfully advanced cockpit.

The design is upright, but not imposing, spacious, but not barren. The slight driver focus of the vents, touchscreen, and controls is noted and appreciated.

Both screens are ultra-high resolution, sharp and crisp to look at, and it adds so much to the lustre of everything you use, fitting seamlessly with the sharp and detailed lines in the dash. The fully adjustable LED interior ambient lighting is wholly unnecessary but does make it a nice place to be at night, and changing the colours entertained my family members no end.

Virtual Cockpit is still unrivalled for its aesthetics and ease of use, too. The wheel is even notable for its neat proportions and comfortable shape.

What don’t I like? The tall plasticky shift-knob still looks like it belongs in a base-model VW Polo, and some padding around the centre tunnel for the knees would be appreciated.

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.

We like the practicality in the regular Q3, but is the Sportback too compromised? Let’s take a look

The front two passengers are treated to a spacious and airy cabin, with loads of glass and space for your elbows. You can adjust the height of the centre box to suit your driving position, and there are no complaints when it comes to leg- or headroom.

Tech spills out of the dash and into your hands. USB-A, USB-C and wireless connectivity are available to you. In fact, wireless Apple CarPlay is as revolutionary as keyless entry.

You set it up once and that’s it. Just turn the car on, leave the phone in your pocket and the media system does the rest. The cost is a slight input lag, but the payoff of just being able to throw your phone in the charging bay or simply leave it in your pocket and forget about it is well worth it.

Storage areas are abundant for front passengers with big cupholders with a large centre slot for a phone or wallet perhaps, the large wireless charging bay and a small but useful centre console box.

There are also small bottle holders in the doors and a decently-sized glove box.

A small annoyance comes from the high-resolution screen. Some items become too fine to accurately jab at without taking your eyes off the road, particularly in Apple CarPlay mode. Thankfully all essentials, like the climate and volume controls have physical dials.

Visibility out the front and sides for the driver is fantastic, although there’s no denying the smaller rear aperture in the Sportback’s design makes seeing out the rear a bit more difficult.

Rear passengers are treated to a customizable area. The rear seats are on rails, and I found my legroom to be more than adequate in the standard, furthest-back position. I could have moved the seat about 20 per cent further forward without running into issues.

Height is a different story. I’m 182cm (6.0ft) tall and fit okay with maybe a couple of centimetres space above my head. My slightly taller brother (around 185cm) had his head pretty much up against the roof. The standard Q3 had no such issues, but it’s worth considering if you plan to regularly transport taller family or friends.

The back of the rear seats are clad in plastic which looks nasty but will be good for those with kids, and rear passengers can make use of two USB-C ports, a 12V outlet and dual adjustable air vents on the back of the centre stack.

Boot space comes in at 530 litres (VDA) with all seats in their default positions which proved more than enough for our largest CarsGuide suitcase, some duffel bags, and camera equipment.

It can be adjusted up to 1400L with all the seats stowed. Apparently, this is no less than the regular Q3, which would make sense as the space is meant to be measured to the parcel shelf, before the more aggressive roofline starts to cut its shape.

Our test car is the 35 TFSI (which means it has the least powerful Q3 engine) in Launch Edition trim. In Sportback form, I think it looks a million bucks, but was surprised and taken aback by how affordable it is by premium car standards.

Wearing an MSRP of $56,450, this Q3 isn’t bad value, especially when lined up against similar spec competitors like Volvo’s XC40 (Design - $56,990). BMW’s ageing X1 sDrive 20i is significantly cheaper up-front ($48,500) but will require a fair few option packs to be on-par with this Audi. And even then there are some tech items which the Q3 will have over it.

We don’t know how much Mercedes-Benz’ GLB will cost yet, although it’s a different small SUV beast with a chunky backside and seven seats.

Standard spec includes 19-inch alloy wheels, an impressive 10.1-inch multimedia touchscreen, Android Auto and digital radio with wireless Apple CarPlay (!), wireless charging, 10-speaker audio system, Wi-Fi hotspot, built-in nav (with online traffic and other services), 10.25-inch ‘virtual cockpit’ digital dash, dual-zone climate control, leather seating, heated and powered front seats with heated steering wheel, auto dimming rear view mirror, keyless entry with push-start, LED headlights, as well as surround parking sensors and cameras.

The options list is surpisingly short and affordable at this end of the market, consisting of a Bang & Olufsen surround speaker system ($900), full paint finish bumpers ($450), park assist ($300), ‘Matrix’ LED headlights ($1300 – why? The standard ones are fine), panoramic opening sunroof ($2080), and electronic dampers ($1700). You’ll note all are luxuries and won’t make or break a sale for anyone.

It’s also worth noting the Q3’s relatively high standard spec complements its almost segment-bending dimensions, which will have some considering whether they really need something slightly larger again like an X3, GLC, or Audi’s own Q5.

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.

Powering 35 TFSI variants is a 1.4-litre turbocharged four-cylinder petrol engine, producing 110kW/250Nm. It’s mated to a six-speed dual-clutch automatic transmission and powers the front wheels only.

An all-wheel drive version with a 2.0-litre engine is available further up the range.

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 35 TFSI has a claimed/combined fuel consumption figure of 7.3L/100km, against which I scored 8.4L/100km on my weekly test.

That number's very good for something this size, probably helped along by the 35 TFSI's relatively light 1545kg kerb weight.

Oddly, and unlike most VW Group vehicles with similar drivetrains, the Q3 35 TFSI does not have a stop/start system.

The 35 TFSI requires 95 RON premium unleaded petrol and has a 60-litre fuel 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 Q3 offers a slick, modern, and comfortable drive, but not one without its flaws.

The ride is superb. A great balance of sportiness and damping, the Q3 keeps it stable in the corners, but comfortable over bumps. This was helped along by comfort-spec Hankook tyres on our car, and the 19-inch wheels proved to be a sensible size.

The only thing which seemed to transmit unpleasantness into the cabin was the dampers going out of frequency on rutted roads. I couldn’t help but note the similarity of the Q3’s ride characteristics to those of the new VW T-Roc, a size under.

Inside is quiet and refined, and all of the Q3’s features are ergonomic and easy to use to the point where you take it for granted. But with the Sportback’s cropped rear window, seeing out the rear isn’t as easy as it is in the regular Q3.

The engine has sufficient power when the boost, and subsequently peak torque, sets in, the trouble is this can all happen very suddenly.

There’s a delay when stomping on the go-pedal, which is replaced a full second thereafter with a surge of torque. It takes a bit of getting used to working in a moment of restraint while you wait for power to arrive.

Get impatient, and the Q3 will simply spin its wheels off the line. It’s not a problem isolated to this car, but one I also found in other VW Group vehicles with similar drivetrains. The Tiguan comes to mind.

A neat trick is setting the Q3 into the sportier ‘Dynamic’ mode and then switching the transmission from ‘S’ to the regular Drive. This gives you the best of a more responsive powertrain without having the transmission hang around in gears for too long.

The six-speed can still be caught out fairly easily as it tries to be ‘smart’ about its changes to a fault. I wonder how well its computer would go about learning your driving patterns long-term.

All up, the Q3 offers a nice balance of SUV comfort and hatch-like sportiness thanks to its light frame. The turbo engine has its small issues, but there are no red flags here for urban commuters.

The Q3 has a maximum five-star ANCAP safety rating (awarded in 2018) which covers all variants.

The advanced safety systems standard on the Launch Edition include auto emergency braking (up to 250km/h, detects pedestrians and cyclists up to 85km/h), lane keep assist with lane departure warning, blind spot monitoring, rear cross traffic alert, adaptive cruise control (with stop and go function), and driver attention alert.

Several of these items, like the adaptive cruise are not standard on the base car and require an optional ‘Comfort Package’. Tick that box if the Launch Edition is sold out by the time you’re reading this.

Expected safety inclusions are six airbags, electronic stability and brake controls, and hill assist systems..

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.

Audi’s standard warranty offer of three years and unlimited kilometres is annoyingly short, but not unexpected from a premium brand.

The pressure is on though, with Mercedes-Benz and newcomer, Genesis, now offering five years of warranty coverage, as well as Japanese stalwart Lexus offering four years.

Audi was even considering making a promotional five-year unlimited kilometre warranty permanent at the time of writing, so hopefully that has come to pass by the time you’re reading this review. Time will tell.

Where Audi makes ground back though is its very competitive service pricing. We’d strongly recommend bundling in an Audi ‘Genuine Care’ service plan at the time of purchase which will make your servicing much cheaper.

Three years of servicing for the Q3 under this scheme is $1610, while five years is $2630 it’s worth it. All Q3s require servicing once every 12 months or 15,000km.
