Mercedes-Benz GLA45 vs Audi Q2

What's the difference?

A performance SUV should be an oxymoron and is no doubt a niche product. Is it a high-riding hot hatch? Or a mega-potent small SUV?

Turns out the Mercedes-AMG GLA 45 S is a bit of both and delivers the thrills of a performance car without any of the packaging or comfort-related issues.

While it is getting a little expensive at over $100,000, its blend of space and pace is hard to beat.

The Q2 is good value and great to drive – especially the SQ2. The exterior looks new, but the cabin feels older than the larger Q3, and most other Audi models.

More standard advanced safety tech would make the Q2 even more appealing, as would a five-year, unlimited-kilometre warranty. While we’re at it, a hybrid variant would make enormous sense. 

So, a great car, but Audi could offer more to make it an even better proposition for buyers. 

The most obvious tell that the GLA 45 S is something a little special is the Panamericana front grille, an ode to the 1952 Mercedes 300 SL, which is found on all of the German brand's hot models.

But if that wasn’t enough to give it away, the reworked bumper with larger intakes, red-painted brake calipers, lower ride height, black exterior trim and 20-inch wheels should help.

Coming round to the rear, if the AMG and GLA 45 S badges aren’t enough to give away this car’s sporting intent, the quad-exhaust tips and diffuser are sure to give any tailgaters pause.

Our car also came with the optional 'Aerodynamics Package', which adds front fender flicks and a massive roof-mounted rear wing for an even racier look.

If you think the GLA 45 S looks a bit like a jacked up hot hatch, you aren’t far off. Overall, we reckon Mercedes has done a great job at translating the aggressiveness of its A 45 hatch to the larger, higher-riding GLA.

Without the aero package optioned, you might even call it a bit of a sleeper, and it’s certainly more subdued in styling compared to its Audi RS Q3 rival.

In fact, the GLA 45 S might be too subtle for such a hot SUV, at least for our tastes.

Whereas the A 45 S and CLA 45 S get bulky fenders and a hunkered-down, aggressive stance, the GLA 45 S could just blend into the sea of SUVs seen out on the streets, especially without the aerodynamics package added.

Your mileage will vary though, and for some, the subtler looks will be a positive.

Anyone who has sat in a recent small Mercedes should feel right at home in the GLA 45 S, and that’s because it shares much of its interior design with the A-Class, CLA and GLB.

As mentioned before, the 10.25-inch centre screen takes care of multimedia duties, but there are also clicky and tactile buttons underneath for climate controls.

Key to the interior design though is an all-digital instrument display, which is laid out on the high-definition 10.25-inch screen.

With two screens facing you, you might think it’s a bit of information overload, but you can tweak each display to show the information you want.

The digital instrumentation might not be as intuitive as Audi’s 'Virtual Cockpit', but the layout and design of the interior is easy to use and offers owners plenty of customisation to get it right.

This updated Q2 looks almost identical to the previous one and really the only changes are subtle styling tweaks to the front and back of the car.

The front air vents (they aren’t real air vents on the Q2, but they are on the SQ2) are now larger and pointier and the top of the grille is lower. Around the back, the bumper now has a similar design to the front, with those pointy polygons set wide apart.

It’s an angular little SUV, full of sharp-edged shapes like some kind of acoustical wall in an auditorium.

The SQ2 just looks more aggro, with its metallic-trimmed air vents and beefy quad exhaust. 

The new colour is called Apple Green and it’s not really like any colour on the road – well not since 1951, anyway when this hue was hugely popular on everything from cars to telephones. It’s also very close to Disney’s “Go Away” green – look it up and then ask yourself if you should be driving a car that’s kind of invisible to the human eye.

I digress. Other colours in the range include Brilliant Black, Turbo Blue, Glacier White, Floret Silver, Tango Red, Manhattan Grey and Navarra Blue.

Inside, the cabins are the same as before, apart from the larger, sleeker media display, and there are some new trim materials, too. The 35 TFSI has silver inlays with a diamond paint finish, while the 40TFSI has aluminium door sills.

The Q2 has beautiful quilted Nappa leather upholstery, which goes beyond just covering the seats and to the centre console, doors and armrests.

All options offer well laid out and premium feeling cabins, but the disappointing part is that it's an older Audi design, which started out in the third-generation A3, launched in 2013, and still exists on the Q2, even though most Audi models, including the Q3, have the new interior design. This would bug me if I was thinking about buying a Q2. 

Have you thought about a Q3? It’s not that much more in price, and it’s a tad bigger, obviously. 

The Q2 is tiny, at 4208mm end to end, 1794mm wide and 1537mm tall. The SQ2 is longer at 4216mm long, 1802mm wide and 1524mm tall.  

The new-generation GLA 45 S has grown in all dimensions compared with its predecessor, making it much roomier and more practical than before.

For reference, it measures 4438mm long, 1849mm wide, 1581mm tall and features a 2729mm wheelbase, but still sports a roomy cabin for four adults, especially in the front seats.

Storage options include decent door pockets that will accommodate large bottles, a deep centre storage bin, smartphone cradle that doubles as a wireless charger, and two cupholders.

Being a small SUV, the rear seats also afford plenty of room for occupants, with more than enough space for head, shoulders and legs – even with the front seat adjusted to my 183 cm (6'0") frame.

There are decent door pockets, air vents, and USB-C ports that should keep passengers happy on long trips, but the GLA 45 S doesn’t have a fold-down armrest or cupholders for the rear seats.

The boot, however, is where the GLA 45 S really starts to make a case for itself compared to the A 45 S.

The boot boasts 435 litres of volume, and can expand to a massive 1430L with the rear seats folded – making it about 15 per cent bigger than the A 45 S – while the higher load height should make loading and unloading groceries a bit easier. 

A downside of the GLA’s tech-focused interior, though, is that all the USB ports are now USB Type-C, meaning you’ll likely have to carry around an adapter to use your old cables.

Mercedes is generous enough to include one with the car, but given most device chargers are still USB Type-A, it is something to be aware of. 

The Q2 is basically a current model Audi A3, but more practical. I’ve lived with the A3 Sedan and Sportback and while rear legroom is just as confined in those as it is in the Q2 (I’m 191cm and need to squish my knees behind my driving position) getting in and out is easier in the SUV, with its elevated ride height and taller door apertures.

The easier access helps enormously when helping kids into their child seats. In an A3 I need to kneel on the footpath to be at the right level to put my son into the car, but not with the Q2.

The boot space of the Q2 is 405 litres (VDA) for the front-wheel-drive 35 TFSI and for the SQ2 it’s 355 litres. That not bad, and the large hatch makes for a big opening, which is more practical than a sedan’s boot.

Inside, the cabin isn’t enormous, but rear headroom is good, thanks to the fairly high roof.

Cabin storage isn’t terrific, although the front door pockets are big and there are two cupholders up front.

Only the SQ2 has USB ports in the back for rear passengers, but all Q2s have two USB ports up front for charging and media – plus all have wireless charging for phones.

The Q2 entry grade is the 35 TFSI and it lists for $42,900, while the 40 TFSI quattro S line is $49,900. The SQ2 is the king of the range and lists at $64,400.

The SQ2 has never been to Australia before, and we’ll get to its standard features in a moment.

Aussies have been able to buy a 35 TFSI or 40 TFSI since the Q2 arrived in 2017, but now both have been updated with new styling and features. The good news is the prices have only gone up by a few hundred bucks,  compared to the old Q2.

Standard on the 35 TFSI are LED headlights and taillights, LED DRLs, leather seats and steering wheel, dual-zone climate control, Apple CarPlay and Android Auto, eight-speaker stereo with digital radio, front and rear parking sensors and a rear-view camera.

That was all standard on the previous 35 TFSI, but here’s what’s new: an 8.3-inch media screen (the old one was seven inches); a proximity key with push button start (great news); wireless phone charging (brilliant), heated exterior mirrors (more helpful than you’d think), ambient interior lighting (aww… pretty); and 18-inch alloys (heck yes).

The 40 TFSI quattro S line adds sports front seats, drive-mode selection, a power tailgate, and paddle shifters. The previous one had all that, too, but this new one has the sporty S line exterior body kit (the previous car was just called Sport not S line).

Now, the 45 TFSI quattro S line may appear  not to get much more than the 35 TFSI, but the extra money is getting you more grunt and an awesome all-wheel-drive system –  the 35 TFSI is front-wheel-drive only. If you love driving and can’t afford the SQ2, then $7K extra for the 45 TFSI is absolutely worth it.

If you have saved all your pennies and the SQ2 is what you’re zeroing in on, then here’s what you get: Metallic/pearl effect paint, 19-inch alloys, matrix LED headlights with dynamic indicators, the S body kit with quad exhaust, sports suspension, Nappa leather upholstery, heated front seats, 10-colour ambient lighting, stainless-steel pedals, auto parking, a fully digital instrument cluster, and a 14-speaker Bang & Olufsen stereo.

Of course, you get an incredible high-output four-cylinder engine, too, but we’ll get to that in a moment.

Powering the Mercedes-AMG GLA 45 S is a 2.0-litre turbocharged petrol engine, outputting a staggering 310kW/500Nm.

This means the new car jumps up 30kW/25Nm compared to its predecessor, explaining (at least in part) the price jump.

The GLA 45 S is also the top-spec version globally. The 285kW/480Nm GLA 45 which is available overseas would be more directly comparable to the old car.

The engine is also the most potent production 2.0-litre on earth, and is shared with the A 45 S and CLA 45 S.

Paired to the engine is an eight-speed automatic transmission, which sends drive to all four wheels via Mercedes’ '4Matic' system.

As a result, the GLA 45 S will accelerate from 0-100km/h in a frighteningly quick 4.3 seconds, and carry on to an electronically limited top speed of 265km/h.

This is 0.4s slower than its A 45 S sibling, in part due to its heftier 1807kg weight.

There are three grades and each has a different engine. 

The 35 TFSI has a new 1.5-litre four-cylinder turbo-petrol engine making 110kW and 250Nm; the 40 TFSI has a 2.0-litre turbo-petrol four making 140kW and 320 Nm; and the SQ2 has a 2.0-litre turbo-petrol as well, but it puts out a very impressive 221kW and 400Nm.

The 35 TFSI is front-wheel drive, while the 45 TFSI quattro S line and SQ2 are both all-wheel drive.

All have a seven-speed dual clutch automatic transmission – nope you can’t get a manual. There are also no diesel engines in the line-up.

I drove all three cars and, from an engine perspective, it’s like turning the ‘Smile Dial’ up from Mona Lisa in the 35 TFSI, to Jim Carrey in the SQ2, with Chrissy Teigen in between.

Official fuel consumption figures for the GLA 45 S are pegged at 9.6 litres per 100km thanks in part to an engine start/stop system.

We managed 11.2L/100km after a few days of testing around Melbourne’s inner city and winding country back roads, but those with lighter feet will no doubt come closer to the official figures.

A performance SUV that can ferry kids and groceries, out accelerate  nearly everything else on the road, and sip around 10L/100km? That’s a win in our book.

Audi engines are superbly modern and efficient – even its monster V10 can shut down cylinders to save fuel, and so can the new 1.5-litre four-cylinder engine in the 35 TFSI. Audi says that over a combination of urban and open roads, the 35 TFSI should use 5.2L/100km.

The 40 TFSI is thirstier at 7L/100km, but the SQ2 demands a bit more at 7.7L/100km. Still, not bad. 

What’s not good is the lack of a hybrid, PHEV or EV variant of the Q2. I mean the car is small and ideal for the city, and therefore a perfect candidate for an electric version. Not having a hybrid or EV is why the Q2 model range doesn’t score well for its overall fuel economy.

If the bespoke styling wasn’t enough of a giveaway, all it takes to realise you are behind the wheel of something special is to turn on the GLA 45 S.

The prodigious engine is fantastic in the A 45 S and CLA 45 S and is no different here.

With peak power coming in at a heady 6750rpm and maximum torque available from 5000-5250rpm, the GLA 45 S likes to rev and makes it feel a little like a naturally aspirated engine in character.

Don’t get us wrong, once the boost becomes available, you will feel that shove into the back, but it’s great that Mercedes has made the engine perform a little more predictably.

Paired to the engine is a smooth shifting eight-speed dual-clutch automatic transmission, which is one of the better versions I've experienced.

Many DCT bugbears, such as jerkiness at low speeds and clunkiness when putting into reverse, aren’t apparent here, and the transmission is up to the task when puttering around town or when driving spiritedly.

Speaking of which, the GLA 45 S’ different drive modes will easily change its character from tame to wild, with available options including ‘Comfort’, ‘Sport’, ‘Sport+’, ‘Individual’ and ‘Slippery.’

Each mode will tweak the engine response, transmission speed, suspension setting, traction control and exhaust, while each can also be mixed and matched in the ‘Individual’ drive mode.

However, a missing feature for the GLA 45 S that is found in its A 45 S and CLA 45 S siblings is a drift mode.

Sure, how many small SUV owners are going to take their car to a track to make use of it, but it still would have been nice to have the option.

With three levels of suspension setting, though, the GLA 45 S offers enough variability to be comfortable around town and soak up the bumps thanks to its long suspension travel, while also switchable for a more involved, driver-focused feel.

The GLA 45 S might never corner as hard or fast as its A45 S sibling, but being an SUV brings its own unique set of plus points.

When it comes to the driving part, Audi can almost do no wrong – everything the company makes, whether it’s low powered or rip-your-face-off fast, has all the ingredients for engaging driving.

The Q2 range is no different. The entry-grade 35 TFSI has the least grunt and, with its front wheels pulling the car along, it’s the only one in the family that’s not blessed with all-wheel drive, but unless you’re doing laps at a track you’re not going to be wanting more power. 

I drove the 35 TFSI for more than 100km on the launch, through the country and into the city, and in all situations, from overtaking on highways to merging and slow traffic, the most affordable Q2 performed well. That 1.5-litre engine is responsive enough and the dual-clutch transmission changes swiftly and smoothly. 

Superb steering and good visibility (although that rear three-quarter view is slightly obstructed by the back pillar) makes the 35 TFSI easy to drive.

The 45 TFSI is a good mid-point between the 35 TFSI and the SQ2 and comes with a very noticeable bump in oomph, while the extra traction from the all-wheel drive is a reassuring addition. 

The SQ2 isn’t the hardcore beast you might think it is – this thing would be super easy to live with daily. Yes, it has firm sports suspension, but it’s not overly hard, and that engine, which nudges almost 300 horsepower, doesn’t feel like a Rottweiler on the end of a leash. If anything, it’s a Blue Heeler that loves to run and run, but is happy to take it easy and get fat.  

The SQ2 is my pick of the bunch, and not just because it’s quick, agile, and has an intimidating growl. It’s also comfortable and luxurious, with sumptuous leather seats.  

The Q2 was given the maximum five-star ANCAP rating when it was tested in 2016, but by 2021 standards it is light on advanced safety tech.

Yes, AEB with pedestrian and cyclist detection is standard on all Q2s and the SQ2, and so is blind-spot warning, but there’s no rear cross traffic alert or reverse AEB, while lane-keeping assistance is only standard on the SQ2, along with adaptive cruise control.

For a car that will most likely be purchased by younger people, it doesn’t seem right that they’re not being protected as well they would be in more expensive Audi models.

For child seats, there are two ISOFIX points and three top-tether anchor mounts.

A space-saver spare is under the boot floor.

Like all new Mercedes-Benz models, the GLA 45 S comes with a five-year/unlimited kilometre warranty with five years of roadside assist – the benchmark in the premium car space.

Service intervals are every 12 months or 20,000km, whichever occurs first, and the first five services are available to purchase for $4300.

This actually makes the new GLA 45 S cheaper to maintain over its first five years than the outgoing car, which costs $4950 over the same time period.

The pressure for Audi to move to a five-year warranty must be hugely intense, with Mercedes-Benz offering one, along with pretty much every other mainstream brand. But for now, Audi will only cover the Q2 for three years/unlimited kilometres.

As for servicing, Audi offers a five-year plan for the Q2 costing $2280 and covering every 12-month/15000km service over that time. For the SQ2, the cost is only a fraction higher at $2540.
