Mercedes-Benz GLC-Class vs Audi Q2

What's the difference?

Like I said right from the start, this new, hybrid version of the AMG GLC63 is technically superior to the model it replaces in every meaningful way. It is faster, more powerful and more fuel efficient and therefore a better performance SUV than the model it replaces.

Is it a better model than the one it replaces? Ultimately that will come down to how much stock you put into the soundtrack and your feelings on an AMG not powered by a V8 engine.

Because if you can see past that, then the AMG GLC63 is an absolutely fantastic performance SUV. Not only does the new powertrain make it faster in a straight line, but the chassis is very well-balanced, making for an engaging driving experience.

For those who can look past the smaller engine they will be rewarded with an incredibly fast and rewarding-to-drive member of the AMG family.

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 GLC63 is unmistakably an AMG from the moment you first lay eyes on it. That’s thanks to the AMG-specific elements, starting with the grille with vertical strikes and the AMG crest on the bonnet; which is now a signature item for the performance sub-brand.

The GLC63 is also fitted with the Night Package II design kit; this adds a darkened grille and black chrome badging to further enhance its visual appeal.

The AMG-specific alloy wheels and more aggressive stance do mean the GLC63 stands out from the rest of the GLC range, helping it look fast even when it’s standing still.

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.  

Inside the GLC63 is clearly a derivative of the rest of the range, with its C-Class-inspired design and layout, but there’s enough AMG-specific elements to ensure it looks and feels special. This starts with the AMG steering wheel, which comes not only with a thick rim wrapped in Alcantara, but also some AMG special dials to adjust the various performance settings for the powertrain, suspension and transmission.

Then there are the AMG-specific seats, which look good and offer good support for the driver and front seat passenger. The rear seats offer decent space for what is a mid-size SUV, with room enough for two adults or teenagers or three smaller kids.

Those in the back aren’t particularly well looked after though, with only rear air-con vents and small door pockets but no USB charging ports or other small item storage.

The boot is 590 litres, down from 620L in the rest of the range, thanks to the addition of the rear-mounted electric motor. There’s also no room for the temporary spare the rest of the GLC range gets and instead you have to make do with a puncture repair kit.

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.

This is what lies at the heart of the AMG GLC63’s success or failure. As I mentioned at the beginning, the previous generation’s 4.0-litre twin-turbo V8 has been replaced by an F1-inspired plug-in hybrid powertrain.

But don’t think that means AMG is suddenly focused on efficiency over performance. When AMG says the powertrain is inspired by the brand’s success in Formula 1 racing, what it means is the battery and electric motor provides a significant performance boost to support the internal combustion engine, not just save fuel.

To that end the combination of the turbocharged 2.0-litre four-cylinder petrol engine and the rear-mounted electric motor produces an impressive 500kW and 1020Nm. That’s a massive jump over the 375kW/700Nm made by the outgoing V8.

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.

Mercedes makes no secret that the battery is designed for performance, not saving fuel. It only has a 14km EV range but can recharge quickly on the move to provide a power boost when needed.

But despite all that, the GLC63 is actually significantly more fuel efficient than the old V8, using a claimed 7.3L/100km, which is a massive 4.9L/100km improvement over the old model. Although, on our day-long test drive we didn’t manage to come close to that claimed figure and instead saw returns around 11L/100km, albeit after a lot of spirited open-road driving.

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.

Anyone who still believes in the adage ‘there’s no replacement for displacement’ hasn’t driven a modern turbocharged and hybridised engine. The GLC63 is a demonstration of the metaphorical and literal power of modern technology, combining an extremely efficient and potent internal combustion engine with an electric motor to make enormous real-world performance.

To be blunt, the GLC63 feels like a rocketship out of corners, launching with a ferocity and relentlessness the old V8 simply can’t match. It shouldn’t come as a surprise, a mid-size SUV with 1020Nm was always going to have plenty of performance, but even so it’s a shock to the system every time you give the GLC63 full throttle. Officially AMG claims it takes just 3.5 seconds to run 0-100km/h and has an electronically limited top speed of 275km/h - mighty impressive figures for a five-seat mid-size SUV.

To help get all that torque to the road, AMG deploys torque distribution technology that allows for it to be split an even 50/50 front/rear all the way to 100 per cent to the rear tyres.

Other technologies deployed to enhance its handling include AMG Ride Control suspension with adaptive damping and rear-axle steering. There’s also eight AMG Dynamic Select driving modes and four AMG Dynamics settings (Basic, Advanced, Pro and Master), so it’s a complex vehicle that is designed for the enthusiast.

While it’s easy to drive around town, once you get out on the open road you can really get a sense of the GLC63’s performance potential. Beyond just its powertrain the suspension offers good body control and the rear-axle steering helps it feel agile and responsive. 

It’s not perfect though. At times the complexity of the system does lead to some hesitation when you put your foot down. It certainly lacks the linear power delivery of the old V8 and makes for a slightly trickier driving experience at times.

As for the sound, which is one of the biggest elements missing from the V8, Mercedes has added AMG Real Performance Sound, which features a pressure sensor in the exhaust that picks up on the engine note and plays it through the speaker system. It certainly helps make for a louder, more noticeable engine noise, but it still sounds more like an A45 than the previous GLC63 and for many would-be buyers, that’s a major turn-off.

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.

The GLC63 is covered by Mercedes Australia’s usual five-year/unlimited kilometres warranty.

As for maintenance, Mercedes offers service plans, spanning three to five years. Three years will cost you $5025, $6455 for four years and five years is priced from $7180. Servicing intervals are 12 months or 20,000km, whichever comes first.

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.
