Summary
Audi SQ5
Audi makes some mind-blowing cars. There’s the R8 which comes up to my knees and has a V10, or the RS6 wagon which is like a missile with generous boot space. The model, however, most Audi buyers purchase is the Q5.
It’s a mid-sized SUV, which means it’s basically the shopping trolley in the carmaker’s range. But like all things Audi, there’s a performance version, and that’s the SQ5. Audi launched its updated Q5 mid-sized SUV a couple of months ago and now the revised sporty SQ5 has thundered in.

Mercedes-Benz GLC-Class
Let’s make one thing clear from the very beginning - this new Mercedes-AMG GLC63 S E Performance is technically superior to the model it replaces. Whether it’s actually better or not, is the real question at the heart of the matter.
Why? Because, like the C63 sedan stablemate, AMG has opted to replace the previous model’s 4.0-litre twin-turbo V8 engine with a new 2.0-litre four-cylinder hybrid powertrain. It was a move brought about in part because of increasingly stricter emissions standards in Europe, but also ties-in with the German firm’s success in modern Formula One racing.
While the new hybrid system offers more power, more torque and better fuel economy, as the lukewarm response to the C63 has demonstrated, the hard reality for AMG is that its buyers associate it with V8 and even V12 engines. That emotional pull is hard to replace with logic, even if the new model offers technical superiority.

Verdict
Audi SQ57.5/10
The SQ5 is the best version of a hugely popular SUV, and the turbo-diesel V6 provides a thunderously enjoyable and easy driving experience. The update has brought little in the way of new looks, and practicality remains an area where the SQ5 could be improved, but it’s hard not to appreciate this excellent SUV.    Â
Mercedes-Benz GLC-Class7.7/10
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.

Design
Audi SQ58/10
It might just be me but the Q5 seems to be the best looking SUV in Audi’s range. It doesn’t have the overly large and cumbersome appearance of the Q7, but it has more heft than a Q3. That ‘Tornado line’ which twists itself down the side of the car, with the wheels appearing to push up into the body at the guards, adds to the dynamic look.
The SQ5 looks even more athletic with its S body kit, red brake calipers and 21-inch Audi Sport alloy wheels.
The update has seen the grille restyled to be lower and wider, with a more complex honeycomb design, while the side sill trim has been redesigned, too.
SQ5 colours include, 'Mythos Black', 'Ultra Blue', 'Glacier White', 'Floret Silver', 'Quantum Grey', and 'Navarra Blue.'
The cabin is much the same as before, with the addition of Nappa leather upholstery as standard. While prestigious and well-appointed, the cabin styling has been the same since the arrival of this second-generation Q5 in 2017, and is beginning to show its age.
The SQ5 is 4682mm end-to-end, 2140mm wide and 1653mm tall.
Want more coupe in your SQ5? You’re in luck, Audi has announced that an SQ5 Sportback will be coming soon.
Mercedes-Benz GLC-Class
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.
Practicality
Audi SQ57/10
This mid-size, five-seater SUV could do a better job on the practicality. There’s no third-row, seven-seater option, but that isn’t our main gripe. Nope, the SQ5 is short on rear legroom, and cabin storage isn’t great.
Sure, I’m 191cm (6'3") tall and almost 75 per cent of that is legs, but I can sit pretty comfortably behind my driving position in most mid-sized SUVs. Not the SQ5, which is getting tight back there.
As for cabin storage, yes, there’s a decent-sized console box under the centre armrest and slots for keys and wallets, plus the front door pockets are big, but rear passengers again don’t get the best treatment with small door pockets. There are two cup holders back there, though, in the fold-down armrest and another two up front.  Â
The boot’s 510 litres of luggage capacity is almost 50 litres less than the cargo space of the BMW X3 and Mercedes-Benz GLC.
Four USB ports (two in the front and two in the second row) are useful and so is the wireless phone charger in the dashboard.
Privacy glass, directional air vents for the third row and roof racks that now have cross members are great to see.
Mercedes-Benz GLC-Class
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.
Price and features
Audi SQ58/10
The SQ5 lists for $104,900, making it $35K more than the entry-grade Q5 40 TFSI. Still, the value is good considering this king-of-the-range is loaded with features, including an armful of new ones coming with this update.
New standard features include, matrix LED headlights, metallic paint, a panoramic sunroof, acoustic glazing, Nappa leather upholstery, an electrically adjustable steering column, a head-up display, a 19-speaker Bang and Olufsen stereo, and the roof racks now come with cross members.
That’s along with the standard features which came on the SQ5 previously such as, LED DRLs, three-zone climate control, a 10.1-inch media display, 12.3-inch digital instrument cluster, Apple CarPlay and Android Auto, wireless charging, 30-colour ambient lighting, digital radio, power adjustable and heated front seats, privacy glass, 360-degree view camera, adaptive cruise, and auto parking.
The SQ5 also gets the sporty S exterior body kit with red brake calipers, and the interior also has S features such as sports seats with diamond stitching.
Of course, the SQ5 is more than just a cosmetic pack. There’s sports suspension and that magnificent V6, which we’ll get to soon.
Mercedes-Benz GLC-Class
The power and torque figures aren’t the only numbers that have risen sharply, with the GLC63 clearly impacted by a double whammy of inflation and the usual new-car price rise.
The GLC63 now starts at more than $191,814 for the SUV and $198,415 for the Coupe, which represents a nearly $30k increase over the old V8-powered model, which was priced at $164,600 just two years ago. Even for luxury car buyers that’s a big jump, especially when you’re trying to convince people of the merits of the four-cylinder powertrain.Â
That also means it's more expensive than all of its key competitors, including the BMW X3 M Competition, Maserati’s Grecale and the outgoing, petrol-powered Porsche Macan GTS.
To help explain some of this price increase Mercedes-Benz Australia has opted for a high level of standard specification for local cars. Standard equipment includes 21-inch alloys, AMG composite braking, a panoramic sliding sunroof, a unique AMG steering wheel, power-adjustable sports seats in Nappa leather, a head-up display, dual-zone climate control, wireless smartphone charging and a Burmester 3D Sound system.
Also included is the AMG Track Pace suite, for those who want to unleash their GLC on the racetrack.
There’s also a limited run, AMG Edition 1 Package available too, for an additional $12,900. On the outside you get Manufaktur graphite grey magno paint, foiling with colour gradation and large AMG logo on the sides, an AMG Aerodynamics Package, unique alloy wheels with Edition 1 and AMG branding, yellow brake calipers and an AMG fuel filler cap in silver chrome with AMG lettering.Â
Inside there’s AMG Performance seats, AMG Nappa leather in black with yellow contrasting stitching, AMG illuminated door sills, carbon-fibre AMG trim highlights, yellow seat belts and a unique AMG Performance steering wheel wrapped in carbon-fibre and microfibre.
Under the bonnet
Audi SQ58/10
The SQ5's 3.0-litre, turbo-diesel V6 is a development of the engine that was in the Special Edition SQ5 from the previous model, now producing 251kW from 3800-3950rpm, and 700Nm from 1750-3250rpm.
This diesel engine uses what’s called a mild-hybrid system. Don’t mistake this for a petrol-electric hybrid or a plug-in hybrid because it’s nothing like them, but more an auxiliary system for electrical storage which can restart the engine, which shuts down during coasting.
Shifting gears is an eight-speed automatic, and of course drive goes to all four wheels. Claimed 0-100km/h for the SQ5 is 5.1 seconds, which should be more than enough to help you out when that lane ahead runs out. And towing capacity is 2000kg for a braked trailer.
Is there a petrol variant? There was one in the previous model, but for this update Audi has only released this diesel version so far. That’s not to say a petrol SQ5 won’t appear later. We’ll keep our ear to the ground for you.
Mercedes-Benz GLC-Class
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.
Efficiency
Audi SQ57/10
The Aussie launch didn’t give us a chance to test the SQ5's fuel consumption, but Audi reckons after a combination of open and urban roads the 3.0-litre TDI should return 7.0L/100km. That sounds like ridiculously good economy, but it’s all we have to go on for now. We’ll put the SQ5 through some real-world testing soon.
While the mild-hybrid system does contribute to fuel saving it would be much better to see a plug-in hybrid Q5 on sale in Australia. An e-tron EV version would be even better. So, while the diesel is efficient, consumers need more environmentally sound choices for this popular mid-sized SUV. Â
Mercedes-Benz GLC-Class
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.
Driving
Audi SQ58/10
If I had to choose the best thing about the SQ5, it’s the way it drives. This is one of those cars that feels like you’re wearing it rather than driving it with the way it steers, the smooth eight-speed auto shifts, and the engine responds.
Like a low-flying army helicopter - voomp-voomp-voomp. That’s what the SQ5 sounds like at 60km/h in fourth, and I love it. Even if the sound is enhanced electronically.
But the oomph is completely real. The 3.0-litre, turbo-diesel V6 is a development of the engine that was in the Special Edition SQ5 from the previous model, but it’s better because the 700Nm of torque now comes in lower, at 1750rpm. Power output is also a smidge higher at 251kW.
Just don’t expect the SQ5 to be brutally dynamic, it’s not a Mercedes-AMG GLC 43. Nope, it’s more grand tourer than super SUV with colossal torque and a comfortable ride. It handles impressively, but the SQ5 seems more at home on gentle country roads and highways than switchbacks and hairpins.
My drive route took in only a small amount of city running, but the SQ5’s ease of driving made traffic as stressless as stressful peak hour traffic can be. Â
Mercedes-Benz GLC-Class
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.Â
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.
Safety
Audi SQ58/10
The Q5 was given the maximum five-star ANCAP score when it was assessed in 2017, and the SQ5 carries the same rating.
Coming standard is AEB, although it’s the city-speed type which works to detect cars and pedestrians at up to 85km/h. There’s also rear cross-traffic alert, lane keeping assistance, blind spot warning, adaptive cruise control, auto parking (parallel and perpendicular), 360-degree camera view, front and rear parking sensors, and eight airbags.
For child seats there are two ISOFIX points and three top tether anchor mounts across the rear seat.
Mercedes-Benz GLC-Class
The GLC63 comes standard with a comprehensive suite of safety features including 'Distronic' (Mercedes’ name for adaptive cruise control), 'Active Lane Keeping Assist', 'Blind Spot Assist', 'Traffic Light Assist' and 'Adaptive Highbeam Assist'. It also includes Mercedes’ 'Pre-Safe' accident anticipation system - which pre-tensions the seat belts and will even play a white noise to protect your ears if it senses a crash is imminent.
A parking system that includes a 360-degree camera and active parking assist is also included.
The GLC range was awarded a five-star ANCAP rating in 2022, which pre-dates the latest testing protocols, so doesn’t provide a like-to-like comparison for vehicles tested after that date.
Ownership
Audi SQ56/10
Audi refuses to budge on its three-year/unlimited kilometre warranty, despite other prestige brands such as Genesis, Jaguar, and Mercedes-Benz going to five-year/unlimited km coverage.
As for servicing, Audi offers a five-year plan for the SQ5 costing $3100, covering every 12 month/15000km service over that time, for an annual average of .
Mercedes-Benz GLC-Class
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.
