Summary
Audi SQ7
The Audi Q7 has come in for its second facelift as it enters its ninth year of production while the younger Q8 is in for its first refresh.
But these two aren't like the Mitsubishi ASX and Eclipse Cross pair; Audi's MLB underpinnings were cutting edge at their launch 2015 and remain stand-out in the class with advanced suspension and chassis tech, connectivity and refinement.
A host of small visual and performance tweaks aim to make the range-topping SQ7 we're driving even better. But should you make the sensible seven-seat decision or go a little rogue and choose the sloping-roofed SQ8?

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 SQ77.9/10
There are newer options than the current Audi SQ7 and SQ8, including those which use the same platform, but don't write these luxury large SUVs off just yet.
It's a rare thing that a vehicle costing $200,000 has an air of pragmatism about it, but the SQ7 does. Its sensible leather upholstery, decent practicality, towing capability and near-excess of interior space make it a great family wagon.
As a counterpoint, the sharper looking SQ8 has minimal trade-off in comfort and interior room (at least for five) and is the kind of statement piece you'd expect for the price — especially in one of its loud paint colours.
Whichever way you leap, it's true that while the SQ7 and SQ8 are ageing, they are doing so gracefully and remain a superb option in this segment.

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 SQ7
If you're getting an SQ7, you'll want to tick the 'Black Pack' box because otherwise there are a lot of high-gloss silver details, especially at the rear that don't suit this tall and slightly awkward SUV.
The SQ8 is more convincing, appearing wider on the road with its new 'singleframe' grille design seemingly sucking it even closer to the tarmac like some kind of overgrown Audi RS3.
Both get an attractive new 2D design for the Audi rings and L-shaped grille details. These aid the SQ7's front end which is more muscular and purposeful than before.
The attractive lights have moved higher up the front end for enhanced presence, too. You get Matrix LEDs as standard but these candles are the hardcore HD Matrix items that feature laser light for further even longer light throw at night. They are simply awesome.
Fresh 22-inch alloy wheels and minor changes to badges finish off the exterior treatment for both cars.
The SQ8's bold specification — finished here in 'Sakhir Gold' — sets it apart from other SUVs as the metallic gold paint shimmers in the sunlight. The SQ8 is also available with whopping great 23-inch alloy wheels that you see here.
Inside, both cars share a similar architecture with 10.1-inch touchscreen for the multimedia and an 8.6-inch item below for heating and ventilation settings.Â
The SQ7 is a great example of a design ageing without dating, its confident horizontal lines and well-proportioned cabin features are as attractive as they were at launch, if less impressive than the related VW Touareg's whopping 15-inch screen or the minimalist Range Rover Sport.
Adding to the feeling of quality is that signature Audi smell — a combination of leather and the Sensory Package's perfume, no doubt. The SQ7 keeps a round-bottom steering wheel which remains one of the best in the business, it's just the right size and diameter trimmed with dimpled leather.
Final flourishes include the optional contrast red stitching and seatbelts as well as eye-catching turned aluminium trims.
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 SQ7
The difference between aged and dated is best summed up, though, by the excellent usability of the SQ7's cabin controls.
The separate screen for ventilation, for example, makes it simple to adjust seat or vent temperatures without interrupting the main screen's navigation instruction or other media systems.
When using wireless Apple CarPlay and Android Auto the top screen is entirely devoted to the other software with no remnants of Audi's system. It runs smoothly at all times.
Switching back to Audi's system, and there's a lack of contrast to the dark main screen and navigation. The touch targets are huge, though, and the satisfying click of the haptic feedback is welcome when driving. It seems expensive and natural in a world of feel-free touch operation.
Audi's 12.3-inch digital driver's display remains one of the best in the business. Legible and customisable with bespoke sport modes and the ability to show a full-size map, if you wish.
You can keeping devices charged with a wireless pad or there are two USB-C ports under the cushy centre armrest. A 12-volt socket is also available, and two more charge points are found in the back.
If there's one criticism in the front, it's the fairly limited storage. The door bins are big enough for a 600mL bottle but not much more and beneath the armrest the tray is shallow. The only other storage spots are the two cupholders which are the perfect size for a small take-away coffee.
While on the critiques, the drive mode selector is awkwardly hidden near the passenger below the touchscreen.
The seats are amazingly comfortable with ample support and power adjust for everything, including under-thigh length and bolsters. Several massage programs can be accessed through the menus, too.
Continuing the comfortable seating, the SQ7's second row is capacious with plenty of head, leg and toe room even for those over 180cm.
The bench slides forwards and backwards manually and the backrest is adjustable. A fold-down armrest contains two more small cupholders, and there are two separate climate zones, two vents and heated outboard seats.
However, folding and unfolding the second row is a bit complex and quite heavy work with a strange mix between electric and manual movement to access the third row — a Nissan Pathfinder does this better.
Once back there, the third row is passable for adults providing the second row is slid forward.
There are ISOFIX ports and top tether anchors for both power-deployed third row seats, so you can fit up to five children's seats in an SQ7.
The SQ8's second row is still generous but you do lose a small amount of headroom owing to the sloping roof design.
You also sacrifice some boot space, at 608L with five seats and 1755L with the second row folded. That's still a lot but the spacious SQ7's 793L/1921L figures are even better and 295L with all seven seats up is respectable. Both have sturdy 40/20/40 split-fold rear seats.
As the vehicles are equipped with air suspension, owners can raise or lower the boot floor to make it easier to load bulky objects if needed. A power tailgate is standard on both models.
A retractable luggage cover, netted pocket, boot lights and some underfloor storage complete the boot, however both cars lack a spare tyre of any sort. A tyre inflation kit is included.
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 SQ7
Audi's range of Q7 and Q8 large SUVs starts at $117,284 for the 45TDI and there's a plug-in hybrid version from $152,284, both before on-road costs. The flagship SQ7 and SQ8 are $174,815 and $178,815, respectively.
The pair is a rare example of a discounted new car, albeit by a slim $585, so you'd expect these behemoths to offer comprehensive standard specification.
Features such as 22-inch alloy wheels, ambient interior lighting, soft close doors, power-adjust heated and ventilated seats, quad-zone climate control, 'Valcona' leather upholstery, a 17-speaker Bang & Olufsen sound system, full-length sunroof, navigation and a head-up display are included.
Naturally, options are available in packs and standalone choices with all vehicles we drove featuring at least one of the expensive box-ticks.
The 'Sensory Pack' seems a logical choice, bundling a 23-speaker, 1920-watt sound system with raising tweeters, 'Dinamica' headlining, massage seats, heated rear seats, Audi's air ioniser and interior perfume, extended leather upholstery and rear sun shades for $14,400.
Another major option is the $10,900 'Dynamic Package' with active roll stabilisation and Quattro Sport rear differential.
Stand-out stand-alone options include HD Matrix LED and Laser headlights combined with customisable OLED rear signatures ($3950) and the black exterior styling packages ($1850, or $2550 for the Plus version).
The as-tested price for the tow pack-equipped ($1500) 'Daytona Grey' car we spent most time in was rather high at $209,215 before on-road costs — that's over $30K worth of extras.
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 SQ7
The SQ7 and SQ8 both use a 4.0-litre twin-turbo 'hot vee' V8 petrol after the diesel SQ7 was abandoned in mid-2022.
It is the same engine you'll find in just about every application of this MLB platform, including the Porsche Cayenne, Bentley Bentayga and Lamborghini Urus — though it makes more power elsewhere.
In Audi's two medium-sporty SUVs it produces 373kW at 5500rpm and 770Nm between 2000-4000rpm.
In practice, it's a swelling, punchy engine without much top-end sparkle — though 4.1 seconds to 100km/h is nothing to scoff at.
The V8 also produces a rather splendid soundtrack, striking the right balance between Detroit burble and motorsport bark for this application.
An eight-speed torque converter auto transmission has been retuned for improved shift logic and it remains buttery smooth. It's pleasing enough just manoeuvring slowly around a car park, where you can feel just well calibrated the long travel throttle and transmission logic are.
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 SQ7
With 2340kg to heave around, not even the 48-volt mild hybrid system can save the SQ7's fuel consumption — it's a thirsty beast.
The rated ADR combined cycle (urban, extra-urban) figure is 11.8L/100km and indulging in the ample performance resulted in 16.5L/100km on the trip computer. The SQ8 was much the same.
The SQ7 is certified to tow up to 3500kg (braked), equal to a Toyota LandCruiser or Nissan Patrol.
A fairly large 85L tank gives the SQ7 a theoretical driving range of around 720km from a fill-up. Naturally, 98 octane unleaded is required.
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 SQ7
Our drive loop started in South-East Sydney where the SQ7's burbly V8 and air suspension fitted right in, easily soaking up the worst of the concrete expansion joints and sharp-edged potholes.
It is a joy to waft around in the refined SQ7 with its remarkably good vision out the front and back (with 360-degree cameras to help elsewhere). Standard rear-wheel steer allows the back tyres to rotate up to 5.0 degrees, giving the 5072mm long SQ7 a better turning circle (12.5m) than a Q3 small SUV.
Its driven home further by the excellent drive mode customisation. Along with the standard programs, you can set an 'Individual' mode up with various selections for the suspension, steering, powertrain response and exhaust noise.
Following the SQ7, our time in the SQ8 took in some more twisting roads and the combination of 23-inch alloys with firmer suspension settings meant that, even in 'Comfort', 'Auto' or 'Balanced' drive modes, the coupe-styled model had a busier ride.
Both SQ7 and SQ8 featured 'Sport' adaptive air suspension, sitting 15mm lower than normal with the ability to drop the ride height up to 40mm in 'Dynamic' mode or raise it 50mm in lift mode to get out of sticky situations.
Audi chose not to specify the Dynamic pack on the SQ8, though, and the difference is noticeable compared to the SQ7. The coupe SUV rolls a little more in hard cornering and doesn't engage the rear end in quite the same way.
Back in the SQ7, turn in may feel a little less sharp owing to the taller height but the active roll stabilisation and Quattro electronically-controlled limited-slip differential splitting power between the two rear wheels makes for a more confident vehicle with better punch out of corners.
Grip is prodigious and the SQ7 is always in control with 285/35R22 Bridgestone Turanza T005 tyres.
A 2.4-turn lock-to-lock steering system is well-judged, remaining light in Comfort but adding enough weight and precision in Dynamic.
The brakes — 400mm front rotors clamped by six-piston calipers with optional ceramics — are reassuring and feel Autobahn ready.Â
The Audi SQ7 with Dynamic Pack is like an Olympic swimmer that's put on some kilos and had a few kids but can still gap his teenage son in a 50-metre freestyle race.
This is perhaps the perfect expression of Audi's 'S' models USPs, being totally normal when pottering despite huge reserves of talent.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 SQ7
The Audi SQ7 is currently unrated by local ANCAP safety authority but Euro NCAP awarded a Q7 50TDI a maximum five stars in 2019.
It features eight airbags, adaptive cruise control, lane-keep assist, blind-spot monitoring, rear cross-traffic alert, surround-view monitor and exit-warning system to stop occupants dooring cyclists.
The adaptive cruise control is smooth and natural, although we found the lane-keep and lane-trace programs to be a little overbearing. Both can be easily disabled by holding the button at the end of the indicator stalk for about five seconds.
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 SQ7
Audi recommends SQ7 and SQ8 owners bring their car in for a service every 12 months or 15,000km.
Service pricing is not cheap, with a five-year package costing $4600 for either model. For reference a basic service plan for a BMW X5 costs $3450 for five years.
Audi has moved to a five-year, unlimited kilometre warranty with owners able to extend that (for a fee) up to nine years with Audi Advantage. An extra two years of warranty and scheduled servicing costs $4360 for the SQ7 and $4160 for SQ8.
Additionally, customers get access to Audi's loyalty programs with event invitations, ambassador experiences and discounts offers from select partner companies.
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.
