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 GLS-Class
If you’re in the market for a full-size, seven-seat, luxury SUV you’re obviously living life large. Big family, lots of friends, dogs and cats, and heaps of activity - horses, boats, camping?
You’re not in the BIG big-buck orbit of the Bentley Bentayga, nor are you ready to plug into the electrified matrix with the Tesla Model X.
You’re aiming at a six-figure bullseye between $130,000 and around $150,000. On a three-year novated lease, somewhere around three grand a month.
Which takes in the chunky Lexus LX and German ‘Big Three’ - the Audi Q7, BMW X7, and this car, the new, third-generation, Mercedes-Benz GLS.
Mercedes-Benz Australia invited us to experience the car on a launch drive across city, suburban and rural roads.

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.
Mercedes-Benz GLS-Class8/10
The new GLS is everything you’d expect of a Mercedes-Benz with an S in its name. Luxury, performance, space, and in this case, thoughtful practicality. A super-capable, super-sized family truckster with the lot.
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 GLS-Class7/10
Launched globally in mid-2019, Merc describes the GLS as the S-Class of SUVs, which is apt given its 5.2m length, 2.5-tonne mass, and ultra-premium specification.
As mentioned, the GLS is big; a step up from the already substantial model it replaces. Built with the US market in mind, in fact it’s produced in Tuscaloosa, Alabama, it’s more than five metres long, close to two metres wide, and over 1.8m tall. And there’s more than three metres between the axles, a 60mm wheelbase increase over the previous model.
And despite the size of the canvas, the Benz design team has managed to make the GLS look like a modern Merc. Signature elements include obvious ones like the slatted grille with a couple of three-pointed stars on the nose.
But there’s also, the carefully chiselled twin ‘power dome’ bonnet, scowling LED headlights and vents to aid front brake cooling and smooth aero performance around the front of the car.
The big beast’s off-road intent is highlighted by extensions around the wheelarches, with big optional 22-inch rims sitting underneath. The fact they look right-sized for the car speaks volumes about its scale.
The racy AMG Line package is standard, and a recess and pronounced character line, tightening the lower waistline is a familiar Merc treatment, plus alloy roof rails toughen the look while dialling up practicality.
The rear is relatively simple, borderline generic, with tapered tail-lights offering the only strong whiff of design personality. But believe it or not, thanks to careful detail sculpting of the body, and smoothing underneath the car it boasts a drag figure of Cd 0.32. Outstanding aero performance for a large SUV.
The driver and front passenger are presented with a sweeping dashboard dominated by twin 12.3-inch digital screens, one primarily covering the instruments, and the central screen managing the MBUX media system, including audio, nav, phone integration, car set-up, and more, plus ‘Hey Mercedes’ voice control.
The overall feel is simple, and restrained, yet massively confident, with a subtle colour palette, large squared-off elements defined by brushed metal finishes, and an obvious, intense attention to detail, from the haptic controls to the beautifully finished, multi-function steering wheel.
And the standard Burmester audio system includes a two-way in-car communication function that subtly amplifies the driver and front passenger’s voices for those in the third row, and vice versa. Sheer genius.
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.
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 GLS-Class9/10
Space is obviously a critical factor here, and no surprise there’s copious amounts of it inside the GLS.
Front seat passengers enjoy plenty of breathing room, without feeling remote from one another, and there’s lots of storage in the shape of a large lidded box/armrest between the seats, a decent glove box, two big cupholders and jumbo door pockets with room for large bottles.
There’s one data-enabled USB port in the front, two charge-ports in the second row, and four in the third row. Shouldn’t be any complaints about powering mobiles, tablets or games.
The second row feels every millimetre the SUV limo. Simply getting in and out is made easier because an auto lowering function drops the car 25mm when one of the doors is opened.
I was able to sit behind the driver’s seat set for my 183cm position with heaps of head and legroom on offer. And there’s an extra 10cm of electrically adjustable travel to play with if those in the third row agree.
The fold-down centre armrest features a lidded storage tray and twin pop-out cupholders. There are netted pockets on the front seatbacks, and again, the door bins are big enough for large drink bottles.
Three adults across the rear is a breeze, there’s climate control ventilation, and a huge glass sunroof is standard. Rather than asking ‘Are we there yet?’ the kids will be disappointed when you arrive!
Then there’s what the Cleary family refers to as ‘the way back seat.’ A pair of third row seats for the lucky kids that get to inhabit their own little world. Getting in and out is relatively civilised thanks to electric slide and tilt for the second row seats, and space is generous. I could sit comfortably, so the kids will be all smiles.
With all seats upright cargo capacity is enough for a seven-person day trip (355L VDA). Press the button to fold the 50/50 split-fold third row down and your options expand substantially (890L). And with 40/20/40 split-folding second row lowered, transportation of a full, three-ring circus is on the cards (2400L). Overall, more space than the arch enemy BMW X7.
Plus, the ability to lower the car 50mm thanks to the standard air suspension makes life even easier. And one button lowers the second and third rows at the same time.
The spare is a collapsible space-saver, and towing capacity for a braked trailer is 3500kg, with a tow ball weight of up to 140kg. The ESP system also features a trailer stabilisation function that counters oscillation with “braking intervention.”
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 GLS-Class8/10
The GLS launches in Australia with two models, the turbo-petrol GLS 450 4Matic at $146,500, before on-road costs, and the turbo-diesel GLS 400 d 4Matic at $153,300.
Specification is identical across the two variants, and when you’re competing against the likes of the Lexus LX570, Audi Q7 and BMW X7, as you might expect the list of standard features is lengthy.
Aside from the comprehensive suite of safety tech, covered in the Safety section below, the GLS equipment list includes, 21-inch alloy rims, adaptive high beam assist, air suspension, alloy roof rails, AMG body kit, a huge panoramic sliding glass sunroof, privacy glass from the B-pillar back, auto tailgate, keyless entry and start, rain-sensing wipers, cruise control, LED headlights, and power closing doors.
The power closing doors are a big plus for parents not wanting to disturb kids nodding off in the car, with the soft-touch function drawing the door in for the last few millimetres to an almost silent close.
Inside there’s ambient lighting (64 colours), strategically placed open pore oak wood trim, 13-speaker/590-watt Burmester surround sound audio, electric folding second and third row seats, a head-up display, ‘Mercedes-Benz’ branded illuminated sills, leather seat upholstery (‘Artico’ faux leather on the dash and doors), multi-adjustable electric seats in the front and second row (memory in the front), electrically adjustable steering column, leather-trimmed multi-function steering wheel, and five-zone climate control.
The multi-media system is spectacular, incorporating the twin 12.3-inch digital screens, the central media unit managing nav, digital radio, mobile device connectivity, Apple CarPlay and Android Auto, plus vehicle tracking. There are also remote vehicle status functions (door locking, valet parking, etc), global search (Amazon Alexa, Google Home, Yelp, and Trip Advisor), and a wireless device charging pad.
The basket of goodies can hold its head high in this part of the market, so the value equation stacks up well.
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 GLS-Class8/10
There are two engines on offer. The 3.0-litre (M256) in-line six-cylinder turbo-petrol GLS 450 4Matic, and the 2.9-litre (OM656) in-line six-cylinder turbo-diesel GLS 400 d 4Matic.
The all-alloy, twin-scroll single-turbo petrol engine delivers peak power of 270kW from 5500-6100rpm, and maximum torque of 500Nm across a broad plateau from 1600-4500rpm. It also features a 48-volt electrical system driving the ‘EQ Boost’ set-up, able to deliver an extra 16kW/250Nm for short periods. The integrated starter-generator also enables energy recuperation.
Although the all-alloy, twin-turbo diesel features variable valve lift it gives some ground on power, offering up 243kW between 3600-4000rpm, but torque is a solid whack, with 700Nm on tap from 1200-3000rpm. Worth noting, that to minimise emissions this engine features a “selective catalytic reduction converter” in the exhaust, which brings with it the use of an ‘AdBlue’ reducing agent. The separate AdBlue tank has a capacity of 31.6 litres.
The nine-speed auto transmission is the same in both versions, although the diesel has a slightly lower final drive ratio.
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.
Mercedes-Benz GLS-Class8/10
Claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle for the GLS 450 is 9.2L/100km, the more frugal GLS 400 d trimming that to 7.7L/100km. The petrol 450 emits 210g/km of CO2 in the process, the diesel 400d dropping that slightly to 202g/km.
Stop-start is standard, you’re looking at premium unleaded for the 450 GLS, and you’ll need 90 litres of dinosaur juice to full the tank on both models.
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.
Mercedes-Benz GLS-Class7/10
Merc claims the GLS 450 will sprint from 0-100km/h in 6.2sec, and the 400 d in 6.3sec. Not hanging around for a 2.5 tonne mothership. But the standout is the 400 d’s torque. All 700Nm of it available from just 1200rpm to 3000rpm; right in the mid-range sweet spot.
The nine-speed auto transmission is smooth yet responsive, with paddles on the wheel for manual shifts when you want to pick the ratio. The combination of effortless grunt and the nine-speeder keeping things on the boil is an impressive one.
Suspension is by double wishbones at the front and multi-links at the rear, and while you can feel the weight in cornering, the standard Airmatic air suspension (which does away with steel springs) is superb in terms of ride comfort and body control.
We took a deep breath and pushed enthusiastically through a series of sweeping corners and the fat (285/45 fr - 325/40 rr) Continental ‘PremiumContact 6’ rubber wrapped around our car’s (optional) 22-inch rims gripped hard.
The ‘4Matic’ all-wheel drive system also seamlessly shuffles torque between the front and rear axles (theoretically up to 100 per cent in each direction).
Merc has put extra focus on body rigidity, the tuning of engine and suspension mounts, and sound absorption, and it shows. The GLS 400 d is beautifully refined on the highway. A neat touch is the car automatically lowering 15mm at motorway speeds or when ‘Sport’ mode is selected.
Steering is electromechanically assisted, and Merc says the front suspension geometry has been revised to minimise vibration through the wheel. And yes, feedback is minimal, but unfortunately so is road feel with only a general connection between your hands on the wheel and the front tyres on the bitumen.
When you’re steering a large beast like this, often with something substantial hitched to the back, you want to know braking performance is up to the task, and the GLS’s big ventilated discs all around deliver reassuringly strong stopping power, with nice, progressive pedal feel to boot.
The seats are adjustable six ways to Sunday, but beyond that they’re comfortable and supportive, even over long stints behind the wheel.
We stayed on the bitumen, because, let’s face it, that’s where this car will spend 99.9 per cent of its time, with the exceptions of the boat ramp, a ski weekend or pony club.
For those special occasions the optional ‘Off-road engineering package’ adds a low-range transfer case, inter-axle locking, hill descent control, and under body armour for more serious work.
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 GLS-Class10/10
At the time of this launch drive the GLS hadn’t been safety assessed by ANCAP, but you could make a small wager, like every penny you have to your name, that it will score a maximum five stars.
The expected active features are there, including ABS, ASR, and ESP, with additional tech including ‘Active Blind-Spot Assist’, ‘Active Brake Assist' (Merc-speak for AEB), active lane keeping and lane change assist, ‘Adaptive Brake’, ‘Attention Assist’, ‘Evasive Steering Assist’, ‘Parktronic’ (active parking assist with 360-degre camera), rear cross-traffic alert, traffic sign assist, and a tyre pressure warning system.
Then, if all that isn’t enough to avoid an impact the GLS is equipped with nine airbags (front and pelvis side for driver and front passenger, side for outer rear seat occupants, full-length curtain, and a driver’s knee bag), an active bonnet to minimise pedestrian injuries, and the ‘Pre-Safe Plus’ (flashes rear hazards to warn drivers closing too quickly from behind, tightening the belts at the same time, and locking the brakes if the GLS is stationary with a rear impact imminent).
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 GLS-Class7/10
The Mercedes-Benz range is covered by a three year/unlimited km warranty, which, like Audi and BMW continues to lag behind the mainstream market where the majority of players are now at five years/unlimited km, with some at seven years.
On the upside, Mercedes-Benz ‘Road Care’ roadside assistance is included in the deal for three years.
Service is scheduled for 12 months/25,000km (whichever comes first) with pricing available on an 'Up-front' or 'Pay-as-you-go' basis.
As a guide, service pricing for the outgoing GLS is set at $2600 per service (up-front) and $3250 (PAYG), a saving of $650 a pop. Fourth and fifth services are also available for pre-purchase ($3550 and $4900).
