Audi SQ7 vs Mercedes-Benz GLB-Class

What's the difference?

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.

Note: CarsGuide attended this event as a guest of the manufacturer, with accommodation and meals provided.

The new GLB is a worthy successor to the original. It has retained everything that made it such a unique proposition but improves where it counts - interior space and comfort, in-car and safety tech, standard features, powertrain, ride quality and, importantly, value-for-money.

The EV is the pick of the powertrains and while I didn’t get to drive it, the GLB250+ is the best value.

Servicing is expensive and the standard glass roof is a bugbear but if you can cope with those things, the boxy GLB is a terrific smallish family SUV.

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. 

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.

The original first-generation GLB was a standout when it comes to exterior design. It was boxy, upright and unlike anything else in the premium SUV segment. If you wanted a conventional Mercedes SUV you could opt for the smaller, bubble-shaped GLA or the larger, more sophisticated GLC.

But the GLB occupied its own space. Thankfully Benz has largely stuck with the script for the second-gen GLB, but they’ve modernised it.

Built on the new Mercedes Modular Architecture (MMA), the GLB is a full 98mm longer, has a 50mm longer wheelbase, is 27mm wider and 14mm shorter. And it does look noticeably lower to the ground compared to the old model.

While the square silhouette remains, Benz’s latest design direction is seen everywhere. The front end is more rounded now and has a large gaping low-set grille with an LED light bar running the width of the bonnet. It’s an acquired taste but I prefer the previous GLB face.

The rear is a much better angle for the GLB. Looking at it directly from the rear, it has pronounced shoulders that give it a lovely muscular look, and the curved tail-lights are a highlight.

Benz is leaning into its brand in a bid to stand out in an increasingly competitive global market. It’s doing this by using the iconic three-pointed star as a motif in the head and tail-light cluster, as well as the grille which is illuminated for some grades. I’m not sold on that element as it feels a bit over the top, but at least you won’t get confused about what brand of car it is.

Another design element I’m not sold on is the pop-out door handles. With car companies finding better solutions for handles, this seems out of touch.

Inside, everything feels upright. The integrated glass dash panel spans the width of the cabin, while brushed aluminium panels also feature. The signature Benz seat adjuster switches on the doors and the gorgeous air vent design have been upgraded successfully.

The three-spoke leather steering wheel in the GLB350 is a highlight - it’s the perfect width and well executed.

Overall the design is modern, tech focussed and very Benz.

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.

The extra length and width means more cabin space which is more apparent in the rear. But there is ample space up front, especially headroom.

The centre console sits up a little too high for my liking but it means you have under console storage with two USB-C ports, and a rubber mat so your phone doesn’t slide around.

It’s got a really deep central bin, while door cavities will only hold smaller bottles. You also get a wireless charger and two cupholders.

There is only a handful of buttons - hazard lights, volume, voice command and drive mode selection - under the central air vents. All other functions are found in the multimedia screen.

Benz has been a standout in the past decade with its MBUX multimedia system and the latest version is responsive, relatively easy to navigate (once you’ve located the key controls), and the graphics look super sharp and cool. The digital instrument cluster is similarly excellent.

Hopping into the second row, the seat base is set higher than the front seats for stadium seating. The seats have some bolstering but quite a lot of lumbar support.

There’s ample space in the second row, thanks to 68mm more space from the back of the seat to the front seat and an extra 34mm of headroom compared to the old car. I have ample knee, head and legroom behind my 183cm (six-foot) tall driving position, although my head is about the same height as the top of the window frame which impedes a little.

Amenities include smallish map pockets, two USB-C ports and knee-level air vents, which is always good to see. There’s a deep but skinny bottle holder on either side and a fold-down centre armrest that sits up a bit too high but it’s wide and has two shallow cupholders and a neat little phone holder.

Each of the 40/20/40 split seats folds via a pull strap at the seat base and the good news is you can adjust the second row backrest a little. The base is also on rails so it can slide fore and aft.

That is how you lower the seats to get into the third row, which is strictly for children. Benz has made it slightly easier for littlies to get back there but it is not a space for taller humans. In fact, Benz recommends up to 171cm tall at most.

One gripe is that there is no sunshade or blind for the massive standard panoramic fixed glass roof. Benz says it is tinted and has a film to reduce UV light and heat, but I’d say a few hours driving in Australian summer will challenge that. Benz isn’t the only brand doing this, but at least you can buy an accessory blind for your Polestar or Tesla. The fact is, not everyone wants a glass roof, especially in Australia, so this feature should be an option.

The boot can swallow 145 litres with all three rows up, increasing to 480L with the third row stowed and 1605L will all seats lowered. This is all decent for a smallish seven seater but if boot space is a priority then maybe have a look at a GLC.

There’s a floor mat and cargo blind but sadly no spare wheel of any kind, just a tyre repair kit, which isn’t great.

The 2026 GLB line-up includes two mild-hybrid and two EV model grades, for now. We can probably expect a spicier AMG version down the track.

Things kick off with the GLB200 front-wheel drive mild-hybrid at $65,400, before on-road costs. This is $2200 cheaper than the previous 200.

Next up is the GLB220 4Matic, which is Benz speak for all-wheel drive. That costs $76,100.

The most affordable EV is the rear-wheel drive GLB250+ at $74,990 which is about $10,000 more than the base hybrid. It’s also about $14,000 more affordable than the previous equivalent EQB grade. Clearly Mercedes has seen the shift in the market and adjusted its prices accordingly.

The range tops out with the GLB350 4Matic at $86,200.

It’s tricky to compare the GLB to other mid-size SUVs as it occupies a fairly rare space given its boxy shape, two powertrain options and seven-seat layout.

A base BMW X3 mild-hybrid is $20,000 pricier than the entry GLB, while Volvo’s EX60 EV will start from $87,000. But they only have five seats each.

Interestingly, a Tesla Model Y L with six seats is $74,900 - just $90 cheaper than the GLB250+. You could argue, however, that Tesla is not a premium brand.

Standard gear in the GLB200 includes:

• Keyless entry and start
• 10.25-inch driver instrument display
• 14-inch central multimedia touchscreen
• Google Maps
• Digital radio
• Heated and power-adjustable front seats
• 360-degree camera
• Head-up display
• Black synthetic leather
• Ambient lighting
• Heated front seats
• Privacy glass from the B-pillar back
• Power tailgate
• Panoramic fixed glass roof
• Automatic climate control
• 19-inch alloy wheels

Step up to the GLB220 4Matic and you’ll also get:

• A ‘transparent’ bonnet
• Terrain mode
• Nappa leather sports steering wheel
• Suspension with adjustable damping
• AMG Line and Night Package styling
• 20-inch AMG multi-spoke alloy wheels

The GLB250+ EV comes with everything you get in the two mild-hybrid grades but also gets a seven-metre home/public charging cable.

The flagship GLB350 4Matic gains the Terrain mode and transparent bonnet of the other 4Matic grade, as well as a second motor and a bump in power and torque.

The tech offering is very impressive and makes up the majority of the standard features list. It’s an extensive list and there’s a lot more when it comes to safety features (see the Safety section). Thankfully Benz no longer offers stripped-out, bare-bones base grades. You could even suggest the GLB offers decent value-for-money. Who would’ve thought?

Being a Benz there are a few options packs including AMG Line for the base grade and a $4000 Premium Plus Package with Digital extras.

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.

Both mild-hybrid versions of the GLB are powered by a 1.5-litre four-cylinder turbo-petrol engine with 48-volt mild-hybrid tech that includes a 1.3kWh lithium ion battery.

The front-wheel-drive GLB200 delivers 120 kilowatts of power and 250 Newton metres of torque for an 8.7-second 0-100km/h dash time.

The all-wheel drive GLB220 4Matic gets a power and torque boost to 140kW/300Nm for a 7.5-second 0-100km/h time. Both petrol grades use an eight-speed dual-clutch automatic transmission.

For the EVs, the rear-drive GLB250+ delivers 200kW/335Nm and hits 100km/h from zero in 7.4 seconds.

The GLB350 4Matic ups that to 260kW/515Nm and a 100km/h dash time of 5.5 seconds.

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.

The GLB EVs uses a nickel manganese cobalt (NMC) battery with 85kW of usable energy.

Driving range and energy efficiency for the GLB250+ is a decent 570km and 15.5 kilowatt hours per 100km. The two-motor AWD GLB350 range drops slightly to 554km and uses 17.7kWh/100km

The EVs have four regenerative braking modes. After a long morning drive in the GLB350 I recorded 15.5kWh, which is solid.

The new GLB uses an 800-volt architecture supporting DC fast charging up to 320kW. Under the right conditions at a high-powered DC charging station, you can technically add up to 260km of range in 10 minutes, according to Mercedes.

AC charging capacity is available up to 22kW and there are four regenerative braking modes, as well.

When it comes to fuel economy in the mild hybrids, the GLB200 consumes 6.1 litres per 100km and the GLB220 sips 6.5L. This powertrain has the ability to use electric power to coast when cruising at highway speeds.

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. 

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. 

I have driven the previous GLB250, which was a fun, punchy SUV. There’s no sporty second-gen variant yet, but if you’re after performance, check out the EV rather than the mild-hybrid.

I only drove the mild-hybrid briefly at the launch event so I’ll focus most of my impressions on the EV. The GLB220 4Matic is quick enough off the line, but there is some lag. Brakes are strong and the cabin is well insulted.

But for me, the EV is the clear pick.

Of the EVs I only drove the GLB350 4Matic as Benz didn’t have a 250+ available.

It’s very quick from a standing start, but not whiplash quick and that is perfectly appropriate for a family-friendly SUV. It delivers the power in a linear manner but when you put the foot down it is very responsive.

I couldn’t detect a massive difference between Comfort and Sport mode to be honest, but you get enough punch in Comfort.

The GLB is tall and top heavy so there is body roll but that’s fine for this sort of vehicle. You’ll notice the weight of this car if you push it into a tight bend at speed - it’s quite heavy and I felt a bit of lateral movement, but the traction control systems help keep the car in check. The grippy tyres help here, too.

Benz has worked hard to improve ride quality with the new-gen model and it shows. The drive route from Melbourne’s south-eastern suburbs to the Mornington Peninsula was littered with potholes, some that looked like they could cause serious damage. The GLB soaked up even some of the sharper holes like a pro. The ride at urban speeds is calm and measured.

The sound deadening measures have clearly helped as well as it is a much quieter cabin than its predecessor. All of this adds to the feeling that this GLB is a more refined, premium SUV than the old model.

I found the steering a little light and twitchy at the start of the drive but by the end of the day I noticed some heft to the feel, and it’s still direct.

The brakes in the EV are a little slower to respond than the mild-hybrid, which takes some time to get used to.

But overall, the drive experience is largely very positive.

The 2026 GLB is yet to be tested by Euro NCAP or ANCAP, but Benz says it should happen next year.

Benz has packed the GLB with standard safety gear from the base grade, including:

• Auto emergency braking
• Adaptive cruise control
• Blind spot assist
• Lane keeping aid
• Speed limit warning
• Brake assist
• Exit warning
• Emergency stop function
• Evasive steering function
• 360-degree camera
• Automatic parking

It also comes with Mercedes’ Pre Safe system that uses sensors to help protect occupants by preparing the cabin milliseconds before an unavoidable crash or rollover. It will tighten the seatbelts, shut any open windows or the sunroof, tighten seat bolsters, move seats to a safer position, and even emit a sound to prepare your ears all in a bid to protect occupants.

The 2026 GLB comes with eight airbags, including curtain airbags that stretch all the way back to cover the third seating row and a front centre bag.

The active driver assist systems (ADAS) are incredibly well calibrated and unobtrusive. No incessant beeping here. In fact I didn’t get beeped once on the launch drive. The most noticeable ADAS warning was a vibration in the steering wheel when I drove close to the lane marking, but it’s subtle.

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.

The GLB comes with Mercedes’ five-year, unlimited kilometre warranty, which is now the standard in the premium segment. The EV’s battery warranty lasts eight years or 160,000km, which is also pretty standard.

Services are required every year or 25,000km which is a decent interval.

Benz offers pre-paid service packages running for three, four or five years. The mild-hybrid is $3430 for three years, $4680 for four and $6300 for five years.

The EV is more affordable to service, costing $2525 for three, $3765 for four and $4440 for five years.

This is quite pricey compared to rivals. BMW’s iX3 is offered with a six-year pre-paid plan and it’s $2420. The Polestar 4 is free to service for the first five years.
