Mercedes-Benz GLB-Class vs Audi Q5

What's the difference?

It’s easy to say the GLB35 doesn’t deserve to be called an AMG when looking at its credentials on paper, but get behind the wheel and it’s evident Affalterbach played a key role in making it feel as special to drive as it should be.

The GLB35 has all of the great qualities of the GLB250 and other GLB variants, but successfully adds a performance focus to make for an even more compelling package.

Indeed, the GLB35 proves you can pretty much have it all.

The new Q5 does a lot right even if it doesn’t feel as resolved from behind the wheel as I had expected.

It catapults one of the oldest premium SUV nameplates into this decade, and all three of its launch powertrain options are great, so you can’t really go wrong.

Each features the smoothness and efficiency of genuine hybrids backed by punchy turbo combustion thrills, while the increase in standard kit across the entire range is notable at a very reasonable price increase.

With the boxy and therefore rugged-looking GLB laying some great foundations, it’s no surprise the GLB35 looks pretty damn good – to these eyes, at least.

Being an AMG model, it stands out from the crowd with an aggressive body kit, with the chunky bumpers, aerodynamic roof spoiler and racy rear diffuser all unique alongside the now-signature Panamericana grille insert.

A set of 20-inch alloy wheels with 255/40 tyres ups the ante at the side, where the carryover black plastic wheel-arch and skirt cladding serves as an obligatory reminder that this is an SUV.

Also of note are the nicely designed LED headlights and tail-lights, which literally light the way, but there’s no getting past the bespoke diffuser element, which integrates the sports exhaust system’s dual 90mm tailpipes.

Inside, the GLB35 is a technological tour de force, with a pair of 10.25-inch high-resolution displays proudly sitting side by side atop the dashboard, with one the central touchscreen and the other the digital instrument cluster.

Both are powered by Mercedes-Benz’s MBUX multimedia system, which arguably remains the best there is today thanks its speed and breadth of functionality and input methods.

The GLB35 is also properly premium. Lugano leather upholstery covers the seats and armrests, while Nappa trims the sports steering wheel. Even the door shoulders and inserts get ‘cow hide’, although theirs is of the artificial variety.

Soft-touch materials are used for the upper dashboard, leaving hard plastics to the lower sections, which is what you’d expect for the price.

While the black headliner makes for a dark cabin, brightness comes from the metallic trim used throughout, notably on the steering wheel, dashboard, doors and centre console. And let’s not forget the pop of colour provided by the addictive ambient lighting.

And mercifully, scratch- and fingerprint-hungry gloss-black accents are limited to the surrounds of the turbine-style front air vents, dual-zone climate controls and centre console.

Unique to the GLB35 are Carbon Structure trim and stainless-steel sports pedals, just in case you forgot you weren’t driving a regular GLB.

Proportionally, the new Q5 is quite a departure from its curvaceous predecessors, thanks to a more chiseled bodyline and stronger flares over its wheelarches. While this makes it the biggest stylistic departure for the Q5 ever, embracing its all-new PPC (Premium Platform Combustion) underpinnings, its stylistic motifs are still somehow very familiar.

The traditional Audi grille is maintained, although has been modernised with a geometric pattern and integrated highlight pieces depending on styling package, and even the light profiles manage to be somewhat familiar despite their twinkly new customisable LED elements and contemporary slimline appearance.

A closer look only makes the car feel more contemporary, with strong contours around its face and bumpers, which were absent from its more plain-looking predecessors.

In addition, the brand tells us the Australian market in particular has one of the highest levels of uptake of large wheels, so it offers a range of designs to choose from on the options list, many of which are on the larger side, despite the standard wheel being 19 inches.

The interior is where the biggest changes are. While Audi interiors have been familiar for the longest time, the new Q5’s interior appointments feel dropped directly out of its Q6 e-tron electric alternative.

The result is a completely re-thought approach to the interior design, which is now dominated by huge touchscreens as well as a collection of contemporary shapes and mouldings that transport the Q5 into the current decade.

Still, elements of familiarity are present. The seats feel like Audi seats, the materials are as you’d expect for the brand and the wheel is backed by familiar switchgear.

Measuring 4650mm long (with a 2829mm wheelbase), 1845mm wide and 1660mm tall, the GLB35 is more like the GLC43 in size than the GLA35, making it a mid-size SUV despite its small underpinnings. And that is good news for practicality.

Cargo capacity with the 50/50 split-fold third row stowed is more than solid, at 565 litres (VDA), but it can be increased to a cavernous 1800L with the 40/20/40 split-fold middle bench also not in use. If six or seven passengers are onboard, though, there’s very little room to move.

Nonetheless, the boot is still well packaged, featuring a huge aperture, no load lip, and a flat floor, which make loading and unloading bulkier items a hell of a lot easier. And even the load cover can be stored underfloor when out of action. How good.

There are also four tie-down points, two bag hooks, a side storage net and a 12V power outlet on hand to make matters even easier, while the rear seats can be stowed from the boot.

While we’re on the topic, Mercedes-Benz says the third row can accommodate passengers up to 168cm tall, with the middle bench able to slide fore and aft by up to 140mm.

Yes, I'm too tall, at 184cm, but I can still sit in the very back, although not in total comfort. All in all, about a centimetre of legroom and negligible headroom and toe-room are on offer there for me.

That said, getting in and out in the first place is the real challenge here, with the middle bench unable to tumble forward for easy ingress and egress. Yep, you’re not going to look smooth either way. Children can deal with it, but adults won’t be thrilled.

Therefore, the middle bench is the place to be, even when it’s slid all the way forward. Behind my driving position, it offers about a centimetre of legroom, but this can be increased to several inches by sliding it all the way back.

Either way, plenty of toe-room is available alongside more than an inch of headroom. The latter is more impressive when you consider that’s what you get with the standard dual-pane panoramic sunroof fitted.

Even better, the second row can seat three adults at a pinch, partly thanks to the low transmission tunnel, which means there’s the right amount of space for six fully grown feet across the two footwells. It goes without saying children will again be fine.

Speaking of which, four ISOFIX and five top-tether anchorage points are on hand for fitting up to four child seats across the second and third rows, which makes the GLB35 a serious option for families that like to be sporty.

There are plenty of in-cabin storage options, with the large central storage bin featuring a pair of USB-C ports, while the glovebox is also quite useful, even if it is oddly shaped. And there’s also a sunglasses holder in front of the rearview mirror.

The centre console’s cubby isn’t really designed for storage, with it basically taken up by two cupholders, another USB-C port and a wireless smartphone charger.

The front door bins can accommodate one small and two regular bottles each, which is great, while their rear counterparts can take one small and one regular apiece.

Second-row occupants also have access to a fold-down armrest with another pair of cupholders, but being of the retractable variety, they’re flimsy.

These passengers also have two USB-C ports, with the pair folding out below a small cubby and air vents, which are found at the back of the centre console. Storage nets are also fitted on the front seat backrests.

And don’t worry; the third row gets in on the action, with two cupholders (one regular, the other small) splitting the seats, which have individual USB-C ports and device straps to the sides.
 

While the interior might feel as modern as they come, it also brings with it some of the pitfalls of contemporary design themes.

The most obvious is the over-reliance on touch panels for controls. The most egregious example is the lack of physical buttons for the climate control, which is interacted with via a permanent part of the touchscreen, but it doesn’t end there.

On top of this, there are capacitive gloss finish panels for the steering wheel controls, and even a capacitive panel in the door to control the mirrors and lights. It all looks swish, but isn’t the best to use compared to just… buttons.

Apple CarPlay worked flawlessly in my time with various versions of the car, and the stock software is fast and crisp. Interestingly the digital instrument cluster is the most plain version of Audi’s usually stellar virtual instruments yet. Without the big animated cluster dials it used to have it feels a bit less fun to look at.

Adjustability and space is great for front passengers, as is the amount of visibility on offer, plus the seats are as comfortable as ever in all grades.

Storage is ample in the cabin, with big bottle holders in the centre console, large pockets in each door, and a halfway decent centre console. The phone charger sits tucked away at the front with the USB-C outlets and a volume dial.

The back seat is less impressive. The Q5 never had the most spacious second row in this mid-sized segment, but it’s disappointing to see this new-generation car hardly improves on the formula. It’s spacious enough for me at 182cm tall behind my own driving position, with enough room for my knees and airspace for my head, but it’s certainly not as spacious as many rivals. In addition, the centre position is compromised by a huge rise in the floor, making it a hard pitch for an adult to sit there.

On the plus side, there’s plenty of amenities with bottle holders in each door, a further two in the drop-down armrest, netted pockets on the backs of the front seats, and an entire third rear climate zone with touch panel temperature control and physical air vents. There’s also two USB-C outlets.

One trade-off for the small second row is a large boot. It measures 520 litres with five seats up, or 1473L with the second row down. It also comes with a few neat things like a net and sliding cover.

Unfortunately, while there’s a small amount of underfloor storage, there’s no spare wheel, with Audi only offering a tyre repair kit.

The new Q5 arrives in five variants spread across three powertrain options, and the starting price has copped quite a hike. Audi says that's to account for a steep increase in standard equipment, the inclusion of new hybrid tech and the S-Line styling package across the range.

The new entry-level Q5 is the base front-wheel drive TFSI petrol, which wears a price of $81,000 before on-roads, replacing the previous entry-level Q5 35TDI that started at $73,400.

Included is 19-inch alloys, Matrix LED headlights, LED tail-lights with projection light, an 11.9-inch digital dash and 14.5-inch multimedia touchscreen with wireless Apple CarPlay and Android Auto, online connectivity with built-in navigation, eight-speaker, 18-watt sound system, multicolour ambient lighting, leather interior trim with brushed aluminium inlays, wireless phone charging, a 360-degree parking camera, a power adjust driver’s seat with heated front seats, tri-zone climate control, keyless entry and push-start ignition.

This trim level is also available as a TDI quattro with diesel and all-wheel drive at $87,600. Next up is the TDI quattro Sport from $94,100 which adds 20-inch two-tone alloys, a panoramic opening sunroof with shade, S-line front seats, with the S-Line interior package that also features a three-spoke alternate steering wheel design, steel sports pedals and black headlining.

Next is the SQ5 Edition One. The most prominent upgrade for this grade is the return of the 3.0-litre turbo-petrol six-cylinder engine, although this grade also gets its own trim level including 20-inch black metallic alloys, to go with a black pack exterior, red brake callipers, S Sport suspension and privacy glass.

Finally the top-spec SQ5 scores 21-inch alloys, aluminium exterior highlights, acoustic glass, premium leather interior trim, front seat ventilation and message functions, a head-up display, 16-speaker Bang & Olufsen premium audio and improved outputs for the USB-C connectors. Premium paint options are free (aside from Gold) on the SQ5.

Other option packs include the Premium Package ($5400) which adds the head-up display, Bang & Olufsen sound, improved USB outputs and acoustic glazing, the Tech Pro Package ($5700) which is only available on the TDI quattro Sport and SQ5 adding heated steering, a front passenger display, electrical adjust for the steering column, heated rear outer seats and digital OLED tail-lights.

Finally two Style Packs exist, adding 20-inch wheels, a black pack, and privacy glass to lower grades ($4900 for the TFSI and TDI, $3400 on the TDI Sport) with the Carbon Style Package only available on the Edition One and SQ5 for $9200, adding carbon mirror claddings, inlays and a roof spoiler.

On the value front the Q5 is more affordable than an entry-level BMW X3 (20 xDrive - $86,800) and Mercedes-Benz GLC (200 4MATIC - $89,000) although both rivals offer all-wheel drive as standard, rather than the front-wheel drive Q5. Outside of the Germans, the Lexus NX (250 FWD) starts at $63,400, while the Genesis GV70 (2.5T Advanced AWD) starts at $78,700.

With that price tag, I’d say the Q5 is priced just-right compared to its rivals.

The GLB35 is powered by an uprated version of the GLB250’s 2.0-litre turbo-petrol four-cylinder petrol engine, with the AMG-fettled version producing a more substantial 225kW of power from 5800-6100rpm and 400Nm of torque from 3000-4000rpm (up from 165kW/350Nm).

This version is also matched to an eight-speed dual-clutch automatic transmission as well as Mercedes-AMG’s front-biased but fully variable 4Matic all-wheel-drive system.

Thanks to this combination, the GLB35 can sprint from 0-100km/h in just 5.2 seconds with launch control enabled, while its electronically limited top speed is 250km/h.

Here’s where things get interesting. Despite featuring three carryover engine options, the Q5’s big upgrade is the introduction of a hybrid system.

The brand calls this technology MHEV+, which I think is underselling what the system can actually do. Normally a mild hybrid (MHEV) system consists of higher-voltage electrics to assist auxiliary systems and take a small amount of load off the engine, or provide a more robust stop/start system, but this new Audi tech consists of an 18kW/230Nm electric motor placed after the seven-speed transmission that can motivate the entire vehicle under electric power for small periods. It can recapture up to 25kW of energy and is supported by a 1.7kWh battery pack.

The three engine options supported by this include the base TFSI 2.0-litre four-cylinder turbo front-wheel drive (150kW/340Nm), the mid-spec TDI 2.0-litre four-cylinder turbo diesel (150kW/400Nm) exclusively in all-wheel drive, or the SQ5’s 3.0-litre turbo-petrol V6 (270kW/550Nm).

There’s no disappointments here. All powertrains feel up to the task, and for those of you waiting for an all-wheel drive base petrol or a plug-in hybrid, the brand assures us both are on the way soon.

The GLB35’s fuel consumption on the combined-cycle test (ADR 81/02) is 8.3L per 100km, while its carbon dioxide emissions are 186 grams per km. All things considered, both claims are pretty decent.

In our real-world testing, though, we averaged a high 14.1L/100km over 75km of driving split between highways and country roads, so not your typical mix, then. A heavy right foot also played into that result, so expect a better return after a regular run.

For reference, the GLB35’s 60L fuel tank can be filled up with 98RON petrol at minimum.

All engine options are also relatively efficient, although the total fuel reduction from the introduction of this new MHEV+ hybrid technology is surprisingly small. Audi says it saves up to 0.74L/100km and 17g/100km of C02, which doesn’t sound like a lot for a system that can pull the whole car.

Regardless, fuel consumption is 5.7L/100km for the TFSI 2.0L FWD petrol, 5.4L/100km for the TDI 2.0L AWD diesel, or 7.6L/100km for the 3.0-litre petrol V6 SQ5. The emissions are also relatively low for a premium SUV.

Don’t let the GLB35’s family friendliness fool you, this is an SUV that can get up and go.

The engine’s extra power and torque over the GLB250 are immediately felt behind the wheel, with the GLB35 accelerating with the vigour of an all-wheel-drive hot hatch, which makes sense given their similar claims.

And if you have one of the sportier drive modes engaged, the booming noise generated is also special – even if a lot of it is of the artificial variety, pumped into the cabin to make occupants feel like things are getting serious.

What is genuine, though, is the well-rounded transmission, which is characteristically quick with its upshifts. At the same time, it’s also relatively smooth, even at low speed, which has proven to be a challenge for dual-clutch units over time, but not here.

To earn the AMG badge, the GLB35 goes even further with other mechanical upgrades, including sports tunes for the suspension and steering.

Specifically, the GLB35’s independent suspension set-up not only consists of MacPherson-strut front and trailing-link rear axles with adaptive dampers, but also introduces new steering knuckles, transverse control arms on the front axle, and a stiffened subframe.

The resulting ride is actually quite good. Yes, the extra firmness over the GLB250 is noticeable – particularly in the sportier drive modes that stiffen the adaptive dampers all the way – but it’s by no means a deal-breaker.

That said, it’s worth noting our test vehicle was fitted with the optional 21-inch alloy wheels ($1990), so the GLB35’s like to ride even better on its standard package.

This is remarkable considering the handling improvements made, with the GLB35 managing body roll and pitch better than the GLB250 when pushing hard into and around corners, coming out of which grip is plentiful thanks to the all-wheel-drive system.

Thankfully, the standard-fit high-performance braking package consisting of 350mm front and 330mm rear discs with four- and one-piston callipers respectively helped it wash speed away with ease when attacking the twisty stuff with intent, even with 1857kg (kerb) to deal with.

Also on hand is electric power steering, which is speed-sensitive and has a variable ratio in the GLB35. Basically, it’s quicker when you want it to be, remaining on the lighter side in hand until you engage one of the sportier drive modes and weight is increased markedly.

To drive the Q5 is familiar in some ways and less familiar in others. The initial impression is good, with each variant being relatively quiet on the road, offering a nice adjustability and driving position, with great visibility around the car.

The new powertrain options are all a joy to pilot, with all feeling punchy and smooth-shifting through the seven-speed auto. This smoothness is helped along by the introduction of the new MHEV+ tech, which can push the car along at reasonable speeds without needing the engine to assist.

It might not be quite as punchy as some other hybrid systems in terms of overall assist, but it’s certainly better than other systems we’ve seen on the market that barely help with driving or smoothness, and end up being a cynical emissions-saving device. It’s nice to see this tech is a step forward for the brand.

The familiar Q5 driving points are mostly intact, too, with the most notable upgrade being the ride comfort. This car is much more adept at dealing with road imperfections than its predecessor, with a softer suspension response.

This having been said, I expected more from this ground-up new platform. Each version of this Q5 I sampled felt less dynamically engaging than its predecessor. The usually sharp Audi steering tune feels a bit disconnected in this new car, with a little bit too much electrical and software assist, and the suspension, while more comfortable, isn’t as engaging in the corners.

It, too, lends the car a disconnected feeling over undulations and corrugations, giving the new Q5 an overall less resolved feeling from behind the wheel than I would have liked. The previous car was a bit sharp, but at least it was consistent in the way it responded to the road.

The previous car started to feel old towards the end of its run. Previous Audi owners will enjoy how this new car catapults the nameplate into this decade in terms of its cabin ambiance and general demeanour, it would have just been nice to see the consistency return, too.

A massive list of active safety kit is present in the new Q5, from autobahn-speed auto emergency braking (AEB) to lane departure control as well as the expected blind spot and cross traffic alert features (front and rear).

It also features the newer features, like traffic sign recognition and 360-degree cameras, while the brand’s signature high-end adaptive Matrix headlights are standard across the range.

The systems are well calibrated judging by our brief drive, with only the occasional tug of lane keep assist present. In addition, the adaptive cruise is well behaved.

The Q5 is yet to secure an ANCAP score at the time of writing, but it already has a maximum five stars from Euro NCAP in its home market, which I’m sure the brand is hoping will carry across.

As with all Mercedes-AMG models, the GLB35 comes with a five-year/unlimited-kilometre warranty, which currently sets the standard for the premium market. It also comes with five years of roadside assistance.

The GLB35’s service intervals are long, at every 12 months or 25,000km (whichever comes first). Better yet, it’s available with a three-year/75,000km capped-price servicing plan, but it costs $2750, with the third visit alone incurring a $1300 charge.

Audi continues to offer its fairly standard five-year and unlimited kilometre warranty with five years of roadside assist and this is paired with the option of a five-year service plan.

This costs an additional $3520 ($704 per year) for the 2.0-litre variants, or $3560 ($712 per year) for the 3.0-litre V6-powered SQ5. Servicing is required every 1500km or 12 months.
