Audi Q6 vs Mercedes-Benz GLB-Class

What's the difference?

The Q6 e-tron knocks the luxury SUV formula out of the park, regardless of the fact it’s an electric vehicle. It has a slick, sporty feel, a high level of standard equipment for a premium car and at least on paper it’s a solid EV with plenty of driving range.

But here’s the thing: To me, the Q6 e-tron feels exactly how you would expect it to. It’s the same Audi formula, just upgraded for the electric age and in an era where rivals both old and new are using this once-in-a generation opportunity to truly innovate, there’s something a little disappointing about that.

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.

At a distance, the Q6 sticks to the same Audi formula. An inoffensive overall shape with the same core design cues as something like a Q5 are all part of the plan according to the brand, as it attempts to make the idea of switching to electric as easy as possible for its loyal buyers.

Things like the inverted grille (where there’s body colour where black would normally be) framed by a sporty black insert in the shape of Audi's usual combustion grille feels more tactfully executed than Mercedes’ attempt to bring an electrified touch to its EQ range.

Up close though, I must admit this car looks a bit meaner than your average Q-series SUV. The way the wheels sit wide and bold, accentuated by the inflated wheel arches (or blisters as Audi calls them) give the Q6 a tough feel, sitting boldly on its haunches.

Audi fans will love the exterior design, and it may convert some to electric car buyers, but it’s hard to see this car bringing new buyers into the fold, especially with more radical designs out there to catch the eyeballs of aspirational EV buyers.

Inside, Audi has traded away the somewhat ageing feeling of the outgoing Q5 for something much more tech-y in the Q6. The dash is dominated by the three large screens, which are also sharp, fast and responsive, with improved software this time around.

It is a lot though. While the exterior design plays it safe and the interior avoids the kind of obnoxiousness of an overbearing portrait-oriented screen, it feels almost unnecessary for every grade to get the three-screen layout.

Elsewhere the textures and patterns feel the part, and there’s no shortage of attention to detail when it comes to soft trims down the centre console, or clever new air vent fittings, for example.

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.

This brings us nicely across to practicality, because along with the enormous set of screens, the Q6 brings with it a significant reduction in the amount of switchgear available. The centre console still features a physical volume dial, and there are a handful of shortcut buttons, but the climate functions are exclusively controlled via touchscreen menus. 

Additionally, the Q6 features an array of haptic buttons on the steering wheel (which some will remember, were much maligned on Volkswagen products) alongside a huge haptic panel on the driver's side door controlling everything from the headlights to the windows and mirrors.

It feels as though Audi has dressed the cabin up with new stuff rather than cost-cutting, which is often the case with its rivals. To Audi's credit, these functions are well enough laid out they didn’t bring much frustration on our test drive. Mercifully the screens are fast so adjusting functions is instantaneous, but these features are never as easy to use as physical buttons when you’re trying to concentrate on the road.

No matter how well they work, not everyone will love them (especially rusted-on Audi buyers who will be used to a decent array of physical switches).

There’s plenty of storage in the cabin. The doors feature a big pocket and bottle holder, with a further two bottle holders in the centre with adjustable ridges and a gloss roller cover to keep things tidy when you’re not using them.

Up front there’s a large storage bay with the phone charger mounted vertically on its side to minimise the amount of space it uses. The centre console box is shallow but extends quite far under the console owing to the car’s electric platform, and the array of charging ports are easy enough to reach.

As usual with Audis, the front seats are bolstered nicely and there’s no shortage of adjustment on offer to find a comfortable seating position.

The back seat is spacious enough, although I was expecting more for a car on a new EV platform designed to be larger than the already-spacious Q5. At 182cm tall I have decent, but not a massive amount of room behind my own driving position, with airspace for both my knees and my head. As a saving grace here, the floor is more or less flat and the car is quite wide so the centre position will still be useful for a full-sized adult.

Storage comes via bottle holders and pockets in each door and nettings (which I don’t love as they tend to age poorly) on the backs of the front seats. Unlike the Q5 the rear row is fixed instead of on rails, but it does feature individually folding seat backs, which means you can drop the centre position to put long objects in the cabin and still have two rear passengers (kind of like a ski port, but better).

The boot measures 526 litres (or 1529L with the rear seats down) which seems about right, although we didn’t have a chance to test it with our usual luggage set. It has some space under the floor for the storage of cables, although like many EVs it doesn’t have a spare wheel, only an inflator kit. It also has a frunk, which measures 64 litres. These spaces might seem like a bit of a gimmick but the Q6 comes with a clever little fitted duffle bag which slots perfectly into the void where you can keep both your wall socket and Type 2 to Type 2 charging gear.

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.
 

Priced from $88,535 plus on-road costs, the GLC35 currently sits atop the GLB range, above both the $59,900 GLB200 and $73,535 GLB250.

Standard equipment not already mentioned in the GLB35 includes dusk-sensing lights, rain-sensing wipers, power-folding side mirrors, black roof rails, rear privacy glass and a power-operated tailgate.

Inside, satellite navigation with live traffic, Apple CarPlay and Android Auto support, digital radio, a 225W sound system with nine speakers, keyless entry and start, power-adjustable front comfort sports seats with heating and memory functionality, auto-dimming mirrors, illuminated ‘AMG’ scuff plates and ‘AMG’ floor mats feature.

As is commonplace for Mercedes-Benz models, the GLB35 has plenty of options with most expensive, so you could drive away with a vehicle that’s dearer than you originally thought.

But aside from a spare wheel and some safety equipment we’ll cover in a moment, the GLB35 doesn’t leave much to be desired, which is always a good thing.

Nonetheless, our test vehicle was finished in $1490 Iridium Silver Metallic paintwork, which is one of eight extra-cost exterior colour options.

As mentioned, the GLB250 is a unique proposition, so it’s only comparable rival, the more affordable but less sporty Land Rover Discovery Sport P250 HSE ($78,432).

A lot of the bigger innovations for the Q6 e-tron can’t be as easily seen because they’re primarily a result of its new platform. This Premium Platform Electric (PPE) architecture is new to Volkswagen Group and is designed specifically by and for Audi and Porsche rather than the MEB platform which underpins both the Q4 e-tron from Audi and ID.4 from Volkswagen.

Benefits include a primarily rear-drive orientation, the ability to accommodate more sophisticated suspension layouts, software capable of reaching deeper into the car (when it comes to updates), and of course a new electrical architecture with the capability to support 800-volt systems.

Power is impressive across the range. The base Performance puts out 225kW/485Nm from its rear motor, and can sprint from 0-100km/h in 6.6 seconds. The Quattro adds a second motor on the front axle, which combines with the rear motor for totals of 285kW/580Nm. It can sprint from 0-100km/h in 5.9 seconds.

The range-topping SQ6 ups power significantly to 360kW/580Nm from its dual motors, lowering the 0-100km/h sprint time to just 4.3 seconds using launch control.

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.

Driving range is excellent no matter which variant you pick. You’d hope so given the size of this car’s nickel-manganese cobalt battery pack. The usable 94.9kWh capacity grants the Performance 558km of range, the Quattro 542km of range, and the SQ6 568km of range, all measured to the WLTP standard.

The 800-volt architecture which forms part of the new PPE platform unlocks ultra-fast DC charging times, which are impressive given the size of the Q6 e-tron’s battery pack.

A claimed peak charging speed of 270kW will take the battery from 10 to 80 per cent in just 21 minutes if you can find a fast enough charger. Audi says the charging system is optimised to maintain its peak charging for as long as possible (something we’ll have the opportunity to test at a later date, although we’ve found these claims to ring reasonably true for the e-tron GT on the older J1 platform).

On a slower AC charger (the kind you might find at the local shops), the maximum charging speed is an acceptable 11kW, although the max rate of 22kW would be nice to see. At 11kW to charge from 10 to 100 per cent will take around eight hours. In an unusual touch, the Q6 gets a second AC charging port on the driver’s side to go with the AC/DC combo port on the passenger side.

Sadly, there’s no vehicle-to-load or vehicle-to-grid features for the Q6 e-tron range, particularly given the size of its battery pack. While you might not use these features initially, it would be good to have them long-term as more use-cases become apparent.

When it comes to energy efficiency the Q6 e-tron’s official numbers are 19kWh/100km for the Performance, 19.5kWh/100km for the Quattro, or 18.4kWh/100km for the SQ6. Interestingly, the SQ6 has the most impressive efficiency rating, which, according to Audi is due to the lower ride height and better aerodynamic performance afforded by the air suspension.

The consumption numbers are about on-par for a vehicle this size, but are far from impressive numbers I’ve seen in the real world on similarly sized rivals like the Ford Mustang Mach-E for example. As we were jumping in and out of vehicles on this launch, expect a more thorough real-world efficiency evaluation at a later date.

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.

Here’s the thing, Audi has talked a big game about this new PPE platform, but from behind the wheel the Q6 e-tron doesn’t offer the kind of massive step change I was expecting. In fact, just one look at the car and I felt like I knew how it would drive, and it didn’t stray from this expectation.

The Q6 e-tron is defined by its balanced weight distribution, its sharp steering and the powerful follow-through its electric motor provides. It defies its weight in the corners, but at the same time its SUV body struggles to shake the sheer mass which remains present under the floor.

As a result, it doesn’t have the reactive athleticism of its combustion counterparts, instead offering a more sturdy feel of the road, bolstered by thick tyres. Still, no matter which variant you pick, you’re getting more power delivered more quickly than entry-level engines in the Q5 range, for example.

There’s something to be said for how exhilarating these can be. These new motors also don’t have the same disappointing hollowed-out acceleration feeling lesser MEB-based cars can have when it comes to overtaking manoeuvres.

And yet, there’s something disappointing about how the Q6 feels to drive. It’s exactly what you’d expect from a powerful Audi EV and nothing more, where some rivals, and even Audi’s own e-tron GT feel more like an absolute generational leap.

There’s more, too. Versions that don’t feature the acoustic glass had a surprising amount of road noise on coarse chip surfaces. I’d expect better for a premium car on a new platform, and the standard suspension had the odd jilted moment as it wrangled with the sheer weight of the Q6.

The air suspension package was a massive improvement on this, damping both noise levels and the undulations and imperfections the road can throw at you. It stood out to me as a very worthwhile option to have, even on base cars if you’re chasing the best handling and ride this platform has to offer.

The SQ6, featuring the lot, is of course an absolute monster of a car, with even more powerful acceleration, and the air suspension as standard, although on the road at least the additional power over the Quattro was hard to quantify. 

We didn’t have the chance to sample the base Performance at the launch. The rear-drive dynamics and lesser weight over the front axle as well as smaller wheel will make for a different feel compared to the Quattro and SQ6 we did drive, so we’re hoping we can bring you a review of this car at a later date.

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.

ANCAP awarded the GLB range its maximum five-star safety rating in 2019.

Advanced driver-assist systems in the GLB35 extend to autonomous emergency braking (AEB) with pedestrian and cyclist detection, lane-keep assist, blind-spot monitoring, rear cross-traffic alert, traffic sign recognition, driver attention alert, tyre pressure monitoring, hill-descent control, hill-start assist, park assist, a reversing camera and front and rear parking sensors.

Is anything missing? Well, steering assist, adaptive cruise control, active blind-spot monitoring and front cross-traffic alert form the optional Driving Assistance Package ($1990), which definitely should be standard at this price point.

And let’s not forget the two other noticeable absentees: surround-view cameras and high-beam assist. They’re annoyingly part of the optional Vision Package ($1190), which was fitted to our test vehicle.

Nonetheless, other standard safety equipment includes nine airbags (dual front, front-side, curtain and rear-side plus driver’s knee), anti-skid brakes (ABS), electronic brake-force distribution (EBD) and the usual electronic stability and traction control systems.

The usual five-year and unlimited-kilometre warranty applies to the Q6 e-tron, alongside six years of roadside assistance and an industry-standard eight-year or 160,000km battery warranty.

Additionally, Audi throws in one year of a Chargefox subscription, theoretically making your first 12 months of fast DC charging free (provided Chargefox administers your local charging infrastructure).

At the time of writing, Audi was yet to provide service pricing, but the interval is nice and long, at 24 months or 30,000km. A pre-paid service package covering six years and 90,000km comes in at just $2080 which is super affordable for a car from a traditional luxury brand, even if it only covers the first three workshop visits.

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.
