Audi E-Tron vs Mercedes-Benz GLB-Class

What's the difference?

The e-tron S looks mean, feels premium, and blends serious power with surprising grace under pressure. I still can’t shake the feeling I had with the standard e-tron, though, that this car is an Audi sports SUV first and an electric car second, and its weight holds it back from being as fun to drive as I think some rivals are.

If you love Audi and you want to go electric without stepping into something too unfamiliar it’s a great option. If you want an electric car which takes full advantage of what the next generation of technology can offer, keep an eye out, there’s plenty of fresh metal on the way.

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.

The e-tron S looks properly mean, with its adjustable ride-height suspension and enormous wheels combining nicely with the extra subtle sporty highlights to make for a squat SUV which clearly means business.

The width is especially evident with those accentuated wheelarches and the lines set by the lower wing to draw your eyes out to its edges. In profile it's easy to see its long wheelbase and tapered rear roofline, giving even the SUV a slinkier frame than you may be used to when looking at the comparatively boxy Q5.

The thing that strikes me about Audi’s e-tron range, though, is how little a departure it is. It ambiguously slots somewhere above the Q5 and below the Q7, but sticks very closely to the German brand’s styling script.

Sure, it looks a bit lower to the ground, and a bit meaner than you might expect for an EV, but it’s not as much of a departure as Jaguar’s I-Pace or BMW’s iX.

I suppose the biggest advantage here is nobody is going to say the e-tron’s overall visage is controversial, and certainly, it will appeal to existing fans of Audi’s design.

Inside it follows much the same theme, with all the key touchpoints and styling elements nearly identical to other Audis in the range, if not very similar.

It feels like a sensible, refined place in the cabin, with the only whacky pieces being the extra touchscreen for the climate unit and the strange thumb-operated shifter mounted on a floating piece which looks and feels like it could be the throttle control for a jet engine.

The dash is a bit more integrated and modern than in the conservative Q5 or Q7, with the air vents leading to the digital instrument cluster as part of an aesthetic three-terrace design which runs across the entire dash and into the doors.

The screens which appear in place of wing mirrors take a bit of getting used to. Aside from those notable departures, the interior continues the theme of sticking closely to the Audi formula, providing a more modern space which will still be familiar to existing fans of the brand.

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.

As an electric vehicle, the e-tron has certain advantages over its combustion equivalents, and overall makes for an accomplished family-sized SUV. But there are areas where more could be done to take advantage of its high-voltage features and abundant footprint.

Up front in the cabin is a good place, with both occupants treated to lavish seats with plenty of head and legroom, great adjustability, and plenty of width in the cabin.

The finishes are beyond premium with thick chunks of well-padded leather meeting your elbows, hands, and knees at every point. As always the lovely Audi switchgear exists in most places, but the removal of solid toggles and buttons in favour of an extra touch panel feels unnecessary.

There’s still a physical volume knob, and while the climate touchscreen is plenty large enough to have a shortcut button for every function without needing a sub-menu, it feels like you have to move your eyes too far from the road to know you’re going to jab it in the right spot.

Even the main touch panel has an interesting haptic feedback effect for each press, designed to mimic the solidly-sprung button hardware the brand has used in the past.

The screen looks amazing and is fast and sharp, key hallmarks of computer hardware that's up to the task, although the resolution is so high the touch elements when using Apple CarPlay end up being a little small and hard to stab at while you’re trying to keep your eyes on the road.

For storage there’s a big bottle holder and bin in the doors, a large cutaway with a storage tray, dual bottle holders, and power outlets in the centre, with a further smallish storage area under the armrest console.

Unlike some EVs there’s no huge cutaway under what was traditionally considered the transmission tunnel, although there is a small bay with the USB-C ports.

The rear seat feels good for space, with an almost flat floor and decent legroom and width, although headroom could be better.

There are netted pockets on the backs of the front seats and decently-sized bottle holders in the doors, with a further set in the drop-down armrest.

The quad-zone climate with its own touch panel and adjustable centre vents is a nice touch in the rear, as is the set of USB-C ports below. The hard backings to the front seats and built-in sun blinds our car had will even be great for kids.

The boot measures in at 660 litres, which is high for the segment. It fit our three-piece CarsGuide demo luggage set with room to spare, and that's despite the massive battery pack under the floor.

There’s auxiliary storage, too, with a further bay under the boot floor and a second small tray situated under the bonnet, both useful for keeping your charging paraphernalia.

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 S-branded e-tron sets itself apart from the rest of the range with a seriously powerful set of three motors. There are two on the rear axle, and one on the front axle.

The total combined output of this collection is 370kW/973Nm, which for a combustion car, would be unprecedented.

To be fair, these figures are under a ‘boost’ mode, with the car generating a still strong 300kW/800Nm in most situations.

The three motor drivetrain allows for an electric version of Audi’s ‘quattro’ all-wheel drive system which the brand says can react to changes in 30 milliseconds and move torque appropriately.

The system is rear-biased, and in the name of efficiency the front motor is only used when required under acceleration or cornering.

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.

The e-tron may be electric, but it’s also a performance car. To that end, its energy consumption, relative to the field, is behind the pace.

In fact, at a whopping 27.8kWh/100km, driving the e-tron around feels like the electric equivalent of steering a big V8.

It produced one of the highest consumption numbers I have seen from any EV during my time with it. Considering this number is even below the WLTP consumption number, which is 28.4kWh/100km, that's not great.

For comparison, the Mercedes-Benz EQC's official number is just 20.8kWh/100km, while the Jaguar I-Pace consumes 21.2kWh/100km according to the WLTP procedure.

Yes, they aren’t performance cars in the same sense, but it’s still a big difference.

I made sure to take it out and stretch the e-tron’s legs to assess its performance in its more sporty driving modes, but the majority of my time with the car was spent in a more comfort-oriented setting and with the regenerative braking set to maximum.

Possibly as a result of its real-world consumption, my car was showing about 350km of range on a full charge, a little below the official WLTP number of 364km, although it is worth noting the enormous 21-inch alloys do their part to reduce the range. The car ships with 20-inch wheels in Europe.

The good news is the e-tron is capable of charging fast, with its max DC charging speed set at 150kW (allowing for a 5.0-80 per cent charge time for its 95kWh battery of 30 minutes), and its AC charging speed set at 11kW, which allows a slow-charging time of around seven hours.

If you intend to park on the street or live in a unit where installing charge infrastructure is impossible, I would strongly recommend you consider the 22kW AC charging upgrade which will cut the AC charge time in half.

While there are few public stations currently capable of the full 22kW in Australia, it will future-proof your car for ideal convenience charging for when they're more commonplace. 

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.

Does the e-tron live up to the promise set by sporty Audis which have come before it? The answer is interesting.

There is no doubt the e-tron S is rapid, at times absurdly so. If you stick it in the required S mode and hunker the suspension down, planting the accelerator makes its claimed 0-100km/h sprint time of 4.5 seconds suddenly very real.

It lurches ahead without so much as a squeak from its enormous tyres, grabbing the road with its front axle as it warps you forward.

So yes, this electric performance car is no doubt quick. It is also heavy. Weighing in at a tare mass of 2830kg, the e-tron S is quite literally massive.

The trouble is, while its powerful electric motors are great at overcoming this gravitational obstacle in a straight line, it’s in the corners and at low speeds where you feel every bit of it.

The e-tron crashes over larger bumps, it’s suspension struggling to deal with the combination of its weight and low-profile tyres, while it can also feel cumbersome in the corners around town.

The suspension is better at levelling things out once you gain a bit of pace, and the tyres work with the all-wheel drive system to put in a Herculean effort when carving up bends at speed, but there’s the ever-present lurch of weight always working against you.

This feeling isn’t helped by the steering tune, which even in its most comfort-oriented setting feels hefty and slow to turn. In the default sport mode, ‘dynamic’, it takes effort to push this car around corners.

Despite the unsettling feeling of it, though, the car holds on for dear life, and I never once felt as though the tyres were remotely in danger of breaking traction when put under pressure.

Is it a performer, then? Absolutely, there’s something mind bending about a vehicle so heavy going so quickly.

Does it feel fun to drive? Less so. I enjoyed the connectivity of the Porsche Taycan offers at speed more than I enjoyed the e-tron S, and its weight and girth demand a nice wide piece of tarmac for you to really wring it.

It’s far from a darty and engaging car like the Q5 can be despite its mammoth power outputs.

Elsewhere, the drive experience feels very Audi, though. The touchpoints and feedback are mostly familiar, as are the software and ergonomics.

The virtual wing mirrors are more of an inconvenience than anything else. This car is already hard to see out of, with big C-pillars and a tall belt line, and the digital exterior mirrors offer what feels like a limited angle of vision and make it extra hard to see out at night.

Some things fall to the wayside a little. The e-tron’s drive system almost hides the regenerative braking setting several menus deep, which, once activated, allows you to set it using the paddle-shifters on the wheel.

Audi says the regen will account for nearly 30 per cent of the car’s range, which is odd because even at the highest setting it feels a bit mild, relying on the user to manually operate the brake for a ‘blended braking’ mode to make up the difference.

It’s a bit of a stretch from the single-pedal driving modes offered on some rival cars.

My theory here, as with this car’s look and feel, is the e-tron is primarily designed to be familiar to an existing Audi customer, or someone coming out of a purely combustion premium rival.

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 has followed its Volkswagen parent in upgrading its warranty to five years and unlimited kilometres, finally leaving BMW and its three-year warranty behind.

The e-tron’s high-voltage battery components are covered by a separate eight-year and 160,000km warranty, but the big win, especially in this premium segment, is the first six years of servicing (covering three 24 monthly or 30,000km visits) is free.

Oh, and your public charging is largely free for the same period too, as Audi throws in a six-year ChargeFox subscription.

Six years pretty much cost-free? Audi, how far you’ve come.

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.
