Audi Q8 E-Tron vs Mercedes-Benz GLE-Class

What's the difference?

The Audi Q8 e-tron ushers in welcome improvements to an already likeable and capable large luxury SUV.

But it is also feeling dated compared to newer and fresher rivals like the BMW iX, isn’t as good to drive as the best, offers disappointing range for the size of the new battery, and prices are creeping up for what is essentially a half-decade-old EV.

The name change isn’t enough. What the Q8 e-tron really needs is a massive leap in its Vorsprung durch Technik in a rapidly evolving electrified landscape.

 Very good… but far from great.

If you can get past the relatively steep asking price, the design appeals to you, and its slightly last-gen ergonomics work for you, then there’s a lot to like about the GLE. It’s a big, capable and comfortable cruiser, but given there are cheaper and more efficient options around, it would be a decision of the heart rather than the head.

The Q8 e-tron looks smaller than it actually is, with the SUV wagon’s length/width/height/wheelbase numbers measuring in at 4915/1937/1633mm/2928mm, respectively.

The Sportback version is slightly lower at 1619mm.

You’ll need a keen eye to spot the difference between the old e-tron and new Q8 e-tron, with almost all of the visual changes reserved for the front end.

For starters, there’s a new, two-dimensional four-ring logo that looks larger and flatter than before, sitting within a sleeker and slimmer grille treatment that now takes in the restyled headlights. Along with the redesigned bumper, the effect serves to broaden the SUV’s stance.

The effect also suggests improved aerodynamics, aided by small air foils near the wheel arches and a fully-clad underbody section.  

Otherwise, aside from the odd inclusion of the make-model name on the B-pillar and minor trim updates out back, the Q8 e-tron keeps the same, contemporary appearance of its predecessor. Which is no bad thing. 

And there are even fewer changes inside.

The GLE hasn’t changed massively since 2019, but sleeker lights and some tweaks around the face have helped it age relatively gracefully. As much as a 2.4-tonne SUV can be graceful.

There are still references to the original ML-Class the GLE succeeded, like the ‘coupe’ shape of the C-pillar that betrays the true SUV shape of the GLE.

The reshaped front-end has less black plastic on show, and its grille stays true to the pre-facelift design.

Inside, it’s just the steering wheel that’s new, everything else holds up well in terms of a design that’s also practical, though some would say it looks outdated given the many physical controls.

More than merely good enough.

Entry and egress are easy thanks to a lofty ride height and wide-opening doors. Once sat, you’ll discover Audi has not changed anything much inside compared to the old e-tron. Frankly, very little needed to.

You’ll still find a strikingly stylish and upmarket cabin offering sufficient space for five people, a commanding driving position, superbly supportive front seats that are a boon when long-distance driving, plenty of storage options, ample ventilation and suitably moody lighting.

While not the most modern dash on the market when contrasted to the vast ‘hyper’ screens of some rivals, the Q8 e-tron’s remains very architectural in appearance and presentation.

Trim and material quality are certainly up to brand expectations. Practicality remains a priority, with lots of storage areas within the dash, console and door cards.

There are no fewer than three screens – a 12.3-inch digital instrument cluster Audi calls 'Virtual Cockpit', a 10.1-inch central multimedia display with haptic feedback and an 8.6-inch unit for climate control.

While they may seem daunting at first, a little familiarisation means most users will find them easy to operate.

Kudos, too, to the super-clear markings in the instrumentation, as well as the very satisfying tactile sensations of using the quality switchgear and controls. Typical Audi thoroughness here.

The same applies to the Q8 e-tron’s roomy and pleasantly-presented back seat area, with intelligently designed seating offering a nicely angled backrest as well as supportive cushion.

Three people can fit across without too much pain, though two is better, as the folding centre armrest and other amenities like air vents and climate control systems can be better-accessed and enjoyed.

You can see, smell and feel where your money’s gone inside. This is a quiet, isolated and cocooning experience, whether cruising on the motorway or stuck in heavy urban traffic. As you’d expect from a luxury SUV.

About the only real jarring aspect are the $3500 virtual exterior mirrors, created to improve aero performance. Their door-mounted screens are set low, outside the natural visual eyeline of the driver, creating confusion and adding precious extra seconds of eyes not on the road ahead. They’re irritating to the point of frustration.

Otherwise, the Q8 e-tron gets the job done inside, with cargo capacity at a reasonable 569 litres in the SUV wagon and 528L in the Sportback. And there’s even a 62L tub in the frunk up front to store the cables that also come standard with the EV.

Audi interior and packaging expertise strikes again.

The GLE is very easy to use because of those physical controls.

Save for the trackpad in the centre console that can be used like a laptop’s control mat - it’s a little fiddly - everything is easy to locate and adjust and the controls feel nice. The switches along the climate control row all feel nice and clicky, buttons in the centre console are big and obvious, and even the steering wheel’s haptic buttons are laid out sensibly.

The touchscreen’s software has been updated since launch during the facelift and it’s easy to navigate, but wireless Android Auto or Apple CarPlay are a good workaround.

The front seats, as well as being comfortable, are adjustable to an impressive degree for finding your driving position and there’s plenty of room and light to make the cockpit feel airy.

Storage isn’t at a premium, there’s plenty of space in door cards, the central storage bin, and the cupholders and phone charger can be hidden away.

Behind the front row, rear seat space is ample, though if you opt for seven seats the second row can be moved to accommodate a third row of passengers when needed.

In our test car, that isn’t the case, so the GLE’s cavernous 630 litres of boot storage is available. The second row can split 40/20/40, which is convenient for loading long items while four passengers are present.

Oh, but under the boot floor, despite some extra room for bits and pieces, no spare tyre. Big marks down for a car that absolutely has the space for one.

It’s not a strong start for the GLE. Our top-spec (non-AMG) GLE 450d 4Matic variant starts from $154,900, before on-road costs, while our test car has $3800 of option boxes ticked.

So, $158,700 before on-roads as-tested, the GLE is this borderline prohibitively expensive for what it offers.

If the car you’re after must be diesel, the options are still many in terms of rivals… especially if you’d like to save a few dollars.

Moving on from the big Mazdas and VW Touaregs to the proper premium badges, and there’s the $136,815 Audi Q7 50 TDI (if we exclude the $120,530 base Q7 TDI) or the BMW X5 30d for $138,600. Even a Range Rover Sport D300 comes in under the GLE at $159,481.

For a seven-ish year old luxury SUV, the GLE does a decent job of hiding its age in some ways, but there are gaps.

The twin 12.3-inch screens for multimedia and driver display have aged well, plus there’s electrically adjustable leather front seats with heating, though the leather in our new test car needs some softening up. Perhaps over time.

The new steering wheel comes thanks to newer models in Merc’s line-up, though haptic controls can be accidentally bumped (as opposed to buttons).

Wireless phone charging, wireless Android Auto and Apple CarPlay, a head-up display, a huge sunroof, LED interior lighting, adaptive high beam headlights, a power tailgate and surround-view parking cameras are all standard.

Optionally, there’s a set of 21-inch wheels as pictured on our test car. They’re $2400 and you’d probably be better off with standard 20-inch wheels for the extra comfort.

The illuminated running boards are a $1400 option, and they’re also probably not necessary. But I’m not your mum, go for it if you want.

Oh, and you can also have the GLE in seven-seat form, but our test car is a luxuriously spacious five-seater.

Tech-overload alert. As per its predecessor, the Q8 e-tron 55 continues with two electric motors – one on each axle – for ‘quattro’ all-wheel drive.

Upgraded internals are said to improve efficiency substantially. Both are induction/asynchronous motors, mated to a single-gear two-stage ratio planetary transmission.

In the 55 model, the dual-motor set-up delivers a combined 300kW of power and 664Nm of torque, for a healthy 0-100km/h sprint-time of 5.6 seconds, on the way to a 200km/h top speed.

That’s impressive, given the lightest Q8 e-tron 55 tips the scales from 2595kg. That said, the Audi’s power-to-weight ratio is an equally strong 116kg/tonne.

Other updates include more direct steering, stiffer front suspension and retuned chassis controls.

Suspension is a five-link arrangement all-around, with adaptive air suspension featuring an electronically controlled with continuously variable adaptive damping system.

The GLE 450d’s 3.0-litre inline six-cylinder diesel engine is turbocharged, with a healthy 270kW and a brawny 750Nm to its name. That torque peaks all the way from 1350rpm to 2800rpm, by the way. Handy.

A nine-speed automatic transmission sends drive to all four wheels ('4Matic' in Merc-talk), while a 48-volt ‘mild-hybrid' system ('EQ Boost' in Merc-talk) means take-offs and shifts are aided by a bit of electric power.

Mercedes says the GLE can dispatch the 0-100km/h sprint in just 5.6 seconds, and that feels about right.

The good news is that the lithium-ion battery pack size rises from 95kWh to 114kWh, and is accompanied by faster DC charging capability, due to a jump from 150kW to 170kW.

While far from the class best, this cuts down charging times by a considerable margin.

The claimed driving range is 454km, while average consumption is a disappointing 25.6kWh/100km. The Q8 e-tron’s trip computer during our run in it recorded a mid-to-high 20s readout, by the way.

Mercedes claims a 7.4L/100km combined cycle (urban/extra-urban) fuel consumption figure for the big lug, but achieving that and making the most of its large 85-litre tank is a challenge.

We averaged 8.7L/100km on test but the trip computer showed as low as 8.0L/100km at one point. Get the GLE on the highway and fuel use plummets.

Theoretically you should be able to get about 1150km from a single tank, but realistically we wouldn’t plan trips any longer than 900km between fuel stations. 

Still impressive, given that’s about the distance between Melbourne and Sydney, or Sydney and Brisbane. Roughly.

For decades, Audi used the advertising tagline ‘Vorsprung durch Technik’ – which means Progress through Technology in its native German – to highlight how advanced its vehicles are.

So, how has the Q8 e-tron advanced over its predecessor?

Right from the get-go, there’s so much to dig about the electric Audi SUV, especially if you’re new to luxury EVs.

To start with, it’s as quiet as you’d expect, even by luxury brand standards. As the Audi accelerates, the sense of momentum is somewhat masked by how refined and civilised your progress is.

Watch that, though. You could get a speeding fine more easily than you expect!

Anyway, with 664Nm of torque coming on instantly, there’s certainly no shortage of it, backed up by enough muscle for effortless and instantaneous overtaking. This sort of motoring can become highly addictive.

Similarly, a low centre of gravity, combined with a beautifully modulated electric power steering and the quattro AWD set-up, provides pleasing agility combined with reassuring roadholding. Even when you’re pressing on, the Q8 e-tron corners and grip with confidence and control.

So far, so good. Especially considering the air suspension is further cushioning your sense of speed, with excellent bump absorption for an isolated ride.

That’s on the standard 20-inch alloys spec. Riding on the larger wheels, there is a bit more firmness, as well as some road-noise intrusion.

Plus, it doesn’t take long to realise the Q8 e-tron is a very heavy vehicle. Though undeniably quick and athletic, changing directions in a hurry means that the SUV can feel a bit unwieldy.

Throttle response at higher velocities can seem a little muted and, over certain crests and humps when travelling fast, there is a sense that the driver really needs to have their wits about them.

Best to take it a bit easier, then, and enjoy the serenity the Audi EV SUV delivers in more typical and restrained travelling scenarios.

There is so much that the Q8 e-tron brings, and driving it normally really does reveal a sophisticated, comfortable, dependable and high-quality grand-touring experience.

Push a bit harder, though, and some cracks show up.

A trip in the GLE feels like a welcome step back in time. Sure, coming in close to five metres long and two-and-a-half tonnes means it’s not a nimble steer, but the GLE strikes a nice balance of comfort and tactility that’s getting rarer.

None of it feels particularly sharp in terms of inputs or feedback, but it’s easy and predictable to a point where even winding back-roads are effortless to flow through.

The big diesel engine feels almost lazy, but it’s just so effortless in getting things moving as it strives to sit close to idle whenever possible. Because of that, there’s little noise from the engine bay even under reasonable acceleration, and the powertrain is helped by that 48-volt system which makes stop-starts from the lights super-smooth.

The mild-hybrid also helps smooth out power delivery, to the point where the only time the GLE feels clunky is the occasional lag when shifting from Drive to Reverse or vice versa.

The test car’s suspension isn’t the optional airbag set-up, but the non-adaptive steel does fine in terms of comfort and soaking up harsh surfaces. And even the big 21-inch wheels aren’t too bad over sharp bumps.

With smaller wheels (more tyre cushioning) and the air suspension, it feels like the GLE would ride gorgeously.

Its body control is predictable on smooth roads, and if you’re careful you steer the hefty SUV through tight, winding roads easily, but consistently rough surfaces can make the GLE feel unsettled for a short period of time.

There’s an overall softness to it that means gentle off-roading is possible, and the tyres are thick enough to make it comfortable. You won’t find yourself being tossed around on a flat enough gravel road.

There’s a lot under the skin in the GLE in terms of safety, and it doesn’t always make itself known. This is a compliment.

The GLE scored a maximum five stars in its ANCAP assessment in 2019, and though the criteria has changed significantly since then, it feels like it should still score well.

The GLE doesn’t intervene unless it needs to, but the ability is there for the big Merc to avoid incidents and employ many means to protect passengers and pedestrians alike.

A warning for the driver and a gentle seatbelt tension comes in before the car slams on the brakes, though if no action is taken before an expected collision the GLE will drop its AEB anchors.

There are nine airbags if it all goes pear-shaped, plus some well-tuned adaptive cruise control with lane keep assist and departure alert, there’s traffic sign recognition with that, too.

Blind spot warnings, front- and rear cross-traffic alert, front and rear parking sensors and driver monitoring are joined by Mercedes’ plethora of other little safety features that minimise impact and damage in a crash.

Audi provides a five-year/unlimited kilometre warranty as well as six-years’ worth of free roadside assistance, which is nothing unusual these days, while the battery warranty is eight years or 160,000km.

The first six years of scheduled servicing is free, too. Intervals are every two years/30,000km (whichever comes first).

Plus, owners also receive six years of complimentary access to Chargefox’s network.

Servicing isn’t cheap at Mercedes, even in the context of this market segment. A three-year service plan for the GLE costs $4045, while five years is $8055. That’s $1348 or $1611 per service respectively. The later services in those five years will of course be much more expensive and bring the average up.

Intervals are every 12 months or 25,000km, but Mercedes’ five-year/unlimited-kilometre warranty means anything major that goes wrong in that time should be covered - always read the fine print.
