Audi e-tron GT vs Mercedes-Benz AMG GT

What's the difference?

Anyone lamenting the demise of V8 and V10-powered internal combustion sports cars will change their mind after driving the Audi e-tron GT.

It is a phenomenal car and you can feel the engineering expertise that’s gone into making it. 

The e-tron GT feels at home on German roads and autobahns, but a drive on Australian roads could well reveal some flaws. We will wait and see.

Until then, the e-tron GT is one of the most deeply impressive cars I have ever driven. And if you’re fortunate enough to be able to afford a car like this, perhaps it’s your next (very fast) family car?

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

The GT63 4Matic+ is a breathtaking example of everything that Mercedes-Benz and AMG are.

Ferociously fast, incredibly agile and superbly sophisticated, it should be on anybody’s shortlist, if that also includes a Porsche, Aston Martin, Maserati or even a Lamborghini. And it’s definitely much more than yesterday’s SLC ever was – for similar money in today’s terms, as it turns out.

But, around Tasmania’s glorious roads at least, the Mercedes-AMG lacks the ride comfort and road noise isolation to be a fully-rounded-out GT, and that’s a disappointment for a brand with such formidable history in making such cars.

You could argue the e-tron GT was already a stunner and didn’t require any visual changes, but Audi has still made a few tweaks. Thankfully, they are relatively subtle.

The 2025 e-tron GT gains refreshed front-end styling with a new front grille, headlights and lower bumper and air intakes. The look is inspired by Audi’s latest design language as seen on the recently revealed A6 Avant e-tron.

The S has more subtle front and rear styling, while the RS and RS performance take on a more aggressive and sporty look with a dramatic rear diffuser and different lower front styling. 

The RS performance further differentiates itself from the RS with an optional matt, darkened carbon roof and optional ‘carbon camouflage’ elements found in the embossed bumper, door trim, parts of the diffuser and side mirrors.

Audi has introduced some rather gorgeous new alloy wheel designs, some standard, some optional.

I had forgotten how stunning the e-tron is in the metal. You can see by its stance that it’s related to the Porsche Taycan - they share the 'J1' platform.

Despite the low-slung sports sedan vibe, they have their own distinct identities. If you’re after elegant clean design, you’ll likely favour the Porsche. But I am increasingly leaning towards the Audi on the design front.

Inside you get redesigned sports seats, a new steering wheel and fresh inlays, including sustainable wood on some grades. I love the new steering wheel, covered in Audi’s version of synthetic suede. BMW take note - you don’t need a big chunky steering wheel in a performance car. This rim is just right.

There’s new readout and graphics for the digital driver display and the carpet and floor mats are made of 100 per cent recycled nylon fibres. Audi’s used synthetic suede and leather throughout, and the non-leather grey cloth trim in the S is a knockout. But you can get real leather if you want.

Some of the grades we drove at the launch event come with Audi Exclusive elements which add unique touches and colours chosen by the customer, from the interior inserts, trim, stitching and more. Audi Australia isn’t saying too much but some of these Exclusive options might end up here eventually.

This is still clearly a Mercedes AMG GT coupe, like the 2014 C190 original, but a ground-up redesign sees it subtly yet significantly altered.

Some 270kg heavier than before, the larger-in-every-dimension body combines aluminium, steel, magnesium and fibre composite materials for improved rigidity and a lower centre of gravity. Length (4729mm) and wheelbase (2700mm) have been stretched by 177mm and 70mm respectively. Width (1984mm) and height (1352mm) are also up.

The nose treatment is similar to before, especially with the bulgy bonnet and signature vertical slatted grille fitted. These, combined with the LED digital headlight shape effect, is reminiscent of, but far-better executed than, the goofy-looking MG5’s face.

Underneath, it's an all-new platform shared with the SL, with the rear transaxle of the old car replaced by a permanent AWD system, leading from 46:54 front/rear weight distribution to 50:50 as a result.

That aggressive, exaggerated cab-backward/ultra-long bonnet silhouette that visually connected it with the SLS gives way to more-conventional and practical coupe proportions that is striking if not especially original, since they do look quite 911-esque. Along with the longer wheelbase and wider tracks, the result allows for two small rear seats to be fitted, while liftback cargo access remains.

Similarly, in the name of way-more usable interior packaging, Mercedes-AMG says it pushed the driving position nearly 180mm forward compared to the previous GT. Let’s see what that all looks like inside.

The e-tron GT is a big car, so it has potential for family duties, but it’s also a sports car, and that means some compromises. 

The new front sports seats in any of the various trim options offer incredible levels of comfort, ample support and they’re well cushioned. This is a Grand Tourer so comfort is important and that box is well and truly ticked.

It’s low to the ground which helps with feeling connected to the road, and the multi-adjustable seats and steering wheel mean it’s easy to find your perfect driving position.

With the addition of new air suspension as standard, the e-tron GT has a neat trick. When you touch the door handle, the set-up automatically increases the vehicle’s ride height by up to 77mm to make it easier to get in and out of. \

Don’t expect much visibility out the tiny rear windscreen, but you can rely on the clear surround-view camera display. 

From the driver’s seat, everything comes easily to hand. The multimedia screen isn’t a stretch to reach, nor are the buttons on the stack and console. Thanks for keeping buttons, too, Audi.

Audi’s current multimedia setup is solid. It has big menu icons, logical menu steps and you can swipe across for more.

The ‘Virtual Cockpit’ digital instrument cluster is also excellent and easily customisable. The built-in sat nav shows up in multiple places if you like, such as the head-up display, instrument display or multimedia screen. During our extensive drive from Frankfurt, it didn’t miss a beat.

The optional panoramic glass roof has a cool feature. You can switch from opaque to clear with the touch of a button. And you can even have a mix of the two. Clever.

To maximise space, Audi moved the phone charger to inside the central bin. Given it is hard up against the side, it doesn’t consume that much room.

Elsewhere up front, smaller bottles will only fit in the door pockets if they are lying flat.

In a smart bit of design from Audi, the battery pack is split to accommodate deeper footwells for the rear passengers. So many electric cars, especially sedans, suffer from having the battery pack under the entire length of the vehicle's floor which means your legs sit awkwardly upright. Hello Tesla...  

As a result, you can sit like a normal human in the back of the e-tron GT, and there’s ample legroom behind my six foot-plus driving position. That’s helped by scalloping the rear of the front seats. Headroom is tight but that’s expected given the swoopy roofline. 

There’s no bottle storage in the rear doors, only enough room for a phone. You get lower air vents, seat heating controls and a central fold-down armrest with cupholders. 

The boot is long and the 60/40 split seats fold flat which is handy for loading long items. There are a number of nooks and a handy cargo net, too. Luggage space ranges from 405 litres for the S e-tron GT to 350L for the RS performance. There’s a sizeable front trunk for housing charging cables.

The first impression inside is that of space, despite the falling roofline and coupe-like upsweep of the side windows and you look back. While, again, similar to a 911s, a kink at the door gives the GT a unique character.

Even larger people will appreciate the generous amounts of room up front, with space to stretch, sat in sumptuously comfy bucket seats. Note that the standard ones are better than the racier but firmer Sports versions.

The driving position is perfect, ahead of a dashboard that is very typical modern Mercedes in appearance and layout.

To that end, the tablet-style integrated touchscreen (11.9 inches) is clear, fast and intuitive once time is taken to learn it. And points are also won for the multi-configurable electronic instrumentation, that allows for a variety of screens, including track, classic and minimalist views.

The trademark turbine air vents, the quite beautiful material and trim finishes and just the general solid feel are further typical contemporary Mercedes cabin treatments, as are the excellent ventilation and ample storage options.

And while rear vision isn't great, that's what cameras are for. It's all pretty much on brand.

It is a shame, given how elevated the Mercedes-AMG engineering is underneath, that the GT’s interior look and ambience is so similar to those of a (albeit higher-spec) C-Class or GLE. It's simply not as special as some of the company’s previous sports cars.

More annoyingly, the ride is too firm and bumpy for a GT, and this has the unhappy effect of provoking random rattly trim sounds within the cabin. It’s a bit like scrunched-up cellophane. In a $420K (as tested) Merc, that’s very disappointing, especially as it can be heard over the copious amount of road and tyre noise droning through, particularly on coarser bitumen surfaces.

Further back, the rear seat is strictly two-plus-two, and nobody over 150cm tall is recommended to travel there by Mercedes itself. That sloping roofline is the culprit. That said, brief trips with a bowed head are possible, as the fixed cushions and split-folding backrests are actually surprisingly comfy. But only for short journeys. Kids should love it though, and the second row does open up the GT’s usefulness enormously.

As does a near-doubling of the AMG’s cargo capacity, jumping 146 litres to 321L with backrests erect, to a whopping 675L (+325L) in two-seater mode. The flat floor is accessed via a large electrically-operated liftback door, offering quite a large aperture for easy loading/unloading.

Having no spare wheel helps here, with a tyre inflation kit included in lieu of that.

Meanwhile, at the front, under the bonnet, things have definitely changed for the better as well.

Starting from $370,400 (all prices are before on-road costs), the Mercedes-AMG GT63 4Matic+ is priced and positioned as something of an eagle amongst some pretty delectable doves, given its combination of four seats, 430kW of power, 800Nm of torque and four-wheel drive.

No rival equivalents can match the Mercedes on paper. The 398kW/610Nm 911 Carrera 4 GTS T-Hybrid offers less power but starts from $400,000-plus. The 410kW/650Nm GranTurismo Trofeo begins at $450K, the 500kW/800Nm DB12 from $455K and the 404kW/470Nm Continental GT from $460K.

Only the 460kW/750Nm BMW M8 Competition comes closest to the Mercedes-AMG, from $380K.

Side note, today’s GT is only slightly more expensive than what the 450SLC was nearly half a century ago when adjusted for inflation.

And, just like with that classic old Benz, it shares much with the brand’s legendary SL convertible stablemate – including, in this case, standard all-wheel drive and active rear-axle steering… aka 4WS to select third and fourth-generation Honda Prelude owners out there.

What else does $400K-plus buy you? As you’d expect, the GT63 4Matic+ comes choc-full of standard equipment, much of it typical of the luxury coupe breed, with leather-covered and electrically operated everything.

How about a front-axle lift system with GPS-enabled memory that automatically raises the GT’s nose to help clear bumps and then remembers to do so next time?

There are climate-controlled AMG sports seats with inflatable bolstering and massaging functionality, a fixed glass roof, a head-up display, augmented-reality satellite navigation, 360-degree surround views, performance telemetry data as part of an extensive multimedia system, an 11.9-inch portrait touchscreen, 11-speaker Burmester audio, a handsfree-powered tailgate, 21-inch alloys and cutting-edge driver-assist safety tech. More on that in the Safety section below.

Then there are the myriad option packs, bumping the GT63’s price up towards $500,000. These include a $2.7K seat trim package; a $10K AMG Night Package that adds darker trim treatments (often where chrome was); an aerodynamics package with fixed spoiler replacing the standard active spoiler; a $2.6K AMG Performance Seat package; a $13K Carbon Fibre package and $13.2K Ceramic Brakes.

Now, while the new GT does ditch the previous model’s unique rear transaxle spaceframe pioneered by the gull-winged SLS of the early 2010s, the resulting longer wheelbase and shorter overhangs do provide less outlandish and more practical design.

Let’s check that out in more detail. 

The fully electric e-tron GT has two motors - one on each axle, ensuring ‘quattro’ all-wheel drive traction.

For the S e-tron GT, the total system output is 430kW of power (or up to 500kW in launch control mode) and 740Nm of torque. 

That’s more power than the previous RS e-tron GT, and enough to get it from zero to 100km/h in 3.6 seconds.

The RS now pumps out 500kW (630kW in launch control mode, no total torque figure available) and can hit triple digits in 3.1 seconds, while the new RS performance flagship boasts impressive outputs of 550kW/1027Nm (680kW in launch control mode) for a dash time of 2.9 seconds. These 0-100km/h times improve in launch control mode.

A newly developed air suspension is standard across the range, and tech wizardry like active suspension and rear-axle steering are optional.

There’s a plaque signifying which engineer “handcrafted” the GT’s engine – in this case, the famous M177 in 3982cc, 4.0-litre twin-turbo intercooled V8 petrol guise.

Delivering 430kW of power at 6500rpm and 800Nm of torque from 2500-4500rpm, it sends drive to all four wheels via a nine-speed multi-clutch transmission (dubbed MCT in AMG-speak), catapulting the GT63 4Matic+ from 0-100km/h in just 3.2 seconds, on the way to a top speed of 315km/h.

How does it do that?

With AWD, the GT is now nearly 15 per cent heavier than before, but it still manages a punchy 218kW/tonne. Active aerodynamics over, inside and under a more-rigid body structure also helps.

The AMG 4Matic+ AWD system goes from 50/50 front/rear, to 100 per cent rear, variable torque distribution according to conditions and settings, and backed up by an electronic limited-slip differential. Among the many driving settings are Race Start, Drift Mode and good-old Comfort, if it all becomes too much.

Also keeping all that performance in check is a high-performance composite brake setup with improved cooling for faster responses.

Interlinked active roll bars improve body control, the five-link independent suspension features adaptive dampers for a softer ride.

And, as for that 4WS tech, the rear wheels steer opposite to the fronts at up to 100km/h (by some 2.5 degrees) for tighter and tidier handling, or 0.7 degrees in the same direction above 100, for greater stability and road-holding.

Its effect on the way this near-two-tonne coupe zigs and zags around corners is something you need to experience to really appreciate.

Audi has reduced the weight of the battery pack by 9.0kg while also increasing energy density.

Audi has also improved the charging rate which now peaks at 320kW, up from 270kW.

The 105kWh lithium-ion battery on all grades can be charged from 10 to 80 per cent in just 18 minutes using a high-power charging station, according to Audi.

AC charging is 11kW and doing that at home will take about 11 hours from depleted to 100 per cent.

The update to the information in the instrument cluster includes details about current operating state of the battery, including temperature, a quick-charging forecast and the pre-conditioning status.

Driving range is impressive and runs from up to 609km on the WLTP cycle for the S e-tron GT, up to 599km for the RS e-tron GT and up to 592km for the RS e-tron GT performance.

Energy consumption ranges from 18 to 19.7kWh/100km for the S, 18.4-21.1 for the RS and 18.7-20.8 for the RS performance.

Actually, the GT’s economy isn’t horrendous considering how fast it can go.

Even blasting a few times around beckoning country roads, we managed an indicated 13.0L/100km, which is an improvement on what Mercedes-AMG says the GT averages the 14.6L/100km average that Mercedes-AMG officially states.

That translates to a carbon dioxide emissions rating of 334g/km.

Using 98 RON premium unleaded petrol, an average of just under 480km between refills of the 70L tank is possible. The urban run sees consumption rocket to 21.8L/100km (for just 321km of range), or 10.4 out on the highway run, meaning that over 670km is possible should you decide to drive in a docile manner.

Having the air suspension increase the ride height to get into the e-tron GT is useful, given how low to the ground it is. Once you’re in, you’ll nestle into the sports seats and feel a real connection with the road.

Audi’s generated EV noise sounds like the low, deep growl of a V8, but dialled down. It’s very cool.

The new RS e-tron GT is quick but it delivers acceleration in a smooth, linear manner. There’s no neck-snapping ‘Ludicrous’ moment here. Just straight line performance that will elicit the word ‘wow’ multiple times.

Picking up pace at speed is a breeze - as we discovered on Germany’s autobahns - thanks in part to a ‘push to pass’ button on the steering wheel that adds 70kW of power for 10 seconds, when you need to overtake quickly.

The steering is sharp, but almost a little too sensitive in the RS, to the point where you need to be conscious of your steering inputs. You don’t want to overdo it, but if you do, the onboard electricals should keep things in check. That beautiful steering wheel adds to the engagement.

Audi’s engineers deserve plaudits because they’ve somehow made a five-metre long, 2.3-tonne electric sports sedan feel light and nimble. 

It is dead flat in corners without a hint of lean or body roll and navigates tight bends with a surefootedness that is astounding. 

Accelerating out of a corner is executed without fuss and will bring a smile to your dial, helped in part to the optional rear-axle steering.

The technical wizardry that is active suspension - it uses cameras and radars to analyse the road surface ahead and moderate the dampers and the like accordingly - is impressive.

The ride quality of this heavy car with 21-inch rims is a surprise. You’ll notice road joins and bigger corrugations but overall it's quite composed.

And that’s part of the beauty of the e-tron GT. Its Porsche Taycan cousin is a more focused sports car. Whereas the Audi e-tron GT is a Grand Tourer or Gran Turismo if you will.

Yes, it’s incredibly powerful and is blisteringly fast, but it’s also a comfortable cruiser, and something you could easily live with every day.

The S e-tron GT could be all the Audi you need. It’s still incredibly quick, but not as powerful as the RS. It is the more subtly styled model which will appeal to an understated buyer.

A brief stint on a makeshift track in the e-tron GT performance grade highlighted how the active suspension, rear-axle steering and other tech gubbins help it hold the road so well.

It’s an extraordinary car to drive and taking a different approach to Porsche has served Audi very well indeed.

The advanced safety gear is well calibrated and not intrusive. While the speed limit alert can be annoying, the speed sign recognition is spot on. Let’s see how it goes with Australian speed signs next year.

Nobody will drive the GT63 4Matic+ and think, ‘Oh, this is OK’, because its breadth of performance is phenomenal.

No matter which mode you're in, from Comfort through to track-tuned Race, the Mercedes-AMG blends forceful pace and commanding control without ever breaking a sweat.

Flex your right foot and the two-tonne coupe bounds into action like a giant on a mission, striding past posted speed limit signs in nanoseconds and way, way faster than the law will stand if diligence isn’t exercised.

And there’s no point relying on seat-of-your-pants sensations, either, because the chassis below embraces the road with an almost zealous devotion. Which is astounding, given how agile the four-wheel steering-enhanced handling is.

The 63’s super power is exactly that – it dulls your sense of speed. One tester admitted to exceeding 150km/h before noticing. An odd confession considering the sonic boombox that is the bi-turbo V8’s howl.

But jailbait performance is not even the 63’s most lingering joy. That would be its steering perfection, that delivers that rare trifecta of keenness, crispness and communication. The wheel feels eager and alive in your hands, even when powering between tight turns, backed up by sensational grip and control. How can a two-tonne GT handle so sharply?

Warm, dry roads were the order of the day, so we can’t tell you how the 4Matic+ permanent AWD system deals with wet or slippery surfaces, but the slick multi-clutch transmission, seamless torque-vectoring tech and sticky tyres more than cope with the 63’s formidable outputs.

So, that's the gushing part out the way, then.

Despite the adaptive dampers, rigid architecture and exquisitely sophisticated suspension, the ride is simply too stiff in Comfort mode, and downright jittery on some of the Tasmanian roads we tested on, for the 63 to be considered a true luxury grand tourer. It just isn't comfortable, luxurious or supple enough.

Plus, grippy as they are, the 21-inch wheels transmit too much road and tyre noise through to the cabin, meaning that the GT isn't as quiet as you'd hope. Add the aforementioned trim squeaks, and the expected cocooned silence isn’t always there.

The upshot is that the 63 possesses more of a sports car character than a luxury GT character. Great news if you're a 911 type buyer and are seeking a high-performance 2+2 alternative, but a disappointment if comfort and refinement are priorities.

Still, it is impossible not to be deeply moved by this Mercedes-AMG.

While the GT doesn’t score an ANCAP rating – probably because it’s too expensive to crash test – we’d wager that it would be above-average, given Benz’s track record as a pioneer in this field.

That’d due to the scores of active, passive and driver-assist safety features fitted, from multi-faceted autonomous emergency braking (AEB) and lane-support systems to Mercedes’ PRE-SAFE tech that anticipates a crash and then prepares the car for impact.

More specifically, the GT includes Active Lane Change/Keep Assist, adaptive high beam as part of its megapixel LED set-up, adaptive cruise control, Cross-Traffic Assist, Evasive manoeuvre support, an emergency services call-out system, 360-degree camera views, pedestrian protection bonnet and eight airbags.

In other Mercedes products of today, AEB operating parameters are 7-80km/h for vulnerable road users like pedestrians and cyclists, and from 7-250km/h for vehicle-to-vehicle, while the lane-keep support systems operate between 60-200km/h.

Finally, there are ISOFIX child-seat anchorages in the front passenger seat and two in the rear seats.

The e-tron GT comes with Audi’s five-year, unlimited kilometre warranty which is fairly standard for the premium segment. The battery warranty is eight years or 160,000km.

Impressively, the outgoing model comes with six years of complimentary servicing by Audi, and the schedules start at every two years or 30,000km. This should carry over for the new model but will be confirmed when the rest of the pricing and specs are locked in.

What’s the GT like to own?

Mercedes-Benz offers a five-year/unlimited km warranty, with five years of roadside assistance. This is average for most mainstream and luxury brands, but superior to most sports-car makers like Porsche and Lamborghini.

Intervals are every 12 months or 20,000km, and while no capped-priced servicing is offered on the GT, pre-paid three-, four- or five-year service plans are available, ranging from $5165, $7700 and $8665 respectively.

Big performance demands big maintenance bills, it seems.
