Mercedes-Benz E53 vs Audi e-tron GT

What's the difference?

As it turns out, the automotive world really doesn’t need an E63 S Coupe, because the E53 Coupe really does give you all you’ll ever need.

Simply put, the E53 Coupe’s balance of performance and luxury is bang on, while an E63 S Coupe would arguably prioritise one too much over the other.

Indeed, if you’re interested in a ‘relatively affordable’ grand-tourer that can get up and go when required, you could do a lot worse than the E53 Coupe.

The e-tron rightfully takes its spot at the top of Audi’s range. It’s a harbinger of all things electric in the performance realm for years to come and to look at, touch, and feel, it’s Audi all the way through.

The spirit of the Taycan also lives here, though, so while it’s a little less imposing to look at, it’s almost every bit as impressive to drive, making it compelling if you’re looking for an early slice of what performance electric motoring can look like.

Our pick of the range? The base is really all the GT car you could ever need, but at the end of the day most buyers will opt for the RS anyway...

The E53 Coupe already had an alluring exterior design, but in facelifted form, it looks even better.

The big changes are up front, where the E53 Coupe now has Mercedes-AMG’s signature Panamericana grille insert, with the multi-louvre aesthetic previously the reserve of its ‘63’ models.

In fact, the entire fascia has been redesigned, with the grille flipped upside down, while the Multibeam LED headlights are flatter and therefore angrier. Naturally, the bonnet and bumper have been tweaked to match, with the former featuring strong powerdomes.

Around the swoopy sides, a sporty set of black 20-inch alloy wheels is new, matching the window trim, while the only differences at the rear are the fresh graphics of the LED tail-lights.

Yep, the E53 Coupe still has a subtle bootlid spoiler and a prominent diffuser insert, which integrates the quad round tailpipes of its sports exhaust system.

Inside, the midlife facelift really makes itself known with its new flat-bottomed steering wheel with capacitive buttons and haptic feedback. This set-up is… fiddly, with presses often confused for swipes, so it's not exactly a step in the right direction.

And that’s particularly annoying because these controls are used for the carryover 12.3-inch touchscreen and 12.3-inch digital instrument cluster, which are now powered by Mercedes’ MBUX multimedia system, which bundles in Apple CarPlay and Android Auto support.

While now familiar, this set-up remains the benchmark in nearly all regards and is therefore a brilliant upgrade for the E53 Coupe, thanks to its speed and breadth of functionality and input methods, including always-on voice control and a touchpad.

Materials-wise, Nappa leather upholstery covers the seats and steering wheel as well as the armrests and door inserts, while Artico leatherette trims the upper dashboard and door shoulders.

Conversely, hard, shiny plastics adorn the lower door panels. Given that ‘cow hide’ and other soft-touch materials are used on most other surfaces, it’s unusual that Mercedes-AMG didn’t go the whole way.

Elsewhere, open-pore wood trim features prominently, while metallic accents brighten things up alongside the sporty stainless-steel pedals and smile-inducing ambient lighting.

I was an e-tron doubter. When I first saw pictures of Audi’s flagship electric offering I thought it took the brand’s oval formula to the extreme, with the silhouette of a bar of soap on wheels.

Up close and I couldn’t have been more wrong. The e-tron is spectacular to gaze upon, with awesome details which really cement its place at the top of the brand’s performance range.

The best angle is by far the rear three-quarter, the imposing stance of this car, the way its glossy rear diffuser lifts up to reveal the ultra-wide track of its rear wheels, and the enormous ‘blisters’ which curve over the rear arches are elements poorly communicated in pictures.

When seen up close, though, it leaves no doubt of this car’s aggressive intent and alludes to its on-road prowess.

The rear light fittings, which look flat and like any other Audi in the pictures, are all alluring and three-dimensional in reality.

The side profile has elements of RS7 in there, touches of Taycan, but a signature overall Audi shape, with the most interesting element being the wheel designs.

Like many new EV wheel designs, they’re optimised for aerodynamics, and consist of alloy elements with plastic hubcap-like pieces integrated into them.

The ones on the RS in particular have an interesting effect of looking entirely different depending on how close you get.

The black contrast elements serve to shrink the car from a distance, making it look less intimidating than its Taycan relation.

The front is the least complex part of the car, but the way Audi’s designers have managed to blend the blanked-out grille but maintain the contrasting face shape it shares with the combustion range is admirable.

It doesn’t scream ‘electric’, but subtly blends the best parts of both worlds. I like it.

Inside is equally impressive. I like it almost as much as the rear haunches, if only for the fact that it feels like an Audi, and not just a re-skinned Porsche, which is what I was expecting.

Instead, the flat, minimalist, and almost retro appeal of the Taycan is swapped for a dash design more deeply three dimensional in the e-tron GT, complete with signature Audi elements like a rhomboidal theme, angular detailing, and flush-set screens.

All the materials and buttons feel properly Audi, as well as the refreshingly simple three-spoke wheel which the GT shares with the e-tron SUV.

Personally I wasn’t sure about the Alcantara finishes on the wheel or centre console of our RS test-car. They look nice now but won’t in a few years with enthusiastic use. I’ve seen enough older performance cars to know the Nappa leather is the better choice.

Measuring 4835mm long (with a 2873mm wheelbase), 1860mm wide and 1430mm tall, the E53 Coupe is a genuinely large car, which is great news for practicality.

The boot has a pleasing cargo capacity of 425L, but it can be increased to an undisclosed volume by stowing the 40/20/40 split-fold rear bench via the handy manual release latches.

It’s worth noting that while the aperture is wide, it’s not tall, which could be a problem for bulkier items alongside the tall load lip, although two tie-down points are on hand for securing loose items.

However, what really impresses is the amount of space inside. While the front sports seats are comfortable, the two rear passengers are in for the bigger treat, with room plentiful, mercifully ending the argument of who gets stuck in the uncomfortable second row.

Behind our 184cm driving position, there’s two inches of legroom as well as an inch of headroom, although toe-room is almost non-existent.

Being a four-seater, the E53 Coupe divides its rear occupants with a tray that contains two cupholders, while they also have access to two side cubbies and a small central cubby with two USB-C ports. This cubby is positioned between the air vents at the rear of the centre console.

And yes, even child seats can be fitted, with two ISOFIX and two top-tether anchorage points available should they be required. In fact, the long front doors make this task less challenging, although those big doors do become problematic in tight carparks.

All of that’s not to say occupants in the first row aren’t treated well, because they are, with the centre console’s cubby featuring two cupholders, a wireless smartphone charger, a USB-C port and a 12V power outlet.

Other storage options include the decently sized central bin, which contains another two USB-C ports, while the glovebox is also of a decent size, and then there’s the overhead sunglasses holder.

As with most performance cars, there are some wins and losses here. The e-tron GT gets off to a rolling start though with its front seat (let’s be honest, this is where the action is meant to happen anyway), offering great adjustability, a sporty low position, and plenty of headroom and arm space for the front two occupants.

On the downside, storage space isn’t as stellar as I’ve come to expect on cars with new EV platforms. Most of this is down to the GT’s intent as a sports machine first, with low-set seats meaning less room to carve out for batteries under the floor, and hence less storage cutaways down the centre.

The two cupholders are nice and big, and the console armrest box is okay, complete with a little side-mounted wireless charger, but the door pockets are embarrassingly small with no bottle cutouts, and there’s precious little storage elsewhere.

The low seat and curvy roof means you have to duck down low to get in, and oddly the big fixed sunroof doesn’t have a retractable shade, so this car is going to get hot being left out in the Aussie sun.

The screens, as usual with Audi products, are a highlight, offering super fast, sharp hardware, and attractive and functional software, with the only real downside being some of the touch areas when phone mirroring can be quite small with such a high-resolution screen.

The back seat lays claim to this Audi’s big EV party trick, the fact that there are sizeable cutouts in the under-floor battery pack so adults can enjoy usable legroom.

It works. I have airspace for my knees behind my own seating position, and headroom is surprisingly good, too.

Technically the e-tron GT is a five-seater, but the centre rear position is all but useless, at least for adults, as it is very narrow.

There’s nowhere to put your feet thanks to a raised centre floor to facilitate additional battery space, almost like a transmission tunnel in a combustion vehicle.

Rare amenities for rear passengers include two USB-C ports and a third climate zone with a control panel, although, unlike some EV rivals, there’s no full-size household power outlet.

Boot space comes in at 350 litres which isn’t huge considering the e-tron GT’s rather large footprint.

As a result it could only hold two of our three CarsGuide test luggage cases. There’s no under-floor storage here, although you do get an elastic net.

The GT also scores a surprisingly large under-bonnet space, perhaps a good spot for keeping your charging cables.

There are two forms of the Audi e-tron GT, the regular GT version with prices starting from $180,200, or the full-fat RS, which takes a healthy jump to $248,200 along with a corresponding rise in performance and standard equipment.

Audi promises the e-tron GT is better value than its Porsche Taycan rival like-for-like, starting with all-wheel drive only as opposed to the Taycan’s rear-drive base-spec.

For those worried about EV value, consider the e-tron GT is both faster and much more affordable than the R8 was before it was discontinued in Australia last year, with the latter starting from a whopping $316,377, before on-road costs, before it met its end.

Taking its spot at the helm of Audi’s range, the e-tron GT certainly doesn’t want for standard gear, with equipment on the base version including 20-inch alloy wheels, adaptive air suspension, a fixed glass roof, LED matrix headlights, a 12.8-inch digital instrument cluster and 10-inch multimedia touchscreen with wireless Apple CarPlay and Android Auto, a 710-watt audio system, and of course all the expected safety gear.

The standard GT variant is slightly less powerful than the RS with its dual-motor set-up producing ‘just’ 350kW/630Nm, but maintains the rather unusual two-speed transmission and, of course, the all-wheel drive system.

Let-downs for this model include the surprisingly average feeling synthetic leather seat trim, and the plastic filler panels adorning the dash which the RS replaces with much more attractive carbon-look inserts. These are no deal-breaker for sure, but the seat trim in particular feels a bit rude on a vehicle which costs over $180,000.

The RS e-tron GT meanwhile ups the power to a whopping 440kW/830Nm, increases the standard wheel size to 21-inch, adds actual Nappa leather seat trim with an additional ventilation function, as well as an all-wheel steering system, rear differential lock, upgraded laser headlights, and tungsten carbide brakes as standard.

The car we primarily tested for this review had further options, taking the price to nearly $280,000, including a more hardcore carbon ceramic brake package, coming in at a staggering $12,500.

The e-tron GT also offers an extremely rare option in the world of EVs, a 22kW AC charging inverter ($6900), which makes it the fastest charging car in Australia on this standard. Good luck finding a public outlet which will actually go that fast.

Thanks to its heavy-duty 800-volt battery hardware, it is also one of the fastest charging electric cars in Australia, full stop. More on this in the charging part of this review.

The E53 Coupe is powered by a 3.0-litre inline six-cylinder petrol engine that produces a hearty 320kW of power at 6100rpm and 520Nm of torque from 1800-5800rpm.

The unit in question has one traditional turbocharger and an electric-powered compressor (EPC), which is available at engine speeds up to 3000rpm and can spool up to 70,000rpm in just 0.3 seconds for instantaneous punch.

But that’s not all, because the E53 Coupe also has a 48V mild-hybrid system called EQ Boost. As its name suggests, it has an integrated starter-generator (ISG) that can provide up to 16kW and 250Nm of temporary electric boost.

Mated to a nine-speed torque-converter automatic transmission with redesigned paddle-shifters, and Mercedes-AMG’s fully variable 4Matic+ all-wheel-drive system, the E53 Coupe sprints from a standstill to 100km/h in a handy 4.4 seconds.

The e-tron GT is stupidly powerful. The 350kW/630Nm available in the base GT allow a 0-100km/h sprint time of just 4.1 seconds, while the even higher 440kW/830Nm available in the RS reduces that to a mind-melting 3.3 seconds. Not bad for a car which weighs nearly two and a half tonnes.

Like the Taycan, the e-tron GT sports a two-speed transmission, with the low gear primarily used in sport mode as a take-off ratio, with the second made for highway cruising or when the car is set to 'Eco' mode.

Two electric motors allow for fully adjustable all-wheel drive to enhance handling while the RS goes a step further with its subtle all-wheel steer system and locking rear differential which enhances its agility at both low- and high-speeds even further.

The E53 Coupe’s fuel consumption on the combined-cycle test (ADR 81/02) is 9.3L/100km, while its carbon dioxide (CO2) emissions are 211g/km.

Given the performance on offer, both claims are pretty good. And they’re made possible by the E53 Coupe’s 48V EQ Boost mild-hybrid system, which has coasting and extended idle-stop functionality.

That said, in our real-world testing, we averaged a more realistic 12.2L/100km over 146km of driving, although the launch test route only involved high-speed country roads, so expect a higher result in metropolitan areas.

For reference, the E53 Coupe has a 66L fuel tank, and it will only drink more expensive 98RON premium petrol.

There is just one massive battery in the e-tron range, a huge 83.7kWh (net) lithium-ion unit. This grants the GT a driving range of 540km to the more lenient NEDC (rather than WLTP) standard, while the RS scores 504km of range.

The battery is an 800-volt unit, with an integrated water-cooled design which helps the e-tron GT join the Taycan, Kia EV6, and Hyundai Ioniq 5 as one of the fastest-charging EVs on the market.

On a compatible DC charger which can hit this car’s 270kW peak, the e-tron GT can charge from 5-80 per cent in just 22 and a half minutes.

To help this process along, setting the destination to a charger in the car’s built-in navigation will help to pre-condition the battery to ideal charging temperatures.

Other impressive charging specs include the option to install a 22kW AC inverter, bringing the ‘slow charging’ time down to just four hours if you can find a compatible unit.

Otherwise the standard rate is an acceptable 11kW. The e-tron GT is also one of the only EVs on the market with AC charging outlets on either side, ensuring you won’t have to stretch to reach the nearest charging port.

The downside of all of this is the fact the e-tron GT, like its SUV sibling and Porsche Taycan relation, has a comparatively high energy consumption.

The official numbers are 19.2kWh/100km for the standard GT, or 20.2kWh/100km for the RS. These numbers are already high, but we saw significantly higher again on our test route.

While you probably won’t be driving the car as thoroughly during the every-day commute, I have experienced similarly high numbers in the mid-20kWh/100km range in the e-tron SUV during standard weekly testing, so expect similar. Good thing it charges quickly.

If an E53 Coupe was your daily driver, you’d be very happy, because its balance of comfort and performance is just about as good as it gets.

Stick the boot in and the engine responds with a level of enthusiasm that only electrification can provide. Not only does the ISG provide timely thrust, but the EPC helps the E53 Coupe reach its maximum torque, although it has to work harder for peak power.

That said, despite the addition of the EQ Boost system and the EPC, the E53 Coupe still feels like a proper Mercedes-AMG model, staying true to the high-performance mantra while offering a different approach.

Critically, all the drama is there, as it charges towards the horizon with intent as the transmission swaps gears smoothly, providing relatively quick shifts and revving on the down changes when required. It all adds up to a properly exciting drive.

However, it’s the E53 Coupe’s sports exhaust system that’s likely to command all the attention with its crackles, pops and overall booming soundtrack in the Sport mode. It can also be manually engaged in any mode by pressing a button in the centre console.

And given the E53 Coupe’s 4Matic+ system is fully variable, it offers plenty of grip when briskly accelerating and enjoying the soundtrack, but its rear end can still step out briefly when cornering hard.

Speaking of handling, the E53 Coupe goes around corners surprisingly well, defying its large dimensions and considerable 2021kg kerb weight by exhibiting strong body control.

Coming into bends, the E53 Coupe can also lean on its sports brakes, which pull up with absolute confidence.

And when you’re guiding the E53 Coupe through the twisty stuff, the electric power steering comes to the fore, with its speed-sensitivity and variable ratio.

The steering set-up is somewhat disappointing at times, however, with the feedback not quite up to the level of a proper performance car.

That said, it is quite direct and feels meaty in hand – two traits that are necessary for success – with this heft increased in the Sport drive mode. Comfort is where it’s at, though, if you ask me.

That said, the E53 Coupe’s suspension uses air springs and adaptive dampers to make it a comfortable cruiser.

Sure, this set-up’s tune does prove to be a little firm on lower-quality country roads, with most bumps and lumps felt by occupants, but on well-maintained highways and city roads, it’s got suitable levels of smoothness.

In keeping with this luxurious feel, the E53 Coupe’s Noise, Vibration and Harshness (NVH) levels are pretty damn good, with tyre roar and wind whistle easily missed while enjoying its aforementioned Burmester sound system.

You’re probably wondering if you can even see out of the e-tron GT given its low-set shape and seemingly small windows, but the answer is yes. Mostly.

There’s decent visibility out the front with surprisingly good mirror coverage to see out the rear, although the rear window is a bit hopeless, offering just a letterbox aspect of what’s behind you.

The seating position is excellent, though, allowing you to sit nice and close to the ground, rare for an EV.

It feels every bit the sports car it claims to be, and when you step on the accelerator pedal it is ridiculously, enormously fast.

Even if you’re already at velocities higher than 100km/h, the e-tron can draw from a well of seemingly limitless torque to jolt you forward even faster.

One of its most impressive traits, and I think the e-tron GT shares this with the Taycan, is how the car seems to shrink the faster you drive it.

Particularly in RS trim with the four-wheel steer, this doesn’t feel like a two-and-a-half tonne, five-metre long grand touring monolith, responding to your inputs with the agility of a much lighter two-door coupe.

It ducks and darts around corners, and while its steering seems to have a noticeable artificial component, regardless of drive mode, the all-wheel steer isn’t as invasive as you think it’s going to be.

In fact, it’s only noticeable when driven back-to-back with the base car which doesn’t have it, with the RS having noticeably better road holding with the tech equipped.

It furiously holds onto corners, with the electric all-wheel drive and fat tyres keeping everything under control. You have to be really irresponsible in this car to get the tyres to even scream out in pain, let alone slip, a feat I suspect 90 per cent of buyers won’t come close to experiencing.

These observations, mind you, come from exclusively on-road use of the e-tron GT. It will be curious to see how it handles more punishing conditions on-track, for the rare set of buyers this will appeal to.

For those keeping it to road-use, the adjustable air suspension grants pretty impressive ride quality considering the size of this car’s wheels and its overall weight.

It’s excellent at smoothing out corrugations and shrugging off smaller bumps, but when dealing with bigger hits this car can’t quite hide its limitations. Things go from ‘ooh’ to ‘owch’ very quickly as the dampers and bump stops intervene.

On the whole though, this car is hugely impressive. Does it feel like a Taycan? Yes, actually. This is one area where the two EVs feel their most similar. But the Taycan is awesome, so this is high praise for the Audi.

All the key active gear is present, and refreshingly, aside from the arguably unnecessary laser-equipped LED headlights, nothing is on the options list.

The e-tron GT is equipped with autobahn-speed auto emergency braking with vulnerable road user (cyclist and pedestrian) detection, as well as intersection assist.

There is also lane keep assist with lane departure warning, adaptive cruise control, and blind-spot monitoring with rear cross-traffic alert and rear auto braking.

This combines with the clever all-wheel drive system and array of front, side, and curtain airbags to make for a theoretically safe car, although the e-tron GT is yet to be rated by either ANCAP or EuroNCAP.

Like all Mercedes-AMG models, the E53 Coupe comes with a five-year/unlimited-kilometre warranty, which is currently the benchmark in the premium market. It also comes with five years of roadside assistance.

Better yet, the E53 Coupe’s service intervals are rather long, at every year or 25,000km – whichever comes first.

It’s also available with a five-year/125,000km capped-price-servicing plan, but it costs an expensive $5100 in total, or an average of $1020 per visit, with the E53 Coupe’s fifth trip charging $1700 alone. Ouch.

Audis now have a competitive five year and unlimited kilometre warranty, and the e-tron GT also scores a separate and industry-standard eight-year warranty for its high-voltage battery components.

The additional ownership perks for this car are significant, however. Audi throws in complementary installation of a 7.2kW wall charger at your home, as well as a six-year Chargefox membership, making your energy consumption free from public outlets for the first six years of ownership.

There’s also free servicing for six years (covering the first three bi-annual or 30,000km visits). A truly premium car with no truly premium service costs? What’s not to like about that?
