Mercedes-Benz CLA-Class vs Audi e-tron GT

What's the difference?

The new AMG C 43 may lack the drama and excitement we’ve come to expect from the German performance brand, but that doesn’t mean it’s a bad car. Yes, it could be more extroverted and the ride could be improved, but this is still a sharp-looking sports sedan with loads of punch.

This is a car that speaks to its times, with ever-stricter emissions regulations making it harder and harder for car companies to produce loud, wild and charismatic cars. So Mercedes-AMG has worked within those boundaries and come up with a car that retains at least some of those core elements that has made the brand so desirable over the years.

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

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...

Mercedes has created something of a problem for itself with its decision to introduce AMG styling packages for the majority of its range, including the C-Class.

It means the C 43 has to walk a fine line between looking like a unique AMG model, rather than just a C300 with a bodykit and not out-doing the C63.

To that end it has AMG’s now familiar grille with vertical bars, the unique and complex-looking 20-inch alloy rims and a small lip spoiler on the boot. But otherwise it is surprisingly understated for an AMG, lacking the more obvious and muscular stance of previous AMG offerings.

Inside, there’s a similar theme, with the typical Mercedes-Benz luxury appointments but with a sportier, AMG twist. The steering wheel is chunky and comes with AMG branding, metallic shift paddles and a pair of rotary dials/buttons that allow you to alter the various drive modes and settings.

The one on the right allows you to switch between the pre-set Comfort, Sport, Sport+ and Individual modes, while the one on the left can scroll between the various individual aspects to tailor the settings to the conditions.

In typical modern fashion the design is tech-laden, with a digital display for the instrument panel (that can be switched between various graphics) and a large, tablet-style central multimedia touchscreen that controls the majority of the car’s non-driving functions.

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.

The new C-Class has grown slightly in size compared to the model it replaces, most notably with a 26mm increase in the wheelbase which you can feel in the cabin.

The front seat space is good, with excellent adjustability for the power-adjustable seats and steering column. I had no trouble finding my ideal seating position which makes for a more enjoyable and uncompromised driving experience.

Rear space is a bit tighter (which is typical for this segment/size of vehicle), but thankfully the standard seats do have very deep sculpting in the backs which allow for more knee space and foot room.

However, at approximately 180cm (six-foot), I wouldn’t like to sit behind my seating position for long periods as my knees were touching the seat back, and headroom is compromised with the panoramic glass roof.

In terms of small item storage there’s a lidded console box in between the front seats as well as a pair of cupholders and a small tray where you can place your mobile phone.

It’s worth noting, though, that early examples of the C 43 in Australia do not have a wireless smartphone charging pad, with that reportedly being introduced from February production.

While that’s good news, it’s not really competitive in this day and age to offer a car costing six-figures without such technology.

There’s also only a single USB-C power outlet in the front, which is another disappointment, but there is a pair in the back.

Mercedes does win some points back for a respectable 455-litre boot, which has a nice wide load opening that will make packing luggage easier.

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 biggest talking point about this new car is the engine, with AMG downsizing from the old C 43’s six-cylinder to a 2.0-litre four-cylinder turbocharged petrol engine.

But it’s not just any turbocharged four-pot, because it is fitted with technology that Mercedes claims has been inspired directly from its Formula One team.

While the F1 team engine facility is based in England, this engine was designed and developed by the Mercedes-AMG team at its Affalterbach headquarters, but the concept of the electric turbocharger reportedly comes from the engine that powered Lewis Hamilton to multiple world championships.

The electric exhaust gas turbocharger - to give it its official name - uses a small electric motor on the turbocharger shaft to spin up the blades without having to wait for any exhaust gases to pass through it first.

To power the electric turbo the C 43 is equipped with a mild-hybrid 48-volt electrical system.

Mercedes claims this means reduced lag and improved throttle response for a sportier driving experience. 

It also helps make this small engine produce big amounts of performance, with AMG extracting 300kW of power and 500Nm of torque from this 2.0-litre, which is more power than the previous six-cylinder C 43 managed.

The engine is paired to a nine-speed multi-clutch transmission, which isn’t a dual-clutch with a pair of clutches operating on every second gear ratio, but instead uses a “wet start-off clutch” for better take-offs and smoother shifting on the move (at least in theory).

Power is sent to the road via all four wheels thanks to Mercedes’ 4Matic all-wheel drive system.

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.

Despite the smaller engine you can hardly call the C 43 miserly, with a claimed combined urban/highway cycle rating of 9.1-litres per 100km. That’s only a 0.2L/100km improvement over the old six-cylinder.

On test, which included a return trip from Sydney to Bathurst via motorways and some dynamic back road driving, we saw a return of 11.8L/100km on the car's onboard computer.

While hardly hybrid-worrying, it’s impressive to think that driven modestly, such a potent engine can return a single-digit fuel figure.

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.

Let’s start with the good news. The new Mercedes-AMG C 43 is a quick car. The engine may be small in size but the electric turbocharger does its thing and provides plenty of punch.

You can get a performance boost, too, thanks to the belt-driven starter generator, which acts as a mild hybrid and gives you a surge of 10kW for a brief period if you need a sudden burst of extra speed.

The chassis is well-sorted, too, at least from a dynamic point-of-view. The rear-wheel steering can provide up to 2.5 degrees of turning, which improves handling at speed and manoeuvrability when parking.

However, there are some less-impressive elements to the C 43, too. The obvious one is the drama, or rather the lack thereof.

As I said at the beginning, the C 43 has never been as wild or raucous as the V8-powered C 63, but when you buy an AMG there’s a rightful expectation that it will provide some thrills.

The C 43 simply doesn’t have that character about it. Yes, it’s fast, but it produces that speed with efficiency rather than excitement.

And it’s not an engine size problem, because even the 2.0-litre four-cylinder A 35 and CLA 35 offer more ‘wow factor’ than the C 43.

Yes, the engine makes noise under acceleration (and it can be altered between discreet and sporty) but even at its best it sounds muted and lacks the evocative tone of a V8 or six-cylinder engine. 

Another disappointment is the transmission calibration, with the gearbox awkwardly shifting out of first gear on multiple occasions during our test drive.

In the taller gears it felt smooth enough cruising along, but given its low speed shifts we’d like to spend more time in the urban environment before passing final judgement. 

The other notable element of the driving experience we struggled with was the ride quality. While fine on the smoother motorways, our test drive included time on some patchy country back roads and the C 43, even in the ‘Comfort’ suspension setting, was simply too firm.

Riding on low profile tyres, the adaptive dampers struggled to isolate the cabin from the imperfections in the road, leading to a fussy ride at times.

Overall the C 43 is a good car, but it feels like there are still some areas where Mercedes could improve it to make it really live up to the AMG badge.

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.

The C 43 is covered by Mercedes’ five-year, unlimited kilometre warranty, which has become the new standard for the luxury car market.

Service intervals for the car are at 12 months/25,000km, which is on par with industry standard.

Mercedes-Benz Australia will offer a service plan for the C 43, prices were yet to be confirmed at the time of publication but the company has indicated it will be similar to the C300. 

That means $550 for year one, $900 for year two, the third service costs $1000 and the fourth year service costs $2450 - for a total of $4900 for the first four years of ownership.

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?
