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.

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?

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.

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.

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.

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.

Audi has not revealed pricing or Australian specification for the 2025 e-tron GT as it’s not set to arrive Down Under until some time in the first half of 2025.

However, pricing has crept up a little in Europe so expect the same here. For reference, current pricing starts at a tick over $181,000, before on-road costs, and climbs to $250,000.

Previously there were just two grades - the entry-level (if you can call it that) e-tron GT and the top-spec RS e-tron GT. Audi has increased the range from two to three grades. 

The new entry point is called the S e-tron GT, followed by the RS e-tron GT, and now Audi is offering an RS e-tron GT ‘performance’ grade.

This is the first fully-electric Audi RS to get the ‘performance’ tag that’s found on other models like the RS6 Avant. The performance model is also the most powerful production Audi model ever made.

Audi Australia is believed to be considering all three grades for a local launch. 

As mentioned, standard gear is yet to be confirmed but expect items like wireless phone charging, sports seats, electrically adjustable driver’s seat with memory function, a head-up display and more.

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 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.

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.

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.

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.

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.

The e-tron GT is a little too niche to warrant crash testing by ANCAP or Euro NCAP so it doesn’t currently have a score.

It comes with safety gear like lane change warning with exit warning and rear cross-traffic alert, adaptive cruise with a speed limiter, surround view cameras, AEB, swerve assist and more.

Full local specs will come ahead of the 2025 local launch.

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.

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.
