Audi E-Tron Gt vs Mercedes-Benz CLA-Class

What's the difference?

While it may be a very different beast to the R8 supercar, it’s hard to argue that the e-tron GT offers performance that isn’t equal to anything Audi has previously produced. The immense acceleration and power, coupled with the brilliant and clever handling make this updated range, especially the RS pair, feel like something special.The fact that it will save you visiting a petrol bowser and might help cut harmful emissions is just a bonus.

The broadening of the CLA’s scope in this third-gen version puts it a step ahead of key rivals and raises the compact sedan’s prominence in the three-pointed star’s local line-up. Its combination of quality design, performance and efficiency is compelling. And we’ll drive the battery-electric version as soon as it lands.

While there are some big changes underneath, on the surface the design tweaks are quite subtle. 

There are some tweaks to the front grille, headlights, lower bumper and air intakes, but overall the look isn’t dramatically different. The more noticeable styling change is between the S and RS models, with the latter looking more sporty and dynamic thanks to a unique lower bumper design and the larger alloy wheels, which have a sportier look.

The biggest design changes are arguably the introduction of the switchable transparency roof on the RS and the option to use matt carbon camouflage.

The former is another shared element between the RS e-tron GT and Taycan, and it uses a special glass that can switch between being clear or opaque depending on whether you put a current through it. Cleverly, Audi is offering the option to have individual sections alternate between the two states, so you can customise it to your preference.

As for the grandly named matte carbon camouflage, it wasn’t highlighted in Audi’s presentation, but it’s the same material the Lamborghini developed over a decade ago and calls ‘forged carbon’ instead.

Unlike traditional carbon-fibre, which is made from injecting resin into sheets of fabric-like carbon fibre weave, forged composite uses a malleable paste of carbon sheets and resin. This technique is quicker to make and easier to shape into complex pieces, but lacks the visual impact of conventional carbon-fibre.

The biggest design change internally is the new steering wheel, which is a not-quote-squared-off rim that feels nice in your hand without being too thick. The RS models feature two new large red buttons - ‘RS’ and ‘Boost’ - which allow you to select the drive modes and activate the short boost function, respectively.

In an impressive feat of aero fine-tuning Mercedes-Benz design and engineering teams have managed to make an already slippery car even more efficient with this new CLA dropping the car’s drag-coefficient from 0.23 to an amazing 0.21.

The sloping, coupe-style profile remains as a CLA signature, complete with frameless doors, flush door handles and aero wheels. 

Hybrid variants sport a conventional radiator grille decorated with a Mercedes-Benz star pattern in chrome and illuminated around its perimeter, while the EVs feature a fully illuminated LED grille display.

And in a move perilously close to branding overkill, the three-pointed star motif is carried into the headlights and tail-lights.

For Latin buffs the interior treatment is minimus extremus, the multi-screen ‘MBUX’ array in the CLA220 we drove dominating the front part of the stripped-back cabin.

From an ergonomic point-of-view, there are no physical controls for ventilation and the only non-digital audio control is on the steering wheel.

But aesthetically, the cabin is clean and simple with touches like ‘floating’ door armrests and a gently rounded front centre console adding to an overall relaxed atmosphere.

Practicality is an important consolidation for the e-tron GT, it may have replaced the two-seater R8 as Audi’s definitive performance hero, but it’s a four-door sedan so it needs to be more family friendly. It’s especially relevant for Audi, as the brand has a history of brilliantly combining family needs with fast cars, namely its iconic wagons, the RS4 and RS6 Avants.

Audi also has a strong reputation for some of the best interior design in the industry, and the e-tron GT is arguably amongst its best work (at least in this reviewer’s opinion). It looks modern and stylish without leaning too far towards being different simply because it’s an electric car.

The new steering wheel fits the new design well, framing the digital driver’s display nicely. The display itself has a new RS-specific display for the higher-end models.

There’s a central infotainment touchscreen, but underneath this particular Audi skips the climate control touchscreen in favour of a digital readout and physical switchgear; a welcome relief for some, no doubt.

As for the seats, all three trim levels get the same style of sports seat trimmed in Nappa leather with a honeycomb stitch pattern. There are different finishes, both black and red leather, and some with contrasting stitching available through the optional design package. The RS performance package gets a unique ‘serpentine green’ stitching to stand out.

Small item storage in the front is adequate but not generous, which does make the e-tron GT feel more like a sports car at least, even if it doesn’t help practicality.

As for the rear, space is surprisingly good given the external dimensions and the nature of it being a low-roof sedan (rather than an SUV) with batteries underneath the floor. That’s largely because Audi has split the battery pack to allow for extra room in the rear for passengers’ feet, combating a common problem with electric sedans.

Headroom is adequate, and will be tight for anyone much taller than 180cm, but it will do the job of transporting the family in relative comfort. It is, by no means, the most spacious or family friendly model in the Audi range, but it does play its role as both a performance car and roomy sedan.

The boot is measured at 405 litres in the S but shrinks to 350L in the RS models, but both have the same 77L space under the bonnet, so space is (again) reasonable without being generous.

At just over 4.7 metres long the CLA isn’t a million miles away from full C-Class length and interior space is generous. In fact, there’s an extra 16mm in height and 12mm in width compared to the model this car replaces.

And in terms of storage there are generous bins in the doors with room for bottles and you can place them in one of the two cupholders in the centre console.

There’s the obligatory bin between the seats, a bay here for wireless device charging and a glove box, plus an extra storage bay under the flying buttress-style console.

In the back seat sitting behind the driver’s seat, set for my 183cm position and there’s plenty of footroom as well as acres of legroom and headroom. 

And part of that is the immense panoramic roof which is covered in all kinds of high-tech coatings to make sure all the light comes through but none of the heat.

Then for storage, again you’ve got bins in the doors with room for bottles as well as a pull-down armrest between the seats with three cupholders in it (one espresso-sized) and drive slot in front of them.

There are netted map pockets on the front seatbacks, individual vents which are always welcome and a couple of USB-C charging ports to keep devices charged.

Boot volume is rated at 405 litres (VDA) and the rear seatback folds 40/20/40 to liberate more storage space if required. And there’s a 101L front boot on electric models. 

There’s a hands-free tailgate on the 220 Hybrid. A 1.6- to 1.8-tonne braked trailer towing capacity is handy, but the fact there’s no physical spare tyre isn’t. Your only option in the case of a flat is an inflator and puncture sealant kit. Not good enough.

The Mercedes CLA kicks off at $66,500 for the entry-level 180, with two other hybrids above it - the CLA200 at $68,100 and CLA220 4Matic sitting at $84,300, all before on-road costs.

Prefer pure-electric? The CLA200 electric will set you back $72,200 with the flagship CLA350 4Matic electric at $91,300.

Which puts the range in the same price ballpark as its German ‘Big Three’ rivals, the Audi A3/S3 sedan and BMW 2 Series Gran Coupe.

Aside from the safety and performance tech we’ll get to shortly, standard equipment in the CLA180 includes heated power front seats, synthetic leather trim, a fixed panoramic glass roof, ambient lighting, ‘high performance’ LED headlights, keyless entry and start, park assist, 18-inch alloys and metallic paint. And the AI-powered assistant integrates ChatGPT, Google Gemini and Bing technologies.

Move up to the CLA200 and you pick up AMG Line elements including different (still 18-inch) rims, sports seats, synthetic leather and synthetic suede trim, a multi-function sports steering wheel, carbon-grain aluminium trim pieces, AMG body styling and what Merc refers to as ‘a sporty engine sound’ driven through the audio system.

Then, aside from its all-wheel-drive powertrain, the CLA220 4Matic includes the ‘MBUX Superscreen’ (combining a 10.25-inch driver display and 14-inch central media touchscreen), a rear light strip, 16-speaker, 850W Burmester 3D surround audio, ‘Multibeam’ LED headlights, 19-inch AMG rims, a head-up display, hands-free boot functionality and privacy glass.

No surprise, the CLA200 electric’s spec is largely the same as its hybrid counterpart, while the CLA350 4Matic electric matches its extra dual-motor performance with the larger 19-inch wheels.

All in all, a decent rather than class-leading list of included features for the class.

There are two option packages. The ‘Premium’ bundle is essentially the standard spec of the CLA220 4Matic, so it’s $0 on that grade but adds $1800 to the hybrid or electric CLA200 and $2340 (including LCT) to the CLA350 4Matic electric.

Similarly, the ‘Sport’ package consisting of privacy glass and 19-inch rims is standard on the CLA220 4Matic but adds $1200 to the price tag on the CLA200 (hybrid or electric).

The key number for the new model is 680kW - that’s what the new RS e-tron GT Performance produces from its dual electric motors. That makes it the most powerful production car Audi has ever offered, which is quite an achievement when you look back at some of the cars this brand has built over the years.

That power upgrade is an extra 205kW over the pre-facelifted RS e-tron GT, and comes with a whopping 1027Nm of torque.

The RS e-tron GT has been upgraded too, now making 630kW/865Nm, a 155kW improvement on the old model. Which is a good thing, because the new S e-tron GT has even more power than the original RS, underlining just how much Audi has focused on power for this mid-life enhancement. The new S packs a 500kW/717Nm punch, compared to the 475kW/830Nm the previous RS offered.

Hybrid CLAs combine a 1.5-litre, turbo-petrol, four-cylinder internal-combustion engine (ICE) with a 48-volt electric motor integrated into a new eight-speed dual-clutch transmission with drive going to the front wheels in the CLA180 and 200 and all four in the CLA 220 4Matic.

Mercedes-Benz quotes power and torque outputs for the hybrid’s petrol engine and electric motor individually and the powertrain is able to engage both simultaneously so there are overall output figures, as well. 

The pure-electric models are powered by an in-house developed permanently excited synchronous motor driving the rear wheels through a two-speed transmission, with a second 80kW drive unit added to the CLA350’s front axle for extra performance and all-wheel-drive traction. 

Here’s a panel to explain it all.

Another one of the significant unseen changes for this update is the battery. Audi has overall the battery for this latest e-tron GT, so it now has higher energy density (168.3Wh/kg), more size (105kWh v 97kWh), faster charging (10-80 per cent in 18 minutes) and reduced weight (down 9kg).

Despite all the extra power, driving ranges for the three models are still all beyond 500km. The S e-tron GT has a claimed range of 558km, the RS e-tron GT can manage up to 522km and RS e-tron GT Performance can run 528km on a single charge, according to Audi. 

As for the charging itself, Audi claims it now takes just 18 minutes to get from 10 to 80 per cent using an ultra-fast DC charger.

Hybrid CLAs are fitted with a 48-volt, 1.3kWh lithium-ion battery and at urban speeds where less than 20kW is needed, can drive using electric power alone, depending on conditions at speeds up to 100km/h. 

Official combined cycle fuel consumption is quoted at 5.4L/100km for the CLA180 and 200, which equates to a theoretical range of close to 800km, rising to 5.8L/100km for the 220 4Matic for a potential range of around 740km. 

On the roughly 150km launch drive through Melbourne's suburbs and up the Yarra Valley north-east of the city we saw an average of exactly 5.8L/100km in the CLA220.

Electric CLAs are underpinned by a specific new-gen EV platform boasting an 800-volt electric architecture and housing an 58kWh LFP battery in the 200 electric and an 85kWh NMC pack in the 350.

Maximum charge capacity is 320kW for a claimed 10-80 per cent charge time of 22 minutes. 

Claimed energy use for the CLA200 electric is 14.4kWh/100km with a range of 470km while the AWD 350 4Matic sits at 14.9kWh/100km with a range of 663km.

Befitting its role as Audi’s performance hero, the new range drives with a level of speed and precision you would expect from such a car.

Even the new S e-tron GT has a level of acceleration that not every sports car could keep up with (the official 0-100km/h claim is 3.4 seconds), which would be impressive on its own but is a standout when you consider this is a four-door sedan.

It also helps that the adaptive air suspension and all-wheel steering (which can help both low speed manoeuvring and high speed changes of direction) make for an incredibly responsive and agile handling vehicle.

And then you drive the RS e-tron GT Performance and the driving experience is a step up again with its 2.5s triple-digit sprint time. That’s largely because of the new active suspension system it uses, which features a hi-tech array of cameras, radars and sensors to ‘read’ the road ahead of it and adjust the ride accordingly.

The result is arguably one of the best riding, most comfortable electric performance cars on sale today. Typically the need to control so much weight, from the batteries, means the ride is often too firm. But with the active suspension, Audi has somehow managed to make the ride both compliant (on 21-inch wheels) but also very well controlled, which allows you to really drive with precision even at speed.

But it’s not just the suspension, as mentioned earlier, the RS models also get a new ‘Boost’ button on the steering wheel that offers an extra 70kW of power for 10 seconds. Along with the surge of extra performance there’s a large countdown timer on the digital dashboard when you press it to really give you a sense of urgency and speed.

Thankfully, with so much power the e-tron GT range has plenty of stopping power. The S comes equipped with steel brakes, which do a fine job. But for the faster RS models, you get a carbide coated rotor and you can option ceramic brakes for more resilient stopping power.

The CLA220 4Matic was the only option available for the drive program, but for the record, claimed 0-100km/h acceleration times for the hybrid models step down in roughly one second increments - 8.8 seconds for the CLA180, 8.0sec for the 200 and 7.1sec for the 220 4Matic.

Switch to pure-electric power and the CLA200 electric hits the same speed in 7.5 seconds, while the 350 4Matic electric smashes the five second barrier at a properly quick 4.9sec.

Mind you, the 350 4Matic electric weighs about 2.1 tonnes while the hybrids tip the scales at roughly 1.7 tonnes.

There’s plenty of performance in the 220 4Matic but power delivery is not always linear with the powertrain taking half a beat to pick up after you’ve applied some throttle. Which could be the interface between the combustion engine and the electric motor or the turbo on the engine.

The sports steering wheel is grippy and chunky in the hands, and while the steering itself is nice and accurate, road feel is modest. 

There are two settings for steering weight - Comfort and Sport. We tried both, and yes, you can feel where the car’s going but it’s not exactly an intimate connection between your hands and the front tyres on the tarmac.

Speaking of which, standard rubber on the CLA220 is 225/40 Bridgestone Turanza 6 on 19-inch rims and despite those relatively large wheels the car copes well with bumps and thumps and the coarse-chip surface of rural B-roads.  

Suspension consists of a newly-developed strut-based three-link set-up at the front and multi-links at the rear with all of the major components in alloy to minimise unsprung weight.

The car remains composed and balanced through corners and the sports seats in the 220 are grippy, supportive and comfortable. We spent a couple of hours straight behind the wheel without a hint of discomfort.

The CLA’s super-slippery shape manifests itself out on the highway with minimal wind noise at 100km/h and even more. The big tyres are also quiet so the cabin environment remains refined and peaceful.

Brakes on the 220 are vented discs on the front, solid rotors on the rear. And during some pretty challenging downhill twisty sections we leant on them quite heavily. Push hard and they will bite but are not overly aggressive.

The lane-keeping, driver-monitoring and other assistance features are all there, present and accounted for. But more than ticking the box, they work very well.

The media system is driven by a high-capacity unity engine which is often used in gaming and the graphics and animations are super-smooth. And the latest iteration of the Mercedes-Benz media system works nicely across the enormous screens.

All models feature a 360-degree overhead view and a reversing camera and the 11.2-metre turning circle is not small but not vast. The car is easy to manoeuvre and park.

The new CLA hasn’t been assessed by ANCAP although its sister organisation, Euro NCAP, awarded it a maximum five-star rating in 2025 with mega high scores across the board for occupant and pedestrian protection as well as driver assist systems.

Active (crash-avoidance) tech highlights include auto emergency braking (AEB), blind spot monitoring, lane keeping assist, adaptive cruise control, parking assist, ‘Exit Warning’, ‘Evasive Steering’, ‘Maneuvering Assist’ and more.

Worth noting over-the-air updates cover safety systems, including driver assistance functions.

The airbag count runs to eight, including a front centre bag and there are three top tethers for child restraints across the second row with ISOFIX anchors in the two outer positions.

Audi offers its standard five-year/unlimited kilometre warranty for the three e-tron GT variants, but the battery gets a specific eight year/160,000km warranty. The five years of coverage is fairly standard for the luxury car segment, but short of the increasingly common seven-year warranties for mainstream brands.

As for the servicing, that’s included in the cost of the car, with Audi covering the first six years of maintenance for no additional charge. It helps that service intervals, without a complicated and oily engine, are stretched to two years or 30,000km.

The CLA is covered by Mercedes-Benz Australia’s five-year/unlimited km warranty with roadside assistance included. On top of that, there’s an eight-year/160,000km warranty on the drive battery in electric models.

That general warranty is in line with Audi, BMW and other premium players, but it’s worth noting an increasing number of brands in the mainstream market are stepping up to longer seven, eight and even 10-year cover.

Hybrid and electric variants have the same 12-month, 25,000km recommended service interval with a five-year schedule for the hybrids equating to an average of $1342 per workshop visit over that period. Reduced mechanical complexity in the EV models lowers that number to $859. But neither is especially cheap in the context of class competitors.
