Mercedes-Benz C43 vs Mercedes-Benz CLE

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.

The AMG CLE 53 4Matic+ is formidable yet friendly, ferocious yet refined and fun yet functional.

Yes, the price is edging up to previous 63 flagship levels, and it can become a bit noisy inside, but the four-seater coupe’s specification, speed, sophistication and balance are compelling reasons to consider this if your shortlist also includes an Audi RS5 or BMW M4.

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.

Crisp and aero clean with a handsome fastback silhouette, the CLE’s design is very much in the mould of a modern-day C-Class coupe, but with larger proportions in line with what a contemporary E-Class coupe would look like.

It employs the same architecture as the W205 C-Class and W214 E-Class sedans.

Length, width, height and wheelbase measurements are 4850mm, 1861mm, 1423mm and 2865mm, respectively.

Wearing the AMG suffix means the CLE 53’s body differs in small but important ways to the regular C236 coupes.

The front end, for instance, adopts what Mercedes calls a ‘shark nose’ look, for a suitably more macho visage, with vertical slats in the grille and larger air intakes that ultimately aid cooling and performance.

Meanwhile, the tracks are broader by 61mm at the front and 45mm at the rear, and are matched by mudguards that are 58mm and 75mm wider, respectively. This certainly gives the AMG a hunky appearance.

Speaking of which, further AMG visual titivations include a discernibly larger bulge on the bonnet feeding into (functional) side air vents, along with 20-inch specific alloy wheels, as well as a 'Night Package' I and II, comprising black trim elements all around.

A model-specific wider body kit, lip spoiler, twin pairs of tailpipes, diffuser insert and 20-inch AMG alloy wheels complete the CLE’s gymnasium makeover.

Result? The sleek and muscular body’s extra girth, fatter footwear and darkened highlights make the 53 look as menacing as any AMG forbear, setting a very high bar for the CLE 63 to beat when it eventually surfaces. Great work, Affalterbach!

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 interior dons a C-Class-in-drag-race do-over. Frankly, the latest – and much more modern-looking – E-Class sedan’s dashboard would have been preferable, however, given its tech-heavy panorama of screens.

For its AMG 53 outing, the cabin boasts an AMG-specific steering wheel with performance mode knobs, a 12.3-inch driver display brandishing a variety of instrumentation styles (including 'Race', 'Sport', 'Classic' and minimal screens) and a multimedia system with track telemetry data within a tablet-style 11.9-inch touchscreen.

There's also electric and heated ‘integral’ sports seats with memory, 'Anthracite' trim elements set against high gloss black inserts, 64 questionable shades of ambient lighting and banging Burmester premium audio with no fewer than 17 speakers.

This is a roomy and well-presented cabin, offering space to spread out up front, a superb driving position, exceptional seat support, quality materials and a decent level of practicality.

Storage is plentiful, most switchgear is within easy reach and the multimedia system is easy to fathom after you’ve taken the time to familiarise yourself with it.

On the other hand, the glossy plastics do not look or feel as elevated as, say, a Porsche’s interior, the air vents feel flimsy to the touch, while trim squeaks were occasionally heard over some rougher road surfaces. It’s not as solid as you’d expect from a Mercedes at this price point.

Rear access is tight due to a slim aperture, as almost all coupes are, but once sat on the contoured rear bucket seats, most adults should find it tolerable unless they’re especially long-legged or over 185cm or so tall.

Further back, a handy 410-litre boot is provided, with a folding rear seat backrest to boost cargo capacity even further, underlying the CLE’s family-friendly packaging.

Note, though, that this is 10L shy of the regular non-AMG models, and smaller than the Audi RS5 (465L) or BMW M4's (440L) boot.

Plus, no spare wheel is available – just a tyre repair kit.

Starting from $158,900 (all prices are before on-road costs), the 330kW/560Nm CLE 53 4Matic+ is an AMG product with a reputation to uphold. Thus, it comes with performance-enhancement items, like all-wheel drive, four-wheel steering (4WS), adaptive dampers and variable-ratio steering. 

Additionally, for Australia, the 'AMG Dynamic Plus Package' is standard, bringing a 12-second over-boost that bumps torque up to 600Nm and special engine mounts that harmonise with the adaptive dampers for better performance response.

There's also a ‘Race’ mode offering maximum power and traction-off settings for track-work shenanigans, a brand-specific steering wheel with fast-access driving-control buttons, performance telemetry data display, galvanised paddle shifters, and 20-inch AMG alloys shod with performance tyres, amongst other goodies.

These come on top of LED headlights (with 1.1 megapixels of light), a head-up display, panoramic sunroof, 12.3-inch customisable digital instrumentation, a driver-orientated 11.9-inch touchscreen display, 64-colour ambient lighting, heated electric front seats, dual-zone climate control, wireless charging, Apple CarPlay/Android Auto integration, 17-speaker Burmester premium audio, powered boot closing, a 360-degree surround-view camera, adaptive cruise control, 10 airbags and Mercedes’ 'Pre-Safe' accident anticipation system. More on that in the safety section below.

Fairly well equipped for the money, then. April 2025 brings a cabriolet version, as well.

Option packs include an $8900 'Carbon Package' with carbon-fibre exterior elements and 'AMG Performance' seats at $5400.

These features are in line with the equivalent Audi and BMW coupes.

And while the pricing is only about $10K shy of the 331kW/600Nm RS5 and around $15K short of the 353kW/550Nm M4 manual flagships.

The latter, in blistering 390kW/650Nm M4 auto guise, starts from $190K, neatly opening up the gap for the coming CLE 63 – and that’s going to come with a V8 hybrid, we hear.

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.

Under the bonnet is a 3.0-litre, in-line, six-cylinder petrol engine. Mercedes-AMG calls it “double charged”, with a single, 1.5-bar turbo augmented with an electric compressor as part of a 48-volt Integrated Starter Generator (or ISG).

The latter makes 17kW of power and 205Nm of torque, for a system total of 330kW at 6100rpm and 560Nm from 2200-5000rpm. Up to 600Nm is possible thanks to a 12-second overboost.

It also recuperates brake energy, offers “almost imperceptible” stop/start fuel saving and allows for an off-throttle, engine-off ‘sailing’ mode.

Not interested in economy? Tipping the scales at a hefty 2015kg the CLE 53’s power-to-weight ratio is a sparkling 164kW/tonne.

All Australian-bound CLE 53s feature the Dynamic Plus Package, with a launch-control function that helps deliver an eager 0-100km/h sprint time of 4.0 seconds. Top speed is governed to 250km/h.

Drive is sent to all four wheels via a nine-speed torque converter automatic transmission. It can simulate double-declutching and offers variable shift modes according to drive settings.

The AWD system, meanwhile, varies torque from 50:50 front/rear to 100 per cent rearwards.

To aid handling, the 4WS system allows the rear wheels to turn in the opposite direction to the fronts, up to 2.5 degrees at up to 100km/h, and 0.7 degrees in unison with the fronts above that speed.

Keeping things in control is a four-link front and five-link independent rear suspension set-up, with AMG ride control featuring adjustable dampers and sports spring rates.

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.

Considering the performance on offer, the CLE 53’s 9.6 litres per 100km combined (urban/extra-urban) cycle fuel consumption rating is not too bad. That equates to a carbon-dioxide emissions figure of 219 grams/km. City/highway numbers are 13.2 and 7.6L/100km.

With a 65-litre fuel tank filled with 98 RON premium unleaded petrol, expect an average range of about 685km.

What did we achieve? Driven fairly hard on some of Tasmania’s most beautiful rural roads, the trip meter showed an indicated 9.5L/100km.

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.

The new AMG CLE 53 might look much like several of its AMG 63 predecessors, with its brutish stance and bulging bits, but does the German performance coupe drive and feel like an AMG flagship?

With a 63 range-topper (as yet unconfirmed) in the pipeline, that’s a bit of a moot point here, because that will be an altogether harder, faster and more expensive proposition.

But we can tell you that, even without the bellowing V8 of old, the 53 does a damn-fine impression of a charming high-performance GT with the straight-six .

At the heart of the matter is the inline six-cylinder turbo-petrol engine incorporating an electric compressor working the lower revs for punchy off-the-line acceleration and a big twin-scroll gas turbo for more-instantaneous responses further up the rev range.

This makes for an impressively rapid real-world tearaway. Not brutally fast in the way even middling EVs can manage to be nowadays, but still with an urge and character that puts you in the mood for speed.

The steering, meanwhile, is alert, faithful and remarkably reactive, with that 4WS rear end tucking in neatly through the tight turns and twisty bits, allowing a feverish pace with a pleasing grace to be maintained.

Assisting that immersive agility is an almost unshakable sense of grip – no surprise given the variable-torque AWD as well as the late-summer warmth and dryness of the roads we were testing on.

Yet, even beyond these factors, it’s clear the AMG’s immense roadholding provides a reassuring layer of confidence and control.

No opportunity was provided to unleash the CLE 53’s full fury on a track, so we can’t tell you how easily sideways or catchable this thing steers in Race mode with all the safeties turned off, but this coupe’s dynamic bandwidth was obvious during the all-too-few occasions we did manage to fang it.

Another positive is the suspension’s ability to soak up the bumps without too much disturbance inside, allowing for easy and effortless cross-country touring. No truly terrible roads were encountered during our half-day in this civilised beast, though, so we’ll have to reserve our judgement on whether this is the comfortable all-rounder that Mercedes claims it is.

What we can tell you is that there is too much road-noise intrusion inside an otherwise isolated cabin. And we’re no fans of the lack of a spare wheel – an absolute necessity in Australia.

Still, first impressions are very positive.

Its maker calls the CLE 53 the AMG for all occasions, and we cannot argue with this logic.

That there’s a decent wad of thrills and emotion on offer to counterbalance this car’s comparative refinement and civility just proves there is a place for the penultimate version of this series.

Unlike its maximum five-star ANCAP-scoring C- and E-Class cousins, the CLE comes with no rating.

But the brand’s boundary-pushing reputation on this front does hold the coupe in good stead, backed up by a slew of active, passive and driver-assist safety features.

These include wide-spread autonomous emergency braking (AEB) and lane-support systems, as well as Mercedes’ 'Pre-Safe' tech that anticipates a crash and prepares the car for impact.

Other tech includes 'Active Lane Change Assist', 'Active Lane Keep Assist', 'Cross-Traffic Assist', blind spot monitoring, active brake assist, traffic sign assist, active-distance-assist, adaptive cruise control, evasive manoeuvre support, 360-degree camera views, 10 airbags, adaptive high beams and a 1.1-megapixel LED lighting set-up.

In other contemporary Mercedes models, AEB operating parameters are roughly between 7.0-80km/h for pedestrians and cyclists, and from about 7.0-250km/h for vehicle-to-vehicle, while the lane-keep support systems operate between about 60km/h and 200km/h.

ISOFIX child-seat anchorages are located in the front passenger seat and two in the rear seats.

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.

Somewhat average for most mainstream and luxury brands, Mercedes-Benz offers a five-year/unlimited km warranty, with five years of roadside assistance.

Intervals are every 12 months or 25,000km, and while no capped priced servicing is offered, pre-paid three-, four- or five-year service plans are available, ranging from $4190, $5310 and $7760, respectively at the time of publishing.
